The bass on the BQEYZ Wind IEM is super impressive. It's got depth, definition, and a punchy presence that you can feel. The dynamic driver gives you a rumble that goes deep into the sub-bass range, and the mid-bass section has a solid thud that's quick and organic just like real music. And best of all, the bass stays controlled and doesn't get bloated, so you get a balanced and satisfying sound. Even though it's not for extreme bassheads, it's still got enough oomph to stand out as one of the best features without getting in the way of the mids.



The BQEYZ Wind IEM's midrange is fantastic! It has a natural and alive sound with a perfect balance of high and low frequencies that produce crystal-clear sounds. Both vocals and instruments are spot-on and sound precise, detailed, and full of life.



The treble response is detailed and smooth but not too intense, making it enjoyable to listen to different types of music without any harshness. The open-back design helps to create a broad and immersive soundstage, which is pretty cool. It's got accurate imaging and noticeable note weight, too.



To sum it up, the BQEYZ Wind IEM is a dope option for music lovers who enjoy different genres. It's got a balanced sound with deep bass, detailed midrange, and lively treble, which makes it perfect for an engaging listening experience. Plus, the midrange is super and forward, making the whole thing even more enjoyable. So if you're into quality and versatility in your audio gear, I highly recommend you go for the BQEYZ Wind.

+Wide Open Headstage:
Since the Wind is open-backed, notes can decay naturally and infinitely without a sense of hitting and bouncing off the backplate. This adds to the timbre decay which ends up being so natural that you've never heard it. It has a circular headstage where it is as tall as it is wide, and it is very wide with quite good depth.
What is more, it is incredibly open-sounding where you can't sense an obvious end to the stage, beating out even full-sized headphones such as HD650 or Hifiman Ananda in terms of how notes decay outwards. At the same time, it is very intimate where voices come really close to you, singing exclusively for you, the listener.

+Bone Conduction Adding Audible Tactility In Bass And Mids:
Yeppers, this bone conducation works wonders. If you place your thumbs on the surface of where the bone conduction operates throught he shell, you can actually legitimately feel the vibration. How this is expressed during musical replay during actual listening is like it's adding a subtle layer on the replay that is perfectly synced to the dynamic driver, humming along nicely with what is happening in the bass and mids. It makes everything in the bass and mids a little denser, more physical, more tactile.

+Outstandingly Natural Timbre:
As mentioned before, timbre is outstanding. Each note has proper weight thanks to the BC driver and the open-backed nature allows for uninhibited infinite ripple decay of the notes.
What you end up with are notes that you experience like this in your head:



+Reverberation:
The BC driver together with the open-back infuses each note with a reverb that also aids the sensation of the note expanding forever until it naturally dissipates, like a drop in water.

+Higher Notes Of Vocals:
The high notes of vocals or instruments is one of BQEYZ specialties. There is a delicious vibrancy there around 2-3kHz that makes the crystalline aspect of voices really shine through and touch you. Singers who are belting out sound super dynamic and punch through all the way to your dopamine system. Female vocals operate in these frequencies more often than male vocals, so they benefit more.

+Midrange Transparency:
Really great transparency in the mid-range. It sounds very dynamic, powerful, transparent, pure. This allows you to connect to the performance and hear the music in layers.

+All-Encompassing Bass Presence:
A huge bass presence thanks to the BC driver vibrating. It's huge not in terms of depth or volume, although the Wind is no slouch in those areas, but rather; it's huge in sheer size. It fills the entire headstage with bass. It's like your head is inside the guitar while it's strumming along. This calls for powerful sources that tighten up the bass while adding a little extension ontop for best synergy. The Wind is all about being inside each note as opposed to standing at a distance and seeing the separation between each note.


-Bright-Tilted Tone:
Now for the negatives and the first one is a nitpick. The Wind has, despite its great BC driver adding substance to the bass and mids, a slight bright tilt to its tonal balance.
The LCP dynamic driver is maximized for upper-midrange purity, but becomes lean in the lower mids in the pursuit of transparency. The BC driver does fill
in the sound to a good degree, but doesn't quite compensate all the way to say it has a perfect tonal balance.

-Diffuse Imaging:
The notes are so large, because they are not contained by treble contours. This makes the imaging diffuse and unspecified, so this is not a set
for analyzing exactly how the mix has been mastered and put together. Rather, you enjoy the very center of the note first, spewing forth to the forefront.

-Non-Articulate Treble:
One of the most immediate things you notice about the Wind is its absence of treble. What I mean is, it gives such a close inspection of each note that you could say you're inside of it and you lose the perspective of the contour of each note. This hurts the sense of sensing separation and location of the treble. You hear treble, but your mind can't pin point where "on the instrument" it is.


-Needs A Nozzle Filter To Achieve Tone Balance & Bring Treble Peaks Down:
I rectify the bright tonal balance by adding a nozzle filter which tames the peaks in the treble, giving it a perceived warmer and more refined sound. After doing this, it becomes almost perfect according to my preferences. By adding the filter, you effectively negate the first negative point about having a bright-tilted tone.

Conclusion:
The Wind is a special IEM that sounds like no other IEM that I have heard. It delivers a unique and addictive perspective to music that is only enabled by its BC driver and open-back nature. I consider it the best IEM under $500 and it is one of my favourite IEMS ever, all things considered. At $200, it is a must have for anyone, either as your main set or as a reference in terms of natural note decay.

BQEYZ Wind

Thanks to BQEYZ and @gadgetgod for providing me with an opportunity to audition and review the BQEYZ Wind.

Introduction

BQEYZ as a brand has been in the IEM game for a long time and doesn’t need any introduction per se. Adding to their weather collection of IEMs such as Summer, Winter, Spring, Spring 2, Autumn, and Winter Ultra, is their latest offering called Wind. The wind is a hybrid IEM that combines a Dynamic driver (DD) with a bone conduction driver (BCD). The wind has a special dual cavity LCP DD coupled with a self-developed 10mm bass and medium-frequency bone conduction driver. As per BQEYZ, the copper BC shell, coupled with a high-toughness steel vibrating reed, ensures durability and performance. The earpieces are lightweight and are created using German 5-axis CNC aluminum alloy cutting technology. They look quite like the earpieces of FiiO FH9, albeit smaller and lighter. The unit I received was a blue unit that came with a 4.4mm balanced cable. The stock cable is a silver-plated copper cable and is quite good in terms of build quality. Overall, the IEM and the cable look quite good and seem to be durable.

The IEM came with a box of 6 pairs of tips in S, M, and L for reference tuning and atmospheric tuning. For this review, I used the BQEYZ wind with Flare Audio’s Audiophile Memory foam ear tips.



Sound Impressions

The BQEYZ wind has quite a strong bass presence, although not quite to the level that bass heads would prefer, but I was quite happy with the bass response of the IEM. The bass doesn’t bleed into the mids and is quite powerful in terms of slam. There is a good amount of rumble and sufficient mid bass presence as well. The bass is easily one of the highlights of the Wind.

The mids are quite thick and have a fair amount of detail. In terms of weight, the mids have a good amount of heft and don’t seem too feeble or light. Again, the BCD adds a sense of liveliness to the mids that makes them feel and sound lifelike.

The IEM falls short in terms of treble extensions, but given the warm tonality, the treble complements the overall sound well. There is a decent amount of air and plenty of details, but the treble is not too sparkly and lacks some sheen.



In terms of technicalities, the IEM has a wide soundstage with a decent amount of depth. The stereo image is crisp, and separation is good. Given the price range, the technical performance of the IEM doesn’t disappoint.

Conclusion

The BQEYZ Wind is a warm-sounding IEM that is very comfortable in terms of the build. The IEM seems very durable and can make a good daily driver. The bass and mids are the highlight of the IEM. The treble, although well-detailed, lacks sparkle.



All in all, the Wind is a good IEM for those who prefer warm sound and would like to get a taste of BCD without having to break the bank.

Review Of The BQEYZ Wind ​

Introduction​

As I have stated previously, BQEYZ is an electroacoustic production firm that surprises its followers with its own inventions and execution rather than going along with the crowd. And because of this, I have always liked them every time I have reviewed one of their products. I respect and admire the company for paying attention to its followers and consumers and delivering. I am eager to examine their just launched new IEM, the Wind, which makes use of their newly designed driver configuration. However, before I do, there are a few things I would want to make clear.

Disclaimer​

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

Specification​

A 10mm LCP composite diaphragm dual cavity dynamic driver and a 10mm bone conduction driver make up the hybrid driver arrangement used in the Wind. The bone conduction driver, which handles medium and low frequencies, is a self-developed coil bone conduction driver. The aluminum alloy used to make the shells has a semi-open design, with open cavities designed on the faceplate to allow air to pass through. Regarding fit and comfort, I had no problems wearing them, however using them for more than two to three hours did get tiresome.The Wind single crystal copper plated silver wire that comes with the cable includes a 4.4mm termination straight plug on one side and two pin connections on the other. Additional accessories that come with the device are a carrying case, a 3.5mm jack adaptor, and an assortment of eartips in various sizes and styles. Regarding the technical details, the sensitivity is 113dB and the impedance spans from 33 to 100 ohms. The range of the frequency response is 5 Hz to 40 kHz.

Sound​

With a strong bass and an upbeat feeling in the higher frequencies, the Wind's sound tends to be more V-shaped. The Wind, in my opinion, has a nice upper mid range intensity that provides strong clarity over the elements and makes for a pleasant listen. It's really encouraging that other IEMs that are priced similarly to these have had different responses from customers, since it breaks the monotonous loop of adopting the same goal that all businesses pursue. These sound similar to the EA1000, in my opinion, but not quite the same. I mean, the way the midrange and treble are handled feels like it was tuned for the EA1000 by SIMGOT. I think this is not the most detailed out there, even if I think the driver used in it is truly of a very high caliber. In technological terms, it sounds nearly exactly like the DUNU Falcon Ultra, but more on it later. To learn more, let's explore the sound more thoroughly.

Treble​

The treble response is very composite, but it doesn't highlight any parts that, in my opinion, sound disagreeable or strange. If anything, they don't make sense, as if they were done on purpose. That's not new, though, because I've heard similar things about other BQEYZ IEMs, which are essentially tuned in-house and have a devoted fan base. To be more precise, I feel that the upper treble section sounds a little wrong. It sounds like the accentuated part is supposed to provide an impression of space and airiness, but neither the voices nor the instruments are meant to sound broader and more "complete." However, I think it's really extended, which makes some of the responses sound agile and vibrant, which makes it more alluring and sizzling. Every sound that you hear has a more forward-sounding, composite lower treble section. This area really has a highly fluid and active reaction. Together with the instrumentation, the voices sound upbeat and forward, with just the right amount of clarity in the notes. As a result, the treble region's overall appearance is vibrant, interesting, and energizing.

Mid Range​

As we approach the mid range, I have to say that it is alluring and exudes the same vitality as the higher frequencies. With the exception of being more comprehensive and resolved, the reaction is very similar to the Falcon Ultra. Since there is a good tonal balance between the upper and lower mid range, the forwardness doesn't introduce any objectionable qualities. Thanks to the lower emphasize and resonant warmth, the upper mid range sounds more forward and clear than any other range, enabling a vibrant and lively response that avoids sounding metallic or harsh. While the instrumentation enhance the voice, the vocals take a more upfront approach. The notes have weight and a thick, solid depth, while the lower mid range adds just the proper amount of warmth. A positive indicator is the muttering effect created by the singers and instruments. Additionally, the BC helps to level off the occasional natural decay of notes in the lower frequency, contributing to the clean sound. As a result, the mid range area is presented in a forward, colorful, and tonally pleasing manner overall.

Bass​

This bass doesn't sound bloated or overbearing; instead, it rumbles and yields a forceful reaction. The notes are of excellent quality since they operate quickly, allowing for a regulated and orderly reaction. The sub bass range, which excels at handling the deep, rumbling bass, is where the emphasis resides. The rumbling sensation adds to the enjoyment of this bass, and the punches are strong. The mid bass is present enough to provide the smash and thud a solid, controlled feel. The attack comes on quickly, yet the decay seems organic—that is, a slower decay gets it almost exactly like actual music. Although the notes aren't very good, they are sufficient to give it a sophisticated, almost exact sound. Overall, the bass area is presented in a controlled, punchy, and rumbly manner.

Technical Performance​

Regarding the technical specifications, I believe the Wind performs well in comparison to comparable IEMs in this price range, such as the Falcon Ultra, EA1000, Quartet, etc. However, in my opinion, it is a little lacking in that technical skill. The EA1000 is still technologically advanced, in my opinion. Let's get into further depth.

​

Soundstage, Sound Imaging & Separation​

Although the stage's vastness and depth contribute to its spaciousness, it falls short of its full potential in terms of sound quality. While the image is crisp and clear, it might have been even better, similar to the EA1000. The note separation is noticeable and far enough away to give me peace of mind while attempting to locate the source of the sound.

Speed & Resolution​

The resolution is excellent, allowing both macro and micro features to be seen well, yet the minute details become somewhat lost in complicated tracks. Though everyone has a different interpretation, the notes' unexpectedly quick onset and delayed decline put them in the ballpark of a genuine reaction.

Sound Impressions ​

Sources​

Sony WM1A - The response seems as though additional width and depth have been added to the mix while maintaining a forward-projecting midrange and a better extended treble while listening to Wind with WM1A. In actuality, the details are more illuminating while maintaining clarity. At some moments, the instruments and voice both seem a little bit larger. The bass seems a touch muted, which gives the impression that it is larger and more expansive overall.

Tempotec V6 - In comparison to the WM1A, the response seems sharper and more closed while listening to Wind via Tempotec. The midrange maintains it sounding lively and expressive while the treble makes it seem more filled. Conversely, the bass has more control and sounds meaner and more forceful.

Aful SnowyNIght - When listening to Wind with Snowynight, the mid range is more subdued and has better placement, and the response seems deeper and more layered. Finding the energy in the high treble and producing a better-executed extension is made simpler by the stage surrounding. The bass, which is between 100 and 200 dB, sounds more emphasized in the response because the lower notes pound more prominently. Because of the improved energy balance, a linear response is possible.

Colorfly CDA-M2 - When listening to Wind with M2, the response is nearly identical to Snowy Night, but it sounds much more balanced, with a better sense of spaciousness and placement along with a bit of warmth. When compared to Snowynight, the treble sounds more expansive and the intensity is more subdued, especially in the 2-3k range. Rather than punchier and more precise, the bass seems warmer.

Conclusion​

Ultimately, I found the reaction to be a unique experience and can attest to their sincere efforts in implementing their drivers, which are tuned to sound incredibly fantastic for the price. I heartily suggest these to anyone who like BQEYZ in house music, as they are sure to please.

Thanks to Hifigo and gadgetgod for organising the BQEYZ Wind review tour.

Overview
BQEYZ was one the earlier iem brands to sport multiple drivers that was a fan favorite for a very long time, with the KC2. I had owned the KC2 for a long time too for providing a very nicely balanced and rich soundscape. It still has its fan following.

The Wind felt like a spiritual successor to the KC2 in terms of tuning.

The Wind (part of the Weather series of iems) is a hybrid driver iem with a dual cavity dynamic driver, paired with a bone conduction driver. This combination made me think that the iems may be a basshead iem. However, this was not the case.

Build
The iem shells are CNCed aluminium alloy that are sturdy and look strong and are unlikely to break in a long time. The shells are lightweight and have a fairly large sized nozzle, but not as big as say the Celest Plutus Beast.

The iems came with a silver colored cable and a selection 6 pairs of tips in S, M and L for reference tuning and atmospheric tuning.

The review unit came without the stock box, hence the accessories were minimal.

Sound impressions
As mentioned previously, the Wind is a warm iem, but not quite basshead level. The bass, while present, is well restrained within its frequency range and do not bleed into the mids.

The mids again are presented nicely, with good detail retrieval and sonic nuances.

The treble, while being a little short on the extension, has plenty of detail for everyday listening.

Overall, the tuning is very reminiscent of the KC2.

In comparison to the Celest Plutus Beast (in a similar price benchmark), the Wind sounds more coherent and clean, with the BC being a bit more controlled in delivering the goods.

Conclusion
In a hotly contested mid budget space, the Wind offers a continuation of the sonic signature that was previously loved in the KC2. If you are looking for the KC2, and cant find one, the Wind is the one to get.

The bone conduction and the bass drivers, while having decent bass, dont seem to overpower the mids and the other frequencies.

P. S. These are some of the best IEMs I've ever had in my life (I'm talking about sound)!

BQEYZ has brought the latest into its weather series of IEMs with the release of the BQEYZ Wind. Things that started with the Spring Season followed great performance in Autumn and winter, and now we have the Wind. An IEM with a unique driver combination featuring a dynamic driver and coil-based bone-conduction driver on each side. I love how BQEYZ always experiments all around and brings products that are great in terms of sonic performance and at the same time, don’t break the bank. It is not the first time BQEYZ is here with a BCD driver, Winter also featured one and I liked the set. Although the BCD driver in the Winter was implemented above the 200Hz mark. In the Wind, they have implemented a 10mm coil-based BCD driver responsible for lower-end and midrange. I got a sample sent my way by BQEYZ themselves, and today I am going to share my review on the same. So let’s get our reading glasses on plug in your favourite IEMs and begin with the review.

Disclaimer:-

BQEYZ sent me the Wind for the purpose of a review tour in India. I will be forwarding the unit ahead to the next reviewer, not being benefitted by them in monetary ways by any means. The unit belongs to them until they let me keep it after the tour. You can buy the BQEYZ Winter from the online retailer(will be adding the HiFiGo link below). It’s a non-affiliated link. At the time of this write-up, the product retails for 239$.

https://hifigo.com/products/bqeyz-wind

Design & Build Quality:-

BQEYZ Wind looks good, really really good. The entire shell is metallic and has a semi-open back grill design. The Blue colour that I have is spectacular, it looks vivid and bright, just the way I personally like. The design of the pair is similar to QDC Tiger which is a premium flagship IEM. The face covers have BQEYZ Wind branding(BQEYZ on one side and Wind on the other). On the inner side, we have the BCD driver, we can see where it is located as it is covered by a separate panel with two screw kinda things. Will add the images below so that you can also have a look at that place. We get a detachable cable with 2-pin connectors and a preferred choice of termination, no swappable plugs here.


Fit and Isolation:-

For any IEM with a BCD driver, Fit plays a crucial role. If the BCD driver doesn’t touch your skin, it won’t work for you. BQEYZ Wind for me is the best fit for their IEMs. Out of Spring 2, Autumn, Topaz, and Winter, the Wind is the one that fits me the best. And the BCD driver also touches my ear, so I can actually feel that bass rumbling hard lol. Although I must add here, the stock tips were not the best fit for me, I am using the BQEYZ Wind with Softears UC eartips. They bring the IEM closer to my ear making the BCD area touch my ear. So I suggest you try different tips and then choose the one that is most comfortable and also helps you to feel the BCD driver.

Driveability:-

BQEYZ Wind does love some extra juice sent her way. Although works well with most sources that I have treated her with including my MacBook Pro, Hidizs S9 Pro Plus, AFUL Snowy Night, Questyle CMA18P, Questyle QP2R, etc. I would suggest using a decent-level USB DAC as a minimum with the set I tested with Questyle CMA18P and QP2R for most of this review.

Sound Quality:-

The unique combination of DD and BCD drivers here on the BQEYZ Wind is implemented nicely. It sounds cohesive as a single unit, the BCD driver produces a strong and slamming lower end just make sure it touches your ear when you wear the set properly. Bass has good reach and definition. It reaches deep in the sub-bass region and produces a good rumble along with a good punch in the mid-bass section as well. The midrange has a clean and crisp presentation. Vocals show good clarity and resolution. The same can be said for the instruments in the midrange. In my experience with their products so far, BQEYZ tunes with an open and detailed midrange section. Instruments such as Piano, Acoustic Guitar, Harmonium and wind instruments such as Trumpets, organ, etc. show amazing details and lovely tones in the midrange section. The overall tone on the Wind is quite natural and lively, Vocals sound full of life, they are well-textured as well.

Treble region is smooth and inoffensive. No harshness or sibilance is present on the Wind yet it received good micro details in the sound. Treble region has good air as well and doesn’t sound congested or intimate for busy tracks such as Billie Jean by MJ. I would personally love a little more energy into the Treble section, but hey where will I put the Simgot EA1000 then? lol. Overall, BQEYZ has treated the pair with an amazing sound tuning, it packs a sound that will complement most genres. I personally tested it with multiple genres including EDM, Hip-Hop, Rock, Pop, Classical, and some regional Bollywood, I never found the BQEYZ Wind to sound lacking at all in any given department. Technically, again I find the BQEYZ Wind to be highly efficient. It has good note weight, accurate imaging, and a wide+Tall soundstage. With its open-back cavity design, the soundstage also has good depth giving a full 3D feel.

BQEYZ Wind’s sound finds a place in my best IEM around 200-300$ price bracket. Heck, it can compete with some IEMs priced above its range(will share my comparison with Tangzu Nezha ahead) and will have some points going there in its favor. For me, BQEYZ Wind is probably the best BQEYZ has offered us so far.

Let’s summarise this review with some basic points.

>Excellent bass, fast, snappy, and deep-reaching.

>Clear and crisp midrange. The vocals sound well-textured and well-detailed.

>Handles even busy tracks easily, nicely executed treble.

>The soundstage has a good 3D feel.

>Excellent Imaging and instrument detailing.

>Instruments also have a decent amount of note-weight.

>Tone and Timbre are simply excellent, smooth and natural.

Some things that I feel could be improved here:-

>Fit, Yes the fit is very good for me. But unless the pair fits you perfectly, you won’t be able to feel the proper bass response of the BQEYZ Wind. So mentioning it for the team.

>Requires a decent amount of power. If you don’t have a decently powerful source, you won’t be able to feel the proper sound of the BQEYZ Wind.

>Treble is too smooth for me, personally I would love a little bit more energy into that section.

Now on to some comparisons.

BQEYZ Wind vs Simgot EA1000:-

Both these IEMs have a dual-driver hybrid configuration. The Wind has a DD+BCD combination while the EA1000 has a DD+PR configuration. Let’s take note of how these two compare.

>EA1000 is more sensitive than the Wind, so easy driveability.

>EA1000 have a tad bit more mid-bass slam and weight. The wind has more refinement and a crispier lower-end definition.

>Wind has a faster and snappier bass response.

>Both the pair have clear midrange, but Wind sounds better definition and slightly more clarity.

>Treble on the EA1000 is on the brighter side. It is more defined and extended. Wind handles a smoother approach in treble. EA1000 might sound offensive to some.

>Wind has a more 3D feel to the soundstage.

BQEYZ Wind vs Oriveti OD200:-

OD200 packs a single dynamic driver setup while the Wind brings a DD+BCD combination. Here’s my take on these two.

>Wind’s bass has more slam and weight to the bass. Oriveti is a little thin in comparison. Both have identical speeds and extensions.

>Oriveti’s midrange is a little thin in comparison, Wind has more weight to the vocals and instruments.

>Both maintain a good treble region with the OD200 presenting more energy, and the Wind presenting a smoother response.

>Wind’s soundstage is more 3D.

BQEYZ Wind vs Tangzu Nezha:-

Nezha the latest flagship from Tangzu packs a multi-BA+PZT hybrid configuration and retails for 400$. Here’s my take on these two.

>Wind definitely has more lower-end presence. It is faster, snappier, and punchier.

>Midrange is the charm of Nezha, Vocals sound really good. Although Nezha have a little BA texture to them and Wind sounds more natural.

>Vocals and midrange on the Nezha is more forward in comparison.

>Treble on the Nezha is more extended, crispier and has a slightly better definition than the Wind.

>Wind has more instrument and vocal weight thanks to the added bass response.

>Soundstage of Wind is more 3D, and is taller.

Final Words:-

BQEYZ Wind is an IEM that brings us a taste of Bone-Conductiuon Drivers in a pocket-friendly price bracket. And they have nailed it with the sound of the Wind. I have been using the set for quite a while now, and never even once have I felt like I should listen to something else. Right from the comfortable fit to the amazing sound, Wind packs it all in a beautiful metallic shell. For around 200$, BQEYZ Wind is one of my top recommendations alongside the Simgot EA1000 and Oriveti OD200. I hope you guys enjoyed reading my review, if you have any questions or queries related to the Wind, feel free to ask me in the comments section below.

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.

DISCLAIMER

I purchased the BQEYZ Wind at a discounted price from Aliexpress.

It can be gotten here: https://www.aliexpress.com/item/1005006042191996.html (no affiliate links).




SPECIFICATIONS

Driver configuration: 10 mm LCP-composite dual-cavity dynamic driver + 10 mm bone conduction driver
Impedance: 38 Ω
Frequency response: 5 Hz - 40 kHz
Sensitivity: 113
Cable: 2-pin, 0.78 mm; single crystal copper-plated silver cable; choice of 2.5 mm, 3.5 mm or 4.4 mm terminals
Tested at $239 USD


ACCESSORIES



Other than the IEM, these are included:
- 1 pair of foam tips
- 3 pairs of "balanced" silicone eartips (S/M/L)
- 3 pairs of "reference" silicone eartips (S/M/L)
- 3 pairs of "atmosphere" silicone eartips (S/M/L)
- Cable
- Cleaning brush
- Carrying case

The accessories are really generous for the price, no complaints here perhaps other than the lack of a modular cable.




A variety of eartips are included. The foam tips come in their own little case, and they provide the best isolation and tame treble (though with a slight compression of soundstage).

3 types of silicone tips are present. The "reference" tips have the widest bore and boost the upper frequencies the most, with an increased soundstage. The "atmosphere" tips have the narrowest bore and provide the greatest bass. Lastly, we have the "balanced" tips, which are a midpoint of the above 2 silicone tips.




A 2-pin single crystal copper-plated silver cable is included. It is very well braided and of sufficient heft. There's a chin cinch for added stability, albeit there's some smattering of microphonics. During ordering, consumers can opt for a 2.5 mm, 3.5 mm or 4.4 mm termination, depending on the source that you use.




To complete the packaging, we have a cleaning brush to remove debris, and a semi-rigid leatherette zipper case. The innards of the case are lined with a velvety material and webbing to protect the contents, whereas externally, it is hardy enough to survive a drop or compression.

The rest of this review was done with the stock cable and stock "balanced" silicone tips. No aftermarket accessories were used, so as not to add any confounders to the sound.


BUILD/COMFORT



The Wind's housings are fashioned from 5-axis CNC-machined aluminum alloy. The earpieces are then sandblasted, undergoing anodized oxidation to give a smooth finish. One can choose between a silver or a blue-hued shell. Build is solid and robust. They come in a teardrop-shaped design with some slits along the shell, to mimic a "wind" motif.

Ergonomics are impeccable - the earpieces are extremely light, with no protrusions on the inner aspect to poke the ears. I did not encounter any discomfort despite using them for marathon listening sessions.



2-pin connectors are always welcome in my book, as I've encountered MMCX failure more often in my IEM journey, especially with frequent cable swaps.




The bone conduction driver is housed on the inner part of the shell (see circles above), and this should ideally contact the concha of the ears to transmit soundwaves and add heft to the lower frequencies. As we will read below, this bone conduction driver is not a gimmick unlike some other purported bone conduction tech in other IEMs where there is no contact with the skull or ears.

The Wind utilizes a semi open-backed design, with multiple vents gracing each earpiece. This is a double-edged sword, as it furnishes a very expansive soundstage, but at the expense of isolation. Thus, the Wind is not the best option for noisy environments - or ironically, in windy places as per its namesake - as the outside noise will get in. One will not be getting good sound as such, and users might even be tempted to jack up the volume to compensate for this, which is detrimental to hearing health in the long-run.

I did not encounter any driver flex on my pair.


DRIVABILITY

I tested the Wind with the following sources:
- Apple dongle
- Cayin RU7
- Fiio K11 DAC/amp
- Fiio KA13 dongle
- Hiby R3 Pro Saber 2022 DAP
- Khadas Tone Board -> Schiit Asgard 3 amp
- Questyle M15 DAC/AMP dongle
- Sony Walkman NW A-55 DAP (Walkman One WM1Z Plus v2 Mod)
- Sony Walkman NW A-55 DAP (Walkman One Neutral Mod)
- Sony Walkman NW WM1A DAP (Walkman One WM1Z Plus v2 Mod)
- Smartphone

This IEM is modestly easy to drive from weaker sources, though you might need amplification for the Wind to truly flourish - juice provides better bass tightness, dynamics and soundstage.


SOUND & TECHNICALITIES


Graph of the BQEYZ Wind via IEC711 coupler. 8 kHz is a coupler peak.

Tonally, the Wind can be described as warm neutral. Although the graph above appears to hint at a neutral bright sound, bear in mind that conventional couplers may not adequately pick up the bone conduction vibrations of the lower frequencies.

This IEM is sub-bass focused. Bass is just north of neutral, but not at legit basshead levels. The sub-bass descends well with a visceral rumble, contributed by the bone conduction tech. On some tracks where the bass hits low, it is almost subwoofer like! The bass is on the nimble side, with no mid-bass bleed, but texturing is not class-leading and may smear slightly.

The Wind will be a great option for midrange-lovers. The lower mids are very transparent and clear, with no big bad bass encroachment. Instruments and vocals are superbly layered and easily pinpointed on the canvas of a dark background. Upper mids are forwards without veering to much to shouty territory, allowing vocals to be showcased without being too fatiguing.

The Wind has moderate treble extension, but isn't a trebleheaded set. While it isn't dark, the amount of sparkle or air might be lacking for trebleheads. Sibilance is kept to a minimum, without much splashiness in cymbals or high hats.



Timbral accuracy is excellent. Woodwinds have an airy tail to notes, brasses have metallic overtones, and strings have their typical bowed signatures heard. Indeed, timbre freaks will have a field day, and this is one of the more natural sounding IEMs I've tried.

The Wind handles technicalities like a breeze. The aforementioned semi-open design contributes to an expansive soundstage in all 3 dimensions. The excellent layering and instrument separation also contributes to a spacious soundscape, with zero claustrophobia. Imaging is acceptable for the price, and micro-details are more than decent, considering it isn't a very treble-boosted set.


COMPARISONS

Comparisons were made with gear residing around the $200 USD range.




BQEYZ Winter

The Winter is the predecessor in BQEYZ's stable, and also utilizes a DD + BC setup. However, the Winter's BC driver supposedly handles the upper frequencies, in contrast to the Wind's configuration.

The Winter is lighter in the bass, with greater treble extension. However, the Winter can come across as more fatiguing, with sibilance present. The Winter has a more metallic timbre, but it has slightly better micro-detailing and imaging, though the Wind has a larger soundstage.


Binary X Gizaudio - Chopin

The Chopin is a U-shaped hybrid. The Chopin is sub-bass focused, but has a huge mid-bass scoop out, which results in an anemic lower mids/mid-bass. Music sounds sterile with a thinner note weight as such, resulting in a more "boring" sound compared to the emotional Wind.

The Chopin has BA timbre, and sounds less natural in this department. The Chopin has a more extended treble, though with a bit more sibilance.

In technicalities, the Chopin has a faster and cleaner bass, with better imaging and micro-details. However, it has poorer soundstage compared to the Wind.

Of note, the Chopin has a low impedance of 12 ohms, and it may not synergize well with sources with high output impedance, based on the rules of eights. Anything higher than 1.5 ohms in the source output impedance might skew the frequency response. The Wind is less source agnostic, but requires more power to drive.

The Chopin has a more awkward fit and isn't as ergonomic.


AFUL Performer 5

The Performer 5 is a U-shaped pair. It doesn't fare well in bass texturing too, but has even worse mid-bass bleed with a slower bass. The midrange isn't as transparent, with an artificial BA timbre noted on the Performer 5.

Technicalities are a step behind on the Performer 5. It has inferior soundstage, imaging and instrument separation.


CONCLUSIONS

In the Wind, BQEYZ has created a literal breath of fresh air in the highly-competitive CHIFI scene. The Wind does not need to resort to the hackneyed overused party tricks like Harman curves or waifus to get its sound across. Listeners will be greeted by a very organic sounding set, with superb tonal balance.

The warm neutral signature, with a sub-woofer like bass (courtesy of the bone conduction tech), is pretty unique, coupled with a transparent midrange to die for.

Granted, it isn't the most sparkly or treble-boosted in tuning, and perhaps extreme trebleheads might need to look elsewhere. However, most others (including treble sensitive folk) will appreciate the treble dosing, balancing a fine line of resolution without fatigue.

Additionally, accessories, build and ergonomics are exemplary, and technical chops are also solid. The open-back design confers a great soundstage, and layering is a highlight on a dark background. This open-back concept does sadly contribute to penalties in isolation, and arguably the Wind is not the best IEM to bring to a noisy environment.

Other nitpicks are a bass lacking in texture, and the somewhat power-hungry requirements. While it can be powered off weak sources, one is probably not getting the optimal sonics that way, and amplification is highly recommended.

To conclude, the Wind is one of the better purchases I've made this year, I really appreciate the special melding of an organic timbre, a neutralish signature with the positive quirks of a bone conduction driver, and the dependable technicalities. It is a wind of change for the better, and is something noteworthy amongst the banal weekly Harmanish releases that don't give any value-add.

Introduction

And BQYEZ continues to evolve. Now it has presented its new Weather series, whose models will be Wind, Cloud, Rain and Mist. The first one is already here: it's the Wind. And, well, it seems to have a lot in common with its successful previous model Winter. Yes, it's similar in name and it also uses a bone conduction driver. Although in the Winter, this was piezoelectric and dedicated to high frequencies. In the case of the Wind, the BC driver is dedicated to reproducing the low and mid frequencies, by means of a self-developed 10mm driver. Now, BQEYZ has developed a BC driver with a copper housing and a high-strength steel vibrating reed. It is located on the inner side of the capsule, vibrating directly towards the outside of the headphone housing. In this way, bass and mid-frequency sounds are transmitted directly to the ear cartilage and the surrounding area. The Wind also uses a dual-cavity dynamic driver with a 10mm composite LCP diaphragm. The metal capsule has been made from lightweight aluminium alloy using a German 5-axis CNC. Meanwhile, the surface has been finished using sandblasting, anodised oxidation and hollow-cutting technologies and is corrosion resistant. Finally, the capsules are accompanied by a complete set of accessories, each of which will be described in the following review, as well as, of course, the sound of this great model.



Specifications

• Driver Type: 10mm dual cavity dynamic driver with 10mm LCP composite diaphragm. 10mm bone conduction driver with copper housing and high strength steel vibrating reed.
• Frequency Response: 5Hz-40kHz.
• Sensitivity: 113dB
• Impedance: 38Ω
• Jack Connector: Choice of BAL 2.5mm, SE 3.5mm and BAL 4.4mm.
• Capsule Connection Type: 2Pin 0.78mm.
• Cable Length: 1.2m.
• Cable Composition: Silver plated monocrystalline copper wire.

Packaging

The BQEYZ Wind comes in a medium sized light violet-blue box. Its dimensions are 158x119x54mm. In the centre is the wind symbol (fend). Below, vertically, the model name. At the top left, the name of the brand, in small letters. At the bottom of the box the description of the model. On the back are the specifications, in Chinese and English, the contents and the brand name, as well as the certifications held by the product. After removing the outer cardboard, a textured black box appears vertically, with the brand's lettering in silver ink in the centre, as well as the slogan, at the base. It opens like a book and a blue cardboard cover protects the entire packaging, revealing only the capsules, which are inside a dense, black foam mould. Removing the protective layer reveals the brand's classic black zipped case. It is of sufficient size and has the logo inscribed in its centre. Inside are accessories, but there is also a cardboard case with the rest. In brief, the contents are as follows:

• The two Wind capsules.
• A cable with a 4.4mm balanced connector and a 2Pin 0.78mm interface.
• A metal blister pack containing three pairs of Reference silicone tips sizes SxMxL and three pairs of Atmosphere silicone tips sizes SxMxL.
• Two foam tips.
• Three pairs of grey and yellow core silicone tips sizes SxMxL.
• One cleaning brush.
• Instruction manual.
• Warranty certificate.

One could say that this is a typical presentation of the brand, as for the Winter model it is practically the same. That said, this is by no means a negative comment. I'm very much in favour of the variety of tips the brand presents, as well as the zippered case and the good cable. Pure quality.



Construction and Design

If there is one thing that characterises the brand, it is a very careful design and superior build quality. BQEYZ always tries to recreate a special capsule. In this case it has created an almost triangular-shaped design, with rounded corners and the 2Pin 0.78mm connection interface at one vertex. The size is narrower than previous models. The outer face has irregular veins running through it, revealing a metal grid inside the capsule. Between these veins is inscribed the model name on the right capsule and the brand name on the left capsule. Purists would see a flaw because the letters are incomplete. They have been inscribed on the surface between the machined veins and this space is not always sufficient for the lettering to be printed in full. Perhaps another pattern could have been adopted with the inscription in mind. However, in my opinion, this is a minor detail. The inner side is rounded and contains the driver BC, facing away from the cable connection interface. It is an inscribed circle inside which there are two silver Torx screws and two slightly curved openings. It seems to be mounted behind the bone conductor driver. On the way to the 2Pin connector there is a white mole with the lettering indicating the channel. The mouthpiece is metallic and silver in colour. It has a small base of the same diameter as the body of the capsule, then tapers to a diameter of 5mm. Finally, the outermost part has an outer diameter of 5.7mm. The approximate length is 4.2mm. The mouthpiece is protected by a dense metal grid. At the bottom of the mouthpiece, there is a hole in the body of the capsule.
The cable consists of two coiled strands. One conductor group is silver, while the other is slightly darker. The cable consists of silver-plated monocrystalline copper wire with a diameter of 2.4mm. The number of cores is 0.05mm * 14 Pieces * 7 Parts * 2 Cores * 2 Branches, for a total of 392 wires. The 4.4mm BAL connector is gold-plated, its housing is a smooth, silver-plated cylinder with the marking inscribed lengthwise. The cable is protected by a small plastic sleeve. The splitter piece is of the same style, with the marking inscribed in the same way, but about half as long as the wire. The pin is a matching narrow ring. It should be noted that this adjustment ring is too loose and slips more easily than is desirable for its function. The cable has a semi-stiff plastic coating to give it a shape over the ear. The sleeve of the 2Pin 0.78mm connectors are silver-plated cylinders, matching the rest of the sleeves. They have an inscribed ring at the top, as well as the channel lettering in the centre. The 2Pin connectors are gold plated and are mounted on a translucent plastic base with a notch to indicate the outside of the connection and its polarity.
There is no doubt that the cable reminds me of the one used by Letshuoer in its S12 Pro model, although this BQEYZ is more flexible and less rigid, which increases its value. Lastly, regarding the cable, it comes with a cover to protect the jack and a Velcro strap to hold it in place.
As for the capsules, once again BQEYZ has brought us a beautiful, attractive, more compact and delicious design. The capsules are smaller, with a very pleasant feel and the integration of the BC driver is as curious as it is imaginative, highly interesting. Only the lettering can tarnish the perfection of the capsule construction.



Adjustment and Ergonomics

As I said, the capsules are narrower than the Winter model and do not have an anchor protrusion. In its position is the BC driver and that part is rounded. This eliminates any friction with any part of the ear. However, the anchorage is less and the sensation of rotation appears until it is fully seated in the pinna. Thanks to a good choice of tips, such rotation will not be problematic and the fit will be good. In my case, using my classic large foam-filled tips, the fit is remarkable, the movement, although limited, can happen if you rotate the tips with your fingers. Still, the fit is durable enough for normal use, even for moderate activity. Although this may depend on the tips used and the morphology of each individual.
In the end, the more rounded and free interior, coupled with the smooth surface texture, may mean extra comfort for some. And so it is in my case. The fact that it is also a narrower capsule is visually more integrated into the ears. The sum of all this should make for excellent ergonomics, no doubt about it. But, in my case, that minimal degree of freedom in rotation subtly detracts from a more durable and firmer fit.



Sound

Profile

There is a mixture of a V profile, tending towards W, but always with an inclination towards the second half of the graph, something that could be concluded as a neutral-bright profile. It can be seen that the greatest emphasis is placed on the mid-highs, although there is good control in the treble, which limits any escapist feeling towards brightness, despite the good extension of the high range. I don't find the Wind to be warm, nor do I find it to possess a bass-oriented character. Thus, the result remains a more neutral centre that is well represented at both ends.



Bass

I didn't want to measure the BQEYZ Wind until a few days after receiving them and my surprise was that I had more bass impact than I thought. And, sure enough, in a way, the bass performance improves on the graph, thanks to that mute component called the BC driver. The Wind's bass is slightly coloured, although there is a duality in its behaviour thanks to the mix of both drivers. While it seems that the DD driver is the culprit for the slight colouring, the BC driver adds a dual character that shows a deep, sensory side that can be felt from the lowest LFOs. The behaviour produced by the blend gains in nuance, descriptiveness, texture, even punch and physical feel. And this combined sensation is very pleasant, engaging, even addictive, and is the reason why the bass works so well in the mix, providing a very unique sonority in this segment. The great interplay between the two drivers is the reason why the bass has such a complete behaviour from the lower end of the audible range. On the one hand, there is the physical and sensory capability of the BC driver, which also adds depth, accentuating texture and competence in the descriptive aspects of definition and resolution. On the other, the dynamic driver adds the punch, physical volume and air movement that bass requires. The gentle mid-bass orientation gives it that rounder, slightly colourful edge, which is balanced by the sensory aspect of the BC. In this way the Winds have the best of both worlds without the lower range being predominant. Surprisingly, the marriage of the two never penalises speed in execution, nor does it penalise recovery. On the technical side, the Wind is very good. The hit is fast, compact, very tight, with that slight colour, but with no dampening, yet elastic to maintain a real and unforced behaviour.
I have subjected the Wind to my classic double test of very low frequency pure tones and this is where that dual sensory, physical and texturally maximised sensation is demonstrated. On the one hand, the low end is barely audible, but you feel that deep, physical vibration from the BC. As the frequencies increase, the sound mixes with the vibration and the dual sensation emerges that is both appreciable and powerful. The second classic test is the reproduction of very dirty, powerful and unfiltered bass, where the bass drivers are put against the strings in the worst conditions. The result is even better than I expected. The Winds don't suffer at any point, they even have the ability to sweeten and smooth the passages, without showing a hint of suffering, congestion, smearing or fuzziness. On the contrary, in these bad conditions, the bass responds with such smoothness, speed, definition capacity, generating very agile transitions, fast and completely adapted to reality. It's able to combine the bass punch with the bass lines without mixing them, delimiting both in a very defined way, with a great resolution, vivacity and capacity to generate layers and stratifying the bass in a totally enviable way. Possibly one of the best performances of these complex passages I have ever heard. It just lacks a little more power, darkness, volume and weight to be the perfect bass for a bass lover like me. But for a model whose focus is not on the lower range, the performance is outstanding.



Mids

Another great aspect of the Wind's bass is its low midrange intrusion, although it is true that the first part of the midrange has a good presence contrast compared to the second part, something that can be seen in the frequency response. But, equally, the BC driver seems to rescue the situation once again. Its presence prevents the mids from being as polarised as they might appear. On the other hand, its contribution helps the sound to be very splashy, articulate, vivid, dynamic and fast in its transitions, offering a sense of speed and sparkle that adds a very particular effect of movement that is difficult to find in this price segment.
Even so, the male voices are not free of a certain remoteness, appearing somewhat lean and lacking in physicality and body. Very little would have been enough to make them appear opulent, lush and warmer. Unfortunately, this has not been the case, and this benefit has been relegated to the female voices. It is in them that the full power of the Wind is demonstrated. But going back to the first half of the middle range, they are undoubtedly mid-distance, with a great definition, as well as a good timbre, because it is not brilliant. Although sibilance can escape even in the male voices, if they show any hint of such a drawback. Likewise, the instrumentation of this initial phase is light, without much force or physical sensation, something that detracts from the forcefulness, energy and punch of the sound of this part. This is how a certain immersive capacity, volume and power towards the listener is lost. On the other hand, this is compensated for by the sense of movement and dynamism that I have already mentioned. It is not the body or the energy that surrounds the listener, but rather it is that sense of very articulate, vivid, sparkling, constantly moving sound that makes the music dynamic, rich and splashy. The Wind will never present the music as a wall of sound, but will make it sound like fireworks, with a very high dynamic range and expressiveness. Thus, despite the thinness and middle distance of the first half, this phase is very rich and descriptive, without the timbre being compromised by the clear contrast between low-mid and high-mid. The second phase is another matter, in which the necessary physical strength and presence appear, without losing any technical aptitude. The female vocals sound fuller and meatier, the guitars sharper and more energetic, as do the strings and other instrumentation with their base in this second part.
In terms of expressiveness and definition, the exaltation of the mid-highs elevates the timbre of this part and the sparkling capacity of the sound becomes more analytical and expressive, bringing details and nuances closer to the listener, sharpening them and filling them with energy. It is even possible that this explosion of resolution behaves negatively for the micro-details in the background. Even if the Wind has sufficient capacity to express both, the prominence of one over the other can work against it. This is where this model's enormous sense of openness comes to the rescue. The Wind has a very separate and open sound, where the stage is very wide and volatile. There is room for all these details, despite the difference in energy and planes between them. It is also true that this predominant presence of the upper midrange can compress the layering of the music, but there is still room for them, as long as they do not overlap frequently, as they will then be diluted by the exposure of those closer to them.



Treble

Coming from an excited upper-midrange, it might seem that the treble would be the pinnacle of energy. But, thankfully, this is not the case. The high end tuning is more classical, alternating peaks and valleys to offer control and diminishing extension. There is a nice initial sparkle, tempered by a gentle drop that builds again to add needed harmonics to the mix. The energy level is appropriate, even pleasing after a bold display of vigour such as that at the end of the central range. The positive value is their execution. The Winds have enough resolution and definition to sharpen and thin out the high notes, adding their edge and a controlled crispness that doesn't lose the softness, but is sparkling and with enough punch to be moderately prominent and present. All in all, the timbre doesn't suffer and the treble comes across as realistic and supported, even with a good dose of air and backed by the breadth of the sound, which allows it to become more volatile, gauzy, even subtly penetrating, but without losing that realism that moves between restraint and exposure.



Soundstage, Separation

In this section it is worth commenting on the technical competence of the BQEYZ Wind. While in the low end the cohesion of the two drivers is highly synergistic, helping to present depth, texture, body, energy, punch, stratification, the ability to recreate layers, great definition and resolution; in the upper midrange this capacity is lost a little in favour of a more presential exposure of details and mid-highs, limiting the depth. All in all, the Winds offer a very open soundstage, perhaps because of the grilles on the outer face of the capsules, and also very separated, with great headroom and dynamic feel. As I have already mentioned, the sense of movement and articulation of the notes offer a very vivid and sparkling sound, totally expressive, loquacious and evident. All this generates an immersive sensation, with details that have the capacity to volatilise, but which start very close. Up to a certain point, especially in the lower frequencies, the generation of layers and the sense of stratification is very good. As frequencies rise, they come closer to the listener with greater energy, eclipsing the more distant layered details. However, those are there; when the music offers some respite, they reappear. To be sure, the Wind has the resolving power to show such micro details in quieter settings, but it does not divide well in this energetic zone, despite the outstanding separation it possesses.
Returning to the scene, the sense of laterality and height is impressive. The vividness of detail and the stereo feel is reinforced by the speed and dynamism of the transitions. The music moves swiftly from one ear to the other, like a lightning bolt, and this also adds to the sense of movement and expansiveness of the scene. There is a good degree of depth initially, but it becomes more limited as the frequencies grow. As I say, the separation is evident, but the brightness of the mid-highs and early treble blurs the notes in a gaseous way, helping to fill in gaps that could be darker or quieter. Admittedly, this effect gives the scene an out-of-head, three-dimensional, escapist feel that is valuable, if also subtly unreal.
With such a large stage and appreciable level of resolution, the image is accurate, limited only by that same gaseous, volatile effect, which can blur some elements.



Comparisons

KiiBOOM Evoke

If I want to know the true range of the BQEYZ Wind, the best thing to do is to compare them with the best, or at least with the ones I like the most. And that's why I'm going to pit them against the KiiBOOM Evoke. They may not be people's favourites, but they are among my favourites, both in terms of profile and sound.
The Evoke has a semi-custom capsule made of resin, with an external pattern that can be chosen according to price. It comes with a nice silver-plated cable but cannot be chosen with a 3.5mm SE plug. It also comes with a really big case and a single set of tips. Nothing to do with the classic BQEYZ packaging which surpasses it in all aspects. But it is also true that the regular version of the Evoke is only $169 compared to the Wind's $240. The BQEYZ capsules are made of lightweight aluminium alloy and are smaller than the Evoke capsules. Still, I prefer the more durable fit of the KiiBOOMs.
The Evoke features a classic 1DD (10mm) + 1BA for midrange + 1BA for treble. The Wind has a 10mm full-range dynamic driver, along with a 10mm BC driver for bass and midrange.
In terms of sensitivity, the Evoke is much easier to move than the Wind, which needs more power to sound at the same volume level.
Starting with the low end, it is very curious how the BC driver is able to compensate for the sub-bass deficiency of the Wind compared to the Evoke. I don't want to pretend that the Wind has the same response and punch as the Evoke, but they are closer than what is shown in the graph. It's true that the Evoke has a darker, deeper, fuller bass with more presence and energy. But the Wind's are not short on punch, although their timbre has a bit more colour and there is a hint of that duality in the bass drums. However, they have a more marked texture, they are more compact and faster, with a quicker recovery and less punch. This makes them more technical, with better resolution and definition. Both are very good at delivering complex, rich, unfiltered and powerful bass. Neither loses control, the definition and representation is excellent and the response is very pleasing. I think that the combination of both bass responses could result in one of the best basses in this range, because what one lacks, the other has, and vice versa.
In the middle zone the difference is the thickness of the notes, finer, more delicate, volatile, vaporous in the Wind. The Evoke has more marked notes, also more frontal and attached to a wide scene, but with a more classical and defined structure. This thickness allows the male voices to have more body and physicality, as well as presenting a more forceful and more conjunctive sound. Those male voices in the Wind feel more distant and with a lighter, smoother execution. Everything is broader, more detached and dispersed on the Wind, there is a larger volume that surrounds the head and tends to escape. Even the female vocals also feel closer on the Evoke, despite the Wind's brightness and clarity. But the sound of the KiiBOOMs is more concrete and somewhat drier. The Wind's thin, dispersed sheen gives it that vapour that blurs the notes as they fade away. In this way, the representation of voices and instruments is less consistent, more gaseous, more transparent. It's something at odds with the concrete, analytical point of the Evoke. The detail is fine and evocative in the Wind, it is shown with subtlety and delicacy. The Evoke is more explicit and finite, with a more obvious and marked physicality. The Wind is fickle, with a more articulate sound that manages to flow in a way that manages to be more harmonious even, not as corseted as the Evoke, more tightly bound to a firmer execution. Yes, I think the difference in the mids and highs is in the expansive, slightly distant, gaseous fluidity of the Wind as opposed to the more concrete, close, physical and tight sound of the Evoke. By contrast, the KiiBOOMs are more controlled with their sibilance, while their treble is more homogeneous, thicker, but well controlled and well matched. The Wind's treble presentation and execution is different, with a little more initial energy, but thinner, finer, but more incisive. The treble doesn't feel as full, perhaps a little more devoid of harmonics, but sharper, brighter and a little crunchier, despite that scattered feeling that is not avoided in the high end.
The scene is more frontal in the Evoke, it is wider but more defined. The distances between elements is more fixed. The Wind's scene is fluid and somewhat more diffuse, but it is holographic, expansive and three-dimensional, something the Evoke will never be able to offer. The very fluidity of the sound also gives it superior speed in transitions, being more dynamic, expressive and descriptive, as if it could represent more notes in the same time interval. This gives the Wind a technical superiority, a higher level of resolution and definition, executed in a different, more liquid, transparent and ethereal environment. The image is more concrete and physical in the Evoke, with a more discernible provenance, while in the Wind its recreation is more imaginative, freer and unpatterned. And these characteristics are further virtues of the Wind that differentiate the two great models.



Conclusion

BQEYZ believes in its options and persists in its line of improving its drivers and alternative hybrid designs. This great work is reflected in this new Wind model, 1DD + 1BC completely open, dynamic and surprising. The Wind offers a whole sound experience that will leave no one indifferent. Starting with a low end that is more than it seems, the Wind presents the sound in a very articulate, expressive, vivid, expansive way, offering a mixture of fluid sound, between liquid and gaseous, of great resolution, detail and definition, with a holographic and three-dimensional scene, as well as a great performance in all the bands. Without discussion, one of the best models of the brand and way up there among the competition in its price range that I have been able to test.

INTRO

BQEYZ is an audio company from China that have about 10 years of audio engineering experience. They've release mostly hybrid IEM from ultra budget one like KB100 to tribrid like Spring2 and lately they've begin to explore bone conduction hybrid with the Winter.
Today I will review the BQEYZ Wind which is their second attempt at bone conduction hybrid.
The WInd use a 10mm LCP dynamic driver and a 10mm coil bone conduction driver that was self developed by them.
Unlike alot of unserious chifi companies, BQEYZ patent their own driver and invest alot of time into research and devlopment, this explain why they release 1 or 2 IEMs a year unlike those mass production chifi maker.
BQEYZ are a visionarry company that don't follow any tread and pursue their own audio engineering quest, don't expect harman tuning from them, nor to look above the shoulders or audio gurus or other competitor, they follow their own path, and this is one of the reason why I respect them.

The Wind is first IEM release of 4 IEM model inspire by weather element.

Let's see in this review if the Wind worth our consideration or will just be one more chifi IEM passing like a breeze.

CONSTRUCTION&ACCESSORIES



The craftmanship of the Wind is exemplary, its all made of CNC machined metal and have great caring about details. It's a complex yet sturdy housing construction. It's true semi open back with a grill.
Front part of housing have the bone conduction driver that need to be in contact with your skin, the shape is small and ergonomic enough to permit a secure fit. While not the best in termof isolation, the unique bone conduction transmission tend to make you less aware of outside noise.

The 2pin connector is only part I feel BQEYZ can improve, their a slight gap around connector that might loosen with time or collect dust.



The included cable is a 4 strand braided silver plated litz copper cable of excellent quality. The strands are thick and smooth, soft and flexible and promise good comfort and don't create any microphonic. As well, you can choose it in 3 plug type: single ended 3.5 or 2.5 and 4.4 balanced.



The packaging is elegant and minimal but accessories are generous. We have this excellent cable. 10 pairs of eartips including one pair of memory foam tips. The carrying case is basic in term of quality and a bit too small for my taste. All in all, construction and accessories are very good.

SOUND IMPRESSIONS



Firstly, their no other IEM that sound like the Wind and if you aren't familiar wiht bone conduction, this could be either underwhelming or overwhelming depending of your psychoacoustic awareness. For me, it's an utterly fascinating and engaging listening experience that feel effortless in holographic musicality that fully immerse me in whole mid range like not other IEMs ever did.

Unlike the BQEYZ Winter that cover treble section with its BC or UM Mext that cover wide range up to 7khz and add alot of presence definition and texture, the Wind BC cover sub bass to upper mids smoothly, organicly, and add lower mids delicacy as well as infra bass density to an overall darkish tonality.

This is a very atypical take and the graph shared by BQEYZ don't translate at all what you will perceive in term of tonal balance, in fact, I don't even think they add the bone conduction vibrations measurement to it.

So we can say warm to dark neutral sound with slight bass, lower and upper mids boost then a flat treble that begin to roll off after 10khz, so don't expect ultra crisp, analytical or snappy highs with the WInd, it's smooth and macro dynamic is organic as a whole, the 2 drivers mixing togheter like a impressionist painting mix it's colors.

The BASS is so unique and offer such a flexibility of attack and effortless layering that it will be main hate or love affaire for consumers here, in the sens the presence isn't very textured yet the tone pop up magically, the ''oomph'' is round and vibrant even in ultra busy track, the sub bass dig very deep and can deliver new dynamic tactility like speed shifting in bass line or when bass line sliding change tone you suddenly are super aware of it.
It feel like your head and mind become your body in a room with proper sub woofer, it's very hard to describe because frequency lower than 200hz aren't bright or full of micro details, this come from treble section which is tamed here. So, while the bass isn't edgy and super thight in presence definition, it's the fundemantal lower harmony that can be perceive, which is about dense round tone release that often get lot in the mix under noisy texture.
Her it's all juicy, bodied and multi layered in a mellow dynamic.
Yes, mellow. These Wind aren't basshead and just slightly bassy, I mean, when the bass is super boosted in a track it will deliver the dynamism, but never in a loud or fatiguing way, you'll feel the hit or boom in middle of spatiality, 3D way, you can barely touch it if you want since it's so tactile and densify with extra weight.
I can feel the dynamic driver mid bass punch mixing with extra bone conduction vibrant density, it improve the layering with bass line, both having their diversify dynamic presentation cohabiting togheter. Kick drum is round and lush, texturing is subtle but natural, it's presence is embossed with lower mids warmth and the lead attack have this well felt assise. It's an excellent fully bodied reproduction of this instrument.
And the cello is another bliss to enjoy, the level of richness here is magnify in both tone, timbre and presence. All the subtilities of this instrument are reproduce in it's whole range without any lower harmonic by passing as it often happen with non bone conduction IEMs. The melodic line are wide and envelopping the listener, entering it's head and opening out of it, vibrancy of air is perceivable, you can't mix cello with violin with the Wind, the soul of cello is fully extract with a clean lush presence and bodied but not overly warmed tone, the bow hit are extracted without harshness of sudden volume boost too.
Hard to restitute lower range percussions like toms and some congas are superbly restitue too, fully opening in natural resonance without the acoustic distortion issue inherent to air resonance, so the rythm line is very articulated in macro and micro dynamic.
The for double bass, it gain extra density in it's extension as if air release get creamier a bit which improve layering but affect a bit natural transparency that should be thinner i feel.

If I praise that much the bass, be ready for even more wow effect with the mid range, which make me conclude the Wind is rather mid centric, at least, bone conduction wise.
In fact, as strange as it can seem, the Wind is near analytical for whole mid range, then become darker from lower treble and up.
It's extremely rare than IEMs extract sound info in lower mid range and it's what we get here, this is very exotic and more you listen to it more you are blown away by level of sound info it extract, sometime it can even be too much for recording thaty over abuse voice doubling since you can perceive it all. Yes, you suddenly have absolute hearing for the mid range, effortless way.This mean whatever number of instruments playing in similar mid range, it will not mix togheter and darken each other, it will flow organically in highly readable sound layering.
When I play Goldberg Variation conterpoint interpretation by String Quartet, i can't believe how easy it was to follow each individual phrasing that interlock melodic line. This was near too much for my mind since those composition can be interpret in multiple way by the listener, here I have full freedom to lisen to each instrument phrasing precisely, with a natural full tone, not a thin brighten one, it was both highly technical and musical, unforced way. You aren't forced to perceive this that clearly, yet, it's there, calmly.
Because at they end, the mids pop in and out of your head in a rather lean and innoffesive way, the upper mids aren't boosted in loudness so when you go listen an harman tuned IEM after the WInd, female feel super shouty and fatiguing.
And those female vocal are wonderfull for sure and always well layered and upfronted softly. The presence embrace you and inteligibility of each word is clean in articulation, this is another aspect that make you perceive harmonic distortion and euphony more with non bone conduction IEM too. So, if you find important to follow lyric of your singer precisely, the Wind is a great answer. From Snoh Aaleegra, to Elina Duri to Arianna Savall to Baby Rose, I always have an intimate and exclusive momentum with the sweet vocals. Even with track that go easily muddy like Fight Club from Baby Rose, the vocal didnt get veiled by dominating bass line nor the presence was too thin or raspy, it was sticked above rest of macro dynamic with a clean precise bass line that don't throw air resonance above the mids.
Same goes for male vocal, which are fully bodied, don't get muddy and have clean fowards presence with excellent transparency.
Their alot of instrument and even percussion that are within 600hz to 4khz section, and this is where the WInd will make your heard things you've never heard. Not only back vocal doubling but new sound layers too like synth pads layers that will fully blossom and float in vast soundscape, or some tabla percussions in lower mid range you don't even know exist, or snare drum fine details, or this obscure woodwind instrument in brass ensemble that wasn't as loud than other, all what is hidden in mid range is gently reveal and it has been problematic for one or 2 songs that I can perceive layers compression unfolding, like same vocal track that should mix with main one but is too easily perceivable.
To comple this wordy mid range covering, i'll end with my favorite instrument: the acoustic piano. The Wind will amaze piano lover with how smooth yet richly and full detailed the presentation is. It's never recessed, we have felt note weight, the presence is fullfill with all harmonic in a natural unforced way and when pianist play damping or sustain pedal, you can perceive the note stop or extra release very easily.
Their no doub that the Wind offer one of most mesmerizing mid range of all sub-300$ IEMs i've test. Holographic, intimate, multi layered and so natural yet never lacking subtilities in timbre. Just sublime.

When it come to treble, the word ''Sfumato'' come to my mind. It's full of contrast, yet a hint hazy and dark. While we don't feel a bone conduction imbalance like the Winter, it tend to cream bass and mids with extra info that blur a bit upperr treble starting around 6khz and then when it go pass 10khz, their a roll off happening that stole air, sparkle and brilliance.
These aren't for treble head even if curious ears addicted to micro details will be please with rich rendering of the Wind.
I'm not certain up to which treble section the bone conduction driver cover, but I have instance of intense micro details that were sharp and cymbals clang are crisper than the sizzle for example.
So the percussions aren't all treat on same resolution level which make some get lost in the mix more easily since above 6khz it seem attack edge goes blurred-softed and it's harder to appreciate fast snappy cymbals, while the snare is notably cleaner and snappier that upper range percussions.
The guitar is hit or miss too, it's full bodied and rich in low and mid harmonic, but when it play higher octave that need cleaner decay and sparklier release it feel foggy a bit.
I would say the Wind is a specialist of violin, saxophone, soprano female vocal and even the very hard to restiture harpsichord which sound full and not thin and distant but lack just a bit of extra air release.
But it isn't for classical guitar nor harp and full range of percussions due to the fact the DD lack extension and the BC put a sheet of sound info that damp attack release including sparkle.
Safe and refined treble for long listening pleasure, not for those that love their highs very boosted, spiky, super snappy or sparkly.

The Soundstage is near impossible to describe, so the over abused word Holographic come to help yet imagine a multi layered spatiality where your in middle of the stage but you are the stage too since music come and go in and out of your head. You have a very wide first macro image that surround you in a U shaped way then center stage is your head, these 2 spatial plans do mix togheter and dont feel 2D but 3D. So its a very circular presentation with an intense immersivity appeal.

The imaging would be better with more treble for sharper definition of separation in stereo direction, but while macro resolution feel thick and slightly homogeneous as a whole, the sound layering is excellent and permit easy separation of mid and low range instrument. Not in a monitor like manneer but about those dense soundwave projection that dont go muddy even if rather warmed in presence. It's not a realistic positioning, its about seing the sound layers flow around you, their color dominating the texture edge.



SIDE NOTES

It's unclear what the sensitive specs are and for impedance, it's stated as 33ohm to 100ohm. Anyway, even before seeking for the specs it was evident the Wind need proper amping. I would suggest a minimum of 100mW@32ohm. The Wind do scale up with source and will not distort with high impedance load, I get incredible result with Hifiman EF600 (5.2W@32ohm)

In term of eartips, the one included are OK and i tend to use wide bore eartips so even with shallow fit the bone conduction drivers is in contact with my skin.

This is important to get the housing in contact with temporal bone, closer it will be, more evenly boosted will be bass and mid range.


COMPARISONS



VS BQEYZ WINTER (1DD+BC-240$)

The winter are brighter and a hint more W shape in their balance so we have edgier mid bass, upper mids and upper treble. Wind feel more warm neutral, more organic in balance and darker on top, less crisp and airy than more analytical WInter.

The bass is more rolled off in sub bass with the Winter, the bass line are not as well layered and articulation isn't as agile and feel sometime compressed in dynamic, strugling more with natural bass extension. Texture presence of those bass line is more boosted with winter yet infra bass ''oomph'' can't be extract in busy music properly unlike Wind that use bone conduction to freely extract sub tone. Strangely, Wind isn't as hard hitting, but do offer better kick drum layering, effortless mellow way.

Mids are brighter and more shouty with Winter, it make us feel female vocal are more upfront but they are just louder through air while fuller, smoother, wider in presence and cleaner with the Wind. Timbre is more natural and less rough with the Wind, the mid range layering is better and can extract more subtilities like multi vocal used for the mix are effortlessly magnify with the Wind, violin quartet of similar range playing toghter too are better layered. Definition is less edgy, lower mids is more boosted in your head and add liquid warmth to sound enveloppe while it's the opposite with WInter, the BC boost presence but make timbre thinner, dryer, brighter. WInd is notably more mid centric than Winter.

Then the treble is more lively and extended with Winter, it extract more micro details and offer edgier-snappier attack. It add a bit of metallic sheen to percussions which sound a bit more artificial than darker rounder one of the WInd. Highs are more airy and open with the Winter, the Wind keep them in the back.

Soundstage is wider and taller with the Wind but notably deeper with the Winter.

Imaging is sharper with Winter, you struggle way less to position percussions properly yet bass line in busy music will be easier to pin point with the WInd, as well as mid range instrument. Nonetheless, WInd is more laid back and not as good for accurate monitoring purpose.

All in all, the Winter might be more treble centric and technical sounding but ultimately it never trigger any emotional response in me, unlike the more mid centric Wind, which is smoother and less fatiguing for long immersive listen, and offer superior bass performance too.

VS UNIQUE MELODY MEXT (1DD-4BA-1 wide range bone conduction-1000$)

OK, this is quite interesting and mind puzzling unfair comparison here, yet not bass wise since the Wind seem superior in that regard, less prompt to unwanted resonance and better rounded, cleaner in punch, in a smoother less boomy way.

But technical superiority stop there, yet timbre and tone wise the Wind is more natural to my ears, more cohesive and less prompt to artificial mix of texture details which is notably more boosted with the sharper sounding Mext.

Suddenly, the WInd feel L shape in balance, with leaner but thicker mids and darker treble, the Mext is notably crisper as well as more lively sounding, less laidback.

The bass is achille's heel of Mext and the DD resonance blur more the roundness of kick impact, which is more tactile and well layered with the Wind even if not as boosted in texture. Mid bass has proper note weight and sub is less boomy.

Mids are more open and clean with the Mext, they are brighter too and less polished in upper mids, vocal are leaner and more creamy, fully in lower mids with the Wind, but imaging isn't as edgy and well define in separation. Ultimately, the breathy or contralto and baritone vocal sound lusher and smoother with the Wind. Woodwind instrument too has more natural tone, less pushed presence, wider yet not as boosted in trasnparency presence.

The treble is notably more vivid, airy and detailed with the Mext, attack is more snappy and edgy, faster and more controlled. Highs are more textured and have more definition bite. Attack edge is more blurred with the Wind and mid range will stole the show and left behind percussions more. Wind is more permissive of bad recording and will not extract unwanted noise artefact unlike the more analytical Mext.

The soundstage is slightly wider with Wind, but taller and deeper with the Mext.

Imaging is notably better with the Mext, positioning is next level precise and overal darker imaging of Wind can't offer as holographic and sharp instrument separation in both X and Y axis.

Well, it was predictable that a 4x pricier IEM would at least offer superior technical performance but once the wow effect has pass, i feel tone and timbre of Wind is more natural and I tend to enjoy it's warmer tonality longer. The Mext extract so much details and texture noise that it can kill the musicality for me, it's the opposite with the Wind that don't force me into high resolution listening.

CONCLUSION




After having listen to about 500 IEMs in my audiophile journey, it's rare I get surprise with a novel type of musicality that I've never heard before. I can say it happen once or so a year and after the UM Mest MK3, it's only IEM that achieve exactly that: delivering me an immersive effortless mid centric holographic musicality like no other.

BQEYZ stand apart in chifi audio realm, and open new acoustic doors with their devlopment of bone conduction driver that are implemented differently. The fact sub bass and whole mid range is magnify by the mix of DD dynamic and BC resolution is a fascinating approach to a new type of musicality.

If like me you feel too often that mid range instrument are half cook, too thin or too blurry or too bright and boosted in presence, the Wind will be a revelation since it's both full tone and smooth presence that are put fowards in an effortless macro rendering.

Im extremely impress by the refreshing musicality of the Wind and highly suggest it to those that can't take more of harman target tuning or too V or too U or too trebly tuning and seek for a lush mid centric tonality that is both exotic and cozzy to listen too.

Very highly recommended!!



-----------------------------------

PS: I want to thanks BQEYZ for sending me this review sample. Ive no self benefit involved with this company and as always I don't participate to any affiliated program and these are my 100% honest subjective audio impressions.


You can order the Wind for 240$ here: https://www.aliexpress.com/item/1005006042191996.html

In climatology definition, Wind is a natural phenomena where movement of air across the Earth's surface plays a significant factor in controlling and determining the weather and even climate in a certain region. The reason for the occurrences of different scale wind movement or atmospheric pressure are due to the variable thermal heat on both vertical (poles) and horizontal (equator) parts of earth's surface and also an inertial movement and rotation of earth also known as Coriolis effect. Gusts, squalls, breezes, storms, hurricanes, monsoons and typhoons are connected with the strength and speed of the wind.


After the end of BQEYZ's Season Series as we all know that this was the line-up section for their flagships, They decided to introduce their latest flagship line-up range, The Weather Series. This unit that I have here right now is the first model of its class, The BQEYZ WIND.



The BQEYZ WIND like most of its Season Series predecessors (with the exception of The Autumn) is also a hybrid driver set-up and we also know that BQEYZ are one of the few audio companies that striving to be innovative as possible with their R&D department constantly experimenting and improving some existing audio technology and a new generation of bone conduction driver was their technological achievement from their almost a year long effort on developing this one alone.



BQEYZ WIND has a hybrid driver configuration consisting of a newly-developed 10mm voice coil-type copper bone conduction driver and a dynamic driver of similar size with LCP (Liquid Crystal Polymer) composite diaphragm as its supporting driver to handle other parts of the frequency range. The voice coil-type copper bone conduction driver is quite different from the other bone conduction driver that was implemented on both Winter and Winter Ultra as the previous one is based on a piezoelectric mechanism that is almost similar with typical air conduction process which handles midrange to ultra high frequencies. On the other hand, the newly-developed copper bone conduction which has a vibrating reed made of steel and it was suspended in part of its cavity base shell that truly transmit a low and midrange frequency waves directly to the ear cartilage (yeah, cartilages are soft bone connective tissues after all) then transmit those vibration through the skull and somehow skin to give that immersive and ambient feel. So in principle, this type of bone conduction driver really works like a bone conduction system from other hearing aids with better transmission and material that really benefit the quality of its sound. The supporting LCP dynamic driver has a dense, quite responsive vibration for better clarity, detail retrieval and brighter treble that this driver solely handles some parts of midrange up to the ultra-high frequency.



The dual hybrid drivers were enclosed in a CNC-milled aluminium alloy shell chassis and then it underwent a sandblasting and anodising process to give an even texture and smooth surface. On its faceplate, there are some laser-cut hollow slits that remind me of a Chinese script (it means "Wind" according to BQEYZ's ad). The cavity base part area of the shell is where the bone conduction driver is situated to contact the anti-helix or concha part of our ear with vibrations and also there are vent holes for an outlet of excess air pressure generated from high performance drivers. BQEYZ offers two colour options to choose from, an ultramarine blue and silver grey. Overall, the shell design of the WIND is somewhat a semi-open back one, but surprisingly it has a good sound isolation for that particular type of shell design. Like all BQEYZ sets, it has a 0.78mm 2-pin connector as its interlocking mechanism which is known to be a more stable and proven detachable mechanism.



All BQEYZ flagships were known to have a high quality stock cable and BQEYZ WIND is no exception in that regard. The stock cable of this set is actually a new one as it has bi-colour combination of white and grey. It has 2-core, mono crystalline silver-plated copper wirings that were insulated with PVC coating. It has metal alloy on its termination plug and upon ordering this set, you can choose three types of plugs; 3.5mm SE, 2.5mm Balanced and 4.4mm Balanced. Altogether, the stock cable is soft, well-balanced on its texture and yet durable for long term usage.



Also, another cable from BQEYZ that I will insert here and it's a variant of their LIME/RIME cable. This RIME cable has 4-core strands of crystalline silver-plated copper filled with an insulation layer which makes it supple, more flexible and quite durable too. It also noted that the RIME cable is a modular one where you can interchange its termination plug based on the availability of the output jack(s) that your device has. There are three included termination plugs to choose from and they are gold-plated to ensure better conductivity, these are 3.5mm SE, 2.5mm balanced and 4.4mm balanced.



As for fitting and comfort, BQEYZ WIND shells appear to be lightweight for its all-metal alloy construction that I can wear it into my lugholes for a long listening session. Once again, I will mention regarding its semi-open back design, The WIND was able to block some external noises from the outside environs as I usually do some brisk walking daily.



For its product packaging; BQEYZ is one of the audio companies that present their product presentation in a very organised and appealing as it includes many accessories in particular to be utilised.



Here are the contents inside of BQEYZ WIND:

■ Pair of BQEYZ WIND IEMs.
■ Stock cable.
■ a zippered PU-leathered IEM case.
■ Three (3) pairs of vocal/reference ear tips in different standard sizes.
■ Three (3) pairs of balanced ear tips in different standard sizes.
■ Three (3) pairs of bass/atmospheric ear tips in different standard sizes.
■ Pair of memory foam eartips
■ Ear tips plate.
■ Cleaning tool.
■ Paperworks like instruction manual, Q.C. stub and warranty card.



On required power efficiency, BQEYZ WIND can be driven decently with sufficient power output from multimedia devices like smartphones, laptop and tablet. But should be noted that this set will definitely scale well on sources with medium and high gain mode output as it will truly show its full potential to have a full and vivid sound quality.



As for tonal profile, It is quite a norm that almost all BQEYZ flaghip models are known to have a balanced-neutral tuning on them but this time, they take another variety of a neutral sound. BQEYZ WIND has a warmish-neutral sound signature as it has more emphasis on both low and midrange frequencies with a tad boost on the upper midrange up to presence part and the rest are neutral and linear presentation on high frequencies. Some listeners might perceive the BQEYZ WIND as an L-shaped, bass boost neutral sound.




LOWS/BASS:

With the bone conduction that handles the low frequencies, it gives a different experience on listeners on how BC (Bone Conduction) bass would sound like. The bass response of The WIND is quite tactile, punchy with consistent rumble on its sub bass presence to give that ambience-like dynamic vibe within my aural sense that few sets with BC drivers able to deliver it. I'm quite familiar on this kind of experience as I was able to to test some TOTL sets with almost similar tech namely the "Kinetic Bass" of some Fir Audio sets, the Weapon X Bone Conduction technology of Empire Ears Legend Evo and the much vaunted bone conduction driver technology on some Unique Melody sets like from MEST II & III and Mason Fu Sang.

As I mentioned a while ago about the quality of its sub bass, it has a good depth and noticeable reverberations that I perceived it clearly from sub-bass focus tracks with low tone bass guitars, octabasses, synthesisers and drum machines. Meanwhile, on mid bass, it has a well-textured note weight to give a more body and darker tone on some bass instruments and male vocals. Let me describe some tonal characteristics of each instrument that I will mention here. Bass kick drums do have a full, resonant and thudding sound that is able to sync with double bass kicks from rock and metal tracks. Bass guitars have a rather broad and sombre sound and it should pay heed to its well-detailed string notation of bassist's plucking techniques, either its basic strumming, slapping or fretless. Bass-baritones vocals should sound thick, dusky and with a dark tone, and this set is able to deliver it in almost tonally precise manner as it has a good depth and guttural sound that these vocal types should have.

MIDRANGE:

This is BQEYZ WIND's strongest part and it was its midrange presentation. It has a forward presentation with well-textured, smooth, organic, properly balanced of its warmth and quite detailed sounding. This kind of tuning will be versatile and comprehensible to all types of vocals, either male or female and most instruments will sound very natural and engaging sounding.

On male vocals, it gives a good depth, volume and definition on baritones, tenors and countertenors to sound natural and tonally accurate. Baritones of all types will sound plush, velvety and rich. Tenors that have a distinguished full and energetic sound will have those brassy and dazzling characteristics that both leggero and lyric types will have their bright and flexible vocalisations on hitting their respective ranges. I really like how the countertenors sound on this set, they have smooth, tender and light falsetto voices yet with good vocal density. Female vocals are also quite remarkable here too as it has sufficient energy and brightness to project even with vocals with highest range and register. Contraltos sound excellent on this one as they have those lush, rich and strong vocals. And then, mezzo-sopranos seem to have musky, smooth and velvety sound characteristics that I really want as they sound very mesmerising and comforting to my ears. Soprano sounds quite bright and spacious as they have a good depth and sufficiently rich tone although there are some matters that we might want more energetic and vocal flexibility on some lyric and coloratura-types of sopranists in which BQEYZ WIND might be a little bit lacking but it able to deliver a natural and detail sound.

When it comes to instruments, they all quiet sound natural, evocative and faithful to its tonal colour. On string instruments, guitars have these overtones and balanced sound on every pluck and strumming in its string notations on which ideally they should sound crisp and bright in my opinion. Violins have vibrant, lustrous and full sound on their strings on every movement of their bow stroke. On brass instruments, trombones have a brassy and solid sound, while trumpets have that stately, full and vivid sound from them. Horns and tubas have these warm, full and ponderous characteristics as they have those deep resounding sounds. Woodwinds instruments like concert flutes, piccolos, clarinets and saxophones, it has mellow and rich sound or concert flutes, a graceful and clear of piccolos, a rich and warm sound of clarinets and although saxophones have similar sound characteristics with the clarinets but in some tracks they sounds more "dramatic" and sombre. And last but not the least, the percussive instruments, snare drums have hard and clear sound in every stroke, field drums have that venerable and hard sound. And then on kettledrums, they have a deep and resonant sound and while tom drums have similar timbre with it. The pianos sound very even and balanced here with enough warm and sufficient bright tone on it while harpsichord have soft, metallic and silvery sound from them.

HIGHS/TREBLE:

The treble quality of this set is relatively balanced as it has a sufficient shimmer and smoother response. I noticed that it has a mild boost on the upper mids to give a solid attack of instruments especially on percussions and even rhythmic ones and also, vocals are more expressive and well-articulated. In the presence part of its high frequency seems quite crisp, clear and detailed sound and I don't encounter any jarring, stridency and sibilance at all even on my preferred testing tracks which are known to be sibilant-laden.

As I observed, cymbals have a rather lustrous with ample shimmer and sizzle sound. The hi-hats have a shortened buzzing sound that this set is able to reproduce faithfully. Celestas have those "heavenly" tones as they sound so ethereal, bell-like and sweet to my ears and glockenspiels seem to have that brilliant and lustrous sound. The brilliance part of The Wind has a substantial amount of harmonics as it has a good sparkle with moderate treble air extension in which I wish for more quantity on this one.

SOUNDSTAGE, IMAGING AND OTHER TECHNICALITIES:

As all BQEYZ sets that I've tested so far, they are all quite technically competent and this set is no different from its predecessors when it comes to technical performance. Sound/speaker stage of this one is quite roomy as I perceived the expanse of its sound width, a good height reach and immersive depth between front and rear. In general, it really gives my aural perception a spacious head room along with some quirks from its bone conduction driver.

On imaging presentation, BQEYZ WIND projects a three dimensional, atmospheric kind of spatiality where I can even accurately locate the positioning of instruments and vocals especially on a live band performance and full orchestra ensemble. It has an excellent separation and layering as I was able to perceive those spacing and gaps of sections of instruments and vocals with well-defined stacking of layers of each instrument and vocal tonal frequencies. With the added capabilities of a bone conduction driver, it gives that unique experience as it definitely gives that lingering, bloomy and resounding effect that envelopes within the ends of its sound field.

The implementation of two types of driver here in BQEYZ WIND is quite excellent as both drivers perform in a homogenous and cohesion manner with fast transient speed and in tandem with its bone conduction, it gives a resounding and even darker tonal pitch on some instruments.

BQEYZ WIND is also excellent on resolution capabilities especially for a set that doesn't have any BA (balanced armature) driver at all for more precise and better detail. It has remarkable macro-dynamics due to its textured note weight and well-precise musical notation attacks, then a balanced sharp detail definition as it extracts some nuances and detail infos from an audio track.


PEER COMPARISONS:

BQEYZ WINTER

● This is the WIND's predecessor model and also has a similar hybrid driver configuration but its functionality for handling specific frequency response is quite different. It has a larger dynamic driver for low frequencies and a piezoelectric based bone conduction driver for mids and high frequencies. Like its successor, WINTER's shell chassis is made of metal alloy.

● The WINTER's tuning is leaning towards being balanced-neutral sounding. It has a tighter bass response, more vivid and engaging midrange and a bit brighter treble with more air on it.

● Both have similar technical performance with the exception that WINTER has a tad sharper definition on its micro-dynamic resolution.


FIR AUDIO NEON 4 (DEMO)

● Like the WIND, NEON 4 has an all-metal build shell chassis and also a hybrid driver configuration. But the big difference between them were that NEON 4 is considered as a TOTL flagship IEM which cost over two grand (either in US dollar or in pound sterling), second one is that its shells are a bit heftier and more chunky with sapphire glass on its faceplate and the last one was that its multi-driver set-up were consists of a proprietary hybrid dynamic driver which also has a bone conduction capability and three custom balanced armatures drivers.

● As for its tonality, NEON 4 has a more mild U-shaped sound profile in my lugholes. It has more robust and haptic bass response and a similar texture on it midrange, while it has a natural tone and timbre on it, it's a tad colouration on it to make it more engaging, Treble response on this one is rather smooth, linear and only has a moderate treble air.

● On technical capabilities, NEON 4 has similar soundstage dimension with the WIND but its stereo imaging projects a more concave presentation and for a TOTL set, its separation and layering capabilities were rather average to above average given that I've tested a fairly substantial units of TOTL sets with better technical performance.


UNIQUE MELODY MEST III

● Another TOTL set with a bone conduction driver on its internals, MEST III has a more chunky shell chassis made of composite materials, majority of its materials particularly its base cavity is a solid carbon-fibre. With its large shell chassis, it has an array of four types of driver aside from its proprietary bone conduction technology, it has dynamic driver, four (4) balanced armature drivers and a quad Sonion Electret/"Electrostatic" drivers. It also has a more premium fibre-sheathed stock cable but unwieldy and less flexible compared to WIND's stock cable.

● When it comes to tonality, MEST III has a more balanced-neutral tuning that UM envisioned on its latest generation of their MEST series model. It has more balanced bass response but it has very clear sub bass rumble along with more ambient and reactive bone conduction to give that unique experience ( UM claims that its BC driver starting point response is at lower midrange area), a more transparent, detailed and a tad cleaner midrange and a tad brighter treble response with excellent sparkle and well-extended airy treble.

● On technical capabilities, MEST III easily outmatched the WIND in any category. From a cavernous sound/speaker stage proportion, superb separation and layering as it really dissects each instrument section and tonal and frequency layering and resolution capability. WIND technical performance is impressive in its price but MEST III is a different beast to deal with.


In summary of my assessment regarding this set, BQEYZ WIND is a hybrid set with a new generation of bone conduction technology that BQEYZ painstakingly developed for months. And with a different approach to its tuning and new sets of its inclusions. BQEYZ WIND tries to differentiate itself from its predecessor models.

As I end my review here, BQEYZ WIND is a testament of BQEYZ's persistent on its pursuing innovation and takes some time to be refined product and primed for portable audio market which became more competitive at constant rate. If you want a midrange performance for less, then BQEYZ WIND is definitely one of them and I will definitely recommend this one without a doubt.
