BQEYZ BQ-10

INTRODUCTION

BQYEZ BQ10 is one of the newest under $50 contenders in the recent audiophile scene. (1) But what makes it different from other options like G1, ELUA, Bunny, Aurora? Is this another IEM that came to make the market more saturated or (2) is it any budget defining IEM that needs your attention? The answer is a bit more complicated than I thought initially & let’s discuss that.

I compared a lot of budget IEMs in my recent YouTube video, here is the link –

Do give it a watch before purchasing, you knew IEM, but leaving this said, let’s discuss what is different with the BQ10.


PRICEPOINT

Although the price point of the IEM is in the budget range, but they didn’t aim for the ultra-budget where there is a lot less competition than the budget range, this shows the commitment and confidence of the BQYEZ.

In this price point we have behemoths like 7hz Zero Series and Tangzu Wan’er, and they still stand the test of time due to the evolutionary tonality that they brought to the budget IEM scene.

Or is it a technically capable IEM like Moondrop Chu series and 7hz G1?

(3) Where does the BQYEZ BQ10 stand?

TONALITY

Let’s start with the tonality of BQ10, which I think is the strongest point of the BQ10.



SOUND: SUBJECTIVE

The overall signature of BQ10 is natural warm. It has a decent number of bass to offer, that does extend to a point which gives the mids a bit of warmth. The treble is on the safer side of things for the most part, but there is a subtle elevation of the upper treble which gives it a certain enhanced psychoacoustic flavour that increases detail perception.

The tuning is unique, and I haven’t seen this kind of tonality in budget IEMs. This reminds me a lot of Softears Twilight (Not comparing, not even the slightest). This is the main reason why you should listen to this, IEM even if you decide to go with other IEMs.



SUB-BASS

The sub-bass of this IEM is not great. There is a softness that goes well with the rest of the frequency, but it is not close to being proper for a bass-head or anyone who likes sub-bass. It can reach deep, but the authority and rumble weren’t that well controlled. Especially with these two tracks.



I use this track with almost all my IEMs to test the authority of the sub-bass and how well they can control the low-end. This track makes it so easy to judge an IEM’s sub-bass performance.


I use this track to check the actual presentation of subbass that the IEM will reproduce in most cases if there is enough low-end information in the files.



MID-BASS

The mid-bass on BQ10 is extremely good. There is an analogy in nature in the presentation that makes it super addictive to listen to. The attack and decay are very natural and not fast enough to give it a digital feeling. The thing that comes to my mind after listening to BQ10 is how naturally rich and full it is. On the contrary, the details and resolution are not that great. The textural information can be felt missing for the most part and can overtake the mid-section a bit too.



I use this track to test two things, 1. The thump, attack and decay of the bass get a full projection by this track revealing all the hidden features 2. How the bass affects the mid-range, if it is making the lower-mids too thick or scoop is making the mid-bass lean & lifeless.


I use this track to test the absolute terminal point of the IEMs bass. This song pushes the driver so hard that even the slightest bit of impetence can be noticeable. The low-end and upper-mids are very pronounced in this song, indicating how fun an IEM can be if it is pushed to the limit.



LOWER-MIDRANGE

Lower midrange means a lot to me. It bridges everything in the music, from timbre to tonality, everything for me depends on a lot in the mid-range. Especially lower-mids where a lot of instruments that I like live. Male vocals on the BQ10 are amazing. It will give you warmth, forwardness, fullness & chesty voice. Zero sense of thinning or artificial nasalises. It is not neutral though, and people sensitive to bass might find it a bit too much at some point. The ornamentation might not be the strongest point, but it sure does exude a good tonality to make me forget the trade-offs.



I use this song primarily to check the lower mids, it gives me a great sense of amplitude. Slightly scooped and elevated lower mids can make this song very different.


I use this song primarily to check for the ornamentation like resolution, details and texturing.



UPPER-MIDRANGE

The upper-mids also exude a great sense of safer quality in the tonal characteristics. The edges are defined but not pushed in front, maintains a very well refined across the range. Never felt harsh or coarse. Enough is detailed and articulate. Seriously, there is nothing faulty about the tonality of BQ10 in the whole midrange area. The female vocals are not that sparkly and shiny, but witha good sense of resolution and airiness.



I use this song to test the presentation of female vocals, which gives me a solid sense of the tuning of the IEM.


I use this song to get the sense of ornamentation in the upper registers. Texturing, details, trailing edges etc.



TREBLE

Treble on BQ10 is not that great to begin with. This is not what I can say refined. Sometimes the tone gets abrupt in the flow. I love quality treble, but this is not one of them. The other factors like speed and transience are good though. Most of the time, good quality recordings sounded coarse and unrefined.



This track is the holy grail of treble testing. This track can tip the IEM apart and present you the treble qualities in a plate. Where every aspect will be visible in a vivid fashion.



TECHNICALITIES

BQ10 is not a technically capable IEM. The soundstage and imaging are not great. The resolution is surprisingly great, but I would not buy it for the technical qualities. There are way better IEMs like Tachjhim Bunny at lower cost.


CONCLUSION

This IEM might divide audiophiles, some might love it to death, but some might not get the hang of it. The sole reason you should get this IEM, is the midrange. And I recommend this IEM to someone who wants a different tonality from the general budget IEM options.

All Comparisons are done on my YouTube Video

Hello everyone! I'm happy to see you here again with another review. Today I am going to review the BQEYZ BQ10 (DSP mic version). The BQ10 was sent to me in courtesy of BQEYZ in exchange for my honest review.

Disclaimer​

As mentioned at the beginning, I received the IEMs from BQEYZ in exchange for my honest review, but still – my opinions about the IEMs are personal and written based on my own experience with them, and I was not paid for this review.

What's in the box?​

In the box you will find:

• Carrying case.
• 2 types of silicon ear tips.
• Type C DSP Cable.
• The IEMs themselves

Let's break it down.



The carrying case feels nice, it is round, pocketable, it has plenty of space and a place to store more ear tips or a dongle (which you don't really need here, but you might in the 3.5mm version). Overall, nice carrying case!

The ear tips included are good, they are made of silicon, and they feel very smooth. One type is wide bore, and the second type is regular. Both were comfortable for me and felt good on my ear.


Let's face the truth – the included cable feels cheap. To me, it feels like a KZ cable, at this price point I think it is not acceptable. But there is a good DSP chip to save the day, and I didn't hear any noise or hiss there, which is very good. Maybe this is the compromise you need to make to get that. I have not tested the mic of this cable, but I can say that the buttons are clicky and work well.



Build Quality & Fit and Comfort

The building of this IEM is good, the front is made from metal and the back of it is made from resin. It has a nice shape that slightly resembles the human ear, and I could wear them for long. The nozzle size is also not very big, which makes it easy on the ear.

Now, let's talk about the sound!

In Terms of Sound


Have you noticed it? Yeah! I have finally received my IEC 711 coupler. You can find the measurement here.

Let's talk about the tuning of this IEM. This is interesting to me, because I liked an IEM with this exact tuning, but here – something was off. The bass seems like there is a lot of it, but this is not a "good" bass, for me at least. It feels like it steals the show from the midrange, the treble also sounds off and missing.

And no, this tuning in general is not bad, I really liked another IEM with this exact tuning philosophy, the ISN NEO 3:



https://squig.link/lab/avishai/?share=BQEYZ_BQ10,ISN_NEO_3

But yeah, this comparison is not apples to apples. But still, it is enough to make a point. The execution of this tuning here doesn't meet my expectations.

Sub-Bass​

The sub-bass, which covers the lowest frequencies and often delivers the rumbling sensation rather than distinct sounds.

The sub bass of this IEM feels missing to my ears. There is not a lot of it, at all. To me this is very bold, I am a person who enjoys tons of sub bass, but here I think even sub bass haters would crave for more of it.

Mid-Bass​

The mid-bass, where the bass becomes more distinct and perceptible, is equally well-executed. In this range, you hear kick drums and some male bass vocals more clearly.

The mid bass of this IEM does not meet my expectations; it bleeds into the midrange, feels uncontrolled, not natural, Something there feels off. But there is a fix I have found for this, and it's name is EQ, that addresses this exact problem I have with this IEM, and I will talk about it later in this review. But overall, I did not like the bass of this IEM.

Mids​

The mids are the home to most instruments and vocals.

The midrange wasn't done so cleanly, I don't know how to explain it exactly, but I feel like I was missing something the whole time. I was missing the balance in the frequencies. Although the instruments still sounded good, it didn't feel as natural as possible. Female voices felt relatively behind, and in general it felt like the bass was stealing the show from the other frequencies, which is a bit annoying.

But for solo singers or spoken words, where the main sound is the singer vocal, this IEM provide an intimate listening experience. This is the best use case I found for them, to be honest.

Treble​

The treble, which captures high-pitched sounds like cymbals, violins, and higher synthetic tones, adds brightness, sharpness, and sparkle to the music. However, excessive treble can lead to harshness or fatigue.

The treble of this IEM is not the strongest part of it. It is a little muted, to a point I wonder where it is. It feels missing, and I am not a treble head, so it could give you an idea. The main focus of this IEM is on the lower frequencies, so this could be the reason why the treble feels "hidden".

Technical Capabilities​

The technical capabilities of the IEM are OK. The imaging doesn't stand out, it is very mediocre. The soundstage feels congested and intimate, in some songs it bothered me, and on some the intimate feeling was actually good.


I know I wasn't very positive about this IEM (and I hope BQEYZ will improve it in their next model!), but as I said, there is a fix, named EQ:





Look at this beautiful graph!

I have tried so many EQ settings, I played with it until I got a result that I liked.

Let's break it down.

What I did was first boost the sub bass (because yeah, I like it!), then I took the mid-bass back a little to make it sound cleaner, then I matched midrange to Harman, and the boosted the upper midrange in order to put the female vocals more "forward". and the result? Impressive! The IEMs took the equalizer excellently and brought impressive results, all without spending an extra buck. I don't recognize this IEM anymore! If I was to review this IEM with this EQ, my opinions of it were completely different. Since I cannot, I will just give you the opportunity to try it by yourself and judge. Here are my EQ settings for easy copy:

Preamp: -3.8 dB

Filter 1: ON LSC Fc 100 Hz Gain 4.0 dB Q 0.500

Filter 2: ON PK Fc 300 Hz Gain -4.0 dB Q 1.000

Filter 3: OFF PK Fc 1000 Hz Gain 0.0 dB Q 1.000

Filter 4: ON PK Fc 3500 Hz Gain 3.0 dB Q 1.000

Bottom Line​

The BQEYZ BQ10 are equipped with a high quality DSP chip, I didn't have to turn up the volume too much to reach a high volume level with them; very high-quality silicone ear tips, especially for this price pint. Regarding the sound, personally, I was less impressed. I think it would have been possible to put less emphasis on the mid-bass, and make the bass cleaner and let the mid-frequencies shine. What is more, the advantage of having a DSP cable is that you can easily EQ the earphones, and since there is a pretty high-quality DSP chip here, you can make strong changes and still not raise the volume level excessively, which is a big advantage for these IEMs. However, there are many competitors in this price range, and if we consider that the cable itself doesn't feel the best quality (which can be forgiven because it has a high-quality DSP chip, but still…), it puts them in a bit of a problem for me. I would say, if you like a lot of mid-bass, sounds that aren't very forward, and calm treble, they could be right for you. In my opinion, I enjoyed them more with the EQ I did to them, since it fixes all the complaints I had about them.
I am sure that BQEYZ do have many other good sets, and if you want to buy specifically an IEM of BQEYZ, I would recommend you checking out other models that might have better reviews.

What do you think about them? And what do you think about my EQ profile? Please let me know!

See you in my next reviews.

This hobby is an escapist's dream. Escape from daily routine and distress that's causing you via something as sincere and everlasting as listening to music. I believe that the power of music is still not fully understood since it works in mysterious ways. Allow it to do its magic on you and let your worries dissolve in melody.

Having had the possibility to try so many different sets in a relatively short time I felt obliged to go ahead and express my gratitude by trying to help some lost souls out there, just as I was when I first stumbled upon this weird hobby about wired earphones – so yesteryear! … I thought. Possibilities are seemingly endless and only by getting to meet the right people did I manage to jump onboard the train heading the 'right' direction without getting off-track thousands of times along the way. Make sure to understand the helping person's preferences and you too can find your footing and hit the ground running in no time.



This will be a fully stripped down version of my reviews that I will use for stuff like the BQ-10 where I simply and frankly do not see the point of spending half a day to get this all typed up and edited and adorned with photos. I am cutting everything and skipping directly to the graphics while offering an explanation as to why the set landed where it did. Finally, a quick summary and boom, I let you go on with your day.

Keeping it transparent is key, so to kick it off, I ought to mention this IEM was sent to me by BQEYZ Official Store on AliExpress in exchange for my review. They have no influence on what I write. And as always, I am grateful for the opportunity. All impressions were written using the stock USB-C cable and stock M-sized tips. It goes without saying that it is better on a 3.5 cable and driven by a quality DAC/AMP, but that sort of defeats the purpose of the IEM – a cheap entry into the hobby.

THE THOROUGH GRAPHICS

By now, most of you have come across these playful graphics of mine. I have received so much positive feedback on these that I dare not leave them out going into 2025!


The BQ-10 is a slightly warm IEM to my ears, but this will depend on the song and a very specific treble range that might make it much brighter and mildly fatiguing. There won't be much of technicalities to talk positively about – it's not to be expected in this price category.


It remains close to the center of the quarter-circle playground. It takes a slight lean towards basshead qualities and it is because of bass and occasional treble spikes that come across with no hesitation and bite uncomfortably that I see this as an energetic listen instead of a laidback one.


On these three scales, there is no forgiveness, they tell it the way it is. Good thing I did not include the Good to Bad scale, that one is particularly honest and savage, but I digress. The BQ-10 leans thicker, is mildly slow and prefers musicality over technicalities. But these three qualities tell nothing about the overall listening experience, so let's extend our research to my Six Basic Traits.


Here we start to see how the set deals with some of the most important aspects. Starting with comfort, the BQ-10 is thoughtfully ergonomic, medium sized, and lightweight, so I can't see too many struggling with it. Isolation is okay, but it does not do the best job in sealing the outer ear – very subjective, since no two pairs of ears are equal. Bass is middling at best and carries little information or depth. It gets bloated and clumsy with quicker bass lines, but to be fair, most of these ultra-budgets do. The kick can impress with its quantity, quality not as much. The low midrange is still a slightly veiled mess, which might be more or less apparent based on listener's preferred genres, sensitivity in this area, and their hi-fi mileage. Vocals are nothing to write home about, but not too digital nor shouty nor sibilant. These won't make you listen attentively for those recording slip-ups in your favourite Adele performance, neither will they bring a tear to your eyes in deeply emotive performances. Treble is a weird one. It can feel quite laidback and calm … until it does not. Then it comes out swinging and spares no harshness. It is on the drier side which should help it in quicker tempo songs, but sadly does not. Rapid cymbals and hihats are nothing but a blurry pudding. It does crawl back some ground by being decently balanced or cohesive. Ultimately, that's not too helpful as it is a cohesive performance of lackluster individual categories.

THE CONCISE SUMMARY

I am sure it was quite clear before in my Cloud and Frost reviews that I am a big fan of what BQEYZ is doing, since I feel they bring great looking, high-quality, well-tuned products to the market at competitive prices. That was why I was truly excited to see how the BQ-10 does. To my disappointment, it is not the BQEYZ I have grown to love and stays far behind in magic, resolution, and overall refinement. Nevertheless, it is a fun product and one that newcomers to this hobby would probably find impressive, but there are so many things to be had at such low prices nowadays and even against its peers the BQ-10 does not compete favorably. This one is better avoided. I recommend saving up for any of the other BQEYZ instead.

Thanks for reading and stay wonderful.

Sound​

---

Bass:​

• Sub-bass: The sub bass goes low and provides a pleasant rumble without being too boomy and taking over the rest of the sound. It's well bodied, has satisfying rumble and well defined that makes electronic and cinematic music sound engaging.
• Mid-bass: The mid bass is fast, tight, punchy with good amount attack and decay delay, providing weight to kick drums and bass guitars without being on your face or muddying. Rock, metal, and EDM benefit particularly from this tuning. It's firm but never gets out of control.

Mids:

• Lower-mids: Lower mids are full and warm, rendering male vocals and instruments such as pianos and cellos rich and earthy.
• Upper-mids: Upper mids add some additional emphasis, so female vocals and lead instruments stand out without ever sounding harsh. Strings, horns, and percussive elements sound quite lively adding to the IEM's engaging character. Everything is nicely placed vocals and instruments are present but never overwhelming.

Vocals:

• Male Vocals: Male vocals are full-bodied, yet full of life, with a slight hint of warmth that makes them full in the mix. Baritone and tenor voices carry with them a timbre that works well in vocals-focused genres, such as jazz and folk.
• Female Vocals: The female vocals sparkle bright with clarity but retain a smooth and airy feel. There is no harshness to speak of, and hence, the BQ10 are suitable for extended listening sessions comprising vocal-forward tracks.

Treble:

• Lower-treble: Lower treble smoothly imparts cymbals, hi-hats, and violins a nice crispness without being too sharp. You can feel the hits of the hi-hats because of its well extension.
• Upper-treble: Provides openness and sparkle that is in line with the generally perceived airiness of the signature. Micro-detailing from an acoustic recording or live performance does emerge organically, and there's a sense of space around them. However, the clarity can be sharp to sensitive ears. Treble sensitivity may expose you to edginess in some tracks, which I have experienced as a treble sensitive listener while undergoing extended listening sessions.

Instruments:
Separation between instruments is good, allowing many layers of the track to breathe well. Plucks on guitars, snare rolls, and their synthesizer details sound well-textured enough to allow immersion into any genre to sail well.

Soundstage & Imaging:
The soundstage on the BQ10 is wide & spacious, giving a good sense of openness that makes the music feel more immersive.
Imaging is nice, provides a 3D like sensation and that's why one can easily distinguish where instruments or sounds are from. Instruments or sounds, this also makes them good for gaming.

Dynamics & Technicalities:
These IEMs can manage small and large volume changes well. There are nuanced subtleties delivered naturally, and if a song has a large dynamic change, the BQ10 plays it in an energetic and lively manner. The resolution is excellent value for money, the sound clarity and texture is good for the price

BQEYZ BQ-10 Review: Responsible Fun​

BQEYZ is an experienced IEM maker, located in China. They specialize in building price-competitive earphones and cables and have a habit of using novel or uncommon driver configurations. We recently covered the Frost, a hybrid-planar IEM made my them and absolutely loved it. Today we’re looking at the BQ-10: a $30 dynamic driver IEM that attempts to hit all the right notes for as low a price as possible.

The BQ-10 can be purchased from BQEYZ’s official AliExpress storefront, here, for $29.99

About My Preferences: This review is a subjective assessment and is therefore tinged by my personal preferences. While I try to mitigate this as much as possible during my review process, I’d be lying if I said my biases are completely erased. So for you, my readers, keep this in mind:

• My ideal sound signature would be one with competent sub-bass, a textured mid-bass, a slightly warm midrange, and an extended treble.
• I have mild treble sensitivity.

Testing equipment and standards can be found here.

The Big Picture​

Pros:

• Solid construction
• Comfortable cable
• Eartip variety
• Expressive midrange
• Harman-tuned treble

Cons:

• Unfocused mid-bass
• Middling ergonomics
• Below-average passive isolation with stock eartips
• Medium-sized eartips are awkwardly-sized

Tech Specs​

• Driver: 12mm PET Dynamic Driver
• Impedance: 40 Ω
• Sensitivity: 113 dB
• Cable Standard: 0.78mm-2 Pin
• Termination: 3.5mm

Sound Signature​

Sonic Overview:​

The BQ-10 is tuned against the Harman Curve (and is thusly gently V-shaped) and delivers expressive, subtly-warm mids, dynamic treble, and solid bass. It sounds organic and transparent with a medium-width sound stage. It layers well compared to its price-point peers and generally remains controlled with a natural timbre.

Sonic Breakdown:​

Treble: Songs used: In One Ear, Midnight City, Outlands, Satisfy, Little One, Show Me How To Live (Live at the Quart Festival), Bittersweet Symphony

In its pursuit of “neutrality”, BQEYZ tuned the BQ-10’s treble to be present, but not forward. Treble is paired evenly with the upper midrange, save for a few jumps here and there to highlight vocal detail and instrumental separation. I quite like how the BQ-10 is able to sound detailed and “airy” without being overtly bright or sharp. Little One’s lonely speculars are captured somberly in the distance while the track’s vocals drift on by. Bittersweet Symphony’s stacked treble elements are resolved reasonably-well, but not without some minor smudging in the upper treble. This is a side-effect of the BQ-10’s less-aggressive treble tuning and is generally in line with other Harman-tuned IEMs in this price range.

Midrange: Songs used: Flagpole Sitta, Jacked Up, I Am The Highway, Dreams, Too Close, Little Black Submarines, Bohemian Rhapsody, Cash Machine, Chasm

The BQ-10’s midrange is the centerpiece of its sound signature. Vocals prominently place themselves in the front of the mix and are staged with clarity and focus. Cash Machine and Bohemian Rhapsody respond well to this level of lyrical focus. Male vocals are especially well-captured by the BQ-10, owing to its lower midrange warmth. Female vocals, such as those in Chasm, are clear but somewhat weighed-down.

The BQ-10’s midrange does resolve a fair amount of detail, but doesn’t manage to grab the final bits of micro-detailing and texture. Its subtle warmth lends its mids substance without sounding bloated. The electric guitars of Little Black Submarines rip across the soundstage with presence and direction. Raw tone and weight are captured nicely with this style of tuning, nicely reproducing The Black Keys’ intended “wall out sound” effect.

Bass: Songs used: Moth, Gold Dust, In For The Kill (Skream Remix), War Pigs (Celldweller Remix)

This isn’t a bass-head IEM, and BQEYZ never claimed it was. It sports a solid bass presence without bringing the lower register too far forward. The BQ-10 pairs its well-weighted mid-bass with its warm lower mids cohesively, though not with as much shape and tactility as I would like. This doesn’t really impact its ability to, say, articulate the bass guitar in Moth or War Pigs (Celldweller Remix), but does make Gold Dust’s bass lines softer than I’d like.

The BQ-10’s sub-bass rolls off around 50Hz, but not so severely that it cannot produce a few helpings of rumble. The aforementioned Gold Dust, while somewhat lacking in punch, did have a satisfying level of sub-bass-induced rumble. In For The Kill was delivered in similar fashion, though its bass lines did sound somewhat clipped at their lowest. Given my less-than-stellar fit with the stock eartips, this may be solvable with aftermarket accessories.

Packaging / Unboxing​

The BQ-10’s packaging is informative, compact, and protective. It is no-frills and serves its purpose well. Some brands will sell $60 or $70 IEMs with far less packaging, so even this level of protection is welcomed.

Build​

Construction Quality​

The BQ-10 has plastic shells with a faux-aluminum brushed finish faceplate. Its nozzles are metal and feature a simple mesh debris filter. The shells are light, but not hollow-feeling. On the top of the shells you can find the 2-pin connectors which are slightly recessed to add stability to the cable’s connection point.



Its cable is serviceable for an IEM in this price bracket. It features a simple twist-braid and smooth black plastic shells for the 3.5mm termination and 2-pin connectors. The termination has a decently-implemented stress relief block, but the Y-splitter does not. The cable also does not feature a chin-cinch.

Comfort​

Disclaimer: comfort is a highly individual metric — no two people will have the same experience.

The BQ-10 is comfortable, but does not seal particularly well with its stock eartips. I can use it for very long listening sessions, but ultimately I find myself dealing with a lot of intrusion from outside noise sources. Again, this is something I could tackle by tip rolling (testing 3rd party eartips), but doing so would not be reflective of the out-of-the-box experience you might get with the product.

Accessories​

Inside the box you’ll find:

• 1x Semi-hard carrying case
• 6x sets of silicone eartips

For $30, how much more could you ask for? Not much, I’d recon. The second set of eartips were a nice surprise, as some brands only include one set for IEMs that cost twice as much. The BQ-10’s case is barebones, but functional. It features a “cargo net” style divider that can be used to store a small dongle, spare cable, or adapter. Should you need to store spare eartips in the case, there’s space for that too.

Comparisons​

1: 7HZ Eula ($30)

The Eula has a warmer, less-energetic midrange and lower-treble with a brighter upper-treble. It has a similar amount of sub-bass as the BQ-10, but greater sub-bass extension. The BQ-10 has a more expressive vocal range, but the Eula has a more pronounced and shapely mid-bass. The BQ-10’s overall sound signature sounds more organic and even, while the Eula is brighter and more exaggerated.

The Eula does not come with a case, but it does come with a pretty nice cable. The BQ-10 has a good carrying case, but a less-refined cable. Overall fit-and-finish is slightly better on the BQ-10’s shells, but the Eula has better ergonomics and eartips.

2: Tripowin Vivace ($29.90)

The Vivace is a cooler, more neutral IEM. It features a slightly elevated treble, relative to the BQ-10, with a more recessed lower midrange and less-emphasized bass. It features better overall separation and layering, in the lower-register, though some may find its presentation lacking in weight. The Vivace is the more analytical and mature of the two, while the BQ-10 is oriented more towards casual listening and “fun”.

The BQ-10 trade blows with the Vivace when it comes to accessories. The BQ-10 comes with a case while the Viviace does not. The Vivace has a sturdy, ergonomic cable that feels more robust in the hand than the BQ-10’s cable. The BQ-10 is constructed nicely, but so is the Vivace. Neither IEM features a great passive seal for me, but the Vivace has smaller shells and deeper nozzles, so I generally get a better fit with it over the BQ-10.

3: KBEAR KB02 ($40)

The KB02 is a brighter IEM with a less prominent mid-bass and more prominent sub-bass. The two IEMs have similar levels of sound quality, though the KB02 does articulate sub-bass a little better. The BQ-10 has a fuller, richer sound signature that suites fans of mid-centric IEMs better, while the KB02 will certainly be the preference for listeners who want a brighter, leaner sound with a slightly enhanced emphasis on resolution.

The KB02’s increased price seems to have equipped it with a better suite of accessories, sans case. It features more, and better, eartips. Its cable is likewise more refined and ergonomic. I was able to achieve a good fit with the KB02 easily, while the BQ-10 required much more tinkering. The KB02’s lack of a case is a point against it, and ultimately makes it (virtually) a $50 or $55 IEM after a case purchase.

Conclusion​

The BQ-10 is a solid budget offering from BQEYZ. It is easy to drive, warm, articulate, and bass-friendly. It features a complete suite of accessories and offers good value for its low asking price. But, while it does give you quite a bit for a mere $30, it isn’t a giant-slayer. The BQ-10 is a solid cheap daily for those who don’t wish to spend a lot for a fun, V-shaped sound signature, but not a replacement for pricier, more-refined IEMs.

Who This is For​

• Audiophiles seeking warmth and bass on a budget
• Those who enjoy fun-tuned dynamic-driver sound
• Listeners who prefer a shallow-fit IEM

Who This isn’t For​

• Those seeking reference sound
• Audiophiles who are sensitive to bass control and shape
• Listeners who want bright, highly-transparent IEMs

As always, happy listening!

Disclaimer:​

I’m more of a Tech head than audiophile and I use Youtube Music for 99% of my listening. Take everything I say with this in mind and please don’t come after me for not having refined taste. This is purely from my silly little point of view. I was also loaned this pair for free to test and play with but all opinions are of my own with no guidance given whatsoever.

Gear Used:​

Streaming Platform: Youtube Music Premium (Bitrate: 256kbps AAC & OPUS)
Dongle - Mobile use: Fiio KA11
DAC - PC use: Letshouer DT03

Box:​

The BQ-10 box is a modest affair with no frills which I can appreciate. Inside the box you’ll find the IEMs themselves, the included cable inside a relatively common style of carrying case but solid nonetheless with a stamped BQEYZ logo on it and the included eartips of various sizes.

At this price range the inclusion in the box are more than adequate for me, the clamshell zipper style hard shell case they included that’s fairly common feels practical and robust and there’s also enough room for a dongle or two in the mesh pouch inside so if you tend to flip flop between type-C and lightning dongles like me then you won’t have much of an issue here.

Build:​

The brushed aluminum design on the shell is honestly pretty tasteful to me. They market the pair partially as gaming IEMs but i’m glad that BQEYZ didn’t lean into the gamer aesthetic too much. Will it turn gamer and audiophile heads when you pass by at the local LAN cafe? No, probably not but you can sit down in a regular cafe without turning heads as well which I’d argue is a good thing for the most part.

The inner shell of the IEM is a semi-translucent glossy black plastic that has some ergonomic details on it but like any pair your mileage will probably vary if these will work for you. They do however get pretty shiny and greasy after a while so you’re going to want to wipe them down after an intense round of gaming if you’re sensitive to that kind of thing. Also the cable included is a nice thin silver twisted pair that wears very nicely even for spectacled folks such as myself. They won’t mess with the fitment of my glasses and also don’t rub in any weird way.

Sound:​

While they are nothing to write home about they definitely sound pretty decent for the price although if you’re a bass you may want to take a step back from these considering that I found it lacking a little in that department. Which also leads me to wonder why they’d market these as gaming headphones. Stereo imaging and sound stage are decent so they’ll probably be useful in gaming in that regard but the lack of bass might also make you miss footsteps and other low sound cues and the brighter sound might make gunshots sound ear piercing but since I'm not much of a sweaty FPS player myself I really can’t really confirm this myself.

Gaming aside tho the brighter feeling sound these give off does make acoustics sound livelier such as in Weak (Acoustic Version) - AJR and Wake Me Up (Acoustic) - Aloe Blacc however the flip-side that if you like listening to the more belty and louder side of artists then these my come across as a little grating to you in certain parts especially at volume. The BQ-10 also seems to depreciate in the detail department especially at lower volumes. I tend to listen at lower volume when I’m just working to avoid distraction but they tend to sound significantly more bland in that area which makes it even more distracting but this is obviously more of a use case thing.

Nitpicks:​

The L and R indicators of the cable are oddly located on the visible side and not on the inside which just looks weird to me to be honest. It looks worse to me in general and will also probably fade faster since it’s on the outside. There’s also no included chin strap bead thing on the cable which makes it a little harder to keep and not tangle on itself and it will tangle every now and then which can get old incredibly quickly.

Final Thoughts:​

Would I recommend these to my more gaming oriented friends? Probably not since most gamers I know are also bass heads. Am I going to recommend these to my music loving friends? Not immediately, but if I know that they like to listen to more folk and acoustic music then I might tell them to give these a try. Ultimately the BQ-10 is a pretty decent pair of IEMs and includes everything you’d want for something in this price bracket as long as you know the sound profile you're getting into.

But remember the best audio gear is the one that makes you enjoy your music the most, regardless of what a stranger on the internet says.

Thanks for reading!

The product that will be featured in this review is from the audio company that I really admire since late 2010s as one of their products does really impressed me until now that it was so well-tuned with good technical performance as if that it wasn't belong on its intended market segment where it was situated but rather on higher tier at that time. We are talking about the BQEYZ and its highly regarded model, the KC2 and to this day, there are still some people who really have some good feedback and leave some lasting impressions about that product.



As we all know until now, BQEYZ has not released a product under $30/£26 since 2020 with the introduction of the first model from their Season series, the Spring. And finally, they released their latest entry-level product and what we have here is the BQEYZ BQ-10 and it has a single driver configuration but it has some unexpected added twist on it.



BQEYZ implemented a large 12 mm dynamic driver in a dual-chambered structure with newly-improved PET (polyethylene terephthalate) diaphragm that is known for its malleability, high tensile strength and some resistance from thermal and chemical reaction. The PET diaphragm along with the oxygen-free copper coil will deliver a deep and textured impression on its low frequency and then, clear and well-extended high frequency.



The driver was then encapsulated in a composite shell chassis consisting of resin material on its cavity base and a CNC-milled aluminium alloy faceplate which was anodised and brushed to give that one-directional pattern of its glossy finish surface with new logo etched on it. The shell sizes are of a medium size and their design is inspired from their previous models, the BQEYZ Summer and BQEYZ Topaz. It has a 0.78mm 2-pin as its interlocking mechanism for its detachable cable.



When it comes to wearability, this set offers a comfortable fitting into my lugholes as I conduct a long listening session that I don't encounter any listening fatigue or some sort of discomfort due to the weight of the earpieces are quite well-balanced as it is stuck and sealed firmly. The passive noise isolation of this one is pretty good as it was able to block some unwanted external noises from the outside.



Seemingly that BQEYZ is taking a different direction on this one as aside from offering a standard termination end on its stock cable, they also opted to offer a USB Type-C DSP variant but first, I will describe its overall build quality. The cable is called BQEYZ C01 and it has an oxygen-free silver-plated copper in parallel construction which offers a smooth and stable transmission of audio signal and it is somehow flexible and has a decent resistance from entanglement. Since this is a DSP-type cable, it has a built-in DAC chip inside and it also has an HD microphone with small physical hardware console with basic media buttons at the right part that can be used for playing music, voice command over a video game or receiving calls. As for the information about its DAC chip, it uses a KTMicro one, probably a KT0210 which has DSP for advanced audio processing functionality like EQ, range compression and nose filters, and it also integrates a USB 2.0 functionality that can support a full-speed mode.



As for its product packaging, like all BQEYZ sets, it offers a substantial amount of accessories that were bundled into its packaging box.



These are the following contents that were included inside of its packaging box:

• Pair of BQEYZ BQ-10 IEM transducers.
• A DSP stock cable
• Three (3) pairs of atmospheric ear tips in different standard sizes.
• Three (3) pairs of reference ear tips in different standard sizes.
• Carrying case
• Paperwork like Q.C stub and user's manual.

Since this is a DSP-Type cable, it supports devices like smartphones, laptops and tablets as long as it supports USB audio and it is also fully compatible with all known software OSes like Windows, Linux and Android that can decode up to 24-bit 96kHz on PCM format only.



When it comes to its sound profile, the BQ-10 has a mild U-shaped sound profile which has “warmish-neutral” tonality for how all the frequencies were presented at almost equal level and somewhat in a neutral manner across its sonic spectrum.




LOWS/BASS:

Certainly, it has a very balanced bass response with a fairly moderate amount on its sub bass presence while having an adequate texture on its mid bass section to give that sufficient note weight on some instruments and vocals. And overall of its bass response, it conveys a punchy, tactual and a tad ring out sounds of it.

The sub bass grumble and reverberation that were generated from instruments like drum machines, synthesisers and low tuned double-basses are fairly felt to its resonance depth. The quality of mid bass texture on this set will deliver that groove, dense and ample fullness on bass-clef instruments and some male vocals. Bass guitars sound raspy and sombre while the double-basses have a broader and sonorous sound on them, and bass kick drums have a pounding and resonant sound on every stroke on its drum head. The male vocals like basses and bass-baritones, have this almost natural timbre as they are known for their rich and deep resonance sound as they have this dense and wool-like sound from their singing voices.


MIDRANGE:

Quite a balanced, clear and sufficiently rich sounding, that's how I perceived the general sound quality of its midrange. The midrange of this one will be more versatile to almost all types of vocals and some instruments will sound full and rich with an organic manner particularly on percussives, brasses and strings.

On the male vocals, baritones of types will sound smooth, warm, steely and rich as it affects the tonal characteristics of its subtypes from light baritone to noble baritone registry, while the tenors have a brassy, spicy and a bit bright sound with some heft and volume on them that spinto, dramatic and heldentenor types will sound natural and well-bodied voices, and then the countertenors have a velvety and tender sound from their distinguishable falsetto vocal projection. As for female vocals, contraltos sounds full bodied as they have that rich, plush and smoky tone from their chesty vocals, mezzo-sopranos have that copper, velvety and a tad piquant vocals on them, and the sopranos have creamy and sweet vocals as they sound quite captivating to my ears.

Regarding instruments on how they sound, almost all of them sound very natural with a nearly correct tonal colour for each instrument. Strings instruments like guitars, cellos and violins, they sound balanced, lustrous and sweet respectively while the brasses with the likes of trumpets, trombones and horns, in a corresponding order, are producing a full, rounded and clear sound. Then on woodwind instruments, piccolos sound clear, concert flutes sound graceful, clarinets sound melodious and saxophones have mild and rounded sound. And finally on percussives, snares hits harder as it has that preciseness of its sound while tom-toms have that rounded, sustaining and warm resonance on its sound, field drums have that stately sound as it has full-bodied and a tad gleaming sound and then on kettledrums, they sound heavy with an added resonant on them.

As for pianos, they sound more balanced as they have a sweet, rich and ample warmth tone on them.


HIGHS/TREBLE:

Clearly that treble response of this one is on the smoother, balanced and quite airy as it has a mild accentuation on the upper-mids up to presence treble on pointing out the clarity and definition on vocals and notational attacks on instruments while having a non-harsh, a minimal amount of piercing and an absence of shrillness on its overall sound.

As I mentioned that it is quite airy and given that this is a dynamic driver which makes it even more impressive, it can produce a sufficiently airy treble extension with a good amount of harmonics along with an enough intensity of its sparkle. Cymbals sound lustrous with some added glistening tone on every stroke while hi-hats have that short sustaining and buzzing sound, a bell-like sound on glockenspiels and an ethereal sound on celestas.


SOUNDSTAGE, IMAGING AND OTHER TECHNICALITIES:

The perceived head stage of this one projects a fairly expansive sound field as it has a reasonably width span on its lateral points, a fairly good height and immersive depth within my aural sphere. It presents an atmospheric-like on its stereo imaging with good layering of frequency tones from instruments and vocals with a fairly clean separation on them.

The coherency of its driver is pretty consistent on delivering a fast transient response particularly on the feedback of its bass quality and clarity on the overall sound. The resolution capability of this one is fairly resolving on how it highlighting a solid presentation of varying loudness on its macro-dynamics on both choral and instrumental lines while the its micro-details has a good definition on extracting nuances, subtleties and grains from an audio track like reverb tail, vocal ends and attack notes on instruments.


PEER COMPARISONS:

HIDIZS ST2 PRO

• HIDIZS latest entry-level product with similar driver configuration and also in the same product profile.
• It uses a smaller dynamic driver with a composite diaphragm made of PEEK and PU material and it was also encapsulated in a compound shell structure consisting of resin and metal alloy.
• Its packaging box is loaded with accessories like ear tips, a carrying case pouch and even an adapter.
• The included stock cable is actually better than BQ-10’s DSP cable while it is also constructed with high purity OFC, it utilises an ESS flagship USB DAC which has more support on audio formats like DSD and higher sample rate up to 384kHz.
• The ST2 PRO has a V-shaped sound profile as it has more boomy and authoritative bass response, a recessed but warm midrange and then a bright and airy treble response.
• As for its technical performance, this set is quite pretty average from intimate sound up to less resolving resolution capability particularly on micro-detail retrieval.

TANCHJIM ONE

• One of TANCHJIM’s sets with a comparable product profile with BQ-10 as it has a single driver and DSP chip on its cable.
• It has a dynamic driver with composite diaphragm consisting of PEEK and PU material and then encased in cylindrical metal alloy shells.
• As usual for a TANCHJIM product, it is fairly packed with accessories as it offers two types of ear tips.
• It uses an unspecified DSP chip on its USB type-c cable for audio processing but like the BQ-10’s DSP Cable, it can decode only up to 24-bit/96kHz of PCM format.
• It has a U-shaped with a more warmer tonality if it is compared to the BQ-10 as it has a similar mid bass texture but it has more clearer sub bass presence, a bit more recessed yet warmer midrange and a tad more gleaming treble response.
• Regarding its technicalities, this set has more intimate head stage, a bit unrefined layering of its soundscape but still offers a decent separation on its two-dimensional stereo presentation of its imaging with a bit less resolving on its micro-dynamics.

In conclusion of this product review, I'm quite excited when I obtained of an information that BQEYZ will released a more affordable entry-level product as for the past three year, they release a number of products which were usually price at over $100/£82 and now at last, they release a product which is now price at under $50/£41 that will be more affordable to some budget-conscious audio enthusiast who want experience a BQEYZ-style of tuning. While this set is quite different compared to the other previous BQEYZ sets as it has a different take on this product as it appears that this one will caters towards mobile users that uses a typical modern smartphone which majority of these devices doesn't have a headphone jack feature by implementing an audio chip inside of its USB type-C which offers a clear and detailed sound quality from an efficiently-designed IEM earpieces with good quality driver that are able to deliver it. All I can say is that this set is indeed one of the price-to-performance ratio products out there on how it provided a fine sound quality on both tonality and technical performance.

The BQEYZ BQ-10 is now available on some selected e-commerce stores, you can check out these non-affiliated links that I have provided.

BQEYZ BQ-10 review and comparisons
.
The BQEYZ BQ-10 (29.99 USD) is a very pleasing, warm-sounding IEM that lets you enjoy the music and forget about anything else.
.
This was sent to me as part of a product review tour in my country conducted by BQEYZ Audio.
.

Thank you, BQEYZ Audio, for letting us experience your products.
.
The packaging is efficient and easy to open; it includes a nice and usable carrying case, two sets of eartips, a manual, a cable, and the IEMs themselves.
.
Power handling, sensitivity, and dynamics:
.
I'm happy to report that the 12mm dynamic drivers used on the BQ-10, which are bigger than the normal 10mm drivers, handle all the power I throw at it easily; my ears are the limiting factor here; it sounds very clean from bass to treble at very loud volumes, louder and cleaner than what I'm used to. The sensitivity is slightly above average. There is a sense of ease and high dynamic headroom and dynamic range even at loud volumes, and the tonality doesn't change going from low to high volumes; this is great!
.
Synergy:
.
The BQ-10 is not fussy when it comes to pairing; it can be paired with anything without any problems, but of course, the better sounding the source, the better it would sound. For this review and comparisons, I used the very neutral-sounding Topping G5 DAC/Amp, the stock cable, and the stock eartips.
.

Sound signature:
.
Warm-neutral; it sounds bassy-warm overall with neutral midrange and highs. The necessary rise in response in the upper midrange, called the pinna gain, is a very mild 7.5 db, making this IEM very non-fatiguing to people who are sensitive in that area. The peak at 8 KHz in the graph is a measurement-related artifact, but I still perceive some mild coarseness in the upper treble.
.
Technicalities:
.
Average; the soundstage and imaging performance are average. The instrument decay has average perceived duration; the instrument separation is also average. The BQ-10 will not impress you with its technical performance, but it is not necessarily bad because the trade-off with this is that the listening experience is very unfatiguing, even on long listening sessions.
.
Compared to Moondrop Lan (40 USD):
.
The Lan is more neutral than the BQ-10; it sounds leaner overall and more accurate, and the upper midrange is more forward-sounding. The imaging, staging, instrument separation, and sound holography are better with the LAN; however, the tonality of the LAN might cause fatigue to some people (not me). If you want warm sound, get the BQ-10.
.
Compared to Fiio FD11 (30 USD):
.
The Fiio FD11 has a similarly warm lower midrange and bass to the BQEYZ BQ-10, but the upper midrange in the FD11 is more forward, and I hear some instances of shouting with the FD11 in that area. In terms of staging, imaging, details, and separation, the FD11 has the edge, but in terms of tonality and non-fatiguing sound, the BQ-10 is better.
.
Compared to Tripowin Piccolo (35 USD):
.
The Piccolo is more neutral, with a leaner overall sound than the BQ-10. The piccolo has a more forward upper midrange, and on rare occasions, I hear some mild shoutiness in the upper midrange. In terms of upper treble extension, both are not the most extended, but I find the BQ-10 better in this regard due to it not being masked by the peak in the upper midrange with the Piccolo. In terms of separation, the Piccolo is better, but for fatigue-free, long listening sessions, the BQ-10 is much better.
.
Compared to TangZu Waner SE (18 USD):
.
The Waner SE has lesser build quality, but in terms of sound, it is very neutral; in fact, it is the most neutral in this group, the closest to what I imagine what neutral sound is. The Waner SE has leaner and more neutral bass compared to the bass-boosted BQ-10. The Waner SE has more forward but well controlled upper midrange presentation. The Waner SE has more upper treble extension, giving it a more sense of airiness to the sound. In terms of staging, imaging, separation, and details, the Waner SE has the edge, but if you like a more analog, warm, and bassy sound presentation, get the BQ-10.
.

Pros:
.
Outstanding dynamic range
Warm-analog sound
bassy sound
non-fatiguing sound
very comfortable to wear
nice carrying case
.
Cons:
.
Average technical performance

.
Conclusion:
.
The BQEYZ BQ-10 may not impress you with its technical performance, but the warm analog sound presentation and the use of 12mm dynamic drivers, which gives it an outstanding dynamic range, made the BQ-10 one of the most unique budget IEMs released of late, and for that, the BQEYZ BQ-10 earns my high recommendation.
.
Happy listening, Cheers!

Build & Design​

The build of the BQ-10 is incredible. It has an ergonomic build, with its lightweight, yet awesome looking metal faceplate made of aluminium alloy faceplate via the “Brushed Process”, which adds durability and elegance.

Cable​

The BQEYZ BQ-10 comes in four variants of cables; a 2.5 mm, a 3.5 mm, 4.4 mm and a DSP version. I received the DSP version and used my DUNU Titan S2 4.4 mm cable to test it alongside the DSP version. My review of it is solely based on the usage of the awesome 4.4 mm cable; I added a part about the DSP cable at the end of my review.

Fit & Comfort​

The BQ-10 is extremely comfortable to wear, due to its lightweight & ergonomic design. Moreover, it provides a good & comfortable seal.

Tip-Rolling​

Tip-rolling is essential with the BQ-10, as the stock tips aren’t good enough to bring out its true potential. I used the DUNU Candy Tips during my review.

Sound​

Bass​

The bass of BQ10 is clean, enjoying and does not bleed into the lower mids, which is surprising considering its price.

Sub-Bass​

The sub-bass has ample quantity of rumble and depth. It is not earth-shattering, but it is enjoyable, and the listeners will surely enjoy it. The sub-bass is in no way subtle, rather pronounced and engaging. It is not boomy, nor muddy.

Mid-Bass​

The mid-bass is thick, hard-hitting, and clean. The performance of the mid-bass will attract the mid-bass lovers and general listeners. The mid-bass has good attack and is punchy; it is also well-defined.

Mid-Range​

The mid-range is enjoyable, airy, natural sounding and has clarity. You can properly hear all the instruments, alongside the vocals of the singers.

Male Vocals​

The male vocals of BQ-10 are rich, full-filling, but a little laid-back. It also felt a bit warm, has a smooth tone, and pleasant timbre. There is good stage presence of the male singer’s voice.
Songs of John Denver were pleasing to listen to and I lost myself in his songs. I loved “Annie’s Song” & “Take Me Home, Country Roads” tracks on the BQ-10.

Female Vocals​

The female vocals have good clarity, warmth, smoothness, and richness. It is pleasing and emotional to listen to female vocals on the BQ-10. Due to the expansive soundstage, the vocal presence is awesome, and does not get overshadowed by instruments either.
Moreover, it is airy, making it engaging to listen to for hours an end.

Treble​

The treble is immersive, defined and clean. It is not fatiguing, not harsh, and balanced. Moreover, the treble is lively, rich and has nuances; with no sibilance. The cymbals and hi-hats sound crisp.

Instruments​

The instruments' separation is awesome, and clean. From the acoustic guitars to cello to violins, everything sounds clean, full-bodied, separated and has their own presence in the tracks. String instruments are produced intricately, and with great details. The cymbals and hi-hats are also clean, bright, and crisp. Moreover, due to some warmth added to every part of the tracks, and instruments, the listening experience is engaging and fun. Even electronic sounds good. I loved the instrument presentation in the song “Born, Never Asked”.

Soundstage & Imaging​

The soundstage of the BQ-10 is incredibly large and expanded. It’s depth, width, height, and airiness are on another level. I was able to get an out head feel with this. Moreover, the clarity is outstanding; enabling the listener to properly distinguish between different instruments even with such a prominent bass.
The imaging is good and immersive as it lets the listeners precisely and individually distinguish the instruments.

DSP CABLE​

The DSP cable is okay at best. The IEM loses its satisfying hard-hitting mid-bass, the rumbly & deep sub-bass. It loses the clean and soothing vocals; it also becomes harsh & fatiguing. The female vocals are forward, but loses energetic and sensational feel. Moreover, the loss of details in instruments & nuances alongside the newly gained harshness & loudness in the vocals. Male vocals sound okay, but the loss of musicality & other bits are not worth it.

Conclusion​

The BQEYZ BQ-10 is a fantastic IEM that offers a warm, engaging sound signature with a powerful bass response. Its spacious soundstage and precise imaging create an immersive listening experience. While the stock tips may not be the best, tip rolling can significantly improve the sound quality. Moreover, the DSP cable version is okay, but I would recommend getting the 3.5 mm or the 4.4 mm (for a balanced output). Finally, the BQ-10 is a great choice for music lovers who appreciate a well-balanced sound with a focus on bass and detail.
