Reviews by nihalsharma
Hello everyone, and thank you for joining. Today, I am reviewing the Penon Dome, a hybrid IEM with 1DD, 2 Sonion BA drivers, and 1 Knowles BA driver. This unit was sent by Penon for review purposes. I would like to extend my sincere gratitude to them for providing me with the sample. The impressions in this review are in no way influenced. I write what I hear.
Penon is quite a well-known brand in the audiophile community. They have created their own segment. Most of the releases by Penon have been very well received. They have released IEMs with a variety of signatures. One of their latest releases, Quattro, has a very nice fan following. I reviewed Quattro sometime back. I enjoyed the musical and warm nature of the Quattro. Dome is a very different sounding IEM than the Quattro, I’ll try to compare Dome with some other IEMs to give a perspective on what to expect from Dome.
Penon Dome can be bought from here. Link
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. The fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.
Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats, such as price, fit, etc.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Configuration (from the website):
Driver: 3 BA + 1 Dynamic driver hybrid; BA: 1 Knowles for high frequency, 2 Sonion for middle frequency
Dynamic driver type: 10mm PET diaphragm for low frequency
Impedance: 19ohm
Sensitivity: 107dB
Frequency response: 20-20kHz
Passive noise reduction: 26dB
Connector: 2pin 0.78mm
Cable length: 1.2M
Design, build, and fit:
Talking about the packaging, Penon Dome comes in a yellow box with similar packaging as Quattro. There are plenty of accessories inside the box. I really appreciate the variety of ear tips that Penon has offered with the Dome. There is this same blue case present inside, which Penon offers with many other IEMs.
The shells on Dome are handmade in medical-grade resin. It is very lightweight and quite easy on the ears. The shells do not exert any pressure, even in longer sessions. The nozzle is of a standard size, neither too short nor too long. For reducing pressure buildup, there is a vent present. I did not encounter any driver flex with Dome.
There are plenty of ear tips that comes with Dome. These tips are of different sizes and I am sure one would not need to look for different tips. Since the IEMs have a very nice build, they go easily with various types of tips. I paired the Dome with Spinfit W1, Azla SednaLight (MS), both of which go really well with the IEM. Azla adds some openness in the sound and is my preferred ear tips on Dome. I got a very decent fit with Tangzu Sancai balanced tips too.
In terms of isolation, these IEMs are above average. They block a good amount of outside noise. I would not take it out in public, though. With a good-fitting ear tip, the isolation is quite decent.
Sound Analysis:
For the sound impression, most of the time I pair Dome with my Lotoo Paw Gold Touch dap and, occasionally, with Earmen Angel. I paired the IEMs with stock cables (and some third-party cables too) and Spinfit W1 ear tips, size S.
Dome is a warm musical set to begin with. The sound has a good amount of bass, beautiful, lush, warm mids, and a treble that is non-offensive. The sound is all about sweetness. This sound prioritizes musicality over technical precision. However, in no way are the technicalities compromised.
The bass on Dome is rich and warm and has good thickness. It has a very good impact and plenty of quantity, with good layering and texture. However, it's not the most refined bass; it is more about adding to the musicality. There is a decent subbass presence, and it's plenty when called for. The bassline from something like a bass guitar is quite pleasant. The bass on Dome is not boomy or bloated in nature, or the kind of bass that sort of eclipses the higher frequencies. This bass is quite different than that of Quattro, where there is more of an analogous character and the bass envelopes the higher frequencies.
The mids on Dome are all about warmth and sweetness. There is a very decent resolution and clarity in the midrange. The lower midrange has a decent body to it. The upper mids are well extended and maintain a decent amount of energy. At no point did I find it to be peaky or extra sharp. I find the mids quite forward. Vocals have good texture. There is loads of sweetness in the female vocals. Midrange instruments have a very sweet and lifelike presentation. I prefer this midrange over Quattro.
Treble on Dome is not quite airy, but the details and energy are decent. Dome is good for people who don't want any unwanted sharpness and want a safer treble profile. This treble may not be well appreciated by trebleheads, though. I find it decent, as it really makes a case for longer sessions.
On the technical front, the soundstage is quite decent, with a good width and decent depth. There is a good separation of instruments; however, for busy musical sequences such as the metal genre, there is some lacking. Imaging is just decent, and there is nothing much to complain about given the price of this IEM. In terms of resolution, I would say there is a bit of a step back as well. I would have loved cleaner sound from Dome, but I think that's asking a lot from the IEM.
Source Pairing:
Dome is quite easy to drive. It does not ask for a lot of power. It can be easily paired with smartphones, too. I tried Dome with three different sources. The LPGT has a very decent synergy with the Dome. The bass has a good body, especially in the subbass region, which has a decent presence. In the mids, the LPGT adds nice warmth.
I quite liked the pairing with Quloos MUB1 too. There is such a sweetness in the sound of this pair; I absolutely love it. MUB1 is very resolving for a DAC/amp of it's size.
With Earmen Angel, I did not find the Dome pairing well, so I assume Dome does not need extra power. The dynamics are better at lower levels of power. With Angel, it just sounds off.
Cable Pairing:
The only thing I found lacking with the Dome is it's cable. While it gets the job done, I believe it holds back the Dome's full potential. I tried pairing it with some aftermarket cables, and here is what I found. It's clear: the Dome doesn't demand expensive cables to reveal its nuances. Even a modest cable can enhance the Dome's performance.
With the Letshuoer L-R Nebula Cable:
Letshuoer released this cable just a while ago. The Nebula cable exhibits the essence of a traditional copper cable. It enriches the lower frequencies, infusing them with added depth and character. The midrange also gets an improvement with some added richness. The overall resolution and clarity in the midrange are better with this cable. The stage is more intimate, and things come a lot more forward. A little bit of addition in treble energy would be really great, but the cable does not add much on that front.
With Aes Harmony from Gladiator Cable:
This cable features 6N pure Up-OCC copper wire with a thick silver plating. The configuration helps in maintaining a balance between warmth and detailing. The soundstage is a lot better with this cable, which spreads further in all directions. There is a nice refinement in the sound. The lows sound more balanced, with an evenness in the sub-bass and mid-bass. The mids have better resolution, and the cable adds a bit of crispiness. This cable does not add as much warmth as the Nebula does.
Comparisons:
With Kinera Freya2.0:
Freya2 has a similar configuration, equipped with a hybrid single 7mm dynamic and 3 BA drivers. Priced at $269 SRP this is one of Kinera’s midrange IEMs. In terms of overall design and presentation, we all know Kinera just goes over the top. Freya2 looks a lot more beautifully built and designed than the Dome. The cable that comes with it is a modular one and has a better build than that on the Dome.
However, it is the sound where Freya2 lacks too much. I do not think there is any attribute where Freya2 excels. Dome is a lot more musical than the gloomy characteristics of Freya2. In terms of technicalities too, Dome has quite an edge. It has a better soundstage and sounds very open compared to Freya2.
With Rose Technics QT-X:
Rose Technics QT-X is equipped with 1 dynamic driver and 6 BA drivers. The one I had tried was a value pack, which comes with a small dongle dac/amp too, making the whole package quite versatile. In terms of build and packaging, QT-X has an edge. The shells are lightweight and fit really well. The cable on it is a better one than the one on Dome.
In terms of sound, QT-X is tough competition. I love the bass on QT-X. The lows are quite deep, and the subbass has a good body. Dome has more quantity to it's bass but is not as refined. The mids, however, are more musical in nature on Dome. For some, the mids on QT-X may come a bit thin. In the upper frequency range, QT-X has a better presentation. There is more energy and better extension in the treble region on QT-X.
In terms of technicalities, QT-X gives a good fight too. The soundstage is decent on both of these IEMs. QT-X does better in terms of resolution. It has a cleaner sound. The notes are clean and crisp. I would say QT-X may have an edge. If at all we have to choose between the two IEMs, it would be more of a musicality vs. technicality thing.
With Penon Quattro:
The highly appreciated Penon Quattro is equipped with 4 dynamic drivers. It is priced at $399. The packaging on Quattro is nearly the same as with Dome. In terms of build quality, Quattro has an edge. Its shells are better built and are harder and tougher. The cable on Quattro is better than that on Dome. I really wish Penon provided this same cable, but that may add to the cost.
In terms of sound, these two sets have quite different characteristics, but they maintain the same philosophy: musicality over technicality. Quattro has a very distinct, warm signature and a coloured sound. There is a bass boost all around. This thick bass predominantly defines the signature of these IEMs. It's like everything sounds within a layer of bass. Dome, on the other hand, has a faster bass and a lower volume.
In mids, there is a lot of bass bleeding into mids on Quattro, while on Dome, the mids stay quite clean and there is no bass intrusion. In the upper mids region, there is a hint of shoutyness on Quattro, while Dome does not have any such thing. The treble on Quattro is darker than on Dome.
I think it's hard to compare Quattro with other IEMs. For the general public, Dome has a more likeable tuning, while Quattro has a very different tuning, which people can align with or may not.
Conclusion:
It is quite evident that Penon went the musical route while developing the Dome. They must have some special sauce to pull off such a musical IEM. The bass and mids on Dome strike a very nice balance. The bass never overwhelms yet maintains a satisfying depth, while the mids retain their sweetness, giving these IEMs a vibrant and natural quality sound. If someone is looking for a musical set without sacrificing a lot of technical aspects, Dome can be an easy recommendation. With both the Quattro and Dome boasting distinct yet appealing sound signatures, it's evident that Penon has a knack for finely tuning their IEMs. I must say I am very hopeful of what future releases they have in line. I would rate these IEMs at 4.5/5.

Quloos, a well-known Chinese brand, is celebrated for its wide array of high-quality audio products. My introduction to the brand came through MUB1, a dac/amp unit. Prior to experiencing this little wonder firsthand, I came across commendations for this compact device and decided to dig deeper into both the product and the brand itself. Among their notable offerings from the brand is the QA390LE, which has also received acclaim for its exceptional quality from various people.
Concept Kart, a local online store in India, sent me the MUB1 for an audition. MUB1 sells for nearly 500 USD. It can be bought here. Link

Product Features:
MUB1 boasts a plethora of features, rendering it an exceedingly valuable device. It encompasses all the essential functionalities one could think of within its price range. To begin with, it harnesses the power of four CS43131 DAC chipsets, for delivering exceptional sound quality characterized by high resolution and refined tones, along with an impressive signal-to-noise ratio.
Inputs: There is a USB type-C data source where you can connect your devices for listening. The other USB-C port is for charging. It also takes data input via Bluetooth, supporting the 5.0 BT protocol. The BT connection uses some advanced features to stream with decent sound. The BT connection is quite strong and does not drop.
Gains: There are 4 types of gain modes. Low, Medium, High, and Super High gain modes. For iems, high gain mode is more than enough. One can use super high gain with more power-hungry headphones as the output is nearly 3–4 times that of high gain.
Filters: MUB1 offers five different types of filters. While these filters have quite subtle differences, it's good to have options. I used the MUB1 mostly with the NOS filter. Its the most relaxed of all.
Outputs: There is a 3.5mm and a 4.4mm balanced output. The 4.4 balanced output can be set to line out. There is a 3.5 mm optical or coaxial SPDIF digital output too.
Design: MUB1 is quite compact and has a very sleek design factor. It is very lightweight, and its dimension is not an issue when carrying a smartphone. The build feels quite premium, and the device gives a good, solid feel when you hold it. All the functional buttons are on the right side of the device, and the lower side has input and output ports.
Battery: There are separate charging and data slots. For charging, it takes a 5V/2A power supply. The battery life is very decent and can go up to nearly 8 hours on the balanced output. I could not time the battery life, though. To give a good and long life to the battery, there is an option where, when you connect the device to a charger, you can bypass the battery and power the MUB1 directly from the charging port.
Sound Analysis:
MUB1 is a little powerhouse with a very impressive sound and great tonality. The sound is warm and smooth, with some decent bass presence, a sweet midrange, and controlled highs.
The bass on MUB1 is quite decent. Its well layered and has a good texture to it. The subbass has a good body and depth. The bass is tight and precise, with a good impact, and does not intrude on the higher frequencies.
The midrange has a very natural feel, and there is a nice tonal weight to it. The mids are sweet, as per my liking, and the resolution is very decent. Both male and female vocals have good texture and sound quite full. Midrange instruments like piano, string, etc. have decent weight and extension. The upper mids have a good amount of energy and do not get shouty at all. There is no thinness in the upper mids.
The upper frequency is quite controlled and smooth. There is no sharpness or unwanted peakiness, making it ideal for longer sessions. There is good detailing and extension. However, the sense of airiness is not quite pronounced.
In terms of technical aspects, MUB1 performs above average. The soundstage is not as wide but is not even intimate. The depth is quite decent. The separation of instruments in complex musical passages is very decent, and there is no congestion.
Comparisons and pairings:
The only other similar device I could compare the MUB1 with was the Earmen Angel. Angel is more powerful than the MUB1. It hosts an ESS DAC, ES9038Q2M chip. Angel has a neutral sound signature with a hint of brightness. The soundstage on Angel is wider than that of MUB1, and the depth is almost similar.
The natural and organic tonality of MUB1 is more to my liking than the analytical and rather cold signature of Angel. Angel pairs well with warmer iems and adds a sense of airiness. Angel can drive some power-hungry headphones and iems quite well where MUB1 can lack a bit. Angel does not have Bluetooth. Also, MUB1 has buttons to pause, play, and skip tracks, which are not there in Angel. So, in terms of usability, MUB1 can appeal to a lot of people.
Pair up:
64Audio Fourte: I absolutely love how MUB1 handles the Fourte. Its controlled and refined highs create a perfect synergy with the Fourte's nearly-bright character. Mids sound sweeter on the MUB1. The mids are rendered with a delightful sweetness on the MUB1. Personally, I refrain from using the Fourte with Angel as it tends to increase its brightness. With Fourte, there is a slight static hiss likely due to Angel's higher power output. However, I really wish that headstage was a bit better with the MUB1. I found it limiting the true potential of Fourte. I used the NOS filter for the Fourte, which dealt with the upper frequencies the best.
Kinera Verdandi: Verdandi is a power-hungry iem and scales quite a bit with a powerful amp section. MUB1 handles the Verdandi really well; however, the Angel does more justice to it. On Angel, the Verdandi sounds more open, and the headstage is better, thus creating a more expansive audio experience. The output on Angel shows a good sense of airiness, with improved bass impact compared to MUB1.
Among the less power-hungry iems, my preference leans strongly towards MUB1. Its natural tonality significantly enhances its musical character. One reason to avoid Angel with sensitive iems is because of the static hiss in the background. Angel performs really well with iems having a warm signature and higher power demands; otherwise, it tends to sound overly analytical in many instances.
Conclusion:
The MUB1 stands out as an exceptional device, offering a comprehensive range of features within its compact form. It sounds amazing. It has a great battery life. It is powerful enough to fire up most of the iems and decent-sized cans. MUB1 effectively renders any potential use case for a dongle, especially the more expensive ones, obsolete. While its price may be higher compared to most dongles, its unparalleled performance justifies the investment. In my opinion, no other dongle can match the exceptional sound quality of the MUB1. It can also give a good fight to some more powerful dac/amps. I cannot find anything that is missing with the MUB1. It gets a solid recommendation from me. A true 5/5 device.

To begin with, it harnesses the power of four CS43131 DAC chipsets, for delivering exceptional sound quality characterized by high resolution and refined tones, along with an impressive signal-to-noise ratio.
Inputs: There is a USB type-C data source where you can connect your devices for listening. The other USB-C port is for charging. It also takes data input via Bluetooth, supporting the 5.0 BT protocol. The BT connection uses some advanced features to stream with decent sound. The BT connection is quite strong and does not drop.
Gains: There are 4 types of gain modes. Low, Medium, High, and Super High gain modes. For iems, high gain mode is more than enough. One can use super high gain with more power-hungry headphones as the output is nearly 3–4 times that of high gain.
Filters: MUB1 offers five different types of filters. While these filters have quite subtle differences, it's good to have options. I used the MUB1 mostly with the NOS filter. Its the most relaxed of all.
Outputs: There is a 3.5mm and a 4.4mm balanced output. The 4.4 balanced output can be set to line out. There is a 3.5 mm optical or coaxial SPDIF digital output too.
Design: MUB1 is quite compact and has a very sleek design factor. It is very lightweight, and its dimension is not an issue when carrying a smartphone. The build feels quite premium, and the device gives a good, solid feel when you hold it. All the functional buttons are on the right side of the device, and the lower side has input and output ports.
Battery: There are separate charging and data slots. For charging, it takes a 5V/2A power supply. The battery life is very decent and can go up to nearly 8 hours on the balanced output. I could not time the battery life, though. To give a good and long life to the battery, there is an option where, when you connect the device to a charger, you can bypass the battery and power the MUB1 directly from the charging port.
Sound Analysis:
MUB1 is a little powerhouse with a very impressive sound and great tonality. The sound is warm and smooth, with some decent bass presence, a sweet midrange, and controlled highs.
The bass on MUB1 is quite decent. Its well layered and has a good texture to it. The subbass has a good body and depth. The bass is tight and precise, with a good impact, and does not intrude on the higher frequencies.
The midrange has a very natural feel, and there is a nice tonal weight to it. The mids are sweet, as per my liking, and the resolution is very decent. Both male and female vocals have good texture and sound quite full. Midrange instruments like piano, string, etc. have decent weight and extension. The upper mids have a good amount of energy and do not get shouty at all. There is no thinness in the upper mids.
The upper frequency is quite controlled and smooth. There is no sharpness or unwanted peakiness, making it ideal for longer sessions. There is good detailing and extension. However, the sense of airiness is not quite pronounced.
In terms of technical aspects, MUB1 performs above average. The soundstage is not as wide but is not even intimate. The depth is quite decent. The separation of instruments in complex musical passages is very decent, and there is no congestion.
Comparisons and pairings:
The only other similar device I could compare the MUB1 with was the Earmen Angel. Angel is more powerful than the MUB1. It hosts an ESS DAC, ES9038Q2M chip. Angel has a neutral sound signature with a hint of brightness. The soundstage on Angel is wider than that of MUB1, and the depth is almost similar.
The natural and organic tonality of MUB1 is more to my liking than the analytical and rather cold signature of Angel. Angel pairs well with warmer iems and adds a sense of airiness. Angel can drive some power-hungry headphones and iems quite well where MUB1 can lack a bit. Angel does not have Bluetooth. Also, MUB1 has buttons to pause, play, and skip tracks, which are not there in Angel. So, in terms of usability, MUB1 can appeal to a lot of people.
Pair up:
64Audio Fourte: I absolutely love how MUB1 handles the Fourte. Its controlled and refined highs create a perfect synergy with the Fourte's nearly-bright character. Mids sound sweeter on the MUB1. The mids are rendered with a delightful sweetness on the MUB1. Personally, I refrain from using the Fourte with Angel as it tends to increase its brightness. With Fourte, there is a slight static hiss likely due to Angel's higher power output. However, I really wish that headstage was a bit better with the MUB1. I found it limiting the true potential of Fourte. I used the NOS filter for the Fourte, which dealt with the upper frequencies the best.
Kinera Verdandi: Verdandi is a power-hungry iem and scales quite a bit with a powerful amp section. MUB1 handles the Verdandi really well; however, the Angel does more justice to it. On Angel, the Verdandi sounds more open, and the headstage is better, thus creating a more expansive audio experience. The output on Angel shows a good sense of airiness, with improved bass impact compared to MUB1.
Among the less power-hungry iems, my preference leans strongly towards MUB1. Its natural tonality significantly enhances its musical character. One reason to avoid Angel with sensitive iems is because of the static hiss in the background. Angel performs really well with iems having a warm signature and higher power demands; otherwise, it tends to sound overly analytical in many instances.
Conclusion:
The MUB1 stands out as an exceptional device, offering a comprehensive range of features within its compact form. It sounds amazing. It has a great battery life. It is powerful enough to fire up most of the iems and decent-sized cans. MUB1 effectively renders any potential use case for a dongle, especially the more expensive ones, obsolete. While its price may be higher compared to most dongles, its unparalleled performance justifies the investment. In my opinion, no other dongle can match the exceptional sound quality of the MUB1. It can also give a good fight to some more powerful dac/amps. I cannot find anything that is missing with the MUB1. It gets a solid recommendation from me. A true 5/5 device.

Great review, very curious about it compared to shanling H5/Fiio Q15 and DC elite (smaller format without battery)
NiceHCK, established in 2015, has become a respected name in the budget audiophile market. They offer a diverse array of products, such as iems, earbuds, and upgrade cables. Known for their commitment to quality, NiceHCK delivers top-notch performance at reasonable prices. Their products boast excellent sound performance, durable construction, and attractive pricing. Among their successful releases are the NX7 Pro IEMs, EBX21 Earbuds, and the flagship Top Guy IEMs.
The NiceHCK F1 Pro was on my radar as a potential pair of iems to try out. Having previously experienced a variety of budget planar iems, including the Letshuoer S15, Kefine Klanar, Hidizs MP145, and Shozy P20, I felt like I had already reviewed some of the best offerings in this category. However, the buzz surrounding the F1 Pro persisted, and I was fortunate enough to receive a pair from NiceHCK for trying out. Overall, the F1 Pro intrigued me with its unique combination of features, and I was eager to see how it stacked up against other planar IEMs in its price range. I'm thankful for the opportunity, and it's important to note that my opinions remain unbiased despite the source of the product.
F1 Pro is available here: Ali Express Link and on Amazon here: Link
It is available to buy here in India here: Link. It can be bought from Hifigo: Link
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. The fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.
Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats, such as price, fit, etc.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Configuration (from the website):
Design, build, and fit:
These iems have a metallic body and a solid construction that ensures durability and longevity. They are lightweight. Their compact size and ergonomic design make them comfortable to use for extended periods of time.
The cable is of good quality and nicely finished; it comes with a 2-pin connection and a 4.4mm adapter included. The case included is built well and feels durable too. The white color of the cable pairs well with the blue color of the iem shells.
There is a decent set of eartips that come with these iems. I tried them with some other tips as well: Spinfit W1 and Azla SendnaFit Light eartips. Both of these tips go really well. The nozzle is average length; a tip with a long stem can fit well too. This nozzle length can accommodate quite a lot of different eartips, so fit is not much of an issue on these iem.
I find the isolation in these iems above average. With the right choice of good fitting eartips, it can easily block some level of noise from outside. In my time with these iems, I did not find any driver flex issues. In my experience, I encountered no issues of pressure buildup during my time with these iems.
Sound Analysis:
F1 Pro turned out to be a nice surprise. The sound has a decent balance of fun and musicality. It has a V-shaped sound profile.
The bass department excels on these iems. The bass has a very solid impact and a decent punch. The subbass has a good presence. The quality of bass is quite good, with decent layering and texturing. The bass, though having a nice quantity, does not bleed into the mids and leaves it clean.
The midrange is not as forward as to my liking. The lower midrange is recessed, while the upper midrange still manages to come out in the front. While the mids are not a strong point for these iems, I find the weight in the midrange quite pleasing. The upper midrange is tuned really well, devoid of harshness and fatiguing peaks. However, there is extra energy and some instances of thinness in the upper mids region.
These iems handle treble really well. The treble is smooth, extends quite well, maintains energy, and has a nice level of detail. There are instances of sibilance and slight peakiness, which is not a regular thing. I would term it a borderline brightness for sensitive people.
On the technical front, these iems are decent. The soundstage has an average width, and the depth is quite decent. There is decent spaciousness. There is great clarity in the sound, and things come out quite detailed. There is decent instrument separation as well, which is evident even on tracks where there are complex musical passages. From the point of view of the planar driver, I do not find the notorious metallic glare to be prominent.
In terms of driveability, these iems do need a bit of extra juice to shine. Though they are easy to drive, they need powerful sources to show their full potential. They pair well with both the sources I tried, LPGT and Earmen Angel. I find sound to have better dynamics from a more powerful source.
Comparisons:
With Hidizs MP145 (139 usd):
MP145 has an extraordinary soundstage, a very vivid out-of-the-head experience. Technically, MP145 is ahead of F1 Pro
The bass is on the leaner side of MP145. Also, the planar timbre is not very pronounced on these, but the timbre and tonality on the F1 Pro are definitely better. MP145 is the brighter of the two.
The size of the MP145 shells is massive, so the F1 Pro has a much better fit and is lighter of the two. I find the cable on F1 Pro to be better.
With Kefine Klanar (90 USD):
In terms of fit, these iems are quite comfortable. They are both light and not quite big.
I love the bass on Klanar, which goes deep and has enough impact. However, F1 Pro has a better bass body and more impact. The subbass on F1 Pro goes deeper.
Technically, Klanar does not have the blackest background and cleanest sound, and there is a bit of a hazy presentation. F1 Pro has better resolution. I find F1 Pro to be more musical too.
With Shozy P20 ($139 USD):
In terms of fit these iems are quite comfortable. They both are light and not quite big. P20 has more resemblance with the Klanar in terms of shape and size.
In terms of bass, the P20 has more midbass impact, and the subbass does not go deep enough. F1 Pro has more enjoyable bass.
In terms of technicality, F1 Pro excels with better imaging and more depth in the soundstage.
Additionally, P20 has a more pronounced metallic timbre.
Conclusion:
F1 Pro, though one of the many planar iems on the market, is not just another planar iem. It stands out from others in its category by delivering a sound profile that is a balance of both fun and musicality. The bass is promising; there are nice technical aspects to these iems and these all set these iems apart from other planar iems. This product, as a whole package, offers great value for money. Though certainly not the best, it surely is an easy recommendation in the sub-100 USD category. I rate it 4/5

Founded in 2012, Rose Technics has a good presence in the audiophile industry in China. With a diverse range of products, including in-ear monitors, true wireless earphones, and headphones, Rose Technics has garnered praise from enthusiasts. They are quite confident about tuning of their iems, some of which are done by notable people coming from companies such as Sony, Fostex, etc. I have tried a few other iems from their lineup and was really interested in trying the top-line iems.
I got a chance to try out the QT-X iems, an iem from their line-up equipped with 1 dynamic driver and 6 BA drivers. It's available to buy on Concept Kart in India here: link.
Alternatively, it is available here on the Rose website: Link
You also can get a pair on the AliExpress Store: Link

Design, build, and fit:
I really appreciate the design of these iems; they are lightweight and well-built. The material feels durable, and the shape of the shells provides a comfortable fit for longer listening sessions. The cable is of good quality, with a 2-pin connection and a 4.4mm adapter included. It's also nicely finished with a fabric sleeve. The case included with these IEMs is of high quality and feels well-built, with good materials for the price. Overall, they have included enough accessories inside the box.
Additionally, there is a vent present on these IEMs to minimise pressure buildup. I haven't experienced any pressure or driver flex issues during my time with them.
The iems have slightly smaller nozzles, and wider than usual ear tips can fit well with them. The tips that come with the package are ample and fit really well on these iems. However, I tried them on Azla Sedna Light eartips, which fit really well.
Sound Analysis:
These iems have a sound that is quite satisfactory. The sound profile is near-bright, with a good emphasis on bass.
Bass stands out as a highlight on these iems. The lows are quite deep, and the subbass has a good body. There is a noticeable subbass rumble, which makes the bass a lot more enjoyable. In terms of bass layering and texture, these iems do really well. Midbass is well implemented, not giving a sense of being scooped out, and has a satisfactory quantity. There is no midbass bleeding into the midrange, and the midrange comes across clean.
Mids are neither too forward nor pushed back. These iems maintain sweetness in the midrange, but I find the mids on the thinner side. It has crisp mids and is good in terms of resolution. The lower mids have good weight, though. The thinness (not much) is more in the upper midrange.
Treble on these iems is done quite well. This region has a good amount of energy and extends really well. The micro-details are well presented. This treble is not harsh or sibilant, but it can come across as bordering sharp for some people.
On the technical front, these iems are really capable. Soundstage has a decent width and spreads far and wide. Imaging is good, and one can accurately position instruments and their placements. The resolution and clarity are very impressive too. The notes sound clean and crisp. I think for an iem of this price, the technicalities are more than impressive.

QT-X is quite easy to drive and be easily driven even with a dongle and a mobile phone. With a good source, the sound is open and the resolution enhances a bit.
RZ-500 portable dac/amp:
The inclusion of this dac/amp is more than impressive. It features the flagship ES9038Q2M DAC & ESS9603Q amp chip. The sound is as good as other dongles on the market, which are available for about 100 USD. It comes with a USB-C cable to connect to PCs and mobile phones. I, however, had issues connecting it to my iPhone and could not use this dongle on it. There are a couple of other issues, such as the non-inclusion of the volume button on the dongle, which may limit the use-case for this dongle compared to others. However, it is a really standout feature, and I have not seen any other brands go this way.
Conclusion:
In the crowded market of budget to mid-fi iems (less than 500 USD), these iems offer quite a fresh approach. They stray away from the typical tuning that most of these iems have and give a nice sound quality, especially the nice bass on it. The value pack is a nice welcome for the people and gives immense value for money. All in all, these iems are a decent pair and get an easy recommendation from me.

These look really nice bhai. Hope to hear these soon.
Hello everyone, and thank you for joining me. Today, I'll be reviewing the highly-praised single-DD driver iems, Nightjar Acoustics Singularity. These iems have been widely praised in the community. Nightjar released the first batch of iems in July 2023, and they sold out very soon. There have been more batch releases since then. I had the opportunity to borrow these IEMs from a friend for a few days, and it's worth noting that they had been used extensively before I received them, ensuring they were properly burned in. All these things I am going to mention in this review are totally my thoughts and not influenced by anything.

Singularity is a work of art. From the box to accessories to the iems and cable, everything speaks highly of the craftsmanship that Nightjar has put in. The bamboo box in which these iems come is so beautiful and special. Then comes the beautiful metal case, which has a very nice finish with ample space inside. There is a very decent collection of eartips, notably the Divinus Velvet Eartips, which also come with these iems.
The cable is something very special again, which is priced at 500 USD, and it pairs very well with the iems too. It's on a thinner side and tangles easily, though. I would have preferred it just a bit stiffer.
The iems are quite small, having a metal body that feels really sturdy. The nozzle lies on the shorter side and is angled slightly. Some people may have some fit issues. The eartip selection is important, as I felt it pairs well with some eartips with solid insertion to hold the iems in the ear properly. I paired them with the Azla SednaEarfit Light eartips, which give a proper fit with a decent amount of isolation. Notably, these tips also open up these iems more than the Divinus Velvet tips. Additionally, the Coreir brass tips help open up the sound as they give extra energy to the upper mids and treble region.
Additionally, there is a vent present on the iems which mitigates pressure buildup. I encountered no issues of pressure buildup during my time with them. I also never encountered any driver flex in these iems.
Sound Analysis:
Singularity boasts a highly musical and timbre-perfect sound. The sound has a warm signature that is very natural and rich in tonality, something that can align with everyone's preferences. There is a very good amount of bass, some great mids and a very coherent sound, which makes it quite pleasant. The smaller shells and non-fatiguing nature of sound help with long sessions.
Bass:
The bass is quite special on these iems. There is speed, impact, and a powerful bass, which goes really deep. The quantity is quite massive for a single DD iem. It's not a basshead level of bass, but there is surely a good amount of bass there, which can satisfy someone's hunger. There is a boosted bass, so this bass may perceived as not very crisp and precise, but it fits well in regards to a DD bass definition.
There is no bass bleeding into the mids, but the boosted bass does add to the overall richness in the sound. There is a noticeable subbass rumble, which makes the bass a lot more enjoyable. One good thing is that despite the heavy bass, there is no listening fatigue as I find with some other bass-heavy iems. This bass is just the right amount, quite enjoyable, a pure bliss. I find it quite incredible.
Mids:
The mids on Singularity are very special. They are sweet and natural, perfectly positioned—neither far behind nor too upfront. Mids have good weight and gains from the lower end, especially the lower mids. The vocals are rich. Both male and female vocals are quite open and lush.
The string instruments also sound very rich. The upper mids are quite controlled, and the extension of the string instruments is very smooth and pleasant with enough body. It does not have any sharpness up top, which makes it quite non-fatiguing to listen to.
Treble:
The treble on these iems is not quite a highlight. It lacks a bit of energy and air in this frequency range, resulting in a more laid-back and relaxed treble response. I am not much of a treble head so this quantity is just enough to me. Importantly, there's an absence of undesirable sharpness and sibilance, making these IEMs well-tuned and safe in that regard. It's worth noting that, despite the robust bass, it doesn't overshadow the treble, maintaining a balanced and clear audio profile without any sense of darkness.
The selection of ear tips can significantly impact the perception of treble. For a better treble experience, the Coreir Brass tips are the ideal choice, as they add a subtle boost of energy and openness to the upper frequencies. The sound dispersion is notably improved when using these tips.
Source Synergy:
Singularity is quite easy to drive. It has a good synergy with the sources I tried, LPGT and Earmen Angel. However, to my surprise, the Angel has a better synergy with these iems than the LPGT. Angel has a slightly bright profile and is quite powerful, both of which are added advantages for the IEMs. Angel adds a bit to the missing treble airiness in Singularity. The sound is more open and spacious, too. I absolutely liked their pairing with Angel. One thing to add is that these iems open up quite a lot with additional power. Paired with the Aroma A100TB amp, they opened up a lot with a massive, larger-than-life-like sound.
With the Astell&Kern SP3000, these iems sound quite open, as the dap adds a lot to the soundstage. The pairing with this dap is better than with the LPGT.
Cable pairing:
The included cable with these iems is truly exceptional, and I believe it requires no alterations or enhancements. Nightjar also manufactures some good-quality cables, and they have demonstrated their cable expertise with these iems, ensuring an optimal pairing. The default cable exhibits outstanding synergy, and its market value of 525 USD signifies its superiority over cables offered by many other iems manufacturers.
Technicalities:
The soundstage on Singularity is above average, if not very impressive. There is a good sense of spaciousness in the sound, and with some powerful sources, there is quite an improvement, and the stage spreads out far and wide. Imaging on these iems is quite nice, and you can position instruments easily. The resolution and clarity are very impressive too. The notes sound clean and crisp. I think for an iem of this price, the technicalities are more than impressive.
Comparision:
Sennheiser IE900:
IE900 is another much-respected single-DD iem. I find both of them equally good fitting. IE900 is weightless and simply disappears in the ears. With the right eartips, they stick quite nicely and easily inside the ears. Initially, while using the IE900, I had this sensation of the iems popping out quite often because I did not have the best-fitting eartips on it.
Both of these iems have different sound flavors to offer. Singularity has clearly a lot more bass (boom) than the IE900. IE900 has a good amount of bass but is not as overwhelming as Singularity. It's bass is crisp and precise. It has more energetic tuning with some spice up top. Mids and treble are more relaxed on Singularity.
Softear Twilight:
Twilight is another great single-DD iem. It boasts a timbre-perfect sound signature. Though it looks a bit bigger than Singularity, thanks to its super lightweight design, it's quite easy to use. The shape, though very unorthodox, does not bother me much.
Both of these iems are quite similar in their sound presentation. They have an almost similar technical presentation too. The big difference is obvious with the huge bass impact Singularity has. Mids and treble are equally relaxed on both of these iems. With the right amount of bass on the Twilight and more forward mids, as well as the significant price difference, it becomes tough to pick a winner between the two.
Conclusion:
When I tried the Sony IER-Z1R, it almost reminded me of Singularity. The sounds on these two are quite different, but somehow I related a few things. The bass on both of these iems is too good and equally satisfying, and they both are very musical iems. And for the people who have a fit issue with the Z1R, they can really find peace with the Singularity and not miss much.
To be honest, this iem has its own league. It stands out in the crowd of single DD iems with its massive bass and a very pleasant timbre. It feels like it has been tuned and designed following a rule book, keeping fun aspects in mind. It does not sound like a totl killer, nor will it give you a super wow kick in the beginning. It will grow on you. You can wear them comfortably for hours without any fatigue, which is what I really like about them. The overall package provides a very satisfying ownership experience. These iems have everything to be one's favorite. It's quite impressive of Nightjar to build something like Singularity, which gives a good insight into what one can expect from future releases. I rate these iem 5/5.
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. The fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.
Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats, such as price, fit, etc.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.

I'm having fomo for the Duality over the Singularity when that comes out X'D
Hello everyone, and thank you for joining me. Today, I'll be reviewing the highly-discussed Penon Quattro in-ear monitors (IEMs). I had the opportunity to borrow these IEMs from a friend for a few days, and it's worth noting that they had been used extensively before I received them, ensuring they were properly burnt-in. This is the first time I have tried a Penon iem. I was quite excited to check out what a 4DD combination sounds like. There was quite a lot of exceitemnt before it's release. There are very few iems with such configuration, one notable contender being the Oriolus Monachaa. The Monachaa has also received a fair amount of praise from those who have tried it, but the cost is a big problem there. In contrast, the Penon Quattro, priced at $400, positions itself as a more budget-friendly option.

Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Configuration:
Quattro has four dynamic drivers with different specifications. It uses an independent 3-way crossover and a 3-independent conduit design for better layering performance. Here is how these different drivers handle different frequency ranges:
1 x 6mm custom dynamic driver for High frequency
1 x 8mm graphene diaphragm for Medium frequency
2 x 10mm composite diaphragm for Low frequency
The impedance is marked at 16 ohms, and the sensitivity is 100 dB. These iems need a lot of power to shine.
Design, build and fit:
In the first look, Quattro looks really nice. The shells are handmade and they are lightweight and well-built. I find it quite comfortable enough for long usage. The nozzle on the iems is on the wider side. I find a wide-bore tips to best suit to these iems. Azla SednaFit light is my usual go-to tips for wide and big nozzles. With these iems, tips selcetion is quite important as they may sound quite constrianed and muffled on a lot of tips. I suggest to try out every possible tips to find which sounds most open.
Additionally, there is a vent present on the iems which mitigate pressure buildup. I encountered no issues of pressure buildup during my time with them. I also never encountered any driver flex in these iems.
The package is really nice in the sense it ticks all the boxes. There is nothing more you'd ask for. The addition of leather pouch is qutie well thought. It comes with 9 pairs of silicone eartips catering to various . The blue cable pairs quite aesthetically. Overall, the unboxing and initial usage experience are highly satisfactory, quite aligned with the price point.
Sound Analysis:
Quattro has a very distinct, warm signature and a coloured sound. This is how these iems have been tuned, deviating from a usual standard tuning. Everything on these iems screams: warm, warm, more warm. Under this much warmth, there is a lot of rich musicality. There is a bass boost all around. This thick bass predominantly defines the signature of these iems. It's like everything sounds within a layer of bass. Some people may really relate to this analogous sound, and some may not. Let's dissect the sound even further.
Bass:
The bass on these iems is dominating. I was under the impression that the 4DD configuration meant a hard-hitting, brain-shattering bass, but my assumption was wrong. The bass definition on these iems is quite different. It's a thick and rich bass with a lot of boost in the mid-bass region. The bass is not fast, and there is a slow bass decay, indicating a more lingering or sustained bass response. The bass is very, very thick, and it's all over the frequency spectrum, dominating the way the mids and treble sound on these. This is not a hard-hitting bass with full subbass rumbles but a thick, enveloping bass where bass is spread everywhere. The subbass presence is not distinctly felt. It sort of vanishes under the impact of a thick midbass.
Mids:
The bass is all over the mid-frequency range, and there is a lot of bass bleed. This adds to the thickness in the lower mids. The vocals benefit a lot from the thickness and sound quite full—both male and female vocals. There is a fair hint of sweetness in the mids, which adds a lot to the musical timbre and tonality. The upper mids are well-bodied too, but there is a slight hint of shoutiness, which is not quite prominent. Vocal-rich songs are a treat to listen to on these iems.
Treble
The treble on these iems does not carry a lot of energy, and there is a lack of air. The treble misses the crisp nature. It's touching the borderline of a dark treble. However, for me, it is just enough treble. This is a safe zone for treble sensitive people. The tamed treble aligns well with the tuning on these iems. The bass surely kills some fun in the treble region
Technicalities:
For me, Quattro is above average in technicalities. The soundstage is more than average in it's width and depth. Imaging is also above average. The separation of instruments could be a bit better. With a powerful source, this separation becomes better, though. One good thing that is distinctive is the coherency of sound across the frequency spectrum.
Cable Pairing:
The default cable is good enough, as it brings out the true signature. These iems benefit from the good-quality silver cables. There is noticeable openness in the sound on the Effect Audio Code 24 cable. I think this cable has the best pairing of all the cables I tried. A good-quality copper cable adds a hint of warmth, which makes these iems a lot warmer, so that's not an ideal pairing, in my opinion.
Source:
With a warm or underpowered source, the Quattro can sound muffled. It pairs well with a bright source. Also, it is a sucker and needs a lot of power. On my LPGT, I have to turn the volume up to 40–42 to get a good sound out of these. With the Earmen Angel, it sounds better than with the LPGT. Angel has an ESS Sabre ES9038Q2M dac chip and is quite powerful too. With a good, powerful source, the sound is more open too. I also understand that a lot of dongles out there will not be able to bring out the best from these iems, so one should really try to pair them with a wide range of dongles to see which gives them enough juice to shine.
Conclusion:
Quattro is not an IEM built for everyone. I can understand why they can be hit or miss. The timbre and tonality of these iems are something that few can very easily connect to and find very musical. One thing I can surely tell about Quattro is that you have to spend sufficient time (a few days) to decide whether they are aligned with your preferences. On a certain day, with the right set of songs, they can sound so good and timbre-perfect that you will go gaga about them. On a different day, you are tired and not in the zone, and you choose the wrong song, and god, they would just sound awful—not to be confused with whether they are good or bad-sounding.
If you want an iem to throw a lot of precise technicalities and details, this is not the iem for sure. I have seen a lot of people say it is technically very good for an all-DD IEM, but I tend to disagree (just a little). It surely does a lot of good things, but somehow I feel it falls behind many others because of the way it's tuned. There are a lot of details getting eclisped under the bass. I think it's totally fine if it is not technically very sound. I like my iems to be either very technical or to a level where I am not bothered about these technicalities at all. If you love this signature, you may surely enjoy it and call it a winner.
Mini Trifecta??
As soon as I put these on, they reminded me of the Campfire Audio Trifecta. For me, Quattro is a mini-trifecta. I am not sure if Penon took some inspiration from the Trifecta's signature, but these two iems are quite similar in how they sound. And no wonder they both have a very different audience and fan following. Take everything a few levels up—soundstage, detailing, openness—you have the Trifecta with you. Trifecta has a similar bass all over, but it's more open and more spherical, if you know what I mean. Trifecta has troublesome upper mids, which will kind of disturb or annoy you very often if you are sensitive to the frequency. Quattro, however, has just a little hint of a similar thing but does not annoy at all. I remember I liked the Trifecta when I tried them on three different occasions but could never gain the courage to buy them, thinking, What if someday I wake up and find that it's totally disastrous? But I can surely own a Quattro and get some of the Trifecta's feel.
Lastly, I can only say it is really bold of Penon to release something like Quattro. I think this is quite a positive release. This only means they can tune their iems very differently, unlike a few brands who would just stick with a similar tuning and change a thing or two here and there. This presents audiophiles with a unique opportunity to experience a wide range of tuning variations. I am sure Quattro is a very good addition to anyone's collection. If you are the person who does not swear by technicalities on an IEM, Quattro is an easy recommendation. But, it's for sure, not everyone's cup of tea. Some may outright reject them the moment they put it in, but you can't really blame them. I rate these iems 4/5.

A good-quality copper cable adds a hint of warmth, which makes these iems a lot warmer, so that's not an ideal pairing, in my opinion.
Source:
With a warm or underpowered source, the Quattro can sound muffled. It pairs well with a bright source. Also, it is a sucker and needs a lot of power. On my LPGT, I have to turn the volume up to 40–42 to get a good sound out of these. With the Earmen Angel, it sounds better than with the LPGT. Angel has an ESS Sabre ES9038Q2M dac chip and is quite powerful too. With a good, powerful source, the sound is more open too. I also understand that a lot of dongles out there will not be able to bring out the best from these iems, so one should really try to pair them with a wide range of dongles to see which gives them enough juice to shine.
Conclusion:
Quattro is not an IEM built for everyone. I can understand why they can be hit or miss. The timbre and tonality of these iems are something that few can very easily connect to and find very musical. One thing I can surely tell about Quattro is that you have to spend sufficient time (a few days) to decide whether they are aligned with your preferences. On a certain day, with the right set of songs, they can sound so good and timbre-perfect that you will go gaga about them. On a different day, you are tired and not in the zone, and you choose the wrong song, and god, they would just sound awful—not to be confused with whether they are good or bad-sounding.
If you want an iem to throw a lot of precise technicalities and details, this is not the iem for sure. I have seen a lot of people say it is technically very good for an all-DD IEM, but I tend to disagree (just a little). It surely does a lot of good things, but somehow I feel it falls behind many others because of the way it's tuned. There are a lot of details getting eclisped under the bass. I think it's totally fine if it is not technically very sound. I like my iems to be either very technical or to a level where I am not bothered about these technicalities at all. If you love this signature, you may surely enjoy it and call it a winner.
Mini Trifecta??
As soon as I put these on, they reminded me of the Campfire Audio Trifecta. For me, Quattro is a mini-trifecta. I am not sure if Penon took some inspiration from the Trifecta's signature, but these two iems are quite similar in how they sound. And no wonder they both have a very different audience and fan following. Take everything a few levels up—soundstage, detailing, openness—you have the Trifecta with you. Trifecta has a similar bass all over, but it's more open and more spherical, if you know what I mean. Trifecta has troublesome upper mids, which will kind of disturb or annoy you very often if you are sensitive to the frequency. Quattro, however, has just a little hint of a similar thing but does not annoy at all. I remember I liked the Trifecta when I tried them on three different occasions but could never gain the courage to buy them, thinking, What if someday I wake up and find that it's totally disastrous? But I can surely own a Quattro and get some of the Trifecta's feel.
Lastly, I can only say it is really bold of Penon to release something like Quattro. I think this is quite a positive release. This only means they can tune their iems very differently, unlike a few brands who would just stick with a similar tuning and change a thing or two here and there. This presents audiophiles with a unique opportunity to experience a wide range of tuning variations. I am sure Quattro is a very good addition to anyone's collection. If you are the person who does not swear by technicalities on an IEM, Quattro is an easy recommendation. But, it's for sure, not everyone's cup of tea. Some may outright reject them the moment they put it in, but you can't really blame them. I rate these iems 4/5.
Hello everyone, I appreciate you stopping by. Today, I'll be sharing my thoughts on the S15 in-ear monitors (IEMs). While there are already numerous reviews and discussions surrounding these IEMs that provide a fair understanding of their performance, I will try to provide my personal impressions, highlighting what I found appealing and areas where I see scope for improvement.
Letshuoer holds a prominent position in the audiophile community, known for releasing a range of IEMs spanning from budget options to high-end flagships, all well-received by us enthusiasts. Together with 7HZ, Letshuoer has held a special fan following for its production of quality planar IEMs. Letshuoer released the S15 as the successor to the highly regarded S12, integrating newer technologies and accompanying it with a noticeable price hike. In this review, we'll deep dive into what this new generation of IEMs has to offer and assess whether they meet expectations.
I would like to thank @LetShuoer Audio and Ivy for arranging a unit for me. It's important to note that my opinions are entirely unbiased, and I haven't been influenced or instructed to overly praise these IEMs. Every mention in this review is a sincere and honest reflection of my experience.
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. The fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.
Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats, such as price, fit, etc.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Technical Details:
Tech Inside (in simple terms):
According to the official information provided by Letshuoer for these IEMs, they have incorporated several technologies in the development of S15. From my understanding of these implementations, it appears that the primary goal is to provide a comfortable and natural listening experience without causing fatigue.
One notable feature is the implementation of the R-Sonic Passive Filtering Module—a crucial membrane that dynamically adjusts and optimizes the ear canal pressure based on the sound pressure level within the IEMs. This design helps minimize any potential listening fatigue, especially during prolonged use. It sounds like a feedback loop in action.
Additionally, the IEMs feature third-generation planar drivers. While these drivers share a similar size across generations, there have been internal modifications, details of which I'm not able to get my hands on. S15 incorporates a unique design known as a dual acoustic tube structure with a filter crossover scheme. This design ensures the smooth flow of different frequencies to their respective tubes, contributing to a more cohesive and pleasurable listening experience.
Design, build and fit:
When unboxing the iems, the first striking feature you notice is the color scheme and finish of the entire package. The soft blue color, coupled with a matte finish on the case and iems is aesthetically pleasing. So, S15 catches your attention from the first go. The iems are small, lightweight, and quite well built. The combination of the aluminum metal face plate and the soft matte finish on the iem body is quite decent. These iems fit quite nicely and are easy to put on for a very long time without any fatigue.
Additionally, the presence of three vents on the IEMs suggests a design aimed at mitigating pressure buildup, and in my experience, I encountered no issues of pressure buildup during my time with them. I also never encountered any driver flex in these iems, as few have mentioned.
The packaging includes a variety of accessories. The modular cable is well-crafted and offers versatility with interchangeable 2.5, 3.5, and 4.4 adapters. A decent selection of balanced and vocal eartips is also included, although I personally prefer using the Azla SednaFit Light eartips. The wide bore on these eartips, in my opinion, brings out the best sound from the IEMs.
Overall, the unboxing and initial usage experience are highly satisfactory, aligning well with the product's price point. However, the ultimate test lies in the sound quality. We will try to understand the sound profile of these iems in a while.
Sound Analysis:
Right from the get-go, the tuning on these iems is very pleasing. These iems have a warm and balanced signature. The sound is U-shaped, with some bass boost and some emphasis in the upper frequency region, not deviating a lot from a neutral tonality. The timbre is quite good, not shying away from hinting at the typical planar timbre. The sound maintains good coherency. Let's try to understand how different frequencies perform on these iems.
Bass:
Bass is something to talk about on these iems. They have an abundance of bass—punchy and impactful—something that does not seem to be overdone. There is a midbass focus. The subbass, though not very deep and rumbly, shows up when called for, but it's not as prominent. People who like bass on dynamics drivers would not miss a lot with these iems. The quality of the bass is quite commendable for a planar iem. The bass has a natural feel. It does not get bloaty or boomy in the entire low end, maintaining a great balance. The low-end sounds from strings, chello, etc. are very enjoyable.
Compared to bass on something like the EA1000, it is still a few inches behind. The bass on S15 is not as reverbing and natural, but it does not disappoint either.
Mids:
The mids on these iems are clean, thick, and lush, having as much tonal weight as one would need. The vocals are relaxed and hit the right spot. Both male and female vocals shine equally well. Also, thanks to the good technicalities in these iems, the mids get ample space. You can easily distinguish and define the richness and sweetness of sounds coming from instruments such as guitars, violins, etc.
The lower mids have a better body than the upper mids, as the latter has a feel of thinness towards the end of it's spectrum. The upper mids are, however, well controlled, and they do not get sharp or shouty at all. This leads to easy listening most of the time.
I still would not give a full thumbs up to the mids, but then it's tough to point out what exactly is missing. There may be a bit of extra emotional touch, but there are surely very musical and lovely mids there. I also feel the mids could just be a bit forward, but that can be a nitpick. However, on powerful sources, I can see these things do get better, mids have more energy, and they take a front seat. I can most certainly say the mids on these are some of the best ones you can find on the planars.
Treble:
While the bass and mids on these iems are quite well defined, the treble takes a back seat. Treble lacks energy and a sense of airiness but is not far behind either. So, something like cymbal sounds can be felt, but they lose as much shine as one would expect. The presence of air and sparkle in this frequency range is not very pronounced. I am not a treble head, and this treble definition is still fine to me. This is bordering on a dark signature. I enjoy this relaxed signature as it is fatigue-free and fits well with almost every type of music.
When I pair this with the Earmen Angle, which is a neutral to bright source, things certainly get better. A warmer source can make things a bit veiled, and the resolution can take a hit.
Technicalities:
These iems are good at detailing but do not put everything forward. The soundstage on these iems is above average—not the widest, but surely a good width. The depth and height are good enough to give a sense of spaciousness around the head. The imaging and layering are quite good, too. Each instrument gets its due space to shine. However, I do feel resolution could be cleaner, which is somewhat evident on a very busy track. On a less-busy track, things are still quite good.
There is a metallic glare that is present on most of the planars. S15 too has such glare but is less pronounced. With a bit of EQ, things become a lot more natural.
Cable Pairing:
The cable that comes with these iems is quite appropriate. The modularity it offers is truly praiseworthy, catering to quite a lot of sources. I am impressed with the quality and finish of these cables—shiny, sturdy, and visually pleasing. The iems sound as good on this cable as on other cables. I haven't observed a notable improvement in sound quality when using pricier cables; this cable holds its own in delivering a satisfying experience.
Source Pairing:
In terms of driveability, these iems do need a bit of extra juice to shine. Though they are easy to drive, they need powerful sources to show their full potential. They pair well with both the sources I tried, LPGT and Earmen Angel. I do not think it scales too much, but yes, added power does open these iems a lot. Moreover, when paired with a neutral to bright source, such as the Earmen Angel, these iems truly come into their own. The result is an enhanced sense of airiness and openness, elements that contribute significantly to increasing the overall sound quality of these iems. The good thing with these iems is that they do not hiss with Angel, while something like EA1000 and Freya2 do have a background hiss, and they really perform well on Angel, given that it gives it a lot of power.
Comparisons:
With Hidizs MP145 (139 usd):
I am in love with these iems. I am fully biased toward these. They have an extraordinary soundstage, a very vivid out-of-the-head experience.
The bass is on the leaner side. Also, the planar timbre is not quite pronounced on these, but the timbre and tonality on the S15 are definitely better. MP145 is the brighter of the two.
The size of MP145 is massive, so S15 has a much better fit and is lighter of the two.
With Kefine Klanar (90 USD):
In terms of price, these two iems are poles apart, but I do not have any other planar iems to compare the S15 to. Klanar is priced a lot lower than the S15. In terms of fit these iems are quite comfortable. They are light and not quite big.
I love the bass on Klanar, which goes really deep and has enough impact. The bass on both of these iems is quite comparable in terms of weight and impact, though the characters are different. Klanar have thinner mids.
Technically, Klanar does not have the blackest background and cleanest sound, and there is bit of hazy presentation, although this is something one can live with given it's price. Technically, S15 is miles ahead.
Conclusion:
This is the first time I have spent this much time with a planar iem. As far as my understanding of planars goes, they are a hit or miss in terms of timbre. However, with the S15, both timbre and tonality reach great levels. It is one of the good releases from the year 2023. Throughout my time with these iems I never had any complaints, and I enjoyed them as much as I enjoyed my other sets.
But the real question is: Is the price tag justified? I think that's a big question to answer. It's evident that Letshuoer has dedicated significant effort to deliver a comprehensive package with these in-ear monitors. The appealing aesthetics, solid build, generous accessories, and quality cable all underscore the team's commitment to providing a satisfying user experience. While all these elements are justifiable, comparing the S15's price point with other planars and some good non-planar iems reveals a potential disparity. Something like the Hidizs MP145 at 130 USD is a lot more justified when we talk about the price-to-performance ratio. In terms of sound quality, the S15 excels, but the pricing might be perceived as less justified when considering alternatives.
That being said, these iems are one of my favourites from the last year, and I am sure most of the people who have tried them would surely recommend them. They are a lot more than just impressive. Not only are they aesthetically pleasing, but their sound is also beautiful. Who knows, Letshuoer might introduce attractive discounts, making this great experience more accessible to a broader audience. I would rate these iems a 4/5

Hello everyone, and thank you for dropping by. I'm excited to discuss and share my impressions about the EA1000, an in-ear monitor (IEM) that holds a very special place in my heart and ears. Much has been said and shared about the EA1000 already, and it is the flavor of the month for the community. We already have heaps of praise and positive words pouring in from all directions, and love for these IEMs is widespread. I am only going to affirm the same about these iems in my own words.
I've had the pleasure of using these IEMs for the past few weeks. Initially, I was a bit lazy about writing a review, waiting for the right moment and mindset to fully express my thoughts. Interestingly, I wasn't even aware of the existence of the EA1000 until @FiaLm asked me to review it. The Simgot brand name was not something I had encountered frequently until the recent buzz around a couple of IEMs from the brand. I was familiar with the EW200, which, in my opinion, is an outstanding IEM for its price. However, I hadn't come across any other offerings from the brand before. EA1000 is a sweet surprise, for sure.
Once the unit was shipped, I began reading the impressions shared by fellow audiophiles, and the excitement continued to grow. There were good words all around, and I was impressed right from the start. Until a few months ago, I wasn't much into budget IEMs. However, with the OD200 and EA1000, my perspective and focus have shifted. EA1000 has the potential to change someone's views on budget offerings. Are they the best budget IEMs I've heard of? Probably yes, but let's delve into the details, and we'll assess that by the end. I am sure reading this review will help you get a good idea of how these iems sound and what can be expected from them.
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. I think the fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.
Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Technical Details:
Drivers: 10mm dual-magnetic-circuit and dual-cavity structure dynamic
Cable: High-Purity Silver-Plated OFC Litz Structure
Connectors Type: Detachable 0.78mm 2Pin
PRICE: $219.99 USD
Build and fit:
I so much adore the simple yet elegant design of the EA1000. The design on the face plate is a work of art. I am sure everyone has seen the zoomed-in image of those face plates. Doesn't that look adorable? Those metal shells shine brightly and are just exquisite. The shells are small, and the weight seems to be on the heavier side, which is mostly because of the smaller size. Had the size been a bit bigger, the weight would have been better distributed, and they would be lighter. The fit, however, should not be an issue for anyone with small or big ears. For me, it provides a snug fit for my ears without causing any intrusive sensations. It's easy to put these on for longer hours without any fatigue or strain. The nozzle is a bit small and on the wider side. I tried pairing the iems with multiple eartips. Azla Light gives me the best fit, and the shells sit flush inside. I have read a couple of reviews mentioning some fit issues. I think everyone should try these iems with Azla tips; they will find a good fit for sure. Once it fits well and you get a good seal, the bass hits really well. So getting a good fit is of utmost importance for these iems to shine. Also worth mentioning is the non-existence of any pressure buildup whatsoever.
Sound:
Where should I begin while describing the sound quality? These iems are amazingly tuned and highly capable, and I am just blown away by their abilities. The resolution these iems offer is truly exceptional; it's like they have a monster's ability to unravel every fine detail. It's hard to imagine finding such quality sound in this price range and much beyond, and it's even more mind-blowing that a company could achieve this on a budget. They are bright, or, say, treble-focused, but that hot and spicy brightness will not disturb you much. It should not come as a negative aspect of these iems. It does not get to a level to be called overly bright. Honestly, I do not think that's even a thing for these brilliant-sounding iems. The red nozzle is good enough and does bring down the brightness. If you can pair these with a good copper cable and a warmish dap, you are in for a great surprise tour. Let's explore the sound profile in more detail.
Bass:
This is one of the best bass I have heard in a budget- to mid-fi-level iems. I am always on the lookout for good bass, quality over quantity, and these iems possess a very high quality bass. I was in love with the bass since the first time I put them in. It may not be a bass-head level of bass, but I do not think anyone will find them less in quantity. The bass is never underwhelming or overpowering. There is some new tech, and the introduction of a passive radiator makes the bass more fine-tuned and enjoyable. There is a nice feel of reverb and a very lifelike and natural feel to the bass texture. The subbass is quite prominent too. I think these iems have all the goodness of DD bass and add some extra refined bass on top of it. When you listen to some engaging tracks—metal and rock songs—the drums kick with good impact. On less engaging and relaxed tracks, the bass is just right, seamlessly blending with the higher frequencies and allowing you to focus on other aspects of the music. The controlled nature of the bass in these iems truly sets them apart from the crowd.
Mids:
The mids on these iems are just wonderful. They are a bit forward, which aligns with my preference. The tonal weight is quite good, which adds a nice character and body to the mid-range. Thanks to the brilliant resolution on these iems, every tiny detail is brought forward in the most engaging way. The clean and crisp mid-range is the soul of the show for me. This goodness in mids provides clarity and accuracy, allowing vocals and instruments to shine with a natural and lifelike timbre. There is a very nice richness in the way string instruments sound. Overall, there is an emotionally engaging sound that is more romantic than musical. The upper mids have a bit of higher energy but do not get shouty at all. Vocals on these iems must be talked about. There is a sense of warmth and intimacy in the vocals, irrespective of the genres you listen to. Both male and female vocals are full of soul, with no thinness or unwanted heaviness whatsoever. Every bit of raw power and delicate nuance are conveyed properly. Needless to say, this is again an amazing achievement. The mids are always a special sauce for an iem and I am glad to affirm that this sauce is so exceptionally flavorful on the EA1000.
Treble:
I have a bit of sensitivity to treble, but with these iems, I do not find any fatiguing treble. If someone finds the brightness troublesome, they may have to put in some effort to tame the treble, but for me, I am pretty okay with the red nozzle and a decent copper cable. I think my dap, LPGT, which is a bit on the warmer side, also helps a bit. On more reference sources, it may get disturbing for some. But I am sure we can take some pain for our little champion to shine and show it's full potential. Once the treble is sorted and pleasant, it is evidently of very high quality—balanced, detailed, airy, and expansive. I think this treble is likeable for all genres—jazz, rock, metal, pop, anything. There is a very decent level of transparency and clarity in the treble region. The decay of cymbals, the strumming of the guitar, the extension of high-pitched vocals—everything is captured quite beautifully.
Technicalities:
As evident to this point, these sets are highly technical. I am still unsure how these IEMs are so good at resolving details. In terms of resolution, I think they can give a good fight to most of the iems below the 500 USD mark. The soundstage is quite good, though a bit on the intimate side. Still, there is good depth and height. The imaging on these is quite top-notch and accurate. The positioning of instruments can easily be determined; they have such precision. Adding to all this is quite good instrument separation, which does good justice to busy tracks. The layering of instruments unfolds quite nicely.
Cable Pairing:
The cable which comes with these iems are simply nice. This cable is a silver-plated OFC Litz cable. It does lack a 4.4mm termination which many would find bothering. Thankfully most of us have spare cables which come to rescue. But the omission of a 4.4mm termination is really sad because I really like the quality and finish of these cables. They are shiny, sturdy and lovely to look at. The iems sound as good as on this cable as on other cables. Though I do not have any complaints at all with the default resoultion of these iems, they do resolves quite better when given a premium cable. You can imagine how good this thing can be. I have an Effect Audio prototype cable which is sort of premium quality. The bass impact is better and the treble gets bit of taming. There is bit of widening in the soundstage and there is an extra separation in the instruments. The clarity becomes a lot better. All these things make the iems sound quite better. The bass improvement makes it a lot more likeable. That is what some good cables do to the iems. The few areas of improvement which these iems need are nearly sorted by using a good quality cable.

Source Pairing:
These iems benefit the most from a warm source. A neutral or bright source can make the treble a bit spicier, making it difficult for treble-sensitive people. I have a very decent pairing with my LPGT and A&K SP3000. Because of it's massive sound-stage and clarity in it's sound, SP3k takes the EA1000 to another level. I think these iems perform to their full potential on the SP3K. Both of these daps help with better bass delivery. My preference leans towards the SP3k. On the other source, Earmen Angel, due to the better power supplied to the iems, there are again some enhancements in soundstage and dynamics. However, the resolution takes a back seat as the Angel is not so highly resolving dac.
Conclusion:
To be honest, I wanted to spend a significant amount of time with these iems before writing down my thoughts. In a blind test of these IEMs, I am confident that people wouldn't come close to guessing their price. They are so incredibly impressive. Simgot has pushed the boundary to an unprecedented level, stepping up its game. These IEMs set a benchmark and are undoubtedly the best in the $200 USD range. In terms of abilities and technicalities, they can give a good fight to IEMs that are double or triple their price. With some extra effort in cable rolling and perfect source matching, they reach unbelievable levels. If Simgot EA1000 were sold under the brand name Campfire Audio or 64Audio, the iems would have been priced at more than 1000 USD. I am sure no one will disagree with this. I think setting a price of 200 USD is just too absurd. Other brands in market should learn from Simgot about how to deliver a high-end sound within budget.
Not only are they aesthetically pleasing, but their sound is also beautiful. They are so addictive that you'll find yourself reaching for them regularly. It's not your typical single dynamic driver IEM; it offers much more—class-leading technicalities, amazing tuning, and unbelievable resolution. I adore everything about these IEMs to the extent that I no longer feel the urge to spend a lot on IEMs these days. I know some budget iems can be unimaginably good. Paired with the OD200, it stands as my IEM of the year. I am genuinely in love with these IEMs, and they hold a special place in my heart. I hope they bring you the same joy. Highly recommended. 5/5.
I've had the pleasure of using these IEMs for the past few weeks. Initially, I was a bit lazy about writing a review, waiting for the right moment and mindset to fully express my thoughts. Interestingly, I wasn't even aware of the existence of the EA1000 until @FiaLm asked me to review it. The Simgot brand name was not something I had encountered frequently until the recent buzz around a couple of IEMs from the brand. I was familiar with the EW200, which, in my opinion, is an outstanding IEM for its price. However, I hadn't come across any other offerings from the brand before. EA1000 is a sweet surprise, for sure.
Once the unit was shipped, I began reading the impressions shared by fellow audiophiles, and the excitement continued to grow. There were good words all around, and I was impressed right from the start. Until a few months ago, I wasn't much into budget IEMs. However, with the OD200 and EA1000, my perspective and focus have shifted. EA1000 has the potential to change someone's views on budget offerings. Are they the best budget IEMs I've heard of? Probably yes, but let's delve into the details, and we'll assess that by the end. I am sure reading this review will help you get a good idea of how these iems sound and what can be expected from them.
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. I think the fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.
Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Technical Details:
Drivers: 10mm dual-magnetic-circuit and dual-cavity structure dynamic
Cable: High-Purity Silver-Plated OFC Litz Structure
Connectors Type: Detachable 0.78mm 2Pin
PRICE: $219.99 USD
Build and fit:
I so much adore the simple yet elegant design of the EA1000. The design on the face plate is a work of art. I am sure everyone has seen the zoomed-in image of those face plates. Doesn't that look adorable? Those metal shells shine brightly and are just exquisite. The shells are small, and the weight seems to be on the heavier side, which is mostly because of the smaller size. Had the size been a bit bigger, the weight would have been better distributed, and they would be lighter. The fit, however, should not be an issue for anyone with small or big ears. For me, it provides a snug fit for my ears without causing any intrusive sensations. It's easy to put these on for longer hours without any fatigue or strain. The nozzle is a bit small and on the wider side. I tried pairing the iems with multiple eartips. Azla Light gives me the best fit, and the shells sit flush inside. I have read a couple of reviews mentioning some fit issues. I think everyone should try these iems with Azla tips; they will find a good fit for sure. Once it fits well and you get a good seal, the bass hits really well. So getting a good fit is of utmost importance for these iems to shine. Also worth mentioning is the non-existence of any pressure buildup whatsoever.

@activatorfly you will not regret. It’s sound is top class.
activatorfly
My main concern though is their soundstage, which no-one seems to describe...apart from this review that states they have minimal depth. As a musician depth of stage is critical to layer & position instruments in the spherical field...I'm wondering if using a balanced source / cable will make them more holophonic??
nihalsharma
@activatorfly if you give these iem a better source and a good cable, you will have a really good soundstage, layering and enough depth to your liking. The instruments don’t overlap in any way as the resolution and details are already quite good. For busy tracks too, you will find it quite clean and clear in sound. In my case on LPGT and Effect Audio cable there is nice improvement over stock sound. It surely is a keeper.
Tangzu Nezha was released a couple of months ago, in October 2023. The company mentions that this is their first resin-made IEM. Nezha features a customised 7-driver hybrid setup featuring six high-performance balanced armature drivers and an EST driver unit on each side. These IEMs were sent to be reviewed by a friend. I am putting up my honest impressions about Nezha and am in no way influenced by the brand or anyone. 
Specification:
Design and build:
The Tangzu Nezha in-ear monitors (IEMs) have a visually striking design with a vibrant red and black color combination, creating an aesthetically pleasing and attention-grabbing appearance. Additionally, the IEMs exhibit an impressive shine, contributing to their overall appeal. Despite their seemingly big shells, these IEMs are quite lightweight, which ensures comfort during longer usage. I did not feel any fatigue whatsoever. So, quite confidently, I can say that fit should not be an issue for anyone. The package includes a nice set of accessories, notably a high-quality leather case that I really liked. It certainly adds a touch of sophistication to the product. I really like the Tang Sancai eartips that come with these IEMs. All these features collectively make the Tangzu Nezha IEMs a satisfactory product, providing value for their price point.
Accessories:
The included cable with the IEM features oxygen-free copper silver-plated wire and is of very decent quality. It's not prone to tangling. It comes with modular options and offers both 4.4mm and 3.5mm terminations. The cable quite nicely blends with the IEM's aesthetics. Sonically, it very well complements the IEMs sound, and I don't think there is any need to replace it unless you want to go for some cable rolling and find a well-suited pair.
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding.

Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Sound Quality:
Most of my listening was done using the default cable and Azla Light tips, my go-to eartips. The Azla tips fit well on the slightly wider nozzle of these iems. As always, these tips provide a very decent level of isolation, which enhances the listening experience with these IEMs.
Sources Used for Review:
1. Lotoo Paw Gold Touch
2. Earmen Angel
3. iPad Pro
Straight out of the box, the Nezha proves to be good. I find the sound to be a bit on the warmer side. It's ease of driveability and pleasant sound quality remain consistent across different sources. The tuning is particularly likeable. What's even more surprising is the technical performance of these IEMs, which sometimes catch me off guard with their capabilities. The sound is rich in details, creating a sense of spaciousness, and the sound-stage reaches an impressive level. It very easily accommodates a wide range of genres, from metal to acoustics to jazz to everything, making it versatile for various musical preferences. Overall, the Nezha offers an immersive sound experience—something that will keep you hooked from the time you put it in your ears. Let's talk about how these IEMs handle different aspects.
Bass:
The bass in these in-ear monitors (IEMs) maintains the characteristic qualities of balanced-armature (BA) bass. More to that, the implementation of the bass is really different from what I have heard in other BA iems. The Sonion sub-woofers deliver a very pleasing sub-bass, adding a distinct flavor to the lower end. If you are looking for hard-hitting, layered bass, there may be a bit of disappointment. For those who appreciate the nuances and finesse of BA bass, I am sure you will be happy to find the way lower end has been handled on these iems. I am not sure why the bass has been kept so lean.
For example, in Limit to Your Love by James Blake, a song that literally tells how well subbass is handled on an iem, I feel the subbass on Nezha goes quite deep when it is called for but still fails to impress much. In cases where more impact is needed, for example, in metal and rock songs where there is a lot of drumming, there is a lean bass production, which is a bit of a turn-off.
Mids:
The mid-range performance of the Nezha is smooth and enjoyable. Vocals demonstrate a rich quality, and the sound from string instruments carries a good body. However, I perceive a slight thinness in the mid-range at times, particularly noticeable in female vocals, which makes me think that a bit more lushness and thickness could really enhance the overall experience. Per my personal preference, I want the mids and vocals to be a bit forward. I think jazz numbers are ideal for these IEMs, as those strings still sound good on them.
Personally, I haven't detected any peaks or sharpness in the upper mid-range, although for some people, it might approach the borderline for some tracks. In the case of the track Code Cool by Patricia Barber, I don't find any sharpness or sibilance, yet I believe there's room for improvement in rendering the vocals even richer.
On the song Helplessly Hoping by Crosby, Stills, Nash & Young, there is a good separation of the vocals. There is a hint of clarity in the midrange and a sense of warmth, which makes the song sound really good. The sound of male vocals on this track is rich enough to indicate that the male vocals on these iems carry good weight.
Treble:
The upper frequencies are well-extended, capturing the intricacies of instruments and vocals with a very good sense of space and airiness. The treble maintains a balanced presence, contributing to an overall non-fatiguing sound signature. The well-controlled treble on these IEMs contributes to a response that is free from any harsh or piercing elements. This makes the IEMs safely tuned and quite enjoyable, something you'd prefer for longer listening hours.
An example of a good and controlled treble can be heard in the song You've Got to Have Freedom by Pharoah Sanders. The saxophone sound from this track never sounds thin, harsh, or fatiguing. You can really enjoy the raw sound, which can very easily sound coarse on some other IEMs.
Technicalities:
Nezha is a decent pair when it comes to technical prowess. The sound-stage on these IEMs is quite wide, and there is a good sense of spaciousness with good layering. Nezha's open and spacious sound profile handles complex and busy tracks quite well, making it well-suited for genres like metal and rock. The instruments get enough space to breathe. The accuracy in imaging allows for precise positioning of instruments, making it a good choice, particularly with jazz compositions where it does its job really well. Nezha excels quite a lot at detailing too, throwing in those little nuances quite well. However, I need more clarity and a better overall resolution.
Comparison:
I do not generally believe in comparing IEMs as I think every one of them has its own characteristics and a distinct implementation. However, for the sake of positioning an IEM in terms of performance, I would compare these IEMs to my much-loved Simgot EA1000.
Needless to say, in the bass department, the EA1000 is the clear winner of the two. The bass on the EA1000 has a good impactful punch, whereas the Nezha has a very lean and unimpressive bass. This good bass adds quite a bit of fun to the sound on the EA1000 and makes it a lot more enjoyable. In terms of sound-stage, Nezha has a better and noticeably larger sound-stage and the EA1000 is a bit intimate and has just above-average sound-stage, lacking the spaciousness that Nezha has. The mid-range sounds more forward and lusher and has more weight on the EA1000 than on the Nezha. The treble on Nezha is more controlled, whereas on EA1000 it becomes quite hot and spicy at times. EA1000's sound has a cleaner and crisper resolution than on Nezha.
In comparison between the two, I lean more towards the EA1000, and it is a preferable pair for me, which is totally a personal preference based on the above-presented facts.
Areas of improvement for Nezha:
1. I would like the mids to be more forward. Female vocals need a touch of warmth.
2. The bass is not very impressive. The impact is missing.
3. A touch of crispiness and clarity in resolution is certainly needed.
Conclusion:
From the company's perspective, this release really puts Tangzu in the front seat. Nezha, if not an absolute gem, is certainly going to please a lot of listeners. It is still one of the noteworthy releases of the year 2023. The good looks, excellent package, and above-average sound make it a good IEM, and it's nothing short of a winner. I will give them a rating of 4/5: the product is good, and some users may find it more satisfactory, but it does come with a few caveats. The price, in my view, remains justified, but it's important to note that the performance of these IEMs doesn't necessarily exceed expectations for their price range. One can surely grab a unit if they find a really good deal on these IEMs. I will certainly be watching for the next releases from Tangzu.

Sound Quality:
Most of my listening was done using the default cable and Azla Light tips, my go-to eartips. The Azla tips fit well on the slightly wider nozzle of these iems. As always, these tips provide a very decent level of isolation, which enhances the listening experience with these IEMs.

Straight out of the box, the Nezha proves to be good. I find the sound to be a bit on the warmer side. It's ease of driveability and pleasant sound quality remain consistent across different sources. The tuning is particularly likeable. What's even more surprising is the technical performance of these IEMs, which sometimes catch me off guard with their capabilities. The sound is rich in details, creating a sense of spaciousness, and the sound-stage reaches an impressive level. It very easily accommodates a wide range of genres, from metal to acoustics to jazz to everything, making it versatile for various musical preferences. Overall, the Nezha offers an immersive sound experience—something that will keep you hooked from the time you put it in your ears. Let's talk about how these IEMs handle different aspects.
Bass:
The bass in these in-ear monitors (IEMs) maintains the characteristic qualities of balanced-armature (BA) bass. More to that, the implementation of the bass is really different from what I have heard in other BA iems. The Sonion sub-woofers deliver a very pleasing sub-bass, adding a distinct flavor to the lower end. If you are looking for hard-hitting, layered bass, there may be a bit of disappointment. For those who appreciate the nuances and finesse of BA bass, I am sure you will be happy to find the way lower end has been handled on these iems. I am not sure why the bass has been kept so lean.
For example, in Limit to Your Love by James Blake, a song that literally tells how well subbass is handled on an iem, I feel the subbass on Nezha goes quite deep when it is called for but still fails to impress much. In cases where more impact is needed, for example, in metal and rock songs where there is a lot of drumming, there is a lean bass production, which is a bit of a turn-off.
Mids:
The mid-range performance of the Nezha is smooth and enjoyable. Vocals demonstrate a rich quality, and the sound from string instruments carries a good body. However, I perceive a slight thinness in the mid-range at times, particularly noticeable in female vocals, which makes me think that a bit more lushness and thickness could really enhance the overall experience. Per my personal preference, I want the mids and vocals to be a bit forward. I think jazz numbers are ideal for these IEMs, as those strings still sound good on them.
Personally, I haven't detected any peaks or sharpness in the upper mid-range, although for some people, it might approach the borderline for some tracks. In the case of the track Code Cool by Patricia Barber, I don't find any sharpness or sibilance, yet I believe there's room for improvement in rendering the vocals even richer.
On the song Helplessly Hoping by Crosby, Stills, Nash & Young, there is a good separation of the vocals. There is a hint of clarity in the midrange and a sense of warmth, which makes the song sound really good. The sound of male vocals on this track is rich enough to indicate that the male vocals on these iems carry good weight.
Treble:
The upper frequencies are well-extended, capturing the intricacies of instruments and vocals with a very good sense of space and airiness. The treble maintains a balanced presence, contributing to an overall non-fatiguing sound signature. The well-controlled treble on these IEMs contributes to a response that is free from any harsh or piercing elements. This makes the IEMs safely tuned and quite enjoyable, something you'd prefer for longer listening hours.
An example of a good and controlled treble can be heard in the song You've Got to Have Freedom by Pharoah Sanders. The saxophone sound from this track never sounds thin, harsh, or fatiguing. You can really enjoy the raw sound, which can very easily sound coarse on some other IEMs.
Technicalities:
Nezha is a decent pair when it comes to technical prowess. The sound-stage on these IEMs is quite wide, and there is a good sense of spaciousness with good layering. Nezha's open and spacious sound profile handles complex and busy tracks quite well, making it well-suited for genres like metal and rock. The instruments get enough space to breathe. The accuracy in imaging allows for precise positioning of instruments, making it a good choice, particularly with jazz compositions where it does its job really well. Nezha excels quite a lot at detailing too, throwing in those little nuances quite well. However, I need more clarity and a better overall resolution.
Comparison:
I do not generally believe in comparing IEMs as I think every one of them has its own characteristics and a distinct implementation. However, for the sake of positioning an IEM in terms of performance, I would compare these IEMs to my much-loved Simgot EA1000.
Needless to say, in the bass department, the EA1000 is the clear winner of the two. The bass on the EA1000 has a good impactful punch, whereas the Nezha has a very lean and unimpressive bass. This good bass adds quite a bit of fun to the sound on the EA1000 and makes it a lot more enjoyable. In terms of sound-stage, Nezha has a better and noticeably larger sound-stage and the EA1000 is a bit intimate and has just above-average sound-stage, lacking the spaciousness that Nezha has. The mid-range sounds more forward and lusher and has more weight on the EA1000 than on the Nezha. The treble on Nezha is more controlled, whereas on EA1000 it becomes quite hot and spicy at times. EA1000's sound has a cleaner and crisper resolution than on Nezha.
In comparison between the two, I lean more towards the EA1000, and it is a preferable pair for me, which is totally a personal preference based on the above-presented facts.
Areas of improvement for Nezha:
1. I would like the mids to be more forward. Female vocals need a touch of warmth.
2. The bass is not very impressive. The impact is missing.
3. A touch of crispiness and clarity in resolution is certainly needed.
Conclusion:
From the company's perspective, this release really puts Tangzu in the front seat. Nezha, if not an absolute gem, is certainly going to please a lot of listeners. It is still one of the noteworthy releases of the year 2023. The good looks, excellent package, and above-average sound make it a good IEM, and it's nothing short of a winner. I will give them a rating of 4/5: the product is good, and some users may find it more satisfactory, but it does come with a few caveats. The price, in my view, remains justified, but it's important to note that the performance of these IEMs doesn't necessarily exceed expectations for their price range. One can surely grab a unit if they find a really good deal on these IEMs. I will certainly be watching for the next releases from Tangzu.
Where do I begin while reviewing this magical little thing? At the time of my search for a good amp, the options were limited, with Centrance facing some availability issues; the 475 received sparse reviews by then and it seemed too powerful for the IEMs. Aroma A100tb was the one that was easily available, and the price tag was quite good. There were all good things said about it everywhere, and no negative thing was said about it. Amidst all this, I came across the review of A100TB by @Tokpakorlo . The review was so precise and fluid that it convinced me to buy the Aroma amp stack. I bought the Aroma stack in August from @MusicTeck. Andrew was kind and patient enough with my queries, and it was overall a good buying experience as always. Since this unit was personally carried by a friend from the US, I had to wait for a long time, 3–4 weeks. Finally, the day arrived when the Aroma stack was in my hands. Throughout the waiting period, added to by discussions with various individuals, my expectations for the Aroma stack had reached a great height.
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. I think the fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.
Design and build:
A100TB is a small amp by design and will fit well even in your palm. You can charge the amp with a 5V/2A adapter using a USB-C cable, and it takes approximately 4 hours for a full charge. While I haven't precisely timed its battery life, it typically lasts for a commendable 7-8 hours. There is a battery indicator that tells you the amount of battery left on the device, which is really helpful at times. The battery on the amp is removable and can come off quite easily, which is another good thing about it in case the battery dies after long usage. The video below shows how to remove the battery easily. One of the major features of the amp is that you can change the opamps on it. From my discussions with fellow headfiers, I gathered that the Burson V5Di changes the sound and makes it a lot better than the default. I just cannot imagine what an improvement that could be for something that sounds so wonderful. I was also suggested by a friend to get the LM6172, which also changes the sound significantly. Regrettably, I haven't experimented with these enhancements yet, so I am not aware of the extent of change they might bring.
Sound impressions:
For the first time, when I plugged it into my LPGT, the sound through the amp was just unbelievable. I could not believe what I was hearing. It's magical to listen to the difference this amp can bring. And this was just the amp, without the power supply. I had previously used a few amps (Astell & Kern PA10, Earmen Angel, etc.), but none of them had hooked me this much from the start. I could appreciate the PA10 quite a lot when I first tried it, as it does darken the background quite a bit and improve some bit of dynamics. Similarly to the Earmen Angel, it also does quite a good job as it is quite powerful. But in comparison to these two, the Aroma amp is something else. It changes the whole listening experience. The level of dynamics it adds, the richness in sound that the iems produce, the enhancement in the overall perception of soundstage, the increase in musicality—everything is leveled up. It seems that the IEM that you are listening to is a different one.
I always used to believe and hear that amps were capable of creating such magic, but witnessing this thing was a whole new experience. There is quite a lot of change that comes with the power and the amp circuitry, which refines the audio signals. The A100tb has a transparent reproduction without changing the signature. To me, I cannot call it a reference sound or a neutral sound. It does add some warmth to the sound, but that added warmth is not much, so you won't feel any coloration. It's all about the dynamics that are added to the sound. It becomes quite intense, massive, but never too overpowering and overwhelming, and more engaging. The bass becomes quite tight, and the impact is quite noticeably different. The macro nuances and details are more pronounced, and these smaller details, which were somewhat faint earlier, have become quite noticeable. The sound is richer and fuller, and it gains a lot of weight without an actual change in signature.
Adding this to the LPGT gives some extra sense of spaciousness and a better head-stage. The bass and dynamics on it become quite good, though LPGT has a good bass by itself. The amp section on the LPGT is quite decent. Astell&Kern SP3K sees quite a decent improvement in sound, as the amp section on it is not as powerful as on the LPGT. I am not sure of the difference in specs, though. SP3K, by default, has an amazing soundstage and clarity in its sound. Adding A100TB makes the mids sound so sweet, full, and rich. The added weight to the overall sound does wonders. Talking about the IEMs, the amp gives them wings to fly. There is no doubt that IEMs scale quite a lot with good sources. I have tried many iems with the A100TB and seen them go to great levels: Fourte, Jewel, Kublai Khan and Ragnar, to name a few. Anyone who has tried Ragnar knows well that it needs quite a good source with enough power to show it's true colors. When I tried Ragnar on Lotoo Paw Gold Touch, Ragnar on PWAudio First Times, and Aroma A100tb, it sounded so incredibly amazing. I am very sure that for Ragnar, there are only a very few chains that can produce as great a sound as this. Aroma amps gave a new life to Ragnar when I demoed them. On a weaker source, Ragnar would just not sound right, but with juices flowing from A100tb, things were quite different. This same story happens with all the IEMs you try with this amp. The amp opens up the sound so much that everything sounds gigantic, like the IEMs are on steroids. Somehow, this level of craziness is not achieved when you use any other amp, such as the PA10 or Angel, which means there must be something different in the way this amp is designed. There is not just power that makes things better, but the clean, dark, and silent background, which makes it quite distinguished. There is never a hiss despise of so much power the amp delivers; that's one more thing to like about it.
Though I never use headphones, I've noticed that the power output on the Aroma falls somewhat short for driving more power-hungry headphones effectively. In my opinion, it can drive headphones, which are less power-hungry. I remember it could not drive one of my friend's HD660s quite optimally. In contrast, the other amps, Earmen Angel and iFi Signature, could play the headphones quite easily. I cannot say for sure if it is good enough for headphones.
Adding the PS100 Pro:
After enjoying a satisfying dinner and feeling comfortably full, indulging in a small dessert is an irresistible temptation—one that you never turn down. In this similar analogy, the PS100 plays the role of that delightful dessert, providing the final touch of satisfaction to an already amazing A100TB experience. On top of an already amazing sound, it adds the last bit of dark and silent background. In the first few listens, the change won't be that noticeable, but when you are accustomed to the sound of A100tb, you will start noticing the difference. I did not use the PS100 for quite some time after initial usage, and then later, when I put it to use, there was certainly a cleaner and more silent sound I could hear. The battery on the PS100 lasts for about 7-8 hours. I keep it attached to the amp most of the time. It's like having an extra power backup for the amp, reserving the power on the main amp, and using the power supply. The socket that connects the PS to the amp is quite weird in the sense that it does not connect easily, which is quite a struggle there. I remember that once it took me 20 minutes to connect the plug, so I always keep it plugged. The best part about the PS100 is that it's not costly, so it can be easily bought along with the amp. You won't miss a lot if you do not get it. Also, a word of caution: do not switch on the amp when the PS is plugged in. It may add an extra thrust of power, which may damage the IEMs.
Conclusion:
I took the leap in acquiring this stack—a blind purchase, devoid of firsthand experience. However, upon its arrival, it left me utterly speechless. I enthusiastically informed a lot of people about its exceptional sound quality. Eventually, it became a centrepiece for me, something I would show off to someone who visited my place for an audio meetup. Everyone from my audiophile community who has tried the A100TB echoes the same sentiments, and everyone is impressed by its abilities. It now has a different fan following in our group. For me, it was a blind buy, but that led six different people to join the gang, which in a way gives me a lot of satisfaction. It's such an exquisite little device that leaves everyone happy.
I am more impressed with Aroma as a brand. These people are doing some serious R&D on the products they are developing, creating unique and brilliant products one after another. Aroma Jewel and the recent Fei Wan are compelling evidence of their exceptional craftsmanship, and so is this amazing amp stack. To sum it up, the A100tb is one of the best portable amps on the market. With it's amazing power and driving ability, it turns the iems into different beasts. Imagine the finely tuned and strung strings on the guitar that produce the best sound note while still having enough strength to withhold vigorous strumming. In the same way, sound production through the amp is quite strong and optimal, yet controlled. The sweet and reasonable price tag on it makes it even more likeable. Along with the PS100 Pro, the stack is undeniably one hell of an experience. If you want to experience the joy of an immersive and unforgettable auditory experience, just go for it. A perfect 5/5 product.

Intro:
The Oriveti OD200 was a real surprise for me. I have loved it thoroughly, and it is my daily driver. It’s one of those beautiful IEMs that you would like to keep forever. After it, I was very intrigued by the 700. I even asked the folks at Oriveti to send me a sample unit that I could review, but they declined, saying they had run out of samples. Nevertheless, I have a couple of friends here in India who have the OH700VB. I borrowed my unit from @Ace Bee. This review is going to be very honest and unbiased.
The OH700VB retails for $699 and is available for purchase on their website.

Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Design and build quality:
The IEM shells are made of resin. They are not too big; they are very lightweight, and they fit really well. Fit should be an issue for anyone. One can put them in their ears for a very long time without feeling an itch to remove them. Most of the accessories are the same as with the OD200. I really hoped that with OH700VB, because of its price, I would ask for some better treatment. There is nothing much to complain about.
The nozzle on the IEMs is on the wider side. Azla Light tips (L) are the ones that I use and find to be the best fit. Azla Light is my saviour for so many IEMs; I cannot thank them enough. These eartips provide a very decent level of isolation, which enhances the listening experience on the IEMs.
Sound Quality:
Right out of the box, the 700 is quite likeable. It’s easy to drive, and it sounds good, irrespective of source. It has very fun tuning, and it is a bass lover's delight. It works with almost all genres and can easily cater to various musical preferences. The switch on the face plate is the real deal. It will take you on a very different joy ride. There are a lot of details in the sound. There is a sense of spaciousness. Overall, it has a very immersive sound; it has everything, which does not let you put off the iems. Let’s talk more about how it handles different frequencies.
Sources:
Bass:
Bass, bass, more bass. As mentioned, these iems are a bass lover's delight. Both the quantity and quality are just too good. The bass has good layering and texture. With the best switches on, they become real monsters, still very controlled and disciplined. The bass becomes so vast and massive with so much punch and that subbass. The subbass gets a lot of body and prominence when the switches are on, and that’s the most fun part about these IEMs. Going by the FR graph, I was really surprised to see how much of a difference 3 dB can make. There is a great extension in the bass, which reaches deep into the lower frequencies. The bass with such good quantity is surprising well balanced. It never bleeds into or touches other frequencies, and that is where I think Oriveti has done a wonderful job.
Mids:
The mids are well-balanced, clean, clear, sweet, and very enjoyable. Despite the fact that these IEMs have a heavy bass, the mids are never shadowed. They are as forward-thinking as one would like them to be. Female vocals feel extremely sweet and soft, something that is very lifelike. The male vocals are also equally good. There is a touch of warmth, providing richness and fullness to vocals and instruments without compromising clarity. The emotional essence of midrange is well conveyed. The upper mids can be a bit sharp at times with some sources. All in all, I think ORIVETI deserves praise for how beautifully they tune their mids; for reference, the mids in the OD200 are also too good. With such good bass and such good mids on the OH700VB, the IEM is already a winner.
Treble:
For me, the treble is very natural and airy, with good extension. There is no sibilance or any sort of harshness. Even with one of my brighter sources, I did not find the treble to be too hot to handle. This gives me the feeling that this is very safe. While it may not be perfect for treble-heads, for me, it is just enough to enjoy. It captures the shimmers of cymbals on songs such as The Chain by Fleetwood Mac quite nicely.
Soundstage:
There is a good sense of height and a lot of depth in the soundstage, which makes it very enjoyable. There is a good sense of spaciousness and a holographic sound experience. The instruments do not overlap with each other, and there is no congestion at all. With a good source such as Astell&Kern SP3000, the sound stage becomes very wide, and there is a lot of improvement in dynamics. Listening to something like Sinnerman by Nina Simone is such a delight.
The resolution of these IEMs is something that can surprise people. They are really good at retrieving intricate details in the music, but let’s not expect those details to be as good as TOTL IEMs. The OH700VB provides a consistently smooth listening experience while still preserving ample detail and offering a notably expansive soundstage. In a nutshell, I find 700 to be a technically efficient IEM.
Cable:
The cable is the same as the one that comes with the OD200, so that's the only major gripe I have with these IEMs. Even with this cable, I think the IEMs work quite well. For the sake of cable rolling, I tried it with a good-quality copper cable, and there was a good improvement in the tonal weight. With this cable, there was some improvement in the upper mids too, and there was more weight to the mids, which I really liked.
Conclusion:
Oriveti deserves another round of applause for the OH700VB. It’s really amazing to see them deliver one hit after another. They really know how to tune their IEMs. The OH700VB iems are one of the easiest recommendations that I can give to fellow audiophiles. These IEMs are full of fun and excitement. With an impressive combination of deep, impactful bass and clear, detailed mids, this IEM offers a rich and balanced sonic experience. It's quite surprising how its tuning is totally different and unrelatable from that on the OD200. I also think that the company has priced the OH700VB really well. It can give a really good fight to the other good iems in the price range, such as SoundRhyme DTE900 and SR8. No matter what your preference is - technicalities, or deep bass, or whatever - these IEMs will deliver. It certainly cannot disappoint anyone.
The Oriveti OD200 was a real surprise for me. I have loved it thoroughly, and it is my daily driver. It’s one of those beautiful IEMs that you would like to keep forever. After it, I was very intrigued by the 700. I even asked the folks at Oriveti to send me a sample unit that I could review, but they declined, saying they had run out of samples. Nevertheless, I have a couple of friends here in India who have the OH700VB. I borrowed my unit from @Ace Bee. This review is going to be very honest and unbiased.
The OH700VB retails for $699 and is available for purchase on their website.
Rating Criteria:
I want to lay out my rating criteria before we start off. For me, the primary criterion for evaluating audio gear is its intrinsic value rather than its price tag. A higher price doesn't always correlate with superior quality, and similarly, a low-priced product can give enough listening pleasure for it to be called outstanding. I consider the build, features, and, most importantly, the impact on the listening experience. I think the fundamental purpose of audio gear is to enhance the listening experience. So for me, this degree of enhancement in the listening experience is a key determinant in rating a product.
Rating below 4: I really won't be posting reviews of such items unless someone has asked for them.
Rating of 4: The product is good, and some users may find it more satisfactory, but it does come with a few caveats.
Rating of 4.5: The product is excellent and comes with an easy recommendation, reflecting its high quality and overall positive attributes.
Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Design and build quality:
The IEM shells are made of resin. They are not too big; they are very lightweight, and they fit really well. Fit should be an issue for anyone. One can put them in their ears for a very long time without feeling an itch to remove them. Most of the accessories are the same as with the OD200. I really hoped that with OH700VB, because of its price, I would ask for some better treatment. There is nothing much to complain about.
The nozzle on the IEMs is on the wider side. Azla Light tips (L) are the ones that I use and find to be the best fit. Azla Light is my saviour for so many IEMs; I cannot thank them enough. These eartips provide a very decent level of isolation, which enhances the listening experience on the IEMs.
Sound Quality:
Right out of the box, the 700 is quite likeable. It’s easy to drive, and it sounds good, irrespective of source. It has very fun tuning, and it is a bass lover's delight. It works with almost all genres and can easily cater to various musical preferences. The switch on the face plate is the real deal. It will take you on a very different joy ride. There are a lot of details in the sound. There is a sense of spaciousness. Overall, it has a very immersive sound; it has everything, which does not let you put off the iems. Let’s talk more about how it handles different frequencies.

Bass:
Bass, bass, more bass. As mentioned, these iems are a bass lover's delight. Both the quantity and quality are just too good. The bass has good layering and texture. With the best switches on, they become real monsters, still very controlled and disciplined. The bass becomes so vast and massive with so much punch and that subbass. The subbass gets a lot of body and prominence when the switches are on, and that’s the most fun part about these IEMs. Going by the FR graph, I was really surprised to see how much of a difference 3 dB can make. There is a great extension in the bass, which reaches deep into the lower frequencies. The bass with such good quantity is surprising well balanced. It never bleeds into or touches other frequencies, and that is where I think Oriveti has done a wonderful job.
Mids:
The mids are well-balanced, clean, clear, sweet, and very enjoyable. Despite the fact that these IEMs have a heavy bass, the mids are never shadowed. They are as forward-thinking as one would like them to be. Female vocals feel extremely sweet and soft, something that is very lifelike. The male vocals are also equally good. There is a touch of warmth, providing richness and fullness to vocals and instruments without compromising clarity. The emotional essence of midrange is well conveyed. The upper mids can be a bit sharp at times with some sources. All in all, I think ORIVETI deserves praise for how beautifully they tune their mids; for reference, the mids in the OD200 are also too good. With such good bass and such good mids on the OH700VB, the IEM is already a winner.
Treble:
For me, the treble is very natural and airy, with good extension. There is no sibilance or any sort of harshness. Even with one of my brighter sources, I did not find the treble to be too hot to handle. This gives me the feeling that this is very safe. While it may not be perfect for treble-heads, for me, it is just enough to enjoy. It captures the shimmers of cymbals on songs such as The Chain by Fleetwood Mac quite nicely.
Soundstage:
There is a good sense of height and a lot of depth in the soundstage, which makes it very enjoyable. There is a good sense of spaciousness and a holographic sound experience. The instruments do not overlap with each other, and there is no congestion at all. With a good source such as Astell&Kern SP3000, the sound stage becomes very wide, and there is a lot of improvement in dynamics. Listening to something like Sinnerman by Nina Simone is such a delight.
The resolution of these IEMs is something that can surprise people. They are really good at retrieving intricate details in the music, but let’s not expect those details to be as good as TOTL IEMs. The OH700VB provides a consistently smooth listening experience while still preserving ample detail and offering a notably expansive soundstage. In a nutshell, I find 700 to be a technically efficient IEM.
Cable:
The cable is the same as the one that comes with the OD200, so that's the only major gripe I have with these IEMs. Even with this cable, I think the IEMs work quite well. For the sake of cable rolling, I tried it with a good-quality copper cable, and there was a good improvement in the tonal weight. With this cable, there was some improvement in the upper mids too, and there was more weight to the mids, which I really liked.
Conclusion:
Oriveti deserves another round of applause for the OH700VB. It’s really amazing to see them deliver one hit after another. They really know how to tune their IEMs. The OH700VB iems are one of the easiest recommendations that I can give to fellow audiophiles. These IEMs are full of fun and excitement.

@alexandros a yea bro, they really are midfi champion and one of the best releases in the segment in past few months. You will love the sound on it.
A few weeks ago, I invited @Ace Bee for auditioning few iems I had with me. I was unaware of the existence of OD200 until that time. I also had not stumbled upon any posts about these iems. He brought a pair of OD200s with him, and out of curiosity, I tried them as they looked really cool. What I heard in the first listen was a quite satisfying sound - something unexpected of an iem priced at 200$. The very next day, I bought a pair for myself from my local dealer. These impressions below are unbiased, honest, and reflective of what I think about these iems.
One word that truly defines the OD200 is rare. I will start my review by thanking the makers of OD200. I had never expected an iem, at this price point, to be of such high quality tuning. My time with the OD200 has been really really good. These iems are nothing sort of gems. Since the first listen to the present day, I have listened to them daily and have enjoyed them a lot. They get more time than my other iems, some of which are really expensive.

Rating of 5: This product can be deemed groundbreaking, a trendsetter, and an eye-opener and deserves a spot on everyone's list due to its exceptional features and outstanding performance.
Let's deep dive into the various aspects.
Design and build quality:
- OD200 has a very nice, solid build, which feels very premium. The green colour on it is very nicely finished. The packaging of the iems is also quite good. The case, the eartip selection, and the cable are of very decent quality. The unboxing experience is quite satisfying.
Comfort and Fit:
- The iems are very comfortable to wear for long hours. There is no discomfort at all. I think it has to do with the smaller shape of the iems. One thing that may bother a lot of people is the smaller nozzle. It may be tricky to find a good fit for a few people. Tip selection is really important here. I tried a lot of different tips - SpinFit W1, Divinus Velvet, Tanzu colorful tips, Final E type tips, etc. - and eventually settled on Azla light tips. I think there are no better tips to go with the OD200. The wide bore on the tips settles very nicely in the ear and gives a very good fit and nice isolation - something that enhances the sound coming through the iems.
Sound Quality:
- Right out of the box, the OD200 is a surprise trip. It is quite easy to drive and has very mature and well-balanced tuning. In my time with the OD200 so far, I have paired it with the A&K SP3000, LPGT, and Earmen Angel. These iems sound a lot better with neutral sources. With good, powerful sources, they sound even better. The detailing and resolution, the sense of spaciousness, get better with good sources.
The tuning on the OD200 is really exceptional, as if it were tuned using some rulebook. It is not a typical ChiFi tuning, but rather a very mature one. One of the safest tunings that I have found on a budget iem. There is an excellent amount of bass, the mids are sweet, and the treble is as airy as you would like them to be. The tonal weight is pretty decent. All the frequencies have a very coherent sound, and each frequency range gets enough space. The sound stage and imaging are quite good. There is a good sense of spaciousness, and you won’t feel any congestion in the instruments that are being played. It is very obvious that at this price range, you won’t/shouldn't be expecting and imaging it to be as good as the Z1R, but yes, it does, it's works, and you will love it.
Bass:
There is more than enough bass on these iems. If you are a basshead, I think you will instantly fall in love with these iems. With the silver module, the bass is more pronounced and can satisfy someone's bass hunger. If you want the bass to be a bit shy, the black module can be of use. The bass on the silver module has enough quantity to it and has a good quality as well. The bass is punchy, well controlled, and not overwhelming at all. There is a noticeable subbass presence too. The bass, even if it has decent quantity, never bleeds into other frequencies.
Mids:
The mids on the OD200 are very pleasant to the ears. It's sweet, well-bodied, and does not get harsh at all. The strings, keyboard, vocals, etc. all sound quite rich and emotional. Achieving such good mids on a budget iem is a feat in itself. Mids are quite forward; there is nothing recessed. A special mention should be given to how crazy good the vocals on these iems sound. The vocals on OD200 are unbelievably good, and they get better day by day. Vocals sound so real that it feels unreal sometimes. For reference, I tried Z1R few days ago, and the vocals on it are dry for my preference, especially the male vocals. I am enjoying vocals on OD200 a lot more than on many other good/kilobuck iems.
Treble:
I am not a treble-head, so for me, the treble on the OD200 is just enough. With that said, I do not miss any treble details on the iems. There is enough air, no harshness, no shouts. I find it well extended and well controlled as far as the upper frequencies are concerned. All in all, I do not find anything lacking in this region of frequency. Also, with a brighter source, the treble can get quite hot, so I suggest going with a non-bright source.
Cable Quality:
- The default cable that came with the iems is of decent quality. Though it is soft and tangles a bit, it eventually does its work. Many times, I listen for long hours on the default cable only. The cable is modular, and it has three different adapters - 4.4mm, 3.5mm, 2.5mm to fit multiple needs. For the sake of cable rolling, I tried it with a good-quality copper cable, and there was a good improvement in the tonal weight. For the price of these iems, the cable is just right.
Conclusion:
OD200 is an exceptional iem, as simple as that. It is really hard to explain and put in words how satisfying these iems sound. If you are a longtime audiophile and have given enough time to the hobby, I am sure you will love what these iems have to offer. I do not think there is any improvement needed on these iems, nothing needs changing. All the frequencies are equally enjoyable. I do not think there is anything at all to complain about about these iems. I also do not think these iems should be compared to other ones. At this price, if some iems perform so well, you tend to forget what it costs and just appreciate the satisfaction it gives. It is a no-brainer to get a pair of the OD200. If your primary goal is to truly enjoy your music library, the OD200 stands out as a highly satisfying choice, comparable to other highly esteemed IEMs on the market.
Setting a trend:
It's a great time to associate ourselves with the audiophile hobby. Thanks to the makers, both producing high-end iems and budget iems. There is certainly a lot of innovation happening around, as we can see. The market is hot and spicy but we cannot really ignore the price tag associated with the iems in the market. I have bought and sold and bought expensive iems, but it's such budget iems as the OD200 that perform and satisfy way above their price range, which really makes me go gaga. From an expensive iem, your expectations are set; if something turns bad, it leaves you really disappointed. For the budget/inexpensive iems, it's different. If something makes you happy at this price point, you enjoy spending your time with iems as much as you do with your expensive iems.
For me, the OD200 are trendsetters. In today's crowded market, especially in the low budgets range, just like the iems - Night Oblivion Butastur and SoundRhyme SR8, OD200 is nothing less than a gem. Budget in-ear monitors (IEMs), exemplified by gems like the OD200, are causing (and should be) quite a stir in the audiophile community. I want to give a shout-out to the makers who work hard to innovate and create fantastic iems without a hefty price tag. This kind of great value not only makes the community members happy but also should be treated as a lesson by the other manufacturers. These affordable marvels are challenging and shattering the long-held myth that exceptional sound quality is exclusively reserved for high-priced IEMs. It shows that top-notch quality doesn't have to be super expensive. It's like a friendly nudge to the whole industry, saying, "Hey, let's make awesome audio accessible to everyone!"
So, big thanks to those who make great stuff without breaking the bank – Orivetti, you're setting a cool example for others to follow! I am a big, big fan now. Please keep on delivering such good-quality iems.

Hit the nail on the head in this review. Having owned and moved on from a bunch of the usual recommendations in the sub-$300 single DD market, I can say that the OD200 is my choice for best in that category (and possibly more) by a significant margin. I don't think you really take a significant step beyond these with single DD IEMs until you hit more premium options like the Zen Pro or Twilights. I don't think I'm alone in saying that the OD200s are the affordable single DD set I've been waiting for. 
Introduction:
We audiophiles are always on the lookout for the next hidden gem, and one such discovery is Night Oblivion Butastur. It's an all-BA driver IEM with 10 drivers on each side. It is available on PenonAudio.
Link: https://penonaudio.com/Night-Oblivion-Butastur
I got to demo it through a friend. There were a lot of words and praises about it on the Head-Fi thread. When a product surpasses your expectations, it's a moment of delight for any of us in the hobby. I must say this is a brilliant IEM, and I did not expect it to be so good. Well, for the price tag, they are a steal. To assess the capabilities of the Butastur IEM, I tried it on a variety of sources, including the Lotoo Paw Gold Touch, Aroma A100TB, Earmen Angel, and Shanling M7. Please be mindful of the fact that Butastur needs good (resolving and powerful) sources to shine, as it may sound thinner and unexciting on not-so-good-and-resolving sources.
Impressions:
Comfortable Fit:
One of the first things that struck me was the comfort of the Butastur IEMs. Their small and lightweight shells make for a comfortable listening experience, even during extended sessions. There are too many multi-drivers these days that are too big to fit in ears sometimes. It's good to see the maker has packed so many drivers in a small shell.
Cable and Tips:
The included cable met our expectations, and when paired with SpinFit W1 tips, it complemented the IEMs perfectly. The Azla Sedna Light tips really fit very well on it, better than Spinfit w1 and H570 eartips(which the @AmericanSpirit_JP has suggested). H570 is a bit wide for my ear canal. Just for the sake of it, I changed the cable on it to the cable that comes with Kublai Khan, which is just decent, nothing great. I am sure there is a slightly better dynamic—not much, but surely it’s there. I don’t have a better cable than this, so I can’t say much.
Tuning Switches:
One thing that stands out and shouts in your head when you put these IEMs in your ears is their great tuning. Tuning can really put you off or get you excited. There are so many good IEMs that fail to impress eventually due to their poor (slightly off) tuning. Butastur is amazingly tuned. On top of that, it comes with multiple tuning options, and I find the 1-0 tuning (bass up and treble down) to be my preferred choice. I don't feel the need to adjust the default treble; it sounded just right.
Impressive Bass:
For an all-balanced armature (BA) IEMs, the bass performance is just outstanding. It's well controlled, clean, fast, snappy, and surprisingly, I don't miss the dynamic driver (DD) bass on these IEMs. DD bas has definitely an edge if done perfectly right, but Butastur's bass is too good for all BA IEMs. With the right tips and proper fit, the bass feels really tight, and it slams really well. No complaints at all.
Sweet Mids and Decent Staging:
The midrange on the Butastur IEMs is sweet and well-balanced. Vocals are such a charm on these IEMs—emotional and engaging. The staging and imaging are both very decent, and what's most notable is the seamless cohesion among different frequencies. There's no sense of frequencies stepping on each other; they each have their space to shine. Contrary to concerns about thin sound, the Butastur IEMs, especially when paired with high-end setups like the Lotoo Paw Gold Touch and Aroma amp, produce notes with enough weight and body. This results in a rich and immersive audio experience.
Conclusion:
Tuning is the real secret sauce.
In my time with the Butastur, it became clear that this product is not just another IEM packed with a high number of drivers. It's a testament to the importance of good tuning. If an IEM is well tuned, it can sound really amazing. Butastur elevates your audio experience by providing superb resolution and preserving the authentic timbre of the music. These IEMS have been designed to impress, to break the myth that only kilobuck and flaships can sound good (still not a kilobuck killer). Butastur truly shines when paired with high-quality sources, such as the Lotoo Paw Gold Touch and Aroma amp. They deliver performance that exceeds their price range, making them a Mid-Fi King in their own right. It has pretty much everything you look for in a great IEM. It If you're in search of IEMs that offer exceptional value for money, the Butastur IEMs are undoubtedly worth considering. Quite an achievement for an IEM priced at 500–600 USD.
Is it a Kilobuck Killer?
I would say no. Let's not put such a label on these categories of IEMs. They have been built for users to enjoy and make listening fun, because the tuning says so. They are likeable from the first time you put them on. But they certainly lack the technicalities and microdynamics that some kilobuck iems have. Butastur may be more fun-sounding than some of the IEMs priced 2-3 times higher, but when compared to the good ones, there may be a few things missing. But should you care when the price is so low? I think I go by this attitude. For some fun sessions, I would certainly spend some time with the Butastur and give these iems the love they deserve.
We audiophiles are always on the lookout for the next hidden gem, and one such discovery is Night Oblivion Butastur. It's an all-BA driver IEM with 10 drivers on each side. It is available on PenonAudio.

I got to demo it through a friend. There were a lot of words and praises about it on the Head-Fi thread. When a product surpasses your expectations, it's a moment of delight for any of us in the hobby. I must say this is a brilliant IEM, and I did not expect it to be so good. Well, for the price tag, they are a steal. To assess the capabilities of the Butastur IEM, I tried it on a variety of sources, including the Lotoo Paw Gold Touch, Aroma A100TB, Earmen Angel, and Shanling M7. Please be mindful of the fact that Butastur needs good (resolving and powerful) sources to shine, as it may sound thinner and unexciting on not-so-good-and-resolving sources.
Impressions:
Comfortable Fit:
One of the first things that struck me was the comfort of the Butastur IEMs. Their small and lightweight shells make for a comfortable listening experience, even during extended sessions. There are too many multi-drivers these days that are too big to fit in ears sometimes. It's good to see the maker has packed so many drivers in a small shell.
Cable and Tips:
The included cable met our expectations, and when paired with SpinFit W1 tips, it complemented the IEMs perfectly. The Azla Sedna Light tips really fit very well on it, better than Spinfit w1 and H570 eartips(which the @AmericanSpirit_JP has suggested). H570 is a bit wide for my ear canal. Just for the sake of it, I changed the cable on it to the cable that comes with Kublai Khan, which is just decent, nothing great. I am sure there is a slightly better dynamic—not much, but surely it’s there. I don’t have a better cable than this, so I can’t say much.
Tuning Switches:
One thing that stands out and shouts in your head when you put these IEMs in your ears is their great tuning. Tuning can really put you off or get you excited. There are so many good IEMs that fail to impress eventually due to their poor (slightly off) tuning. Butastur is amazingly tuned. On top of that, it comes with multiple tuning options, and I find the 1-0 tuning (bass up and treble down) to be my preferred choice. I don't feel the need to adjust the default treble; it sounded just right.
Impressive Bass:
For an all-balanced armature (BA) IEMs, the bass performance is just outstanding. It's well controlled, clean, fast, snappy, and surprisingly, I don't miss the dynamic driver (DD) bass on these IEMs. DD bas has definitely an edge if done perfectly right, but Butastur's bass is too good for all BA IEMs. With the right tips and proper fit, the bass feels really tight, and it slams really well. No complaints at all.
Sweet Mids and Decent Staging:
The midrange on the Butastur IEMs is sweet and well-balanced. Vocals are such a charm on these IEMs—emotional and engaging. The staging and imaging are both very decent, and what's most notable is the seamless cohesion among different frequencies. There's no sense of frequencies stepping on each other; they each have their space to shine. Contrary to concerns about thin sound, the Butastur IEMs, especially when paired with high-end setups like the Lotoo Paw Gold Touch and Aroma amp, produce notes with enough weight and body. This results in a rich and immersive audio experience.
Conclusion:
Tuning is the real secret sauce.
In my time with the Butastur, it became clear that this product is not just another IEM packed with a high number of drivers. It's a testament to the importance of good tuning. If an IEM is well tuned, it can sound really amazing. Butastur elevates your audio experience by providing superb resolution and preserving the authentic timbre of the music. These IEMS have been designed to impress, to break the myth that only kilobuck and flaships can sound good (still not a kilobuck killer). Butastur truly shines when paired with high-quality sources, such as the Lotoo Paw Gold Touch and Aroma amp. They deliver performance that exceeds their price range, making them a Mid-Fi King in their own right. It has pretty much everything you look for in a great IEM. It If you're in search of IEMs that offer exceptional value for money, the Butastur IEMs are undoubtedly worth considering. Quite an achievement for an IEM priced at 500–600 USD.

Noble Audio Ragnar does not need any introduction. It has been one of the most revered iems in recent times. It’s really great to see Noble Audio pushing their boundaries, with each and every release. I have a Kublai Khan with me, and I am in absolute love with the Kublai. One of my dear friends acquired a Ragnar few months ago, and I happened to demo the unit multiple times in the last month. I will be sharing my views on Ragnar, and I hope they will resonate with those of many other reviews.
Specs:
2 x Dynamic Drivers for Lows
2 x Balanced Armatures for Midrange
2 x Balanced Armatures for Treble
4 x Electrostatics
Fit:
Ragnar, like many other Noble Audio IEMs, has a big shell, but it has a very good and comfortable fit. A couple of my friends mentioned that they have issues with the fitting of Kublai Khan. Kublai Khan fits very well, and since it is a very lightweight monitor, I absolutely have no issues with it either. Similarly, the Ragnar, even if the size is on the larger side, has a light weight and fits well. Also, the tip rolling becomes handy if you find a tip that helps you with a decent insertion, Ragnar will fit really well. Ragnar has a wide nozzle, and a tip with a long stem and wide bore sits really well on it. It's funny to note that in the winter, the aluminum shell is too cold sometimes.
Also worth mentioning is the cable that comes with Ragnar. It is much better than the one that comes with Kublai Khan and many other high end IEMs. The stock cable on Jewel is just meh. I am sure most of the people owning the Jewel do not use it's stock cable. I also tried a couple of different IEMs with the Ragnar's stock cable and found it to be really good in terms of sound. Not that it adds a lot to the overall quality of sound, but you will not consider discarding it either. A well-done job, Noble Audio.
Sound:
All the sound impressions are based on the different listening sessions I had on the following set-ups:
1. Lotoo Paw Gold Touch + Ragnar on stock cable
2. Lotoo Paw Gold Touch + Ragnar on stock cable + Aroma A100tb
3. Lotoo Paw Gold Touch + Ragnar on PWAudio First Times + Aroma A100tb
4. Earmen Angel as DacAmp + Aroma A100tb
5. Sony WM1ZM2 + A&K PA10 + Ragnar on PWAudio First Times (with Shielding)
I will talk about all these combinations later. First, let's try to understand what the general characteristics of Ragnar are.
Those who have demoed or owned Ragnar already know that there are only a very few IEM‘s that come close to Ragnar in terms of technicality, detailing, resolutions, and imaging. Ragnar is a real beast when it comes to detailing. Every thing, every sound, comes out quite clear and distinct. I think this is the biggest prowess of these IEMs; it's something you will notice as soon as you have put them in your ears. You can hear new things in the music, or something that may sound muted on other iems would come to life with Ragnar. It has such a spacious sound stage - wide and tall - it will leave you stunned. Also, the sound is very analytical in the sense that it does not add any color and produces sound as the tracks intend it to. These few characteristics make Ragnar really different from the others in this sense. It has its own character, and it sticks to it. Ragnar does not pretend to be a musical or fun-sounding iem rather, it has it's own type of potential.
Highs:
In my opinion, Ragnar has very impressive highs. I have found that if the EST drivers are properly tuned and implemented, the IEM will have impressively high frequencies. To me, Ragnar is a true treble monster with superb extension and airiness. If for someone the highs are sharp, tip rolling comes really handy to tame the treble, if at all required. I did not find any treble spike or any harshness as such. I am treble sensitive and do not tolerate brightness in the iems, but Rangnar did not bother me at all. I think this is more because of the set up that I was listening the Ragnar on. Also, the stock cable adds a bit or two to the brightness of the IEMs. I think if you give enough power (read a good source) to Ragnar, the upper frequencies become cleaner and more detailed, and there should be no issues as such. The high frequency becomes more enjoyable with a better chain.
Lows:
The lows in Ragnar are lean by my standards, and a lot of people find them the same way. If two dynamic drivers cannot produce enough bass, then what can? With a lean bass and an airy, detailed sound, sometimes Ragnar may come across as a thin or sharp-sounding IEM. If your source (DAP) has a very normal amp section, you will certainly not enjoy Ragnar a lot. I found that if enough power is given to the Ragnar, the lows get some weight and there is enough kick in the lower end, which makes the Ragnar much more enjoyable. Also, throwing a good cable as FTs or 1950s adds to it's tonal weight, and the bass response gets better. The sound is more open with a good cable.
Mids:
With such great resolution and detailing, the mids have to be amazing. The wide and tall soundstage and great imaging help the instruments play very separately, and everything sounds really sweet. I find the mids to be positioned exactly where they should be - not far behind and not too much in the front. The vocals are crisp and sharp. You will feel intimate with the singers, as if they are singing softly in your ears with all the voices directed towards you. On the stock cable, it may not sound as full as many would like it to, but the better the source you have, the more the mids shine. All in all, there is nothing to complain about here.
Comparisons:
To be fair, Ragnar has a distinct characteristic that I do not find fit to compare to other IEMs. But just for the sake of it, I would say that in terms of resolving capabilities, I think it is better than the XE6 and Radon6. Jewel is definitely better at resolution than Ragnar. If given a full-blown chain, Ragnar comes quite close to the Jewel but does not surpass it. Ragnar may have done better on the highs, as the extension is superb. In terms of soundstage, Rangnar has better depth and height and has a three dimensional character, which the XE6 and Radon6 do not have or are lacking in. Both the FiR Audio iems have better bass (default), and Ragnar never reaches the surreal level of bass from XE6 and Radon6. In my opinion, Radon6 probably has the best bass on any iem.
About different sources:
To me, the best chain for Ragnar is - Lotoo Paw Gold Touch + Ragnar on PWAudio First Times + Aroma A100tb. I am very sure there are only a very few chains with a better or equally great sound than this. The LPGT replaced with the Sony WM1ZM2 is equally good-sounding, if not better. Both of these DAPs are on par when it comes to resolution capability. The First Times with Shielding takes Ragnar to another level by opening up the sound, giving it a fuller midrange, and adding to the overall dynamics. There is a better sense of staging with this cable. No wonder it is one of the best cables on the market. The Aroma A100TB amp is a beast, and it gave a new life to Ragnar. It adds a lot to the overall dynamics and tonal weight. The bass response became really amazing, and who says the bass on Ragnar is lean. The overall bass response of this amp is much better than the A&K PA10.
I have an interesting story to share. This unit, which I borrowed for auditions from my friend, was put on sale. He might have used it for nearly 6-7 months, and he was somehow not enjoying the iem a lot on his chain (Sony WM1ZM2 + A&K PA10 + Ragnar on PWAudio First Times (with Shielding)). One evening, I sent him my Aroma A100tb, and things changed. He was so happy with what the amp had done to Ragnar's sound. He was so thankful that I saved him from selling off the unit and saving time for further exploration. I am sure it will take a lot of effort and auditioning if someone wants to go for the next IEM after Ragnar, and there aren't many IEMs. If you have used Ragnar on a good setup, consider yourself spoilt.
I am not sure why some users drive the Ragnar with a dongle. Dongles do not have enough power and resolution to work well with Ragnar. It's just undermining the immense capability of the iem.
Conclusion:
Noble Audio Ragnar is not everyone's cup of tea. I feel that the makers made such a technical and capable IEM with intention. You have to be sure if you want to get one or not. To all who consider owning it: please make sure to audition it well. Also, it's very important to know that Ragnar needs a proper chain - a good source, an amp (may be), and a good cable - and then you will not consider anything else for a long time. Ragnar is an IEM with infinite capability, and as a listener, you have to make sure that you get the best of it. There has to be absolutely no weak link in the chain, because that would really put Ragnar in the back seat. Contrary to some views, I do not find Rangnar to be cold and thin. I have enjoyed my time with it a lot.

Great review! Agreed that it is not for everyone and it is source picky!
Kohinoor: It is one of the largest-cut diamonds and one of the most beautiful diamonds in the world.
Aroma Audio Jewel:
Aroma Audio Jewel is currently among the best IEMs on the market, and it does not need an introduction. People have gone crazy listening to them, and I too was hit very hard. The moment I put them in my ears, I was so unbelievably absorbed, it really took me by surprise. This IEM is at a totally different level; I'm not sure if anything at all compares to the Jewel. I know it costs a lot, so I was expecting something good but not this good. It is a freaking all-rounder. It is not a beast of any particular frequency range - you will not say that it’s a bass monster or an iem with the most impressive treble, the most beautiful mids, or the one with the best soundstage; it is not something that has any of these particular characteristics. So, how in the world does it sound so crazy and amazing? I think it’s a freaking all-rounder. A versatile iem, which Jewel is, is something that touches everything that produces great sound for an iem and stitches these characteristics so beautifully that the whole world becomes musical. I am not joking when I say all this. This IEM will ask you to close your eyes and live in the moment because nothing has been so musical to your ears and brain. Is it an IEM with a perfect 10/10 score , I am not sure, but yes, it may be the most musical of all. Forget the technicalities and the pin-pointing analysis; it will not let you do any of that. It just draws your attention to music and asks you to enjoy it.
Sound:
Jewel is quite easy to drive. It does not demand a lot of power, and it sounds beautiful with every source, be it an iPhone, a dongle (Ru6), some very old basic DAP (Fiio M11), or a very high-end set-up. Of course, if you hook it up with a better source, it sounds better and shines a lot. When I had Jewel with me, along with many other sources, I also tried it through: Sony WM1ZM2 + A&K PA10 amp + PWAudio First Times Shielding Cable. Imagine the delivery - unimaginable, right? Goosebumps and Musical Nirvana! Believe me, your chain does not need to be so efficient. I think Jewel just needs a good resolving chain - some good DAP with enough power and resolution - DX320 should be good enough.
Some details down here:
Highs:
Jewel has an outstanding treble extension. It's just a bit on the brighter side for me, but nothing to complain about at all. It has super excellent highs - it’s sharp and precise - with no sibilance, harshness, or shrillness. Jewel has amazing details, accuracy, and clarity on the higher end. There is a great sense of airiness. There is this song I found that challenges the treble handling capability of IEMS. I try it on all the new IEMs that I come across and believe me, the Jewel handled it really well, though I never listen to whole of this song (the highs are too sharp on this song; please skip if you really have issues with hot treble).
Mids:
Mids on Jewel are very natural. As resolving and sweet as it can get. You will enjoy every bit of the delivery of sweet mids from Jewel. The fact that frequency ranges are so beautifully and distinguishably produced that the transition to/separation of mids from other frequencies is amazing - as if the mids take a front seat when it is required. Mids can not sound more beautiful than this, even if it is not tuned to be a mid-centric iem. Vocals are forward (with enough emphasis), with enough weight and texture. The emotions from the vocals come out as intended. Vocals have life, as simple as that.
Lows :
Jewel has a perfect amalgamation (balance) of great quality bass and enough quantity of it. There is enough punch and slam, and Jewel's bass is not at all boomy - quality of bass. Bass is clean, controlled, and has fast decay, and all of this does not eat away or eclipse the other higher frequencies and details. Jewel delivers bass when it is demanded - in perfect quantity. You won’t be left wanting for more bass with Jewel, that’s for sure. If you are looking for a bass monster, better look for the Radon 6; my goodness, what haunting and deep bass there, probably the best bass on an iem!
Staging:
A great strength of Jewel is its imaging and separation of how instruments sound. It is beyond stunning. In a song, I can sense where people are standing and playing instruments. It creates a layout of the arrangement of all the instruments in your head. Instruments play quite separately from each other (yet not very far away). For example, the sound from the acoustic guitar in the left ear, which starts at 0:26 in the song Hotel California is so incredibly detailed and pronounced - it's just unbelievable - seems like the sound etches and tickles your brain and senses. Goosebumps! I know Jewel has an amazing resolution, best of the best resolutions. The things that are sort of faded, muted, or shadowed and not very pronounced on other IEMs just come to life on Jewel, and you can imagine how beautiful such things can be. But is it not too detailed?
Conclusion:
To sum it up, Jewel is a real gem of an IEM. For obvious reasons, a lot of people find it to be the best-sounding pair. The best part is the delivery across all the frequencies and the coherency in how all the frequency ranges are handled. Everything out of Jewel sounds magical, irrespective of genre. Every frequency is given enough weight as if the IEM knows what is the best delivery at that point in time, and as humans, we always look for this. This creates a great sense of musicality. What could sound better than Jewel? I wonder, and then I say I do not want to know. For this reason, I did not even mention any comparisons because I have not heard a better-sounding IEM - FiR Audio XE6, Noble Ragnar, or Empire Ears Odin - they all sound good, but they are behind the Jewel. Aroma Jewel is a jewel in real literal terms - a refined and polished precious iem. A Kohinoor among all the gems.

Mids can not sound more beautiful than this, even if it is not tuned to be a mid-centric iem. Vocals are forward (with enough emphasis), with enough weight and texture. The emotions from the vocals come out as intended. Vocals have life, as simple as that.
Lows :
Jewel has a perfect amalgamation (balance) of great quality bass and enough quantity of it. There is enough punch and slam, and Jewel's bass is not at all boomy - quality of bass. Bass is clean, controlled, and has fast decay, and all of this does not eat away or eclipse the other higher frequencies and details. Jewel delivers bass when it is demanded - in perfect quantity. You won’t be left wanting for more bass with Jewel, that’s for sure. If you are looking for a bass monster, better look for the Radon 6; my goodness, what haunting and deep bass there, probably the best bass on an iem!
Staging:
A great strength of Jewel is its imaging and separation of how instruments sound. It is beyond stunning. In a song, I can sense where people are standing and playing instruments. It creates a layout of the arrangement of all the instruments in your head. Instruments play quite separately from each other (yet not very far away). For example, the sound from the acoustic guitar in the left ear, which starts at 0:26 in the song Hotel California is so incredibly detailed and pronounced - it's just unbelievable - seems like the sound etches and tickles your brain and senses. Goosebumps! I know Jewel has an amazing resolution, best of the best resolutions. The things that are sort of faded, muted, or shadowed and not very pronounced on other IEMs just come to life on Jewel, and you can imagine how beautiful such things can be. But is it not too detailed?
Conclusion:
To sum it up, Jewel is a real gem of an IEM. For obvious reasons, a lot of people find it to be the best-sounding pair. The best part is the delivery across all the frequencies and the coherency in how all the frequency ranges are handled. Everything out of Jewel sounds magical, irrespective of genre. Every frequency is given enough weight as if the IEM knows what is the best delivery at that point in time, and as humans, we always look for this. This creates a great sense of musicality. What could sound better than Jewel? I wonder, and then I say I do not want to know. For this reason, I did not even mention any comparisons because I have not heard a better-sounding IEM - FiR Audio XE6, Noble Ragnar, or Empire Ears Odin - they all sound good, but they are behind the Jewel. Aroma Jewel is a jewel in real literal terms - a refined and polished precious iem. A Kohinoor among all the gems.

Excellent review, loved the Kohinoor analogy but the build quality is far far from it unfortunately.

Very well-written review. Having auditioned the set, I can relate to your review. It's a beautiful sounding set. absolutely amazing, just pricey hehe.

Excellent review, thank you !
Introduction:
I had been eagerly waiting for the opportunity to audition the Noble Audio lineup, particularly the Sultan, Kublai Khan, and Ragnar models. Fortunately, a couple of friends within the audiophile community recently acquired the Kublai Khan. They kindly allowed me to borrow one of the units for a few weeks, and this review is based on my experience with the Kublai Khan during that time.
Nobel's commitment to providing a fantastic unboxing experience for users is truly admirable. The Kublai Khan, in particular, impresses with its generous packaging, including a sizable box, a good selection of eartips, and a convenient small pouch. This thoughtful approach reflects the brand's attention to detail and consideration for their customers. In contrast, brands like 64Audio, such as the Fourte, do not invest as much in the packaging, potentially missing an opportunity to enhance the overall user experience. I was very very dissapointed when I unboxed my Fourte. It has nothing useful inside the box other than the iem.
Build:
Noble Audio is renowned for its commitment to crafting exceptional in-ear monitors (IEMs) with top-notch build quality. They go to great lengths to ensure their IEMs are built to the highest standards, resulting in a product that exceeds expectations. Kublai Khan is no exception. Its ergonomic shape ensures a snug fit, while its sturdy construction guarantees long-lasting performance. KK features a sleek and modern design, highlighted by a 3D printed resin shell and an acrylic acetate faceplate adorned with the stylish logo. Even if it looks a bit big in size but has no fit issues at all. It needs a good fitting tip to get the best sound output and comfortable long listening. I am using Azla SednaEarfit Light (S).
The cable accompanying the Kublai IEMs is of decent quality, offering good performance and durability. When compared to the cheap-looking and flimsy cables often found with other IEMs, such as the 64Audio Fourte or Aroma Audio Jewel, Noble Audio's cables consistently stand out for their superior standards. Users will not find themselves itching to replace the cable as soon as they start using it. I am not sure if I have ever heard a single song on Fourte’s cable; I remember ordering a cable even before I bought Fourte.
Sound quality:
Thanks to the sophisticated driver configuration, Kublai Khan has very clean, precise, controlled, and fast sound reproduction. Overall, it is very musical and delicious sounding iem. The soundstage is quite wide on the Kublai, and it has even better imaging. it produce precise and detailed sound reproduction while excelling in transparency and resolution.
To me, it is an i-will-do-it-all iem. In simple terms, KK is an iem that makes every genre sound good. You enjoy metal, rock, jazz, and acoustic music equally on these IEMs. This is what they call an effortless sounding iem and an all-rounder. No wonder it has instantly become a favorite iem for many people.
Highs:
The inclusion of a piezoelectric super tweeter enhances the treble response, providing excellent clarity and extension in the high frequencies. While the highs are well-controlled and well-extended, sometimes it may be bit bright for some. However, with a good cable, the brightness can be easily tamed. I tried the KK on PWAudio 1950s cable, and the extra brightness was almost negligible. With the other cable, Effect Audio Eros S and the stock cable, there is some brightness, which sometimes may be a bit more for a few folks. Also, with some chains, the treble can be very sharp (ex: on my Earmen Angel). KK needs the warmth and love of a warm source, and it shines like a star.
Mids:
Good and detailed mids give this IEM great musicality. The mids are not too forward or too back—just where you want them to be. The midrange frequencies are nearly perfect, presented with more emphasis on the lower mids without eating up the upper mids. Vocals sound immersive and maintain a great body and weight. There is a great level of clarity, and instrument separation is so good that it makes the mids shine a lot.
Lows:
Lower ends in the KK are not about powerful slams, punches, and booms, they're rather about quick, fast, and precise attack. I think it’s one of the most loved aspects of this IEM, and this is the kind of mature low end a lot of people look for. The bass is not as impactful as bassheads would like, but it’s just enough not to turn your head away.
Comparisons:
64Audio U12t:
Kublai is definitely more musical compared to the more laid-back characteristics of the U12t. The Kublai Khan offers clearer, snappier, and sharper sound production while On the other hand, the U12t has a slightly more relaxed approach. The low ends in KK are better produced, which is obviously because of BCD. The U12t's all BA drivers do not produce that precise bass, although it's not something I find lacking in the U12t. Both IEMs can complement each other, and the user can put them to use based on different moods. In terms of soundstage, both IEMs are on par with each other, providing a similar sense of spatial positioning and imaging, but I would still say Kublai may be a bit better here.
FiR Audio Radon 6:
I think these are just two different IEMs, and the price difference is also considerable—nearly 600–700 dollars. Radon 6 has amazing bass and sub-bass, something that is quite distinct, and I am sure not a lot of IEMs can beat it in this department. So in the lower frequencies, RN6 is the clear winner and may be the reigning king of all IEMs. But KK is definitely more musical, and the other frequencies (mids and highs) are done better on KK. In terms of soundstage and resolution, I would say RN6 has the upper hand. Also, It’s worth mentioning that Radon has a small shell and an excellent fit, and those who find KK’s shells big can certainly find RN6's fitting awesome. RN6’s build Quality is also too good.
Noble Audio Sultan:
I find it surprising that many people do not find the Sultan IEM impressive, as I personally had a great experience with it. I can acknowledge that the Sultan has a warm and dense sound signature, which may not appeal to everyone who prefers a cleaner sound like the Kublai Khan offers. The Sultan's denser and more intimate sound lacks the openness and airiness that the Kublai Khan provides. That being said, I still consider the Sultan to be a highly capable IEM, but I do recognize that the Kublai Khan is a more refined and better-tuned option.

Conclusion:
- The Kublai Khan is an all-rounder and can handle all types of music equally well. It will ask you to explore genres.
- Awesome slams and precise bass make EDM numbers sound awesome.
- Good vocals and midrange make listening to acoustics a great experience.
- The energy of KK makes Metal sound really enjoyable - without the fatigue part.
- The airiness, big stage, and controlled treble make Jazz songs shine a lot.
- It's easily one of the best IEMs in its price range. One should look no further than this.

Introduction:
AFUL, now a prominent Chinese company, has garnered significant acclaim for its production of high-quality in-ear monitors (IEMs), the Performer5. This exceptional IEM has garnered a considerable amount of attention and praise within the passionate audiophile community. Now, with the release of its successor, the Performer8(P8), AFUL has managed to raise the excitement levels even higher. The Performer8 has captivated enthusiasts and experts alike, as it surpasses expectations by delivering exceptional sound quality that truly does justice to all aspects of the audio spectrum, including the highs, mids, and lows. It is particularly noteworthy that this remarkable performance is achieved at a price point that far exceeds what one would typically expect, making the P8 an outstanding value proposition.
Sound Quality:
Treble:
The treble response of the P8 is remarkably smooth and exhibits excellent extension. It manages to strike a perfect balance by delivering an ideal amount of airiness without any harshness or sharpness that could cause listener fatigue. The treble reproduction is skilfully executed, allowing it to reveal intricate details in the music with exceptional clarity. The Performer8 excels at presenting these details in the best possible manner, ensuring that each subtle nuance and shimmering high-frequency element is conveyed with precision and finesse. This level of detail retrieval adds an extra layer of immersion and engagement to the listening experience, allowing listeners to fully appreciate the intricacies and nuances within their favourite tracks.
Mids:
The midrange performance of the P8 is characterised by a delightful sweetness that is truly pleasing to the ears. There is a notable presence of warmth in the mids, which contributes to a rich and inviting sound signature. In particular, vocals shine exceptionally well on the P8, delivering a captivating and emotionally engaging listening experience.
However, it's worth mentioning that there are instances where the bass slightly intrudes into the midrange frequencies, IMO. While this doesn't significantly detract from the overall quality, it's an area that I felt had some scope for improvement. Fine-tuning the balance between the bass and midrange frequencies could potentially enhance the separation and clarity of the midrange, allowing vocals and other midrange elements to truly stand out without any hint of bass interference.
Despite this minor observation, the overall performance of the P8's midrange remains highly enjoyable and commendable. The sweet tonality, coupled with the touch of warmth, creates a very immersive experience, particularly for genres that heavily rely on vocal presence and midrange instruments.
Bass:
The overall bass performance of the P8 is highly satisfying, providing a smooth and enjoyable low-end experience. The iem delivers clean, deep, and impactful bass that adds a sense of richness and fullness to the music. The sub-bass reproduction is particularly impressive, creating a satisfying foundation that adds weight and depth to the audio. P8 captures the low-frequency elements with precision and control, ensuring that each bass note is articulate and well-defined. Whether it's the rumbling resonance of a kick drum or the reverberating thump of a bass guitar, the Performer8 faithfully reproduces the low-frequency content, allowing listeners to fully immerse themselves in the rhythmic and energetic aspects of their favorite tracks.
Others:
P8 boasts a nice build quality that instills confidence in its durability and longevity. The high quality resin gives a solid structure to the IEM, ensuring that it can withstand the rigors of daily use. The ergonomic design of the P8 contributes to a comfortable and secure fit, allowing users to enjoy extended listening sessions without discomfort.
While the cable of the P8 could be improved, especially when compared to higher-end offerings, it is important to consider the context of its price. Given its affordable price point, it's difficult to complain about the quality of the cable. It remains functional and reliable, serving its purpose effectively for everyday use.
It is worth noting that some enthusiasts may have preferred a balanced cable version of the P8. However, considering the competitive price of the IEM, the absence of a balanced cable option is understandable. AFUL has focused on delivering exceptional sound quality and overall value, ensuring that the P8 remains accessible to a wide range of listeners.
Conclusion:
Finding a product that strikes the ideal balance between cost and performance in the world of audio equipment can be difficult. The price-to-performance ratio of the Performer8 is simply exceptional. P8 manages to deliver a level of performance that far surpasses what one would typically expect at its price point. The fact that AFUL has been able to achieve such remarkable sound quality, while keeping the cost reasonable is truly impressive. The excitement and positive reception surrounding the P8 among the audiophile community have undoubtedly been influenced by this combination of high performance and affordability. I would encourage people to try this wonderful iem for its exceptional sound quality and value for money proposition.

I was definitely not impressed with bass performance of P8, coming from P5. But the treble and general detail quality is outstanding. If only they kept the bass quantity the same as P5, this IEM would be amazing. Major tuning setback, IMO.
Introduction:

Lows: One of the standout features of the FAudio Dark Sky is its impactful bass response. The deep, resonant lows are expertly handled, with the dynamic driver providing impressive bass slams that truly pack a punch. Despite the emphasis on bass, the Faudio Dark Sky maintains excellent control, preventing any muddiness or overpowering of the other frequencies. Whether it's the rumbling notes of a bass guitar or the thunderous beats of a kick drum, the Dark Sky brings a sense of cohesiveness and fluidity to the lower frequencies, providing a solid foundation for the music.

Comparisons:
Oriolus Isabellae
The Oriolus Isabella is awesome for its mid-range centric tuning, offering a natural and warm sound that is particularly captivating for vocal enthusiasts. Its single dynamic driver design provides a beautiful presentation of the human voice, showcasing a realistic and rich tonality. The Isabella excels in rendering simple acoustic music, allowing the listener to appreciate the subtle nuances and delicate details of the instruments. Its emphasis on the mid-range creates an intimate and engaging listening experience, making it a go-to choice for those seeking a captivating vocal performance.
On the other hand, the Dark Sky takes a different approach as an all-round IEM. While it may not excel in the vocal and mid-range aspects like the Isabella, it compensates by delivering amazing lower-end frequencies.

The choice between the two ultimately depends on the listener's desired sonic characteristics and the mood they wish to experience – the Isabella for relaxed and introspective listening, and the Dark Sky for a fun and energetic musical journey.
CampfireAudio Andromeda
The Dark Sky, with its dynamic driver configuration, offers a notable emphasis on impactful bass. It delivers a powerful low-end response that adds depth and weight to the music, creating an engaging and energetic experience. While the bass of the Andromeda may not be as impactful as the Dark Sky, it compensates by providing a more balanced and nuanced representation.

Overall, the Dark Sky impresses with its impactful bass and energetic sound, catering to listeners who appreciate a dynamic and bass-forward presentation. On the other hand, the Andromeda takes a more balanced and immersive approach, offering a larger soundstage, a sweeter mid-range, and a more refined overall musical experience. The choice between the two ultimately depends on personal preference, with the Dark Sky appealing to those seeking a bass-driven sound, while the Andromeda entices those who prioritize a wider soundstage, an immersive experience, and a sweeter mid-range performance.
Conclusion:
1. Solid and all-round performance; I cannot complain of any particular thing missing in the iem. And that bass is super addictive.
2. Try bigger tips for that perfect seal. You will realize how well it sounds only when you have a great, snug fit. My SednaEarfitLight size L did wonders.
In conclusion, the FAudio Dark Sky is a formidable contender in the realm of high-quality audio. Its powerful bass, clear midrange, and extended highs work together harmoniously to deliver an immersive and captivating listening experience. With remarkable resolution, clarity, and detail retrieval, these IEMs excel at recreating music with stunning realism. The elegant and lightweight design ensures a comfortable fit, complemented by the inclusion of premium accessories. The Faudio Dark Sky is truly an all-rounder, catering to a wide range of musical genres and pleasing the most discerning audiophiles. It is a testament to the dedication and craftsmanship of Faudio, to offer a product that exemplifies excellence in both sound and design.

While not many enthusiasts were familiar with FAudio's expertise, the Dark Sky came as a delightful surprise, showcasing the brand's mastery in audio engineering and craftsmanship. This IEM represents a significant leap forward, solidifying FAudio's position as a top-tier manufacturer capable of producing extraordinary audio devices.
FAudio Dark Sky is a true gem in the realm of audio enthusiasts, offering an immersive listening experience that is sure to captivate even the most discerning audiophiles. With its impactful bass, clear mids, and extended highs, this IEM (in-ear monitor) boasts a wide soundstage, remarkable layering, and imaging capabilities.
Dark Sky impresses not only with its exceptional sound quality but also with its thoughtful and high-quality accessories. The included cable, featuring both 4.4mm and 2.5mm terminations, ensures compatibility with a wide range of audio devices. The IEM also comes with a generous selection of eartips, allowing users to find the perfect fit for their comfort and sound isolation needs. The Dark Sky's build quality is top-notch, combining durability with a compact and ergonomic design that ensures a comfortable and secure fit for extended listening sessions.
Sound:
Highs: The extended high frequencies of the FAudio Dark Sky shine brightly without causing listener fatigue. The crispness and clarity in this range are truly exceptional, allowing intricate details to be effortlessly revealed. The highs are smooth, well-extended, and meticulously controlled, resulting in a delightful listening experience.
Lows: One of the standout features of the FAudio Dark Sky is its impactful bass response. The deep, resonant lows are expertly handled, with the dynamic driver providing impressive bass slams that truly pack a punch. Despite the emphasis on bass, the Faudio Dark Sky maintains excellent control, preventing any muddiness or overpowering of the other frequencies. Whether it's the rumbling notes of a bass guitar or the thunderous beats of a kick drum, the Dark Sky brings a sense of cohesiveness and fluidity to the lower frequencies, providing a solid foundation for the music. Bass lovers will find themselves in audio nirvana with these IEMs.
Mids: Contrary to some reviews, Dark Sky offers clear and detailed midrange reproduction. Vocals shine through with admirable presence and accuracy, allowing listeners to fully immerse themselves in the intricacies of the music. The midrange strikes a delicate balance between warmth and neutrality, ensuring that no instrument or vocal is overshadowed.
Soundstage and Imaging: The FAudio Dark Sky presents a large, open, and airy soundstage, allowing the music to expand beyond the confines of your ears. The instrument separation and layering are masterfully executed, resulting in a three-dimensional sonic experience. The imaging capabilities of these IEMs are commendable, providing precise placement and positioning of instruments within the soundstage.
Comparisons:
Oriolus Isabellae
The Oriolus Isabella is awesome for its mid-range centric tuning, offering a natural and warm sound that is particularly captivating for vocal enthusiasts. Its single dynamic driver design provides a beautiful presentation of the human voice, showcasing a realistic and rich tonality. The Isabella excels in rendering simple acoustic music, allowing the listener to appreciate the subtle nuances and delicate details of the instruments. Its emphasis on the mid-range creates an intimate and engaging listening experience, making it a go-to choice for those seeking a captivating vocal performance.
On the other hand, the Dark Sky takes a different approach as an all-round IEM. While it may not excel in the vocal and mid-range aspects like the Isabella, it compensates by delivering amazing lower-end frequencies. The Dark Sky exhibits a powerful and impactful bass response, adding depth and excitement to the overall sound. It offers a broader range of versatility across various music genres, ensuring an enjoyable experience for listeners who prefer a more dynamic and energetic sound.
In terms of fit and comfort, the Dark Sky holds an advantage. It provides a better fit, allowing for a secure and comfortable experience during prolonged listening sessions. The Isabella, however, is designed for relaxed listening, offering a comfortable and laid-back experience that caters to those seeking a more leisurely and immersive engagement with the music.
In summary, the Oriolus Isabella and the Dark Sky cater to different listening preferences and moods. The Isabella shines with its mid-range centric and natural sound, particularly enhancing vocals and simple acoustic music. On the other hand, the Dark Sky excels in delivering an all-round performance with its impressive lower-end response and better overall fit. The choice between the two ultimately depends on the listener's desired sonic characteristics and the mood they wish to experience – the Isabella for relaxed and introspective listening, and the Dark Sky for a fun and energetic musical journey.
CampfireAudio Andromeda
The Dark Sky, with its dynamic driver configuration, offers a notable emphasis on impactful bass. It delivers a powerful low-end response that adds depth and weight to the music, creating an engaging and energetic experience. While the bass of the Andromeda may not be as impactful as the Dark Sky, it compensates by providing a more balanced and nuanced representation. Andromeda, an all-balanced armature (BA) driver IEM, presents a controlled and accurate bass reproduction, focusing on precision and clarity rather than sheer impact.
One area where the Andromeda truly shines is its expansive soundstage. With its BA drivers and meticulous tuning, it creates a wider and more immersive soundstage, allowing instruments and vocals to be presented with greater separation and spatial accuracy. This enhanced sense of depth and imaging enhances the overall musical experience, bringing a heightened level of immersion and realism.
In terms of mid-range performance, the Andromeda is often praised for its sweeter and more refined presentation. The mids are characterized by a smooth and detailed rendition, elevating vocals and instruments to a level of clarity and emotion that captivates listeners. While the Dark Sky delivers a solid mid-range performance, the Andromeda's BA drivers excel in providing a sweeter, more nuanced, and overall more satisfying mid-range experience.
Overall, the Dark Sky impresses with its impactful bass and energetic sound, catering to listeners who appreciate a dynamic and bass-forward presentation. On the other hand, the Andromeda takes a more balanced and immersive approach, offering a larger soundstage, a sweeter mid-range, and a more refined overall musical experience. The choice between the two ultimately depends on personal preference, with the Dark Sky appealing to those seeking a bass-driven sound, while the Andromeda entices those who prioritize a wider soundstage, an immersive experience, and a sweeter mid-range performance.
Conclusion:
1. Solid and all-round performance; I cannot complain of any particular thing missing in the iem. And that bass is super addictive.
2. Try bigger tips for that perfect seal. You will realize how well it sounds only when you have a great, snug fit. My SednaEarfitLight size L did wonders.
In conclusion, the FAudio Dark Sky is a formidable contender in the realm of high-quality audio. Its powerful bass, clear midrange, and extended highs work together harmoniously to deliver an immersive and captivating listening experience. With remarkable resolution, clarity, and detail retrieval, these IEMs excel at recreating music with stunning realism. The elegant and lightweight design ensures a comfortable fit, complemented by the inclusion of premium accessories. The Faudio Dark Sky is truly an all-rounder, catering to a wide range of musical genres and pleasing the most discerning audiophiles. It is a testament to the dedication and craftsmanship of Faudio, to offer a product that exemplifies excellence in both sound and design.

Thank you. A fine write up I can second long owning both DS and Oriolus Isabellae.
Introduction:
For a very long time, I was in search of something portable—a dac/amp to use with my phone and laptop(at work). I had spent enough time with quite good daps in the past—Lotoo Paw 6K, Cayin N6ii, and A&K SP2KT—but somehow using a dap has never excited me a lot. I find it difficult to handle one more screen along with my phone and laptop. But these good daps have spoilt me in terms of good sound, always raising the bar when I look for something new. When Angel was launched in India, I was extremely excited. The reviews have been really good so far. Headfonia has said so many good things about it. I visited the India seller and spent some good time with the Angel before I bought it.
People at EarMen know tech and engineering. They originated from the house of Auris Audio - manufacturer of some super high-end tube amplifiers. EarMen has consistently proven its dedication to delivering exceptional sound quality, and the Angel is a testament to their commitment. With the Angel, EarMen has taken their ambition to new heights. As an eagerly anticipated addition to their product lineup, the Angel promised a level of sound quality that had me excited from the start. I was eager to witness just how high EarMen could score in terms of audio performance.
Sound Quality:
The most remarkable aspect of the Earmen Angel is its impeccable sound quality. The neutrality of its sound reproduction ensures a faithful representation of the audio, devoid of any unwanted coloration. What sets the Angel apart is its ability to strike a perfect balance between being impressive and natural. The audio reproduction is incredibly detailed, showcasing nuances and subtleties that might otherwise go unnoticed. Yet, despite this meticulous attention to detail, the Angel never veers into artificial territory. It maintains a sense of naturalness that allows the music to breathe and unfold organically. The absence of artificial enhancements/colouration allows the listener to truly appreciate the music as it was intended to be heard. Whether you prefer classical compositions, energetic rock anthems, or intricate jazz melodies, the Angel faithfully renders each genre with astonishing clarity and accuracy.
Lows: Lower frequencies are well-controlled, precise, and accurately reproduced without excessive resonance or lingering. This creates a clean and articulate low end response that adds to the overall clarity, rhythm, and dynamics of the audio. It has a tight and slammy bass with faster decay which makes the lower end much more enjoyable.
Mids: Mids are very sweet, natural and very very enjoyable. Vocals and instruments sound true to life, as if they were present in the room with you. There is a sense of realism and transparency, without any artificial enhancements or coloration. Mids are clearly Angel's strength.
Highs: There is an absence of distortion, muddiness, or unwanted artifacts in the high-frequency reproduction.The treble frequencies are presented with clarity and transparency, allowing intricate details and nuances to be heard without any smearing or veiling. The higher notes are presented with precision and without distortion, capturing even the finest details. Higher frequencies are well-tuned and smooth, without any harshness or piercing qualities that could cause listener fatigue or discomfort. Overall there is an airiness and spaciousness to the sound.
Power and Performance:
When it comes to power, the Earmen Angel stands out as the most potent option in comparison with devices of it's range. Its ability to drive headphones or speakers to their full potential is truly commendable. Whether you're using high-impedance headphones or demanding speakers, the Angel effortlessly delivers the required power, ensuring a dynamic and exhilarating audio experience. This feature sets it apart from competitors like the Mojo2 and Gryphon, ensuring that even the most demanding audio setups are handled with ease.
Angel can easily drive all the iems out there, in fact it is quite powerful for the iems. It can drive some easy-to-drive headphones but for more power hungry cans I would give it a miss.
Other Features:
1. The 5v/2A adapters charges it full in nearly 4 hours. The battery lasts for nearly 6-7 hours as it's promised. When the battery goes below 20%, the led blinks red which is really useful feature.
2. Whenever you switch iems, or turn on the device, the sound output resets to zero which again is very very useful.
3. The sound knob does a good job.
Comparisons:
With Mojo2 and Gryphon
I had the opportunity to compare the Earmen Angel with two popular models, Mojo2 and Gryphon. I must admit that the Angel exceeded my expectations and delivered an exceptional audio experience. With its neutral sound signature, fast decay, and impressive slams, the Angel proved to be a standout performer among its peers. Having compared the Angel with the Mojo2 and Gryphon, I can confidently assert that the Angel reigns supreme in terms of sound quality. Angel has a slightly faster and sharper/crisper sound than the two. While the Mojo2 falls short, with a laid-back presentation and a distinct coloration, the Angel maintains an open and clean soundstage that truly enhances the listening experience. The Gryphon, known for its impressive slam and soundstage, still doesn't quite match the power and overall performance of the Angel. The Angel's ability to deliver impactful slams, combined with its expansive soundstage, creates an immersive and engaging musical journey.
With Fiio M17
As an additional point of reference, I also compared the Angel with the Fiio M17. It is worth noting that the Angel performs on par with the M17 in terms of sound quality, providing a clean and transparent audio experience. However, the distinct coloration that is characteristic of the Fiio house sound is absent in the Angel. While the M17 may provide a unique tonal flavour, the Angel's neutrality showcases a purer and more accurate representation of the music.

Conclusion:
- Highly highly recommended.
- Sounds as good/better than as some of the daps I have tried: Cayin N6ii, LP6K, A&K SP2kT and the lower offering from the brand.
- If at all I would like anything to be better in the sound quality, it would be the soundstage. If it had any wider soundstage, Angel would have trumped even the best of daps in the market.
Note: This pair was bought from Hifigo. (Link)
Dunu is also known as Dunu-Top sound, It is a China-based earphone manufacturing brand, they offer a brilliant sounding pair of in-ear monitors with a strong and sturdy build quality. They have conquered the Chi-fi earphones market in the Mid and High price sections, they have products starting at around 150-200$ and their product range goes up to 1649$ with Dunu Luna as their flagship model. The Dunu Luna is the world’s first pure beryllium in-ear monitors, where not only the driver is coated with pure beryllium, in fact, the entire earpiece is made up of Pure Beryllium material.
Dunu Dk-3001 Pro is a five driver hybrid pair of an in-ear monitor from the brand which offers a single beryllium dynamic driver unit working together with four Knowles balanced armature drivers, it is said to be a purely balanced pair of in-ear monitor and today in this review we will find out how true that quote actually is.
Packaging and Build:
There are a lot of accessories included with DK-3001 Pro like there is a beautiful green colored leather carry case, three pairs of custom Spinfit silicone tips, a black colored box containing six pairs of silicone tips, several Spinfit gaskets to adjust the Spinfit tips, an airplane adapter, a 3.5mm-6.35mm headphone adapter, and cleaning brush. So, you see the box came with a lot of accessories, all of these are of great quality
The earpieces are made up of 316L stainless steel shells colored in black, even the ear nozzle is made up of black colored stainless steel material. The faceplate has a beveled design within which there is a Dunu logo on both the earpieces, They have printed R and L on the inner side of earpieces to differentiate between the right and left side easily. The earpieces have an extended side for MMCX connectors, the MMCX connectors are gold plated and seem strong and sturdy. Overall the earpieces have a very strong stainless steel shell, they look beautiful with a small form factor.
The wire is a kind of attraction in the package, Dunu actually makes this modular plug cables, and it is a single pure crystal copper cable with 4 strands, 2 on each side, the cable has got all kind of plugs included here like, 3.5mm single-ended, 3.5mm balanced, 2.5mm balanced, or 4.4mm balanced. So, it doesn’t actually matters which player or device you will be using with the Dunu, it has got a plug for any audio port on them.
Sound Quality
The pair surely needs a decent amount of burn-in after which it sounds a lot better. The entire frequency range feels buttery smooth and has a crisp texture to itself, let’s discuss different parts of the frequency response range in detail.
Lows:-
In Dunu DK-3001 Pro the lower end is handled by the beryllium dynamic driver unit, which provides a quick lower end, it offers a quick bass response, which has good thump to itself, has a depth feeling to it, the bass is not overpowering, so bass-heads don’t expect that soul-shaking heavy bass, but from what it offers it provides adequate amounts of bass, which is neither elevated nor it feels less, Drums in Dreams by Fleetwood Mac, Billie Jean by Michael Jackson have a clean and detailed depth to them. Listening to bass-heavy tracks like Bad Guy by Billie Ellish, Bet by Octavian, the sub-bass shows great rumble, the best part is tuning is so clean and crisp that the bass doesn’t overlap over the other frequencies and entire music output feels really clean and natural.
Mids:-
There are two Knowles Balanced Armature drivers which handle the Mids-High section in Dunu DK-3001 Pro, the pair actually shines in the Mids section for me, The vocals are pure bliss, listening to Cover sessions by Boyce Avenue, The Blower’s Daughter by Damien Rice was a mesmerizing experience. The vocals felt alive, there was a good depth to the voice of Hannah Reid from London Grammar, the heaviness of her voice gave me goosebumps the first time I heard it on the Dunu. The vocals are just perfect, acoustic details in songs like Hotel California by Eagles are rendered properly, there is so great clarity to those vocals, no muddiness at all. Sometimes I popped the volume to higher levels just to check if there is any kind of fatiguing but no, the voice didn’t fatigued even at higher volumes. The mids shine really greatly, I liked the mids performance the most in the DK-3001 Pro.
Highs:-
Again there are separate two Knowles balanced armature drivers working in the Ultra-High area of the frequency range, and believe me those instrument details, the instrument detail reproduction is simply unique, the music is reproduced so brilliantly that instrument details even in quick songs like those by Opeth, Kiss could be identified separately and very easily. There is no sibilance of any kind even at higher volumes, cymbals in Dreams by Fleetwood Mac showed great depth and detailing, Drums in Digital Bath by Deftones were really awesome. The highs portion showed me great extensions and soothing experience, I am actually very sensitive to harsh treble earphones, I couldn’t cope with sharp earphones for more than half an hour but with the Dunu DK-3001 Pro, I listened straight for up to 5 hours many a time.
The iems offer a brilliant wide staging, the staging shows great depth too, I listened to Binaural tracks by Yosi Horikawa to test the staging and imaging and its just superb. I listened to many MTV Unplugged Live recordings just to enjoy the wider staging.
It gives a brilliant instrument imaging, and one can easily recognize different instruments placements in live recordings.
Overall the Dunu DK-3001 Pro offers a brilliant, balanced, and natural sound output, with utmost clarity, crispy vocals, and rich details in the higher end with longer extensions. It shows great detail retrieval in the entire audio frequency range, provides a soothing and relaxed sound output. I simply loved the pair for its brilliant performance in the mids section.
Finally:
The Dunu DK-3001 Pro is an outstanding pair of in-ear monitor with a hybrid driver setup, offering a lightweight stainless steel design with a great quality modular plug type pure copper single crystal cable. A box full of accessories included in the package is a plus, the pair provides a never experienced balanced output with utmost claret and great mids performance. The detail retrieval in the treble section is just amazing, I tried almost all genres of music with the pair, with different DAP’s and it paired well with all the daps, but I loved it the most with the Dethonray DTR1. The pairing was just amazing, it was full of synergy. The pair shines a lot with powerful sources. I really enjoy this pair of mine, it is actually one of a keeper, I don’t think I will be selling this powerhouse of an earphone any time soon, feels worth every penny that I paid for it and even much more.
