Review Of The Kiwi Ears KE4​

Introduction​

Disclaimer​

Specification​

The KE4 uses a hybrid driver configuration with four drivers in total: two 10mm dynamic drivers in isobaric configuration and two balanced armatures: a super tweeter Knowles RAD 33518 and a full-range customised RAB 32257 connected via a three-way passive crossover and three independent sound tubes. The shells are made of skin-friendly resin and are larger than the normal IEM; the shell has a black tint, while the faceplate has a white marble-like design with kiwi ears carved in the center, resulting in a monochromatic, elegant, and simplistic look. As previously stated, the IEM shells are larger than the normal IEM; specifically, they are chunky. However, thanks to its ergonomic design, I did not experience any pain or a bad fit. The cable that comes with KE4 looks and feels more like the cable that comes with the Quintet, which is of top quality and performs admirably. The remaining accessories include three pairs of Kiwi Ears Flex eartips, a carrying case that looks like any other Kiwi Ears IEM case, and additional pairs of nozzle grills. According to the technical specs, the impedance is 28 Ohms and the sensitivity is 102dB. The frequency response ranges from 20Hz to 20kHz.

FiiO M15S - While listening to the KE4 with M15S, the response sounds intense and engaging; nevertheless, the response becomes much clearer and presentable as all of the elements occur synchronously. The treble has a more expressive response, whilst the midrange has a richer and more forward presentation, which actually brings that musicality into the mix with a pleasant and engaging response. The bass, on the other hand, has more engagement and intensity, resulting in increased exposure of bass quantity due to improved note characteristics and distinctiveness.

Conclusion​

Finally, whatever Meta tuning is, it is amazing and has a significant impact on how we perceive sound. Though the KE4 is not a dot-to-dot follower, it offers the ideal compatibility for audiophiles, whether they want a less shouty Harman tuning or a neutral with sub bass boost sound. I wanted to grasp the differences between what I prefer and what Meta tuning is, and I discovered that such a response is highly likely to be favorable to many others in the coming future. As a result, individuals looking for the safest option while also getting the best natural sounding IEM should certainly go with the KE4, which I strongly recommend.

Simgot EW300 Standard Version VS Simgot EW300 x HBB Version VS Simgot EW300 DSP Version​

Introduction​

To be honest, I never expected the EW300 to come in three different versions. I believe Simgot did the right thing by catering to each and every person's interests. Even if there is a distinct difference between the DSP and Standard versions, I will need to confirm whether the HBB version differs in sound in the tiniest manner conceivable. When it comes to the brand itself, I've been following and supporting SImgot for a long time, and I still believe that all of their goods are excellent in terms of sound and quality.I've always loved their EA series because of how they made me fall in love with the sound, even though it didn't sound like my preferred sound. However, I have been lucky enough to evaluate and test all three versions of the EW300 for this review, but before proceeding, I would like to clarify a few points.

Disclaimer​

*Since this unit tour was organised by the kindly people at Linsoul and Simgot, I am grateful to them. As I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link for all three version.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to all three IEMs as the same.
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate all three versions based on their performance, even though I will explain how they feels and seems physically and aesthetically.
*This time, my review will be different from my typical structure, and it may become more of a comparison, but I will try to cover all features of all three versions.

Specification​

In terms of shell shape and size, each of the versions are comparable, with the exception that the basic version is silver-finished and the other two have matte black paint. All versions share the same accessories, with the exception of the DSP version, which simply includes a USB-C terminating cable. All variants use the same driver configuration: a 10mm dynamic driver, an annular magnetic planar, and a 10mm ceramic piezoelectric driver. All models have heft and weight, and they are built like tanks. The form of the IEMs is comfortable enough for extended listening sessions, and with the correct eartips, I achieved a decent isolated seal. On a personal note, I think the Heart design on the right and the X design on the left are cool and unique in the world of IEMs. The cables that come with the normal and HBB versions are the same as those that come with the EA500 series, with 2 pin and 3.5mm terminations, but I believe they are lighter in weight; however, the DSP cable has an L-shaped USB-C and two pin termination with an attached mic. Other accessories include three pairs of eartips in three different sizes, a carrying box, nozzle rings, nozzle filters, and an additional pair of tuning nozzles with variable sound adjustments. Regarding technological specs, all three models have identical configurations. The impedance is 28 Ohms, with a sensitivity of 121dB (silver nozzle with red ring) and 119dB (gold copper nozzle with pink ring). The frequency response ranges from 20Hz to 20kHz.

Sound​

EW300 Standard Version & EW300 HBB Edition​

When it comes to responsiveness, both IEMs produce a more balanced sound with a strong emphasis on the upper midrange and bass, as well as the sparkling magic that Simgot has throughout the 12k-15k range, but I was startled to learn that the response was not what I expected. I mean this kind of response and how SIMGOT usually tunes their IEMs, the response tends to be more enticing and somewhat spicy sounding, but that is not the case with the EW300 versions. However, with DSP, there are some areas that I find highlighted, which I will discuss later in the review.

When it comes to the treble, the response has a more tonally favorable tone, which enlightens the whole response with tremendous detail, but at the expense of more rounded notes; instead of being sharp, the notes have a continuous and rich sound, but the pumps that SIMGOT DNA enthusiasts enjoy. The vocals and instruments retain the expressive and airy style that the EA series is known for, but the sound is more tonally balanced. The dip between the 5k and 8k regions could be the source of such a balanced and transient sound. When listening to one of my favorite tracks by Ai Higuchi, namely Akuma no ko, the same crisp and expressive vocals that sounded magical and stimulating when listened to EA1000 or EA500 retains here as well, and judging by the fact that her vocals do not offset that timbre while scaling high in these two pairs really brings the best performance I could've asked for, the same can be said about the instruments, as the balance between clarity and preserving the note's integrity is well demonstrated by the EW300 series' capabilities.

When it comes to the midrange, nothing stands out as lean or demeanor in a way that would bring any offensive traits into the mix, thanks to the 5k dip that thoroughly explores the 3k region without making it sound shouty and hot. I would also mention that the thickness of the lower midrange contributes to such a response. The vocals, in particular, have a more sophisticated presence, which I find captivating and beautiful. This quality allows both male and female vocals to sound unique, giving the impression of greater resolution than IEMs priced around or even higher than the EW300 series. Because of the distinction and clarity between the notes, the instruments, which are positioned slightly back, sound cleaner and crisper than I expected. Not only that, but the vocals and instruments sound deeper and richer as a result of the thick and clean-sounding lower midrange. Tracks like Burning by Hitsujibungaku sound clear and very opening, with all of the instruments and vocals happening at the same time. In fact, the female vocal retains that forwardness without losing that weight and magic, while the instruments set a great pace with precision and clarity, not overpowering any vocal notes.

When it comes to bass, I believe the way the tuning is done is best preferred or adored by many, and I believe that the EW300 is the only set in the IEMs they have released in the last two years that has such a bass response. I mean, I still love the bass quality and dynamics of the EA1000, but I still feel that if viewed from an overall perspective, the EW300 really soothes my heart. The bass has it all: rumble, punch, slams, and the faithful weight of bass notes, which essentially means that the sounds have a meatier and thicker response while being resolved and detailed. The bass emphasis is on the subbass, but as previously stated, it does not overshadow the midbass slams. Whether it is the bass guitar or drums, all have a good heaviness to the impact and richness to the notes. I can't claim the notes sound truly authentic, but they convey that sensation. For such a response, I believe the EW300 outweighs all IEMs that exceed its specifications.For example, in Kenshi Yonezu's Garakuta - JUNK, the drums have a good warmish and thick response, and the bass guitar slams are clear enough to be heard while providing good impact and exposure. The whole presentation of the tune is heightened by a rich and nostalgic component, since the song has a 2000s vibe.

When comparing the Red ring and Pink ring nozzles, I believe that the Pink nozzles provide a richer and warmer sound. I believe that folks who still believe that the upper frequencies contribute to spiciness will prefer the Pink nozzle implementation. The response is affectively tamed in the upper midrange, producing a warmish V-shape. I believe the male voices are more meticulously conveyed, and the instruments have more rounded notes, making the response sound smoother and richer, whereas the female vocals lack that openness and airy presence. Aside from that, there aren't any significant alterations in the mix.

EW300 DSP Edition​

When it comes to the DSP edition(Silver nozzle with red rings), there are a few areas where the response differs from how the EW300 sounds in analog presentation. The first is the implication of a different DAC&AMP integration, which provides a distinct response in terms of technicalities, most notably the stage. With the response expressed in front of you, it has a more mid-centric response, yet the bass sounds clearly defined, with better control over the note's intensity and weight. When it comes to the treble, this version has a more subdued expression of the treble, however it doesn't discard that airy presence in the region. Both the male and female vocals have less presence, Take the music Akuma no ko by Ai Haguchi; it sounds less broad and expansive, allowing her voice to lose their X factor. The mid range sounds more forwarded with the vocals being the star of the presentation, but the vocals sometimes sound shouty and the male vocals sounding a little lacking in the girth, when I heard Burning by Hitsujibungaku, her vocals felt like it didn't sound fuller and powerful enough while maintaining that distinction and clarity, I believe that her vocals became too much forward as at times the notes impacted negatively while producing a lean response, the instruments, on the other hand, seem clear and crisp but more intimate. As previously said, the bass has a less dynamic sound, but it is more defined and textured because to the control over the impact and presence. The impact is precise but not particularly strong, and the bass is well-controlled. For instance, Kenshi Yonezu's Garakuta - JUNK track sounded more precise and lost some of its warmth and richness, but the vocals were still more expressive and clear. Thus, overall, the response has a better balanced bass response and a more neutral sound.

The difference between the red ring and pink ring nozzles was apparent in how the midrange was presented. With the pink ring nozzle, female vocals sounded more vibrant, while the overall impact of the notes remained consistent. The response felt more neutral, yet the bass had a stronger presence, resulting in a slightly fuller and less lean overall sound.

Technical Performance​

In terms of technical abilities, I believe the EW300 series outperforms IEMs above its price range. I mean, if I look at the analog side of the EW300, the IEMs have great technicalities, and this has been the case with almost all SIMGOT IEMs, but I don't believe it differs significantly from the EA500 series, but I do believe that the clarity of the EW300 is nearly equal to the EA500 series. The soundstage has a wide width and depth due to precise imaging and good separation between the notes. By this, I mean that the notes are sharp and clear, and there is good contrast between the notes, which helps identify where the sound is coming from. Though I should emphasize that the response is more holographic, so it is closer than one may assume, but none come close to how well it performs among its contemporaries. In terms of resolution, both macro and micro details are expressive enough to sound detailed and express clarity. Even the note attack and decay are swift, allowing for a very defined performance, particularly in the bass region, without sounding overwhelming or bloated due to the quantity of bass that leaks into the lower midrange. When it comes to the DSP, I believe the response changes significantly in terms of note position and headspace; that is, the stage gets more forward and back of the head presented as the width gap is closed while the depth is better expressed. Overall, the response is one of the greatest I've heard in terms of technicalities, costing roughly $70.

Sound Impressions ​

Sources​

As previously indicated, the DSP version employs DAC&AMP. I have clearly stated how it sounds when compared to the Standard and HBB versions. I will only discuss my impressions of the analog version below.

Sony WM1A - While listening to the WM1A with the IEMs, the response sounded wider and more spacious, while the midrange was smoothed and balanced, and the treble became more present in the mix, resulting in a more sparkling but not sharp sound. The response was not very strong or dramatic, with each note hitting sounding light, but the overall presentation sounded realistic and spacious. The bass sounded fuller, richer, and more powerful. There are times when the presentation of the singers and instruments seems genuine and lifelike.

FiiO M15S - While listening to the WM1A with the IEMs, the response seemed very clean and resolved, and the bass sounded much more controlled while retaining the same heaviness and impact but with greater precision. The upper frequencies seem more appealing because the treble provides a more forward presentation, yet the midrange maintains the same presence. Though I find the response to be more intimate and revealing. The notes sounded less rich and energetic, but the overall response was clear and detailed.

Conclusion​

To summarize this review, I believe SIMGOT has always demonstrated potential in each and every product they have launched, and now that it comes to the EW300 series, I am really impressed with the dedication, hard work, and patience required to develop the best sounding IEM under $100 in my opinion. In fact, I believe the EW300 outperforms the EA500 series in terms of overall presentation; congrats to SIMGOT for developing this amazing beast. When it comes to the different versions, it seems that anyone interested in the HBB version would likely choose it for its exclusivity, collaboration, or perhaps the sleek black anodized finish, which I find particularly striking. However, if someone is seeking the best sound under $100, either version would be a solid choice. That said, those who prefer a Type-C connection and a matte black finish should definitely opt for the DSP version. In my opinion, the DSP version offers the best value for money, as it allows you to use any two-pin 3.5mm analog cable and still achieve the same tuning as the HBB and Standard versions.

Conclusion​

Finally, by releasing Canta, Kiwi Ears has embarked on a one-of-a-kind journey to change the way drivers are implemented. I believe they have accomplished what BA's implemented IEMs have been attempting to achieve, either by being patiently tuned or implementing various technologies that ultimately cost a lot of money to produce a great sounding IEM. As a result, even though I believe the tuning is still a little off from what I believe it will sound like with more research on the implementation of micro planars, I consider Canta to be a fantastic achiever and a great sounding pair of IEM. I believe that folks who loathe BA timbre or that sharp metallic timbre would absolutely adore these, so I wholeheartedly recommend them.

Review Of The SIMGOT SuperMix 4 ​

Introduction​

Recently, SIMGOT has been releasing amazing products; they have also made their international debut in a variety of categories and even released their flagship IEM. The Chinese company is well-known for specialized in the production of electro-acoustic devices, such as DACs and AMPs, headphones, and IEMs. As their ardent supporters, I get the impression that they are promising quality and preservation to their devoted fans and followers. The brand has recently begun developing and releasing various types of IEMs that use multi, tribrid, and quadbrid driver configurations. I was recently fortunate enough to get my hands on one of the newly developed quadbrid IEMs known as the SuperMix4 for review, but before we go any further, I'd like to clarify a few points.

Disclaimer​

Specification​

One custom 10mm polymer nano-diaphragm dynamic driver, one balancing armature, one piezoelectric driver, and one micro planar driver are all used in SuperMix4's quadbrid driver design. These drivers are coupled via an RC four-way crossover. The IEM has a metal finish faceplate and an opaque, skin-friendly resin body. The Shells are incredibly well-made and have a high-end, polished feel. There are no problems even after four hours of continuous wear because of the excellent fit and comfort. The included cable feels and looks fantastic in the hand and on IEMs, just like the cables that come with other IEMs like the EA1000 or EA500. The plug termination on the cable is the same two-pin, 3.5mm straight plug. A travel case and three additional pairs of eartips are also supplied as extras. Regarding the technical details, the sensitivity is 120dB and the impedance is 7.2 Ohms. The range of the frequency response is 20 Hz–20 kHz.

Sound​

Any Simgot IEM instantly strikes you for its forward-leaning, pointed presence in the high frequencies and rather realistic bass response, which together produce a response that is controlled and well-detailed. With SuperMix 4, on the other hand, the response is more oriented toward a well-balanced and regulated bass increase. SuperMix 4 employs a different methodology than SIMGOT's in-house sound typically does. The response is rich in tones rather than being technically flawless. Without sounding harsh or metallic, the response has a distinct, mature sound that is pleasant and soothing to listen to. These kinds of response remind me of other IEMs that are similar yet have different technical capabilities and driver constraints, such as Quintet, Monarch MKII, and Meteor. The best thing about the IEM is that because of the sub bass elevation, which is a little higher than the upper frequencies, the response keeps all of the warmth and weight of the notes even though the fr graph shows a tiny tuck about 300 Hz. Let's take a closer look at the sound to learn more about it.

Technical Performance​

Although there are several planar IEMs in this price range that are well defined in terms of details and clarity, the Supermix4's technical performance is not the finest, but it does sound better than any typical IEM in this price range. Now let's become more detailed.

Sony WM1A - The response sounded more balaned with exaggerated upper and lower treble, allowing for an expansive soundstage and more air, when listening to the SuperMix4 with WM1A. Despite this, the mid range had a somewhat relaxed tone, but the response was still forward enough to sound more full and open. The notes, on the other hand, had a more dense and thicker sound, which somewhat produced a drowned or hazy response. That might be because bass is seen as overwhelming, warmer, and having fewer powerful affects. Even yet, the reply sounded incredibly natural and rich.

FiiO M15S - No matter the region, the SuperMix4 with M15S response sounded forward in the presentation; this kind of response is more akin to a gentle V-shape sound than a balanced signature. The midrange sounds richer and more full-bodied, while the treble is prominent and has good details. The bass maintains its control while maintaining its energy in hits and impacts.

Tracks​

Conclusion​

Finally, I can't think of anything negative about the SuperMix4 if it isn't touted as the most technically best piece of equipment. Again, though, I think this pair is special and different at this price range. It won't offer you the best technical performance, but I think the sound is satisfying and a really unique approach to harman tuning. I'm grateful for the time and effort invested in creating such a wonderful and fulfilling-sounding IEM. Therefore, SuperMix4 is the greatest option available in this price range if someone wants a rich, pleasing sound that also allows for a calming, dynamic tone, and I wholeheartedly suggest these.

Review Of The TinHifi DUDU​

Introduction​

Disclaimer​

Specification​

The Dudu features a newly built 13mm planar driver on each side, with a dual voice coil custom planar diaphragm around a composite diaphragm. The shells are heavily inspired by TinHifi's T5S model, which is extremely ergonomic and easy to wear. The shells and faceplate are both composed of aluminum and are extremely lightweight. Because to its ergonomic design and comfy fit, I was able to listen to it for an extended period of time. These are available in two editions: standard and memorial. The standard model comes with only a 3.5mm cable, however the memorial edition includes both a 3.5mm and a DSP type-c cable capable of outputting 32bits/384kHz. TThe edition I received is a memorial edition, and both cables appear and feel flexible and well-made. Both cables have two pin connections, however the type-c cable has a microphone with a single button on it. The other supplied accessories are a variety of eartips. According to the technical specifications, the impedance is 32 Ohms and the sensitivity is 103 decibels. The frequency response ranges from 10 Hz to 20 kHz. Tin Hifi also promises an Android app for EQ'ing the IEMs to your particular preferences using the DSP cable soon.

Sound​

The DUDU's response leans toward a brightish V-shape, resulting in a nice detailed, lively response. I'm shocked to notice that the new planar IEM, aside from the T-series, sounds as excellent, if not better, than their recent planar releases, but that all relies on perspective. The overall response tends to sound revealing while also sounding more characteristic, a forward-like response with plenty of air and clarity. The treble and midrange sound forward and detailed, while attempting to balance the timbre and richness of the notes. The bass sounds realistic and hammering, with adequate focus in all regions. Though there are some parts where it adds a little too much to the mix, which many people enjoy, it is more than I desire. It is also worth noting that both the normal 3.5mm cable included with the IEM and the TYPE-C cable provide the same resolution. Let's go deeper into the sound to learn more.

FiiO M15S - When listening to DUDU with the M15S, the response was clearer and more precise, resulting in increased shoutiness and peakiness, as well as more forwardness and expression in the mix. The lean quality has improved, but the overall presentation appears to be more resolved and rich. The treble seemed more emphasized in the midrange, whilst the bass sounded more controlled but with a sharper punch and faster fade.

Review Of The TWISTURA D-Major​

Introduction​

Disclaimer​

Specification​

The D-Major features a single dynamic driver with a beryllium-plated dome and polyurethane suspension. The shells are mostly comprised of metal and hard resin, with the majority of the shell being hard resin and the faceplate being metal with a see-through glass in the center. The shell's form is unique, which may be an issue because the fit and comfort are highly dependent on one's ear design. For me, I was unable to achieve a pleasant fit, although the fit was isolated and, for extended periods of listening, it was slightly uncomfortable. The cable that comes with the IEM is average and is normal for IEMs priced around $50. The other accessories include an assortment of eartips, a carrying pouch, two additional tuning nozzles, and a dongle dac, which is unusual for an IEM priced under $50. According to the technical specifications, the impedance is 22 Ohms and the sensitivity is 108dB. The frequency response ranges from 15Hz to 37kHz.

Sound​

The D-Major has a mid-centric tuning, which results in a very open and forward sound, particularly in the upper midrange and lower treble. The notes have a particular quality that allows them to maintain their integrity even when overemphasized in the upper frequencies, preventing any offensiveness from developing. It's probable that the mix's unoffensiveness stems from the way the bass is adjusted, which has a powerful presence, and the treble, which is inconsistent and understated. In my opinion, it sounds more like ikko OH2, but with a more solid sound structure and base. The response is not well balanced, but it allows for a very powerful presentation of the instruments and vocals. When it comes to its competitors, I simply believe that it has a different tuning, which results in a different taste or presentation. Let's go further into the sound to learn more about it.

Sony WM1A - While listening to the D-Major with WM1A, the notes sounded the same, with nice weight and thickness, producing a natural-sounding timbre, but the treble felt enhanced, as if the unevenness had been removed, leaving only extensiveness and an airy response. The midrange seemed more tamed and balanced, while the instruments sounded more relaxed in response to the vocals. The bass sounded bigger and more prominent in the mix, adding warmth.

FiiO M15S - While listening to the D-Major with M15s, the notes sounded crisper and more detailed, with no offensiveness in the mix. The treble was more present in the mix, and the midrange sounded more open and spacious, with more revealing responses from both the vocalists and instruments. The bass felt a touch back in the mix, but it produced a more composite response.

Twistura DAC/AMP - While listening to the D-Major, the dongle dac that came with the package sounded efficiently powered, allowing for a more intimate and close-sounding presentation. The treble sounded inconsistent, with the midrange being more accentuated; yet, although offering a more strong mid-centric response, the treble sounded a little weak, particularly on the instruments, which felt artificial. In contrast, the bass sounded more detailed and better controlled, with a slight loss of warmth in this combo.

Review Of The 7Hz Five​

Introduction​

Following the release of numerous well-received IEMs, 7Hz, a Chinese firm that specializes in electro-acoustic products, has introduced a number of new products, including high-end dongle dacs and cheap to mid-tier IEMs. The company has produced a number of products, including Timeless, Zero, Dioko, and others, that are well-known among audiophiles. The brand offers a vast array of IEMs, has been around for a while, and has been successful in staying innovative, notably with the release of Aurora, their most expensive IEM, recently. Although I had the good fortune to get from 7Hz Five, a fresh and original perspective on IEM standards and ethics for review, though before doing so I would want to make a few clarifications first.

Specification​

A five driver arrangement of a single type driver is housed in The Five. Every dynamic driver is a specially designed 6mm driver, each with its own housing and an electrical crossover connecting them to deliver the needed favorable tuning by 7Hz. The shells have a metal faceplate and are constructed well, offering a good seal and fitting even though the nozzle is a little on the short side. I was still able to achieve an isolated seal by rolling the tip of the shell. This high purity silver plated oxygen free cable has a four strand parallel construction with 49 wires per strand. It is a two pin cable that terminates in a 3.5mm straight termination plug. The same kind of cable was also available with 7Hz sonus; it is incredibly flexible and of excellent quality. A zippered silicon travel case and an assortment of eartips are the other accessories that come with the package. Regarding the technical specifications, the sensitivity is 105dB and the impedance is 12 Ohms. The frequency response spans from 5 Hz to 40 kHz, with less than 0.5% of total harmonic distortion.

Sound​

Five's presentation is energetic enough to get your attention while maintaining a respectable level of quality and tonality, making it seem incredibly coherent and less tiresome overall. To be very honest, I think that the reason the IEM sounds so well is because of the way the drivers were implemented. Together, the five drivers produce a fluid, vibrant sound that is rich in fine technical details. Although the frequency response graph indicates that the lower mid range sounds a touch dull, the sound presentation leans toward a slight V-shape in my opinion. However, unlike other hybrid or multi driver IEMs, the warmth and richness are still present. Although the mid range is not overly central or upfront, it delivers a good balanced response where the vocals and instruments sound natural and enjoyable to listen to. The treble is lively and dynamic, which creates a fascinating response. The response sounds rich and dynamic with excellent coherence and a smooth response because of the large, powerful bass. To discover more, let's investigate the sound more thoroughly.

Technical Performance​

The Five's technical abilities are impressive but not the best in the competition. I mean, for an IEM to be tuned in such a way does bring that focus to tonality, but as it sounds with such a lively approach, one expects great technicalities that may satisfy but not surprise the listener. Let's be more specific.

Sound Impressions ​

Sources​

Sony WM1A - While listening to Five with WM1A, the response seemed smoother and richer, with a beautiful tone; the vocals felt more vibrant and forward in the midrange region, particularly the female vocals. Miyu Tomita's Paradoxes sounded natural and open without adding any heat or bite to the mix. The notes retained their integrity, allowing the treble to sound more smooth and nuanced. The bass, on the other hand, seemed a little muffled in the midbass region, allowing the subbass to become more rumbly and punchy with increased dynamics.

FiiO M15S - While listening to FIve with M15S, the response was shockingly forward in the midrange and well controlled in the bass. The response sounded more controlled and composite, and the quality of the sounds seemed significantly better with a tactile and quick presentation. The bass felt tamed, yet with more control over its presence.

Tracks​

Conclusion​

Finally, The FIve is a one-of-a-kind and innovative approach to how IEMs are seen in the audiophile community, and it is praiseworthy that 7Hz created the first five dynamic driver IEM. When it comes to sound, I think of people who enjoy a vibrant and engaging presentation with a smooth and cohesive response that sounds natural and favorable, particularly in genres such as R&B, Pop, EDM, and Jazz. As a result, these come with my highest recommendation.

Review Of The KZ AS10 Pro​

Introduction​

KZ has recently made significant improvements in the way they tune their products, thanks to increased feedback from their audiophile followers. As I previously stated, Kz was instrumental in starting my IEM journey and interest. I still believe that Kz truly bridges the gap between a casual listener and an audiophile, and I am living proof of this. albeit my personal experience does not show it, I believe Kz is still doing an excellent job, albeit I remain wary of their public relations. But, getting back to the review, Kz recently introduced a successor to one of their original products (AS10), the AS10 Pro, and I was fortunate enough to receive one for review, but before I go any further, I'd like to clarify a few points.

Disclaimer​

Specification​

Unlike the AS10, which featured a hybrid setup of one dynamic driver and four balanced armature drivers, the AS10 Pro has an all BA driver setup with five custom BA drivers. The shell has also been enhanced, though it feels a little larger, and the design is quite ergonomic, making it feel safe and comfortable on my ears. The shells also felt a little weighty, but there were no difficulties with comfort or isolation during longer periods of use. The faceplate on the shell is composed of metal and extends quite far over the shell; nonetheless, I believe that for a 5 BA configuration, the shell is excessively large.The cable that comes with the IEM is the standard KZ cable that they include with any of their mid-tier IEMs; it also features qdc connections on one end and a 3.5mm L-shaped termination plug on the other. The other included accessories are three pairs of silicon eartips and one pair of foam eartips. Technical characteristics include an impedance of 26 Ohms and a sensitivity of 109dB. The frequency response ranges from 20Hz to 40kHz.

Sound​

The feedback to any KZ IEMs lately has been increasingly positive; I recall testing the AS10 and not preferring the sound due to better competitors in the same price bracket. But now that I have the AS10 Pro, it appears that KZ has been actively working on their Planar, all BA, multi-hybrid, and other configurable IEMs. The AS10 Pro produces a bright neutral sound with sub bass boost, and for an all BA IEM with a weak predecessor, I believe it has vastly improved in terms of tonality and technical performance. The sound does not come off as offensive, though there are some instances where it adds some heat or sibilance. In other words, the sound incorporates BA timbre. Let's go further into the sound to learn more about it.

In terms of technical agility, I believe Kz has progressed in all aspects of their BA department. I believe the response is competitive, if not superior in some areas. Let's be more specific.

Sony WM1A - While listening to AS10 Pro with WM1A, the response sounded more expansive and airy, with controlled treble that made it sound balanced, and the bass sounded more distinct and compelling. The midrange felt more forward, while male vocals sounded leaner. However, the mid range does have that clarity and finesse.

FiiO M15S - While listening to AS10 Pro with M15S, the response seemed cleaner and more transparent, but the natural presence I felt with WM1A was lost. The treble sounds sharper and crisper, and the midrange sounds upfront and more expressive. The bass sounded more controlled, a little too controlled, and less apparent in the mix, but it was still discernible.

Tracks​

Conclusion​

So, in the end, it appears that Kz done an excellent job adjusting AS10 Pro in a unique and brighter manner. I am confident that the quality of the drivers and sound has improved; therefore, if you are searching for an all BA set with well controlled bass, forward midrange, and detailed treble, this is the set I recommend.

Review Of The LetShuoer Cadenza 4​

Introduction​

Recently, the brand LetShuoer has been on a roll with continual releases of IEMs and now a dongle dac. The firm was founded in China in 2016 and has been manufacturing IEMs in every category, whether affordable, mid-range, or premium. Their IEMs, such as the S12, EJ07M, and now the Cadenza 12, which is their flagship IEM, have been popular since its introduction. They just launched Cadenza 12's younger sibling, Cadenza 4, which I was fortunate enough to obtain for review reasons, but before we go any further, I'd want to clarify a few points.

Disclaimer​

*Since this unit tour was organised by the lovely people at Letshouer, I am grateful to them. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to these IEMs as “Cadenza 4.”
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the Cadenza 4 based on their performance, even though I will explain how it feels and seems physically and aesthetically.

Specification​

The Cadenza 4 has a multi-driver hybrid configuration with three balanced armatures from Knowles(2) and Sonion(1) and one 10mm berryllium dynamic driver. All drivers use 50 um 3D printed acoustic tubes and an electronic four-way crossover to enable target-specific tuning. The shells are composed of skin-friendly plastic, while the faceplate is constructed of CNC machined aluminum alloy. The shells are ergonomically curved and have a matte white finish, which feels quite safe and comfortable in my ears while still providing a fresh and crisp appearance. This wasn't an issue either because I was able to acquire a suitable fit with smaller eartips. The cable offered is a 392-strand high purity silver plated monocrystalline copper cable that feels amazing and performs well, with two pin connections on one end and an L-shaped modular termination plug on the other. Aside from the cable and IEMs, the kit contains six pairs of eartips in two distinct kinds and three different sizes, three interchangeable plugs (2.5mm, 3.5mm, and 4.4mm), and a sleek and matte-finished carrying bag. According to the technical standards, the impedance is 15 ohms and the sensitivity is 102 decibel. The frequency response ranges from 20Hz to 40kHz.

Sound​

The Cadenza 4 produces a brightish neutral tone with a very revealing and expressive presentation. In terms of technical specifications, I believe these are among the best-sounding options in this price range. When compared to my ideal objective, the IEF Neutral, I believe they are the clearest and most on-point graphs I've ever seen. The response appears light and lean in compared to the likes of the Quintet, Falcon Pro, Da Vinci, and so on, but being one of the finest resolving IEMs, many people will like it for its expressive and vibrant presentation. Although I've always thought DUNU IEMs had a forward and lively sound, these outperform in terms of overall balance, with superb extension on both sides. Even while not every component of the presentation is crisp and well-received, I believe it lacks warmth and authority in terms of note weight and thickness. Let's take a closer look at the sound.

Technical Performance​

When it comes to technical elements, the Cadenza 4 outperforms every other IEM in this price range, including the Quintet and Falcon Pro, as well as IEMs priced more. I believe the Cadenza 4 has more targeted and detail-oriented tuning. Let's go into the specifics.

Sound Impressions ​

Sources​

Sony WM1A - While listening to Cadenza 4 through WM1A, the response seemed more wholesome and full-bodied, making it well-rounded and enjoyable to listen to. The dynamics increased in comparison, with the bass sounding huge and powerful in the sub-bass while losing punch and warmth in the mid-bass. The treble seemed tamed in terms of details and forwardness, allowing the region to sound smooth and silky; the same can be said for the midrange region, but the voices and instruments sounded more weighted and bodied, resulting in a more unified and genuine sound. Tracks like Milet's Anytime Anywhere sounded larger and richer because the notes had more to offer, particularly the voices, which seem appealing and composite.

FiiO M15S - While listening to Cadenza 4 via M15S, the response sounded more sterile and clean with a drop in note weight, but it did not introduce or modify the sound of tuning to become sibilant or shouty. The notes got more illuminating as their differentiation improved. Personally, I noticed that it removed whatever musicality I had from the sound and made it seem dull. The neutral element of the M15S, along with the Cadenza 4's brightish neutral tuning, results in one of the most detailed and clear-sounding responses I've ever heard, without compromising the note's purity. I mean, tunes like Kokoronashi by Majiko were incredibly clear and expressive in a way that made the vocals and instruments seem distinctive and more resolving, but they removed any unified and musical approach to instruments and vocals that used to feel like a recorded live performance.

Tracks​

Conclusion​

To summarize this review, I believe that anyone who like an IEM particularly tuned for the IEF target with a 10-12dB sub bass increase would LOVE these IEMs, as they provide a vivid, sharp, and energetic response while being lean and neutral. Though I'd want to point out that this is not for individuals who prefer fun and warm sounding IEMs, they are welcome to try since the details and clarity will blow your mind for the $250USD price they are being sold for, thus I'll absolutely suggest them.

Review Of The Aful Explorer​

Introduction​

Aful is a reputable firm that has been launching excellent products in all price ranges in recent years. Many audiophiles have acknowledged Aful's hard work and sincere usage of in-house technologies. Since their first IEM, which was marketed as the Performer 5, I have been a fan of theirs. Every product they have released, including the Performer 8, Magic One, and even their first dongle dac, the Snowynight, has been praised and acknowledged by numerous audiophiles, including me. They have now produced the AFUL Explorer, which is a fantastic offering in a more affordable market that I was fortunate to obtain for review. However, before moving on, let me make a few clarifications.

Disclaimer​

Specification​

Two specially balanced armatures and one dynamic 8mm bio-cellulose diaphragm driver are part of the multi-driver hybrid the arrangement found in the Explorer, which is linked to an internal RLC crossover. These are equipped with their 3D printed acoustic tubing, which features a special resonator technology that they have used to all of their IEM releases thus far, with results that have shown to be authentic. In order to aid in a better fit, the shells have longer nozzles and a smaller body. In my opinion, because of the ergonomic shape and small form factor, tip rolling shouldn't cause any problems with fit or comfort because I was able to achieve the right seal and comfort, especially when using these for extended periods of time. The 200 core dual strand high purity copper silver plated cable that comes with the IEM includes a two pin connection on one end and a 3.5mm straight termination connector on the other; however, you can choose to purchase a 4.4mm termination option instead. For the price, the cable is truly excellent; it is flexible and performs well. Three sets of eartips in various sizes and a carrying circular case finish out the accessories. Regarding the technical details, the sensitivity is 108dB and the impedance is 26 Ohms.The range of the frequency response is 10Hz to 30kHz.

Sound​

Although there are many IEMs in this price range or less that follow the same quality of tuning, the richness and refinement that the Explorer offers is impressive while being very tonally inclined. The Explorer has a very cohesive and warmish sound that leans towards a balanced sound with rich tonality and decent technicalities for the price these are being offered at. Anyone searching for an IEM that sounds fatigue-free will find the sound to be particularly endearing or favorable, especially given the IEM's compact and snug form factor. IEMs with similar energetic high frequencies as the Explorer, but executed far better, don't have the same luscious and deep tone. IEMs like the P1 Max II, EM6L, etc. sound balanced, engaging, and satisfying enough. Even while I recognize that the relative lack of extension and air prevents an open, airy sound, I still think it's worth the money to have a balanced, tuned IEM that sounds vibrant and active without coming off as offensive in any manner. To learn more about the sound, let's explore it more thoroughly.

Sony WM1A - When listening to the Explorer with WM1A, the response seemed considerably roomier, with the upper treble being more noticeable and the lower treble being more subdued, allowing for a fuller and more airy response. The male vocals were too thick, but the mid range sounded the same with muted lower treble and richer notes that maintained clarity and vibrancy. On songs like "Over My Head" by The Fray, the vocals were more thick and lush, preventing them from sounding more energetic and prominent. Instead, they were enveloped by the instruments as they scaled higher. Despite the fact that the instruments sounded fantastic, the song was pleasant to listen to altogether.

FiiO M15S - Incredibly, the tone didn't seem any different when listening to the Explorer with M15S; instead, the richness and thickness felt a little lacking, which resulted in a lack of warmth. The response sounded much more transparent and leaner with more forwardness in the lower treble, bringing more details and clarity. This kind of reaction enhanced the bass texture and details' differentiation from the notes. The presentation as a whole sounded lively and conclusive. Ai Higuchiu's song "Akuma no Ko" has an incredibly rich, airy, and clear tone. The bottom notes were highly defined and controlled, and the instruments sounded crisper and sharper than the vocals, which presented themselves in a very open and expressive manner.

Review Of The Celest Relentless ​

Introduction​

Disclaimer​

Specification​

Sound​

I discovered when listening to the Relentless that the tuning is in the proper V-shape and that many people would love it because of how distinct and detailed it sounds. Listening to them, I can tell that Celest has struck gold. IEMs in this price bracket sound either highly revealing, adding some noise to the mix that first seems detailed and fascinating but might get harsh and piercing after lengthy listening. Out of all the bright and detailed sounding IEMs in this price range, I think that this well-tuned model with decent control over offensive characteristics being introduced and friendly response it creates is what most people would like. In terms of the treble It is really well-executed with excellent details; the midrange is clear and prominent, and the bass has a powerful, weighty presentation that many people will love. Even if these particular features seem wonderful, I believe that the relentless may not be the right fit if clarity or resolution come to mind. Let's investigate the sound more thoroughly and learn more about it.

Sony WM1A - I believe the notes in the high frequencies got more rounded and much more enjoyable to listen to without sacrificing any extension or air while listening to the Relentless with the WM1A. I also found that the response sounded much broader and deeper to add more heft and warmth in the bottom notes. Overall, I think the response is smoother and sounds better than a v-shape.

FiiO M15S - The response from the Relentless with M15S sounded cleaner and crisper than from any other source I tried. The treble became less forward-provoking and the bass became more regulated, resulting in an improvement in the clarity of details and resolution. Though it is not a particularly perceptible improvement, the mid range felt significantly resolved, with singers and instruments sounding stronger in clarity and precision. It sounds really lively and V-shaped, with a more structured bass and crisp mids and treble, but it also has a feeling of clarity and detail.

Sony WM1A - When listening to the Prado with WM1A, the treble response was more expansive and airy, and the bass notes had greater dynamics and sounded fuller while maintaining a huge, rich, and well-rounded sound. The overall presentation sounded well-balanced and calming, although the mid range—especially the upper mid range—sounded emphasized. Vocals on songs like Anly's Sukinishinayo seemed full-bodied, open, and filled at the same time. Despite the bass notes feeling too thick and deep to provide clarity to the mix, the instruments had a more dense response and were still quite calming to listen to.

FiiO M15S - The Prado with M15S produced a response that was crisp and clean to listen to. The presentation was still melodic, but it was also more detailed and distinct, particularly in the higher frequencies. The lower treble also seemed livelier and crisper, even if the higher treble sounded almost the same. The vocalists and instruments sound more energetic in the upper mid range. Conversely, the bass had a more subdued tone and a punchier, rumblier response. Tracks like Miliyoh's Kono Yumega Samerumade had vocals that were passionate and personal, but the music was crisp and snappy, deep and powerful but under control.

Review Of The Canpur CP622B​

Introduction​

Canpur is an electo-acoustic production firm that specializes in in-ear monitors. The brand was founded in 2019 in the Netherlands. This firm was founded by Mr. Hans JAPM Witjes, a professional band drummer since the 1980s with approximately 30 years of expertise in live performances and sound tuning. One of the most important factors that sparked this entire process was the development of low-cost equipment for professional musicians, vocalists, and sound engineers. The name Canpur is derived from "CAN PURE," which represents "resoration, purity, and auditory pleasure." They have a vast line up of IEMs ranging from 320 dollars to 4900 dollars, but they have only lately gained attention for their flagship product, the Canpur 622B. I was fortunate enough to get my hands on them for review, but first I'd want to clarify a few facts.

Disclaimer​

Specification​

The 622B has a 10-driver arrangement that is a tri-brid setup consisting of 2 electrostats, 6 balanced armatures, and 2 bone conduction drivers paired with a 5-way crossover and employs in-house technology known as micro-inverter tube design. The shells are on the larger side and very nicely crafted. I believe the faceplate provides gradience with a rich and lovely appearance. The entire shell seems and feels quality and professional, however the larger size may be an issue for those with small ears, but with the correct eartips, the fit is doable. Personally, the fit and comfort were satisfactory, with the exception that I had to replace eartips to Divinus velvet eartips to achieve a decent seal. The cable included with these IEMs is from Electech, a firm that specializes in premium and luxury cables, and I believe it is a pretty decent cable with nice thickness, flexibility, and appearances that complement the IEMs. The cable is a 7N high purity single crystal copper cable with a two-pin connector on one end and a 4.4mm straight termination plug on the other. The additional accessories include a choice of eartips, a cleaning cloth, a cleaning brush, and a luxury leather casing that feels and looks authentic. According to the technical parameters, the impedance is 8.9 Ohms and the sensitivity is 103.8dB. The frequency response ranges from 20Hz to 70kHz.

Review Of The TangZu X HBB Xuan NV​

Introduction​

It has been a while since I reviewed any new TangZu products; the ones I was able to check out were the ones that were recommended at the time of its introduction, such as TangZu Wan'er, Shimin Li Encounter, FUDU Verse, and so on, with FUDU Verse and NehZa being the most recent. The firm was founded not long ago, but it has only just gained traction. Originally known as T-Force, the Chinese company was later renamed TangZu. The company launched the XUAN WU GATE shortly after NehZa, which I was unable to review; however, they just released another IEM known as the Xuan NV, which I was lucky enough to obtain for review. Before starting, I would want to clarify a few things.

Disclaimer​

Specification​

Sound​

I'll come right out and say that the Xuan is the most cohesive and resolved IEM among its rivals, including the SIMGOT EA500 series, the new Kefine Delci, and even the EPZ Q5. In comparison, when it comes to the Xuan, the response throughout the region is the most fluid and transparent. Although I find that the response is not as forthright as the other, it raises questions about its clarity and detail understanding, which may not be its strong strength. The balance of all regions helps bring everything to the table, making it sufficiently comprehensive and illuminating. The intensity of the notes in the upper frequencies prevents fatigue or harshness in the mix, so I was able to listen to these for a whole day without having to remove them once. The strangest thing is that I slept while listening, which may be the magic of dynamic drivers. The bass is done very cleanly, and it does not provide a lively engaging response like the Delci, nor does it produce a bright neutral sound in the mix like the EA500LM, but rather a warm-neutral presentation that maintains the whole response sounding extremely safe, coherent, and silky. Let's go further into the sound and learn more about it.

Review Of The KZ ZS10 PRO II​

Introduction​

It's been a long since I've tried a KZ IEM; if I recall well, it was their latest rendition of the full-range planar IEM, the KZ PR3, which I really liked. When it comes to KZ, it has a particular place in my heart because their IEMs were the first ones I explored and stepped on in the audiophile world; I had no idea at the time that sound could be this fantastic, and I desired to have the best sounding IEM. Now that I know there is nothing like that, it is too late for me, but for most people, including myself, Kz serves as a bridge between the average consumers and audiophiles. Not that I say they're the best, but they did their job as a specialised electro-acoustics manufacturer and one of the oldest, offering their products at a price that anyone can enjoy excellent sound. I believe KZ deserves some space and love regardless of what they've done in the past, though I do wish they would stop claiming things that give an ignorant vibe. Returning to their offerings, one of their most popular IEMs, hailed by many when it was first introduced, was the ZS10 Pro, which I also possessed for a full two years until they died. They just introduced a new version, the ZS10 PRO 2, after the ZS10 PRO X. Fortunately, I was able to obtain a pair of ZS10 PRO 2 for review, but before we go any further, I'd like to clarify a few things.

Disclaimer​

Specification​

The ZS10 PRO II features a multi-hybrid driver configuration made up of two dual 31736 balanced armatures and a single dynamic driver. All of their five drivers are custom-made by KZ and are coupled via a 4-switch tuning board, allowing for four alternative tuning options. The shells are constructed of high-grade plastic, which KZ currently uses for all of its IEMs, and the faceplate is metal with an open-back design. To be honest, the IEM looks cooler than its predecessors, albeit the addition of tuning switches makes me a bit concerned about the design. The comfort is excellent since the IEM adheres to their classic yet extremely ergonomic design, and neither the fit nor the comfort of any Eartips I tried were compromised. The cable included with the IEM is the standard two-wire silver cord that KZ provides with their more priced IEMs. The cable features QDC connections on one end and an L-shaped 3.5mm termination plug on the other. Aside from the wire, the accessories include three pairs of eartips in varying sizes, a pair of foam tips and a tuning pin. According to the technical parameters, the impedance ranges from 25 to 28 Ohms, and the sensitivity is 108 dB. The frequency response ranges from 20Hz to 40kHz.

Sound​

While reviewing the ZS10 Pro II, I noticed that the factory set tuning, with all switches, toggled upwards, made it sound more like a bright V-shape tuning with a highly focused upper mid-range and entire treble and equally emphasised bass, but when it comes to the mid-region, this time around they brought a more energetic response in the upper mid-range to not drown the vocals. When it comes to competing with its rivals like Forteza, Sonus, Jojo, etc, I believe it is well-positioned to appeal to consumers who want the typical KZ sound but with an upgraded and cleaner sound, which is far too clean in my opinion. Let's go further into the sound to learn more about it.

Tuning Switches​

There are four tuning switches that vary the tune differently each time it is toggled or played with; nevertheless, in my view, it functions more like a bass level switch, as the more switches you toggle upwards, the more bass appears in the mix. During my tests, I discovered that the more I switched down, the more the higher frequencies stood out in the mix. In terms of personal taste or preferences, I prefer a neutral with a sub-bass boost, which I was able to achieve with a combination of UUDD and UDDD. Still, surprisingly, I preferred the UUUU combination because it made it sound more tonally pleasing rather than lean or shouty in my opinion. As a result, tuning switches are completely pointless to me unless I want a dark-sounding track to sound clear and revealing.

Tracks​

Conclusion​

To summarize this review, I believe Kz continues to serve as a bridge for consumers and novice audiophiles to learn more about their tastes and what they enjoy. ZS10 Pro II is an appealing product for a newcomer looking for a conventional bassy sound with great-sounding details at a reasonable price. The ZS10 series has been and will continue to be a fun and engaging IEM, with each new release enhancing details, clarity, and tonal presentation. So I suggest this IEM for individuals looking to dig deeper into the audiophile realm or for an IEM that sounds engaging, vibrant, and exciting.

IEMs​

When I listened to this coupling, the response seemed nicely spread out and forward in the mid-range, particularly the vocals. The presentation sounded less expansive, but the note expression was more textured and detailed, with a bright contrast that allowed for a far more resolved response, resulting in a more analytical approach to the mix. Whether I'm listening to Kool-Aid by Bring Me The Horizon or Miliyah's Kono Yumega Samerumade, there's a lot going on that sounds really revealing and vivid without being confusing or overlapping. Surprisingly, the entire presentation sounds entertaining and intriguing.

FlipEars Aurora

Aurora establishes itself in this market as one of the greatest musical and warm-sounding IEMs, providing a detailed but calming response that even my Prestige LTD cannot match. To be more specific, the Aurora has a warm-neutral sounding response that enables for a cohesive and effortless sound regardless of the music I choose. When it comes to the Prestige LTD, I believe the clarity, realism, and tonal correctness are the greatest. Aurora bends that will and produce a profound sense of natural sound that sounds precise and clear enough to provide harmony into the mix, which is better done on these IEMs. Because of the way the treble is adjusted, the response does not lean clinical or sterile in the upper harmonics. The midrange produces a spacious sound, and one will fall in love with the note’s depth, weight, and precision. The bass's impact hits you so hard that it leaves you in wonder due to its rapid striking and natural decay of the notes, which is backed by two subwoofers, resulting in a highly robust production of bass heaviness and presence without sacrificing clarity across the spectrum.

When I listened to this pairing, I saw that the response, which was energetic, thrilling, and engaging, enhanced in terms of what Aurora does well. Satellite by Valentino Khan is a great example of this, with its shimmering treble, revealing mid-range, and firing subwoofers packed with strong and impactful thumps and punches all sounding more textured and detailed, with better control over attack and decay of the notes allowing more details to conspire and more room for them to sound full and rich. However, in tracks such as Kohana Lam's A Few Sentimental, the vocals are unexpectedly sweet and tranquil, with a more upfront approach that provides a deeper and richer experience.

Thor Mjolnir MKII

Mjolnir is a very bassy set that has a lot of sub-bass emphasis. The treble and upper mid-range are also very forward in the mix. The upper treble has great extension as well. The bass is very punchy and boomy while acting fast. Mjolnir is a great V-shape-sounding IEM with a different approach to explosive bass that has better technicalities, especially in this price range. The stage is great with a nice surrounding stage and depth where the separation of each element sounds distant enough to procure space to breathe and distinguish themselves. The attack and decay of the driver capability are really quick and perform great. The vocals may feel lean and sparkly, but the warmth or the fuller experience is something that these lack. The bass response does vary from source to source whether I listen to a warm source or a neutral one, the bass becomes either overwhelming authoritative or both.

Conclusion​

To conclude this evaluation, I can happily state that the M15i has the same sound but has been enhanced to the point where the noise, clarity, and, most importantly, cohesion sound make it highly appealing to people seeking the finest clear and transparent sounding dongle available. After listening to the M15i, I felt the same sense of astonishment and exhilaration that I had when I first heard the M15. Congratulations to Questlye for incorporating such a tweak into this generation of the M15. So all in all. I heartily recommend the Questlye M15i, especially at this price range, however I'd want to advise existing M15 customers to test it out before going through the process.

Conclusion​

To summarize this review, The Flipears did an outstanding job of tuning such an aesthetically pleasing IEM with such a driver arrangement. Simply said, I cannot express how remarkable and musically sounding they are, with tone and technical abilities comparable to their competitors. I believe that Aurora's cohesive and powerful sound is just unparalleled since it maintains a unique position in the market and I find it very compelling, thus I wholeheartedly suggest these.
