TRUTHEAR GATE : Everything is adequate, no need to complain, comfortable
Hey guys! Here we have an IEM that I find quite interesting, both in terms of design and sound quality.Could this be a recommendation? Maybe. Personally, I quite like this IEM, though if you're looking for something exceptional, there isn't much that stands out. Similarly, there aren't many complaints either—there’s not much to criticize about this IEM.
We're actually a bit late reviewing this, as others have already done so about two or three months ago.
Alright, let's get started. Here's my review of the Truthear Gate.
DISCLAIMER & THANKS TO
First off, I want to say a big thank you to Intium Indonesia for providing the IEM unit for this review. For those of you in Indonesia looking for an IEM and often ask, "Bro, any recommendations for a store with good service and a clear warranty?" You can check out this store. If you're in the DKI Jakarta area, especially North Jakarta, you can also drop by Intium Indonesia’s physical store—yes, they have a physical store, not just an online shop.
As always, this review is going to be very subjective, based on my personal taste and impressions after using this IEM for about 3 weeks, while also comparing it to my other IEMs. Intium just entrusted us with the IEM for review, without any specific brief or requests.
PRICE
The price of the Truthear Gate is around Rp350.000 IDR in Indonesia, which is around $20 or $22 USD.
SPECIFICATIONS
For the specifications, this IEM uses a 10mm Single Dynamic Driver configuration, which they claim features their latest technology, the Carbon LCP Diaphragm. It has a sensitivity of 122dB, impedance of 28 Ohms, and a frequency response range up to 45,000 Hz. The cable is detachable, using the standard 2-pin 0.78mm connection.
PACKAGING
The packaging is attractive, and it has become a trend for Truthear and Moondrop to include anime characters or waifus on the front cover. Truthear models like Hola, Hexa, Shio, Zero Blue, and Zero Red, as well as Moondrop Chu, all feature anime art.
On the back, we're presented with a frequency response graph, which is somewhat similar to the Simgot EW100P, if I remember correctly. At the bottom, there’s a brief overview of the specifications.
The top, bottom, and sides are predominantly black, with only a bit of text present.
INCLUSIONS
As for the inclusions, they're pretty standard—nothing too special.
- The IEM unit is the Truthear Gate; we have the black version here, but if you prefer white, it's also available.
- The cable unit has a 2-pin connector and a 3.5mm single-ended jack.
- The eartips include 7 units: 3 small bore and 4 wide bore.
- Lastly, there's a pouch for storing or carrying the IEM.
BUILD QUALITY
As for the build quality of the IEM, it’s actually quite standard. Everything is made from resin or plastic, from the housing and faceplate to the nozzle. The resin isn’t particularly high quality, but I do like the appearance of the faceplate, which is very clear and transparent. Although, to be honest, there’s nothing special about the internals. It does allow us to see the dynamic driver, internal wiring, and connectors. This transparent design seems to be quite popular right now; I also have the KZ Merga and KZ Libra with a similar clear design.
What bothers me a bit is the placement of the "Gate" lettering and the Truthear logo. Why is it placed so far to the edge? It would have looked better if it were slightly more centered. I don’t know if it’s my OCD or what, but it’s frustrating to see the placement look so random.
Also, if the shape of the dynamic driver had a cooler design, like the internal dynamic driver of the KZ Merga or even the EDX Lite, which has a plate that looks like a racing car wheel at the top, it would look much better than this very plain design.
But overall, there are no issues with the build quality, even though there’s nothing to be particularly proud of either. It’s just average.
The eartips are also pretty standard, made of black silicone. We get 4 pairs of wide bore tips and 3 pairs of small bore tips. As you probably know, this will significantly affect the sound. The small bore tips will provide a warmer sound compared to the wide bore tips, which will direct the sound more towards a brighter or more open character.
The cable is quite good for my taste; it features an OFC material for the internal wiring and is covered with a black rubber-like material, making it flexible, not stiff, and resistant to tangling.
What I particularly like is that it comes with a volume button, which is something that's becoming quite rare in other IEMs. In fact, as far as I remember from all the IEMs I've reviewed on my YouTube channel up until this review was written, this is the first one that includes a volume button on the microphone.
This is really helpful when we’re listening to music from our phones, as we don’t have to adjust the volume on the phone itself or through the volume button on the DAC dongle. We can just click the volume button on the cable, which is simple but very useful.
The jack is L-shaped, gold-plated, and has 4 poles.
The connector from the cable to the IEM driver uses the standard 2-pin 0.78mm model.
You can listen to the audio recording from the microphone on my YouTube channel.
As for the pouch, I think it’s nice because at this price point, many other IEMs only provide a simple pouch made of velvet fabric.
Truthear consistently offers a pouch made of synthetic leather like this, which is a great touch. It’s similar to the pouches that come with the Truthear Hola, Hidizs MS3, and Hidizs MP145, which all feature the same design.
FITTING
In terms of fitting, these IEMs are very comfortable. The shape of the housing is not unusual, and once inserted into the ear, they immediately find a good fit. The seal is sufficient, the grip is adequate, and they feel relatively lightweight. The resin cuts and joins are smooth, with no rough edges.
SOUND QUALITY
When it comes to sound quality, let's discuss it while comparing it to other IEMs. This time, I’m reminded of an IEM we reviewed on YouTube about a year ago: the Simgot EW100P, which was one of the early releases when Simgot became more aggressive in the market.
If you’ve already listened to the Simgot EW100P and remember its tonal characteristics well, you can skip this review because the sound is quite similar. However, the technical aspects here are slightly better.
Low / Bass
In terms of low frequencies or bass, this IEM follows a Harman Target-like tuning, providing a sufficient quantity for both sub-bass and mid-bass. You can definitely feel the impact as the bass hits, creating a sensation of air pushing against your eardrums. The low frequencies are well-represented, but they aren't overly aggressive.
The transient speed is decent—not slow by any means. Whether you're listening to fast-paced metal tracks with double pedals or intense bass-heavy EDM songs, it handles them without falling behind. However, it doesn’t deliver an overwhelmingly satisfying experience with heavy bass; it’s not boomy or rumbling. Overall, the bass performance can be described as versatile—suitable for various genres but not specifically tailored to excel in any one of them, while still being enjoyable across different musical styles.
What’s clear is that the Gate offers clean and well-controlled bass that doesn’t interfere with the mids or vocals.
Mid & Vocal
In the midrange and vocal performance, male vocals sit nicely in the center, presenting a balanced position without being too recessed. On the other hand, female vocals are slightly more forward in the mix. The thickness of the vocals feels just right, again delivered cleanly without being dry. The articulation of each lyric is clear, although shoutiness can occasionally occur in certain tracks with a lot of screaming. The emotional dynamics are well-captured, but when the shouting becomes excessive, it can introduce a bit of shoutiness. However, the sibilance in the articulation of "S" sounds is relatively safe.
Overall, the vocals on the Truthear Gate feel dynamic yet light, transparent, and clear. They share similarities with the vocals on the Simgot EW100P, but here, you won’t encounter the graininess that can sometimes be present in the Simgot EW100P.
Other midrange instruments, such as guitars and pianos, are also presented clearly and maintain a good position in the mix, not overshadowed by the bass. Overall, the sound remains clean and transparent, similar to how the vocals are represented.
High / Treble
For the high frequencies or treble, the Truthear Gate offers a satisfactory performance. It doesn’t make the overall sound of the IEM dark at all; there’s no sense of darkness here. However, it also doesn't come off as overly sparkling or excessively crisp. Once again, there are similarities to the treble of the Simgot EW100P, which provides decent detail without being overly aggressive or piercing.
Cymbals maintain a fresh and vibrant sound, without reaching a harsh or sharp level. When it comes to violin performances, like Lindsey Stirling's "Carol of the Bells" or "The Arena," they remain enjoyable, though they may lack the biting intensity found in models like the KZ Castor Harman, TRN Conch, or CCA CRA series. Overall, the treble strikes a nice balance, providing clarity without overwhelming the listener.
TECHNICAL PERFORMANCE
For the technical aspects, the Truthear Gate doesn't stray far from other IEMs in the 200 to 300 thousand IDR price range, but it offers a slight improvement over the Simgot EW100P, which has a similar tonal profile. The soundstage is quite spacious, with good instrument separation and clarity, allowing each instrument to be heard distinctly.
The overall clarity is good, though not on par with the EW200. However, it's still considered clean and clear, with solid resolution from low to high frequencies. The imaging is also satisfactory, not too flat or overly three-dimensional, providing a satisfying listening experience.
CONCLUSION
In conclusion, this IEM is tuned safely, with its technical aspects aligning well with its tonal quality and price. It can be used for listening to a wide variety of music but isn't particularly specialized for any specific genre. My conclusion is similar to the EW100P that I reviewed about a year ago; the special feature of this IEM is its minimal complaints regarding fitting, tonal quality, and technical performance. Although technically, it is slightly better than the EW100P.
Overall, in terms of tonal balance, for those of you who have a diverse playlist listening to various genres—ranging from Pop, Rock, Dangdut, EDM, Classical, Instrumental, to J-Pop and K-Pop—the Truthear Gate is an all-rounder. It won’t make any of those genres sound significantly worse, providing a comfortable listening experience. However, it doesn't excel in any specific genre either.
For basshead friends, it’s clear that the Truthear Gate won’t deliver the booming bass found in the Castor Bass or the punchiness of the CCA Polaris. However, the Gate does present a cleaner bass response while still reaching lower frequencies. It just doesn’t have that same thickness in the bass.
For those of you who are mid-centric or vocal-centric listeners, the Truthear Gate might still be a good fit. However, if I personally want to focus solely on vocals without worrying about the bass, I would still prefer the Tanchjim Zero.
As for trebleheads, this may not be the ideal choice. However, for those looking to obtain good detail without the crunchiness, the Gate should work well. It strikes a balance that offers a pleasant listening experience without overwhelming brightness.
Is it recommended? It is highly recommended for those who prioritize comfort during use and enjoy a mixed playlist. The fitting is very comfortable, it's lightweight, the cable is flexible, and the inclusion of a volume button is a feature that is very rare in IEMs, even those priced from the hundreds to the millions. Listening to any song—from bass-heavy tracks, vocal-centered music, instrumental pieces, double pedal metal, soft vocals like Raisa or Isyana, to powerful vocals like Ariel Noah and shouting vocals like Taka from One Ok Rock—everything sounds pleasant.
I have also decided not to sell it in the near future; I want to enjoy this IEM for a few more months.
CLOSING
Okay, that's it, friends. That's all for this review of the Truthear Gate. If you liked this review, please give it a like and share it with others who might need a reference. But remember, it all comes back to your personal taste. That's it for this review; we’ll meet again in the next one. Thank you very much.
Review Celest IgniteX Beast | Beautiful, Unique, and Intriguing
Alright, everyone. Don't be surprised if in my recent reviews, especially on YouTube (Alba Project Review), I rarely say things like, "This IEM is not great," "The tuning is terrible," or "This IEM isn't worth it." The reason is that it seems like it's becoming rare to find an IEM with terrible tuning or poor technical performance in recent releases.
The IEM we're discussing today also has an interesting tonality. I’m not sure if it's going to be widely liked, but I personally like it, even though the tuning can be described as unique. Unique but enjoyable, that's how it is.
Aside from the tuning, the build quality of this IEM is also really good, almost like a CIEM or custom in-ear monitor. Yeah, I was a bit annoyed at first when I got hit with a hefty tax charge—almost double, in fact—making the tax more expensive than the Simgot SuperMix4, which costs three times the price of this IEM.
But after unboxing, even before trying the sound, I already liked the design and build quality. And after trying out 3 or 4 songs, I found that I liked the sound too.
So, the hefty tax wasn't so regrettable anymore. You could say it was worth it.
Alright, how interesting is our IEM this time? Let’s dive right into it. This is my review of the Celest IgniteX Beast.
Thanks toAlright, first, I’d like to say thank you to Celest Audio for sending over this sample unit to review. Just a quick disclaimer: even though this is a sent unit, I’m writing this review independently, without any interference from the sender or anyone else.
PriceThe price for the Celest IgniteX Beast is around 750,000 IDR or approximately 49 USD. So, if you find a store selling it at a much higher price, it’s a good idea to check other shops first. There are often online stores that set their prices arbitrarily—some even sell it for over a million IDR, as I checked earlier.
SpecificationsAs for the technical specifications, the IgniteX Beast uses a Dual Driver Hybrid configuration, featuring a 10mm LCP Dynamic Driver, paired with a Balanced Armature.
There are various interface options available: some use USB Type-C with DSP, while others come with a standard 3.5mm single-ended jack. There's also a Type-C version with a detachable microphone, similar to gaming headphones. This time, I had the chance to try the Type-C or DSP version with a built-in microphone.
The sensitivity is 106dB, the impedance is 16 Ohms, and the frequency range is 20Hz to 20KHz.
The connection between the driver and the cable uses the standard 2-pin 0.78mm configuration.
PackagingThe packaging is pretty small, about the same size as KZ's boxes, but it looks interesting because the text is printed in a gold-like ink. So, even though it's simple, it still gives off a luxurious feel. It doesn’t look cheap at all.
On the front, there's no mockup image of the IEM, just the text and a sketch of a dragon head, while on the back, there's a brief overview of the specifications. On the sides, you’ll find additional info like their social media details, and other information.
AccessoriesInside the package, you’ll get two types of eartips, each with three pairs. There are 3 pairs of Widebore eartips, which are gray, and another 3 pairs of standard eartips, which come in yellow, pink, and light blue.
Additionally, there’s the cable, a USB Type-C DSP, and of course, the pair of these beautiful IEM units.
Build QualityIn terms of build quality, this is one of the best, if not the best, in its price range, especially for those who don't like metal IEMs. I’m truly impressed with the housing and faceplate, which use full resin material. And when I say full, I mean it's completely solid inside, not hollow. It does give the impression that there isn’t much acoustic space inside, but we’ll discuss that later when we talk about the sound, especially the soundstage.
What’s clear is that the build quality is excellent for an IEM priced at around 700,000 IDR. The resin is great—very solid, scratch-resistant, and the faceplate is beautiful, plus it doesn’t easily show fingerprints. Overall, it's just fantastic. The 3D-printed resin feels very solid, like a Custom In-Ear Monitor (CIEM).
As for the cable, I think it's fair for the price. It's not a bad cable, but also not exceptionally good. It’s quite similar to the cable of the Truthear Gate, but this one uses a DSP interface. I’m not sure what chip is used for the DAC, though. What’s clear is that it has a DAC, supports USB Exclusive Mode, and offers Bit Perfect in apps like UAPP, Fiio Music, or HiBy Music.
The eartips are also good, though not particularly special. Still, they’re decent, and the included eartips for the others should at least be this good—nothing worse, if possible. They’re soft, have the right amount of elasticity, and I had no complaints while using them.
FittingIn terms of fitting, this IEM feels really comfortable in my ears, even though its shape mimics a CIEM (Custom In-Ear Monitor) with various curves. It fits me very well, though this might not necessarily be the case for everyone. The sound isolation is excellent for me, without causing any discomfort or fatigue. I’ve had no issues wearing it for hours on end during the day. Even after 3 or 4 hours of continuous use during work—like video editing, voice-over editing, and other tasks that require earphones—I found it quite comfortable.
The cable is also comfortable to wear, with the only minor issue being that the earhooks feel a bit loose around my ears. Other than that, such as the microphonic effect and cable flexibility, there are no significant complaints.
Sound Quality
For sound quality, this IEM has a unique tuning, but for those who don’t have high expectations for sparkling treble, it should still be very acceptable.
Low / Bass
Let’s start with the low frequencies or bass. This IEM is a bit difficult to label as neutral, especially if all your previous IEMs have been bass-heavy. The IgniteX Beast has substantial sub-bass that hits deep, is impactful, very tidy, and has decent transient speed. The mid-bass, on the other hand, is just adequate. So, the focus is more on the deep, fast sub-bass. For those who enjoy listening to EDM, the mid-bass might feel lacking here, but when listening through the sub-bass, the depth of the sub-bass in the IgniteX Beast can fill the sound and provide a grand impression. For genres like pop, rock, and dangdut, it performs quite well. Even in terms of transient speed, it can keep up with double pedal sections in metal music, although it's not super agile.
The positioning of the bass is also quite unique; it seems to have a separation that makes the bass hits feel somewhat distinct, placed a bit further apart from the other elements. However, it’s not excessively offside. In terms of imaging, the pinpoint accuracy can feel a bit odd and less natural, but it's still enjoyable. It might not be the best choice if your needs involve monitoring, mixing, and mastering. However, for casual listening, this creates a nice sense of extra separation, distinguishing the bass elements from other layers of instruments. This is similar to what I experienced with the CCA CSN IEM.
Mid & Vocals
Moving on to the mid frequencies and vocal presentation, the Celest IgniteX Beast features a unique vocal positioning. Despite the bass being quite prominent, the vocals are still relatively forward or well-placed. This is a great and unique position for an IEM with substantial bass. Indeed, the bass is notably strong in the sub-bass region, while the mid-bass is lesser, and the lower mids dip down before rising again in the mid to upper mid-range, where the vocals come back up.
For male vocals, the thickness is just adequate; in some songs, heavier male vocals may feel slightly thin. However, for female vocals, the presentation is forward and sufficiently thick, with a pleasing sweetness. The timbre from the balanced armature (BA) drivers in the vocals does not come off too BA-ish. One could say that the vocals of the IgniteX Beast are quite natural for a BA character.
Other instruments in the midrange, like piano and guitar, are also presented naturally, with clear, forward, and precise notes. Everything is showcased very cleanly. This IEM is particularly interesting for those who enjoy vocal-centric music but don’t want to lose much bass. It handles shoutiness and sibilance quite safely, making it a solid choice for various listening preferences.
High / Treble
Moving on to the high frequencies or treble, this IEM is not designed for those who are trebleheads. It has a lower treble that can sound somewhat subdued, especially when listening to the initial strikes of cymbals, which may come off as a bit small and pushed back. The mid-treble is also relatively recessed. However, in the upper treble region, it does deliver a pleasing airiness.
Overall, the treble tuning of the IgniteX Beast should be a good solution for those who are sensitive to treble and dislike the forward treble typically found in Harman tuning. While it maintains a nice airy quality, it isn’t sharp or piercing. The tuning ensures that it’s not overly bright or dark, striking a balance that avoids harshness.
This IEM may not be the best fit for those who are passionate about instrumental music, classical genres, or solo performances featuring instruments like guitar and violin, as the treble might lack the necessary bite and presence for those listening experiences.
TechnicalityIn terms of technical performance, one of the most impressive aspects of this IEM is its resolution, clarity, and imaging. The timbre is quite natural for a hybrid configuration of dynamic driver (DD) and balanced armature (BA), featuring solid resolution with clear and precise transitions between notes. The sound is clean and transparent without any muddiness, despite the overall tuning leaning towards a warm character—albeit a clean warmth.
Imaging is also commendable, providing a sense of space that feels holographic and rounded. The depth is well-defined, and both the height and lateral dimensions are apparent, resembling a small sphere. While it may not deliver a grand or expansive soundstage, it feels more like an intimate concert experience in a moderately sized venue with well-placed sound systems. The soundstage is adequate, enveloping the head with evenly distributed sound, and instrument positioning is clear and distinct.
Regarding detail retrieval, this IEM performs well overall; however, the lower treble and mid-treble regions are somewhat recessed. This can result in a lack of perceived detail for those specifically seeking treble detail.
Conclusion & ComparationIn conclusion, the Celest IgniteX Beast may be an excellent choice for those who want a warm tuning while still enjoying forward, sweet, clean vocals free from shouty or sibilant effects, without losing much bass. This IEM is also suitable for those who are not keen on overly forward treble. Especially for lower treble and mid treble, which can often feel piercing, this IEM is very safe while still providing a pleasant airy quality, making it feel clean and clear despite its warm character.
When compared, its closest competitors are the 7Hz Sonus and the Zhulinniao Qingluan Z4.
With the Sonus, the soundstage is wider and the details are better thanks to its treble tuning. Sonus also includes more eartips and a quality pouch. However, in terms of build quality, the IgniteX is superior, while the Sonus cable is better despite its flat appearance resembling kwetiau. Both have good resolution and clarity, but the IgniteX imaging is slightly better in holographic aspects, while the Sonus feels more majestic. For vocals, the IgniteX offers a more natural timbre that is more comfortable for long listening sessions.
Moving on to the Qingluan Z4, its tuning is more neutral with less bass, but it boasts very fast transient speed, similar to planar IEMs like the KZ PR2 or PR3. The vocals on the Qingluan Z4 are more pronounced, although their sweetness is comparable. The IgniteX provides warmer vocals, and at this moment, I prefer listening to the IgniteX over the Qingluan Z4. For those who enjoy treble, the Qingluan Z4 delivers a more special, sparkling treble with greater detail from lower to upper treble. Its soundstage is also wider like the Sonus, but the 3D sensation is better in the IgniteX. Regarding the package contents, the Qingluan Z4 wins with its many eartips and interchangeable nozzles, although I personally dislike the sound from the second nozzle. The Qingluan Z4 also offers a better cable and a hard case, while the Celest IgniteX only includes the IEM, a cable, and six pairs of eartips.
So, is it worth it? For me, yes, it is worth it. It has a unique tuning that is suitable for my collection, and I enjoy its tuning, even though it is not necessarily my favorite or essential. If the IgniteX had slightly elevated mid treble, I would likely enjoy it even more. I tend to focus on vocal-centric music, and the first thing I notice is the vocal tuning and how the timbre sounds. Fortunately, the Celest IgniteX matches my preferences very well, especially considering its solid build quality and beautiful design. Additionally, this is my first IEM with a DSP jack, so it's also a new experience for me to try out a DSP IEM.
As for you all, I suggest asking yourselves if your preferences align with what I described. If they do, this could be worth purchasing. If my description indicates a mismatch with your tastes, it might be best not to buy it, or at least to try it out first if samples are available, or buy it to test and sell it later if it doesn't suit you. For those who prefer not to use the DSP Type-C, a standard 3.5mm SE version is also available.
Okay, that’s it for our review this time. Overall, I really like it, from its unique tonality, technical aspects, to its build quality and beautiful design.
Like if you enjoyed this discussion, comment below if you have any questions, and we’ll meet again in the next review. Alright, thank you very much.

Review: Simgot SuperMix4 | Even Better as an All-Rounder Favorite
Hi everyone,
Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Alright, first, I’d like to say thank you to Celest Audio for sending over this sample unit to review. Just a quick disclaimer: even though this is a sent unit, I’m writing this review independently, without any interference from the sender or anyone else.
PriceThe price for the Celest IgniteX Beast is around 750,000 IDR or approximately 49 USD. So, if you find a store selling it at a much higher price, it’s a good idea to check other shops first. There are often online stores that set their prices arbitrarily—some even sell it for over a million IDR, as I checked earlier.
SpecificationsAs for the technical specifications, the IgniteX Beast uses a Dual Driver Hybrid configuration, featuring a 10mm LCP Dynamic Driver, paired with a Balanced Armature.
There are various interface options available: some use USB Type-C with DSP, while others come with a standard 3.5mm single-ended jack. There's also a Type-C version with a detachable microphone, similar to gaming headphones. This time, I had the chance to try the Type-C or DSP version with a built-in microphone.
The sensitivity is 106dB, the impedance is 16 Ohms, and the frequency range is 20Hz to 20KHz.
The connection between the driver and the cable uses the standard 2-pin 0.78mm configuration.
PackagingThe packaging is pretty small, about the same size as KZ's boxes, but it looks interesting because the text is printed in a gold-like ink. So, even though it's simple, it still gives off a luxurious feel. It doesn’t look cheap at all.
On the front, there's no mockup image of the IEM, just the text and a sketch of a dragon head, while on the back, there's a brief overview of the specifications. On the sides, you’ll find additional info like their social media details, and other information.
AccessoriesInside the package, you’ll get two types of eartips, each with three pairs. There are 3 pairs of Widebore eartips, which are gray, and another 3 pairs of standard eartips, which come in yellow, pink, and light blue.
Additionally, there’s the cable, a USB Type-C DSP, and of course, the pair of these beautiful IEM units.
Build QualityIn terms of build quality, this is one of the best, if not the best, in its price range, especially for those who don't like metal IEMs. I’m truly impressed with the housing and faceplate, which use full resin material. And when I say full, I mean it's completely solid inside, not hollow. It does give the impression that there isn’t much acoustic space inside, but we’ll discuss that later when we talk about the sound, especially the soundstage.
What’s clear is that the build quality is excellent for an IEM priced at around 700,000 IDR. The resin is great—very solid, scratch-resistant, and the faceplate is beautiful, plus it doesn’t easily show fingerprints. Overall, it's just fantastic. The 3D-printed resin feels very solid, like a Custom In-Ear Monitor (CIEM).
As for the cable, I think it's fair for the price. It's not a bad cable, but also not exceptionally good. It’s quite similar to the cable of the Truthear Gate, but this one uses a DSP interface. I’m not sure what chip is used for the DAC, though. What’s clear is that it has a DAC, supports USB Exclusive Mode, and offers Bit Perfect in apps like UAPP, Fiio Music, or HiBy Music.
The eartips are also good, though not particularly special. Still, they’re decent, and the included eartips for the others should at least be this good—nothing worse, if possible. They’re soft, have the right amount of elasticity, and I had no complaints while using them.
FittingIn terms of fitting, this IEM feels really comfortable in my ears, even though its shape mimics a CIEM (Custom In-Ear Monitor) with various curves. It fits me very well, though this might not necessarily be the case for everyone. The sound isolation is excellent for me, without causing any discomfort or fatigue. I’ve had no issues wearing it for hours on end during the day. Even after 3 or 4 hours of continuous use during work—like video editing, voice-over editing, and other tasks that require earphones—I found it quite comfortable.
The cable is also comfortable to wear, with the only minor issue being that the earhooks feel a bit loose around my ears. Other than that, such as the microphonic effect and cable flexibility, there are no significant complaints.
Sound Quality
For sound quality, this IEM has a unique tuning, but for those who don’t have high expectations for sparkling treble, it should still be very acceptable.
Low / Bass
Let’s start with the low frequencies or bass. This IEM is a bit difficult to label as neutral, especially if all your previous IEMs have been bass-heavy. The IgniteX Beast has substantial sub-bass that hits deep, is impactful, very tidy, and has decent transient speed. The mid-bass, on the other hand, is just adequate. So, the focus is more on the deep, fast sub-bass. For those who enjoy listening to EDM, the mid-bass might feel lacking here, but when listening through the sub-bass, the depth of the sub-bass in the IgniteX Beast can fill the sound and provide a grand impression. For genres like pop, rock, and dangdut, it performs quite well. Even in terms of transient speed, it can keep up with double pedal sections in metal music, although it's not super agile.
The positioning of the bass is also quite unique; it seems to have a separation that makes the bass hits feel somewhat distinct, placed a bit further apart from the other elements. However, it’s not excessively offside. In terms of imaging, the pinpoint accuracy can feel a bit odd and less natural, but it's still enjoyable. It might not be the best choice if your needs involve monitoring, mixing, and mastering. However, for casual listening, this creates a nice sense of extra separation, distinguishing the bass elements from other layers of instruments. This is similar to what I experienced with the CCA CSN IEM.
Mid & Vocals
Moving on to the mid frequencies and vocal presentation, the Celest IgniteX Beast features a unique vocal positioning. Despite the bass being quite prominent, the vocals are still relatively forward or well-placed. This is a great and unique position for an IEM with substantial bass. Indeed, the bass is notably strong in the sub-bass region, while the mid-bass is lesser, and the lower mids dip down before rising again in the mid to upper mid-range, where the vocals come back up.
For male vocals, the thickness is just adequate; in some songs, heavier male vocals may feel slightly thin. However, for female vocals, the presentation is forward and sufficiently thick, with a pleasing sweetness. The timbre from the balanced armature (BA) drivers in the vocals does not come off too BA-ish. One could say that the vocals of the IgniteX Beast are quite natural for a BA character.
Other instruments in the midrange, like piano and guitar, are also presented naturally, with clear, forward, and precise notes. Everything is showcased very cleanly. This IEM is particularly interesting for those who enjoy vocal-centric music but don’t want to lose much bass. It handles shoutiness and sibilance quite safely, making it a solid choice for various listening preferences.
High / Treble
Moving on to the high frequencies or treble, this IEM is not designed for those who are trebleheads. It has a lower treble that can sound somewhat subdued, especially when listening to the initial strikes of cymbals, which may come off as a bit small and pushed back. The mid-treble is also relatively recessed. However, in the upper treble region, it does deliver a pleasing airiness.
Overall, the treble tuning of the IgniteX Beast should be a good solution for those who are sensitive to treble and dislike the forward treble typically found in Harman tuning. While it maintains a nice airy quality, it isn’t sharp or piercing. The tuning ensures that it’s not overly bright or dark, striking a balance that avoids harshness.
This IEM may not be the best fit for those who are passionate about instrumental music, classical genres, or solo performances featuring instruments like guitar and violin, as the treble might lack the necessary bite and presence for those listening experiences.
TechnicalityIn terms of technical performance, one of the most impressive aspects of this IEM is its resolution, clarity, and imaging. The timbre is quite natural for a hybrid configuration of dynamic driver (DD) and balanced armature (BA), featuring solid resolution with clear and precise transitions between notes. The sound is clean and transparent without any muddiness, despite the overall tuning leaning towards a warm character—albeit a clean warmth.
Imaging is also commendable, providing a sense of space that feels holographic and rounded. The depth is well-defined, and both the height and lateral dimensions are apparent, resembling a small sphere. While it may not deliver a grand or expansive soundstage, it feels more like an intimate concert experience in a moderately sized venue with well-placed sound systems. The soundstage is adequate, enveloping the head with evenly distributed sound, and instrument positioning is clear and distinct.
Regarding detail retrieval, this IEM performs well overall; however, the lower treble and mid-treble regions are somewhat recessed. This can result in a lack of perceived detail for those specifically seeking treble detail.
Conclusion & ComparationIn conclusion, the Celest IgniteX Beast may be an excellent choice for those who want a warm tuning while still enjoying forward, sweet, clean vocals free from shouty or sibilant effects, without losing much bass. This IEM is also suitable for those who are not keen on overly forward treble. Especially for lower treble and mid treble, which can often feel piercing, this IEM is very safe while still providing a pleasant airy quality, making it feel clean and clear despite its warm character.
When compared, its closest competitors are the 7Hz Sonus and the Zhulinniao Qingluan Z4.
With the Sonus, the soundstage is wider and the details are better thanks to its treble tuning. Sonus also includes more eartips and a quality pouch. However, in terms of build quality, the IgniteX is superior, while the Sonus cable is better despite its flat appearance resembling kwetiau. Both have good resolution and clarity, but the IgniteX imaging is slightly better in holographic aspects, while the Sonus feels more majestic. For vocals, the IgniteX offers a more natural timbre that is more comfortable for long listening sessions.
Moving on to the Qingluan Z4, its tuning is more neutral with less bass, but it boasts very fast transient speed, similar to planar IEMs like the KZ PR2 or PR3. The vocals on the Qingluan Z4 are more pronounced, although their sweetness is comparable. The IgniteX provides warmer vocals, and at this moment, I prefer listening to the IgniteX over the Qingluan Z4. For those who enjoy treble, the Qingluan Z4 delivers a more special, sparkling treble with greater detail from lower to upper treble. Its soundstage is also wider like the Sonus, but the 3D sensation is better in the IgniteX. Regarding the package contents, the Qingluan Z4 wins with its many eartips and interchangeable nozzles, although I personally dislike the sound from the second nozzle. The Qingluan Z4 also offers a better cable and a hard case, while the Celest IgniteX only includes the IEM, a cable, and six pairs of eartips.
So, is it worth it? For me, yes, it is worth it. It has a unique tuning that is suitable for my collection, and I enjoy its tuning, even though it is not necessarily my favorite or essential. If the IgniteX had slightly elevated mid treble, I would likely enjoy it even more. I tend to focus on vocal-centric music, and the first thing I notice is the vocal tuning and how the timbre sounds. Fortunately, the Celest IgniteX matches my preferences very well, especially considering its solid build quality and beautiful design. Additionally, this is my first IEM with a DSP jack, so it's also a new experience for me to try out a DSP IEM.
As for you all, I suggest asking yourselves if your preferences align with what I described. If they do, this could be worth purchasing. If my description indicates a mismatch with your tastes, it might be best not to buy it, or at least to try it out first if samples are available, or buy it to test and sell it later if it doesn't suit you. For those who prefer not to use the DSP Type-C, a standard 3.5mm SE version is also available.
Okay, that’s it for our review this time. Overall, I really like it, from its unique tonality, technical aspects, to its build quality and beautiful design.
Like if you enjoyed this discussion, comment below if you have any questions, and we’ll meet again in the next review. Alright, thank you very much.

Review: Simgot SuperMix4 | Even Better as an All-Rounder Favorite
Hi everyone,
Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The price for the Celest IgniteX Beast is around 750,000 IDR or approximately 49 USD. So, if you find a store selling it at a much higher price, it’s a good idea to check other shops first. There are often online stores that set their prices arbitrarily—some even sell it for over a million IDR, as I checked earlier.
SpecificationsAs for the technical specifications, the IgniteX Beast uses a Dual Driver Hybrid configuration, featuring a 10mm LCP Dynamic Driver, paired with a Balanced Armature.
There are various interface options available: some use USB Type-C with DSP, while others come with a standard 3.5mm single-ended jack. There's also a Type-C version with a detachable microphone, similar to gaming headphones. This time, I had the chance to try the Type-C or DSP version with a built-in microphone.
The sensitivity is 106dB, the impedance is 16 Ohms, and the frequency range is 20Hz to 20KHz.
The connection between the driver and the cable uses the standard 2-pin 0.78mm configuration.
PackagingThe packaging is pretty small, about the same size as KZ's boxes, but it looks interesting because the text is printed in a gold-like ink. So, even though it's simple, it still gives off a luxurious feel. It doesn’t look cheap at all.
On the front, there's no mockup image of the IEM, just the text and a sketch of a dragon head, while on the back, there's a brief overview of the specifications. On the sides, you’ll find additional info like their social media details, and other information.
AccessoriesInside the package, you’ll get two types of eartips, each with three pairs. There are 3 pairs of Widebore eartips, which are gray, and another 3 pairs of standard eartips, which come in yellow, pink, and light blue.
Additionally, there’s the cable, a USB Type-C DSP, and of course, the pair of these beautiful IEM units.
Build QualityIn terms of build quality, this is one of the best, if not the best, in its price range, especially for those who don't like metal IEMs. I’m truly impressed with the housing and faceplate, which use full resin material. And when I say full, I mean it's completely solid inside, not hollow. It does give the impression that there isn’t much acoustic space inside, but we’ll discuss that later when we talk about the sound, especially the soundstage.
What’s clear is that the build quality is excellent for an IEM priced at around 700,000 IDR. The resin is great—very solid, scratch-resistant, and the faceplate is beautiful, plus it doesn’t easily show fingerprints. Overall, it's just fantastic. The 3D-printed resin feels very solid, like a Custom In-Ear Monitor (CIEM).
As for the cable, I think it's fair for the price. It's not a bad cable, but also not exceptionally good. It’s quite similar to the cable of the Truthear Gate, but this one uses a DSP interface. I’m not sure what chip is used for the DAC, though. What’s clear is that it has a DAC, supports USB Exclusive Mode, and offers Bit Perfect in apps like UAPP, Fiio Music, or HiBy Music.
The eartips are also good, though not particularly special. Still, they’re decent, and the included eartips for the others should at least be this good—nothing worse, if possible. They’re soft, have the right amount of elasticity, and I had no complaints while using them.
FittingIn terms of fitting, this IEM feels really comfortable in my ears, even though its shape mimics a CIEM (Custom In-Ear Monitor) with various curves. It fits me very well, though this might not necessarily be the case for everyone. The sound isolation is excellent for me, without causing any discomfort or fatigue. I’ve had no issues wearing it for hours on end during the day. Even after 3 or 4 hours of continuous use during work—like video editing, voice-over editing, and other tasks that require earphones—I found it quite comfortable.
The cable is also comfortable to wear, with the only minor issue being that the earhooks feel a bit loose around my ears. Other than that, such as the microphonic effect and cable flexibility, there are no significant complaints.
Sound Quality
For sound quality, this IEM has a unique tuning, but for those who don’t have high expectations for sparkling treble, it should still be very acceptable.
Low / Bass
Let’s start with the low frequencies or bass. This IEM is a bit difficult to label as neutral, especially if all your previous IEMs have been bass-heavy. The IgniteX Beast has substantial sub-bass that hits deep, is impactful, very tidy, and has decent transient speed. The mid-bass, on the other hand, is just adequate. So, the focus is more on the deep, fast sub-bass. For those who enjoy listening to EDM, the mid-bass might feel lacking here, but when listening through the sub-bass, the depth of the sub-bass in the IgniteX Beast can fill the sound and provide a grand impression. For genres like pop, rock, and dangdut, it performs quite well. Even in terms of transient speed, it can keep up with double pedal sections in metal music, although it's not super agile.
The positioning of the bass is also quite unique; it seems to have a separation that makes the bass hits feel somewhat distinct, placed a bit further apart from the other elements. However, it’s not excessively offside. In terms of imaging, the pinpoint accuracy can feel a bit odd and less natural, but it's still enjoyable. It might not be the best choice if your needs involve monitoring, mixing, and mastering. However, for casual listening, this creates a nice sense of extra separation, distinguishing the bass elements from other layers of instruments. This is similar to what I experienced with the CCA CSN IEM.
Mid & Vocals
Moving on to the mid frequencies and vocal presentation, the Celest IgniteX Beast features a unique vocal positioning. Despite the bass being quite prominent, the vocals are still relatively forward or well-placed. This is a great and unique position for an IEM with substantial bass. Indeed, the bass is notably strong in the sub-bass region, while the mid-bass is lesser, and the lower mids dip down before rising again in the mid to upper mid-range, where the vocals come back up.
For male vocals, the thickness is just adequate; in some songs, heavier male vocals may feel slightly thin. However, for female vocals, the presentation is forward and sufficiently thick, with a pleasing sweetness. The timbre from the balanced armature (BA) drivers in the vocals does not come off too BA-ish. One could say that the vocals of the IgniteX Beast are quite natural for a BA character.
Other instruments in the midrange, like piano and guitar, are also presented naturally, with clear, forward, and precise notes. Everything is showcased very cleanly. This IEM is particularly interesting for those who enjoy vocal-centric music but don’t want to lose much bass. It handles shoutiness and sibilance quite safely, making it a solid choice for various listening preferences.
High / Treble
Moving on to the high frequencies or treble, this IEM is not designed for those who are trebleheads. It has a lower treble that can sound somewhat subdued, especially when listening to the initial strikes of cymbals, which may come off as a bit small and pushed back. The mid-treble is also relatively recessed. However, in the upper treble region, it does deliver a pleasing airiness.
Overall, the treble tuning of the IgniteX Beast should be a good solution for those who are sensitive to treble and dislike the forward treble typically found in Harman tuning. While it maintains a nice airy quality, it isn’t sharp or piercing. The tuning ensures that it’s not overly bright or dark, striking a balance that avoids harshness.
This IEM may not be the best fit for those who are passionate about instrumental music, classical genres, or solo performances featuring instruments like guitar and violin, as the treble might lack the necessary bite and presence for those listening experiences.
TechnicalityIn terms of technical performance, one of the most impressive aspects of this IEM is its resolution, clarity, and imaging. The timbre is quite natural for a hybrid configuration of dynamic driver (DD) and balanced armature (BA), featuring solid resolution with clear and precise transitions between notes. The sound is clean and transparent without any muddiness, despite the overall tuning leaning towards a warm character—albeit a clean warmth.
Imaging is also commendable, providing a sense of space that feels holographic and rounded. The depth is well-defined, and both the height and lateral dimensions are apparent, resembling a small sphere. While it may not deliver a grand or expansive soundstage, it feels more like an intimate concert experience in a moderately sized venue with well-placed sound systems. The soundstage is adequate, enveloping the head with evenly distributed sound, and instrument positioning is clear and distinct.
Regarding detail retrieval, this IEM performs well overall; however, the lower treble and mid-treble regions are somewhat recessed. This can result in a lack of perceived detail for those specifically seeking treble detail.
Conclusion & ComparationIn conclusion, the Celest IgniteX Beast may be an excellent choice for those who want a warm tuning while still enjoying forward, sweet, clean vocals free from shouty or sibilant effects, without losing much bass. This IEM is also suitable for those who are not keen on overly forward treble. Especially for lower treble and mid treble, which can often feel piercing, this IEM is very safe while still providing a pleasant airy quality, making it feel clean and clear despite its warm character.
When compared, its closest competitors are the 7Hz Sonus and the Zhulinniao Qingluan Z4.
With the Sonus, the soundstage is wider and the details are better thanks to its treble tuning. Sonus also includes more eartips and a quality pouch. However, in terms of build quality, the IgniteX is superior, while the Sonus cable is better despite its flat appearance resembling kwetiau. Both have good resolution and clarity, but the IgniteX imaging is slightly better in holographic aspects, while the Sonus feels more majestic. For vocals, the IgniteX offers a more natural timbre that is more comfortable for long listening sessions.
Moving on to the Qingluan Z4, its tuning is more neutral with less bass, but it boasts very fast transient speed, similar to planar IEMs like the KZ PR2 or PR3. The vocals on the Qingluan Z4 are more pronounced, although their sweetness is comparable. The IgniteX provides warmer vocals, and at this moment, I prefer listening to the IgniteX over the Qingluan Z4. For those who enjoy treble, the Qingluan Z4 delivers a more special, sparkling treble with greater detail from lower to upper treble. Its soundstage is also wider like the Sonus, but the 3D sensation is better in the IgniteX. Regarding the package contents, the Qingluan Z4 wins with its many eartips and interchangeable nozzles, although I personally dislike the sound from the second nozzle. The Qingluan Z4 also offers a better cable and a hard case, while the Celest IgniteX only includes the IEM, a cable, and six pairs of eartips.
So, is it worth it? For me, yes, it is worth it. It has a unique tuning that is suitable for my collection, and I enjoy its tuning, even though it is not necessarily my favorite or essential. If the IgniteX had slightly elevated mid treble, I would likely enjoy it even more. I tend to focus on vocal-centric music, and the first thing I notice is the vocal tuning and how the timbre sounds. Fortunately, the Celest IgniteX matches my preferences very well, especially considering its solid build quality and beautiful design. Additionally, this is my first IEM with a DSP jack, so it's also a new experience for me to try out a DSP IEM.
As for you all, I suggest asking yourselves if your preferences align with what I described. If they do, this could be worth purchasing. If my description indicates a mismatch with your tastes, it might be best not to buy it, or at least to try it out first if samples are available, or buy it to test and sell it later if it doesn't suit you. For those who prefer not to use the DSP Type-C, a standard 3.5mm SE version is also available.
Okay, that’s it for our review this time. Overall, I really like it, from its unique tonality, technical aspects, to its build quality and beautiful design.
Like if you enjoyed this discussion, comment below if you have any questions, and we’ll meet again in the next review. Alright, thank you very much.

Review: Simgot SuperMix4 | Even Better as an All-Rounder Favorite
Hi everyone,
Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear

Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM | I Choose You
Pros: + The availability of 3 nozzle options for tuning
+ Its sound presentation is very clean and clear
+ Good bass texture
+ Clean vocal presentation with clear articulation
+ Decent sound staging and imaging
Cons: - Some may find the vocals thin
- Average instrument separation, but not bad either
- Lack of airiness
Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

New Head-Fier
Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

As for the technical specifications, the IgniteX Beast uses a Dual Driver Hybrid configuration, featuring a 10mm LCP Dynamic Driver, paired with a Balanced Armature.
There are various interface options available: some use USB Type-C with DSP, while others come with a standard 3.5mm single-ended jack. There's also a Type-C version with a detachable microphone, similar to gaming headphones. This time, I had the chance to try the Type-C or DSP version with a built-in microphone.
The sensitivity is 106dB, the impedance is 16 Ohms, and the frequency range is 20Hz to 20KHz.
The connection between the driver and the cable uses the standard 2-pin 0.78mm configuration.

The connection between the driver and the cable uses the standard 2-pin 0.78mm configuration.
PackagingThe packaging is pretty small, about the same size as KZ's boxes, but it looks interesting because the text is printed in a gold-like ink. So, even though it's simple, it still gives off a luxurious feel. It doesn’t look cheap at all.
On the front, there's no mockup image of the IEM, just the text and a sketch of a dragon head, while on the back, there's a brief overview of the specifications. On the sides, you’ll find additional info like their social media details, and other information.
AccessoriesInside the package, you’ll get two types of eartips, each with three pairs. There are 3 pairs of Widebore eartips, which are gray, and another 3 pairs of standard eartips, which come in yellow, pink, and light blue.
Additionally, there’s the cable, a USB Type-C DSP, and of course, the pair of these beautiful IEM units.
Build QualityIn terms of build quality, this is one of the best, if not the best, in its price range, especially for those who don't like metal IEMs. I’m truly impressed with the housing and faceplate, which use full resin material. And when I say full, I mean it's completely solid inside, not hollow. It does give the impression that there isn’t much acoustic space inside, but we’ll discuss that later when we talk about the sound, especially the soundstage.
What’s clear is that the build quality is excellent for an IEM priced at around 700,000 IDR. The resin is great—very solid, scratch-resistant, and the faceplate is beautiful, plus it doesn’t easily show fingerprints. Overall, it's just fantastic. The 3D-printed resin feels very solid, like a Custom In-Ear Monitor (CIEM).
As for the cable, I think it's fair for the price. It's not a bad cable, but also not exceptionally good. It’s quite similar to the cable of the Truthear Gate, but this one uses a DSP interface. I’m not sure what chip is used for the DAC, though. What’s clear is that it has a DAC, supports USB Exclusive Mode, and offers Bit Perfect in apps like UAPP, Fiio Music, or HiBy Music.
The eartips are also good, though not particularly special. Still, they’re decent, and the included eartips for the others should at least be this good—nothing worse, if possible. They’re soft, have the right amount of elasticity, and I had no complaints while using them.
FittingIn terms of fitting, this IEM feels really comfortable in my ears, even though its shape mimics a CIEM (Custom In-Ear Monitor) with various curves. It fits me very well, though this might not necessarily be the case for everyone. The sound isolation is excellent for me, without causing any discomfort or fatigue. I’ve had no issues wearing it for hours on end during the day. Even after 3 or 4 hours of continuous use during work—like video editing, voice-over editing, and other tasks that require earphones—I found it quite comfortable.
The cable is also comfortable to wear, with the only minor issue being that the earhooks feel a bit loose around my ears. Other than that, such as the microphonic effect and cable flexibility, there are no significant complaints.
Sound Quality
For sound quality, this IEM has a unique tuning, but for those who don’t have high expectations for sparkling treble, it should still be very acceptable.
Low / Bass
Let’s start with the low frequencies or bass. This IEM is a bit difficult to label as neutral, especially if all your previous IEMs have been bass-heavy. The IgniteX Beast has substantial sub-bass that hits deep, is impactful, very tidy, and has decent transient speed. The mid-bass, on the other hand, is just adequate. So, the focus is more on the deep, fast sub-bass. For those who enjoy listening to EDM, the mid-bass might feel lacking here, but when listening through the sub-bass, the depth of the sub-bass in the IgniteX Beast can fill the sound and provide a grand impression. For genres like pop, rock, and dangdut, it performs quite well. Even in terms of transient speed, it can keep up with double pedal sections in metal music, although it's not super agile.
The positioning of the bass is also quite unique; it seems to have a separation that makes the bass hits feel somewhat distinct, placed a bit further apart from the other elements. However, it’s not excessively offside. In terms of imaging, the pinpoint accuracy can feel a bit odd and less natural, but it's still enjoyable. It might not be the best choice if your needs involve monitoring, mixing, and mastering. However, for casual listening, this creates a nice sense of extra separation, distinguishing the bass elements from other layers of instruments. This is similar to what I experienced with the CCA CSN IEM.
Mid & Vocals
Moving on to the mid frequencies and vocal presentation, the Celest IgniteX Beast features a unique vocal positioning. Despite the bass being quite prominent, the vocals are still relatively forward or well-placed. This is a great and unique position for an IEM with substantial bass. Indeed, the bass is notably strong in the sub-bass region, while the mid-bass is lesser, and the lower mids dip down before rising again in the mid to upper mid-range, where the vocals come back up.
For male vocals, the thickness is just adequate; in some songs, heavier male vocals may feel slightly thin. However, for female vocals, the presentation is forward and sufficiently thick, with a pleasing sweetness. The timbre from the balanced armature (BA) drivers in the vocals does not come off too BA-ish. One could say that the vocals of the IgniteX Beast are quite natural for a BA character.
Other instruments in the midrange, like piano and guitar, are also presented naturally, with clear, forward, and precise notes. Everything is showcased very cleanly. This IEM is particularly interesting for those who enjoy vocal-centric music but don’t want to lose much bass. It handles shoutiness and sibilance quite safely, making it a solid choice for various listening preferences.
High / Treble
Moving on to the high frequencies or treble, this IEM is not designed for those who are trebleheads. It has a lower treble that can sound somewhat subdued, especially when listening to the initial strikes of cymbals, which may come off as a bit small and pushed back. The mid-treble is also relatively recessed. However, in the upper treble region, it does deliver a pleasing airiness.
Overall, the treble tuning of the IgniteX Beast should be a good solution for those who are sensitive to treble and dislike the forward treble typically found in Harman tuning. While it maintains a nice airy quality, it isn’t sharp or piercing. The tuning ensures that it’s not overly bright or dark, striking a balance that avoids harshness.
This IEM may not be the best fit for those who are passionate about instrumental music, classical genres, or solo performances featuring instruments like guitar and violin, as the treble might lack the necessary bite and presence for those listening experiences.
TechnicalityIn terms of technical performance, one of the most impressive aspects of this IEM is its resolution, clarity, and imaging. The timbre is quite natural for a hybrid configuration of dynamic driver (DD) and balanced armature (BA), featuring solid resolution with clear and precise transitions between notes. The sound is clean and transparent without any muddiness, despite the overall tuning leaning towards a warm character—albeit a clean warmth.
Imaging is also commendable, providing a sense of space that feels holographic and rounded. The depth is well-defined, and both the height and lateral dimensions are apparent, resembling a small sphere. While it may not deliver a grand or expansive soundstage, it feels more like an intimate concert experience in a moderately sized venue with well-placed sound systems. The soundstage is adequate, enveloping the head with evenly distributed sound, and instrument positioning is clear and distinct.
Regarding detail retrieval, this IEM performs well overall; however, the lower treble and mid-treble regions are somewhat recessed. This can result in a lack of perceived detail for those specifically seeking treble detail.
Conclusion & ComparationIn conclusion, the Celest IgniteX Beast may be an excellent choice for those who want a warm tuning while still enjoying forward, sweet, clean vocals free from shouty or sibilant effects, without losing much bass. This IEM is also suitable for those who are not keen on overly forward treble. Especially for lower treble and mid treble, which can often feel piercing, this IEM is very safe while still providing a pleasant airy quality, making it feel clean and clear despite its warm character.
When compared, its closest competitors are the 7Hz Sonus and the Zhulinniao Qingluan Z4.
With the Sonus, the soundstage is wider and the details are better thanks to its treble tuning. Sonus also includes more eartips and a quality pouch. However, in terms of build quality, the IgniteX is superior, while the Sonus cable is better despite its flat appearance resembling kwetiau. Both have good resolution and clarity, but the IgniteX imaging is slightly better in holographic aspects, while the Sonus feels more majestic. For vocals, the IgniteX offers a more natural timbre that is more comfortable for long listening sessions.
Moving on to the Qingluan Z4, its tuning is more neutral with less bass, but it boasts very fast transient speed, similar to planar IEMs like the KZ PR2 or PR3. The vocals on the Qingluan Z4 are more pronounced, although their sweetness is comparable. The IgniteX provides warmer vocals, and at this moment, I prefer listening to the IgniteX over the Qingluan Z4. For those who enjoy treble, the Qingluan Z4 delivers a more special, sparkling treble with greater detail from lower to upper treble. Its soundstage is also wider like the Sonus, but the 3D sensation is better in the IgniteX. Regarding the package contents, the Qingluan Z4 wins with its many eartips and interchangeable nozzles, although I personally dislike the sound from the second nozzle. The Qingluan Z4 also offers a better cable and a hard case, while the Celest IgniteX only includes the IEM, a cable, and six pairs of eartips.
So, is it worth it? For me, yes, it is worth it. It has a unique tuning that is suitable for my collection, and I enjoy its tuning, even though it is not necessarily my favorite or essential. If the IgniteX had slightly elevated mid treble, I would likely enjoy it even more. I tend to focus on vocal-centric music, and the first thing I notice is the vocal tuning and how the timbre sounds. Fortunately, the Celest IgniteX matches my preferences very well, especially considering its solid build quality and beautiful design. Additionally, this is my first IEM with a DSP jack, so it's also a new experience for me to try out a DSP IEM.
As for you all, I suggest asking yourselves if your preferences align with what I described. If they do, this could be worth purchasing. If my description indicates a mismatch with your tastes, it might be best not to buy it, or at least to try it out first if samples are available, or buy it to test and sell it later if it doesn't suit you. For those who prefer not to use the DSP Type-C, a standard 3.5mm SE version is also available.
Okay, that’s it for our review this time. Overall, I really like it, from its unique tonality, technical aspects, to its build quality and beautiful design.
Like if you enjoyed this discussion, comment below if you have any questions, and we’ll meet again in the next review. Alright, thank you very much.

Review: Simgot SuperMix4 | Even Better as an All-Rounder Favorite
Hi everyone,
Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

New Head-Fier
Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The packaging is pretty small, about the same size as KZ's boxes, but it looks interesting because the text is printed in a gold-like ink. So, even though it's simple, it still gives off a luxurious feel. It doesn’t look cheap at all.
On the front, there's no mockup image of the IEM, just the text and a sketch of a dragon head, while on the back, there's a brief overview of the specifications. On the sides, you’ll find additional info like their social media details, and other information.
On the front, there's no mockup image of the IEM, just the text and a sketch of a dragon head, while on the back, there's a brief overview of the specifications. On the sides, you’ll find additional info like their social media details, and other information.
AccessoriesInside the package, you’ll get two types of eartips, each with three pairs. There are 3 pairs of Widebore eartips, which are gray, and another 3 pairs of standard eartips, which come in yellow, pink, and light blue.
Additionally, there’s the cable, a USB Type-C DSP, and of course, the pair of these beautiful IEM units.
Build QualityIn terms of build quality, this is one of the best, if not the best, in its price range, especially for those who don't like metal IEMs. I’m truly impressed with the housing and faceplate, which use full resin material. And when I say full, I mean it's completely solid inside, not hollow. It does give the impression that there isn’t much acoustic space inside, but we’ll discuss that later when we talk about the sound, especially the soundstage.
What’s clear is that the build quality is excellent for an IEM priced at around 700,000 IDR. The resin is great—very solid, scratch-resistant, and the faceplate is beautiful, plus it doesn’t easily show fingerprints. Overall, it's just fantastic. The 3D-printed resin feels very solid, like a Custom In-Ear Monitor (CIEM).
As for the cable, I think it's fair for the price. It's not a bad cable, but also not exceptionally good. It’s quite similar to the cable of the Truthear Gate, but this one uses a DSP interface. I’m not sure what chip is used for the DAC, though. What’s clear is that it has a DAC, supports USB Exclusive Mode, and offers Bit Perfect in apps like UAPP, Fiio Music, or HiBy Music.
The eartips are also good, though not particularly special. Still, they’re decent, and the included eartips for the others should at least be this good—nothing worse, if possible. They’re soft, have the right amount of elasticity, and I had no complaints while using them.
FittingIn terms of fitting, this IEM feels really comfortable in my ears, even though its shape mimics a CIEM (Custom In-Ear Monitor) with various curves. It fits me very well, though this might not necessarily be the case for everyone. The sound isolation is excellent for me, without causing any discomfort or fatigue. I’ve had no issues wearing it for hours on end during the day. Even after 3 or 4 hours of continuous use during work—like video editing, voice-over editing, and other tasks that require earphones—I found it quite comfortable.
The cable is also comfortable to wear, with the only minor issue being that the earhooks feel a bit loose around my ears. Other than that, such as the microphonic effect and cable flexibility, there are no significant complaints.
Sound Quality
For sound quality, this IEM has a unique tuning, but for those who don’t have high expectations for sparkling treble, it should still be very acceptable.
Low / Bass
Let’s start with the low frequencies or bass. This IEM is a bit difficult to label as neutral, especially if all your previous IEMs have been bass-heavy. The IgniteX Beast has substantial sub-bass that hits deep, is impactful, very tidy, and has decent transient speed. The mid-bass, on the other hand, is just adequate. So, the focus is more on the deep, fast sub-bass. For those who enjoy listening to EDM, the mid-bass might feel lacking here, but when listening through the sub-bass, the depth of the sub-bass in the IgniteX Beast can fill the sound and provide a grand impression. For genres like pop, rock, and dangdut, it performs quite well. Even in terms of transient speed, it can keep up with double pedal sections in metal music, although it's not super agile.
The positioning of the bass is also quite unique; it seems to have a separation that makes the bass hits feel somewhat distinct, placed a bit further apart from the other elements. However, it’s not excessively offside. In terms of imaging, the pinpoint accuracy can feel a bit odd and less natural, but it's still enjoyable. It might not be the best choice if your needs involve monitoring, mixing, and mastering. However, for casual listening, this creates a nice sense of extra separation, distinguishing the bass elements from other layers of instruments. This is similar to what I experienced with the CCA CSN IEM.
Mid & Vocals
Moving on to the mid frequencies and vocal presentation, the Celest IgniteX Beast features a unique vocal positioning. Despite the bass being quite prominent, the vocals are still relatively forward or well-placed. This is a great and unique position for an IEM with substantial bass. Indeed, the bass is notably strong in the sub-bass region, while the mid-bass is lesser, and the lower mids dip down before rising again in the mid to upper mid-range, where the vocals come back up.
For male vocals, the thickness is just adequate; in some songs, heavier male vocals may feel slightly thin. However, for female vocals, the presentation is forward and sufficiently thick, with a pleasing sweetness. The timbre from the balanced armature (BA) drivers in the vocals does not come off too BA-ish. One could say that the vocals of the IgniteX Beast are quite natural for a BA character.
Other instruments in the midrange, like piano and guitar, are also presented naturally, with clear, forward, and precise notes. Everything is showcased very cleanly. This IEM is particularly interesting for those who enjoy vocal-centric music but don’t want to lose much bass. It handles shoutiness and sibilance quite safely, making it a solid choice for various listening preferences.
High / Treble
Moving on to the high frequencies or treble, this IEM is not designed for those who are trebleheads. It has a lower treble that can sound somewhat subdued, especially when listening to the initial strikes of cymbals, which may come off as a bit small and pushed back. The mid-treble is also relatively recessed. However, in the upper treble region, it does deliver a pleasing airiness.
Overall, the treble tuning of the IgniteX Beast should be a good solution for those who are sensitive to treble and dislike the forward treble typically found in Harman tuning. While it maintains a nice airy quality, it isn’t sharp or piercing. The tuning ensures that it’s not overly bright or dark, striking a balance that avoids harshness.
This IEM may not be the best fit for those who are passionate about instrumental music, classical genres, or solo performances featuring instruments like guitar and violin, as the treble might lack the necessary bite and presence for those listening experiences.
TechnicalityIn terms of technical performance, one of the most impressive aspects of this IEM is its resolution, clarity, and imaging. The timbre is quite natural for a hybrid configuration of dynamic driver (DD) and balanced armature (BA), featuring solid resolution with clear and precise transitions between notes. The sound is clean and transparent without any muddiness, despite the overall tuning leaning towards a warm character—albeit a clean warmth.
Imaging is also commendable, providing a sense of space that feels holographic and rounded. The depth is well-defined, and both the height and lateral dimensions are apparent, resembling a small sphere. While it may not deliver a grand or expansive soundstage, it feels more like an intimate concert experience in a moderately sized venue with well-placed sound systems. The soundstage is adequate, enveloping the head with evenly distributed sound, and instrument positioning is clear and distinct.
Regarding detail retrieval, this IEM performs well overall; however, the lower treble and mid-treble regions are somewhat recessed. This can result in a lack of perceived detail for those specifically seeking treble detail.
Conclusion & ComparationIn conclusion, the Celest IgniteX Beast may be an excellent choice for those who want a warm tuning while still enjoying forward, sweet, clean vocals free from shouty or sibilant effects, without losing much bass. This IEM is also suitable for those who are not keen on overly forward treble. Especially for lower treble and mid treble, which can often feel piercing, this IEM is very safe while still providing a pleasant airy quality, making it feel clean and clear despite its warm character.
When compared, its closest competitors are the 7Hz Sonus and the Zhulinniao Qingluan Z4.
With the Sonus, the soundstage is wider and the details are better thanks to its treble tuning. Sonus also includes more eartips and a quality pouch. However, in terms of build quality, the IgniteX is superior, while the Sonus cable is better despite its flat appearance resembling kwetiau. Both have good resolution and clarity, but the IgniteX imaging is slightly better in holographic aspects, while the Sonus feels more majestic. For vocals, the IgniteX offers a more natural timbre that is more comfortable for long listening sessions.
Moving on to the Qingluan Z4, its tuning is more neutral with less bass, but it boasts very fast transient speed, similar to planar IEMs like the KZ PR2 or PR3. The vocals on the Qingluan Z4 are more pronounced, although their sweetness is comparable. The IgniteX provides warmer vocals, and at this moment, I prefer listening to the IgniteX over the Qingluan Z4. For those who enjoy treble, the Qingluan Z4 delivers a more special, sparkling treble with greater detail from lower to upper treble. Its soundstage is also wider like the Sonus, but the 3D sensation is better in the IgniteX. Regarding the package contents, the Qingluan Z4 wins with its many eartips and interchangeable nozzles, although I personally dislike the sound from the second nozzle. The Qingluan Z4 also offers a better cable and a hard case, while the Celest IgniteX only includes the IEM, a cable, and six pairs of eartips.
So, is it worth it? For me, yes, it is worth it. It has a unique tuning that is suitable for my collection, and I enjoy its tuning, even though it is not necessarily my favorite or essential. If the IgniteX had slightly elevated mid treble, I would likely enjoy it even more. I tend to focus on vocal-centric music, and the first thing I notice is the vocal tuning and how the timbre sounds. Fortunately, the Celest IgniteX matches my preferences very well, especially considering its solid build quality and beautiful design. Additionally, this is my first IEM with a DSP jack, so it's also a new experience for me to try out a DSP IEM.
As for you all, I suggest asking yourselves if your preferences align with what I described. If they do, this could be worth purchasing. If my description indicates a mismatch with your tastes, it might be best not to buy it, or at least to try it out first if samples are available, or buy it to test and sell it later if it doesn't suit you. For those who prefer not to use the DSP Type-C, a standard 3.5mm SE version is also available.
Okay, that’s it for our review this time. Overall, I really like it, from its unique tonality, technical aspects, to its build quality and beautiful design.
Like if you enjoyed this discussion, comment below if you have any questions, and we’ll meet again in the next review. Alright, thank you very much.

Review: Simgot SuperMix4 | Even Better as an All-Rounder Favorite
Hi everyone,
Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case

IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.

SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Inside the package, you’ll get two types of eartips, each with three pairs. There are 3 pairs of Widebore eartips, which are gray, and another 3 pairs of standard eartips, which come in yellow, pink, and light blue.
Additionally, there’s the cable, a USB Type-C DSP, and of course, the pair of these beautiful IEM units.
Additionally, there’s the cable, a USB Type-C DSP, and of course, the pair of these beautiful IEM units.
Build QualityIn terms of build quality, this is one of the best, if not the best, in its price range, especially for those who don't like metal IEMs. I’m truly impressed with the housing and faceplate, which use full resin material. And when I say full, I mean it's completely solid inside, not hollow. It does give the impression that there isn’t much acoustic space inside, but we’ll discuss that later when we talk about the sound, especially the soundstage.
What’s clear is that the build quality is excellent for an IEM priced at around 700,000 IDR. The resin is great—very solid, scratch-resistant, and the faceplate is beautiful, plus it doesn’t easily show fingerprints. Overall, it's just fantastic. The 3D-printed resin feels very solid, like a Custom In-Ear Monitor (CIEM).
As for the cable, I think it's fair for the price. It's not a bad cable, but also not exceptionally good. It’s quite similar to the cable of the Truthear Gate, but this one uses a DSP interface. I’m not sure what chip is used for the DAC, though. What’s clear is that it has a DAC, supports USB Exclusive Mode, and offers Bit Perfect in apps like UAPP, Fiio Music, or HiBy Music.
The eartips are also good, though not particularly special. Still, they’re decent, and the included eartips for the others should at least be this good—nothing worse, if possible. They’re soft, have the right amount of elasticity, and I had no complaints while using them.
FittingIn terms of fitting, this IEM feels really comfortable in my ears, even though its shape mimics a CIEM (Custom In-Ear Monitor) with various curves. It fits me very well, though this might not necessarily be the case for everyone. The sound isolation is excellent for me, without causing any discomfort or fatigue. I’ve had no issues wearing it for hours on end during the day. Even after 3 or 4 hours of continuous use during work—like video editing, voice-over editing, and other tasks that require earphones—I found it quite comfortable.
The cable is also comfortable to wear, with the only minor issue being that the earhooks feel a bit loose around my ears. Other than that, such as the microphonic effect and cable flexibility, there are no significant complaints.
Sound Quality
For sound quality, this IEM has a unique tuning, but for those who don’t have high expectations for sparkling treble, it should still be very acceptable.
Low / Bass
Let’s start with the low frequencies or bass. This IEM is a bit difficult to label as neutral, especially if all your previous IEMs have been bass-heavy. The IgniteX Beast has substantial sub-bass that hits deep, is impactful, very tidy, and has decent transient speed. The mid-bass, on the other hand, is just adequate. So, the focus is more on the deep, fast sub-bass. For those who enjoy listening to EDM, the mid-bass might feel lacking here, but when listening through the sub-bass, the depth of the sub-bass in the IgniteX Beast can fill the sound and provide a grand impression. For genres like pop, rock, and dangdut, it performs quite well. Even in terms of transient speed, it can keep up with double pedal sections in metal music, although it's not super agile.
The positioning of the bass is also quite unique; it seems to have a separation that makes the bass hits feel somewhat distinct, placed a bit further apart from the other elements. However, it’s not excessively offside. In terms of imaging, the pinpoint accuracy can feel a bit odd and less natural, but it's still enjoyable. It might not be the best choice if your needs involve monitoring, mixing, and mastering. However, for casual listening, this creates a nice sense of extra separation, distinguishing the bass elements from other layers of instruments. This is similar to what I experienced with the CCA CSN IEM.
Mid & Vocals
Moving on to the mid frequencies and vocal presentation, the Celest IgniteX Beast features a unique vocal positioning. Despite the bass being quite prominent, the vocals are still relatively forward or well-placed. This is a great and unique position for an IEM with substantial bass. Indeed, the bass is notably strong in the sub-bass region, while the mid-bass is lesser, and the lower mids dip down before rising again in the mid to upper mid-range, where the vocals come back up.
For male vocals, the thickness is just adequate; in some songs, heavier male vocals may feel slightly thin. However, for female vocals, the presentation is forward and sufficiently thick, with a pleasing sweetness. The timbre from the balanced armature (BA) drivers in the vocals does not come off too BA-ish. One could say that the vocals of the IgniteX Beast are quite natural for a BA character.
Other instruments in the midrange, like piano and guitar, are also presented naturally, with clear, forward, and precise notes. Everything is showcased very cleanly. This IEM is particularly interesting for those who enjoy vocal-centric music but don’t want to lose much bass. It handles shoutiness and sibilance quite safely, making it a solid choice for various listening preferences.
High / Treble
Moving on to the high frequencies or treble, this IEM is not designed for those who are trebleheads. It has a lower treble that can sound somewhat subdued, especially when listening to the initial strikes of cymbals, which may come off as a bit small and pushed back. The mid-treble is also relatively recessed. However, in the upper treble region, it does deliver a pleasing airiness.
Overall, the treble tuning of the IgniteX Beast should be a good solution for those who are sensitive to treble and dislike the forward treble typically found in Harman tuning. While it maintains a nice airy quality, it isn’t sharp or piercing. The tuning ensures that it’s not overly bright or dark, striking a balance that avoids harshness.
This IEM may not be the best fit for those who are passionate about instrumental music, classical genres, or solo performances featuring instruments like guitar and violin, as the treble might lack the necessary bite and presence for those listening experiences.
TechnicalityIn terms of technical performance, one of the most impressive aspects of this IEM is its resolution, clarity, and imaging. The timbre is quite natural for a hybrid configuration of dynamic driver (DD) and balanced armature (BA), featuring solid resolution with clear and precise transitions between notes. The sound is clean and transparent without any muddiness, despite the overall tuning leaning towards a warm character—albeit a clean warmth.
Imaging is also commendable, providing a sense of space that feels holographic and rounded. The depth is well-defined, and both the height and lateral dimensions are apparent, resembling a small sphere. While it may not deliver a grand or expansive soundstage, it feels more like an intimate concert experience in a moderately sized venue with well-placed sound systems. The soundstage is adequate, enveloping the head with evenly distributed sound, and instrument positioning is clear and distinct.
Regarding detail retrieval, this IEM performs well overall; however, the lower treble and mid-treble regions are somewhat recessed. This can result in a lack of perceived detail for those specifically seeking treble detail.
Conclusion & ComparationIn conclusion, the Celest IgniteX Beast may be an excellent choice for those who want a warm tuning while still enjoying forward, sweet, clean vocals free from shouty or sibilant effects, without losing much bass. This IEM is also suitable for those who are not keen on overly forward treble. Especially for lower treble and mid treble, which can often feel piercing, this IEM is very safe while still providing a pleasant airy quality, making it feel clean and clear despite its warm character.
When compared, its closest competitors are the 7Hz Sonus and the Zhulinniao Qingluan Z4.
With the Sonus, the soundstage is wider and the details are better thanks to its treble tuning. Sonus also includes more eartips and a quality pouch. However, in terms of build quality, the IgniteX is superior, while the Sonus cable is better despite its flat appearance resembling kwetiau. Both have good resolution and clarity, but the IgniteX imaging is slightly better in holographic aspects, while the Sonus feels more majestic. For vocals, the IgniteX offers a more natural timbre that is more comfortable for long listening sessions.
Moving on to the Qingluan Z4, its tuning is more neutral with less bass, but it boasts very fast transient speed, similar to planar IEMs like the KZ PR2 or PR3. The vocals on the Qingluan Z4 are more pronounced, although their sweetness is comparable. The IgniteX provides warmer vocals, and at this moment, I prefer listening to the IgniteX over the Qingluan Z4. For those who enjoy treble, the Qingluan Z4 delivers a more special, sparkling treble with greater detail from lower to upper treble. Its soundstage is also wider like the Sonus, but the 3D sensation is better in the IgniteX. Regarding the package contents, the Qingluan Z4 wins with its many eartips and interchangeable nozzles, although I personally dislike the sound from the second nozzle. The Qingluan Z4 also offers a better cable and a hard case, while the Celest IgniteX only includes the IEM, a cable, and six pairs of eartips.
So, is it worth it? For me, yes, it is worth it. It has a unique tuning that is suitable for my collection, and I enjoy its tuning, even though it is not necessarily my favorite or essential. If the IgniteX had slightly elevated mid treble, I would likely enjoy it even more. I tend to focus on vocal-centric music, and the first thing I notice is the vocal tuning and how the timbre sounds. Fortunately, the Celest IgniteX matches my preferences very well, especially considering its solid build quality and beautiful design. Additionally, this is my first IEM with a DSP jack, so it's also a new experience for me to try out a DSP IEM.
As for you all, I suggest asking yourselves if your preferences align with what I described. If they do, this could be worth purchasing. If my description indicates a mismatch with your tastes, it might be best not to buy it, or at least to try it out first if samples are available, or buy it to test and sell it later if it doesn't suit you. For those who prefer not to use the DSP Type-C, a standard 3.5mm SE version is also available.
Okay, that’s it for our review this time. Overall, I really like it, from its unique tonality, technical aspects, to its build quality and beautiful design.
Like if you enjoyed this discussion, comment below if you have any questions, and we’ll meet again in the next review. Alright, thank you very much.

Review: Simgot SuperMix4 | Even Better as an All-Rounder Favorite
Hi everyone,
Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

In terms of build quality, this is one of the best, if not the best, in its price range, especially for those who don't like metal IEMs. I’m truly impressed with the housing and faceplate, which use full resin material. And when I say full, I mean it's completely solid inside, not hollow. It does give the impression that there isn’t much acoustic space inside, but we’ll discuss that later when we talk about the sound, especially the soundstage.
What’s clear is that the build quality is excellent for an IEM priced at around 700,000 IDR. The resin is great—very solid, scratch-resistant, and the faceplate is beautiful, plus it doesn’t easily show fingerprints. Overall, it's just fantastic. The 3D-printed resin feels very solid, like a Custom In-Ear Monitor (CIEM).
As for the cable, I think it's fair for the price. It's not a bad cable, but also not exceptionally good. It’s quite similar to the cable of the Truthear Gate, but this one uses a DSP interface. I’m not sure what chip is used for the DAC, though. What’s clear is that it has a DAC, supports USB Exclusive Mode, and offers Bit Perfect in apps like UAPP, Fiio Music, or HiBy Music.
The eartips are also good, though not particularly special. Still, they’re decent, and the included eartips for the others should at least be this good—nothing worse, if possible. They’re soft, have the right amount of elasticity, and I had no complaints while using them.

FittingIn terms of fitting, this IEM feels really comfortable in my ears, even though its shape mimics a CIEM (Custom In-Ear Monitor) with various curves. It fits me very well, though this might not necessarily be the case for everyone. The sound isolation is excellent for me, without causing any discomfort or fatigue. I’ve had no issues wearing it for hours on end during the day. Even after 3 or 4 hours of continuous use during work—like video editing, voice-over editing, and other tasks that require earphones—I found it quite comfortable.
The cable is also comfortable to wear, with the only minor issue being that the earhooks feel a bit loose around my ears. Other than that, such as the microphonic effect and cable flexibility, there are no significant complaints.
Sound Quality
For sound quality, this IEM has a unique tuning, but for those who don’t have high expectations for sparkling treble, it should still be very acceptable.
Low / Bass
Let’s start with the low frequencies or bass. This IEM is a bit difficult to label as neutral, especially if all your previous IEMs have been bass-heavy. The IgniteX Beast has substantial sub-bass that hits deep, is impactful, very tidy, and has decent transient speed. The mid-bass, on the other hand, is just adequate. So, the focus is more on the deep, fast sub-bass. For those who enjoy listening to EDM, the mid-bass might feel lacking here, but when listening through the sub-bass, the depth of the sub-bass in the IgniteX Beast can fill the sound and provide a grand impression. For genres like pop, rock, and dangdut, it performs quite well. Even in terms of transient speed, it can keep up with double pedal sections in metal music, although it's not super agile.
The positioning of the bass is also quite unique; it seems to have a separation that makes the bass hits feel somewhat distinct, placed a bit further apart from the other elements. However, it’s not excessively offside. In terms of imaging, the pinpoint accuracy can feel a bit odd and less natural, but it's still enjoyable. It might not be the best choice if your needs involve monitoring, mixing, and mastering. However, for casual listening, this creates a nice sense of extra separation, distinguishing the bass elements from other layers of instruments. This is similar to what I experienced with the CCA CSN IEM.
Mid & Vocals
Moving on to the mid frequencies and vocal presentation, the Celest IgniteX Beast features a unique vocal positioning. Despite the bass being quite prominent, the vocals are still relatively forward or well-placed. This is a great and unique position for an IEM with substantial bass. Indeed, the bass is notably strong in the sub-bass region, while the mid-bass is lesser, and the lower mids dip down before rising again in the mid to upper mid-range, where the vocals come back up.
For male vocals, the thickness is just adequate; in some songs, heavier male vocals may feel slightly thin. However, for female vocals, the presentation is forward and sufficiently thick, with a pleasing sweetness. The timbre from the balanced armature (BA) drivers in the vocals does not come off too BA-ish. One could say that the vocals of the IgniteX Beast are quite natural for a BA character.
Other instruments in the midrange, like piano and guitar, are also presented naturally, with clear, forward, and precise notes. Everything is showcased very cleanly. This IEM is particularly interesting for those who enjoy vocal-centric music but don’t want to lose much bass. It handles shoutiness and sibilance quite safely, making it a solid choice for various listening preferences.
High / Treble
Moving on to the high frequencies or treble, this IEM is not designed for those who are trebleheads. It has a lower treble that can sound somewhat subdued, especially when listening to the initial strikes of cymbals, which may come off as a bit small and pushed back. The mid-treble is also relatively recessed. However, in the upper treble region, it does deliver a pleasing airiness.
Overall, the treble tuning of the IgniteX Beast should be a good solution for those who are sensitive to treble and dislike the forward treble typically found in Harman tuning. While it maintains a nice airy quality, it isn’t sharp or piercing. The tuning ensures that it’s not overly bright or dark, striking a balance that avoids harshness.
This IEM may not be the best fit for those who are passionate about instrumental music, classical genres, or solo performances featuring instruments like guitar and violin, as the treble might lack the necessary bite and presence for those listening experiences.
TechnicalityIn terms of technical performance, one of the most impressive aspects of this IEM is its resolution, clarity, and imaging. The timbre is quite natural for a hybrid configuration of dynamic driver (DD) and balanced armature (BA), featuring solid resolution with clear and precise transitions between notes. The sound is clean and transparent without any muddiness, despite the overall tuning leaning towards a warm character—albeit a clean warmth.
Imaging is also commendable, providing a sense of space that feels holographic and rounded. The depth is well-defined, and both the height and lateral dimensions are apparent, resembling a small sphere. While it may not deliver a grand or expansive soundstage, it feels more like an intimate concert experience in a moderately sized venue with well-placed sound systems. The soundstage is adequate, enveloping the head with evenly distributed sound, and instrument positioning is clear and distinct.
Regarding detail retrieval, this IEM performs well overall; however, the lower treble and mid-treble regions are somewhat recessed. This can result in a lack of perceived detail for those specifically seeking treble detail.
Conclusion & ComparationIn conclusion, the Celest IgniteX Beast may be an excellent choice for those who want a warm tuning while still enjoying forward, sweet, clean vocals free from shouty or sibilant effects, without losing much bass. This IEM is also suitable for those who are not keen on overly forward treble. Especially for lower treble and mid treble, which can often feel piercing, this IEM is very safe while still providing a pleasant airy quality, making it feel clean and clear despite its warm character.
When compared, its closest competitors are the 7Hz Sonus and the Zhulinniao Qingluan Z4.
With the Sonus, the soundstage is wider and the details are better thanks to its treble tuning. Sonus also includes more eartips and a quality pouch. However, in terms of build quality, the IgniteX is superior, while the Sonus cable is better despite its flat appearance resembling kwetiau. Both have good resolution and clarity, but the IgniteX imaging is slightly better in holographic aspects, while the Sonus feels more majestic. For vocals, the IgniteX offers a more natural timbre that is more comfortable for long listening sessions.
Moving on to the Qingluan Z4, its tuning is more neutral with less bass, but it boasts very fast transient speed, similar to planar IEMs like the KZ PR2 or PR3. The vocals on the Qingluan Z4 are more pronounced, although their sweetness is comparable. The IgniteX provides warmer vocals, and at this moment, I prefer listening to the IgniteX over the Qingluan Z4. For those who enjoy treble, the Qingluan Z4 delivers a more special, sparkling treble with greater detail from lower to upper treble. Its soundstage is also wider like the Sonus, but the 3D sensation is better in the IgniteX. Regarding the package contents, the Qingluan Z4 wins with its many eartips and interchangeable nozzles, although I personally dislike the sound from the second nozzle. The Qingluan Z4 also offers a better cable and a hard case, while the Celest IgniteX only includes the IEM, a cable, and six pairs of eartips.
So, is it worth it? For me, yes, it is worth it. It has a unique tuning that is suitable for my collection, and I enjoy its tuning, even though it is not necessarily my favorite or essential. If the IgniteX had slightly elevated mid treble, I would likely enjoy it even more. I tend to focus on vocal-centric music, and the first thing I notice is the vocal tuning and how the timbre sounds. Fortunately, the Celest IgniteX matches my preferences very well, especially considering its solid build quality and beautiful design. Additionally, this is my first IEM with a DSP jack, so it's also a new experience for me to try out a DSP IEM.
As for you all, I suggest asking yourselves if your preferences align with what I described. If they do, this could be worth purchasing. If my description indicates a mismatch with your tastes, it might be best not to buy it, or at least to try it out first if samples are available, or buy it to test and sell it later if it doesn't suit you. For those who prefer not to use the DSP Type-C, a standard 3.5mm SE version is also available.
Okay, that’s it for our review this time. Overall, I really like it, from its unique tonality, technical aspects, to its build quality and beautiful design.
Like if you enjoyed this discussion, comment below if you have any questions, and we’ll meet again in the next review. Alright, thank you very much.

In terms of fitting, this IEM feels really comfortable in my ears, even though its shape mimics a CIEM (Custom In-Ear Monitor) with various curves. It fits me very well, though this might not necessarily be the case for everyone. The sound isolation is excellent for me, without causing any discomfort or fatigue. I’ve had no issues wearing it for hours on end during the day. Even after 3 or 4 hours of continuous use during work—like video editing, voice-over editing, and other tasks that require earphones—I found it quite comfortable.
The cable is also comfortable to wear, with the only minor issue being that the earhooks feel a bit loose around my ears. Other than that, such as the microphonic effect and cable flexibility, there are no significant complaints.
Low / Bass
Let’s start with the low frequencies or bass. This IEM is a bit difficult to label as neutral, especially if all your previous IEMs have been bass-heavy. The IgniteX Beast has substantial sub-bass that hits deep, is impactful, very tidy, and has decent transient speed. The mid-bass, on the other hand, is just adequate. So, the focus is more on the deep, fast sub-bass. For those who enjoy listening to EDM, the mid-bass might feel lacking here, but when listening through the sub-bass, the depth of the sub-bass in the IgniteX Beast can fill the sound and provide a grand impression. For genres like pop, rock, and dangdut, it performs quite well. Even in terms of transient speed, it can keep up with double pedal sections in metal music, although it's not super agile.
The positioning of the bass is also quite unique; it seems to have a separation that makes the bass hits feel somewhat distinct, placed a bit further apart from the other elements. However, it’s not excessively offside. In terms of imaging, the pinpoint accuracy can feel a bit odd and less natural, but it's still enjoyable. It might not be the best choice if your needs involve monitoring, mixing, and mastering. However, for casual listening, this creates a nice sense of extra separation, distinguishing the bass elements from other layers of instruments. This is similar to what I experienced with the CCA CSN IEM.
Mid & Vocals
Moving on to the mid frequencies and vocal presentation, the Celest IgniteX Beast features a unique vocal positioning. Despite the bass being quite prominent, the vocals are still relatively forward or well-placed. This is a great and unique position for an IEM with substantial bass. Indeed, the bass is notably strong in the sub-bass region, while the mid-bass is lesser, and the lower mids dip down before rising again in the mid to upper mid-range, where the vocals come back up.
For male vocals, the thickness is just adequate; in some songs, heavier male vocals may feel slightly thin. However, for female vocals, the presentation is forward and sufficiently thick, with a pleasing sweetness. The timbre from the balanced armature (BA) drivers in the vocals does not come off too BA-ish. One could say that the vocals of the IgniteX Beast are quite natural for a BA character.
Other instruments in the midrange, like piano and guitar, are also presented naturally, with clear, forward, and precise notes. Everything is showcased very cleanly. This IEM is particularly interesting for those who enjoy vocal-centric music but don’t want to lose much bass. It handles shoutiness and sibilance quite safely, making it a solid choice for various listening preferences.

Sound Quality
For sound quality, this IEM has a unique tuning, but for those who don’t have high expectations for sparkling treble, it should still be very acceptable.Low / Bass

Review: Simgot SuperMix4 | Even Better as an All-Rounder Favorite
Hi everyone,
Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Hi everyone,
Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM | I Choose You
Pros: + The availability of 3 nozzle options for tuning
+ Its sound presentation is very clean and clear
+ Good bass texture
+ Clean vocal presentation with clear articulation
+ Decent sound staging and imaging
Cons: - Some may find the vocals thin
- Average instrument separation, but not bad either

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

New Head-Fier
Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Simgot can be considered one of the most consistent brands in releasing new products with top-notch tuning and technical details. From my experience, Simgot is a brand with very few complaints.
Although some of you might be bored with the Harman tuning and might say, “Harman again, Harman again,” for me, who isn’t allergic to Harman tuning, Simgot’s new releases are always something I look forward to.
Some people claim that Harman tuning sounds harsh, but it’s not always the case. Simgot does often use Harman tuning, and one of the most notable models is the EW200, which indeed has a slightly harsh vocal. However, other models like EW100P, EM6L, and EA500LM also use Harman Target tuning but aren’t as harsh as the EW200.
Now, Simgot has released a new IEM that features technology which, while not entirely new, is still rarely seen in budget IEMs.
Previously, I reviewed the Kiwi Ears Quintet, a 3 million rupiah IEM with a Quad-Brid configuration—four different types of drivers that still offer excellent coherence. It uses a Dynamic Driver for low frequencies, Balanced Armature for mids and vocals, Micro Planar for treble, and PZT or Piezo Electric for upper treble and the highest frequencies.
This time, Simgot has released an IEM with similar technology and driver configuration, and comparable technical performance, but at a significantly lower price.
Let’s dive in. Here is my review of the Simgot SuperMix4.
---
THANKS TO
Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:

- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Before we dive into the full review, I want to say a big thank you to Simgot for sending us another sample of their IEMs to test out, evaluate, and review on my youtube channel.
As a disclaimer, Simgot did not provide any brief or specific instructions for this review. They only sent the product itself. So, I have complete freedom to write this review based solely on my personal experience and impressions of the IEMs they sent us.
PRICE
The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The price of this IEM ranges from approximately 2.2 to 2.3 million rupiah.
---
SPECIFICATIONS
Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Let's start with the specifications, everyone. As mentioned earlier, this IEM is powered by four different types of drivers: a Dynamic Driver, Balanced Armature, Micro Planar, and Piezo Electric or PZT.
The impedance is relatively low, surprisingly so, at just 7.2 Ohms, making it quite light. The sensitivity is also fairly high at 120dB, with a frequency response range from 8Hz to 40kHz.
The connection from the driver to the cable uses a standard 0.78mm 2-pin connector, not Type-C.
---
PACKAGING
Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Now, let’s talk about the packaging. Like most of Simgot's other packaging, there’s nothing particularly special about it. The outer box cover is a glossy green, showcasing the driver configuration prominently on the front. This time, the Simgot logo is just a simple circle without the full "Simgot" text. On the back, you’ll find the Harman Target tuning that they always highlight, along with a brief specification written in four languages: Chinese, English, Japanese, and Korean.
When you open the cover, you’ll find a plain black box inside, with a standard mechanism and layout.
Inside, you’ll find the IEM unit, a hard case or carrying case, and within it, the cable and eartips.
---
BUILD QUALITY
Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Regarding the build quality of the components, the eartips and hard case are standard. Simgot hasn’t changed much since the EA500, EM6L, and EA500LM models. This time, they’ve added a touch of luxury by updating the zipper to a gold color, giving it a more premium feel. However, the overall design remains similar.
The eartips are still the same, which I consider to be a good standard. They are among my preferred eartips, and I often mention this in reviews of other IEMs. Ideally, I’d like to see eartips of this quality as a minimum, although I’d be even happier if they included tips with better comfort, like TRN T-Eartips or Moondrop Spring Tips.
For the cable, at this price point of around 2 million rupiah, Simgot has provided an upgraded cable compared to those under 2 million rupiah. It feels more premium, thicker, and more elegant, though it’s slightly stiffer. The cable is OFC Silver Plated, with a gold-plated 3.5mm jack. The jack housing is made of metal, which adds weight and thickness compared to usual. The splitter is also standard, but the chin slider is a bit loose and may slide down when adjusted. A velcro strap is included to help keep the cable tidy when coiled. On the positive side, the cable effectively reduces microphonics.
As for the IEM unit itself, it doesn’t have anything particularly special at first glance. The housing material is resin made with 3D printing, including the nozzle, but the faceplate is designed to be both elegant and simple, with no unusual patterns or cosmetics. It features a central ring or dot and a ventilation hole. The faceplate appears to be metal. The finish and seams are very clean, with no sharp edges. The housing also has ergonomic fins for better grip and good isolation. The overall size of the IEM unit is relatively compact, smaller than the Kiwi Ears Quintet, and not as large as the KZ AS24. It’s slightly thick, so it does protrude a bit when worn.
---
FITTING
With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

With its ergonomic shape and non-metallic material, the SuperMix4 offers a very comfortable fit. The seal is also quite good, and wearing it for extended periods of 3 to 4 hours doesn’t cause discomfort or fatigue. It may protrude slightly when worn, but this doesn’t significantly impact comfort. The ear hooks are also comfortable. Microphonics are relatively well-controlled, though not as clean as the cable on the Dunu Titan S2 we reviewed previously, which does an excellent job at reducing microphonics.
---
SOUND QUALITY
As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM | I Choose You
Pros: + The availability of 3 nozzle options for tuning
+ Its sound presentation is very clean and clear
+ Good bass texture
+ Clean vocal presentation with clear articulation
+ Decent sound staging and imaging
Cons: - Some may find the vocals thin
- Average instrument separation, but not bad either

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

As we know, Simgot has consistently adhered to the Harman Target curve. From the EW100P, EW200, EA500, EA500LM, EM6L, to the SuperMix4, they’ve maintained this tuning approach. However, I haven’t tried the EA1000 Fermat or their flagship EM10 yet.
This time, the SuperMix4 has a more musical tonal character, not as analytical as the EW200 or EM6L, but it still delivers excellent technical performance.
LOW / BASS
Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Starting with the bass, the SuperMix4 delivers substantial mid-bass and sub-bass. The bass is powerful, with a good rumble, solid body, and depth. The mid-bass is energetic and well-textured. However, compared to the EA500LM, the SuperMix4 lacks a bit of transient speed. Overall, the bass is very versatile, handling various genres like rock, dangdut, EDM, jazz, and classical instrumental with ease. It performs reasonably well with metal tracks featuring double pedals, though it’s slightly less agile, with some lingering between beats. It’s not overwhelming like some bass-heavy IEMs, so metal music remains enjoyable, though it may not be the fastest for rapid double pedal sequences. Bass control is good, with clear separation from the mids. Bass enthusiasts might find it satisfying, but those with a preference for extreme bass might find the impact and quantity less intense.
MID & VOCAL
The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
Pros: + Affordable price for its quality
+ Clean and tight bass with good sub-bass extension
+ Neutral and well-balanced mids
+ Crisp and extended treble
+ Spacious soundstage and precise imaging
+ Natural timbre
+ Versatile tuning switches
Cons: - Harman tuning may feel repetitive for some users
- Not suitable for bassheads
- Treble can become aggressive with switches 3 and 4 on
KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The mids and vocals are presented with a slightly forward upper midrange, but not overwhelmingly so. Male vocals in the lower to mid-range are well-bodied and textured, not thin or overly thick, striking a sweet spot for those who favor mid-centric or vocal-centric sound. Female vocals also have good thickness, though some reviewers have noted that upper female vocals can be a bit thin or aggressive. I find it quite acceptable, with good articulation, clarity, and detail. The SuperMix4 handles smooth, rough, thick, and thin vocals well, with safe levels of shoutiness and sibilance, except in some tracks where tuning might be less optimal. Even though the vocals are executed by Balanced Armature drivers, the timbre is quite natural, though not as solid as Dynamic Driver vocals. For Balanced Armature character, the presentation is excellent—clean, without plastic, boxy, or metallic qualities. Instrument presentation in the mid-range, such as guitars or pianos, is also very good.
HIGH / TREBLE
For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.
---
COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.
---
CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.
Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3

SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

For treble, the SuperMix4 uses planar and PZT drivers. The planar driver provides good treble articulation, with well-defined violin overtones, cymbal crashes, hi-hat nuances, and ride cymbal strikes. Everything is well-balanced and precise. Sensitive listeners might detect minor peaks in the cymbals, but it should be acceptable for most. For those who enjoy pop-punk or similar genres with synthesizers, the execution is excellent—detailed and non-fatiguing.
TECHNICAL PERFORMANCE
In terms of drivability, the SuperMix4 is quite easy to drive. Even when directly plugged into a smartphone, it delivers good sound quality. However, for further improvement, I recommend using a DAC dongle. A DAC dongle typically provides a more accurate sound tuning compared to direct output from a phone.
Regarding coherence, despite having four different drivers, the SuperMix4 exhibits excellent coherence. The vocals do not overly emphasize the BA driver characteristics, nor does the treble excessively highlight the planar driver traits. The coherence is impressive, and instrument separation remains superb, with a spacious feel.
The soundstage is very wide, with excellent imaging in both width and depth. The vertical extension is also commendable. The holographic effect is notably present for an IEM in the 2 million IDR price range, especially when paired with a balanced cable upgrade and a well-suited source.
In terms of resolution, clarity, and detail, the SuperMix4 performs very well, especially compared to IEMs under 2 million IDR. The clarity is impressive, with excellent presentation of both detail and micro-detail. The airiness at the high-frequency extremes, combined with precise instrument separation and positioning, creates a luxurious and well-defined soundstage that envelops the listener's head.

COMPARISON
In terms of comparison, I haven't tried many IEMs in this price range. Recently, I had the Hidizs MP145 here. When comparing the SuperMix4 to the MP145, the MP145 is superior in resolution, clarity, detail presentation, and vertical height. However, the SuperMix4 excels in instrument separation, sound staging, and depth. The SuperMix4 provides a more spacious feel with better depth and separation, creating a more immersive stage.
Regarding resolution, clarity, and detail, planar drivers generally have an advantage. The transient speed of the MP145 is better for tracking double pedal in metal music, with a shorter bass decay. Although the SuperMix4 may not be as quick as the MP145, it offers a more versatile tonal quality, suitable for a wide range of music. The dynamic driver in the SuperMix4 provides a more textured, solid, and weighty bass, while the BA driver delivers natural-sounding mids and vocals with excellent sweetness. The micro planar driver contributes detailed, airy high frequencies.
When compared to a more expensive IEM with a similar driver configuration, such as the Kiwi Ears Quintet, I recall the tonal quality being somewhat similar. However, the small peaks around 6 to 8 kHz that were present in the Kiwi Ears Quintet are not noticeable in the SuperMix4. While I don’t remember all the technical details, they are likely similar as well.

CONCLUSION
Alright, everyone, here’s my conclusion on the SuperMix4 in the 2 million IDR price range: worth it. For those of you who may have tried the Hidizs MP145 but found its planar characteristics or housing size less suitable, the SuperMix4 offers great value. I’m still curious to compare it head-to-head with the Kiwi Ears Quintet, which is priced above 3 million IDR.
For those looking to upgrade from the 7Hz Sonus, I compared them briefly and found their tonalities to be quite similar. If you're aiming for a significant upgrade in technical aspects, the SuperMix4 is a solid choice. Especially if you have the 7Hz Sonus with a balanced 4.4mm cable, using that cable with the SuperMix4 can provide a noticeable improvement: more height, better separation, sweeter vocals, and a more solid and powerful bass with slightly quicker speed.
However, I also tried it with a borrowed Oyaide custom cable, which usually enhances performance on other IEMs. For the SuperMix4, though, it made the soundstage feel a bit narrower and instrument separation less distinct compared to the stock 3.5mm single-ended cable. This indicates that SuperMix4 may be particular about cable compatibility. More expensive cables don’t always deliver better performance.
That’s it for this review. If you have any further questions or want to discuss more, feel free to leave a comment, and let’s discuss with others. Don’t forget to like and subscribe if you enjoyed this review of the Simgot SuperMix4, as it motivates me to create even better content.
Okay, that’s all from me. See you next review.

KZ Castor Silver Harman : This IEM is Mispriced!
---
Hello friends,
Today, my desk is piled with review tasks from KZ and CCA. A lot of review work. Besides KZ products, I also have the Hidizs MS3, Tanchjim One, and the Tin Hifi C0. In our previous content, we started discussing CCA again after an 8-month hiatus. Now, let’s talk about the KZ.
On my desk right now, I have the KZ Castor, CCA Polaris, KZ EDX Lite, and KZ ZAT. All these products are from PT Jagat Pramudita Aksata (JPA), which manages several online stores like Toko Kere Hore, Hore.ID, and Knowledge Zenith Store Indonesia, the official distributor of KZ in Indonesia. They offer a complete product range with clear warranties and easy claims. For those interested in buying KZ or CCA products, you can check the links in the description. For other brands like Sgor, JCAlly, F.Audio, iBasso, and 7hz, you can visit Toko Kere Hore or Hore.ID.
Today, I will review the KZ Castor Harman, a dual dynamic driver IEM featuring a switch function, which is a fun feature but can be a bit troublesome for reviewers. Let's get started.
**KZ Castor Harman Review**
I won’t be discussing the KZ Castor Black version today since other reviewers have already covered it. I’ll focus on the Harman-tuned silver version.
In Indonesia, the KZ Castor Harman is priced between IDR 175,000 and 199,000, roughly around IDR 200,000. During the initial launch, the promo price was under IDR 150,000. My first reaction upon trying it was, “This IEM is mispriced, Sir,” implying it was too cheap for its quality. Let’s see why.
Specifications:
- Dual Dynamic Driver configuration: 10mm and 8mm
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
- Frequency range: 20Hz to 40,000Hz
- Impedance: 31-35 Ohms
- Sensitivity: 105dB
- Standard KZ 2-Pin QDC or Type-C connection
- Switch with 4 tunings
Packaging:
The packaging follows KZ’s usual budget style, similar to models like the KZ AS24 or KZ ZAT. It includes:
- 3 KZ Starline silicone eartips
- 1 memory foam tip
- OFC cable in a reddish color
- Tuning switch pin/sim ejector
- User manual and warranty card
Build Quality:
The faceplate design is one of KZ’s coolest, resembling a Yin-Yang symbol. The metal faceplate is silver, with a fully resin housing, including the nozzle. The clear resin allows visibility of the internal components, including the two stacked dynamic drivers, the switch module, and the wiring.
The housing size is moderate, not too small like the Moondrop Chu 2 or too large like the KZ AS24 or ZAT. The nozzle size is standard, not long like the CCA Pianist.
The switch module works oppositely on the right and left sides. The OFC cable is 1.2 meters long with a 2-Pin QDC or Type-C connection, L-shaped 3.5mm gold-plated jack, and a 4-pole design. The right cable includes a microphone.

Sound Quality:
Low / Bass:With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.

The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

With all switches off, the KZ Castor Harman delivers a tight and punchy midbass that is sufficient but not overwhelming. The sub-bass reaches deep, providing a pleasant rumble that adds depth to the overall sound. The bass presentation is clean and fast, capable of handling complex bass lines and fast double kick drums in metal tracks without sounding muddy. For those who prefer a bit more bass, turning on switch 1 or 2 will add more weight to the low end, but even at its maximum bass setting, it doesn’t reach basshead territory.
Vocal and Mids:The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning
Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM.

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The mids on the KZ Castor Harman are neutral and well-balanced, ensuring that vocals and instruments are clear and detailed without being overshadowed by the bass. Both male and female vocals sound natural, with good body and presence. The articulation is precise, avoiding shoutiness and sibilance. When switches 3 or 4 are turned on, the mids become more forward and clearer, but this can introduce a bit of sibilance, especially in tracks that are already prone to it. Despite this, the overall midrange remains pleasant and engaging.
High / Treble:The treble on the KZ Castor Harman is well-extended and crisp, providing plenty of sparkle and air without being harsh. Cymbals and high-frequency details are rendered with good clarity and definition. With switches 3 and 4 off, the treble is smooth and non-fatiguing. Turning these switches on makes the treble more prominent and aggressive, which some might find too intense, but it enhances the overall clarity and detail retrieval for those who prefer a brighter sound signature.
Technicalities:- Timbre: The timbre is natural and lifelike, thanks to the absence of BA drivers, which can sometimes sound artificial.
- Soundstage: The soundstage is spacious, with a good sense of width and depth, creating an immersive listening experience.
- Imaging: Imaging is precise, with clear placement of instruments and vocals, providing a decent sense of 3D space.
- Resolution, Clarity, and Detail: The resolution is impressive for its price, with clear and well-defined notes. The clarity and detail retrieval are enhanced when switches 3 or 4 are on, although the tonal balance might not be to everyone’s taste in this configuration.
- Separation and Positioning: Instrument separation and positioning are solid, benefiting from the dual dynamic driver setup, which helps to maintain a clear and organized soundstage.
Conclusion:
The KZ Castor Harman offers a popular tuning with many competitors. It might feel familiar to those who frequently change IEMs. However, for fans of the Harman tuning seeking a more energetic experience than the KZ D-Fi or better technicalities than the Simgot EW100, the KZ Castor Harman is a worthy choice.
Considering the price, finding faults with the Castor Harman is challenging. Its Harman tuning might be repetitive for some, and bassheads might find the bass lacking. Those sensitive to peaks may have limited tuning options due to the switch effects.
Comparisons:
- KZ D-Fi: Better build quality with a full metal design and a more neutral tuning.
- KZ Krila: For those who dislike BA timbre, the Castor offers a more natural sound with similar technicalities.
- TRN MT1 Max: The Castor wins in technicalities, soundstage, separation, and clarity.
- CCA Polaris: This will be covered in a future review.

Yeah. Budget IEM but offers more and more value than its price.
Senketsu
The bass is boosted, if that's still not enough, you can use the equalizer. As someone who loves low tones, I confirm that I am happy with the power of the bass. I also have the KZ Castor bass version, but I haven't tested it yet.

Hidizs MP145 Review :
"I Love This Blue Whale"
Introduction
Hello everyone! Here, we're diving into another IEM from Hidizs. This is the third product from Hidizs that we're reviewing here.
Previously on my YouTube channel, Alba Project Review, we reviewed the Hidizs MS1 Galaxy, a budget-friendly IEM with a bass-heavy profile, albeit slightly overpriced in my opinion. Then we explored the Hidizs MS3, which impressed us with its tuning, technical capabilities, build quality, and packaging at a price range of around 1.6 to 1.8 million IDR.
Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.

Now, we're looking at something equally impressive. From packaging to build quality and technical performance, let's dive into my review of the Hidizs MP145, affectionately nicknamed the Blue Whale.
Acknowledgements
Firstly, I'd like to thank Hidizs for sending us this review sample. Hidizs has been a notable player in the portable audio scene, offering a range of products from DACs to DAPs and upgrade cables. I'm particularly intrigued by their Hidizs AP80 Pro X DAP. Hopefully, we can review that soon as well.
Pricing
The Hidizs MP145 is priced at $159 USD, which translates to about 2.4 million IDR. This places it in a competitive range alongside models like the 7Hz Timeless and the Dunu Talos.
Packaging
At first glance, the packaging seems standard, with a black cardboard box featuring the IEM's image and specifications. However, once you open the outer cover, you'll find a plastic or mica box inside, providing a unique touch compared to the typical paper or cardboard packaging of most IEMs.
Package Contents
The package includes:
1. The IEM unit (Blue Whale)
2. 2-Pin cable (I opted for the 4.4mm jack instead of the 3.5mm)
3. A pouch, similar to the one that comes with the Hidizs MS3
4. Nine pairs of eartips, divided into balanced, vocal, and bass tuning sets
5. Two additional nozzles: silver for vocal tuning and red for bass tuning, with the rose gold pre-installed for balanced tuning

Specifications- 14.5mm Ultra-large Planar Magnetic Driver
- Whale Tail & Rorqual Pleats Design Inspiration
- Hidizs Pneumatic Sound Tuning Filter
- Target H-2019 Curve & Hidizs Style Professional Tuning
- Fully Symmetrical Magnetic Circuit
- Hidden Bionic Breathing Holes
- 6N Silver-Plated Single-Crystal Copper Wire
- Ergonomics Design with Comfortable Extended Wear
- Ergonomics Liquid Silicone Ear Tips
- Customized Pouch for MP145
- 3.5mm or 4.4mm cable optional
- 0.78mm 2-Pin Cable
- Hi-Res Certification
Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

Build Quality
** Eartips **The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The eartips are reminiscent of Acoustune AET07 in terms of material. They are well-made, and the inclusion of a holder ensures they don’t get misplaced. The set includes nine pairs, with three pairs each for balanced, vocal, and bass tuning.
** Cable **The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The cable feels better than the one included with the MS3. It’s more flexible, less prone to microphonics, and lighter. Made from 6N Silver Plated Crystal Copper, it has a straight, balanced, gold-plated 4.4mm jack, and the housing is made of solid metal.
** Pouch **The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The pouch is similar to the one provided with the MS3, though I’d prefer something a bit more premium at this price point, like a hard case.
** IEM Unit **The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The housing is made from Aviation Grade Aluminum Alloy, giving it a solid feel. The design inspiration comes from a whale’s tail, and while the size might be intimidating, the build quality is exceptional.
Fitting
Fitting can be a challenge due to the size of the housing, but once properly adjusted, it’s quite comfortable. The large size does protrude slightly from the ears, but it doesn’t affect the comfort. The short, wide nozzle ensures a good seal without causing discomfort.
Sound Quality
** Drivability **The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.
** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM | I Choose You
Pros: + The availability of 3 nozzle options for tuning
+ Its sound presentation is very clean and clear
+ Good bass texture
+ Clean vocal presentation with clear articulation
+ Decent sound staging and imaging
Cons: - Some may find the vocals thin
- Average instrument separation, but not bad either
- Lack of airiness
Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The MP145 is relatively easy to drive. A volume setting of 75 was sufficient for me, compared to higher settings required by other planars like the KZ PR3.
In this review, I used the original cables and eartips that came with the Hidizs MP145. For the source, I used the F.Audio T3 DAP, the Fiio KA13 DAC, and the JCAlly JM6 Pro. Here, I did not turn on the high gain mode at all.

** Low / Bass **The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsU
Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Simgot Never Disappoints Me
Pros: - Clean and textured sub-bass
- Elegant and luxurious design
- Clear and smooth mid-range presentation
- Good detail and clarity in the treble
- Comfortable fitting without any issues
Cons: - Lack of a lip on the nozzle makes changing eartips a bit difficult
- Fingerprint magnet on the glossy black resin shell
- Cable quality is not outstanding
- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The bass presentation is clean and fun. Even with the balanced nozzle, the bass is impactful and well-controlled, delivering a dynamic and weighty performance typical of planar drivers. The sub-bass is deep and impactful, almost reminiscent of dynamic drivers, which is rare for planar IEMs. Switching to the bass nozzle further enhances the bass response, making it richer and more prominent, ideal for bass-heavy genres like EDM and orchestral music.
** Mid and Vocals **The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

7Hz Sonus:
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.
Contents
The package includes:
- Bilingual User Manual (English and Chinese)
- IEM units with foam stands
- A pouch or small bag
- A set of cables
- Six pairs of silicone eartips (3 wide bore, 3 standard)
- Two pairs of spare filters
Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.
Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.
See you next time!

Zhulinniao Qingluan Z4:
A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Introduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

- Guitar Distortion can be soft and lack bite at times
Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.
Specifications
- 1DD + 4BA Hybrid Drivers
- Tuned Towards the H-2019 Target Curve
- Impedance 26Ω±15% (@1kHz)
- Sensitivity 119dB/Vrms (@1kHz)
- Frequency Response Range 8Hz-40kHz
- Earphone connector 0.78mm QDC
Packaging
For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMs
- A cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover
- 3 pairs of silicone eartips
- 1 hard case
- User Manual
IEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.
My Setup
- Stock Cable
- Stock Eartips size S
- DAP: F.Audio T3
- DAC: Acmee Phantom Sound 4S
- Laptop: Asus ROG Strix G531G
- Music Player: Hiby Music, Spotify, Fiio Music, Apple Music
SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.

The mids are clean, detailed, and carry a good weight. Male vocals could use a bit more thickness but remain acceptable. The vocal positioning is neither too forward nor recessed, offering a pleasant listening experience without any harshness or sibilance. The balanced nozzle provides a good balance, while the vocal nozzle pushes the mids slightly forward, adding more warmth and body to the vocals.
** High / Treble **The treble is bright and detailed without being piercing. The presentation is smooth with good extension, providing a sense of airiness and sparkle. The balanced nozzle gives a nice, balanced treble, while the treble nozzle accentuates the high frequencies, making it more suitable for treble enthusiasts who appreciate a brighter sound signature.
**Technical Performance**The MP145 excels in technical performance, with a natural timbre that sets it apart from other planar IEMs. The resolution and detail retrieval are top-notch, allowing every nuance in the music to be heard clearly. The soundstage is wide and spacious, providing a three-dimensional listening experience with excellent imaging and instrument separation.
Conclusion
At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.
If you're interested in hearing more, I've also released a detailed video review on my YouTube channel, Alba Project Review. Check it out for a more in-depth analysis and sound demonstrations.

At approximately 2.4 million IDR, the Hidizs MP145 is a strong contender in its price range. It offers impressive packaging, solid build quality, and exceptional sound performance. The ability to fine-tune the sound using different nozzles and eartips adds to its versatility, making it suitable for various music genres and personal preferences.

Every Song Sounds Good with These IEMs
Every Song Sounds Good with These IEMs
Hey friends!
A few weeks ago, I got to borrow a set of IEMs from a friend—one that has been quite hyped and frequently recommended for under $60. After using it for a few days and comparing it with some of my other IEMs, I now understand why people love it so much.
Here i’'m sharing my review of the 7Hz Sonus.

Here i’'m sharing my review of the 7Hz Sonus.
Disclaimer
Please note that this review is entirely based on my personal opinions. I borrowed the IEMs from a friend who purchased them, and there is no sponsorship involved.
Price
Currently, the 7Hz Sonus is priced around $60 USD. In Indonesia, as of June 6, 2024, it costs between IDR 977.100.
Specifications
The 7Hz Sonus features a hybrid configuration with 2 drivers: 1 Dynamic Driver (DD) and 1 Balanced Armature (BA). It has an impedance of 30 Ohms, a sensitivity of 109dB, and a frequency response of 10Hz to 20KHz. The cable connection is a universal 2-Pin 0.78 mm.
Zhulinniao Qingluan Z4: A Budget Audiophile Gem, Segmented but I Love It
Hello, friends!
What I have here might be somewhat niche in its tonality, and it might not be everyone's cup of tea. However, I absolutely love this IEM, from its tonal balance, technical performance, build quality, to its housing and faceplate design.
Alright, friends, here is my review of the Zhulinniao Qingluan Z4, a Single Dynamic Driver IEM.
THANKS TO
First, I want to extend a huge thanks to Zhulinniao from China for sending us this sample to review. This is the second IEM they've sent us, the first being the Zhulinniao Jinghong, which we've also reviewed on my youtube channel.
DISCLAIMER
As a disclaimer, all the content and opinions in this video are 100% my own. What I find good, I'll say is good. What I don't like, I'll be honest about. These are my personal opinions and may differ from others.
PRICE
Let's start with the price. Before the item arrived, I already knew it costs $45 USD. Converting to the current exchange rate, that's around 730,000 IDR.
SPECIFICATIONS
Let's go over the specifications. This IEM is powered by a single 10mm Diamond-Like Carbon (DLC) dynamic driver.
Frequency range: 20 Hz to 20 kHz
Impedance: 32 Ohms
Sensitivity: 106dB
The nozzle uses a detachable filter system.
PACKAGING / BOX
When the package arrived, I was surprised by how big the package was. It wasn't the usual size for an IEM package. At first, I thought there might be two units inside.
But upon opening it, there was just one unit, in a box bigger than most smartphone boxes. This might be the largest IEM box I've reviewed on my youtube channel, even larger than the previous Zhulinniao Jinghong.
Regarding the box, you can see it compared with the packaging of the Simgot EA500LM, KZ PR3 and Tanchjim Zero.
From the packaging, Zhulinniao Qingluan Z4 shows a lot of intention.
There are Chinese characters on the outer part, which I can't read, but we can use a translator camera apps. The text is in gold, giving a traditional yet luxurious feel. Even the back has the same gold text. The material and ink used for this cover’s text seem to be more expensive than most IEMs in this price range.
The main box is very thick, providing good protection for the contents.
There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
Packaging
The outer packaging is monochromatic black and white with "SONUS" prominently displayed, along with a mockup of the IEM, the 7Hz logo, and some Chinese text. The back has brief specifications and details about the components and materials used.
Inside, the box is orange, made of thick cardboard with a textured finish, which feels sturdy enough to protect the contents from light impacts. Upon opening, there's a clear plastic cover, and underneath, we find the package contents.

Contents
The package includes:

Build Quality
Pouch: The pouch is well-designed, made from thick synthetic leather with a snap-button closure. While it offers protection from scratches and minor falls, it's not the best against strong pressure. I prefer the sturdier pouches like those from Simgot, but this one is decent.
Eartips: The eartips are a significant improvement over those that come with the 7Hz Salnotes Zero. They're of good quality, comparable to Simgot’s eartips, with a slightly thicker flange. The package includes six pairs, which is generous. They fit comfortably and don’t affect the sound negatively.
Cable: The cable is high quality, made from OFC silver-plated material, with a unique 3.5mm jack housing. However, its flat, ribbon-like design is unconventional. Despite this, it performs well, with no major issues aside from some microphonics when in motion. The ear hooks are comfortable and the connectors are standard 2-Pin 0.78mm.
IEM Unit: The IEMs are lightweight with a resin shell and possibly an aluminum alloy faceplate. The finish seems prone to scratches, especially at the edges. The ergonomic design with fins provides a good fit, although it might not suit everyone’s ears. The nozzles, made of resin, feature a star-shaped filter.

Fitting
Fitting
The ergonomic design and eartips offer a comfortable fit with good sealing and minimal discomfort. There is some microphonics when the cable rubs against surfaces, but overall, the fit is secure and comfortable.
Setup
For this review, I used the stock white-pink eartips and cable, with sources including the Fiio KA13 DAC dongle, JCAlly JM6 Pro, and KZ AM01.
Sound Quality
General Tonality: The 7Hz Sonus leans towards a slightly neutral sound signature with a mild mid-bass elevation and extended sub-bass.
Comparison: I compared it with the Zhulinniao Qingluan, which is slightly cheaper, and the Simgot EA500LM, which is a bit more expensive. The Sonus sits in the middle price range.
Drivability: The Sonus is slightly harder to drive than the Simgot EA500LM but not excessively so. A budget DAC dongle can help maximize its potential.
Low / Bass: The bass is well-balanced, with sufficient mid-bass punch and deep sub-bass. It performs well across various genres, though it’s not overly punchy or engaging for bass-heavy tracks. Compared to the Qingluan Z4 and EA500LM, the Sonus offers the most bass quantity, but the EA500LM has better bass texture and dynamics.
Midrange & Vocals: The midrange, especially vocals, is the highlight. The Sonus delivers sweet, warm vocals that are soothing and well-positioned, making it ideal for genres like Pop, J-Pop, and K-Pop. It might not excel with aggressive vocals in rock or metal, but overall, it’s pleasing and articulate.
High / Treble: The treble is neutral and not overly emphasized, making it safe for those sensitive to high frequencies. While not as extended or detailed as the EA500LM or Qingluan Z4, it provides a balanced and airy sound.
Technicalities: The Sonus offers good resolution and detail, though not exceptional. The soundstage is wide, but imaging is average, providing a decent sense of space. Instrument separation is adequate but not outstanding compared to pricier IEMs.

Conclusion
Is the 7Hz Sonus recommended? Yes, if your budget doesn’t stretch to the Simgot EA500LM. The Sonus is a versatile option suitable for various music genres, offering pleasant vocals, good bass, and balanced treble. However, it may not satisfy those seeking perfection in specific genres or those who need exceptionally fast bass response.
That’s my review of the 7Hz Sonus. If you enjoyed this review, give it a like, leave any questions in the comments below. Don’t forget to subscribe to my YouTube channel for more IEM reviews.

There's a Bamboo Forest Bird logo, likely the company name.
Now, let's look inside.
For $45 USD, or around 730,000 IDR, this is what you get.
You get the IEM units, 9 pairs of eartips, 2 pairs of detachable nozzles (one already on the IEM), a hard case, a high-purity OFC silver-plated cable with a gold-plated 3.5mm jack, rubber rings for the nozzles, a user manual, and a warranty card.
BUILD QUALITY
Carrying Case
The carrying case is well-made with good stitching, though I'm not a fan of the color. It looks dull, but it's sturdy and has a smooth zipper. The inside is lined with soft wool-like fabric to prevent scratches.
Eartips
Out of the 9 pairs, there are 3 different types in terms of shape and material. The green ones are the most unique and softest. However, none of them fit well with the Zhulinniao Qingluan Z4 for me. Interestingly, the green ones fit perfectly on my KZ Castor Harman, Tanchjim Zero & Soundcore R50i.
Cable
The cable is impressive, resembling the SGOR Adonis but slightly thicker. It uses 102 core, dual strand, OFC - silver-plated material. Despite its thickness, it’s flexible and feels like rubber. It's also non-microphonic. The 3.5mm gold-plated jack is sturdy with a metal housing. The splitter and chin slider are made of metal and rubber. The ear hooks fit comfortably, and the pins are universal 0.78mm 2-pin.
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.
Fosi Audio PH05 : Simplifies My Work
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM | I Choose You
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.
Simgot Never Disappoints Me
The IEM
The IEM units are aesthetically pleasing with a unique leaf-like design on the faceplate, featuring different textures. One side is smooth chrome with a bamboo forest bird logo and cloud patterns, while the other is textured like fine sandpaper. This finish makes the IEM resistant to fingerprints.
There are two vents: a long one on the faceplate with a filter, and a small one on the back. The metal nozzles are detachable, with an extra pair for a brighter tuning.
FITTING
Despite the beautiful design, the fit is a bit disappointing. It’s comfortable due to its smooth surface and small housing, but the seal is not tight enough, affecting the sound quality.
For the sound quality discussion later, I'll be using Acoustune AET08 eartips, which provide a better fit and seal for me.
DRIVABILITY
The IEM with 32 Ohm impedance and 106 dB sensitivity requires a bit more power to drive compared to others like the Simgot EA500LM. It needs a higher volume to achieve the same loudness.
REVIEW SETUP
For this review, I used the Fiio KA13 dongle DAC for a neutral-bright sound and the F.Audio T3 DAP for a warmer sound with boosted sub-bass and midbass, warm and thick vocals, and smooth treble.
Eartips: Acoustune AET08
Cable: stock
Nozzles: stock
SOUND QUALITY
The sound quality of the Zhulinniao Qingluan Z4 is quite intriguing. It has a very neutral tonality with slight boosts in the treble and sub-bass.
Its overall tonality is similar to the Tanchjim Zero, an IEM whose tonality I have always liked but never found a true upgrade for until now. This tonality is quite niche and not widely popular, but for those who focus on mid-centric or vocal-centric IEMs with good technicalities, I highly recommend this IEM for under $50 USD.
LOW / BASS
The bass might seem boring to some, especially those who like V-shaped and fun bass.
With the Fiio KA13, the bass is very neutral in the mid-bass, present but not overpowering, with good sub-bass punch and dynamics. The transient-speed is quick, with minimal rumble.
With the F.Audio T3, the mid-bass is thicker and slower, making it more musical and fun.
For genres like metal, rock, jazz, pop, and instrumental, the Z4 is great on both F.Audio T3 and Fiio KA13.
However, for bass-heavy genres like EDM, hip-hop, or dangdut, the Z4 might feel underwhelming due to its thinner and less engaging mid-bass and lower midrange.
MID & VOCAL
The mids and vocals are the highlight for me. The vocals are warm, not flat or dry, soft yet detailed without being harsh. This IEM presents details naturally without causing fatigue.
The vocals' thickness is just right, and the mids are very clean.
Using Acoustune AET08, the vocals are clear and emotional, with a natural timbre. Acoustic guitars, electric guitars, pianos, and midrange instruments sound lively and detailed.
HIGH / TREBLE
The treble is detailed but not sharp. It's not overly extended, with moderate airiness and breath. The treble presentation is clear and bright enough without being harsh.
The Z4 handles high frequencies like cymbals, violins, and snare drums well, providing clarity without sibilance or shoutiness when paired with Acoustune AET08.
WHY AET08? WHY NOT STOCK EARTIPS?
I use Acoustune AET08 for three reasons:
1. They provide a better fit.
2. They offer a tighter seal.
3. They enhance the sound, making the bass and vocals thicker and reducing some brightness and sibilance.
TECHNICALITIES
The timbre of the Z4 is natural and clear, with minimal coloration. It's free from metallic or plasticky sounds.
Resolution, clarity, and detail are impressive for a non-planar IEM at this price. The soundstage feels wide and spacious, with decent height and depth, creating a good 3D imaging effect. Instrument separation is clear, though not overly spacious.
COMPARISONS
7Hz Sonus
I've only briefly tried the 7Hz Sonus. It has more sub-bass quantity and depth compared to the Z4. The mids are similar, but the Z4 is clearer and more energetic. Both have sweet vocals, but the Z4 is more detailed.
Simgot EA500LM
The EA500LM is easier to drive. The tonality and technicality, both are similar. The Z4 has a cleaner and clearer midrange with faster transient-speed of bass. The EA500LM has deeper bass, better rumble, and slightly more refined micro-details. The soundstage and imaging of both are comparable, with the EA500LM having a slight edge in 3D sensation and overall resolution.
KZ PR3
Compared to the KZ PR3, the Z4 has better dynamic punch and natural mids. The PR3 is faster in transient response but can be more fatiguing due to its treble extension. The Z4 has a more natural timbre and a wider soundstage.
CONCLUSION
That's my review of the Zhulinniao Qingluan Z4. In summary, this IEM has a niche tonality that might not appeal to everyone, especially in the current market filled with Harman-ish or V-shaped tunings. But for those looking for a mid-centric IEM with natural timbre, clean midrange, and non-fatiguing detail retrieval, this IEM is highly recommended.

Fosi Audio PH05 : Simplifies My Work
https://www.youtube.com/watch?v=cHr0rRhuKsUIntroduction
In this issue, we delve into the Fosi Audio PH05 amplifier. Recently, I shared an unboxing video for this device. If you missed it, check the link below.
First, a huge thank you to Fosi Audio for sending this amplifier sample for review. This unit will be incredibly useful for comparing different in-ear monitors (IEMs), earphones, and even headphones.
Now, let’s get into the detailed review of the Fosi Audio PH05 amplifier, priced at approximately $39.99 or around IDR 640,000. This amplifier offers 5 output channels, each with a substantial power output of 310mW, making it suitable for both light and somewhat heavy drive IEMs, such as the KZ PR3.
Pricing
As mentioned, the Fosi Audio PH05 is priced at $39.99, which converts to around IDR 640,000 at the current exchange rate. Despite the high exchange rate of IDR 16,000 per USD, this price remains competitive. Let's hope for economic improvement in Indonesia soon.
Specifications
The Fosi Audio PH05 offers the following specifications:
- Rated Power Output: 310 mW
- Impedance: 16 Ohm to 300 Ohm
- 1 input and 5 outputs, all with 3.5mm interfaces
- Signal to Noise Ratio (SNR): 105dB
- Frequency Response: 20Hz to 20KHz
Packaging
The packaging is simple, featuring a black cardboard box with an illustration of the amplifier and some basic text. It remains to be seen if this is the final packaging design for retail units.
Unfortunately, not only is it minimalist, but it also doesn't attract attention at all.
Accessories
Inside the box, you’ll find:
- 1 unit amplifier
- 1 UK-standard plug adapter (a converter may be needed)
- 1 auxiliary cable (3.5mm to 3.5mm headphone jack)
- 1 user manual
Build Quality
The amplifier’s build quality is reminiscent of the F.Audio T3, with a solid metal or aluminum alloy construction that feels both heavy and durable. Although portable, this amplifier is better suited for desktop use as it requires an external power source.
Key features include:
- Orange on/off button, which is clicky and stable
- Solid volume control knob with smooth operation
- Inputs and outputs that fit snugly, without being too tight or loose
- LED indicators for power and mute status
Usage
To use the amplifier:
1. Prepare the unit.
2. Plug the adapter into a power source, using a converter if necessary.
3. Connect the adapter to the amplifier’s 12V DC input.
4. Plug one end of the auxiliary cable into your audio source and the other end into the amplifier.
5. Connect your headphones, earphones, or IEMs to the amplifier.
Sound Quality
The sound quality of the Fosi Audio PH05 is a key aspect to consider, especially given that it functions purely as an amplifier without an integrated Digital-to-Analog Converter (DAC). This means that the PH05 does not impart its own tonal characteristics but instead faithfully amplifies the signal from the audio source. Here’s a detailed breakdown of the sound quality aspects of the PH05:
Tonality and Frequency Response
Since the PH05 lacks a built-in DAC, its tonality remains true to the original audio source. However, during extensive testing, a slight increase in frequencies between 6 KHz and 10 KHz was observed. This can cause certain IEMs, especially those already on the brighter side, to sound even more pronounced in those frequency ranges. Users sensitive to high frequencies may need to adjust their equalizer settings to reduce potential sibilance and ensure a balanced listening experience.Despite this minor adjustment, the PH05 does an excellent job of maintaining the integrity of the source material, ensuring that the amplified sound is clear and precise. The wide frequency response range of 20Hz to 20KHz ensures that the PH05 can handle the full spectrum of audio, from deep bass to sparkling highs.
Dynamics and Power Handling
One of the standout features of the PH05 is its ability to enhance dynamics and provide substantial power output. Each of the five channels delivers 310mW, which is significant for an amplifier in this price range. This power boost is especially beneficial for IEMs and headphones with low sensitivity or higher impedance. The enhanced power not only increases volume but also improves the dynamic range, making bass hits more impactful and sub-bass frequencies more pronounced.In practical terms, when pairing the PH05 with dongles like the Fiio KA13, JCAlly JM6 Pro, KZ AM01, and J3 Eline, the amplifier noticeably enhances the overall listening experience. The bass becomes deeper and more defined, the mid-bass punchier, and the overall sound more vibrant and lively. This dynamic enhancement is particularly useful when comparing multiple IEMs, as it ensures that each unit receives adequate power for optimal performance.
Noise
While the PH05 excels in many areas, it does introduce some noise, particularly noticeable with high-sensitivity IEMs. This hissing or noise floor is a common issue with amplifiers that lack a DAC, as they simply amplify the incoming signal, including any background noise. The level of noise varies with the sensitivity of the connected device; for instance, Simgot EA500LM exhibited more noticeable noise compared to less sensitive IEMs like the KZ PR2 and KZ PR3.
However, this noise is generally not intrusive and does not detract significantly from the overall listening experience. For many users, especially those using the amplifier in a desktop setting or for specific purposes like audio reviews and comparisons, the benefits of the PH05 far outweigh this minor drawback.
Use Cases
The Fosi Audio PH05 is ideal for users who:
- Watch content in groups (up to 5 people) using IEMs or headphones
- Need to monitor multiple headphones or IEMs simultaneously for mixing and mastering music
- Require a device for podcast monitoring
While it might not be essential for everyday use, its benefits for specific scenarios like reviews and comparisons make it a worthwhile investment.
Conclusion
In summary, the Fosi Audio PH05 amplifier is a versatile and valuable tool for those needing to drive multiple audio devices or perform detailed audio comparisons. Its affordability and functionality make it a practical choice for various specialized applications.

Simgot EA500LM
"I Choose You"
Alright, folks. This time, we're going to discuss another IEM from Simgot. Actually, this product has been launched for quite some time, a few months ago, but the samples for review were only sent by Simgot from China last mid-Ramadan, and it was just towards the end of Ramadan that the product arrived in my hands, here in Jogja, Indonesia.
Now, the one we're going to talk about this time is the SIMGOT EA500LM.
*THANKS TO SIMGOT*
First of all, I would like to express my gratitude again to Simgot for sending this IEM sample for us to review on this forum and also on my YouTube channel, Alba Project Youtube Channel. For those who are interested or curious, you can check the link I provided in the description of my YouTube video.
*PRICE*
As for the price, the EA500LM is currently priced at $80.99 USD on Linsoul as of the date of this writing (April 15, 2024), while it's not yet available on simgot.com, I'm not sure why. Meanwhile, in my country, Indonesia, there are already several stores selling this IEM for around Rp 1,300,000 to Rp 1,400,000.
The price is not much different from the Simgot EM6L that we reviewed earlier.
*SPECIFICATIONS*
In terms of specifications, the Simgot EA500LM differs from the Simgot EM6L. While the Simgot EM6L has a configuration of 1DD plus 4BA, the EA500LM uses only a single dynamic driver. For those of you who are fans of Single Dynamic Driver, pay close attention to this review.
It has an impedance of 21 Ohms, sensitivity of 123 dB, frequency range of 10Hz to 50,000 Hz. The connection from the driver to the cable uses a 2-pin 0.78mm connector. Also, the driver uses a Lithium Magnesium Alloy diaphragm. Hence the name LM. The size of the dynamic driver is standard, 10mm, with dual cavities and dual magnets.
In the EA500LM, we can also change the sound tuning using its detachable nozzles, similar to the older EA500, unlike the EM6L which doesn't have this feature. The tuning using these nozzles results in a significant difference.
Now, considering the comparison between the EA500LM with its single DD and the EM6L with its 5 hybrid drivers, what makes the EA500LM's 1DD special, and why is its price equivalent to the EM6L's with 5 drivers? We'll discuss that later. For now, let's talk about the packaging.
*PACKAGING*
As for the packaging, the box model is similar to the EM6L, with the only difference being the artwork.
While the EM6L had a phoenix bird-like image, this time the EA500LM's image is more like classical astronomical paintings, with images of the sun, stars, or planets, reminiscent of Abdurrahman Al Sufi's style.
As usual, there's the Simgot logo on the top left, the Hi-Res logo on the right, below there's a hand either praying or offering something to the universe, and below that is the EA500LM label.
On the back, there are specifications, etc., along with the frequency response graph.
*ACCESSORIES*
As for the accessories, the EA500LM is similar to the EA500 and EM6L. The only difference is that the EM6L doesn't come with additional nozzles for tuning like this. Also, there's a black and red rubber ring.
Other than that, it's the same: clear unit, ear tips, just three pairs, then there's the high-quality hard case that Simgot always provides, inside there's a High Purity OFC Silver Plated cable. Plus, there's a manual booklet in Chinese and English, and a warranty card.
*BUILD QUALITY*
For the build quality, the pouch is the same as the EM6L's, and I like this pouch, it's sturdy, strong, and can accommodate both a small DAP and the EA500LM IEM. So, if you want to be compact, you can just carry this one pouch everywhere.
I also like the IEM unit itself, it's made of full metal and really sturdy, hard, with a very smooth finish, with just the Simgot logo on the left driver and the LM logo on the right side. This LM logo reminds me of the Mobile Legends logo, but reversed, in Mobile Legends it's ML, and this one is LM.
On the inside, there are two vents, there's something like a bolt, but I don't know what it's for, and there are L and R markings.
The nozzles are also metal, and the filters inside are aluminum.
So overall, it looks very solidly built.
As for the internals, there's one Dual Magnet dynamic driver, size 10mm, with a diaphragm or membrane made of Lithium Magnesium.
The cable is exactly the same as the one from the Simgot EM6L, except this time it doesn't use QDC connectors. This time it's more universal with 2 Pin 0.78mm connectors. The looks are typical Simgot cable, the cable diameter is also not large, it's small, and the cable is soft, not stiff. In daily use, this cable also feels comfortable, there's no noticeable microphonic effect here.
The ear tips are also standard Simgot. I've known for a long time that Simgot provides ear tips like this, they're quite good, the flanges are soft, a bit stiff but still comfortable.
*FITTING*
As for the fitting, Simgot always fits me well, starting from EW100P, EW200, EM6L, up to this EA500LM, they're all comfortable. The housing size is also never too big, even though the EM6L has many drivers, it can still be made compact. Small, smooth, in the ear, it feels immediately comfortable.
For use on a laptop or PC, the metal material is safe, there's no hint of buzzing even when the laptop is charging. Not like the KZ D-Fi which can cause slight buzzing and itching in the ears when plugged into a laptop.
*SOUND QUALITY*
Moving on to the sound quality discussion.
Let me first tell you about its drivability, the EA500LM is quite easy to drive. In terms of volume, even the EA500LM requires less power than the KZ Castor Harman. So, you don't really need a powerful amplifier to drive this EA500LM. The consideration is more towards a source with good sound quality. As for power, it's hardly something to worry about. It's easy.
Also, I need to mention this so that you guys have a better idea of the tonality and technicality of the EA500LM when paired with your devices or sources.
For my own testing of the EA500LM, I used a Fiio KA13 DAC source priced around Rp 1.300.000 IDR, its tonality is slightly neutral with a hint of brightness but has an extra bass kick that makes the sub-bass a bit deeper but still tight and tidy. From the midrange to the highs, it also tends to be slightly crisper. The power output here is also quite significant; well, if it's good enough for KZ PR2 or PR3, then it's sufficient for driving the EA500LM.
Secondly, I used an F.Audio T3 DAP source priced around Rp 900.000 IDR, this one also has a large power character, but not as big as the Fiio KA13. Its tonality is still relatively neutral, but the warmth here is warmer than the Fiio KA13, and it also has quite a bit of smoothing in the range of 7 to 9 kHz, making its character more musical. Additionally, it can better control peaks in the upper midrange, and it can tame sibilance and shoutiness better. The Fiio, on the other hand, is more suited for analytical listening.
Third and fourth, I also connected the EA500LM to cheap dongle DACs costing less than Rp 200.000 IDR, even less than Rp 100.000 IDR. Here, I used the KZ AM01 and the KZ X J3 Labs Audio, known as J3 Eline. They both have the Conexant CX31993 chip, which generally has a tuning from neutral to bright with minimal noise, providing clean sound and decent detail. The AM01 has a secondary independent amplifier, the MAX97220, with a power output of around 60 mW, similar to the JCALLY JM6 Pro, but with a cheaper build quality, especially in the slightly stiff cable.
The remaining connections were made to the Infinix Note 30 smartphone with a DTS sound profile set to Traditional, with bass boost and vocal and treble enhancements turned off, and another connection was made to the Asus ROG Strix G531G laptop.
*TUNING*
For the tuning, I'll be using the Silver Nozzle - Red Ring primarily. After that, we'll discuss how it changes when swapped with the Gold or Silver Nozzle - Black Ring.
*TONAL*
Generally, the Simgot EA500LM with the Silver Nozzle - Red Ring tends to have a Mild V-Shaped or U-Shaped sound signature, with a focus on boosting the Sub-Bass and the Upper-Mid to Mid-Treble range. However, it's not extremely V-Shaped. It's more of a mild V or U shape.
*LOW / BASS*
In terms of low or bass frequencies, it's not entirely neutral; we get a really good depth in the sub-bass, nice texture, tidy mid-bass, and the overall bass’s presentation is very clean. Extremely clear.
However, in terms of its impact on the lower mid-range or vocals, the lower-vocal doesn't thin out too much.
This low’s transient isn't lightning-fast, but it's still considered very versatile. What I mean is, when we need quick bass for chasing double pedal beats in metal music like Trivium or Dragon Force, here we still get enough speed, unless you're used to listening to metal every day with planar IEMs like PR2, PR3, or S12 Pro, or Timeless. With the EA500LM during the initial adaptation phase, it might feel a bit slow, but the texture remains good.
If you've been using non-planar IEMs lately or haven't been using planar IEMs at all, the EA500LM's single DD still feels quite fast.
So, with the EA500LM, it's enjoyable to listen to any genre. Pop songs sound lively, dangdut or even EDM retains its enjoyable bass without feeling dry or hollow.
Now, if we switch to the Gold Nozzle - Red Ring, the bass quantity increases slightly, the mid-bass becomes thicker, so for Pop, Top 40, or EDM music, it can hit harder, although it won't reach the immersive levels of basshead IEMs. The lower vocals also become thicker here. On the other hand, using the Silver Nozzle with the Black Ring, the bass becomes tighter or thinner but can be quicker.
Here, we need to be careful and pay close attention to the sound signature of our source.
In my experience, when I first received the EA500LM, it was fitted with the Gold Nozzle - Red Ring. When I plugged it into the F.Audio T3, which inherently has smoothing in the upper mid-range and treble areas and has a warm tonality, the EA500LM initially disappointed me a bit. Overall, the tone felt too warm, somewhat muddy, with vocals pushed back and the treble somewhat dulled. This affected not only the tonality but also the technical aspects, such as clarity, separation, and sound staging, all felt somewhat lacking.
On the other hand, when I switched to the Silver Nozzle, whether with the Red-Ring or the Black-Ring, the difference was significant. These two Silver Nozzles are much more compatible with the F.Audio T3 compared to the Gold one.
Conversely, the Gold Nozzle feels best when plugged into other sources like the AM01, Fiio KA13, or even J3 Eline. It sounds best with the KA13. Here, we get bass that's punchier yet tidier and cleaner. The positive impact extends to the overall vocal and treble presentation, which sounds nicer and cleaner here than when plugged into the F.Audio T3 earlier.
*MID & VOCAL*
Regarding the mids and vocals, using the Silver Nozzle - Red Ring, the vocal thickness is just right, positioned well in the center for male vocals, while for female vocals they sound more forward here. When plugged into the F.Audio T3 with the Silver Nozzle - Red Ring, the vocals feel relaxed, fitting, lively, and clean, with clear articulation of lyrics and good dynamics that convey emotion well.
However, when this Silver Nozzle is plugged into the Fiio KA13, it tends to be slightly aggressive in the upper mid-range, and male vocals become somewhat thin, while female vocals become even more pronounced. Sometimes, it can sound shouty and slightly sibilant.
With the Fiio KA13, KZ AM01, or J3 Eline, in my opinion, the best match is with the Gold Nozzle - Red Ring, which makes male vocals thicker, while female vocals and the overall upper mid-range don't become too forward. Using the Gold Nozzle here prevents shoutiness or sibilance.
Instrument sounds in the mid-range have a similar presentation to vocals. Clear, clean, lively, with good clarity. But again, match or synergize the nozzle with the sound signature of the source.
*HIGH / TREBLE*
For the high frequencies or treble, the extension is decent; it has good extension but not overly extended, nor is it truncated. It's just right. The focus is more on the upper midrange to the lower treble. The mid-treble also retains a nice crispness. Instrument sounds in this frequency range, such as the cymbals, focus more on the initial strikes, the crashes or crispness, which feel quite forward.
Here, if we use a warm source with a lot of smoothing like the F.Audio T3, I personally find the Silver Nozzle - Red Ring more suitable. You can also use the Black Ring if you want an even crisper instrument presentation. Because if you use the Gold Nozzle, the EA500LM with the F.Audio T3 will feel muddy, with too much bass bleeding to the lower mid-range, and the vocals will be too recessed.
Conversely, if you pair it with a bright source like the Fiio KA13, the Gold Nozzle feels the most comfortable for listening to any genre. The crispness is just right, not piercing, with very minimal peaks, and still delivers a very clean instrument presentation. Meanwhile, if you use the Silver Nozzle, especially the Black Ring one, the treble can be a bit too forward and quite aggressive.
So, those were the tonal characteristics. It's really beneficial that the EA500LM has detachable nozzles that can be tuned to match our sources better. If your source is warm, use the Silver nozzle; if your source is bright, use the Gold nozzle. Both provide good, clean tonal presentations.
*TECHNICALITY*
In terms of technical performance, what stands out most about the Simgot EA500LM is its clean presentation. The quality of its dynamic driver is very good. No matter which source you plug it into, the presentation remains clean once tuned properly. Furthermore, the cleaner the source, the greater its potential for cleanliness. For example, with these two sources, although both can make the presentation of the LM clean, it's still cleaner with the Fiio KA13 compared to the F.Audio T3 or the two other dongles.
*TIMBRE*
Regarding timbre, the EA500LM isn't the most natural, but it's still good enough to distinguish the sound of each instrument. There are no instruments that sound off, metallic, plasticky, muddy, boxy, or anything like that. Everything is relatively safe.
*SEPARATION, LAYERING & POSITIONING*
For separation, layering, and positioning, considering this is only a single dynamic driver and not a planar one, it's pretty good. Instruments are well separated, layering isn't overlapping, and positioning can be analyzed quite well. It's not better than the EM6L, which has one dynamic driver and four BAs, but the EA500LM is still good.
But also note, don't use the Gold Nozzle with a warm DAC or DAP with lots of smoothing if you want good technical performance.
*RESOLUTION, CLARITY & DETAIL*
Including resolution, clarity, and detail, you'll get good resolution, clarity, and detail with the Silver Nozzle. But be careful, this Silver Nozzle has the potential to make the upper mids and treble aggressive when plugged into a bright DAC or DAP. If you're using a DAC or DAP with a bright sound, it's better to use the Gold Nozzle; it still provides good overall resolution, detail, and clarity, including separation, layering, and positioning.
The detail isn't extremely fine, especially in the treble detail, because the treble extension isn't extremely extended, especially in the airy parts; it's just decent in the EA500LM. Not extremely airy.
*SOUND STAGING & IMAGING*
The sound staging of the EA500LM is wide and spacious, with good depth and height, and the sensation of rotation around the head is quite good. In terms of imaging, it also has good depth, height, and rotation sensation around the head.
*COMPARISON*
For comparison, I won't compare it to the EA500 because I haven't tried it myself yet, so I'll compare it to the EM6L first.
If you're really looking for good technical performance in terms of instrument separation, positioning, and layering, the EM6L feels more luxurious.
But with the EM6L, you won't get the same clean instrument and vocal presentation as with the EA500LM. The details and resolution are better with the EM6L, but both still have similar levels of clarity.
For tonality, I personally tend to prefer the EA500LM with the Gold Nozzle paired with the Fiio KA3. The sub-bass hits deep, the mid-bass punch is sufficient, vocals are clean without thinning out, and the treble has a lively presentation without being aggressive.
At this price point, what else do we have? Maybe the Hidizs MS3. Resolution is indeed better with the Hidizs MS3. Separation and 3D imaging are also slightly better with the MS3. But once again, in terms of the clean instrument presentation given by the drivers, the EA500LM is still better. Tonal-wise, the MS3 has some points of aggressive upper vocals and lower treble.
*CONCLUSION*
Okay, folks, in conclusion, if you're a fan of single dynamic drivers, whether it's single DD or dual DD, at the price of around 1 million, I think the Simgot EA500LM is one of the good choices and safe to pair with whatever source you have. Just adjust it with its detachable nozzles. And I suggest optimizing its potential by pairing it with a good source, especially one with a clean black background and good technical performance, no need for high power.
But if you're really into technical aspects like separation, imaging, and positioning, you might lean more towards the Simgot EM6L or Hidizs MS3.
Okay, peace be upon you, and thank you.

Yeah, finally dropped a few lines here. First time putting my thoughts into words. I'm Kevin from Indonesia. Been doing the YouTube thing on my channel, Alba Project, for about a year.
Here's the link: youtube.com/@AlbaProject
Feel free to check out some reviews I've cooked up for various in-ear monitors from different brands, including KZ, QKZ, Simgot, 7Hz, Tangzu, TRN, CCA, Tanchjim, Moondrop, Sgor, Hidizs, and more. Okay, that's it for my introduction.
SIMGOT EM6L
An In-Ear Monitor packing 1 Dynamic Driver and 4 Balanced Armature Drivers.
Never Let Me Down
Ever since I crossed paths with Simgot, starting with the EW100P series, then cruising over to the EW200, I gotta say, Simgot's been keeping the letdowns at bay. In my neck of the woods, Indonesia, Simgot's become one of those IEMs you're always keeping an eye out for.
And guess what? Simgot just sent over their freshest In-Ear Monitor. Been rocking it for about 2 weeks now, and surprise, surprise, Simgot's still hitting the satisfaction button with their latest gear.
Alright, time to spill the beans on my take for the SIMGOT EM6L.
Price
Simgot is marketed through several online stores with a price tag of $109.99, which translates to around 1.7 million Rupiah in Indonesia, where I'm located.

For an In-Ear Monitor priced at 1.7 million Rupiah, the packaging applied to the Simgot EM6L is considered quite fitting.
With a glossy black box featuring an illustration of a Phoenix, I'm quite satisfied. The back also displays a Frequency Response graph to help understand the sound direction. The configuration of the driver units is clearly illustrated, and additional specifications are provided in four languages: Chinese, English, Japanese, and Korean. Oh, on the front, Simgot also includes the Hi-Res Audio logo in yellow, emphasizing that the unit we're holding is a high-resolution In-Ear Monitor.
What's in the Box
From the packaging, here are the items we get:
- A pair of Simgot EM6L IEMsA cable with a 3.5mm jack, connecting to the drivers using a 2-pin 0.75mm interface, also equipped with a jack cover3 pairs of silicone eartips1 hard caseUser ManualIEM's Look
Simgot EM6L adopts the typical chi-fi design. This time, I see it as an IEM with an elegant yet luxurious design in simplicity.
With a slim physical size, it lacks many indentations or decorations. There's only the Simgot logo on the left side unit and the Phoenix logo on the right side unit. There's a slight touch of metal for the nozzle part. Unfortunately, Simgot didn't add a lip to the smooth nozzle, making it challenging to change eartips. I alternately tried Spinfit CP145, Acoustune AET08, and AET07 on this IEM. Suddenly, AET08 came off and jumped by itself when I placed the IEM on the table.
Build Quality
The entire IEM is wrapped in a glossy black resin shell, matching the color of the packaging box. Unfortunately, fingerprints easily stick to it. Regarding the metal nozzle lacking a lip, I explained that above.
Speaking of the cable quality, I don't find anything exceptional, but I must say that its appearance is quite nice, and I like it.
Then the 3 pairs of eartips, the silicone texture is quite soft with a suitable thickness. I personally prefer using the size S. Larger sizes like M or L make my ears tired quickly.
Fitting
Zero fit issues. Smooth sailing to a comfy position with solid isolation. No complaints here.

SOUND QUALITY
Low / Bass
The low or bass sector in the Simgot EM6L is presented cleanly with a texture that is quite good. The main focus is on the sub-bass. It has a good rumble, with a transient speed that is quite fast, although not as fast as planar drivers like KZ PR2, PR3, or 7Hz Timeless. The mid-bass has a tight thump character, but it's slightly lacking in power to represent a Kick Drum thump and a bit thin for my taste. If it could be a bit thicker, it would be more enjoyable. The bass texture is good, well-controlled, so it doesn't interfere with the vocal area. The most enjoyable aspect of this sector is the sub-bass; its impact can genuinely bring a gust of wind to my eardrums.
Instruments and Vocals in the Mid-range
Vocals and instruments like guitar and piano in the mid-range are presented cleanly, clearly, smoothly, and with minimal peaks. Female vocals sound melodious, sweet, with the right thickness, clear articulation, and very rarely do I encounter sibilance or shoutiness. The positioning is sometimes in the middle, sometimes sounding quite forward but not overwhelming. As for male vocals, they are slightly less thick for my taste, but they still have a clean presentation, good articulation, and clear clarity. The emotion of each singer is also conveyed well. The timbre of the vocals sounds quite natural, unlike the metallic timbre of most balanced armature drivers. The Balanced Armature Driver in the Simgot EM6L excels at executing vocal sounds, making them sound close to natural. However, the distortion sounds from the guitar sometimes appear soft and lack bite.
High / Treble
The high or treble in the Simgot EM6L is presented smoothly but still clean and has good extension. I don't feel any disturbance in high-frequency guitar sounds or violin bowing, nor do aggressive or painful sounds from cymbals and snare drums. Everything sounds safe here. Nevertheless, it still manages to provide good detail and clarity.
Technicalities
Resolution, Clarity, and Detail: EM6L can deliver good and dense resolution, rich in detail, and each note is presented with clear and distinct clarity.
About Sound Staging, this IEM can create a magnificent and spacious stage impression. The 3D effect is quite well depicted, although the depth and height impressions are just sufficient.
The position or direction of the sound from each instrument is relatively easy to analyze. The separation of each instrument is clear, so there is no overlap.
Conclusion
In conclusion, it's no wonder there are many positive impressions circulating about the Simgot EM6L, both on YouTube and audiophile communities on Facebook. The Simgot EM6L brings a Harman-ish tonal but with some re-tuning touches, so the treble area is not as sharp as other harman-tuned IEMs we know. I can listen to music for hours during work without any issues; my ears don't easily get tired with the Simgot EM6L. For those who find the Simgot EW200 too aggressive in the upper vocal or treble areas, I recommend trying the Simgot EM6L.Last edited:
