Kiwi Ears Aether 4★★★★
Driver Configuration : 15.3mm Large Planar
MSRP : $169.99

▓▒░ SOUND-SIGNATURE ░▒▓
To put it simple. It has a warm, mild V-shaped tuning.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- It has a tasteful amount of bass-shelf. Like most planar drivers, the bass is fast and detailed, but the overall impact leans towards the softer side.

- The lowest range of bass frequencies is often heard rather than felt. With its quick attack and decay, the subwoofer-like rumble or the vibration feel from bass heavy music is lacking the final touch of sustain and pressure. The sub-bass just don't tingle your ears like a proper dynamic-driver would do.

- Thankfully, the mid-bass elements have greater substance which makes up for it. It feels thicker and fuller. The tempo is slightly slower with a hint looseness edge. The notes offer a slightly heavier, more percussive quality to them while providing warmth and fullness that it needs. Kick-drums and tombs have this soft yet deep "thud". The drum strike has good depth to the slam, while the bass guitar has a clear and defined tone. Ghetto bass replay has a decent bounce while bass-drop and bass distortion elements maintain a decent clarity.

- It is not the tightest nor the cleanest bassline. There's a noticeable bass-bleed onto the lower-midrange which can makes vocal sounds fatter. On certain pairing, there is a hint of bass bloat, but it is not overwhelming.

- Despite the critical take, this has got to be one the very few planar sets that can come close to the bass performance of a well-implemented dynamic driver.

▓▒░ MID-RANGE /VOCAL ░▒▓
- Vocal intimacy isn’t its primary focus, as vocals are slightly pushed back in the mix. However, they never sound too thin, dry, or overly recessed.

- The overspilled mid/upper bass presence somewhat impacts its clarity and transparency. Even so, it manages to capture subtle nuances and textures reasonably well. Mid-range separation is average at best, with vocals and instruments blending together when the mix gets busy.

- The added warmth from the lows ensures that vocals and instruments sound smooth, lush, rich, and pleasing to the ear.

- The dynamic range is generally good, though not outstanding. The elements of rise and fall in volumes is well captured, offering vocal and instruments a good sense of expressions and emotions while not playing it too safe. Piano taps, violin strums, guitar plucks, and flute whistles all have a more rounded attack, yet maintain a natural note weight, sustain, and extension that make them distinct yet soothing to listen to.

- However it is not all perfect. At times, chesty male vocals (baritones), cellos, brass instrument, organ that lives on the lower region of the mid-range sound slightly distant. While high-pitch female vocals may come across a tad too husky. The higher range of vocals just missing a certain breathy quality that can make them feel ethereal.

- Depending on the track, there may be a hint of vocal grain at the tail end of the voice.

- If correctness or less coloured mid-range is what you're after, this is may not be the right choice. However, vocal enthusiasts might still find it enjoyable, as it doesn’t have any unpleasant tonal qualities.

▓▒░ TREBLE/HIGHS ░▒▓
- The warm hues coming from the lows, makes the treble sounds darker than the measurements suggest. But it is not too dark and dingy. The lower to mid treble region do still carry enough brilliance to avoid sounding dull. Air extension is more subdue, which nerfs some of that airiness and openness to stage.

- Though it doesn't have the most well-filled out treble, the response remains fairly smooth, steering away from any sort of peaks, harshness, sibilance, or shout. And from a planar driver standpoint, there is almost zero sharpness or metallic sheen is heard which is impressive.

- The treble detail isn’t the crispiest or most pronounced, but the smoothness allows the highs to come through naturally without feeling forced, making it more comfortable for treble-sensitive listeners.

- Cymbals and hi-hats, though has less prominence, showcase a remarkable timbral accuracy, capturing their delicate high-end shimmer. Similarly, the drum snares maintain a crisp yet smooth, high-pitched rattle. The glockenspiel retains its bell-like dings. Synthetic noise like electronic zings, rings, buzzes, as well as electric guitars, come through with a more rounded edge and acceptable bite.

- Having tuned not to impress treble-heads, there is one minor issue: On some recordings, there's a hint of subtle grains in the treble, which may or may not be noticeable. Aside from that, there is no deal breaking issues.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The HEAD-STAGE of the Aether isn’t particularly wide, and the headroom is not very tall, but it offers a decent sense of depth. The background isn’t particularly dark either.

- IMAGING AND SPATIAL CUES seem to be one of its weaker points. While the image is large and accurate, it doesn’t stand out with vivid clarity. It feels a bit blurry compared to some of its competitors.

- INSTRUMENT SEPARATION is good, though not exceptional. Due to the relatively small stage dimensions, the space between elements isn’t the most generous. However, its speed ensures great consistency in maintaining the boundaries of each sound.

- In the grand scheme of things, the DETAIL-HANDLING is above average. But in planar game, it is not the absolute best.

- As mentioned, the DYNAMIC RANGE is near lifelike, making your music feel alive and never boring.

- When it comes to TONE AND TIMBRE, the Aether is one of the few planars that doesn’t exhibit the typical “planar timbre.” There’s no metallic sheen or sharpness in the upper-mids or lower treble. The attack is softer, but the natural decay and sustain make up for it, resulting in a sound that’s both fast, smooth, and warm.

- Thanks to its warm, smooth nature, you can still crank up the VOLUME higher than usual, at least with my current setup and test tracks.

- This 15.3MM PLANAR DRIVER is truly capable, and I believe there’s still room for further improvement.

✧ ════ •POTENTIAL SYNERGY/TWEAKS• ════ ✧
EARTIPS: The stock eartips are decent, but my preferred choice is the SPINFIT CP100 (Non-Plus). Not only are they more comfortable, but they also enhance vocal intimacy. The only downside is that they can cause bass bloat. In such cases, switching to wider-bore tips is a good solution.
Options like Moondrop Spring Tips, Corier Alloy, or Divinus wide bore eartips work well for this.

DAC/AMP: Fortunately, it’s not difficult to drive and performs well even with the Kiwi Allegro Pro. Personally, I find it scales better with a higher-quality amp that has a neutral, less warm coloration. It’s best to avoid pairing it with anything that emphasizes mid-bass.

✧ ════ •BUILD/ PACKAGING/COMFORT• ════ ✧
- The shell is solidly built, lightweight, and doesn’t feel cheap, featuring a beautiful purple glittering faceplate. However, it is on the bulkier side, so those with smaller ears might need to do tip-rolling for optimal comfort.

- The unboxing experience is fairly standard. It comes with a small carry case, a few sets of eartips, and a 3.5mm SE cable. And surprisingly, there's no 4.4mm balanced plug option available in 2025!

QUICK HEAD-2-HEAD
vs Kiwi Ears Airoso/Stock 3.5SE Cable/Spinfit CP100 (M)
- The AIROSO has a neutral balance tuning with a bright tilt, while the AETHER features a warmer, V-shaped sound.

- The bass on the AIROSO is quicker, deeper, punchier, and more visceral overall. And not to mention, AIROSO’s bass control is a step above. In contrast, the AETHER has a warmer, boomier, and loosened response. Its sounds is fatter, bigger, with a slightly slower attack and decay. When it comes to bass detailing, AETHER takes the lead.

- The AIROSO is more mid-centric of the two, with vocals taking up a larger space on the stage. The separation between vocals and background elements is clearer, up to a certain threshold. Meanwhile, the AETHER has a softer focus on vocal reproduction.

- The vocals and instruments on the AETHER sound more natural and lifelike, with greater liveliness and expressiveness. It does a better job of highlighting subtle nuances and textures, including reverb and overtones. However, the AIROSO’S vocals are cleaner and clearer, without the occasional graininess that can sometimes appear on the AETHER.

- The AIROSO has superior treble extension, giving it a more airy and open sound. Overall, it sounds clearer, and cleaner compared to the AETHER.

- The AIROSO has a wider, more open soundstage and darker background while the AETHER offers a slight edge in perceived depth.

- The AIROSO has sharper imaging and spatial cues, while the AETHER presents a larger image.

- On simpler tracks, the AIROSO can separate its elements more clearly than the Aether. However, on more complex tracks, like rock, metal, or orchestral music, the AETHER'S planar speed allows it to maintain more consistent separation while present additional layers in the music.

- The AETHER is more resolving, with micro-details presented in more layers.

- Not only is the AETHER more dynamic, but its tone and timbre also sound more natural. From end to end the notes feels more complete and better defined. Despite its softer attack, the sustain and decay are more accurate. To the contrary, on the AIROSO, some notes may fade a bit too quickly.

- The AIROSO’S has a smaller shell. And cheaper to own as well.

- Both are easy to drive. Just that the AETHER requires a smidge more power.

- Both of have nigh identical packing and accessories.

“ To my ears the Airoso has better tuning. It sounds more balance and has greater extension on both ends. But it is the Aether that will capture the hearts of many audiophiles. Its more dynamic, its more technical and the overall timbre just sounds slightly more natural.”
.
◤FINAL THOUGHTS◢
Another homerun from Kiwi Ears. I love seeing them improvise their product at more affordable prices. With the Aehter, it has made "Planar War" more competitive than it has ever been. Other than the 7hz Timeless II, the Aether might just be my 2nd favourite planar to date. But do bear in mind, as good as people claimed it to be, it is not flawless.

EXTRA PHOTOS

So in direct comparison to Timeless II, what exactly makes them better than Aether for you, aside from modular cable and swappable nozzles?

@Nokiaman87

Hye @Nokiaman87

This is based on my 30mins demo session at my local store (with Gold Flower nozzle on)/ CP100 tips.
- Tuning : it sounds more balance. Whereas the Aether is on the warmer,bassy side.
- Bassline : I find the Timeless 2 to bass to sound more engaging yet has better overall control.
- Mid-range/Vocals : The Timeless seems to have greater vocal intimacy. Vocal just sound more correct to my ears.
- Treble : Ever so slightly brighter which suits my preference.
- Packaging/Price : Yes it is more expensive but you do get alot more stuff for your money. And theres no need for me to spend some extra cash on top for a 4.4 BAL plug.

- Caveat : probably the shell shape, some claimed to have issue with fit which is a big no-no to some. No point if it sounds go but can't fit your ears well.

Still, I do not think the Timeless 2 will replace the Aether or vice versa. They went for a more different approach catered for different people.

I hope that helps.

DestinoAzell

@DestinoAzell thanks for the clarification, more or less what I thought of those two myself. Still, looking at the FR graphs, sub-bass and lower mids of Timeless II, especially with the dome nozzles, do seem a tad warmer/more pronounced. What about the soundstage, other reviews say Aether has a bit more depth and height than other ~$200 planars. Would make them more interesting for gaming, if it's true.

@EvelynZ

Kiwi Ears Airoso 4½★★★★
Driver Configuration : 1DD + 4BA Hybrid
MSRP : $129.99

▓▒░ SOUND-SIGNATURE ░▒▓
It has a neutral, bright-leaning sound with a sub-bass boost. The mid-range and vocals are more forward in the tri-frequency range, while both the bass and treble have ample extension at both ends of the spectrum, resulting in a well-balanced sound.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- The low-end is emphasized in a way that makes it sound fast, tight, and precise. While this level of bass may not satisfy hardcore bass enthusiasts, it is more than sufficient for delivering a well-balanced bassline.

- The sub-bass has a slightly more prominent presence with respectable low-end extension and texture. However, its short sustain and tight attack mean that rumbling, growling, or booming sensations are more controlled and focused. Those seeking a high-resonating sub-bass might disappoint.

- The mid/upper bass is almost identical in character, though slightly less present. The attack still maintains a decent density and impact. Its steady presence adds warmth and body to vocals and instruments, with kick drums and toms offering a more noticeable thud. While the drum strikes may not have the hardest slam and the bass guitar could use with more grunt, ghetto bass lacks the usual bounce. Additionally, bass drops and distortion elements aren’t as well-defined.

- While the bass may not be the last word in definition, considering its tuning and price point, the bass performance is no slouch. More importantly, it remains enjoyable to listen to.

▓▒░ MID-RANGE /VOCAL ░▒▓
- The cohesive bassline, combined with its well-articulated treble response allows for a balanced, smooth, clear, yet natural mid-range and vocal rendition.

- As a result, it make its one of the better mid/vocal centric set among its peers. Vocals and instruments (guitar, piano, violin, strings, flute) will sound more to the fore and often given a greater focus in the mix.

- Tonally, they have a good sense of note-weight behind them with subtle texturing and adequate range of dynamics. Both male and female performs just as rewarding on stage. And they're well separated from the background elements across various tracks.

- Moreover, there are no issues with graininess, sharpness, shoutiness, or sibilance is heard. It sounded clean and clear.

- While it may not capture every nuance or expression of vocals as effectively as higher-end models, it still conveys emotion and offers a good level of micro-detail.

- In fact, it strikes a nice balance between clarity and euphony, delivering a solid mid-range performance nonetheless.

▓▒░ TREBLE/HIGHS ░▒▓
- The treble performance is the highlight of this set. It leans slightly toward the brighter side of the spectrum, but it is nicely executed. The sound is airy and open, without being overly bright. It rises and dips precisely where it needed, avoiding any unwanted resonance that could spoils its response. Unlike some other bright-leaning sets, it doesn't mask the lower harmonics.

- As with many budget sets, the balance-armature’s treble response can sometimes show graininess, haziness, sharpness, or harshness when pushed to the limit. Even the KE4, its predecessor, struggles with this, particularly at higher volumes or on poorly recorded tracks. Fortunately, this isn’t an issue with the Airoso. Its treble is more refined and forgiving, delivering a smoother, cleaner, clearer sound.

- Constant hi-hats, cymbals, and drum brushes sound rather pleasant. Despite their prominent presence, the trailing shimmer or sizzle of notes doesn’t come across being too metallic or sharp. The snare drums have a nice crispy high-pitched rattling sound. As for synthetic noises like electronic zings, rings, buzzes, and electric guitar, they stand out with just the right amount of bite.

- While the treble detailing isn’t the absolute best, it’s more than adequate for critical listening.
It’s worth noting that with brighter pairings, the treble brilliance may cause some fatigue, so treble-sensitive listeners should be aware. However, for most people, this won’t be a deal breaker.

- The treble response is surprisingly well-tuned. For just $129 bucks, that’s an impressive feat.

✧ ════ •TECHNICAL PERFORMANCE/ASPECT• ════ ✧

- The STAGE width feels wide. However, the perceived front-to-back layering is not much, and the vertical headroom feels somewhat limited. The mid-range/vocals seem to occupy the majority central space of the stage, surrounded by bass and treble instruments.

- IMAGING PROWESS is generally accurate, though the image definition isn’t the most vivid I’ve heard. That said, the localization and positioning of sounds between channels are solidly presented.

- The background is darker than average, enhancing the SEPARATION LEVEL. While the space between instruments isn’t overly generous, it maintains good consistency in keeping the sound boundaries distinct, preventing from further congestion or compression issue. Though, on a more demanding tracks like progressive rock or symphonic metal it will starts to struggle a little thanks to its somewhat 2D-stage dimension. Still, given the tier it competes, I have no complaints.

- DETAIL RETRIEVAL isn’t its strongest suit. While macro-detail is solid, it falls short ever so slightly when capturing finer micro-nuances present in both vocals and instruments. This level of detail handling is typical for this price-range.

- As for DYNAMICS, the range isn’t extremely expansive but is wide enough to handle most genres well. The contrast between loud and soft elements in vocal and instrument playback tends to be more subdued.

- The overall TONE AND TIMBRE sound mostly natural to my ears, with no moments where it feels off. It managed to sound fast and smooth yet natural at the same time which is quite pleasant. The attack isn’t the sharpest, but it’s not overly blunt. The decay is relatively fast but remains precise. The notes maintain good weight, although a greater sense of reverb or overtones would enhance the sound, as it feels lacking in certain instances.

✧ ════ •POTENTIAL SYNERGY TWEAKS• ════ ✧
- EARTIPS: The stock ear-tips works just fine but if I had better listen experience when using the SPINFIT CP100 (Non-Plus). These enhance vocal clarity while adding more low-end body and reducing some of the top-end sizzle.

- DAC/AMP: Given its bright-leaning treble, it's best to avoid pairing it with a brighter source, as this can throw off the treble balance and potentially lead to fatigue over time. For example, it pairs better with the warmer, less aggressive Tanchjim LUNA than with something like the Tanchjim SPACE, which has a more energetic treble.

✧ ════ •BUILD/ PACKAGING/COMFORT• ════ ✧

~~~Kiwi Ears Official Photos~~~
- As with most Kiwi Ears products, the build is solid but not particularly remarkable. The shell feels sturdy, though not overly premium to the touch. More importantly, the shell isn’t too large and lacks any sharp edges that might cause discomfort.

- The unboxing experience is fairly standard for Kiwi Ears—nothing too exciting—but it does include a small, practical carrying case and six sets of silicone eartips, ranging from small to wide bore with three different sizes each. My only complaint is that, at $129, they could have included a more substantial cable with a 4.4mm balanced termination plug.

QUICK HEAD-2-HEAD
vs Kiwi Ears Aether/Stock 3.5SE Cable/Spinfit CP100 (M)
- The AIROSO has a neutral balance tuning with a bright tilt, while the AETHER features a warmer, V-shaped sound.

- The bass on the AIROSO is quicker, deeper, punchier, and more visceral overall. And not to mention, AIROSO’s bass control is a step above. In contrast, the AETHER has a warmer, boomier, and loosened response. Its sounds is fatter, bigger, with a slightly slower attack and decay. When it comes to bass detailing, AETHER takes the lead.

- The AIROSO is more mid-centric of the two, with vocals taking up a larger space on the stage. The separation between vocals and background elements is clearer, up to a certain threshold. Meanwhile, the AETHER has a softer focus on vocal reproduction.

- The vocals and instruments on the AETHER sound more natural and lifelike, with greater liveliness and expressiveness. It does a better job of highlighting subtle nuances and textures, including reverb and overtones. However, the AIROSO’S vocals are cleaner and clearer, without the occasional graininess that can sometimes appear on the AETHER.

- The AIROSO has superior treble extension, giving it a more airy and open sound. Overall, it sounds clearer, and cleaner compared to the AETHER.

- The AIROSO has a wider, more open soundstage and darker background while the AETHER offers a slight edge in perceived depth.

- The AIROSO has sharper imaging and spatial cues, while the AETHER presents a larger image.

- On simpler tracks, the AIROSO can separate its elements more clearly than the Aether. However, on more complex tracks, like rock, metal, or orchestral music, the AETHER'S planar speed allows it to maintain more consistent separation while present additional layers in the music.

“ To my ears the Airoso has better tuning. It sounds more balance and has greater extension on both ends. But it is the Aether that will capture the hearts of many audiophiles. Its more dynamic, its more technical and the overall timbre just sounds slightly more natural.”

◤FINAL THOUGHTS◢
This is what the KE-4 should have been. To my ears the Airoso is much better tuned yet sounds more refine at a fraction of the price. It has become one of my favourite Kiwi Ears after the Quintet. It has every bits of everything to keep you listening to it. For just $129, I’d recommend this set in a heartbeat, especially if you're cross-shopping for a well-balance set at this price-point.

BQEYZ FROST 3½★★★★

-SOUND IMPRESSIONS-

▓▒░ SOUND-SIGNATURE ░▒▓
The Frost provides a slightly warm, neutral tuning that delivers a laid-back and smooth sound. The emphasis on the mid-bass subtly boosts the low-end presence, while the top end offers sufficient extension for a more balanced presentation. The mid-range and vocals are far from recessed. The colouration from both ends gives the vocals a smooth yet natural quality in their delivery.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- The bassline is tuned intentionally with a mid-bass-biased in mind.

- On sub-bass heavy tracks, the sub-bass roll-off is noticeable but not severely lacking. While rumble, drone, and hum sensation are present, they may not deliver the strong, sustained vibration or impactful boom one might expect.

- Having a greater mid-bass presence concentrated in the lows, the sound is fuller, thicker, and somewhat slower compared to the sub-bass. However, in terms of attack, it’s not the most expansive, lacking some depth on transient. Regardless, it still delivers a decent kick and punch to keep listeners engaged. The drum strikes have ample slam, and the bass guitar focused more on fundamental presence. Thankfully kick-drums and tombs offer a more satisfying thud. Bass drop is kept clean and smooth while ghetto bass replay has decent bounciness and dispersion to them. Bass distortion elements however could use with better definition.

- The mid-bass spill, coupled with its somewhat sluggish nature, can sometimes cause a bloated sensation on faster bass tracks, making it less ideal for j-pop and ACG music.

- Overall, the bass performance is just average. While the dynamics and layering could be improved, it’s perfectly suitable for a more laid-back, relaxed listening experience.

▓▒░ MID-RANGE /VOCAL ░▒▓
- The vocals are more forward, though not overly intimate.

- The added warmth from the lows contributes to a richer, fuller reproduction of both vocals and instruments. Male and female vocals are equally well-performed, without one overpowering the other in duets. While vocal and instrument separation is seamless, it’s not quite at the highest level.

- However, it’s not without its flaws. There’s a slight lack of vocal transparency. While the vocal fundamentals are clearly laid out, subtle details in vocal phrasing, such as breath sounds and vocal fry, are less prominent. The smoother approach tends to downplay these nuances in vocal texture.

- Additionally, there’s a faint trace of micro-grain in the vocal transients, which is less than ideal.

- Another minor drawback is the lack of emotional depth in the vocal expression. The natural rise and fall in vocal intonation feels somewhat suppressed, and subtle overtones or reverb at the trailing end of the voice are absent. These same traits carry over to instruments like guitar, piano, violin, strings, and flute, causing each note to lose a bit of its expressive character.

- On the plus side, vocals are always smooth and controlled, especially when handling high-pitched, shouty, or screechy voices. Despite these minor issues, the vocals and instruments never come across to sound unnatural, which is a positive sign.

▓▒░ TREBLE/HIGHS ░▒▓
- The treble takes a more neutral, balanced approach, avoiding extremes of being too dark or too bright. It extends reasonably well, reaching into the mid-treble region, with air extension that’s adequate but not overly expansive. While it doesn't offer the openness and airiness often found in a brighter set, it provides just enough treble brilliance to cut through it's bassline and allow vocals and higher harmonic instruments to stand out.

- There are no unwanted resonances, such as harsh peaks or glare, and sibilance is well-controlled.

- Cymbals and hi-hats have a more backseat presence on stage. Though, have natural decay, the sizzling-end of note is less distinct. While, glockenspiel instrument have a nice bell-like dings to them.

- Electronic sounds like zings, rings, and e-guitar notes are clear, but they lack the sharpness that would make them more distinct.

- Overall, the treble lacks a bit of bite, reducing its overall definition, and there’s a consistent layer of haziness in the treble that slightly dulls its clarity.

- The upside is that it’s well-suited for treble-sensitive listeners and long listening sessions, focusing on subtle presence and ease of listening. It strikes a good balance between smoothness and crispness.

- In other words, it’s not designed for treble-heads seeking intense sparkle but rather caters to the majority of audiophiles who prefer a more balanced approach.

✧ ════ •TECHNICAL PERFORMANCE/ASPECT• ════ ✧

- The STAGE-DIMENSION is rather solid. It sounds wide and spacious with acceptable perceived depth to the stage.

- IMAGING performance is on par with most of its rival. It’s very good capturing the dynamic ambience of the recorded revenue. As for instrument and vocals, they're placed accurately between two channels but doesn't give off that pin-point sharp image definition.

- For a hybrid setup of 2 drivers, the SEPARATION level is mostly average. The separated elements don’t have the clearest of cut where each of them have a clear distinct spot in the mix. However, it managed to maintain each border of sound more consistently than not, preventing from busy tracks to sound overly congest or compress.

- When it comes to DETAIL HANDLING, it is not class leading but it is not terrible either. It is acceptable for the price even by today's standard.

- DYNAMICALLY it doesn't have alot to offer. As mentioned, having a safer tuning can sometimes sacrifice the musicality of one's music. It is not a set you sing and dance along with. The vocals just don’t sound as soulful meanwhile instrument replay lacks expressions. And eventually, one will get bored of it.

- Regarding its TONE and TIMBRE, despite, it's compressed micro-dynamics, it still sounds fairly natural thanks to its well balance tonal temperature.

- When it comes to VOLUME SCALING. It performs quite well from low to mid volume. In fact, it is best at mid-volume listening. Any higher, the mid-bass will start to lose control while the uneven response of the treble will start to show up. Listening it too low will dampened its dynamics to a flatter degree.

- The DRIVER is not the most capable I've heard. On certain occasion it started to show its limit. Driver coherency is good but not excellent. On a demanding track, the bass can sound slower while the mid-range and treble have faster decay and lighter on note-weight. Thankfully, there is no driver-flex or pressure built up issue through out the test.

◤FINAL THOUGHTS◢
My final assessment with the BQEYZ FROST had left me with a mixed feeling. There are parts of it that is good but there are also parts of it that is turning me off. It is not a set that will impresses you on 1st minute and it is not a set you would want to keep listening either. With a 179$ price-tag, it is not easy to recommend when considering its overall sound quality. Preference aside, the Frost then is still a decent product if you’re looking for a laid-back, warmish, neutral signature but only if you can get it on a discount.

DUNU DK3001BD 4½★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
The tuning is neutral-bright with a mild sub-bass boost. Following the "META" tuning, it features a reduced ear gain and a linear presence in the lower mid-range. The mid-bass is slightly subdued, but the treble extension is excellent, although it may be a bit too bright for some listeners.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- While the bass is elevated, it leans more toward a sub-bass oriented. The focus is on control and precision rather than raw power.

- The sub-bass though is deep and rumbly, is better described as tight and punchy. It delivers a quick, immediate impact rather than being a sustained vibration. Even at higher volume, it retains this character, offering a clean, defined rumble without being overwhelming. If you're expecting a deep, resonating sub-bass, this isn't it.

- The mid-bass presence is sufficient, but the upper bass region could use more substance. As a result, percussions like drum strike doesn't slam at full range. Bass guitars, in particular, seem to suffer, especially in rock and metal genres, where they sound somewhat muted, lacking fundamental presence compared to other bass elements. However, kick drums and toms are more satisfying, sounding punchy and snappy with a more dynamic feel and impact.

- Despite the upper-bass lacking that extra reach, it is not severely lacking. Additionally, ghetto-bass tracks have a nice bouncy feel. Bass drops are clean and precise in their replay.

- Bass enthusiasts will likely appreciate the quality of the bass more than complain about the lack of sheer volume or power in the overall bassline. In other words, while it's not tuned for hardcore bass-heads, it is excellent for those who prefer a more refined bass experience.

▓▒░ MID-RANGE /VOCAL ░▒▓
- The mid-range/vocal leans toward a lean-neutral tone, prioritizing clarity, transparency, and precision. It reveals subtle details in vocal phrasing, such as breath sound and vocal fry while maintaining a neutral natural balance—avoiding any exaggerated warmth or brightness. These fine details contribute to a more immersive listening experience.

- This is one of the few sets that can accurately place vocals in the mix. Depending on the track, the vocals can sound intimate or slightly pushed back, but they never feel recessed, whether male or female.

- The mid-range separation is exceptional, with excellent vocal distinction within the mix. This allows each voice to be heard clearly, making it one of the more capable mid-centric sets. Despite its analytical nature, the mid-range is crisp yet smooth, without noticeable harshness or sibilance.

- However, it's not flawless. The mid-bass is somewhat tucked, which can cause vocals and instruments to lack a certain body, especially if you're used to a fuller, richer sound. One thing to note is that with leaner, brighter sources, the vocals can sound dry, which may impact the warmth of male vocals, male vocals may come across as even leaner or thinner, which is less than ideal.

- Another minor drawback is the lack of dynamic vocal presentation. The natural rise and fall in vocals aren’t as pronounced, with some of the emotional depth and expression in vocal intonation feeling suppressed (especially, on lower volume). This also extends to instruments like pianos, violins, strings, and guitars, where the initial attack feels more restrained, and there's a slight lack of note-weight and sustain. On the plus side, it never becomes shouty or screechy.

- Overall, its mid-range often delivers the lyrics in a clear and straightforward manner, without excessive ornamentation or distractions at the expense of a slight emotional touch.

To address these issues, you could try EQ adjustments, boosting the mid-bass (100-300Hz) and upper-mids (3-5kHz) by 1-3 dB for a welcoming improvement.

▓▒░ TREBLE/HIGHS ░▒▓
- This has got to be one of the best treble performances I’ve heard in 2024. It's produced by six drivers on each side, consisting of 2 balanced armatures and 4 micro-planar drivers combined. Yes, it is bright leaning, but what it delivers is simply spectacular. It never seems to lack in extension at all. The treble shines with great finesse without overbearing brightness. There is hardly any peaks, harshness, sibilance, graininess, haziness, or metallic sheen—issues often found with BA and planar drivers.

- As a result, the treble delivery is just so pristine yet so effortless. It’s highly detailed without feeling forced, with everything unfolding naturally and presented with excellent transparency and refinement. It strikes a good balance between smoothness and crispness.

- Cymbals and Hi-hats have a remarkable timbral accuracy, capturing its delicate high-end shimmer. While drum snares are no different with its crispy high-pitched rattling sound. Even synthetic noises, such as electronic zings, rings, buzzes, and electric guitar, retain a satisfying bite and crunch on replay.

- With the right synergy, the treble response can become incredibly smooth, making it easier to the ears during long listening sessions, while still providing plenty of detail for critical listening.

- However, on brighter pairings, it may come across as a bit sharp. Treble-sensitive listeners might prefer pairing it with a warmer source to smooth out the added brilliance. Its analytical nature also means it’s less forgiving with poorly recorded tracks. Additionally, on lower bitrate files, you might notice slight compression, which is worth mentioning.

For $500, achieving this level of treble performance is no small feat. To surpass such quality, one might have to enter the kilo-buck territory, which speaks volumes about its value.

✧ ════ •TECHNICAL PERFORMANCE/ASPECT• ════ ✧

- The SOUNDSTAGE is not particularly expansive or grand, but it offers a good sense of openness and spaciousness. It’s quite wide, with impressive headroom and just average depth. Vocals are positioned neutrally within the stage, with their placement varying depending on the size of the recorded venue.

- The IMAGING capabilities are highly competent, providing accurate, pinpoint-sharp definition. The transition and localization of sound between channels is seamless.

- The pitch-black background greatly enhances the LAYERING AND SEPARATION. Combined with its immaculate treble performance and highly controlled bassline, it makes dissecting and separating job sound so seamless. It can handle highly complex tracks with without breaking a sweat. The ability to separate sounds and present a well-layered music is one of its key strengths.

- Its DETAIL HANDLING is truly class-leading, punching well above its price range. Its resolving power to capture fine nuances in both vocals and instruments is impressive and shouldn't be overlooked.

- DYNAMICALLY, it isn't tuned for fun or engagement, which limits its overall dynamic range. The focus is more on control and precision. As a result, there are moments when vocals and instruments lack micro-dynamics, such as subtle shifts in a vocalist's volume or slight variations in the loudness of background instruments, which can sound somewhat compressed. These small changes in sound are what contributes to the "feel" of a performance, which create a sense of natural flow and expressiveness in the music.

- Regarding its TONE and TIMBRE, despite its bright nature, it sounds more analogue/organic than hi-fi/digital-like. However, the lack of note-weight/body and overtone/reverb somewhat takes away some of the realism of its timbre. The notes could benefit from a wider attack-range, longer sustain and decay to create a more natural sense of realism. Despite these minor drawbacks, it will never sound unnatural, which is worth noting.

When it comes to VOLUME SCALING , it remains quite linear. Even at higher volumes, both the bass and treble stay well-behaved. There’s hardly any boominess or glaring issues throughout the test. In fact, it’s best enjoyed at a louder volume—listening at quieter volumes can make the music sound lifeless and uninspiring, unless paired with a bright, energetic source.

Dunu has certainly chosen their DRIVERS wisely. There’s no sense of them cutting corners in terms of driver quality. Despite using 9 drivers on each side, the coherence is exceptional, and any contrast in timbre is barely noticeable. On top of that, there’s no driver flex or pressure build-up, which is a positive.

✧ ════ •POTENTIAL SYNERGY TWEAKS• ════ ✧

EARTIPS : I’d say, ditch the stock eartips. As it tends to emphasize the treble zings and reduce the bass presence even more. I just stick with SPINFIT CP100, it helps with the bass body and vocal intimacy while taming that mid-treble spiciness. One thing to note, due to its wide nozzle, it best not to force fitting those small diameter step onto it as it can considerably damage the stem of the tips.

DAC/AMP: As mentioned on the "treble" section, it is a tricky one. I find it best to pair with clean, less coloured, perhaps more mid-centric source. Something like the Tanchjim SPACE will do job just fine on lower listening volume. Pairing with something warmer ( ZenDAC v2/ xDuoo Link2BAL/ Tanchjim Luna) is better people who loves to listen loudly.

✧ ════ •BUILD/ PACKAGING/COMFORT• ════ ✧
- The build quality looks and feels far better in person than in pictures. The metal shell features a "Cyberpunk"-inspired design that’s unique to this model, and it has a cold, premium feel to the touch.

- As with most DUNU products, the unboxing experience is exceptional. It includes everything you could possibly need, from ear tips and swappable plugs to a cleaning tool and a practical carrying pouch. Every component exudes quality, especially the stock cable.

- In terms of comfort, it may be an issue for some. Due to its rather bulky shell, it’s not particularly heavy, but it may feel a bit too large for smaller ears. However, with the right fitting ear tips, this discomfort can likely be reduced.

HEAD-2-HEAD
vs LetShuoer EJ07 x Hakugei Skyrim x Pentaconn Coreir PTM02 ALLOY (MS)

BASS
- Both have a sub-bass focused bassline, but the EJ delivers a more atmospheric sub-bass that envelops the music. The rumbling and droning sensations are more pronounced, with greater pressure and sustain. The BD, while offering better detail and texture, doesn’t quite match the power of the EJ’s sub-bass.

- In the mid to upper bass regions, the EJ stands out with a stronger presence and better decay. Kick drums and toms hit deeper and with more impact, while drum strikes have a wider transient. The bass guitar is more prominent in the mix, and the cello has a fuller, heftier tone.

- Overall, the bass on the EJ flows more freely, with dynamic bass making the low-end sound more engaging, despite the EJ being a basslet set overall.

MID-RANGE/VOCAL
- The EJ is the more mid-centric of the two, with the mid-range (vocals and instruments) occupying the most prominent space in the soundstage. It offers greater intimacy and immersion, with vocals sounding slightly fuller, lusher, and smoother, giving male vocals a better sense of body. The BD, on the other hand, excels at highlighting subtle nuances in instrument and vocal textures, such as breathiness, hoarseness or raspiness. The sense of airiness to the voice benefits female vocals the most.

- In my opinion, neither set offers the best vocal dynamics. However, the EJ feels less restrained at the higher end of the vocal-range compared to the BD. particularly on higher-pitched or female vocals.

- The BD also provides realistic instrument reproduction, with guitar plucks having a more pronounced twang, piano taps sounding more solid, and the violin/strings strums carrying a more satisfying accent.

- The vocal rendition on EJ can sounds a tad more euphonic at times—clean and clear with minimal coloration. However, in terms of overall vocal and instrument timbre, the BD sounds more natural, despite its leaner presentation.

TREBLE
- Right from the start, the EJ sounds darker in comparison. It lacks the airiness and crispness of the BD, and its more laid-back treble makes it a safer choice for treble-sensitive listeners.
- Although less bright, the pitch-black background still provides a good level of clarity for the treble. High-end details are present, though they’re less prominent.

- Due to its shorter decay and sustain, the trailing shimmer of hi-hats or cymbals is less noticeable. High notes on the BD, on the other hand, sound more complete with a crisper and more substantial note weight.

- The smoother note edges of the EJ make electronic zings, buzzes, or rings sound less harsh or sharp. Depending on your preference, the EJ may be better suited for electronic music, with the smoothness of its EST treble being a particular treat.

- Being less analytical also means the EJ is more forgiving with low-fi recordings, where flaws in poorly produced tracks are less noticeable or distracting.
- In short, both the EJ and BD take entirely different approaches to their treble delivery.

TECHNICAL PERFORMANCE
- The imaging on the EJ is still accurate, but the image definition is not as sharp. While the layering and separation on the EJ are impressive, the BD is better at dissecting musical elements, effortlessly creating more distinct layers.

- As a result, the BD offers higher overall resolution, highlighting intricate details and providing a better range of micro-dynamics, which enhances the "feel" of a performance.

- As noted, the timbral accuracy on the BD is noticeably higher, sounding more organic and realistic. The EJ’s smoother, less focused, and less dynamic traits slightly diminish the naturalness of its timbre.

- In terms of build and comfort, the EJ’s resin shell feels cheaper in comparison, but its lighter and smaller design makes it more comfortable for smaller ears.

“If you appreciate timbral accuracy, resolution, or a highly technical capable set, that is less coloured in its approach, the DK3001BD is a clear winner. However, if you prefer a mid-centric set that offers intimate, lush vocals with a more subdued treble while still maintaining a solid level of technical performance, the EJ07 is a great option—that only if you can find one, as it has been discontinued.”

◤FINAL THOUGHTS◢
Since its release, the DK3001BD has generated quite the hype. And I was fortunate enough to own and evaluate one myself. After a week of listening, it's easy to see why it’s so highly regarded. To my ears, it’s not a set that will immediately impress, but the longer you listen, the more it grows on you. Its technical capabilities are truly impressive, and combined with its exquisite timbre, it makes for an exceptional set. While this "META" tuning may not appeal to everyone, I believe the Dunu DK3001BD will set a new standard moving forward. At just under $500, the performance and refinement it offers are mind-blowing. I suppose the real meaning of BD isn’t "brain dance" but "BASED DUNU!" XD.

NFACOUS NM20 3★★★

MSRP : US$118.99 Driver Configuration : 1- MC2L-100P Dynamic Driver

~ SHORT REVIEW ~

▓▒░ SOUND-SIGNATURE ░▒▓
It is tuned with a V-shaped sound profile, featuring a bright tilt in its tonal balance. The bass is boosted with a slight emphasis on the mid-bass. The mid-range is recessed, yet still preserves a natural vocal presentation. The treble delivers a good amount of brilliance, allowing it to cut through the lower frequencies effectively

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- Right off the bat, the bass sounded fast, clean and well-controlled. It’s not about quantity, but rather delivering the necessary presence whenever called for.

- The sub-bass roll-off is noticeable on tracks that focuses sub-bass. While the sub-bass rumble has good texture, it feels light, lacking in pressure and sustain.

- The mid to upper bass has a slightly slower decay and delivers a wider range of attack. As a result, percussion, such as drum hits, offers a more satisfying slam, while kick drums pack more than enough punch. The bass guitar, however, has a more subdued presence in the mix.

▓▒░ MID-RANGE /VOCAL ░▒▓
- Despite its recessed nature, both male and female vocals don’t come across as too thin or dry. Some may find them lacking in body and fullness, but it remains acceptable for a V-shaped sound signature. In terms of vocal texturing, it manages to highlight the important nuances without sounding harsh.

- Higher-pitched or female vocals in the upper octaves tend to have a more forward presence, while deeper male vocals are slightly pushed back in the mix. In other words, female vocals offer a more rewarding performance, with an airy texture that isn’t overly sharp.

- Thanks to its emphasis on the upper-mids, instruments like guitars, violins, strings, and wind instruments stand out more, with a rounded edge to their attack.

▓▒░ TREBLE/HIGHS ░▒▓
- The emphasis from the lower to mid treble is quite noticeable, but beyond that, there's limited air-extension.

- While it may not have the most even treble response, the noticeable peaks and dips help give the treble elements a better sense of contrast. However, depending on the track, this characteristic could bring out sibilance or unwanted resonance, though most of the time, it remains tolerable.

- Cymbals, hi-hats, and drum brushes sound inoffensive, with a surprisingly tame presence. The same applies to synthetic noise like electronic zings, rings, or even electric guitar. The attack is on the smoother side, and treble-heads may find themselves wishing for more bite in high-pitched percussion.

✧ ════ •TECHNICAL PERFORMANCE/ASPECT• ════ ✧

- In terms of STAGE-DIMENSION, it feels closer to 2D than 3D. It plays with more width than height. There isn't much perceived front to back layering which restrict the depth of the stage.

- The IMAGING PROJECTION is average at best. While the left-to-right instrument placement is generally accurate, it lacks precision in terms of image definition, not being pin-point sharp.

- The LAYERING and SEPARATION are good, but not exceptional. Like most single dynamic drivers, the separated elements tend to sound closer together. The background isn't completely black, with a consistent layer of haziness that slightly impacts the clarity of the separated elements. On simpler tracks, however, it performs just fine.

- Overall, the DETAIL-RETRIEVAL is typical for its price range—nothing extraordinary.

- DYNAMICALLY, the softer attack does take away some of that dynamic feel on transient. The elements of loud and soft can still be heard but lacks distinctiveness.

- The TIMBRE, given the tuning, has a sufficiently analogue quality. There are no noticeable digital artifacts that impact the naturalness of its timbre. The note weight is adequate, though not excellent. The notes generally have good sustain with fairly precise decay. While the attack is fast, it could benefit from more impact. With a V-shaped sound profile, the TONAL BALANCE is inevitably compromised, but it is still well-executed and quite decent in its approach.

◤FINAL THOUGHTS◢
Having experienced several versions of Harman-like tuning, the NM20 brings something different to the table. While its tuning approach isn't groundbreaking, it certainly occupies a niche in today's market. At a $118 price tag, it could offer more, but it's not a bad option. It may not be for me, but for those with an acquired taste, I can see them enjoying it—especially if you're seeking a decent, bright-leaning V-shaped sound.

KIWI EARS QUINTET 4½★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
It is tuned with a mild V-shaped sound profile, where the bass is enhanced to add warmth to the tone. The mid-range is both rich and smooth, while the treble extends well without overbearing brightness. This creates a well-balanced sound, making it suitable for a wide range of music genres.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- The bassline takes a more balanced approach, rather than a bass-heavy tuning. The low-end is consistently tight, punchy, and well-controlled. There is minimal bleed into the mid-range, which helps preserve clarity across the sound.

- The low-end emphasizes the sub-bass, offering sufficient extension and density. The rumbling, humming, and droning elements have a strong presence and sustain, creating a subtle vibration and texture without becoming overly bloomy. Ghetto bass playback maintains a lively bounce while accurately rendering bass-drop elements.

- Although the focus is on the sub-bass, the mid to upper bass is far from deficient. Its linear and consistent presence adds warmth and body to instruments like drums and bass guitars. Kick drums in particular, have a satisfying airy depth to their "thud," adding a sense of air movement. As a result, the punch and slam are impactful, delivering a tactfully satisfying replay.

- In terms of quality, it's one of the best I've heard in its price range. The bass is present but not overpowering, with good depth and layering that enhance its overall texture. It remains well-controlled, even on bass-heavy tracks. It is quite a fun bass to listen to. That sense of bounciness coming from its 10mm DLC makes it quite addicting to listen. This particular trait has been missing on most recent sets I've tested.

▓▒░ MID-RANGE /VOCAL ░▒▓

- The mid-range without a doubt is one of its strongest assets, with its clear, smooth, lush and natural vocal presentation, be it male or female. The tonal balance allows it's mid-range to appreciate nuances, giving it a good level of transparency without sounding harsh or gritty.

- The slight warmth coming from the lower harmonics gives extra oomph to male vocals and instrument (guitar, piano, strings) the fundamental body that it needs. It is done well without sounding too thick or veiling higher pitched instrument and vocals too much.

- Meanwhile, the female vocals, violin, and electric guitars maintain enough energy and presence without sounding flat or dull. They avoid becoming shouty or screechy. However, this can result in the higher-pitched vocals sounding a bit too safe on the vocal transients, lacking that final burst of emotion, especially compared to a set with more precise vocal intonation.

_ Overall, for a balanced armature driver, the mid-range timbre is natural and pleasing to the ear. The attack is neither dull nor overly sharp, and both the sustain and decay are rather precise. The notes have a pleasing weight, with a noticeable presence of reverb. All of these factors contribute to vocals and instruments sounding authentic and distinct.

- Despite the minor critiques, to my ears, this is where the musicality factor comes. Most audiophiles will likely appreciate this set most when listening to vocal-centric music.

▓▒░ TREBLE/HIGHS ░▒▓
- This is my 1st encounter listening to a micro-planar transducer (MPT) combined with Piezoelectric Bone-Conductor driver (PZT) handling the highs. To my surprised, It is quite impressive. The treble has a proper extension. It is crisp yet very smooth in its response. The air-extension is not abundance but plentiful which gives off spaciousness or airiness to the stage. While it is clear and has a noticeable presence, it is not overly sharp or harsh on its attack.

- For high percussion instruments like constant hi-hats, cymbals, and drum brushes, the shimmering elements are neither metallic nor harsh, yet they maintain a solid weight on the transients. They feature precise decay and excellent sustain, allowing high notes sounds complete from end to end without masking other elements in the mix. The same applies to the snare drum, where the hits don’t feel overly sharp or intrusive. Electronic sounds like zings, rings, rattles, and ticks come across as natural and unobtrusive.

- The defining treble elements are well laid-out. It is clear and well-articulated. None of the treble detail sounded forceful. It is bright and detailed, but it doesn't cross the line of sounding harsh or fatiguing territory. There are no undesirable treble qualities like peaks, graininess, haze, or sibilance. The MPT and PZT drivers responsible for the highs have done an excellent job preserving transparency without excessive brightness, making it enjoyable for most audiophiles.

✧ ════ •TECHNICAL PERFORMANCE/ASPECT• ════ ✧

- The HEAD-STAGING is fairly wide. Headroom is not that tall but there is a good sense stereo depth which allows for a proper front-to-back layering. Vocals are well-centralised that is slightly to the fore, surrounded by images of instrument.

- IMAGING PROWESS is mostly accurate but in terms of image definition is not the sharpest in class. Regardless the localization or positioning of sound between channel is clearly presented.

- Due to its spacious stage and darker background, the INSTRUMENT SEPARATION is excellent, especially in dense or busy tracks. It does a great job of keeping elements distinct without them overlapping or blending together. They have good spaces between them without sounding congest or compress. The clarity across all frequencies allows for easy distinction of instruments, even in busy tracks. This is particularly beneficial in genres like progressive rock or symphonic metal, where complex arrangements demand great separation and detail.

- When it comes to DETAIL RETRIEVAL it is nothing short of competent. With the works of five well-implemented drivers, it is quite capable of resolving intricate details in the music without breaking a sweat. Micro-detail such as the breath or coarse texture on vocal phrasing, the subtle decay of cymbals, or the fine overtone on string instruments can be captured. It is capable of presenting details in a way that feels refined and defined.

- DYNAMICally, it is not tuned to sound super energetic or aggressive in its nature, but it is not relax either. It sounds more than lively to keep your music alive. It manages to distinguish the elements of soft and loud in the mix rather well.

- When it comes to TONE & TIMRE, to my surprise, despite having 5 different drivers on each side, the word "Unnatural" not once has passed my mind. It is certainly unique. It can sound fast yet warm at the same time. The attack is subtle but impactful, the rate of decay is mostly accurate, the notes have good sustain and are nicely weighted. Sure, one could nit-pick that its vocal rendering could use with more body to sound more natural but that’s about it.

- It SCALES with VOLUME really well. Thanks, its well-balance yet evenly response tuning. One could really crank-up the volume if they want to. I didn't notice the any distortion with my highest listening volume.

- Through-out the assessment, there has never been a sign of cheap DRIVER. The implementation is nigh perfect. Those 5 different drivers truly work in harmonic. There is a slight timbre-contrast when transitioning from the bass to mid-range, but it is very minimal. There is no driver-flex or pressure build-up issue which is great.

✧ ════ •POTENTIAL SYNERGY TWEAKS• ════ ✧

- EARTIPS : The stock ear-tips works just fine but if you want a more open listening experience. I'd recommend using a medium-bore ear-tips. Such as Kiwi Ears Flex Silicone or Hillaudio MS400 (if you're a Malaysian). It does make it more open and more balance sounding.

- DAC/AMP: Mercifully, it not that picky on sources. Due to its well-balance sound, It can runs with pretty much anything.

✧ ════ •BUILD/ PACKAGING/COMFORT• ════ ✧

- Though the build quality is not the most premium, but it sure feels solid and durable to the touch. The design is very minimalist with simple looking metal grey satin faceplate.

- Like most Kiwi-Ears, the unboxing experience is nothing to talk about. There is no 4.4 balance cable option. But it does provide you with small usable carrying case and with 6 sets of silicone eartips, ranging from small to wide bore with 3 different sizes each. For a $219 it could be better. But I have no major complaints as it gets the job done just fine.

SHORT COMPARISON
vs KIWI EARS QUINTET (STOCK) x HillAudio MS400 eartips.
- ORCHLITE sounds more mid-bass oriented vs the sub-bassy QUINTET.
- QUINTET sub-bass has better presence and texture.
- ORCHLITE mid-bass hits deeper and harder.
- ORCHLITE is more vocal-centric. Vocal sounds richer, fuller, and more intimate.
- QUINTET has a slight edge on highlighting nuances on vocal texturing.
- QUINTET has greater treble-extension. It sounds crispier, airy-er and more energetic up top.
- ORCHLITE inoffensive treble is safer for treble sensitive folks.
- QUINTET is a wider stage while ORCHLITE plays with more depth.
- QUINTET stereo-imaging is sharper and more accurate.
- QUINTET separation prowess ability is a class above.
- QUINTET detail retrieval is a smidge better.
- ORCHLITE will deliver a more cohesive sound.
- QUINTET have a slight advantage on timbral accuracy.
- QUINTET is more versatile for variety of genres.
- QUINTET has smaller shell which makes it more comfortable for most user with no pressure built-up issue.
- QUINTET offers a greater price-performance value.
- ORCHLITE shells are better build, it feels sturdier and more durable.
- QUINTET is slightly cheaper to own.
- BOTH are equally easy to drive.

"If you're looking for a mid-centric set that is warm, lush with great intimacy, the Orchestra-Lite is an easy pick. But if you value, technical performance, engagement and timbral accuracy, the Quintet is the one."

◤FINAL THOUGHTS◢
This sets have been around for quite a while but it got overshadowed by endless released of Chifi-products which is a shame because the Quintet is definitely one of the Kiwi Ear's best. With its uncommon driver configuration, it is certainly unique on its own. But more importantly, it seems to work. If you're looking for this sort of sound-signature, for the money, I’d recommend it wholeheartedly, I'm pretty sure you won't disappoint. Because to my ears, it is my favourite KIWIEARS to date.

KIWI EARS ORCHESTRA LITE

One of the more natural sounding all-BA sets…

Pros:
- One of the more natural sounding all-BA sets.
- One of the better BA bass I've heard.
- Rich and smooth vocal presentation.
- Inoffensive treble response.
- Easy listening experience.
- Beautiful translucent shell.

Cons:
- It is still BA-bass, nevertheless.
- Vocal can sound abit too forward in the mix.
- A slight dullness on transient.
- Not the most technical All-BA sets.
- Potential fit issue.
- No 4.4 balance Option.
- Bland unboxing experience.

[MY PERSONAL HEAD-FI GRADING]
1 ★ - Appalling! please avoid this!
2 ★★ Subpar offering, there are better options out there!
3 ★★★ Decent with some caveats! Not a bad pick!
4 ★★★★ Not perfect but solid choice ! This should be in your shortlist. A nice addition to your collection.
5 ★★★★★ One the best in class! You should go right ahead & buy one! A must have!

KIWI EARS ORCHESTRA LITE 4 ★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
It is somewhat warm but clean, neutral sound. The bass is mid-bass oriented with a tasteful warmish coloration. The mid-range will sound more to the fore while the treble is just chilling at the back of your music.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- It is an all-BA set. So, be sure to cater your expectations beforehand. However, this has got to be one of the better BA bass I've heard recently. It is boosted but it is more a punchy than rumbly type of bass with a slight warm coloration to the tone.

- On a sub-bass focused track, the sub-bass roll-off it quite noticeable. Having said that, the lack of sub-bass pressure and sustain does not bring detriment to your music. You’ll still hear it, but you just don't feel it. For as long as you don't expect a highly textured and vibration subs, you’re not going to disappoint.

- The sub-bass performance may not be all impressive. Thankfully, the mid-upper bass presentation makes up for it. It sounds thick, full-bodied, tight, and punchy, giving drum-kits, bass guitar a good presence in the mix. Kick-drums has a satisfying texture and kick to the thuds. The attack on percussions hits deeper and harder than one might expect with a good sense of natural weight behind those hits for added engagement.

- From a BA bass standpoint, the bass is clear and well-textured, without excessive bloat or boominess. It won’t necessarily satisfy a dedicated bass connoisseur, but it provides a solid bass presence to fill the lower spectrum of your music.

▓▒░ MID-RANGE /VOCAL ░▒▓
- The mid-range is where it will shine the most. If you love your intimate vocals to sound warm, lush and rich then this set might be the one for you. The tuning ensures that both male and female vocals come through naturally and smoothly. Though vocal texturing is on the smoother side, it is void of any dryness or harshness timbre that are often exhibits with a monitoring set.

- Despite its fuller, thicker and smoother approach, the vocal is well-articulated. The intonation on vocal transient still maintains its accuracy. Which means both male and female vocal will come across equally as engaging which is more apparent on duet. The same true can be said with instruments like piano, guitar, violin and flute. They have good tonal weight with a smoother note edge to them.

_ There are times when the vocal can sound at tad too forward in the mix, causing a slight hotness on vocal transient. However, with the right selection of ear-tips, this issue can be reduced.

- To those who prefer a more "angelic" female vocals, then perhaps this set is not going to be it. Especially on higher octave, the female vocals can sound a tad too husky. This sort of tonal balance is better suited for chesty male vocal. Depending on your preference, it’ll work just fine.

- Having said that, in listening experience, the mid-range/vocal presentation is what makes this set such a nice and easy to listen which favours euphony over transparency.

▓▒░ TREBLE/HIGHS ░▒▓
- The warm hues coming from the lows do contribute to that treble sounding generally on the darker and relax side. It does extend fairly well up in the highs with a noticeably roll-off upon entering air region. For listeners who enjoy a bright and airy presentation might find it lacking in sizzles and sparkling up-top.

- The evenly treble response and the clarity it provides makes it easy to be appreciated. There is no issue with sibilance, sharpness or discomfort. If you're sensitive to treble, this is a set for you.

- High percussions like constant hi-hats, cymbals and drum brushes will sound further back on stage. While synthetic noise such as electronics and e-guitars will have a rounded edge to the notes. As a result, treble elements can somewhat sound duller in transient. Though, it is not overly blunted.

- Thankfully, it doesn't sound muddy or smeary. In short, the treble though present, they don't really stand out that much. Which can be a deal or break to some.

✧ ════ •TECHNICAL PERFORMANCE/ASPECT• ════ ✧

- The SOUNDSTAGE is adequate, offering a sense of depth and space, but it is not particularly wide or holographic. It’s more of a focused presentation that’s intimate rather than vast.

- IMAGING-PROWESS is again average. Instrument placement is accurate, but in terms of localizing image it is not the sharpest.

- Which also affect its INSTRUMENT SEPARATION ability. Right of the bat, everything will sound closer to each. It is fine on a simpler arrangement but on a more complex tracks, it will start to struggle to keep each elements sound distinct without overlapping or blending together.

- The DETAIL-RETRIEVAL may not be its forte. For most listeners it is fairly detailed. But for a critical listening, it is better to find more resolving sets. It favours ease of listening over intensity of detail.

- DYNAMIC-RANGE on this set is not particularly wide. The elements of loud and soft can still be distinguish but it is not that distinct which can take away some of that liveliness from your music.

- For an all-BA set, Its TONE & TIMBRE is one of the more natural setups I've heard. It doesn't sound as plasticky or weightless as some of its counterpart. The bassline especially sound more organic than one would expect. Overall, the notes have adequate note-weight with natural decay.

- Like most all-BA sets, VOLUME SCALLING is not going to be that high. It best to listen at around low to mid volumes. Anything higher can cause the bass to sound too boomy. Meanwhile, the vocal can sound overly forward.

- DRIVER QUALITY is general good. It sounds cohesive without any graininess or distortion issue. Driver-flex is not a problem here as long as you used the right ear-tip to reduce some of the pressure-build up on longer sessions.

✧ ════ •POTENTIAL SYNERGY TWEAKS• ════ ✧
EARTIPS: The stock tips are useable, but it is not the best sonically. I'd recommend using wide-bore tips as it helps to open-up the treble just a tad, giving vocal and treble elements more room to breathe. For this assessment I stick with either Moondrop Spring tips or Tangzu Sancai Balance tips.

DAC/AMP: Due to its warmer and laid-back tuning, it is best to use a more technical and brighter DACs like the Tanchjim SPACE for added technical boost and treble bite.

✧ ════ •BUILD/ PACKAGING/COMFORT• ════ ✧
- The translucent resin shell is so beautiful to look at. You can peek the drivers clearly. It is solidly built and feels durable to hold.

- The shell is size is larger than usual. If you have a smaller ear, you might want to demo it prior purchasing it.

- Like most Kiwi Ears, the unboxing experience is too bland. There is no 4.4 balance cable option. But it does provide you with small usable carrying case and some ear-tips for you to try. For a $249, I was expecting more.

SHORT COMPARISON
vs KIWI EARS QUINTET (STOCK) x HillAudio MS400 eartips.
- ORCHLITE sounds more mid-bass oriented vs the sub-bassy QUINTET.
- QUINTET sub-bass has better presence and texture.
- ORCHLITE mid-bass hits deeper and harder.
- ORCHLITE is more vocal-centric. Vocal sounds richer, fuller, and more intimate.
- QUINTET has a slight edge on highlighting nuances on vocal texturing.
- QUINTET has greater treble-extension. It sounds crispier, airy-er and more energetic up top.
- ORCHLITE inoffensive treble is safer for treble sensitive folks.
- QUINTET is a wider stage while ORCHLITE plays with more depth.
- QUINTET stereo-imaging is sharper and more accurate.
- QUINTET separation prowess ability is a class above.
- QUINTET detail retrieval is a smidge better.
- ORCHLITE will deliver a more cohesive sound.
- QUINTET have a slight advantage on timbral accuracy.
- QUINTET is more versatile for variety of genres.
- QUINTET has smaller shell which makes it more comfortable for most user with no pressure built-up issue.
- QUINTET offers a greater price-performance value.
- ORCHLITE shells are better build, it feels sturdier and more durable.
- QUINTET is slightly cheaper to own.
- BOTH are equally easy to drive.

"If you're looking for a mid-centric set that is warm, lush with great intimacy, the Orchestra-Lite is an easy pick. But if you value, technical performance, engagement and timbral accuracy, the Quintet is the one."

◤FINAL THOUGHTS◢
This set has been around for more than a year now. In an all-BA market, I still find it relevant. It has no major flaws other nit-picks. It is very easy to listen to. And I believe it will be appreciated by many especially to those all-BA enthusiasts.

CELEST CD-20 4 ★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
The sound it carries is definitely neutral with a slight sub-bass boost. The mid-range has minimal coloration with an adequate treble reach, creating a well balance sound that is clean, clear and truer to the gears

▓▒░ BASS/LOW-ENDSOUND ░▒▓
The low-end has a slight bass boost without overpowering the upper-registry. The bass is more about control and tightness, rather than sheer power.

Though the sub-bass has a slight dominant, it is not the deep and rumbly type. It gives off a quick, immediate impact rather than sustaining its energy. Hence elements of throbbing, booming or vibrating is not going be the most atmospheric.

The mid-to upper bass is quite linear and well balance. It adds sufficient fullness and warmth without spilling over onto the mid-range. The attack is punchy and tight. Kick drums have a soft yet deep "thud" to the kick. Bass guitar doesn't sound bloated with a clear and well-defined tone to it. This also helps in giving electronic music a nice sense of liveliness to them.

Overall, the bass quality is no slouch. The layering and detailing is solid while providing ample of energy to keep the lows engaged.

▓▒░ MID-RANGE /VOCAL ░▒▓
The mid-range/vocals have a slight forwardness to them. Vocals and instruments are presented clearly with good level of detailing. It comes across as fairly natural and smooth, void of any harshness or muddiness. The interaction between the bass and the treble region makes the mid-range almost uncoloured.

Both male and female vocals are very well articulated. The voice doesn't sound too thin or too thick. It can pick-up subtle nuances on vocal phrasing or even audible artifacts on instrumental replay with ease. The more precise intonation to the voice allows the singer to express their emotions more accurately. Which means vocal rendition particularly sounds more immersive to listen to.

It may not be the most mid-centric tuning, but its mid-range presentation is one of its strong point. It manages to hit the right balance between euphony and clarity.

▓▒░ TREBLE/HIGHS ░▒▓
Tonally, the treble is best describe as being neutral. It is well-extended up until the mid-treble region with a gradual roll-off upon reaching the air-region. As a result, the highs have good level of presence and crisp while maintaining a smoothness that prevents it from sounding too sharp or shrill.

The slight emphasis on the low to mid treble region, gives high percussions like constant hit-hats, cymbal crashes or drum-snares a natural presence. They have a rather precise decay as they don't linger unnecessarily. Synthetic noise such as electronic zing and ringing has a more rounded edge to them. While electric guitar has just about enough bite.

The defining treble elements are laid-out with great subtleties. The treble brilliance is plentiful, but it is never intrusive. This makes it an excellent pairing for long listening sessions.

In short, the treble delivery is well-defined and refined.

✧ ════ •TECHNICAL PERFORMANCE/ASPECT• ════ ✧
The SOUND-FIELD gives off a wide, open stage that provides a good sense of space and dimension to your music. It may not offer the most expansive stage in its class but the sense of depth, width and headroom it offers is more than spacious.

The IMAGING capabilities is no slouch. The positioning of sound is accurate but not the sharpest in class. Regardless, the transition of sound between channels are kept clean, clear and smooth.

When it comes to its SEPARATION LEVEL, on top of having a good stage-dimension. The background is pitch-black. There is hardly any low noise that could taint the blackness of its background. The perks being the separated elements will have a clearer cut and spaces between them. On busier tracks, each element of sound maintained its separated borders with great consistency. The effect can be enhanced when using a well-mastered tracks.

DETAIL RETRIVAL may not be class-leading, but it is never lacking by today's standard. And more importantly, the macro & micro detail is presented without forced to ensure a natural sound reproduction.

It has a good DYNAMIC-RANGE. It can convey from soft whispers to loud, powerful crescendos rather accurately.

When it comes to TONE and TIMBRE, it has got to be one the more natural ESS SABRE DAC chip implementation in its class. This time round, Kinera/Celest managed to tune this chip ES9039Q2M to sound more analogue than digital-like which is quite the feat.

The device is WELL-BUILT. It is small, lightweight and durable for portable usage.

The DRIVING POWER is plentiful. The AMP on both SE and BAL is more than enough for most IEMs but might struggle on more demanding headphones. The power delivery is HISS-FREE with zero of CLIPPING NOISE when changing tracks.

The POWER-DRAW is quite efficient. Depending on your phone's battery capacity, It can plays your music for more than 12 hours on High-Gain.

As for HEAT-MANAGEMENT, it is average. Like most dongle, it is going to get warmish after some time. But not blazing hot.

Speaking of FEATURES, it does offer an independent volume control. The increment of volume per steps is not many but it is manageable for average IEM usage. The output has 2 mode which is low-gain and high-gain. It covers most the basic features. It is very easy to operate. I just wish it had a digital app with added filters to improve its tuning versatility. And there is no TFT or LED screen to peek on the mode or volume of you're in. At the very least it is very easy operate.

As for SYNERGY, it is safe to say that it pairs well with nearly everything on the market due to its neutral natural sound. The connected gears will sound closer to its intended tuning.

For about 93USD PRICETAG, in terms of features, it is slightly behind it competitors. But sonically, it is a solid performer.

◤FINAL THOUGHTS◢
Recently, Kinera/Celest has been on roll on releasing budget product. And too many it didn't miss. I am happy to say that, with the CD-20, it delivers an impressive sound quality for its price-point. I have never been a fan of an ESS DAC chips. They tend to sound more digital-like which comes at the expense of the naturalness of its timbre. And to my surprise, it not so the case with the CD-20, which makes it one of my favourite ESS SABRE DAC implementations on dongles to date. Hopefully, they can release a CS or AKM based dongle in the not-too-distant future.

[SOUND QUALITY 8/10 VALUE: 8/10] [NEUTRAL with a slight bass-boost]

KIWI EARS KE4

The META of Low Contrast Sound.

Pros:
- Mid/Vocal-centric tuning.
- Smooth treble response
- Spacious head-stage.
- Laid-back, smooth experience.
- Well-built, light and comfortable to wear.

Cons:
- Picky on source.
- Bass quality could be better.
- Treble could use with more bite.
- Detail-retrieval is not its forte.
- No 4.4 BAL cable option.

[MY PERSONAL HEAD-FI GRADING]
1 ★ - Appalling! please avoid this! (1-3/10)
2 ★★ Subpar offering, there are better options out there! (4-5/10)
3 ★★★ Decent with some caveats! Not a bad pick! (6-7/10)
4 ★★★★ Not perfect but solid choice ! This should be in your shortlist. A nice addition to your collection. (8-9/10)
5 ★★★★★ One the best in class! You should go right ahead & buy one! A must have! (10/10)

KIWI EARS KE4 4 ★★★★

▓▒░ SOUND-SIGNATURE ░▒▓

It has a laid-back, low-contrast sound. The bass, mid-range/vocal and treble sounds almost equally as loud/forward. The mid-range has ever so slightly better focus in the mix. The bass presence is not much while the treble extension is well-extended. Depending on pairings, it can go from neutral to neutral-bright.

▓▒░ PRE-BURN IN EXPERIENCE ░▒▓
For the 1st minute, the bass sounds a tad too boomy while the treble is rather sharp and hazy. And the vocals sounded dry and a tad hasher on transient. After 200 hours of running in, it sounds way more musical.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- Oddly enough, the perceived bass is alot less than the measurement would suggest. Multiple ear-tips has been swapped but the result is quite consistent. There is not much quantity to be squeezed out.

- The sub-bass presence is expectedly mild. The rumbling sensation is there but it is not very atmospheric. It just fades in and out very swiftly without leaving much trace behind. Sub-bass kick has a softer edge to it, lacking that tactile boom that we love.

- Bass distortion element is not the clearest. Bass-drop and ghetto bass replay are acceptable.

- Mid to upper bass presence is more or less the same. The tempo is perhaps just as fast, but the attack it carries is seemingly more impactful. It sounds slightly thicker and hits deeper in comparison to the subs, making punch and slam on percussions more rewarding to listen to.

- Overall, the bassline performance may not be the best for it's price-point. When it comes to bass quality, it could be better. It just falls short in terms of dynamics, detailing and control just a touch.

▓▒░ MID-RANGE /VOCAL ░▒▓

- It does stands out as a more mid-centric set. In a sense that you'll hear vocals and instrument that lives within more prominently.

- The added brilliance coming from the highs, gives its vocal a good level of transparency and clarity. The voice has this crispy and airy texture to them which is good for monitoring purposes.

- Both male and female seems to deliver nigh equal level of performance on stage. They don't seem to overpower each other that much on duet. The intonation of the voice is good. It has adequate amount of energy from low to upper-reach of the voice-range. There is no such thing as shoutiness or graininess on vocal transient, that could affect its refinement.

- This brings it to the downside. On some occasion, the low contrast pinna-gain combined with that enhanced treble, do come at the expense of vocals sounded leaner and sharper than they should. If and only the lower-harmonics could provide enough warmth and body, the mid-range wouldn't lose its euphony that much.

- Which means, male vocal can come across a tad thinner or too sharp and too airy on transient. Meanwhile female vocal could use with abit more energy up top to sound livelier.

- Instrument attack on piano, guitar, flute, strings are on the blunt side. Again, due to its tonality, they can sound rather flat, lacking note weight and fundamental body.

- To my ears, the overall timbre of the mid-range still come across as being natural. And despite my criticisms, I still think that it is one of the better mid-centric hybrids in its price-range.

▓▒░ TREBLE/HIGHS ░▒▓

- The treble delivery has good amount brilliance and air extension which gives openness to the stage. Its response fairly even and smooth. It’s got none of that unwanted resonance with minimal peaks and troughs. Sibilance control is good with almost zero grain issue is heard.

- If I were to nit-pick, the treble though sounded crispy, it is not that crunchy. The attack just lacking a touch of bite. The note-hits are on the light-side. As a result, treble elements can sound less define, lacking contrast that it needs.

- One important thing to note, on brighter pairings, those tizzy sensation that comes from the mid to upper treble region can be distracting. It is even more apparent when the tracks have constant hi-hats and cymbals or constant electronic zinging, buzzing and rattling. Those elements will tend to bleed or mask onto the mid-range, making vocals sound unpleasant. As a result, on highly energetic treble music, it can get quite fatiguing which can be a major deal-breaker to those treble-sensitive folks. Oddly enough, E-guitar elements played just fine regardless.

- If you're facing one of these issues, please do check your source which is worth mentioning.

- In short, the treble can be on the brighter side for some, and it is not the most well-define treble in its class. Having said that, with the right synergy, it can sound quite pleasant.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The STAGE sounds rather open and spacious. It is quite wide, and the headroom is surprisingly tall. And the depth is pretty good too. Vocal placement is well-centralized without being too forward on the stage, while instruments and background elements are nicely placed as it should.

- IMAGING PROWESS is decent by todays standard. The transition of sound between channel is done smoothly without stuttering or jittering. Sound projection though accurate, are not the sharpest in its competitors.

- It's LAYERING AND SEPARATION is pretty good for a low-contrast sound. Yes, the background is not pitch black and because of that, the separated elements doesn't have the clearest of cut. But thanks to the stage dimension, the gap between each element of sound is more than ample. Which mean compression and congestion issue is not going to be an issue. More importantly, the separation level is kept consistent throughout the test even under heavy load.

- RESOLUTION wise, it is average. For its price-point, any planar could potentially out-performed it in terms of micro and macro details. But in all fairness, it is not severely lacking.

- Out for the box, due to its tuning, it is never going to be a DYNAMIC set. The overall attack is on the compress side making elements of loud and soft less distinguishable.

- As for its TONE AND TIMBRE, to my ears, it is not the most accurate but in terms of naturalness, it doesn't sound too digital-like. Overall, the notes just lack that sense of body and the element of reverb to sound more realistic. It is more forgiving on vocal playback but on instruments replay, it is quite noticeable.

- Talk about VOLUME SCALLING. Again, it is average. Sure, with the right synergy, you could crank it up to mid-high volume. Still, dialing it up too high, the bass and treble can sound abit much, overpowering the vocals.

- As for the DRIVER QUALITY. Its more than capable to achieve its goal. There is no driver-flex issue and it is not that hard to drive to listenable volume but they do perform better with greater AMP.

✧ ════ •POTENTIAL SYNERGY TWEAKS• ════ ✧

- EARTIPS : I’d say, ditch the stock eartips. As it tends to emphasize the treble zings and reduce the bass presence even more. I just stick with SPINFIT CP100, it helps with the bass body and vocal intimacy.

- DAC/AMP: As mentioned on the "treble" section, It is a tricky one. If the DAC doesn't have a good bass control, the KE-4 lows will start to sound loose and boomy. On the other hand, if the DAC has a greater treble emphasis, those constant hi-hats and cymbals or electronics will start to get distracting. So, it's about finding the right synergy to compensate its bass quality and treble presence. In my case, I just stick with Tanchjim SPACE on “Low-Latency, Slow-Decent” mode. It doesn't sound too bright or sharp with a slight low-end warmth emphasis. The Ibasso DC07PRO (Slow-Roll-off Mode) is another neutral-warmish source that pairs well with the KE-4. Its sounds fuller, smoother with abit more air up-top.

✧ ════ •BUILD/ PACKAGING/COMFORT• ════ ✧
- The build quality is more than good enough. The design is very minimalist with cool looking faceplate.

- For 200$ USD the packaging could be better. There is no 4.4 BAL option which questionable in today's market. It provides 3 sets of Kiwi Ears Flex Silicone eartips, sizes from S to L size, 2 sets of replaceable filters with decent small carrying case. The overall unboxing experience is pretty mundane.

- Comfit wise, with right ear-tips, it is comfortable enough for long sessions. Smaller ears might want to use a smaller set of ear-tips to get the best fit.

QUICK HEAD-2-HEAD

vs Tanchim PRISM x Yongse Treasure 4.4 BAL x Spinfit CP100 (M)
This may not be a fair comparison when it comes to pricing but it is the only 1-DD-2BA hybrid that I have to compare with..

PRISM is definitely bassier and more sub-bass oriented. The bass reproduction sounds more natural and realistic. When it comes to dynamic, tactile, decay, pressure, sustain and layering, it is leagues above.

KE4 is the most mid-centric of the two. The mid-range/vocals will always be the highlight. But for some reason, the PRISM is better at capturing the emotional of vocals. The intonation to the voice is more accurate. The notes are heftier with greater presence of reverb.

KE4 seems to have better treble extension. It sounds air-er and brighter from mid to upper treble. But the PRISM offers more bite. High frequency percussions like hi-hats and cymbals have a metallic shimmer while electronic zings have a nicer ring to them.

KE-4 staging sounds more open. The width is nigh identical, but the headroom is more generous with slightly better depth. The PRISM will sound more intimate and holographic by comparison.

Imaging prowess on the PRISM is a notch higher. Its more accurate and much sharper when it comes to sound projection between channels.

When it comes to separation level, the border between each element of sound on the PRISM has a clearer cut thanks to its imaging ability and darker background but on a busier tracks, the KE-4 is more consistent, whereas the PRISM tend to struggle depending on mastering quality.

PRISM has slightly upper hand when it comes to retrieving micro and macro detail.

Overall timbral accuracy goes to PRISM. The attack is wider, the decay rate is more precise, it has better note-weight and the presence of reverb is not missing that much. The end-to-end of notes sounded more complete. Instrument just sounds more realistic by comparison.

The build quality on the PRISM is next level. It is very jewellery-like. It is cold to the touch with exceptional craftsmanship. But when it comes to comfort, the KE-4 might better overall. It is lighter and with its semi-custom resin style makes its more versatile for most ears.

When it comes to value, this 3 years old PRISM does not come cheap. And performance wise, the KE-4 just offers better value.

" The PRISM is definitely more fun, and it is beautifully made. But it is very expensive. However, if vocals is your priority and you appreciate a more laid-back experience, then the KE-4 is more than enough."

◤FINAL THOUGHTS◢
The KE-4 that is not going to suit everyone. Just getting the right synergy alone is quite tricky because this sort of low-contrast tuning is very easily off-set by the source tuning. But once you get it right, you will start to see why people likes it. To the contrary, you can understand why people hate it. I was lucky enough to assess the KE-4 long enough to find the right synergy, just to experience its potential. If you're expecting a dynamic bass and engaging treble response, the KE-4 is not going to be it. But if your library consists of vocal content first, then the KE-4 might be just for you. As for myself, it does grow on me the longer I listen to it which is a good sign.

KINERA CELEST IGNITEX BEAST 4½★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
The tuning profile of the IgniteX lies in the form of a mild-v shaped sound. It has greater emphasis on the upper-mids with an elevated mid-treble zing. The bass has a slight boost, but it is a sub-bass biased. It is not a bass-head set, it is by no means a treble set and it is not a vocal specialist set either which makes its one of the more all-rounders set in its class.

▓▒░ PRE-BURN IN EXPERIENCE ░▒▓
It sounds great out of the box. Perhaps after a week of usage, the bass gets tighter and the treble seems a smidge clearer.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
With just a slight bass-boost, it keeps the low-end clean without overpowering the upper registry. Overall, the low-end is rather assertive but it is never domineering. It is well-controlled and smoothly textured.

The low-end extension is not much. The sub-bass attack is rather polite with a moderately fast decay rate. As a result, those rumbling, droning and booming sensation may not be the most satisfying to listen. It’s there but there is no pressure built up to it to keep it atmospheric. Thankfully, the sub-bass kicks are punchy giving a satisfactory level of tactile boom.

Ghetto bass elements have good bound and rebound rate while bass-drop is kept clean and clear. As for the bass distortion elements, they are well retrieved.

On paper, the mid-bass is seemingly less but for some reason they sound more impactful than the subs. They have good amplitude of attack and hit quite deep to leave an impression. Instrument like drum hits or percussions seems to hit, slam, punch and kick harder than expected.
The notes are nicely weighted and offers a more precise decay unlike the sub-bass which tend to linger a tad longer than it should on a fast bass tracks. Thankfully there is no spill over of mid-bass onto the lower mid-range which can be a good or bad thing depending on your library.

All being said, the bass performance is definitely one of its strength. The layering and detailing is very good for the price. It offers a good balance between quality and quantity but ultimately, it is by no means for bass-head.

▓▒░ MID-RANGE /VOCAL ░▒▓
Overall, the mid-range/vocal took a more neutral approach in its positioning, it is neither too forward nor recessed.

Both male and female seems to offer equal level of performance on stage. They sound smooth, clean and clear. There hasn't been any shouty, graininess or dryness situation as far as the assessment goes. And that’s about it.

Unfortunately, the vocal rendition could use some work. The vocal texturing is definitely on the smooth side. It is not very good at retrieving those micro-nuances on those voices. The elements of breath, hoarse or coarse don't really standout that much.

It would have been better if the vocals fundamental body were denser. There are times when there is a slight hollowness to the voice especially with male vocals.

The vocal can sound a tad too safe for some, lacking that crescendo on transient. It sounds as if the singers are holding back their emotions.

On top of that, the vocal reverb is not that prominent which is not ideal on an acoustic track.

The same can be said with its instrument replay. The attack definition are just lacking (piano, violin, strings, guitar, flute).

At the very least, despite the nit-picks, they still sound natural in its own way. It's just that from a vocal attribute standpoint, it is missing some of that finesse that can makes vocal and instrument sound great.

▓▒░ TREBLE/HIGHS ░▒▓
The treble extension is quite good. It doesn't sound too dark nor too bright. The response is fairly smooth.

There is no unwanted resonance that could irks your experience. There is a good amount of crispiness, brightness and clarity to them. They sounded clean and clear most of the time. None of that graininess or haziness that would normally associate with a BA driver.

The treble elements are mostly well laid-out without sounding forced or too aggressive in its demeanour.

However, it is not all perfect. On some occasions, that mid-treble emphasis can make highs region percussions like drum-hits can sound a tad peaky. Noticeably, on higher volumes.

And if I were to nitpicks, constant hi-hats and cymbals have a more rounded-edge to them and the shimmering effect is not quite there on the overrun. As for e-guitars, it could use with abit more bite for added grunt. Meanwhile when it comes to electronics or synthetic noise, it rings, zings, buzzes and rattles just fine .

Regardless, this level of treble performance may not be the most detailed but its level of refinement carries this set, giving the quality it needs.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- As for the STAGE, it is very wide, good depth but there is not much height to the dimension. The vocals are dead-centred surrounded by images of instruments.

- When it comes to its IMAGING PROWESS, is quite impressive. The SOUND LOCALIZATION from left to right is not the most razor sharp but it is very accurate. Thanks to provided depth, front to back layering is not bad either.

- SEPARATION level is one of its strong points. Although the gap between each element of sound isn’t generous. The borders of separated elements are highly maintained with great consistent thru-out the test.

- Having a clear and clean sound does help with its clarity. DETAIL-RETRIEVAL never seems to be lacking, providing your music with sufficient amount of macro and micro detail.

- TIMBRE wise, vocals and instrument are far from sounding unnatural. But it is not the most accurate I've heard. There are times when the vocals and instrument sounds abit weightless/lack body and the texturing could use with more bite or attack definition. The same can be said with instrument like piano, guitar plucks, violin or strings, they can sound abit light and smoothed over. Which is good for laid-back sessions but not so much if you're looking for realism. The other aspect that is affecting its timbre accuracy is probably the overtone or the reverberation level. I find the trailing of reverb is missing a touch on vocals and instrument. Having said that, being hybrid, these issues are quite common. At the very least, there is no annoying BA grains or sharpness is heard.

- For a safe tuning like this one, the DYNAMIC RANGE is not going to be that wide but elements of loud and soft can still be distinguish when your ears are focused.

- It does VOLUME SCALING quite well. In fact, you really need to dial up the volume to get the most out of it. Otherwise, it can sound too relax and get bored pretty quickly.

- As for the DRIVER QUALITY. Its more than capable to achieve its goal. There is no driver-flex issue, and it is not that hard to drive to listenable volume.

✧ ════ •POTENTIAL SYNERGY TWEAKS• ════ ✧
- EARTIPS: I’d recommend using the SPINFIT CP100 if you want to improve the bass tactile and mid-range body and intimacy.

- DAC/AMP: I’d suggest using something brighter, cleaner, less coloured and more technical source like the Tanchjim SPACE, it does help to improve its technical aspect. But it does works well with a neutral-warm signature like the CELEST CD-20 or XDUOO LINK2BAL. It helps the lower-mids to sound fuller and richer while taming down those mid-treble energy.

✧ ════ •BUILD/ PACKAGING/COMFORT• ════ ✧
- Like most Kineras/Celest, its built quality is top-notch. It is lightweight, not too big and beautifully finished.

- Its packaging is small and reasonable for the price. There is a mic option as well, but it would be great if can they provide it with a 4.4 BAL cable option. While the stock cable could be better as they are very memory prone and too thin.

- Comfort wise, it has this semi-custom-like resin shell which really helps in its ear-gonomics. There is not protruding cleave or bulge that can cause discomfort.

SHORT COMPARISON

vs CELEST WYVERN QING (Stock)

- IgniteX has tighter bass control. Punchier and hit deeper.
- Qing has greater sub-bass pressure and sustain. And boomier
- Qing slightly better at capturing reverb on vocals and instruments.
- Qing has fuller and richer mid-range vocals.
- Qing is vocals sounds slightly more emotional/euphonic.
- IgniteX has slightly better micro-contrast on vocals.
- IgniteX has airier treble response. More sparkling up top.
- Qing is darker but void of spiciness or hotness.
- IgniteX has better treble-detail.
- IgniteX has wider and deeper stage while Qing is slightly taller.
- IgniteX stereo-imaging is sharper and more accurate.
- IgniteX separation prowess is a notch better.
- IgniteX detail retrieval is smidge better.
- IgniteX clarity is a notch higher.
- Qing has greater advantage on capturing music ambience.
- Qing timbre sounds ever so slightly more natural. It has better note weight and decay.
- Both are equally easy to drive.
- Both are equally as comfortable to wear.
- IgniteX is prettier and better built.

" When it comes to technical performance, the IgniteX is clearly a notch above the Qing. However, the Qing still has the upper hand ever so slightly in terms of tone and timbre. It sounds a tad more natural and euphonic to my ears. In other words, the IgniteX is not the direct upgrade to the Qing. They sounded different enough to complement each other. If you already have the Qing, and you’re looking for something different I’d definitely recommend you try and get the IgniteX for a different set of flavor."

◤FINAL THOUGHTS◢
Celest has managed to cook something solid yet again. It is truly shocking to see how far a budget segment has grown today. If I were to get similar hybrid setup from 2-3 years ago, we would probably have to pay around 200-300$ for this level of sound quality and refinement. And most of the flaws are mostly nit-picks.
Yes, it is not perfect. But what you get for the price is nothing short of impressive. And bear in mind I've been gauging it by using sets that cost way higher than it does which says alot. I can definitely see myself recommending this set to my fellow audiophiles in the future that wants a laid-back sound that isn't too boring without breaking the wallet.

CELEST WYVERN QING 4 ½ ★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
It sounds like a bassy, mild V-shaped that plays somewhere along the lines of Harman tuning.
The bassline is noticeably sub-bass oriented. The mid-range/vocal is slightly recessed with the treble response falls on the darker side of the spectrum.

▓▒░ PRE-BURN EXPERIENCE ░▒▓
On my 1st hour of listening to the Qing, the bass sounded rather loose and the attack on it was quite limp. There is a consistent layer of grain on vocal transient regardless of tracks. As for the highs, it exhibits a hint of hotness on the lower part of treble region. But after about 200 hours of high volume of burn-in process, those mentioned flaws are seemingly less.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
The bassline is definitely boosted but it is not too overpowering to a point it muddies up the upper registry. It is more of a boomy and rumbly bass rather than a thumpy and snappy bass.

The sub-bass shows a greater dominance in the lows. The subs give off decent extension, pressure and sustain. Those rumbling, humming, droning and booming effects are well captured. It may not provide be the most atmospheric or impactful playback, but it is more than acceptable. The sub-bass kick is surprisingly addicting. It is tight and punchy while elements of bass drop and distortion are heard clean and clear. Its ghetto bass replay is not the bounciest I've heard, but it is never sounded too stiff. While, for a resin shell those reverb and overtone traits are well-perceived, thanks to its bassline having a neutral rate of decay that is not too fast upon fading.

The mid-bass presence is seemingly less, especially on the upper-bass region but it is not severely lacking. Despite lacking that sense of fullness and body, the attack on those percussion instrument that lies in this region such bass guitar, kick drums, drum-strike still carries good amount amplitude and weight behind them. So, they never come across as being muffled or blunted, just not as forward in the mix which is good.

Generally, for a bassy tuning, it is well-sorted. It rich, fast, clean enough and well-behaved for most genres. It is rumbly and punchy when it needs to. Never is sluggish. Its bassline is probably one its key strenght. For as long as you don’t expect a powerful, impactful and highly detailed bass quality, it will be more than enjoyable for most listeners which I did.

▓▒░ MID-RANGE /VOCAL ░▒▓
As expected, it is not for people who prefer an intimate or immersive vocal presentation. But on the other hand, I find the vocal and instrument placement just about right. It is well-centred, not too forward, nor it is too rearward. More importantly the vocal is well-separated from the rest of the instrument for most of the time.

Vocal and instrument are smoothly textured but decently nuanced. They never sounded dry or harsh. And that pre-burn vocal grain has been brought to lesser degree. They sounds more forgiving as we speak.

As for the downside? Indeed, there isn’t generous amount of warmth and body to fill the lower-mid-range. As a result, chesty vocals (baritones), cellos, brass instrument, organ that lives in this region can sound thinner or further back in the mix. While it is not an issue with female vocals, those higher octave vocalists seem to long for that last bit of extension up in their voice-range. They don't seem to shout or scream enough when they need to (Unless the songs is very shouty or screamy, then you might not feel it). It’s a shame because their initial energy was there just to get cut-off by that low-to-mid treble energy dip.

Truthfully speaking, there is no major flaws with its mid-range presentation, especially when considering its tuning approach. Yes, it may not be the most well-filled out mid-range (Richness/Fullness). Yes, it is not the most transparent mid-range either. Yes, it is not most the engaging nor emotional mid-range among its peers. However, to my ears, it hits just the right balance between euphony and clarity. And more importantly, despite its quirkiness, the vocals sounded clear, smooth, natural yet pleasant. And the same true can be said with its instrument replay such as pianos, strings, violins and guitars. Despite having a smoother note-edge, they have adequate amount of body and note-weight to maintain good natural timbre.

▓▒░ TREBLE/HIGHS ░▒▓
The treble performance is probably its weakest point. It is not the most well-extended nor it is the most evenly response treble. It barely has enough brilliance to cut through its bassline presence. If bright, airy, sparkling treble is what you’re looking for, please look elsewhere. However, from a dark treble perspective, it is not bad at all.

Treble elements are still present though not as prominent as one might like. Instruments like constant hi-hats or cymbal crush came across as inoffensive with precise decay and timbre. E-guitars has just about enough grunt while electronics zings and shimmers have nice ring to them. They may not sound as crisps as some would prefer, but at the very least they don’t sound too weightless. Treble definition may not be the sharpest but for the tier it’s at, it is forgivable.

Refinement wise, it’s decent. There is no grain, haze, distortion except on higher volume, those treble peaks will show up eventually. Overall, it’s smooth enough for most low-to-mid volume playback.

Despite my criticism, the treble response is more than good enough to carry this set which is a good sign.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The STAGE-DIMENSION is quite ordinary. It plays more width than height with decent sense of depth. In other words, it is not that expansive but is not too cramp either.

- The SPATIAL CUES/ INSTRUMENT PLACEMENT is mostly accurate, but it is not pin-point sharp. Thanks to its darker treble response. Its left-to-right imaging was good but as for the front-to-back is decent at best

- It’s LAYERING AND SEPARATION is fine on less complex tracks. But on a busier track, it tends to struggle especially on those rock and metal genres. Anything that has multiple layers of bass and treble elements playing together with face some congestion issue. Using a well mastered tracks do helps but it can only go so far.

- The overall RESOLUTION AND DETAIL RETRIVIAL is just average for this tier. Macro-detail is good but micro-detail is wise is not the best.

- Like most single dynamic drivers, they always have this naturalness to its TONE AND TIMBRE. And this one is no exceptional. The notes are nicely weighted. They possessed decent amount of body. And the decay is never unnatural. Though, the transient could use with a wider attack for added impact.

- It’s DYNAMIC-RANGE is not that big. Partly because the treble is lacking that extension up top which takes away its ability to discern between the element loud and soft.

- The VOLUME SCALING is not its forte. It is only good up until mid-volume. Any higher, the bass will sound too boomy and the treble peaks will start to become more apparent.

- As for the DRIVER QUALITY. Its more than capable to achieve its goal. There is no driver-flex issue and it is not that hard to drive to listenable volume.

✧ ════ •POTENTIAL SYNERGY TWEAKS• ════ ✧
- EARTIPS : I’d say, ditch the stock eartips. It does open up the treble but at the expense of low-end and mid-range body. I’d recommend the SPINFIT CP100 if you want to improve the bass tactile and mid-range body and intimacy. Or you can go with PENTACONN PTM02 COREIR (AL ALLOY) eartips if wan to improve the treble definition and decrease the bass presence. If you want something in between you could try DIVINUS VELVET (narrow-bore) eartips.

- DAC/AMP: I’d recommend using something brighter, cleaner, less coloured and more technical source like the Tanchjim SPACE as it really helps to tightening it’s bass response while brightening up its treble. By using something warmer could lead it to sound too bassy, affecting its overall balance.

✧ ════ •BUILD/ PACKAGING/COMFORT• ════ ✧
- Like most Kineras/Celest, its built quality is top-notch. It is lightweight, not too big and beautifully finished.

- Its packaging is small and reasonable for the price. There is a mic option as well, but it would be great if can they provide it with a 4.4 BAL cable option. While the stock cable could be better as they are very memory prone and too thin.

- Comfort wise, it has this semi-custom-like resin shell which really helps in its ear-gonomics. There is not protruding cleave or bulge that can cause discomfort.

◤FINAL THOUGHTS◢
I’ve been using the Wyvern Qing for about a week now. And I have to say that I enjoy using it more than I’d initially thought. From a technical standpoint, it can never outclass anything higher up in the hierarchy. But what it does best is providing audiophiles with a musical experience for a fraction of the price. I’ve own multiple sets that cost way higher than this one. But with the Wyvern Qing, I don’t find myself lacking that much in terms of enjoyment. I could definitely see myself recommending this set to someone that shares similar music preference but only have 30 bucks to spent.

I/O VOLARE 4 ★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
The sound it makes is the sort of tune you’d get from a mildly, well-balance V-shaped. The bass is slightly emphasised. The treble is enhanced while the mid-range is somewhat pushed-back a little.
There is a hint of warmish tonality carries from the lows with a tasteful level brilliance ascending from the highs. All of that adds up, creating a natural replay that is laid-back, smooth and pleasant to the ears.

▓▒░ BASS/LOW-END░▒▓
- The low-end of the Volare has this genteel demeanour to it. The elevated bass is done without overpowering the upper-reach, quite a bit less than most measurements would suggest. It has a gentle, warmish tonality which spilled ever so slightly onto the lower-mid-range, giving an organic touch on vocal and instrument replay.

- The sub-bass extension is adequate for most genres. It’s rumbling sensation could use with better texture and higher pressure. Meanwhile, kick-drum delivery is quite soft which detract some of the engagement that you’d normally get from a proper tactile boom.

- Mid to upper bass presence is brought to a lesser degree. Like the sub-bass, the mid-bass too carry the very same behaviour which is soft on the attack with neutral (longish) decay. But it’s got enough thickness which helps with its mid-upper bass sturdiness. Having said that, it doesn’t leave you with a satisfying punch, slam or thump. A hardcore bass-head will definitely be yearning for more oomph.

- Alas, the bass performance on the Volare is far from terrible. It should be good enough for most listeners.

▓▒░ MID-RANGE /VOCAL ░▒▓
- The Volare is not meant for an intimate vocal lover. Yes, as the tuning suggest, the mid-range is slightly pushed back and no lesser.
- Worry not, the vocal does not come across sounding too thin or dry or overly recessed. Most vocal lovers can still appreciate its mid-range presentation.

- It does sacrifice a bit of that transparency and clarity for musicality. The extra warmth reaching from the lows makes the vocals sounded smooth, rich, sweet and pleasing to the ears. They will never sound harsh regardless of tracks.

- The female vocals have proper energy without sounding shouty.

- As for the downside, chesty vocals (baritones), cellos, brass instrument, organ that lives on the lower region of the mids. can sound abit further back/thinner side.

- Depending on tracks, there is a smidge of micro-grain or haze on vocal transient which can smear some of the vocal clarity.

- Sibilance control is borderline acceptable as there is hint of bearable sibilance on both male and female vocals.

- When it comes to instrument like piano, guitar, violin or strings, the attack can sound abit smooth-out. They don’t sound as crispy or as impactful as I’d like. On instrumental tracks, that is not welcome.

▓▒░ TREBLE/HIGHS ░▒▓
- The treble is very well extended without overbearing brightness. It rolls off nicely with plentiful amount of air presence. It is a well-filled out treble.
- It response fairly smooth without any unwanted resonance such ay peaky-ness, hotness or sharpness.
- The ESTs driver on the Volare is nothing short of potent. It manages to define its treble elements naturally without forced. As a result, listeners are rewarded slightly above average level of treble detail.
- However it does not perform without a flaw. Firstly, the treble layout isn’t the cleanest. On some tracks It, it can exhibit this subtle layer of micro-grain or haze.
- When it comes to instrument like hi-hats and cymbals, again, the attack has a more rounded edge to them, though the decay is precise and smooth. Meanwhile, electronics may lack abit of bite upon zinging, buzzing or shimmering which takes away some of the excitement.
- Having said that, most of nit-picks are minor. It does not bring detriment to your experience. In fact, majority of the people will definitely rejoice of what the treble has to offer.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The overall STAGE-PRESENTATION is above par. It sounds open and spacious. It gives off more width than height with generous depth to the stage.

- IMAGING PROWESS is superb. Instrument & vocal placement is accurate and well-focused. There is no jittering or stuttering. Everything just flows between channel with grace.

- LAYERING AND SEPARATION is spot-on. Regardless of tracks, separated elements remains in its borders of sound consistently without any sign of congestion or compression. Everything has their own little spot.

- It's got great RESOLUTION with excellent MICRO-DETAIL. Definitely one of the tops among its peers on its price-point.

- TONE AND TIMBRE wise, it does a good job in staying natural. If I were to nit-pick, the overall transient could use with greater attack amplitude. The smoothing effect on note-hits takes-away some of the realism on replay. There are times when you’ll hear it but you don’t necessarily feel it.

- For a safe well-balance tuning, the DYNAMIC-RANGE of the Volare is solid. The elements of loud and soft is well discerned within the mix which makes it more engaging to listen to than some of its competitors that follows similar sort of tuning.

- VOLUME SCALING. The Volare is not great for a low-volume listening. It can sound too smooth and the micro-detail is not that prominent. It is best to listen to mid-volume loudness for optimum performance. If it is too loud, the peaks will start to appears.

- Speaking of DRIVER/SETUP, it is definitely one of the best. They use good quality driver with proper implementation from lows to highs. For a 9 driver setups, the coherency level is exceptional.
Yes, there is a hint of timbre-contrast when transitioning from the bass to mid-range and treble. The upper-registry just sound a tad faster and lighter while the lows sound a tad slower. Still, it is very minimal. At the very least, it is free from driver-flex or pressure-build up issue.

- BUILD/COMFORT, the resin shell is well built. The silvery metallic accentuation makes it such a beautiful shell. The shell is not that big. It should fit most people ears like glove.

- PRICE: PERFORMANCE is great. From unboxing experience to sound-quality, it is top-tier. Not many CHIFI-products does as well as this.

So far It performs quite well for what it's trying to be. But how does it stacks against some of the well-known tribrids?

Here's a simplified HEAD-2-HEAD
LETSHUOER EJ07M x HAKUGEI SKYRIM x TANGZU SANCAI BALANCE (M) vs
IO VOLARE x TANGZU SANCAI BALANCE (M) vs
ALPHA OMEGA x KBEAR WIDE 8C GRAPHENE x TANGZU SANCAI BALANCE (S)

<BASS>
● Bass-Shelf : RA > V > EJ
● Tonality (Warm-Neutral-Dry) : V (WN) > RA (WM) > EJ (N)
● Subs Extension/Quantity: RA > EJ > V
● Subs Attack : RA > EJ > V
- RA has the highest pressure, EJ is close behind. V softest abit loose abit a muffle.
● Sub-bass kick: RA = dung-dung > EJ = thung-thung > V = bhung-bhung.
● Sub-bass detail/texture: EJ > RA > V
- Although, the EJ don’t have the same volume as the RA, EJ subs have better clarity and detail. V rumbling detail & texture is the weakest.
● Ghetto Bass (elasticity/decay rate): EJ > RA > V
- The EJ is bounciest.
● Bass Distortion: EJ > RA > V
- The EJ’s has the clearest bass distortion.
● Bass Drop: EJ > RA > EJ.
● Mid-bass Presence: RA > V > EJ
● Mid-bass Attack (Punch/Slam/Thud): V > EJ > RA,
- The EJ hit faster and slightly deeper than RA but RA hits bigger, thicker and heavier. Meanwhile V is a mixture of the 2, it carries similar width and depth in terms of impact of the RA but slightly slower than EJ and RA.
● Mid-bass detail/clarity: EJ > V > RA
- The EJ mid-bass is cleaner and clearer than RA but RA has greater substance. V sits in between EJ and RA with a hint of more warmth than the other 2.

<MID-RANGE/VOCAL>
● Mid-Range/Vocal Intimacy = EJ > V > RA.
- The EJ has the most forward, biggest image resolution of the 3.
● Male Vocal: RA > EJ > V
- The RA just hits the right balance in terms of note-weight, clarity and energy. The EJ lacks abit of that density and overtone. On V, it can sound push-back or thinner at times.
● Female Vocal: EJ > V > RA
- The EJ performs at higher octave while the RA is better for lower-harmonic female. V is in between. Overall, EJ performs better since it has no sibilance issue, greatest clarity with decent timbre.
● Voice Range: V > RA > EJ
- The V & RA seems to have slightly higher extension. The EJ can sound a tad too safe and boring lacking that of crescendo on transient.
● Transparency: EJ > V > RA
- Nuances like breath, instruments hits can be heard a hair clearer on EJ.
● Clarity: EJ > RA > V
- Sometimes V vocals have a hint of haze/grain and the background is not as pitch-black vs the EJ or RA. The EJ is super clean by comparison.
● Tonality (Warm>Neural>Bright): V(W-N) >RA(W-N) >EJ (N)
- The V has more apparent warmth to the voice/instrument. The RA slightly less. The EJ is almost uncoloured.
● Tone & Timbre: RA = V > EJ.
- Depending on tracks the RA and V can out-performed each other, their mid-range somewhat sounds more natural and whereas EJ can sound too clean and neutral.
● Transient/Attack: RA > EJ > V
- The RA seems to have heftier note-weight. The EJ is fast but less impactful. The attack on V is the softest. These traits will become most apparent on instrumental replay such as pianos/guitars/violins/strings.
● Airiness: V > EJ > RA.
- The V sounds abit more airy-er thanks to its treble extension.
● Reverb Level: V > RA = EJ.
- Due to longer decay, elements of overtone are better on The V. While EJ and RA are night equal.
● Sibilance Control: EJ > RA > V.
- The EJ had 0 sibilance issue. The V is the least forgiving here. V has higher tendencies to get sibilance on male than female.
● Shout Control: E J> V > RA.
- The EJ the most anti-shout set of the 3. The V comes in 2nd with borderline control. While with the RA, it can get abit hot on some female vocal but it is never too shouty.

<TREBLE/HIGHS>
● Tonality (Dark->Neutral->Bright): RA (D) > EJ (DN) > V (NB)
- RA treble region is the most veiled here with V is being the brightest, the most sparkling here.
● Air-Extension: V > EJ > RA
- V have the most air presence among the 3. The EJ and RA are closer to each other.
● Evenness: EJ > V > RA
- All of them doesn't sound peaky on low-vol. but once you listen to them louder, the peaks will start to show up. Hence, the result.
● Transparency: V > EJ > RA.
- V has the best transparency here. You do hear abit more twinkly-sparkling detail with the V. But the EJ is close behind while the RA seems to have the lowest-RES here.
● Clarity: EJ > RA > V
- Quite consistently, there is a layer of haze or micro-grain somewhere around the treble region with the V and it sounds busier, RA is seemingly cleaner. While the EJ is simply the clearest and the cleanest.
● Timbre: EJ > < V > RA
- Sometimes the longer decay on V makes constant hi-hats/cymbals to linger longer than it should. RA consistently has the more natural decay with EJ being 2nd. E-guitar replay on V is the most satisfying here with its wider attack and energy it carries. The EJ’s E-guitar is abit muffle by comparison due to softer attack and less weighty. The RA does abit better due to its heftier E-guitar tone. The EJ doesn’t like rock/metal music. But with Saxophones as well as synthetic noise such as electronics zing, shimmer, twinkling, distortion etc, the EJ takes it.

< TECHNICALITIES >

"If you're after for smooth bassy sound, the RA is the best choice here. Despite it's short-coming in technicalities, it is such a pleasant set to listen to. The VOLARE is the most well-balanced here, the better all-rounder and probably the safest pick of the 3, but it is kind of boring, The EJ07 on the other hand sounds the most special here. It has that X-factor that makes audiophiles long after this set. That immersive staging and high level of clarity is truly something else. though, It is not going to be for everybody. But it will my personal pick which is why I owned one."

◤FINAL THOUGHTS◢
Being their very 1st product, the IO has achieved an incredible feat with the Volare. The price performance it offers is nothing short of competent. It can compete very well with older-generation of “trinity tribrid” A.K.A the Moondrop Variation, the Thieaudio Oracles and the Letshuoer EJ07M variant (let alone the original EJ07) which is no easy feat. Even after many years has passed, those trinity-tribrids are highly regards in its price-point even till this day. With the appearance of the IO Volare, you might want to check it out because from a technical stand-point, the Volare can really do a number on those 3. Depending on your preference, you might actually prefer the Volare as well. To me, the Volare is not going be your “END-GAME” set but it can definitely be a “PAUSE-GAME” set for many audiophiles out there.

5 ★★★★★ One the best in class! You should go right ahead & buy one! A must have!

LETSHUOER EJ07 4 ★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
The EJ07 follow suits the likes of diffuse-field (DF) tuning. The overall sound is quite neutral, linear with minimal colouration to the tone. The mid-range will have a frontal image on stage. It is very vocal-centric. There is hint of sub-bass emphasis but not by much. This is a noticeably dips on the treble region which makes the highs seemingly dark. The extension on both-ends is not that high but it is more than adequate for a neutral and natural sound reproduction.

▓▒░ BASS/LOW-END ░▒▓
- The EJ07 is bass-lite set. The bassline is so close to neutral with a hint of warmish coloration to the tone. Both the subs and the mid-bass seems to have rather fast transient with a quick-ish rate of decay. Despite not having the strongest bass presence, the low-end is very well perceived. It is clear, clean and more importantly has good control, void of muddiness and bloat effect.

- The lows have noticeably higher sub-bass emphasis with a decent extension, pressure and sustain. Sadly, the rumbling texture and tactile boom isn’t the sharpest nor the tightest in definition. The sub-bass kick is punchy enough while bass-drop is kept clean and smooth. Ghetto bass replay has sufficient elasticity/re-bound rate which is good.

- The mid-bass somewhat has a linear and flatter response. The attack is fast but soft. Those sensation of kick, punch, slam and thump just missing that authority that it needs, lacking abit of physical impact on replay. It can sound muffle at times. Percussion instrument that lies in this region like bass guitar, kick drums, drum snare are most likely not going to have a satisfying replay.

- All of which contributed to an average level of bass detailing and dynamics which might not impress a true bass-head. The bass reproduction is by no means appalling but it isn't the most appealing to say the least.

▓▒░ MID-RANGE /VOCAL ░▒▓
- The EJ07 was purposely tuned for this. The vocal and instrument that lives in this region will have the biggest image resolution on stage with great level of intimacy and immersion.

- The overall tonality of the vocal is on the neutral side of the spectrum. There is almost no coloration to them. The vocal fundamental body is never lacking. They will always come across sounding lush and full-bodied.

- Energy wise, it is on the safer side, which means they will never sound shouty or honky despite the forwardness it possesses.

- Apparently, the voice still offers an adequate amount micro-contrast but not on a monitoring level. It seems to trade some of the vocal transparency for added smoothness.

- The vocal rendition is just smooth, clean and clear to a point that there is almost zero harshness, grains or edginess.

- The downside is, if you prefer the more crispy, airy, lively vocal performance, you really have to crank the volume few notches higher to bring out the best of vocal texture and engagement. Otherwise, the vocal will sound a tad too smooth and less emotional. For a low-volume listeners, it might be an issue.

- Since is there is not much bass and treble presence, the vocals, especially female vocal can sound a tad too forward in the mix.

- When it comes to vocal intonation, it may lacked that crescendo on vocal transient. it is very good when you're in the mood for relaxing session but it can get bored really quickly when you want to have some fun.

- The same can be said with instrumental like piano, violins, strings, guitars and flute. They seems to have a more rounded edge to the notes. They don't sound distinctive enough.

▓▒░ TREBLE/HIGHS ░▒▓
- For a dark treble response, do not expect it to have a proper top-end extension or you'll be disappointed. If airy, bright and sparkling treble is what you are looking for, you might want to look elsewhere.

- But you will be impressed by the sheer refinement that it can bring. The way those 4 ESTs carry the treble is remarkably smooth. There is barely any harshness, grains or any annoying peaks throughout the test. It is highly capable of taking high volume loudness without distorting it’s treble.

- Even without a high treble energy, but because the clarity is top-notch. those underlying treble elements can still be heard quite well. If you listen carefully, the treble detail is still presence but not upfront.

- Instrument like hi-hats and cymbals will sound less apparent in the mix. Percussions like drum-hits are still well define. The initial hits will have a smoother-edge to them with a precise and natural decay.

- Meanwhile synthetic noise such has electric guitar, electronic zings and shimmer could use with more bite for a crispier response.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The HEAD-STAGING on the EJ is not that grand nor spacious. It has one of the smallest stage dimensions among its peers. What you’ll hear is a very forward vocal placement with instruments wrapping around the vocal closely. Everything will sound more to the fore. Having a multiple of frontal projection at the same time can sound abit too much for your eardrums especially on those chaotic tracks.

- The Left to Right IMAGING between channels is exceptional. It is very accurate and precise. Definitely one its greatest strength. It is holographic and immersive.

- Despite not having an expansive stage, it has very strong sense of LAYERING AND SEPARATION. Most of the time, it was boosted by its high level of clarity and its pitch-black background, giving those separated elements a clear-clean cut. Even in a crowded stage. Be it on poorly or well-mastered tracks, the borders of each element of sound are consistently maintained.

- Its overall RESOLUTION is above average. But when it comes to MICRO-DETAIL, it not the greatest but it is no slouch.

- TONE AND TIMBRE wise, it is not the most organic sounding I've heard. The attack can sound a bit too smooth and light at times. The overall tonality can sound a bit too clean, lacking abit of coloration to sound life-like.

- The DYNAMIC-RANGE on the EJ07 is perhaps one it’s weakness. It lacks a bit of extension on both-end, mainly on treble region. Vocal and instruments could use with wider-attack for added impact. Most of the time the elements of loud and soft doesn't have much contrast. Which makes it not suitable for some genres like instrumental/orchestra or rock and metal.

- Does it SCALE WELL WITH VOLUME? Hell Yes! It is one of the very few IEMs that can scale above medium-high volume without distorting the sound. Mind you, the EJ07 is a very terrible low-volume performer. Everything will sound flat and too smooth until you crank it.

- Overall, most of the DRIVER QUALITY that are used on EJ07 sounded high quality except for its dynamic-driver. For reason, the bass quality felt like it was held back by its DD. And many has reported to have DD failure on their EJ07. Coherency wise, its pretty good. Not much timbre contrast.

- When it comes to BUILD AND COMFORT. It’s a mixed-bag. It is decently built. The clear-resin shell may turn yellow after sometime. The resin shell is on the thinner side. Owners may have to babysit their EJ07 quite literally. If you have a small ear like me, it’s going to be an issue. The comfort issue can be mitigated by swapping to a smaller size ear-tips but it still feels chunky to the ears.

So far It performs quite well for what it's trying to be. But how does it stacks against some of the well-known tribrids?

Here's a simplified HEAD-2-HEAD

IO VOLARE x TANGZU SANCAI BALANCE (M) vs
ALPHA OMEGA x KBEAR WIDE 8C GRAPHENE x TANGZU SANCAI BALANCE (S)

<BASS>
● Bass-Shelf : RA > V > EJ
● Tonality (Warm-Neutral-Dry) : V (WN) > RA (WM) > EJ (N)
● Subs Extension/Quantity: RA > EJ > V
● Subs Attack : RA > EJ > V
- RA has the highest pressure, EJ is close behind. V softest abit loose abit a muffle.
● Sub-bass kick: RA = dung-dung > EJ = thung-thung > V = bhung-bhung.
● Sub-bass detail/texture: EJ > RA > V
- Although, the EJ don’t have the same volume as the RA, EJ subs have better clarity and detail. V rumbling detail & texture is the weakest.
● Ghetto Bass (elasticity/decay rate): EJ > RA > V
- The EJ is bounciest.
● Bass Distortion: EJ > RA > V
- The EJ’s has the clearest bass distortion.
● Bass Drop: EJ > RA > EJ.
● Mid-bass Presence: RA > V > EJ
● Mid-bass Attack (Punch/Slam/Thud): V > EJ > RA,
- The EJ hit faster and slightly deeper than RA but RA hits bigger, thicker and heavier. Meanwhile V is a mixture of the 2, it carries similar width and depth in terms of impact of the RA but slightly slower than EJ and RA.
● Mid-bass detail/clarity: EJ > V > RA
- The EJ mid-bass is cleaner and clearer than RA but RA has greater substance. V sits in between EJ and RA with a hint of more warmth than the other 2.

<MID-RANGE/VOCAL>
● Mid-Range/Vocal Intimacy = EJ > V > RA.
- The EJ has the most forward, biggest image resolution of the 3.
● Male Vocal: RA > EJ > V
- The RA just hits the right balance in terms of note-weight, clarity and energy. The EJ lacks abit of that density and overtone. On V, it can sound push-back or thinner at times.
● Female Vocal: EJ > V > RA
- The EJ performs at higher octave while the RA is better for lower-harmonic female. V is in between. Overall, EJ performs better since it has no sibilance issue, greatest clarity with decent timbre.
● Voice Range: V > RA > EJ
- The V & RA seems to have slightly higher extension. The EJ can sound a tad too safe and boring lacking that of crescendo on transient.
● Transparency: EJ > V > RA
- Nuances like breath, instruments hits can be heard a hair clearer on EJ.
● Clarity: EJ > RA > V
- Sometimes V vocals have a hint of haze/grain and the background is not as pitch-black vs the EJ or RA. The EJ is super clean by comparison.
● Tonality (Warm>Neural>Bright): V(W-N) >RA(W-N) >EJ (N)
- The V has more apparent warmth to the voice/instrument. The RA slightly less. The EJ is almost uncoloured.
● Tone & Timbre: RA = V > EJ.
- Depending on tracks the RA and V can out-performed each other, their mid-range somewhat sounds more natural and whereas EJ can sound too clean and neutral.
● Transient/Attack: RA > EJ > V
- The RA seems to have heftier note-weight. The EJ is fast but less impactful. The attack on V is the softest. These traits will become most apparent on instrumental replay such as pianos/guitars/violins/strings.
● Airiness: V > EJ > RA.
- The V sounds abit more airy-er thanks to its treble extension.
● Reverb Level: V > RA = EJ.
- Due to longer decay, elements of overtone are better on The V. While EJ and RA are night equal.
● Sibilance Control: EJ > RA > V.
- The EJ had 0 sibilance issue. The V is the least forgiving here. V has higher tendencies to get sibilance on male than female.
● Shout Control: E J> V > RA.
- The EJ the most anti-shout set of the 3. The V comes in 2nd with borderline control. While with the RA, it can get abit hot on some female vocal but it is never too shouty.

<TREBLE/HIGHS>
● Tonality (Dark->Neutral->Bright): RA (D) > EJ (DN) > V (NB)
- RA treble region is the most veiled here with V is being the brightest, the most sparkling here.
● Air-Extension: V > EJ > RA
- V have the most air presence among the 3. The EJ and RA are closer to each other.
● Evenness: EJ > V > RA
- All of them doesn't sound peaky on low-vol. but once you listen to them louder, the peaks will start to show up. Hence, the result.
● Transparency: V > EJ > RA.
- V has the best transparency here. You do hear abit more twinkly-sparkling detail with the V. But the EJ is close behind while the RA seems to have the lowest-RES here.
● Clarity: EJ > RA > V
- Quite consistently, there is a layer of haze or micro-grain somewhere around the treble region with the V and it sounds busier, RA is seemingly cleaner. While the EJ is simply the clearest and the cleanest.
● Timbre: EJ > < V > RA
- Sometimes the longer decay on V makes constant hi-hats/cymbals to linger longer than it should. RA consistently has the more natural decay with EJ being 2nd. E-guitar replay on V is the most satisfying here with its wider attack and energy it carries. The EJ’s E-guitar is abit muffle by comparison due to softer attack and less weighty. The RA does abit better due to its heftier E-guitar tone. The EJ doesn’t like rock/metal music. But with Saxophones as well as synthetic noise such as electronics zing, shimmer, twinkling, distortion etc, the EJ takes it.

"If you're after for smooth bassy sound, the RA is the best choice here. Despite it's short-coming in technicalities, it is such a pleasant set to listen to. The VOLARE is the most well-balanced here, the better all-rounder and probably the safest pick of the 3, but it is kind of boring, The EJ07 on the other hand sounds the most special here. It has that X-factor that makes audiophiles long after this set. That immersive staging and high level of clarity is truly something else. though, It is not going to be for everybody. But it will my personal pick which is why I owned one."

◤FINAL THOUGHTS◢
The EJ07 has been around since 2019. Even till today, it is liked and loved by many audio-enthusiast out there and for a good reason. To my ears, the EJ07 has many flaws that could become a deal breaker for some. The diffuse-field like tuning is very uncommon. It could be categorized as a niche set and may not work for some genres. And timbre wise, it is not the most organic in the grand scheme of things. But the magic of the EJ07 lies in its staging and volume scaling. It is unlike anything I’ve heard. From my limited experience, I do not recall anything that can do what the EJ07 does below a 1000$ USD. And because of that, it has become a legendary set and has been sought after by many audiophiles with acquired taste.

[MY PERSONAL HEAD-FI GRADING]
1 ★ - Appalling! please avoid this!
2 ★★ Subpar offering, there are better options out there!
3 ★★★ Decent with some caveats! Not a bad pick!
4 ★★★★ Not perfect but solid choice ! This should be in your shortlist. A nice addition to your collection.
5 ★★★★★ One the best in class! You should go right ahead & buy one! A must have!

ALPHA OMEGA RA 3 ½ ★★★

▓▒░ SOUND-SIGNATURE ░▒▓
The RA is a sub-bassy, V-shaped-ish kind of set. Surprisingly, it doesn't sound that aggressive. It sounds more civilized than one might expect. The bass presence is noticeably higher the rest of the frequencies. However, the mid-range offers a good level of intimacy. The lower-mids is neither too recessed or thin. While, the upper-mids has ample of energy with a smooth overtone for a natural vocal rendition.
The treble is definitely on the darker side of the spectrum but it is well executed to keep everything sounds natural.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
- It is a sub-bass oriented bassline. It is thick and sturdy but not as aggressive as you might think.

- The sub-bass presence is plentiful. It extends well down-low with a good amount of sustain. The attack is on the softer side with a neutral rate of decay, that is neither too fast or too long. Other than that, the elements of bass distortion and electronic farts is well heard.

- The mid-bass to upper-bass has a lesser prominence but it still delivers a decent sense of punch and slam when it is call forth.

- Sadly, the ghetto bass replay is not very satisfying. The bound & rebound rate is on the stiffer side. It just doesn’t sound bouncy enough.

- Despite being a bassy set, the elements of reverb or echo is not the most distinct. Which is a typical issue I've found on most resin-based set.

- Although the bass volume is high, it not the most detail bass per say. The sub-bass texture is quite blunted while the mid-bass is not the snappiest nor the tightest in its class. As a result, the sub-bass and mid-bass doesn't have the best of layering as they tend to blend in together. It's got the quantity but quality its lacking still. The dynamic is not there yet. As if the low-end is done by a balance armature rather than a good dynamic driver. And for bassy set, that is questionable.

▓▒░ MID-RANGE /VOCAL ░▒▓
- Despite its bassy nature, the mid-range is quite well separated from the lows which give its mid-region a good amount of clarity.

- Overall, the mid-range in on the intimate side but it is not overly forward.

- Thanks to the warmth coming from the lower harmonics, the overall vocal reproduction sounded lush and rich regardless who sings. Chesty-male vocals seems to benefit from this attribute the most, while high-pitch female tend to a sound a tad too thick.

- Speaking of female vocals, the higher-pitch of the voice has been dialed-down a little. There are times when female vocal just lack that last bit of extension that it needs. Depending on the songs, the vocal can lack that sense of airiness to them. And they don't seem to shout or scream when they do. Its evenly smooth upper-mids response makes it a good "anti-shout" set. Thankfully, they sound energetic enough to not sound boring.

- But what's not so good the RA is instrument like pianos, strings, violins, guitars will sound rather blunted on the attack which is not ideal if you're listen to OSTs or BGM tracks.

- Yes, the vocal transparency is not its strength. Some of the vocal texture or nuances are smoothed-over but it is not severely lacking in micro-detail. At the very least there is no such thing as grainy artifacts, harshness or edginess is heard. There is with a whiff of sibilance issue on some vocals but its bearable. All and all, it gives listeners a smooth and euphonic vocal experience that is soothing to the ears.

▓▒░ TREBLE/HIGHS ░▒▓
- The treble response is probably one of the darkest among the tribrids I’ve heard. It rolls-off way earlier than expected. Airy and open sounding treble is not what it is aiming to be. With the bass region dominating the tri-frequency, it is bound to happened.

Most of the time, the treble performance is carried by the lower part of the treble region which gives off a decent amount of energy and sparkles.

- The treble may not be the most transparent in its class but it sounds remarkably clean and clear. The level of clarity it possesses is what gives the treble a good sense of definition. Despite its darker nature, most of the treble elements can still be heard if you paid attention closely. It's got none of those degrading qualities such as grain, haze or distortion at all. It is surprisingly well-sorted in its response. Unless you cranked the volume up-high, there is hardly any unwanted resonance or peaks is heard.

- Having said that, the treble could use with a better attack definition. They can come across a tad too veiled or smooth-out in the mix. Instruments like cymbals, constant hi-hats or even percussion like drum-hit will have a more smoother-edge to them. Meanwhile, synthetic noise such electronics zings, shimmers or electric guitar seems to lack that extra bite that it needs. Thankfully the decay-rate was on point as the note ends when it needs to be.

- Despite the inherent flaws, the treble is still reasonably well-tuned. It is never offensive to listen to which is very ideal for a fatigue free listening session.

- Other than that, it is extremely forgiving to low-fi tracks. Most of the time you'll get annoyed by those poorly recorded tracks. But with the RA, it gives you a peace of mind. Gone is the bad artifact.

- In-short, from a dark treble perspective, this level of treble performance seems to work rather nicely.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The RA's HEAD-STAGING is pretty ordinary. The perceived stage dimension is not that expansive. It is not the widest nor it gives much depth to the stage. However, the head-room is surprisingly tall. That must be the vent doing its work. As a result, the overall presentation is more on the intimate side. Each of elements of sound were still be given an adequate amount of space, even when the stage is crowded.

- The SPATIAL IMAGING OR INSTRUMENT PLACEMENT between channels are quite accurate but due to the darker treble response, the image-placement is not razor sharp.

- Which also affect its LAYERING AND SEPARATION capabilities. The vocals and instrument are mostly well separated. They never seem to face a major congestion issue. However, the separation level isn’t the best in class. With the imaging prowess aren't as vivid, those separated elements doesn't have the clearest spot.

- The overall RESOLUTION AND DETAIL RETRIVIAL is slightly behind its rival. But on the grand scheme of things, the level of micro-detail is not severely lacking when considering its tuning approach.

- The overall TONE AND TIMBRE is not the most analogue I’ve heard but it is by no means unnatural. Though the notes are nicely weighted, in the pursuit of being smooth, most of the attack-definition are softened which causes instrument hits to sound abit blunted and muffled. This very essence takes away some of the realism of the music.

- The DYNAMIC-RANGE is mediocre at best. Most of the time, the notes could use with greater impact as the contrast between the loudest and softest is quite subtle.

- The VOLUME SCALING is complicated. It cannot be played on lower volume as it will sound too bassy and low-res. But if you crank it too high, the treble will start to get peaky. The sweet spot is around low-mid volume [YMMV].

- Based on the specs, the DRIVER QUALITY is top notch. However, the implementation is not quite there yet. I believe you could squeeze more performance out of that 7-drivers. And not mention, it requires more power to achieve good fidelity. On a low powered AMP, it can sound underwhelming. At least, driver setup sounds coherent and harmonious with minimal timbre contrast. And its got no driver-flex issue.

So far It performs quite well for what it's trying to be. But how does it stacks against some of the well-known tribrids?

● Airiness: V > EJ > RA.
- The V sounds abit more airy-er thanks to its treble extension.
● Reverb Level: V > RA = EJ.
- Due to longer decay, elements of overtone are better on The V. While EJ and RA are night equal.

- V have the most air presence among the 3. The EJ and RA are closer to each other.
● Evenness: EJ > V > RA
- All of them doesn't sound peaky on low-vol. but once you listen to them louder, the peaks will start to show up. Hence, the result.
● Transparency: V > EJ > RA.
- V has the best transparency here. You do hear abit more twinkly-sparkling detail with the V. But the EJ is close behind while the RA seems to have the lowest-RES here.
● Clarity: EJ > RA > V
- Quite consistently, there is a layer of haze or micro-grain somewhere around the treble region with the V and it sounds busier, RA is seemingly cleaner. While the EJ is simply the clearest and the cleanest.
● Timbre: EJ > < V > RA
- Sometimes the longer decay on V makes constant hi-hats/cymbals to linger longer than it should. RA consistently has the more natural decay with EJ being 2nd. E-guitar replay on V is the most satisfying here with its wider attack and energy it carries. The EJ’s E-guitar is abit muffle by comparison due to softer attack and less weighty. The RA does abit better due to its heftier E-guitar tone. The EJ doesn’t like rock/metal music. But with Saxophones as well as synthetic noise such as electronics zing, shimmer, twinkling, distortion etc, the EJ takes it.

"If you're after for smooth bassy sound, the RA is the best choice here. Despite it's short-coming in technicalities, it is such a pleasant set to listen to. The VOLARE is the most well-balanced here, the better all-rounder and probably the safest pick of the 3, but it is kind of boring, The EJ07 on the other hand sounds the most special here. It has that X-factor that makes audiophiles long after this set. That immersive staging and high level of clarity is truly something else. though, It is not going to be for everybody. But it will my personal pick which is why I owned one."

◤FINAL THOUGHTS◢
My feelings on most Alpha Omega products have been rather lackluster. But with the RA, I quite like it. I don’t mind recommending the RA, if you’re searching for a smooth bassy set. Yes, for around 570$ USD, it does not represent a great value. First off, the tuning is not going to work for everybody. Secondly, from a technical stand-point, it falls short ever so slightly behind its competitors but that is not the reason you buy it. You buy the RA because you love the tuning. To me it is a guilty pleasure set. If you love it, you’ll order one.

Unfortunately, it doesn’t fit my ears well. I guess it is not meant for me. So, be sure to try it out beforehand. Do not blind buy the RA.

SOUND IMPRESSIONS & USER EXPERIENCE:
[SOUND QUALITY 7/10 VALUE: 4/10] [NEUTRAL-BRIGHT]

▓▒░ SOUND-SIGNATURE ░▒▓
- Neutral bright with a sub-bass boost. Quite cold in tonality. It gives off an intimate presentation with the bass, mids and treble having nigh equal forwardness within the tri-frequency band.

▓▒░ BASS/LOW-END ░▒▓
- It's got a fast, clean, tight response with a sub-bass oriented character. The overall bassline has this cold and analytical demeanour to its approach.

- The well-extended sub-bass offers great presence and texture. The sub-bass kick is punchy while rumbling effect has good amount of pressure and sustain. The ambience level is decent to keep things atmospheric but the elements of reverb and echo are not well defined.

- Sadly, the mid-bass is on the lean side. There is not much emphasis here. The attack is soft and not much depth to the hits. And in terms of warmth or body it is quite lacking. The ghetto bass replay is bouncy enough with zero bleed onto the lower mid-range.

▓▒░ MID-RANGE /VOCAL ░▒▓
- Overall, the mid-range/vocals are rather forward in the mix. The vocal reproduction has good clarity and transparency at the expends of fullness and richness. The lower harmonics just don’t provide enough warmth and body to the lower mid-range. Hence, there is a hint of dryness on vocal transient, especially on male vocal.

- It just lacks a touch of sweetness and euphony on vocal replay as it sounds more analytical than musical. And the lack of reverb overtone on vocals doesn’t help either. Some of would deem its mid-range to be abit flat or soulless, void of emotion. And it couldn’t be further than the truth. The coldness of the bassline and the brightness of the treble really put a toll on the tonality of its mid-range.

- The same true can be said with its instrument replay, they sound crisp but lacking note-weight and not very dynamic. Having said that, despite its monitoring nature, there hasn’t been any grain or harshness issue is heard.

▓▒░ TREBLE/HIGHS ░▒▓
- Regardless of filter-mode you’re in, the treble is on the bright side but not in the best possible manner. It is not piercing or peaky by any means. There is a good amount of crisp to the notes but they sound rather dry and flat with a hint of metallic edge. It can sound almost shrill or brittle depending on gears. Hence, affecting the naturalness of timbre. There is not much weight to the notes.
- The dynamic can sound quite compressed here as everything just sounds equally loud. The transient could use with a wider range of attack. Constant hi-hats and cymbal crush are more to the fore and tends to linger a little too long which can cause fatigue. While synthetic noise such as electronics, the zinging or shimmering will not have the most satisfying replay.

- The dryness is really something else to appoint that it dries my eardrum. Even on a dark set like my EJ07 or EST112 (loan), I am struggling to listen to them for a longer period of time which is not a very good sign. The bassline is largely responsible for this as there is not enough warmth & moisture to counter balance the brightness and the dryness of the highs.

- At the very least, the clarity and transparency is there to backed it up. The air extension is adequate which gives a nice sense of openness to the stage. There is no unwanted resonance with almost zero issue with sibilance.

- The treble overall sounds very clean. It’s got none of those grains, haze, distortion or any sort of dirty noise which is great. Sure, it’s got its strength but that “dryness” I mentioned earlier is not going to work in everyone’s favor. Those treble sensitive folks and timbre-heads might want to take note.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The SOUND-FIELD is quite wide, giving an out of ears experience. From an intimate perspective, it’s offer good depth and adequate head-room.

- In terms of IMAGING PROWESS. It’s quite competent. Instrument positioning is sharp and accurate while transition of sound between channel is smooth and clean.

- It’s SEPARATION & LAYERING process is quite competent and it is mostly consistent. Doesn’t seem to struggle all that much on a chaotic passage. Due to the treble being abit hazy, the background is not the blackest. But its forgivable.

- DETAIL-HANDLING, be it macro or micro are well done. I don’t find it to be that inferior versus its competitors.

- As for the DYNAMICS, it’s a mix-bag. Depending on your playlist it can either be compressed or expand. Most of the time, it’s offers good balance between being energetic and laid-back.

- The TONE AND TIMBRE proved to be the S9PRO+ Achilles’ heels in its pursuit of chasing higher fidelity. One of the biggest let-downs is that constant dryness issue. The other thing is the note-weight is abit lacking. And the reverb overtones are not well received thanks to the quick decay and release. All that add up took a huge toll on its musicality. In other words, the sound it produces is not very pleasant.

- The device is WELL BUILT. It is small, light and seems durable.

- The DRIVING POWER is average at best. The AMP on both SE and BAL is more than enough for most IEMs but might struggle on more demanding headphones. The power delivery is HISS-FREE with abit of CLIPPING NOISE when changing tracks.
- Unfortunately the POWER-DRAW is not that efficient. It is quite power hungry. But it is not detrimental.

- As for HEAT-MANAGEMENT is very good. It is not that hot on longer usage.

- Speaking of FEATURES, it does not offer an independent volume control. The increment of volume per steps is not many but it is not that powerful so, it is more than usable. The gain is fixed, as I don’t see any gain-switch on user’s manual. Thankfully, it does provide a 6-ways of digital filters which gives a very subtle change to your music. Its very easy to operate. Not a bad feature.

- As for SYNERGY, it is best to pair the S9PRO+ with a warm and less technical gears. Due to it’s sound profile, it is not a very versatile DAC.

- For 139USD retailed, it is not very well priced. There are much better offerings for half the PRICE. But it does go on sales quite often for around 89USD.

~ HEAD-2-HEAD : IN-DEPTH COMPARISON ~

VS TANCHJIM SPACE [DUAL-CS43131] x BAT AUDIO OTG
[SOUND QUALITY 8/10 VALUE: 8/10] [NEUTRAL-BRIGHT]

"My nearly 1 year old Tanchjim SPACE OTG connectors has gone loose. Hence, I’m using an aftermarket OTG during the test which may alter the sound by 5% at best."

● They both went for a neutral-bright tuning with minimal sound colouration. But the SPACE has a hint of organic touch that makes its sounds more natural.

● The low-end of the S9PRO+ has a greater presence overall. One of the major differences is the SPACE will have a slight mid-bass biased while the S9PRO+ is a more sub-bass oriented. As a result, the sub-bass punch, rumble and grumble has higher pressure and texture. The SPACE mid-bass on the other hand has more meat. It has better extension and hits deeper with longer, more precise decay. The SPACE bassline offers more natural response which prove to have positive effects on its upper harmonics.

● The SPACE will come across as the more mid-centric of the two. The bass and treble elements took a slight step back giving the mids/vocal more room. However, it doesn’t sound as intimate as the S9PRO+. And the vocals on the S9PRO+ has slightly better transparency as well. The voice just carries more nuances. However, the reproduction of vocals on SPACE has more solid fundamental grounds. It carries more body and weight without losing much clarity. It sounds sweeter and more soulful by comparison. It managed to strike the right balance between euphony and clarity which makes it sounds the more natural of the two. Instrument-replay such as strings, guitar, piano and flute seems to have equally good performance.

● The SPACE treble response is certainly bright but perhaps not as bright or dry or as forward as the S9PRO+. The treble response is much more pleasant with the SPACE. In actuality, the treble of the SPACE has slightly more sparkle up top but for some reason it doesn’t dry up your eardrums like the S9PRO+ did. Constant hi-hats and cymbals aren’t as fatiguing with a more precise decay. While electronic zing has a nicer ring to them. Treble sensitive folks will have a better experience with the SPACE. It just has the right balance of bite, edge and crispiness without being too aggressive or soft which can make a treble lover rejoice. And this effect is pretty much consistent across all gears I’ve tried including their very own Hidizs MP145. I find the SPACE’s treble to be well defined yet refine.

As for technical performance:
● The SPACE sounds less intimate; not as wide but offers more depth and head-room in return.

● The blacker background of the S9PRO+ helps in giving it’s separated elements a clearer cut. Giving the S9PRO+ a slight advantage on separation and layering.

● Imaging/instrument placement is slightly sharper with the S9PRO+.

● MICRO-DETAIL with go to the S9PRO by a slight margin, as for DYNAMIC-RANGE, they trade blows.

● One thing that the SPACE does way better than the S9PRO is when it comes to TONE & TIMBRE. Other it’s denser note-weight, it is better at retrieving those elements of reverb on vocal and instrument. It’s got a believable transient attack with more precise decay and better level of sustain. Hence the notes often sound more complete from end to end with the SPACE.

● Next to the S9PRO+, the SPACE is more versatile when it comes to SYNERGY. Still, it is best to pair with warmer, darker gears.

● The SPACE has greater DRIVING POWER with better POWER/VOLUME MANAGEMENT. It’s got gain-switch and independent volume control unlike the S9PRO+.

● The SPACE seems to be more efficient on power-draw but slightly heavier and hotter upon usage.

● The SPACE cost only 89.99 USD retailed. It is nearly 40% cheaper which presents great value vs the S9PRO+ (139USD).

With my money, I’ll still go with the Tanchjim SPACE, it may not be as technical as the S9PRO+ but it does a lot of things more correctly. The more natural timbre of the SPACE is what gravitates me towards it more than S9PRO+

◤FINAL THOUGHTS◢
The Hidizs S9PRO+ then is by no means a terrible dongle. Unfortunately, on the pursuit of chasing higher fidelity, its started to lose sight of what is important which is the naturalness of tone and timbre. It does not need to achieve a 10/10 score on timbral accuracy, it only needs to sound natural enough to our ears. And it didn’t quite do that well. Sure, Hi-RES sound will definitely impress you on short-blast but on longer sessions, the naturalness of tone and timbre will play a bigger role. Once you notice that off-timbre, you just cannot go unnoticed. I find it quite hard to recommend to people especially with that 139$USD price-tag. Even on a 50% discount, it’s hard for me to vouch. I recently reviewed the COLORFLY CDA M1P, I do prefer that quite abit. Preference aside, I’m sorry Hidizs, you have to do better than this. Competitions are tough these days!

COLORFLY CDA M1P 4 ★★★★

SOUND IMPRESSIONS & USER EXPERIENCE:
[SOUND QUALITY 8/10 VALUE: 9/10] [Warm-Neutral]

▓▒░ SOUND-SIGNATURE ░▒▓
- It sounds warm, smooth, rich with organic tone & timbre.

▓▒░ BASS/LOW-END ░▒▓
- The low-end has good presence and control without being too domineering. It has a slight mid-upper bass biased with adequate sub-bass pressure and sustain.

- There is a noticeable sub-bass roll-off on the lowest region of the bassline. Those sub-bass kick and rumbling sensation has been dialled down a little but it is not severely lacking.

- The mid-upper bass region has greater density. It’s thick and thumpy. It does bleed ever so slightly onto the low-mid-range, giving vocal and instrument a welcoming sense of body and warmth.

- The overall bass layering and dynamic is good but not outstanding. The bass attack is not going to be the most visceral in class as it remains gentle but still impactful. The decay-rate is excellent especially on filter 1-2. All and all a solid bass performer.

▓▒░ MID-RANGE /VOCAL ░▒▓
- The greatest strength of the M1P lies in its mid-range presentation. The vocal and instrument will come across more to the fore.

- It may not have the highest level of vocal transparency but the richness and fullness of vocals is something many people would appreciate. The energy from the lowest to highest voice range is well dispersed.

- Having said that, the naturalness of vocal transient remains top-notch, it's got none of that edginess, sharpness or metallic sheen regardless of pairing.

▓▒░ TREBLE/HIGHS ░▒▓
- As for the highs, due to the intimate presentation, treble elements are well received without overly sharp or smoothed-out despite going for the more laidback, warmer approach. The brightness hits right on the sweet spot without being overbearingly hot or shrill, combined with that warmish low-end, it is quite the pleasant experience. The treble remains evenly smooth and well-extended with acceptable air presence. This trait allows it to pair with wider-range of sound-profile.

- It’s got none of that harshness, grains, distortion or any unnecessary noise which could degrade its refinement.

- As for the downsides, the treble could use with abit more bite for added definition. Secondly, it is not the most forgiving to sibilant tracks. Even so, the sibilance does not come across as piercing which is great. And it has to be said that, it is not so forgiving on low-fi. Hence, most of the bad artifacts on recordings can’t go unnoticed. Other than that, there isn’t much to complaint when considering the tuning it’s trying to achieve.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The HEAD-STAGE plays with more width than height with adequate sense of depth. For an intimate or immersive presentation, the space and dimension doesn’t seem to be lacking.

- As for 3D/IMAGING factor, it is not it’s strong point. The instrument placement or transition of sound between channels are mostly accurate but not razor sharp.

- When it comes to SEPARATION & LAYERING, clearly, it is not class leading. The background is not pitch black while the gap between each element isn’t generous due to that close, intimate staging. Hence, any gears that doesn’t have good separation prowess tend to struggle on busier tracks.

- The MACRO-DETAIL though is good, the MICRO-DETAIL is lacking behind versus some of its competitors. - And the dynamic-range isn’t that high. As a result, it is not going to reward listeners with pure music engagement but rather a relaxing and smooth experience. But it will be exaggerating to say that it sounds uninspiring, soulless and dull because it isn’t.

- The reason you get the M1P is because of its organic TONE & TIMBRE. It’s got none of that artificial attribute that can sometimes irk timbre-heads. The richness and fullness to the sound is quite addicting. Plus, that laid-back nature gives it a soothing experience which is great on longer listening session.

- As for the BUILD, it is very solid but it is quite heavy. Definitely one of the heaviest dongles I’ve tested.

- It's DRIVING POWER is great. Amplification-rate on low/high gain for both 3.5 SE or 4.4 BAL out-put is pretty high. And more importantly, it delivers a hiss-free power delivery. Pairing with sensitive gears shouldn’t be a problem.

- Unfortunately, the power-draw isn’t the most efficient. The heat management could be better as it can get as hot as your coffee or tea.

- As for FEATURES, it provides an independent volume adjustment (with small increment volume steps), 2-way gain switch and 6-level of digital filters (give subtle difference) with a tiny LED indicator which is very user friendly.

- As for SYNERGY, I’d recommend pairing the M1P with something that is neutral or bright. With warmer gears, it can sound a tad too warm.

- And finally the PRICE, for a 79$ USD retailed, it presents an amazing value. It gives ample of performance for so little money.

~ HEAD-2-HEAD : IN-DEPTH COMPARISON ~

Vs TANCHJIM SPACE [Dual-CS43131] x BAT AUDIO OTG
[SOUND QUALITY 8/10 VALUE: 8/10] [NEUTRAL-BRIGHT]

"My nearly 1 year old Tanchjim SPACE OTG connectors has gone loose. Hence, I’m using an aftermarket OTG during the test which may alter the sound by 5% at best."

● The Tanchjim SPACE sounds less coloured by comparison. It sounds brighter, cleaner and clearer across the spectrum.

● The SPACE may not carry the same warmth, note-weight and thickness of the M1P but the SPACE will reward you with better bass dynamic and control. The bass seems to have better definition and layering too. The sub-bass is felt more than heard. Those rumbling sensation just resonate and vibrate harder while the sub-bass kick offers more punch. They both are somewhat tuned to have a slight mid-bass biased. But the SPACE hits faster, tighter and deeper. It is snappy and bouncy with almost zero bleed onto the lower mid-range.

● The SPACE is definitely the more mid-centric DAC of the two. In a sense that, the bass and treble took a step back within the tri-frequencies giving its mid-range/vocals a better spotlight. The SPACE offer better vocal transparency and clarity. But in-trade, it doesn’t have the richness or the fullness of the M1P mid’s. Despite that, there has not been any major dryness issue on vocal reproduction, at least with the IEMs I’ve tried with. Both male and female voice sounds natural as far timbre is concern. And not mention, the energy balance from low to high pitch is excellent. The same true can said with instrument replay. The overall transient-attack on strings/guitar plucks, piano hits just sound crisp yet impactful with adequate fundamental body to the notes.

● Yes, the space is noticeably brighter by comparison. But because everything doesn’t sound as intimate the M1P, those extra treble energy does not come across as being overly sharp or spicy. It is very well executed. The extension has minimal peaks and troughs with a tad more air presence. The treble has more bite and better define overall. I find that instrument like hit-hats and cymbal crash has a smoother and more precise decay. As for the downside, the SPACE is more source revealing than the M1P. And it might not work well with brighter gears as it can tends to sound abit too sharp on transient. The warmer nature of the M1P is a safer bet.

As for technical performance:
● The SPACE sounds more open; slightly wider with more depth and head-room.

● The openness to the stage gives each element of sounds a better space between them hence boosting the SPACE’s separation & layering prowess.

● The blacker background of the SPACE also helps in giving it’s separated elements a clearer cut.

● Imaging/instrument place is definitely sharp and move vivid with the SPACE.

● Micro-detail and dynamic-range is a step up with the SPACE.

● But the M1P with offer better note-weight and density with a more laid-back and softer transient.

● The SPACE will definitely synergy better with darker, warmer and less technical gears.

● The driving power and volume adjustment calibration are equally as good on both.

● The SPACE seems to be more efficient on power-draw and the device is not only lighter but also less hot upon usage.

● The SPACE is about 10$ USD more expensive than the M1P but given its superior technical performance, it is well worth it.

With my money I’d personally go with the TANCHJIM SPACE still. Other than being less coloured, it is more dynamic, great technical performer without sacrificing much musical factor while still treading on the lines of being natural.

◤FINAL THOUGHTS◢
To sum up then, the COLORFLY CDA M1P is a solid piece of kit. It is very reminiscing of the Hiby FC6 with a cut back in technicalities and dynamics for a fraction of the price. The Cirrus Logic based dongle has been reigning the market for the longest since the terrible Asahi Kasei Microsystems (AKM) factory fire incident. And I’m glad that to say that with the M1P, the velvety of AKM sound is finally back. If you’re looking for a budget dongle that is warm, smooth, rich with organic tone & timbre, I would totally recommend the M1P. And for 79$ USD, its a no brainer really.

@max pro hi. what was the mod? what changed and how did it affect the sound?

I don't like the cable very much. It sounds sibilant compared to my ddhifi cable.

The mod I did was adding a cap (10uf low esr)on RT6863D power pin. The sound stage increased, the bass went very deep but treble became a little sharp (rear piercing) so I reverted changes. You may try

LETSHUOER S15

Leisurely plays your library…

Pros:
+ Well-balance and mature tuning.
+ Good bassline performance from a planar stand-point.
+ Good mid-range substance and presence.
+ Plays male vocals rather well.
+ Anti-shout tuning.
+ The treble still runs high without put forward.
+ Low symptoms of planar timbre; have some of the least metallic treble.
+ Good for long listening session. Comfortable & Pleasant.
+ Not source picky.
+ Well-accessorized.

Cons:
- Pricing is a bit steep but still worth it IMHO.
- Sub-bass could use with higher pressure and sustain.
- Lower-treble recession is affecting the transient of higher-pitch female vocals.
- Treble clarity and definition are second-rate vs its rival.
- Micro-detail aren’t the best in planar game.
- Dynamic-range aren’t the widest. Not the most engaging.
- Does not have the blackest of background.
Hence affecting the clarity of instrument placement & separation.
- Staging & Imaging capabilities are just average.
- A smidge harder to drive than some of its counter-part.
- Not for treble-head nor bass-head.

LETSHUOER S15 4 ★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
The S15 fall within the variation of W-shape tuning. The S15 offers quite a well-balance sound with a slight mid-bass biased.

▓▒░ BASS/LOW-END ░▒▓

● It is undeniably bassy a set with a smooth, clean and fast response that is neither too energetic nor anemic. The sub-bass delivery is not its greatest forte. Despite it having an adequate sub-bass presence, it doesn’t really extend down low-end. The sub-bass lacks pressure and sustain. The quick decay and short sustain sacrifice some of the echo/reverberation overtones on vocal and instruments. Hence, the sub-bass kick and rumbling sensation doesn’t really resonate that strongly but it should be more than sufficient.

● The mid-bass is noticeably denser/thicker with greater prominence. The transient is fast but not with a lot of impact. The mid-bass punch and slam gives off adequate sense of thump and tactile boom for as long as you don’t expect a visceral attack coming from it. Regardless, the bass-drop rendering is kept clean and smooth, while the Ghetto bass have decent elasticity and rebound-rate on replay. The good having a speedy bassline is, even with a hint of leftover mid-bass spilling onto the lower mid-range, it doesn’t introduce any dirt of veil high up.

● All and all, the bass performance is good but not exceptional, partly because of the bass layering and detailing are mediocre at best. Dynamically, the low-end lacks a bit of engagement factor than a bass enthusiast would desire. In all fairness, it is pretty well executed from the lens of planar. Unless you’re a hardcore bass-head or a bass connoisseur, the S15 bass performance will render more than enough joy for most people.

▓▒░ MID-RANGE /VOCAL ░▒▓

● Surprisingly it quite the mid-centric in its presentation. In a sense that vocals and instrument that lies in this region appears to be rather intimate/forward within the tri-frequency. On the balance of “euphony” and “clarity”, the bias is tilted slightly towards the former. Vocals and instrument have good substance and presence. The vocals often come across as being lush and well-bodied as it is not missing any of those low-end-to-low-mid wetness or warmth. The energy dispersion from the lowest (deep male voice) to the highest (high female voice) range are well-judged. Both male and female vocalist performs nigh equally as rewarding on stage. There is hardly any shouty-ness, honky-ness, harshness or graininess upon vocal rendition which is an impressive feat.

● As for nitpicks? The vocals texturing (raspy, gritty, hoarse, breath etc) may have the best transparency but it is not severely lacking. Some of the elements of the reverb or resonance on vocal and instrument are not properly captured. Due to the slight coloration coming from the mid-bass and recession on lower-treble, there are times when female vocal that lives on the higher octave suffers from sounding a tad too thick/husky. And the intonation of higher pitch of female vocal can lack in energy when compromised. If cleaner and energetic female vocal is more to your preference, you might want to consider its main competitors instead. The overall transient-attack on strings/guitar plucks, piano hits and violin strums has a more rounded edge to them with a rather precise decay. Most instrument that lies in this region never seems to lack in terms of fundamental presence. The note hits aren’t the most distinct but don’t necessarily sound blunt per se.

● Regardless of its shortcomings, it does not stop its mid-range from being inoffensive and musical, as it maintains a good level of naturalness to the overall tone and timbre.

▓▒░ TREBLE/HIGHS ░▒▓

● Thanks to the warm hues coming from the low-end, it gives the treble a pleasant experience. It is quite cossetting to listen to. It is never tiring on longer session as well. Having said that, this level of treble performance might not give a strong impression for treble-heads out there as It just doesn’t carry the same brilliance and air in comparison to most planar. But it is not overly dampened to a point of being too dark and dingy. As a result, even with its relatively dark nature, synthetic noise such as electronics still gives off a nice sense of zing, shimmering or twinkling effect on the overrun. Not to mention, those metallic sheen or sharpness inherit by a planar-driver is seemingly less. In fact, the S15 has got some of the least symptoms of planar timbre, making it one the more natural sounding planar on the market right now. Throughout the test, there was no unwanted resonance is heard. The sibilance tolerance is very high while peaks and troughs are kept to a minimal degree, giving its treble a rather smooth response. Instruments like hit-hats and cymbals are very inoffensive as they’re not very distinct in the mix but the decay is noticeably smooth, keeping its naturalness in check. With the right synergy, one could actually crank the volume to quite a high degree without distortion issue.

● As for the downside, the treble definition is not the best in the game. Due to the darker nature of its tuning, micro-nuances will not be as transparent as some of its main rivals. The higher notes seem to have a smoother edge to them, those whom prefer a crispier playback might find it lacking a tad of bite. Fortunately, the treble decay is rather precise as it is smooth and doesn’t linger unwantedly.

● In short, the treble quality is good but top-notch. The treble still runs high without put forward. It’s got good qualities of naturalness combined with a mature response. But one thing for sure, treble sensitive people will greatly appreciate the S15. It is borderline inoffensive and more importantly, fatigue free.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
- The overall HEAD-STAGE is quite good. The headroom is decent with adequate depth but plays with more width. The mid-range/vocals have good intimacy without sounding overly forward while the bass have slightly more presence over treble region.

As for INSTRUMENT SEPERATION is decent. Being the stage not most grand or open sounding. The gap/spaces between each element of sound are mostly adequate but aren’t the most generous. On top of that, the background is not the blackest as if there is a thin layer of mist masking the vision of sound positioning which also has something to do with the darker nature of its treble response. As a result, separation process is not giving the clearest cut between elements. Hence, it is not the best when trying to reproduce a highly complex tracks as everything will starts to blend together.

- The STERO-IMAGING definitely not its greatest forte. INSTRUMENT PLACEMENT has accurate positioning but it is not the most vivid. Transition of sound between channels are smooth but not the sharpest on its projection.

- The DETAIL HANDLING is good but not outstanding. Therefore, monitoring or analysing music with this set is not your best bet. Macro-detail seems solid but micro-details don’t really pop as you’d expect from a planar driver. However, it does a remarkable job in highlighting detail in subtle manner rather than shoving everything onto your eardrums. Its DYNAMIC RANGE may not the widest. Therefore, is not the most engaging or emotional to listen to. This trait is pretty much aligned with its smooth and relax tuning.

- In trade, it possessed one of the more natural TIMBRE in its class. The metallic traits of the treble are still there but they have successfully tone it down to be more palatable for timbre-head. Vocals and instruments have a good sense of body to them. The attack on transient is fast but not the most impactful. The decay is mostly on the quick side of the tempo with decent sustain level and smooth release. In other words, note hits/instrument don’t sound unnatural but lacks a touch of realism to them. In a sense that you’ll hear it but lacks a just a touch of dynamic feel on replay.

~ HEAD-2-HEAD : IN-DEPTH COMPARISON ~

vs 2022 7Hz Timeless feat. Kinera Leyding.

BASS
- Timeless has better sub-bass extension & attack. Rumbling sensation has higher pressure & sub-bass kick has more punch.
- S15 mid-bass seems thumpier and has more body/thicker. Giving it a heftier and boomier low-end.
- Ghetto bass is bouncier with the S15. Bass distortion element is better captured with the S15.
- Due to slower decay and longer sustain of the Timeless, it makes it the warmer set of the two. The S15 may sound thicker but it’s a faster bass, seemingly colder in tone when comparing the two.
- Being warmer, the Timeless soothes its listener with a better sense of atmospheric ambience. Hence, it is better at capturing reverb and echo on instrument and vocals as well.

MIDS
- Timeless presentation is more intimate with higher pinna-gain.
- Male vocal on the Timeless have a slight sharpness on vocal transient. Due to added presence region and upper treble. S15 seems to do male vocal better as it is lusher, fuller and smoother as well.
- Female vocal on the Timeless is slightly leaner but it carries more energy up until the highest voice range. It doesn't face that insufficient energy that occurs on the S15 sometimes, which makes the Timeless the more emotional set for female vocal enthusiast.
- Vocal texturing and reverb is slightly better on the Timeless.
- Instruments like piano, xylophone, strings (guitar, electric guitar, violin, viola), flute has greater transient with longer decay and better sustain. Not only it sounds more distinct but also more complete from end to end of notes. But the S15 will have thicker note-weight. All of that is by a slight margin.

TREBLE
- Timeless has better treble extension overall. It sounds more airy and more open up top. It does sounds brighter and livelier.
- Timeless treble sounds clearer with more bite to them. Whereas on the S15 there is a hint layer of haze which makes it not as clean.
- Synthetic noise, electronic zing and shimmer sounds crispier with the Timeless.
- S15 seems to have better mid-treble presence. Piano key for e.g that lives on this region has better clarity.
- Timeless has more apparent planar timbre; can sound a tad too sharp especially with brighter DAC/AMP.
- S15 treble has more laid-back nature. It is will be better suited for treble sensitive folks.
- Hit-hats & Cymbals on the Timeless is better define with good decay.

STAGING
- The Timeless sounds a tad wider which extend just behind your ears. But the S15 offers slightly more depth. In terms of height, they're nigh identical. ~~The MP145 is still there King of stage in planar game.~~

IMAGING
- Transition of sound between two-channel and sound localization is definitely sharper and more vivid with the Timeless. Spatial cues have a clearer image overall.

LAYERING & SEPARATION
- Both of them offers just about the same space & gap between elements. Due to darker background on the Timeless, each element of sound has a clearer cut.
- Both tend to suffer just a tad on busier tracks. ~~Something like the MP145 has better consistency in maintaining each border of sounds.~~

DYNAMICS
- Clearly, the Timeless has a wider sense dynamic-range from top to bottom.
- It’s more fun. Its more emotional. You're mostly in tune with your music.
- The S15 is a bit more laid-back and chill, sounding less attached to your music.

DETAIL RETRIEVAL
- Other than mid-bass and mid-treble region, the Timeless is better defined. Micro-nuaces seems to have ever so slightly better clarity and transparency.

TIMBRE
- None of them sounds inorganic or unnatural to my ears.
- The S15 will offers more note weight across the range and has lesser planar timbre; sharpness, metallic-ness of treble.
- However, the attack on the Timeless is more incisive with the decay being slightly longer and the notes has higher level of sustain. The reverberation /echo on the overtones makes the sound even more complete as a whole. Hence, most of the time, I find the note definition of the Timeless is more complete from end to end. Some of this attributes are slightly missing with the S15.

"If you prefer more sub-bass, more emotional female vocal with better treble clarity or something that is more fun in general. The 7hz Timeless is the one to pick.
However, if you like something that is more laid-back, less offensive, listen a lot to male vocals, and very allergic to planar timbre. S15 is the better buy."

◤FINAL THOUGHTS◢
The S15 do have its own place in planar market. It has some good qualities that can attract listeners as none of its competitors follows the suit of its tuning. It is not a set that will wow you on short blast, but it is a set that you’ll appreciate on longer sessions. Unless you have a specific acquired taste for a profile, then it can either be a hit or miss. My biggest gripe with the S15 is not really the performance but rather the price-tag itself. For about the same amount of money, you could actually buy the MP145 and 7hz Timeless together which is not a good sign in terms of value. However, some people would actually take the S15 over the other two in a heartbeat. I knew quite a number of audiophiles whom enjoy this set thoroughly. They really shower praise this set quite abit. And I can see why. Beside the 7hz Timeless, S15 is definitely one of my favourite Planar I’ve tested. I ended up liking it more and more, the more I spent time with it.

Binary x Gizaudio - Chopin 4 ½ ★★★★

▓▒░ SOUND-SIGNATURE ░▒▓
It is neutral with a bass boost. The tri-frequency is relatively well-balanced. The bassline is sub-bass oriented with a relatively shy upper-mid-bass presence. The mid-range/vocal are rather intimate with a more forward upper-mids/female vocals. The treble has a nice smooth roll-off with adequate air presence.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
● The bassline is well very executed. It has never come across being overly forward or too energetic. It is powerful but not forceful. The low-end has a very pronounce sub-bass that extend quite down low. The rumbling and booming effects are well-textured with great control, thanks to its precise attack and decay. Alongside that, it’s very capable on retrieving those reverbs and echo which are often present in the background or vocal replay.

● The mid-bass doesn’t quite carry the same vibe and energy. It is more reserved by comparison, especially on the upper-mid bass region. The attack is by no means soft, it’s just lacking forwardness. As a result, any kick, slam, punch and thump will not have the most satisfying replay, lacking that initial impact on transient.

● Despite that, the bass control is excellent. There is hardly any bleed or bloat that could potentially impedes its mid-range. Only on a very busy tracks, that the bass will struggle just a little. Energy wise, it may not have the best balance between sub-bass to mid-bass but the overall bass texturing and layering is quite solid for the price.

▓▒░ MID-RANGE /VOCAL ░▒▓
● The mid-range is probably its greatest strength. The overall presentation is on the intimate side with a smooth and clean replay. It offers great balance between euphony and clarity. Vocal transparency isn’t the best in class but in trade, it offers listeners with a pleasant vocal reproduction.

● The leftover warmth coming from its bassline truly helps in giving its vocals and instrument an adequate amount of body/heft that it needs. Some male vocals may not have the best reproduction as they prefer a lusher, richer and deeper tone for added presence. As female vocal is more rewarding here. They’re more engaging to listen to. But some of the upper-range of the voice has been trimmed out which makes it’s a more forgivable to shout or scream. Some might find it restraining but to most people, it is the safer approach. And not to mention, there is not even a single BA-grain is heard which is impressive.

● Most instrument that lies in this region never seems to lack note-weight. Overall, transient on strings/guitar plucks, piano hits and violin strums have a more rounded edge to them. Regardless, it’s mid-range still come across as musical and natural.

▓▒░ TREBLE/HIGHS ░▒▓
● The darkish response gives its treble a nice sense of warm hues to the highs. Having said that, air-extension is still presence though. It’s got just about enough brightness and forwardness to not sound dim. There is almost zero unwanted resonance coming from the highs. It remains fairly even up across the top-end.

● The attack is sharp enough with adequate note-weight. Hit-hats and cymbals have good timbre while synthetic noise such as electronic zings, sizzles or shimmering has a nice ring to them. This kind of tuning, make it’s a very suitable set for a long listening session. It is never fatiguing.

● Treble refinement is definitely one of the best among its competitors. It’s got none of those degrading qualities such as sibilance, peaks, grains, distortion, sharpness or metallic sheen. Treble definition is good but not top-tier which is to be expected. All and all, it’s a proper one. You really have to pay a lot higher to surpass this level of treble quality. Still, a hardcore treble-head might find it to sound abit too safe. If energetic and vibrant treble is your type of jam, you might find it uninspiring.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
The overall HEAD-STAGE of the Chopin is pretty decent. It’s got decent depth to stage but plays more width than height. The mid-range/vocals are more to the fore but not domineering. The instrument/background elements wrap around the vocalist with adequate sense of spaces between them. On busier tracks, the INSTRUMENT SEPARATION may falter just a tad but it is perfectly normal for this tier.

- The STEREO-IMAGING on the Chopin is competent enough. The instrument placement is quite accurate conduct but not the most vivid I’ve heard. The transition of sound between channels are rather well articulate. It flows from left to right smoothly but not the sharpest I’ve heard.

- The DETAIL HANDLING is not its strongest forte as it took on the more musical approach rather than analytical. But the level of detail retrieval is potent enough to carry its tuning. Its DYNAMIC RANGE is pretty good, it is not too energetic nor it is too boring. It carries just about enough emotions to keep you engaged to your music.

- As for the overall TIMBRE, it is quite natural. The BA timbre is kept to a bare minimum to keep timbre-head happy. Vocals and instruments mostly have good note-weight. The transient attack is neither too weak or too strong with the decay being smooth and precise. Hence note hits or definition may not be the most distinct in class but good enough.

- The CROSSOVERS between drivers are done with great finesse. There timbre contrast is hardly noticeable and there is no major out of phase issue which is just excellent. And there is no driver-flex problem as well.

~IN-DEPTH COMPARISON~

TANCHJIM PRISM X HAKUGEI SKYRIM FEAT.SALVATION ACCESSORIES X SPINFIT CP100 (M)

[Since it is not running on stock cable, I shall denote it as “PRISM+”]

● Right of the bat, The PRISM+ will come across as the more energetic set. To my ears, the PRISM+ bassline is more dynamic. It’s bouncy, more elastic, better layered and offers better balance between sub to mid-bass presence. The mid-bass just have deeper extension with excellence bass attack, decay and sustain. Whereas, the Chopin is all about the sub-bass rumble and boom sensation. Despite that, none of them are domineering. They both reigns their bass region very well. Still, that “enclosed subwoofer” like bassline is PRISM+’s greatest strength which is hard to beat. The Chopin sub-bassy bassline is great. But PRISM bass performance is a ~chef-kiss~

● The Chopin is the more mid-centric set of the two, in a sense that vocals came across being more intimate on stage and having slight better body and weight. For some reason, the PRISM managed to portrays its vocal emotion better. Besides that, the vocals are slightly better textured, airy-er, has a tad more energy with higher voice range. In the Chopin, the voice somewhat has a soft-limiter up in the range which affect female vocal immersion most of the time. Instrument replay such as piano, guitar, flute and violin just have better attack on overall. Note hits sounds slightly more distinct with the PRISM+. The same true can be translated on its vocal as well. The downside is, the PRISM can exhibit a hint of micro-grain on vocal transient, especially on a poorly recorded track which is never an issue on the Chopin. Hence, the Chopin offers a cleaner and safer mid-range while still maintain the naturalness of its timbre.

● Both of them appears to be on the darker-side of spectrum. The PRISM offers slightly better air-extension and brilliance up top which contribute to slightly better treble definition. Instruments like hit-hats, cymbals or even synthetic noise such as electronics have more bite to them. The Chopin treble will come across as the more relax and cleaner of the two which makes it a better set for longer listening session. The PRISM tends to highlights unwanted artifacts such grains or haze. Depending on tracks it may not be present.

● Staging wise, their width and height are nigh identical but the PRISM+ offers slightly more depth. Instrument separation and consistency are about the same. The transition of sound element or sound positioning is definitely sharper and more vivid on the PRISM+. In terms of micro-detail; the bass detail is definitely a step up, mid-range vocals are slightly better as well as the treble. Dynamically, the PRISM+ holds a wider breath of capability, mainly on micro-dynamic bits, making it a more fun and emotional of the two. As for the timbre, despite having greater transient, the PRISM exhibits a slight BA timbre especially on the mid-range region; there is a slight hollowness in terms of vocal body and plus that slight micro-grain on vocal transient do take away some of the points when A/B-ing with the Chopin.

● Driver coherency are top-notch for the both of them. They really did a great job on pairing those drivers together to create a harmonious sound. There is no denying that, the PRISM looks like a piece of jewelry beside the humbly designed Chopin. The craftsmanship is absolutely next level. And because of that, the PRISM is quite heavy which can affect its long-term comfort. The Chopin on the other hand can suffers from a potential fit issue with its peculiar shell design. Thankfully I am not one of them.

● Finally, the price, this is where I think the Chopin murders the PRISM+. Sonically, the Chopin presents a great value next to the PRISM+. The price performance of the Chopin is significantly higher. But hey! If you appreciate the art of craftsmanship and the joy of sound in one package, the Tanchjim PRISM+ is not bad pick. Even after 2 years of ownership, despite all those flaws I mentioned, it still holds a special place in my heart.

◤FINAL THOUGHTS◢
It’s not a set that will impress you with micro-detail or dynamics but the longer you listen to it, the more you value that sheer level of refinement that it provides. There is really not much to fault about this set. From that lens, I must say that I really appreciate the effort of Binary X Gizaudio has put into making the Chopin into such a fine sound while achieving its tuning in mind. The only deal-breaker I can think of is not really the sound quality or the price, but rather the tuning style itself as it falls under the variation of Harman style tuning which is not going to work for all genres. Some would deem it to sound abit too clinical or too safe which is not further than the truth. So, it’s all boils down to preference. Speaking of variation, to my ears, it does sounds like a mini Moondrop Variations which is a big plus. So, if you can’t afford one, get the Chopin instead. You’ll be more than happy to own one. And you will make Timmy happy too XD.

BQEYZ WIND 3 ½ ★★★

▓▒░ SOUND-SIGNATURE ░▒▓
It is some kind of a mild V-shape tuning that has a warmish bassline with a hint of bleed onto the mid-range and a darkish treble with a typical alternating peaks and throughs on roll-off. The mid-range has adequate forwardness in the mix with a stronger upper-mid emphasis. It is quite a well balance sound with decent dynamic-range to carry its tuning.

▓▒░ BASS/LOW-ENDSOUND ░▒▓
● Right of the bat, it is not a very exciting bass to listen to. Dynamic wise it is just lacklustre. And it is not the most well layered and textured bassline.

● The sub-bass sounds like it has a slight roll-off. Any sensation of rumbling, humming or droning fall short just a touch on sustain and vibration feel, which normally resonate with greater extension and transient. Sub-bass boom and sub-drop are clean but not the sharpest. Music ambience has adequate presence to keep your music mildly atmospheric. All of this, could be due to that semi-open back setup which leaks some of that sub-bass attribute.

● The mid-bass presence is seemingly denser in the low-end, it’s rather fat, thick and nicely weighted. While the attack is fast and tight, the impact of kick, slam, punch and thump are not that visceral. It just doesn’t hit as hard or deep as you might expect. Mercifully, despite having a slight bleed onto the lower mid-range, it’s moderately quick decay really helps in preventing the bass from causing unnecessary bloat or mud.

● Truthfully, the bass quantity is never lacking here but it is missing some of that dynamic feel that makes up for a proper bass reproduction. Despite having a bone-conduction and dynamic driver handling the bassline, the end result is not that rewarding. No matter how high I cranked the volume, it just doesn’t cut the mustard, unable to spark my inner softcore bass-head. I could have sworn that even a BLON-03 low-end sounds more characterful and stimulating than this (Despite its loose and warmer nature).

● Preference aside, for people who prefer a tamer, more subdue bass tuning might appreciate this demeanour. Having said that, the bass performance is by no means terrible but it is mediocre at best which is not a bad score in the grand scheme of things. Still, if bass performance is your priority, you might want to look elsewhere. Definitely not for a hardcore bass-head though.

▓▒░ MID-RANGE /VOCAL ░▒▓
● Surprisingly, despite its bassy nature, it is well presented. The overall mid-range and vocal presentation is rather intimate. The leftover mid-bass energy does spill onto this region, giving it’s lower-mid-range and vocal a welcoming fundamental body and warmth. Vocals will come across lush and rich be it male or female.

● One the pursuit of being analytical and musical, the balance is definitely on the musical side of the spectrum. It trades some of the mid-range clarity for euphony. Hence, some of the texture and nuances are smoothed-out.

● Speaking of downside, on many occasions, the vocals can lack in energy and reverberation or should I say, missing that emotion or immersion in its conduct. The voices sounds like it’s got a limiter somewhere, sounding restrained, unable to release their full-range potential. Sometimes, they just don’t sing or scream as they should. Some would associate this with the absence of shout or less energetic upper mid-range but depending on your library and preference, it may not be an issue.

● In correlation to that, the transient attack across the mid-range can sound a tad compressed despite having good note weight and natural decay. The initial note hits have more rounded edge to them, lacking in incisiveness ever so slightly when trying to reproduce instrument like piano, violin, guitar and flute.

● Having said that, the vocals and instrument still come across as natural (but not the truest) and safe for the most part. It’s got good tolerance to sibilance and shout with just a hint of haziness/micro-grain on vocal when your tracks exhibit those poor artifacts.

▓▒░ TREBLE/HIGHS ░▒▓
● The treble however, while being inoffensive, it leans toward the darker-side of the scale. For non-treble-head out there, the treble response offers more than enough sparkle and brilliance with adequate air extension to complete both ends of spectrum.

● The treble is not the most even in response but throughout the assessment there is hardly any hotness or distracting peaks or dips is heard. The transient attack is again fast and smooth with precise decay which are alright for a safe hi-hats and cymbal strikes replay. It could use with a bit more bite for added sizzle and shimmer, especially for electronic music.

● It is not going to be the most well define treble in its class as the treble clarity and transparency are mostly average. This level of treble quality may not impress a true treble-head but will definitely satisfy those treble-sensitive or casual listeners as there are no major flaws that could hinder their overall experience.

✧ ════ •TECHNICAL PERFORMANCE• ════ ✧
The STAGE of the Wind is quite unique, it sounds intimate but at the same time it feels wide and open, I believe it’s due to that semi-open back system? Maybe. Vocal positioning is just about right thanks to the depth of the stage that it provides. As for SPATIAL CUES, it is precise but not pin-point sharp.

INSTRUMENT SEPARATION is not its strongest point. It can sound abit congest on busier tracks. It just doesn’t have enough speed to keep on busy passages which is a common flaw of a dynamic driver. But is definitely one of the better I’ve heard.

DETAIL HANDLING is not that outstanding either. It pretty much falls in the realm of average which is not surprising. Dynamically, it not the most fun set but it is enjoyable enough to plays with all walks of genres.

One thing it does well is when it comes to naturalness of TIMBRE. It has that classic dynamic timbre which brings an organic tone to your music. Every element has good body, good note-weight, natural and smooth decay with a rounded attack definition. None of that hollowness, sharpness or metallic sheen on transient.

The CROSS-OVERS between the 10MM LCP dynamic driver and the coil bone-conduction are just sublime. There is hardly any timbre contrast and driver flex is heard.

~SHORT COMPARISON~
TIGERISM OCTAVE X SPINFIT CP100 (M)
The 1st thing you’ll is the Octave has better sound isolation. This is when you’ll that the Wind semi-open back system is actually doing something to the sound. The Octave will come across as the more V-shaped set of the two. The bass presence is greater with better transient but the Wind offers slightly better quality. It is better textured. The mid-range/vocals definitely sound more recessed and the resolution is a tad lower vs the Wind. The Octave treble-extension is seemingly weaker. The air presence is almost non-existent. The peaks resonate an octave higher and the treble detail is a lot less. As for the technical performance it is definitely a step behind the Wind which is very apparent on busier tracks. Even if cost half the price of the Wind. Its technical performance is very weak. Having said that, I would save up and just go for the Winter. That is how far I’d avoid the Octave after listening to the Wind. Both are undeniably overpriced but between the two, the Wind is better value despite double the price tag.

◤FINAL THOUGHTS◢
All and all, it is not bad set. It is the definition of good enough. I personally don’t think it will stand the test of time. Especially, when competition is very tough on this price point. If it were my own money, I’d stick with Thieaudio Elixir x Nicehck BlackCat or 7hz Timeless x Kinera Leyding. Those two combos are something else. It will run rings around BQEYZ Wind. Or if you want to stick with BQEYZ brand, you could opt for its older brother, the Winter or the Winter Ultra. It’s more fun and has more solid technical performance. So yeah, food for thoughts.

[MY PERSONAL HEAD-FI GRADING]
1 ★ - Appalling! Please Avoid This!
2 ★★ Subpar Offering, There Are Better Options Out There!

4 ★★★★ Not Perfect But Solid Choice ! This Should Be In Your Shortlist.
5 ★★★★★ Class Leading! You Should Go Right Ahead & Buy One!

YANYIN CANON II 4 ★★★★

SOUND-SIGNATURE:
The Canon II follows the suit of being neutral with a bass-boost. Depending on the tuning switches, the amount bass-boost can be altered slightly. The Canon II has great extension on both ends while giving its mid-range/vocals a slight focus. The overall sound is very well balance yet natural that is laid-back and pleasant to the tone.

BASS/LOW-END
The bassline is best describe as soft, thick, smooth, laid-back and not overly forward that is slightly biased towards mid-bass over sub-bass.

The sub-bass has adequate extension and density but the transient is not going to be the sharpest nor the tightest in definition. As a result, the rumbling texture can be perceived as quite blurry, almost muddy at time as it tends to lingers just a tad too long for a bassy tracks. The teasing of echoes and reverbs allows it to recapture the immersion of music ambience.

The mid-bass presence is rather thick with the attack being fast and soft at the same time. Due to the narrower amplitude of attack, any sensation of kick, slam, punch and thump just sounds abit too woolly, lacking physicality on impact. Percussion instrument that lies in this region like bass guitar, kick drums, drum snare are most likely not going to have a satisfying replay.

Ghetto bass replay has sufficient elasticity/re-bound rate while bass-drop remain clean and smooth. One thing to note that there are times when the mid-bass can get a tad too boomy which can be mitigate with the switch (1) turned down. The trade-off is the low-end will sound leaner with clearer and cleaner mid-range.

All of which contributed to an average level of bass detailing and dynamics which might not impress a true bass-head. Having said that, those flaws are mostly just nit-picks. In reality, it is not that appalling as to bring detriment to your music experience.

Those who prefer a non-aggressive bass reproduction might find it attractive. To be fair, bass performance was never been its no. 1 priority especially, when considering its tuning approach. If bass quality is what you’re after, its best to look elsewhere.

MID-RANGE/VOCAL
It is quite the mid-centric set. Regardless of tracks, the mid-range/vocal elements were given a good spotlight as if they have their own dedicated spaces to shine. Still, it is not a vocal specialist per se. It is not the intimate or forward type of mid-range/vocals but it is not overly recessed which took a neutral positioning and centred image on stage. It does trade some of the vocal clarity for added euphony. Micro-contrast could be better but it is not severely lacking.

The rendition of male and female vocals offers relatively equal performance with good voice texturing and reverb. Vocals overall sounded lush and rich which is truly rewarding on male vocals. However, this tuning is not that ideal for some female vocal or any artist that lives in the higher octave. They can sound abit too thick and husky at times. And in addition to that, the polite upper-mids overtone tends limits the higher range of vocal, making them unable to scream or sing to the fullest. The upside is, it makes out to be a proper “anti-shout” set.

To the contrary, it can take away some of that engagement or emotion from a singer. Speaking of emotion, the attack on some instruments is rather gentle especially on strings/guitar plucks, piano hits and violin strums. The note-hits lack distinction just a tad on replay.

On some instances, there is a smidge of grain on vocal transient, specifically on the trailing-end of vocals. If your music exhibits this low-fi artifact, it is going to translate that to some degree.

Despite the setbacks, this sort of mid-range tuning is very likeable if you prefer a more relax presentation that is not overly dull on dynamics.

TREBLE/HIGHS
Just like it's mid-range, the treble complexion underpins the same “safe or inoffensive” behavior. Yet, it still offers a well-extended treble which is nigh perfect for the tuning. The air presence is just about right to provide listeners with adequate sense of openness to the stage.

The treble brightness was never lacking in the first place. However, the main issue is, the treble is severely lacking in terms of bite. The notes although, they have good level of sustain with precise decay, the attack is considered blunted almost. The micro-nuances and texturing are overly smoothed-out, losing its crispy touch which trimmed some of that treble definition. This make’s people perceive it as dark despite having great-extension up top. The cymbal strikes and hit-hats splash do loose some of those metallic edges while electric-guitar or synthetic noise/electronics zings and shimmering just sounded dull overall.

Those treble sensitive people might appreciate this approach but treble-heads might disappoint. Having said that, it has great sibilance control, zero hotness with minimal peaks and troughs, regardless of listening volume. There is a slight micro-grain or haziness on electric-guitar replay which is only apparent on higher volume.

In terms of sheer treble refinement, there’s no major defect other than nit-picks here and there. Sadly, it is not the most well-define treble in its class with its clarity and transparency being average by todays standard. It is by no means terrible but acceptable when all things considered.

There you have it; a smooth, gentle, non-fatiguing treble response that is great for a long listening session.

TECHNICAL PERFORMANCE:
- The overall sound-field of the Canon II is above average. The stage plays more width with good depth and headroom. The vocals/mid-range took a neutral positioning that is neither too distant or forward. The vocal is well-centralized but it tends to blend with the background elements as it doesn’t stand out that much on stage. The stereo-imaging between channels is precise but not the sharpest in class.

- Instrument separation and layering on the Canon II is rather solid. Thanks to the spacious stage, every instrument has adequate spaces between them. The background is not the darkest hence the separated elements may not have the clearest-cut. However, the borders of each element of sound starts to get blurry just a tad on busier tracks.

- Detail retrieval could be better given it’s $380USD price tag. Macro detail is solid but micro detail is slightly behind its main competitor. Sure, it is not a detail-monster but it should be more than adequate for most listeners. Dynamically, it is rather laid-back but not too dull to a point it become soulless.

- For A hybrid setup, the timbral approach of the Canon II is quite natural but it is the not truest to life. It is not that it is lacking note-weight but rather, the transient is on the softer side. The gentle nature of its attack takes away some of the note definition that gives those instrument that dynamic feel or sense of realism on replay. Still, the BA timbre is kept minimal with pleasing tonality throughout the spectrum.

- The cross-over between drivers are very well executed, resulting with a cohesive sound for a multi-driver setup. The timbre contrast within the tri-frequency is very low to detect without paying attention. And there is no driver-flex is heard.

TUNING OPTIONS: Switch (1) – UP or DOWN and Switch (2) – UP or DOWN
DOWN-DOWN – Lean bass, least boomy , has the best mids to treble clarity, most open sounding.
DOWN-UP/ UP-DOWN – The best balance of everything. [Personal Pick] [As tested UP-DOWN ]
UP:UP – The highest bass-boost but lacks control. It gets too boomy & muddy, smearing mid-range and nerfing the treble brilliance a little.

" SYNERGY, VOL.SCALING, POTENTIAL TWEAKS "

- DAC/AMP: The good thing about the Canon II is it’s very easy to drive and not very source picky to achieve a good level of fidelity. Of course, it will scale with better implemented DAC/AMP. No question. To me, the Canon II is best paired with something that is neutral-bright Like the Tanchjim SPACE for example. It does liven the treble a tad while giving it’s a low-end a tighter response. If you find it to sound boring, it is best to pair it with something that is more coloured, vibrant or energetic. In short, the Canon II is not that source picky but quite reactive to different pairing!

- EARTIPS: With the wrong eartips it’s either going to sound too boomy or lean. After plenty of tip-roll, I find the Spinfit CP100 to fit it best. It gives is the bass better control and body with enhancing the mid-range/vocal forwardness just a tad.

- CABLE: The stock cable is very good. There is no need to change to a better one. Sonic wise, I find it had good balance between crisp and smoothness. It is light and non-microphonics which is great. If you’re trying to tweak it, I would recommend a pure silver with graphene mixture cable which quite expensive versus a silver-platted copper wire. But it will definitely improve some of its transient, giving instrument and vocals more texture and crisp that is missing from the stock cable. If you feel the bass is abit too loose, it is best to swap to copper cable for added bass control and presence.

- VOLUME SCALING: Thanks to its well-balance tuning, it does scale very well with volume. You can pretty much crank the volume quite high. However, when the volume gets higher the the bass muddiness starts to get more apparent. If you’re used to a proper low-end, this might annoys you.

~ SHORT COMPARISON ~

EPZ 530 x EPZ CANARI x No-Brand 2 Flange (M)

Right off the bat, the stage of the 530 is slightly narrower and not as tall but in terms of depth they’re nigh identical. In terms of instrument separation, the 530 may not sound as spacious as the Canon II, the gap between instruments aren’t as big. But the 530 has greater consistency on maintaining the borders of each element of sound. It is very apparent on busy passages. And the transition of sound between channel is noticeably more vivid with the 530.

The overall timbre of the Canon II will come across as the more natural and pleasant of the two. The overall micro-detail on the 530 is definitely a step up. Dynamic wise, it is more energetic especially, on the treble region.

The treble has greater extension. It sounded crispier and livelier up top. The 530 may suffers from a slight sharpness and sibilance. And get fatiguing on higher volume.

The mid-range and vocal of the 530 is more intimate and expressive. It’s airy-er and has greater transparency, giving its vocals a better leading surface of texture but the Canon II will come across as the more mid-focus of the two as the bass and treble took a step back in mix. The vocals on the Canon II have that warm reverb, sweet and pleasant tonality to the sound which makes it very soothing to listen to. Having said that, some would be deem Canon II to be abit too safe and not as soulful which is not further than the truth.

As for the bass, both of them are rather mid-bassy and soft on their attack. The 530 BA bass may not have that DD sub-bass rumble of the Canon II but the 530 has better control over its bassline whereas the Canon II can get a tad boomy at times.

The 530 is trickier to drive as it is very picky too source and tips. You’ll be surprise how different it can sound on different setup. Meanwhile the Canon II is much more hassle free to achieve good fidelity. The truth is, they both are very different in what they’re trying to be. In fact, they complement each other very well.

The Canon II remains to be the one to pick if you’re after a more natural, relaxing, smooth with vocal focus in mind. But if you value micro-detail, treble extension, and engagement the 530 is an easy pick.

FINAL THOUGHTS.
The Yanyin Canon II is not a set that will wow you from the get-go. It is a set that will crawl under your skin, the longer you spend time with it. It is not a set that you use to have fun it. It is a set for people who appreciate a relax, well-balance and pleasant sound. I’ve owned a set like the EPZ 530 and the 7hz Timeless. Those sets will impress you the moment you hear it but it gets fatiguing the longer you listen to it. On a long tiring day, I see myself gravitates towards the Canon II more than any of the sets that I’ve own. There is no denying that from a technical standpoint, it is not really that groundbreaking. And it has plenty of setbacks that can irks people. I remember vividly not liking the Canon II that much during my 1st hour of assessment. When dissecting the elements of tri-frequency one by one, I have come across with a lot of minor flaws. But when everything it put back together, it kind of worked. Those flaws become character and I started to understand what it is trying to be. There is something about the overall tonal balance and timbral approach that is very soothing to the ears. It is just so musical to listen to especially on a slow, vocal-centric/acoustic tracks. In that sense, it does it brilliantly. Now that, my time for the tour has come to an end. I am going to miss it genuinely. It's a set that I would love to add to my collection someday. With that being said, if you love this sort of sound-signature, it gets a solid recommendation from me!

I didn't find all these criticisms when listening to the Canon, it is more relaxed but I prefer it to listening to an IEM that gives me half an hour of listening, this is not listening to quality music I would say, you have to appreciate it and not suffer to hear the details etc, I think it's an exaggeration to look for the most crystal clear and detailed sound possible, as I listen more to Metal it fits perfectly for me because it allows me to listen for hours and have fun and I don't agree with its bass not having that strength and tightness, they They are fast and accompany bass drums easily and I have already done several tests using different types of styles within what I listen to from death metal, thrash and power, my only complaint would be that the stage on the side is not wide but has a lot of depth.

This review seems unusually more picky compared to most of the reviews I've read on here. Not that that's bad or anything, it's good to have high standards, but idk I'm just getting the feeling you're listing cons just for the sake of listing cons. It's better to build an opinion that goes in one direction instead of several directions.

Also take what I said with a grain of salt. I don't intend on changing your review style. You do what you think is best.

Like your review format very much. Only addition I would make is to make general comparisons to perhaps 2-3 more IEMs... not many have the EPZ530... more had the Timeless 7Hz so that helped.
