BQEYZ Topaz

Disclaimer:​

The concerned IEM is the BQEYZ TOPAZ; although being a bit out of date, its internal piezo technology makes it quite intriguing.


At last, I get to review a product that BQEYZ graciously decided to provide me.


The review will be impartial and entirely truthful, nevertheless.


I’m simply a person that enjoys testing out various IEMs and DACs and loves to listen to music a lot. I’m not an audiophile.


Thus, while I won’t be reviewing it in highly technical terms, I will try to explain it.

BQEYZ Topaz Tech Specs:​

• Impedance: 32ohm
• Sensitivity: 108db
• Frequency Response: 5hz – 40khz
• Cable Length: 1.2m
• Pin Type: 2Pin Connector (0.78mm)
• Plug Type: 3.5mm
• Driver Unit(S): (1) Dynamic Driver + (1) Piezoelectric Driver

BQEYZ Topaz Packaging:​

The BQEYZ Topaz packaging is quite complete, in myopinion:, a high-quality box with all the accessories you need and a nice-quality cable included.


Inside, we find various accessories, such as:

• Storage bag
• 4-Core OCC Silver-plated Cable 3.5MM (Available in other terminations)
• 6 pairs of tips
• Cleaning Brush
• Manual and Warranty

BQEYZ Topaz Design/Build quality:​

The BQEYZ Topaz IEM is really well made. The faceplate is made of 5-axis anodized aluminum, and the body is made of high-quality resin. I must say that I like the design; it conveys robustness. The resin allows you to glimpse the enormous 13mm driver coupled with the piezo inside.


The nozzle is made of metal and has large dimensions, but with the right tips, it should not create problems. One breathing hole on the faceplate and three others on the opposite side are visible on the Topaz. I haven’t come across any information about the driver’s use of them. The included cable is very good and is also available with other jacks. The tips should work for most customers, but trying aftermarket tips is always a good thing.

BQEYZ Topaz Built-in technology:​

The BQEYZ earphones have been famous for their piezoelectric technology. Topaz is equipped with the second-generation piezoelectric ceramic driver with nine layers paired with a huge 13MM LCP DD.




What is meant by “piezoelectric” is the characteristic of certain materials, which is known as “piezoelectricity.”


The ability of some crystalline materials to polarize—that is, to produce a difference in electrical potential—when they undergo mechanical deformation and, conversely, to deform elastically in response to an electrical voltage is known as piezoelectricity.


An audio speaker known as a piezoelectric uses a unique piezoelectric crystal that is coupled to a moveable diaphragm to “generate” sound.


Being my first headphones equipped with a piezoelectric driver, it is difficult for me to describe it precisely, but I would say that I like the result much more than many DD+BA combinations. In my opinion, the sound is more pleasant and less cold.

BQEYZ Topaz Comfort/Fit:​

Despite having a somewhat traditional style, the BQEYZ Topaz causes me some positioning issues. Nothing major; just experiment a little to get the ideal seal. It’s now simpler to locate the ideal position once I updated the tips to the Nicehck 07 White model. Comfort is total once on, even after a few hours.

Initial sound impression:​

I could definitely feel some energy coming from the BQYEZ Topaz, but I wasn’t initially impressed by its sound. On more difficult trails, they appeared balanced but a bit unclean. I burned it for fifty hours at a high volume. I know a lot of people believe it’s pointless, and they are probably right. Most likely, the hearing and mind adjust.

I’m not listing the tracks because they’re too many, but the BQYEZ Topaz is suitable for all genres due to his W-Shaped and balanced tuning! My impressions are given using just the original accessories.


After the hours of burnout, the situation seems to have definitely improved and lived up to expectations. He gets a little slurred on very complex tracks. I don’t recommend them with Rock. The tuning that BQYEZ Topaz achieved seems to be well balanced, with a slight emphasis on low frequencies (only if the track requires it). The mids are quite present but slightly veiled, while as regards the highs, they are on par with the rest, warm and not harsh but with good detail. We could certainly have been more daring, but this way they can certainly please a lot more people.

Bass​

The bass is strong, punchy, quick, and clear with the BQYEZ Topaz. The sub-bass is easily sensed in the ear canal, practically tangible if the track calls for it. It’s not a set for bassheads, but I have to admit that it’s rather enjoyable.

Mids​

Even if it lacks a hint of brightness or airiness in this region, the mids are not so far back; rather, the voices are distinctly well-represented, and the tone is more fitting for masculine voices than feminine ones. They seem a little flat on certain songs, as if there’s a hint of silkiness lacking. Nothing major, particularly in light of the fact that this is just my own view.

Treble​

The highs are consistently enjoyable, never tiring, and incredibly smooth. Without going overboard, the macro and micro details are decent given the tuning; they’re not remarkable, but they may definitely appeal to a much larger audience. It would have been nice to have had a bit more air and brightness because I can personally handle much higher frequencies.

Soundstage and Imaging​

I’d venture to say that the outcome is great! He does not go excessive. However, the result is still pleasing; even though it’s intimate, I can still tell which instruments are which. Regarding the image, the track plays a major role. You will experience some congestion if the music is particularly complex.

Comparison:​

vs EPZ Q5




The EPZ Q5 is currently one of the best single-DD IEMs on the market. It offers a very respectable sound experience for a decidedly low cost. The Topaz has a more balanced, smoother tuning and is probably more suitable for different genres. However, it seems that on slightly complex songs, the congestion is less on the EPZ Q5. For its price, it remains the best entry-level buy.


vs MS3




The Hidizs MS3 costs a little more than the BQYEZ Topaz and is also a much newer model. Its general performance is better; macro and micro details are very present; voices are well represented; and the bass is impactful, even if slightly slower. The image is more defined, and the soundstage is decidedly wider. They are two decidedly different products, but both are good.


vs DZ4




The Letshourer DZ4 is positioned at the same price, and the technology inside is one of the most interesting of the last period! W-shaped tuning but requires a certain source with some power to stand out best. Despite everything, the performances are in favor of BQEYZ Topaz. In complex tracks, they perform better, but the overall tonality is also more consistent for the genres of music I’ve listened to.

Conclusion:​

I’m now able to claim that I tried and enjoyed my first pair of piezoelectric IEMs! I must admit that I was taken by surprise by the quality of the BQEYZ Topaz headphones, which I also received to review. Every hour that goes by, the topaz sounds better in my ears; perhaps I’m just getting used to their sound. They are an incredibly adaptable set that work well with nearly any style of music. Their performances are unquestionably better than what they are asking for; the accessories are flawless and the build is excellent. After a little tip rolling, I was able to overcome the placement issue that was causing me problems in finding insulation.

Where to Buy:

• Official BQEYZ Aliexpress

Source(s)

• Truthear Shio
  • Only source I have that has a 4.4 balanced output.
    • The Topaz that was borrowed to me is using the stock 4.4 cable
  • Doesn't have the best synergy since the Topaz is a little warm already, but it still smoothens out the peak a little bit.

Ear tips

• Acoustune AET07
  • Fairly neutral ear tips with a decently hard stem for a comfortable fit.

Packaging

• Borrowed unit, so I can't comment too much on the original packaging.
• Stock cable are EXCELLENT, can compete against more premium offering's stock cable, might even be better than Letshuoer's already great stock cable!

Build Quality

• Lightweight.
• Solid build quality

Fit

• Nozzle width is average and length is a little short.
• Shell has a large fin on it, may cause the fit to be not as deep, but overall it is quite a comfortable experience even after long hours.

Tonality

• Warm, mild V-shaped.

Bass

• Surprisingly, the sub bass is quite prominent, but the mid bass isn't lacking in any way too.
• Has very good rumble and impact, decent slam, depth, texture and definition.
• Overall, it also has a really nice fullness and physicality to it, making the bass sounds bodied.
• However, the speed is average and the decay is a little bit slow, causing it to sound a little mushy sometimes.
• It is also not the most well controlled bass, which bleeds a little bit into the midrange but not necessarily a bad thing.
• Good amount of bass, very satisfying but never too overpowering.

Midrange

• Midrange is very warm, full and thick, most unique aspect of the IEM in my opinion.
• Male vocals sound very lush and bodied, and quite forward with very decent texture as well.
• Female vocals on the other hand, is a bit more pushed backward, and sounds somewhat veiled and muffled.
• Instruments sound extra thick due to the heavy note weight and density.
• This warmth throughout the midrange does affect the clarity of the midrange heavily, causing it to be very colored.
• Overall, the midrange is a hit or miss, you'll either really love it or hate it due to that special touch of warmth.
• Unfortunately, I did not like it as much as the timbre isn't natural to my ears.

Treble

• Treble is relaxing and laid back overall but there are sharpness in certain frequencies.
• Due to the peaks, there will be a ringing or zinging sensation for certain tracks, but it is not often for me.
• It also lacks a fair bit of airiness since it doesn't extends well into the upper region.
• However, details in the treble department is decent.

Technicalities

Resolution

• Resolution is decent and competent for the price despite having such a warm and relaxed signature.

Soundstage

• Soundstage is decent, staging is on the wider side but quite average in terms of depth.

Imaging

• Imaging and accuracy is alright, I am able to tell where the instruments and vocals quite well from left/right but struggle a little in other directions.
• Gaming:
  • Apex Legends: Similar situation, I'm able to judge the sound of footsteps and gunfire in terms of left and right really well but not other directions and distances.

Separation

• Separation and layering is average, instruments and vocals are a little mushed together in the lower end but layering is quite decent on the upper end.

Conclusion

• Overall, I think that the BQEYZ Topaz is truly a unique, special, but also niche offering.
• Unfortunately, I did not enjoy the Topaz as much, as the timbre mostly sounds way too off for me, but there are a few people that I know who really enjoy this type of very smooth, warm, and lush signature.
• However, I can safely say that this is definitely one of the, if not the most special IEM that I have tried in a while, but it is not up to my preference.
• If you have the chance, this is very well worth to demo to see if this signature is suitable for you, as this is truly one of its kind especially for only $89.

Thanks for reading!

𝐈𝐧𝐭𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧:

BQEYZ is no stranger in the chi-fi scene with their well-received season-themed series of IEMs such as the Summer 1 & 2 as well as the Autumn. They are also known for sporting a piezo-electric driver on their IEMs which is somewhat rare in the sea of IEMs commonly with Balanced Armature and Dynamic Drivers as well as the recent boom of Planar Drivers.
Today BQEYZ offers the Topaz(A type of Mineral) for the $100 price range sporting their signature piezo-electric driver and a Liquid Crystal Polymer(LCP) driver akin to other popular IEMs in the price segment and see how it performs for the asking price and whether or not it deserves to receive similar recognition to its predecessors.

𝐃𝐢𝐬𝐜𝐥𝐚𝐢𝐦𝐞𝐫𝐬:

I don’t consider myself as an audiophile or an enthusiast, therefore the terminology and the overall review will be more mainstream.

• I like to keep my reviews simple without too much confusing and lingo
• This review set is a part of a review tour and was sent free of charge in exchange for an honest review. There is no material or financial incentive for me to do this review. I guarantee no exchange has been done by both parties to influence or sway my opinions on this product.
• My thoughts and opinions are of my own. My experience will entirely differ from everybody else. The contents of this review should not be considered factual as this hobby heavily leans on subjectivity. YMMV.

𝑯𝒖𝒈𝒆 𝒕𝒉𝒂𝒏𝒌𝒔 𝒕𝒐 𝑴𝒔. 𝑬𝒍𝒍𝒆 𝒁𝒉𝒐𝒖 𝒂𝒏𝒅 𝑺𝒊𝒓 𝑬𝒊𝒋𝒊 𝑹𝒐𝒎𝒆𝒓𝒐 𝒇𝒐𝒓 𝒑𝒓𝒐𝒗𝒊𝒅𝒊𝒏𝒈 𝒂𝒏𝒅 𝒂𝒍𝒍𝒐𝒘𝒊𝒏𝒈 𝒎𝒆 𝒕𝒐 𝒑𝒂𝒓𝒕𝒂𝒌𝒆 𝒊𝒏 𝒕𝒉𝒊𝒔 𝒓𝒆𝒗𝒊𝒆𝒘 𝒕𝒐𝒖𝒓𝒊𝒏𝒈 𝒈𝒓𝒐𝒖𝒑 𝒂𝒏𝒅 𝒕𝒂𝒌𝒆 𝒂 𝒍𝒐𝒐𝒌 𝒂𝒕 𝒕𝒉𝒊𝒔 𝒓𝒆𝒗𝒊𝒆𝒘 𝒖𝒏𝒊𝒕 𝒘𝒆’𝒍𝒍 𝒃𝒆 𝒍𝒐𝒐𝒌𝒊𝒏𝒈 𝒂𝒕 𝒕𝒐𝒅𝒂𝒚.
𝐏𝐚𝐜𝐤𝐚𝐠𝐢𝐧𝐠:
The Topaz comes with a no frills, compact split-type box that has the name of the product, brand and other text. The back of the box sports the technical specifications for the IEM and other text that aren’t really relevant to most folks.

𝐔𝐧𝐛𝐨𝐱𝐢𝐧𝐠:

Upon opening the box, another flip up cardboard is there to greet you with a BQEYZ branding and tagline.
Removing the flip up cardboard reveals the IEM themselves and the included circular zipper case with branding containing the 4-core silver cable(2-pin, 3.5 termination) with some paperwork.

Underneath the foam holding the IEMs are the 6 normal bore eartips with all the common sizes (S,M,L) and 6 Wide-bore tips having the 3 sizes. The wide bore tips are somewhat a tad bit smaller compared to the other type of tips provided. It also comes with a termination plug cap, a BQEYZ branded velcro strap and a small brush for cleaning the unit.

Overall a pretty nice unboxing experience despite having a less flashy packaging and a more compact box compared to its competitors in the $100 price range.







𝐁𝐮𝐢𝐥𝐝:

The Topaz has a universal IEM fit made out of an outer aluminum face plate and a translucent black resin shell for the rest of the body. The outer aluminum shell has hints of gold trimmings and a Topaz text on the left driver and a BQEYZ text on the right. Both the O and Q are used to cleverly hide vents on both drivers neatly.
This unit has quite a number of vents with a total of 4 vents each driver. The plug used for the removable cable is a common 2-pin. The nozzle is golden colored and has ridges to help the tips be more secure. It also has an engraving on both sides near the vents to indicate which is the Left and Right driver with an L and R.
I found the unit pretty lightweight but does not feel cheap on the hand. The cable is pretty soft and nice in the hand for a stock cable while the ear tips are pretty uneventful. Both work and do what they are supposed to do.





𝐈𝐬𝐨𝐥𝐚𝐭𝐢𝐨𝐧:

It isolates well given that you get a good seal with the Topaz. I would also like to note that the occlusion effect(it’s the annoying muted/in your head feeling often associated with in-ear gears) on the Topaz is less than your normal IEM which I find very nice since I’m very sensitive to that sensation. I think it’s due to the substantial amount of vents present on this product compared to others I've tried so far.

𝐂𝐨𝐦𝐟𝐨𝐫𝐭:

This section of the review is very subjective and varies person to person, but I do find it comfortable and is able to sit in my ear for long periods of time without much adjustment needed.

| 𝑺𝒐𝒖𝒏𝒅 |

𝐁𝐚𝐬𝐬:

The bass on the Topaz is definitely the star of the show. It’s textured, well controlled and it has a body. The subbass is more prominent than midbass which offers a nice rumble and warmth to the overall sound whilst the midbass is less prominent but still noticeably present. Midbass bleed is very minimal seeing as this doesn't push midbass front and center.

With this kind of bass some people especially to those accustomed to the Harman-sound or prefers midbass over subbass may find this set to be quite slow on the attack and somewhat soft especially on more modern music that is catered towards midbass.

𝐌𝐢𝐝𝐬:

Mids here are warm and has body and doesn’t sound thin. It may not be as forward as the lows but they’re no slouch either and perform very well. Vocals are warm and lush with nice texture. Male vocals aren’t dry sounding and are more forward than the female vocals. I do think it could’ve used a little more extension to the mids. It’s not that the mids are lackluster, it’s just that I think a little more extension would be nice.

𝐇𝐢𝐠𝐡𝐬:

This is the part of the sound that takes a step back. Despite not being as pronounced as the other frequencies, the highs are decent, offers okay-ish detail, and isn’t shouty. I do however find them quite sibilant. However similar to the mids, I do find the highs would have benefited heavily with a little more extension and sparkle and some would even find this set somewhat dark sounding. I understand that this product is supposed to be a more laid-back set, I don’t find it would hurt to have more extension on both highs and mids.

𝐓𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥𝐢𝐭𝐢𝐞𝐬:

Imaging and layering-wise is good in that I can accurately pinpoint sources of sound during playback. Staging is very good in my opinion; the Topaz offers a very unique presentation that I never experienced in IEMs I’ve tried prior to this review. The perceived stage is more open and wide and doesn't feel like it’s congested like most IEMs. The Topaz has surprisingly nice technicalities for a laid-back set and for the price.

𝐂𝐨𝐧𝐜𝐥𝐮𝐬𝐢𝐨𝐧:

I adore this set for what it offers and its asking price. It’s hard to find a unique sounding set in a price point crowded by Harman-esque tuning.This set is warm and full-bodied which I definitely enjoy especially for laid-back listening. It being such a unique experience, this set stands out from the pack of IEMs under the competitive $100 price range.

BQEYZ Topaz ($89): A Gem by name and sound



Topaz


Intro: BQEYZ has produced many models, but not so many that each new iteration seems to fall directly upon the previous. With a seasonal tone, I liked the Spring, Summer and other models such as one of the originals, the BQ3. I have appreciated the tonality of all; but with differing signatures. While not perfect, BQEYZ went their own decided path; eschewing the common theme of the time; which seemed to be a bright, vibrant signature to the detriment of actual quality. BQEYZ went for a smoother, more mellow signature and some did not like that. I do and recommended many of the models to those looking for alternatives to the mainstream flow from mainland China. I still appreciate BQEYZ, and the Topaz is the next iteration coming from within.

The model was graciously sent to me by Elle and BQEYZ. I am thankful for the continued support, and while this may not be an absolute new model time-wise; it is still a pertinent example at the $100 price. It is also understood that the model is mine to keep but may be asked back for at any time. Selling the unit is not cool (still) and should never happen to review samples; and will not happen here.

Unboxing:

For many, the unboxing experience is a true event. Other models I have in-house currently are experts at presentation and this makes for a true experience. Others let the unit themselves speak. BQEYZ while not too over the top lies on the more tasteful end of the unboxing experience. I am OK with that. The top lid lifts off, revealing the gray circular case on one half and the Topaz on the other. I opted for the purple and I do not regret it at all. Stunningly subdued, it exudes a certain beauty to it of quality while not shouting to you. Think of any Lauren Bacall sultry look from the shadows in a Bogart black and white movie and you get the idea. Stunningly simple in presentation and looks.

Also included are six sets of tips in S, M, L configuration with two types. One is for a more bass-oriented sound while the other is treble-oriented. Many manufacturers have gone this route and I do approve.



Build/Fit/Finish:

I have never had issues with BQEYZ quality offerings, and the Topaz is no different. Made of three pieces, the shell, faceplate and nozzle each are of different color. Coming in either black (with a bit of glitter/sheen to it) or the purple, the shell itself and nozzle are black and gold for each. The nozzle has a good lip to it, which helps keep tips on. Plus, it is not so large to make it a bear to mount said tips. With three vent holes, two on the inside directly in front of the ear nub and one centered on the faceplate among the letters (Q on the right, O on the left) there is plenty of ventilation for the 13mm dynamic driver to breathe. The black shell is also semi-translucent, allowing you to see the insides a bit.

Coming with a silver coated wire, in 2-pin 0.78mm jack formation, the overall look is one of stateliness. The cable is thick, but little to no microphonics were heard and it lays quite well, with minimal retention of being wound tightly to fit inside the circular case. No ear guide is attached to the 2-pin connection, but the cable lays well behind my ears, even with my reading glasses on (cataract surgery gave me 20/15 vision for distance!!!). To compliment the colors, gray rules the roost for the headphone jack, splitter and 2-pin connectivity. Softer in color there is a tinge of a lighter color as well; which makes for a subtly unobtrusive look.

Everything about the Topaz gives the impression of not wanting to be a bother. And it works.



Technology:

Coming as a dual-hybrid driver unit, the Topaz houses a larger-than-normal 13mm dynamic driver for the low end (and mids) along with a 9-layers piezoelectric driver. Many companies have started offering piezo drivers either singularly or as part of a hybrid system. We are now to the point where if included it is no longer a strictly new technology, and many are onto their second iterations of the drivers themselves. The BQEYZ offering works for the high end, complimenting the dynamic driver nicely.


Sound:

Summary:

Tito Puente’s Oye mi guaguanco is a vibrant danceable song, with mich going on. The Topaz highlights the ability to hit the lows with aplomb, allowing the mids of vocals and percussion instruments to shine through without too much interference. High end does come with a bit of sibilance on certain passages along with some “funkiness” in the piezo. The detail retrieval to me overshadows both concerns, making for a thoroughly enjoyable sound, with a warm slant to go along with abundant bass.

Moar:

Safari, also from Tito Puente rides a deep and rich bass line to start, which continues as the high flutes come in; complimenting each other nicely. When the bongos enter, there is very little interference as well, allowing the incoming sax quartet to play the main line without too much bother. If I had to quibble here, it would be that the bass tone does reach into the mids a bit much with some bleed; which does not allow the mids to shine on their own. The tonality of the Topaz is such, that the fun factor to me still overrides any potential problem. Plus, with that prevalence of bass, you can hear the electric bass guitar with ease. Something not all songs allow as it is predominantly a background instrument. Trumpet and sax solos come through but seem to be slightly back from the center stage as a result of the way the tone is mixed. I do still enjoy the relaxing, warmer signature; but this should be taken into consideration by some.

Moving to Kenny Burrell & Coleman Hawkins superb Bluesy Burrell album and Tres Palabras, that overlying bass comes through but is meant to with the bass cello. Always a strong point in jazz of the era, the bass sets the tone for the song and it is sumptuous. Turning the volume up on the equally superb A&K ACRO CA1000 (review forthcoming) I find the song intoxicatingly sweet. I do prefer a more mellow signature, on the warmer side of life and the combination is quite good here. Yes, that bass still semi-gets in the way; but is meant to as the line on which the song lies. Deep of reach, and with decent thump, the bass gives way to excellent clarity when the piano comes in. Strong of note, each hit of ivory comes across as quite clean, but not dry nor analytical. This is smooth jazz at its best (preferably on a 2-channel vinyl set up...), and the Topaz proves its worth across this genre quite easily. Hawkins enters about the halfway point and I stop to listen. Smooth of character, you relish his playing while knowing the limitations of the Topaz. To me, on anything, which would provide a brighter signature would ruin the whole scene, and the moment. A very good match together here.



Moving on to a much more raucous song in Feel It Still, from Portugal. The Man, and you run into the limits. A vibrant song to begin with, the high line of beat seemingly reaches the limits of the piezo, and the volume comes back down...a bit. This is such a great song with which to kick, you dare not retreat the volume wheel too much. Tolerable, but clearly present. This is also a very good song for judging soundstage. Wide and deep with excellent height you get the feeling of a vaulted ceiling. But one with very good acoustics. Moving to Dire Straits seminal song Sultans of Swing, order is mostly restored. A semi-complicated song with much going on, nothing is lost in the Topaz’ presentation. Layering might suffer the most, except for the aforementioned soundstage. As a result, the Topaz copes well with the multi-layered song. Knopfler’s voice is so good, that you can do nothing but kick back and enjoy it. That said, it is here where cymbal hits and clashes can sound a bit strained, due to the piezo I believe. Not nearly as bad as some piezos I have heard (nameless for the do not deserve to be mentioned...) but strained a bit. Another reviewer (Prime Audio, one of the best out there imho, here) mentioned that the timbre of the cymbals was off, and I would concur. That is a very good assessment of the treatment. Even with that, the treble remains very, very good, adding enough sparkle up top without becoming brilliant in texture. Evidence of this comes across on another Dire Straits song (and one of my favorites) Down to the Waterline. High cymbal hits sound very good, and when Knopfler’s guitar reaches into that realm the signature rings true. A thoroughly enjoyable moment in the song, when you might expect something less.




Comparisons:

I will openly admit that I have not reviewed much gear in this price range lately, but when called upon for this, I was pleasantly surprised that the price point remains a very viable category; especially when for many this would be a reach. We certainly need to keep that aspect in consideration. You could do much, much worse than any of the three mentioned below in my opinion.


BQEYZ Topaz ($89) v Thieaudio Legacy2 ($109):

I can remember reviewing the Legacy4 first in the Thieaudio lineup. It was (and is) and excellent unit, with much detail retrieval (more than the Topaz), and excellent bass response, even if it bled into the mids. It also ran a bit too hot for me. The Legacy2 follows that same pattern, but with a bit less clarity. On par with the Topaz, it follows the same pattern, except for the mids, which sit in a more frontal position to me. I really like the offerings from Thieaudio, and they seem to hit many points quite well.

But here, that frontal position of the mids, even if they sound cleaner; is a bit too far forward to me. I prefer the way the Topaz comes across. So, for those wanting a more natural sound, that is also laidback; the Topaz would be the choice. If you prefer a more vibrant upfront signature, that really does not offend me; then the Legacy2 would be the better choice.

It is nice to have choices.



Conclusion:

As I play Celia Cruz’ excellent La Vida Es Un Carnaval, I am reminded yet again of the deep reaching bass in the Topaz. Like a deep shine of a precious gem (yes, yes, I did that...), the bass mends the line for the signature of the song. With the punchy bass shining through, the Latin sound is unmistakable. You cannot help but tap the toes or get on your feet and dance. The Topaz presents those who like this sort of sound with a fairly well-rounded laid-back signature, that oozes with a richness in sound quality. Clarity is very good at this price, and that bass has a slower decay, which aids in lengthening the sound and thus giving the warmth provided. Providing cover for the rest of the signature, yes there is the overlap with the mids a bit; but as witnessed on this song it does not hinder my enjoyment.

With treble reach that does not bother me nearly as much as some piezos on the market, we can see the maturation of the technology. A viable alternative to balanced armatures it has developed with each new model present and I can see a future where it becomes a worthy addition to driver technology. Right now, it is quite adequate at delivering solid sound, with minimal distraction. Much like the Topaz overall.

BQEYZ Topaz ($89)​

I have always been a fan of Bqeyz. They always seem to go out on a limb to showcase newer tech. Trying new things and taking chances puts Bqeyz on the cutting edge I suppose. I have personally tried many of their budget iems as well as their more expensive sets and I’ll be perfectly honest… I’ve liked them all. The Bqeyz iem which I’m featuring today is the Bqeyz Topaz.

I wanted so badly to get my hands on this set yet just didn’t have the funds. That is until Elle Zhou of BQEYZ reached out to me and offered Topaz on a very generous discount. I am so very grateful for the gesture but obviously this will not affect my review at all. Friends…if I ever have a bias of any kind… I’ll simply tell you. You can still review with a bias so long as everyone knows that. It is nice to receive discounts and review samples but there has to be integrity and truth as the staple to an honest review. Just be honest. So as honest as I can be, there is no bias here. What I hear is what you’ll read and nothing more and everyone understands as much.

The Topaz came to me in a rectangular box with “Topaz” written across in a purplish-blue coloring. I opened the box and was to see the earphones themselves, as they sat gorgeous within some cardboard/foam cut-outs. Next to the Topaz was the round case. Nothing special but made well enough. Possibly faux leather I’d imagine. Underneath the iems is the ear tips which also rest in cut-outs inside the box. Next to the ear tips is the cable. In my case I opted for the 4.4 balanced cable. You also get some warranty stuff but… I’m trying not to bore you though so…lets move on.

Build/Design/Fit/Durability​

Look​

I happen to think the Topaz are flat out tough looking. All sleek and slick and svelte with a minimalist design which screams sophisticated, classy and confident. I’m digging the color of the set that I received. Looks like the paint on my Chevy Silverado. Just tough! I received the coffee-colored brown with golden accents version. Most certainly the Topaz are stylish with a certain debonaire swagger.

On the faceplate is a contoured & lopsided triangle with “Topaz” on one and “BQEYZ” on the other. The Topaz has nice curves and distinguished lines on the faceplate as well which is a nice touch. Elegant and Dapper in the same sentence and done in a tasteful way. The shell is a transparent black resin which has a solid feel. Up next to the light I can see through the dark plastic just enough to make out the Driver. The nozzle is nice too, sporting a golden appearance with an actual lip for ear tips and a nice metal grill.

Fit / Isolation / Comfort ​

The fit is okay… when I work at it for a couple seconds. There is some moving around in my ear to get the best seal but nothing painstaking. Also, I had to tip-roll to achieve the proper seal. I’m sure these will fit someone like a glove, but I do have to fiddle a slight bit. No worries though, I’ve been at this game a long time and I kind of expect it anymore. After playing around with the fit, the Topaz are very comfortable and lightweight and hug my ears well enough.

Isolation is about average. Obviously, the Topaz aren’t going to cancel out the world completely. Let’s put it this way, they cancel out about the same as most iems. Especially with music playing from my library. Isolation is average, I suppose. Truthfully, I don’t really think about it, but I know some of you think this is important, so…average.

Build Quality/Durability​

Bqeyz does well to create well-built iems, they always have. The material used on the faceplate is some sort of alloy metal, possibly aluminum. Also, like I said earlier the Shells are a very hard and durable Resin type material. Some say that “plastic is plastic ”. Um, this is not true. There is a difference to a shell constructed with a solid and durable type resin material and some chintzy plastic with a softer feel. I have to assume that the Topaz are as durable as you can responsibly take care of them. They aren’t cheap feeling at all, not even in thee slightest.

What’s Inside​

I love different driver technologies and now that we are seeing better tech hit the lower end of the market it is clear that we are in a great time in audio. Topaz is no exception. Bqeyz chose to use a 13mm Liquid Crystal Polymer (LCP) Diaphragm Dynamic Driver. Paired with that is a second generation Nine Layer Piezoelectric Ceramic Driver. Bqeyz have really zeroed in this tech as the Piezo is something of a hallmark or specialty of the company. Bqeyz also added a dual cavity structure which is promoted to make “Vocals airier & thicker”. We shall see.

​

Ear-tips​

The ear-tips provided are actually not bad at all. As you can see, they are differing shades of gray. Three of the pairs have a narrower bore which is denser and sturdier with a firm flange. The other set of ear-tips have a wider bore with a more flexible and flimsier flange. Both counter the additional tuning touches of each other. I have to admit that I did tip-roll to a pair of KBear-07’s and the Fiio Bass Tips (Basically the exact same ear-tips) as it seems that I always fall back on those tips. They simply fit me perfectly.

Cable​

During check-out you have the choice between a 2.5, 3.5 or 4.4 cable connection. Like I said earlier, I chose the 4.4 jack as the devices I most use are 4.4 balanced sources. The cable feels well enough made. Basically, as good as most upgrade cables. It is a 2-pin 4-core OCC silver-plated cable, white in color. It has a nice feel to it as the braid isn’t too tight and I love the contrasting accents of the cable Y-split and the jack termination.

Drivability ​

The Topaz does ok with lower powered sources as it is rated at 32 ohms and a sensitivity of 108 dbs. In my case I used the Zooaux Dongle Dac, which I use for review purposes because I really don’t have a very low powered source. Also, I’m sure anyone purchasing the Topaz will likely have a decent Dongle Dac to listen with already. Using the Zooaux I am able to get to decent volume yet with far too relaxed of a sound as dynamics and harmonic expression aren’t as full and lively. Moving to the Qudelix 5k and the IFi Go Blu there is an instantly more gratifying sound. I gravitate more toward the Go Blu paired with the Topaz. The CS Dac chip along with Ifi’s implementation of it seems to nail what I like.

Using something like the Fiio KA3 is nice as well but I did notice some very slight Piezo timbre at note ends in the upper midrange to lower treble approximately. It doesn’t sound bad at all and is easy to go unnoticed, but it was there. So, I then attached the Fiio Q1 MK2 to my Galaxy Z-Fold 4 and the sound is warmer and lusher with this pairing. There is plenty of power on high gain and I was happy with it.

Still, most of my listening was done using the Ibasso Dx240 w/Amp8 MK2 on medium or high gain and there is a nice synergy there. I found that with more power the Topaz isn’t as tampered down in the upper-mids, and I found the stage opens up a bit as overall harmonic extension increased at both ends of the spectrum. I do think that with a slight bit more power added I was able to maximize the sound to suit my preferences. If you do happen to have a lower powered source I dont think this is much of an issue as the Topaz are sensitive enough to replay well.

Quik Sound Impressions​

Burn-In​

When I first began listening to the Topaz I immediately wasn’t hugely impressed. With all the hype I was expecting a bit more, I guess. I thought they sounded nice, and I could listen happy enough, but I didn’t get that “wow” feeling. 50 hours of burn-in later and there seems to have been a refinement in the sound. It was almost as though more energy was able to crack through in different places which simply made the sound more musical and enticing.

Quick Sound Impressions ​

The Topaz has a very balanced yet lush sound with what I would call an almost relaxed W-shape sound profile. Within that relaxed soundscape is a controlled & energetic rhythm and pace. The bass is emphasized only a little bit which doesn’t cloud any other area of the mix. The midrange has a velvety and forward nature that comes across warm and full. The energy in this area has a cap to it which can hold back some shimmer in the upper midrange. There are some issues at times which I’ll explain later. The treble is balanced with the rest of the spectrum with some hints of sparkle yet remaining mostly reserved and warm but falling off with nice extension.

The sound has a snap to it, or a bite. In the same breath I call this sound reserved and relaxed. I realize these are conflicting observations. The energy on the Topaz seems to be held back to a strategic point which never spills over into chaos or glare or fatigue. There is a snappiness mixed with a certain warmth which never encroaches into the veiled or dark side of things. I’d say there is a relaxed clarity within the warmth. Restrained is the word which comes to mind. I don’t mean restrained as in… ‘Held back’ or ‘not enough’. I mean, the energy is restrained like a balloon tied up tight, to hold its form. There is a control here which finds its way into all parts of the frequency.

Bass​

The bass as a whole is represented very well in my opinion. I feel the sub-bass as well as the mid-bass have a nicely detailed and punchy sound with good clarity. Warm in tonality with a certain bold sounding agility.

Sub-Bass

The sub-bass has a slightly restrained rumble which is adequate to most genres. I still feel a satisfyingly tactile reverberation when a track calls for it. Basically, I can still feel the sub-bass. Also, there is nice texture and a layered low bass area, yet it is still not overdone at all. “I Love” by Joyner Lucas, a song from his “ADHD” album has a deep and firm vibration when the beat drops. While I would never call the Topaz a basshead iem, it still displays a low reaching and strident bass line. Granted this is an easy track for definition but the Topaz keep some good hidden authority and couple it nicely with the rest of the frequency.

Mid-Bass​

The mid-bass runs on a linear path with the sub-bass, for the most part anyways. Again, not overdone, or sloppy, or in bad taste…not in the slightest. Slam is present just not as emphasized as the bass boys would like. I know this because I do like a healthy dose of bass in my music. I grew up on rock, metal, country and gangster rap (another conflicting statement on my part), and big bass captivated me. It is something which I will always silently hope for. In a quality manner that is. That is what I came from, and I can easily say that I am perfectly content with the quantity on the Topaz.

To some, the Topaz will have too much and to some it’s too little. Like I said, for myself, my ideal for a good low end anymore is quality bass, which is tight & colored with a punchy attack and with a slight decay to add atmosphere. The Topaz get very close to that.

The mid bass has a nicely controlled decay and a sustain which lingers just enough for good presence which I feel is a nice touch. I wouldn’t call this bass slow, and I wouldn’t call it fast. Also, the attack in this region has a punch to it, not overly forceful but it is felt and heard, and it’s controlled and clean.

Bass as a whole​

All in all, the low-end hits with decent authority which does not overstep in a sloppy and bloated way. Still, the mids are affected by the bass spilling over a bit, however I think it is to the benefit of the lower mids, adding clean heft and presence to vocals and instruments.

The only other thought I have is, at times there is a slight restrained feeling in the bass. I still very much like the energy here; it has an almost round nature and comes with a detailed and textured response to most songs. The bass has a solidified tidiness or a firmness which testifies to the tuning of Bqeyz. They added just enough to balance out the spectrum and I’m glad they did. The Bass has good pace and timing and nice cadence with enough speed to carry most tracks without blurring the sound. Texture isn’t top notch and layering is decent here, as a whole…I’m a fan.

Midrange​

Low-Mids​

The lower midrange has a character of richness in men’s voices. The bass runs right into the midrange bringing an energetic warmth which dials in the hardy nature to male vocals. Note weight is nice here and I hear no muddiness or veil at all, but instead a crisp and tepid sound which is pretty well resolute.

“On My Way” by Avi Kaplan shows off his resonant baritone voice which echoes with a rotund and sonorous sound. Avi’s voice is bold and hard edged yet has an emotional dictation. Instruments like the soft acoustic guitar do get lost a bit behind the heft of his voice but I think this is by design perhaps, per the recording. There is a more open and natural sound to his voice which I can appreciate listening with the Topaz. Maybe I could use a bit more “pop” in most male vocals but all in all I hear a good presence and weightiness.

On the flipside, a male vocal like Zach Bryan on the song “Sun to Me” is much more pronounced and even edgier with the Topaz. His voice has a higher pitched rasp in his normal one-take acoustic style of country music, and this set nails it. He’s a singer-songwriter type who needs the inflection in his voice to emotionally carry the song along with the acoustic guitar as he strums with equal presence and volume. His voice is forward and has a command to it that almost breaks through to glare yet stops short of it. The guitar comes through perfectly and with a more natural timbre to my ears.

Upper-Mids​

The upper midrange walks a very fine line between too relaxed and glare. It’s in this area where the low-end warmth begins to lose its effect leaving a little bit of levity and airiness. I hear good energy in this region as female voices sound full and have some vibrancy behind them. Still there is a small lack of that “shimmer” which we talk about so often. However, shimmer or not, the Topaz carry enough kinetic amplitude in the inflection of a woman’s voice to make up for it. Softness in a breathy vocal has emotion behind it, like Olivia Rodrigo in “Traitor”. The emotional pull of her voice is not lost on the Topaz. The sentiment within the song is captured and the artistry isn’t devalued as the Topaz is able to properly convey what she is going through. At least in my opinion this was done very well.

Females in general sound very nice on the Topaz. I love the energy without the spiking shout or odd timbre which can derail a woman’s voice. Females are highlighted in a melodic way that makes me want to enjoy the Topaz often.

Glare?​

The only minor con is the few times the Topaz added just a bit more bite to my music, getting mighty close to glare. Yet the Topaz stops just shy. There is a spot within the spectrum around the upper-mid area which can almost have a bit too much grating-luster. It’s an edgy shoutiness which doesn’t sound like a controlled shimmer. I labeled this a “Con” earlier but in truth I don’t think it is a normal problem and instead a situational slight glare in the right songs. For the great majority of my library, I don’t hear this.

Instruments have a natural cadence and tone with nice clarity and energy. Granted, every detail is not brought close to the ear and perfectly illuminated. Though I wouldn’t call the midrange deficient in details. The Topaz isn’t a detail monster which is dry and analytical sounding, but rather a warm and inviting and musical iem. I would call this set a very enjoyable and euphonic sounding earphone which is empathetically musical and emotionally warm and more so caters to the casual listener.

Treble​

The treble region is more laid back as well without any real dazzle or sparkle up top. This area is taken care of by the Piezo driver which brings okay technicalities even in the face of this laid-back style. There are Instances in the lower treble where that Piezo timbre can sound fizzy at note ends, some would refer to this as ‘Piezo Timbre’. Quite honestly it doesn’t bother me but is worth noting. Extension on the Topaz at the highest regions seem to die off a bit quicker than I’d like. I think it could use a bit more air and even some vibrancy within the presence region.

Slight Issues​

There are simply some casualties of this laid-back tuning. No doubt, the Topaz is a smooth operator with a very non-fatiguing sound and the treble stays true to that. I noticed average resolution and even some details along the way. However, if a track has a lot going on, the rest of the mix can drown out the subtleties in the upper parts of the spectrum.

I noticed cymbals get muted a bit in busier tracks. Truthfully this may not be an issue to you. It all depends on what you enjoy. I don’t hear the most natural extension in the treble region but what I do like about the treble is the smooth long listening style which it caters to. Let’s put it this way, when I’m simply chillin, listening to my music, I am more apt to pick up the Topaz than something with more energy and bite up top.

Soundstage/Separation/Imaging/Details​

Soundstage​

To me the stage size of the Bqeyz Topaz is rendered just wider than intimate. The Topaz portrays an imaginary stage pretty nicely. In my opinion the tuning is not one which normally breeds an airy and open style staging, but I hear a decent size considering. Overall, the width is about average, nothing too expansive. The tuning pushes much of the soundscape forward and leverages only ear width of the space to each side. Height seems to be above average compared to iems that I’ve listened to at the price point. This height does well to add some much-needed space and headroom. As far as depth there is an adequate sense of forward and backward imagery, depending on the track of course. For the most part depth seems to aid the overall presentation and therefore is not bad at all.

​

The Stage simply has to make sense​

The stage size of the Topaz conveys what I always say that I absolutely require, that is…the stage has to makes sense. I realize this is not exactly an “audiophile” statement but… I’m no audiophile, also, I actually enjoy music. You can call me a bona-fide audio geek, I can live with that. Nothing is too closed in or too oblong or narrow. Granted this also isn’t colossal in size but there is a sense of intimate continuity and placement of the different parts within a song which gives a feeling of a partitioned off imaging to a degree. I could use a bit more air in the upper parts of the frequency or a sharper cut-off between the bass and the Mids which would help but, Bqeyz wasn’t shooting for that. Basically, it is a more concentrated stage. However I dont find the Topaz congested or cramped. It makes sense to my music being played.

Separation/Imaging​

Separation of elements within the stage varies depending on the track being played. If I choose a track which simply has a lot of congestion, then separation seems less effective and feathered together. Separation isn’t bad or under par at all. Then again it isn’t the best that I’ve heard, of course I don’t think this set is tuned to be a technical wizard…and I don’t mind that. This tuning is mostly warm and laid back and not very analytical or ultra-speedy or dry. Imaging takes a subtle hit in this regard though I would say that imaging is pretty well done. Placement of instruments and voices sounds somewhat distinct. While separation is about average there is some layering that happens and that helps distinguish different parts of the whole. Not the best but not the worst.

Details​

Okay, there is a common theme which will continue in this small section. No details don’t flood your ears-holes with miniscule subtleties, but really…who cares. Yes, there are some macro-details which sound resolved enough and highlighted enough to carry a song very well with the Topaz’s melodic and warmly musical nature. No details don’t jump out at you but why would they?

The sound has a smoothness to it and a heft to it which gives a more ardent and musically spirited expression to my library. This isn’t to say that the Topaz is devoid of any detail or is at a loss on the technical side of things. In truth I think for the tuning the Topaz is well resolved and sounds pretty darn awesome. This is a set to sit back and enjoy, it is truly melodic and ear friendly for long periods and still will resolve some details and finer nuances providing the song is not too chaotic.

*Comparisons* ​

​

Tripowin Olina (Mesh Mod) ($99)​

The Tripowin Olina needs no introduction. A standout performer around the $100 price point which is a staple in my everyday rotation. This was the brainchild of HBB (Hawaiian Bad Boy) which was supposed to mimic the sound of the Tanchjim Oxygen at a lesser price by incorporating the same driver within the Olina housing. That being a 10mm high performance Carbon Nanotube Diaphragm (CNT). My set I modded with the infamous “Mesh Mod” which smooths out the upper-mid glare and bumps up the low end a bit.

The Olina is more resolving and carries better details and technicalities across the spectrum. The bass is tighter on the Olina and has a faster and punchier initial attack. Still the low end has better presence in my opinion on the Topaz with a bit more raw texture. It’s much deeper with more of a haptic growl on the Topaz. Vocals are thicker and more robust on the Topaz as well. Timbre sounds more natural to me on the Olina however, as a whole that is. Treble extension and shimmer brighten up the Olina where the Topaz are warmer and reserved.

All technicalities, ranging from separation, imaging, details, both macro and micro and even stage width, height and depth all go to the Olina. Truthfully the Olina is almost in a class of its own in many of these categories within the under $100 crowd. Albeit some of the newer Planar iems can trade blows, but I digress. Again, note weight is more dense on the Topaz and they have a more emotional spin to my music. Also, the Topaz are much more forgiving rendering less of a peaky replay and are much easier for longer periods of listening for me.

Two different styles of replay. The two are both top performers at the price point and both for entirely different reasons. This is a matter of taste, like most iems. Do you want smooth and melodic or more technical and melodic? I personally will always have a certain affinity for the Olina which I can’t quite explain but I still love to sit for hours with the Topaz in my ears. I think fit and comfort probably go to the Olina for me as I don’t have to fidget and move things around too much for a seal. Obviously, you may be completely different. I do like the look of the Topaz a bit better but that isn’t saying much because the Olina are beautiful in their own right. In my mind it’s a toss-up and I’m very happy to have both within my collection.

Letshuoer D13 ($113) ​

One of Letshuoer’s newest iems to grace the world of audio is the D13. A single Dynamic Driver which sports a custom 13mm DLC Driver and a tiny housing which nestles nicely in my ears. The D13 comes equipped with tuning nozzles to ever-so-slightly change tonality. I have still not reviewed this set but that is coming soon. You can check out Mahir’s impressions here.

The D13 has a warm of neutral lower half of the spectrum and a more vivid and airy top half. Some people with the community have given the D13 mixed feelings, yet I quite like this set. I’d say the two are another story of differing styles. The Topaz is quite a bit warmer in tonality and more laid back while the D13 has a more sprightly and vibrant sound.

The differences between these two are pretty stark for me. Again, the Topaz has a warmer and a more reserved sound while the D13 are cooler in tonality with harder edges to notes and a crisper sound delivery. In this case “crisp” translates to more unnatural to me. The more earthy sound of the Topaz simply has a more naturally articulate tone and timbre. The D13 has more slam in the bass region yet is also less balanced sounding in the same breath. Male vocals sound thicker and fuller on the Topaz while the D13 interprets males a bit more recessed and less sonorous.

The D13 has a more forward female vocal which has a very nice and emotive sound even if they have a slight thinness. Females do have a slight recess yet still remain mellifluous and honeyed. Both give females nice texture to their voices. The D13 treble region possibly has better details yet with less reigned in dynamics and almost a less musically cohesive upper area of the mix. The Topaz are more buttery and seem to have better control and command of the spectrum…to a point. That is, the Topaz ‘can’ get more easily congested in complicated tracks. The D13’s dynamic and vivid presentation can replay edgy & shouty at times. In fact, the D13 can bring on fatigue when listening to the right genres. I don’t get that from the Topaz with any genre or music type.

The D13 has many nice upsides though. The bass of the D13 is deeper and I do like this aspect of the sound as I could use a bit more authority on the Topaz. Another aspect of the D13 which some may like is the crisper sound to vocals and instruments with a snappier attack and a quicker transient response. There are many times that I want a more energetic sound in my music without a sheening glare inside my ear holes and the D13 can give just that most of the time.

In fact, I quite enjoy the D13. One upside to the D13 is the fact that it sounds a bit more extended in the low end as well as the highs. Details float to the surface easier by way of tuning alone. The stage sounds wider and has better separation of sounds and elements of a stage. Imaging is basically a wash as both sets do well to pinpoint instruments and vocals to create a nice stereo image. Still the contrast between these two earphones is enough for me to comfortably label this showdown as simply a preference battle. To me they are more different than they are alike.


*Note: The only reason I added these comparisons was to hopefully make some distinctions against some other nice iems in the price point. I never really try to stage a showdown but more so use comparisons as a tool to help a person make a purchasing decision.

Conclusion​

People, I gotta tell you, I really do like the Topaz. I love that suede sound, that warmish ease that moves like butter through the airwaves. The Topaz isn’t too much of anything or doesn’t push the envelope at all, yet it excels in a lot. I am constantly reaching for the Topaz amongst more expensive iems when I actually have a chance at some casual listening. I want to thank BQEYZ and Elle Zhou once more for their kindness and the boldness to let their product speak for itself.

Every review I say this; please take in other reviews of this set. It is very important not to hang on any one person’s word or experience. Everyone is different, we may have different gear, tolerances, likes & dislikes. Not everyone hears the same and not everyone has heard the same gear to achieve the perspectives which they may have. All I’m saying is, please read or watch or listen to other angles.

I am not perfect; I am not the most experienced or knowledgeable and would never claim to be. Leave that to the “Audiophiles”. I am simply a man with a love of music and a constant drive to find the best way possible to replay that music. Also, I absolutely love to express my opinion and to share my experience with you all. It is so very therapeutic to define what I hear in the written word, and I love to write. Hey, maybe one of these days I’ll start to get good at it.

Thank you very much for taking the time to read my review. I can only hope that it helps you to make a decision in some way or another about some of these iems that I review. As for the Topaz, this one is a winner. Give the Topaz some time to level with your brain a bit and also some burn-in helps as well. So with that I am off, take good care everyone.

BQEYZ Topaz: The Gem to Be Loved



“Like the gem it calls itself, the Topaz offers an experience unlike the competition that makes it a precious entry in the IEM market”


Today we will be looking at BQEYZs latest release named the Topaz. Will the Topaz show honor and strength to be competitive in the under $100 market or will it just be another brittle gem to be crushed by the competition?

PACKAGING



Before we talk about the IEMs themselves, let’s take a look at the packaging that the IEM comes in.

The box dimensions are 16.5 x 10 x 4.5 CM. Sporting a split box design similar to some smartphone boxes, it offers quite the spacious box for the IEM to sit in before unboxing. The top of the box has a nice purple color with wave-like designs scattered throughout. The BQEYZ Logo can be seen on the top left and a large TOPAZ fills up most of the top.

The sides of the box are rather plain with the top half of the box having the same purple and wave design as the top. The two sides also feature text with one side including the BQEYZ logo and their tagline of “Best Quality Earphone for You” and the other side has the words “Stereo Earphone” on it.

The underside of the box contains its spec sheet and other necessary information you may want to know before opening the box like accessories. Their logo, a big Topaz, and their address are also located here.



Opening the box, a piece of cardboard with the same logo and tagline meets you. Removing the cardboard shows the IEMs themselves and the carrying pouch. I received the grey colorway of the Topaz which accentuates the very well-textured aluminum faceplate. We’ll expound on the IEM themselves further in the review.



The carrying pouch comes in a circular form. Relatively small and can really only fit 1 IEM and maybe a small dongle DAC. Inside the case comes a small cleaning brush. I wouldn’t say that this carrying pouch is all that pocketable, but it allows your cables to stay in a circular wrap when stored which I prefer over the rectangular form that can tangle up your cables. A pretty standard-looking Velcro strap with the BQEYZ logo is also included.

Under the case, the essential paperwork and warranty reside. Above that is the foam cutout for the IEMs themselves which, when removed show an array of ear tips. 12 pairs in total with one set looking to be a wider bored form while the other has a narrower bore. I personally prefer the wider bore, but I noticed that it has the tendency to scrape my inner ear. The tips are about average for what I’d expect in this price range. It would’ve definitely been nice if they had included at least 1 pair of foam tips. Comfort-wise, both tips are adequate enough for my ears. Build-wise, on the other hand, the outer part of the tips seems to be quite thin and can be easily ripped compared to other freebie tips that come with IEMs their price.

Overall, the box is quite ergonomic and spacious while keeping a very stylish design. I like the purple shade they used, but the wave design seems more reminiscent of the BQEYZ KC2 rather than the edgier design that the Topaz has. The unboxing experience was quite the treat and I commend BQEYZ for using a cut box design as I personally prefer this over the slide-down style that many other manufacturers use on their boxes. If I were to nit-pick, removing the tips from their holder was quite unenjoyable as I had to take a long tool to pluck out the tips. But a great experience as a whole.


BUILD AND FIT



The BQEYZ Topaz sports an attractive grey-on-aluminum shell with golden traces that form a rounded triangle shape at the center with either BQEYZ or Topaz written on the very center. A very creative and interesting design choice they did was to use one of the circular letters of each word (that being the Q and O) as vents. This is to me quite a creative way of integrating vents into your IEM without making it look boring or out of place. Under the faceplate is the resin housing and the golden nozzle which measures ~5mm in width and ~4mm in length. The front of the resin housing sports in total 3 vents. 1 standard-looking vent and 2 odd symmetrical vents within a rectangular dip. Whether this configuration has a big impact on the sound can only be confirmed by those willing to filter mod their particular unit. The resin also curves a wing to compensate for the shape of one's ear better.



The cable itself is a thick, 4-core silver cable, terminated to 3.5mm (although you can get a 4.4mm or 2.5mm balanced cable as an option). It has a relatively average length of 1.2m and includes a decent chin slider and a non-fatiguing ear hook. The jack is gold-plated and aluminum and includes the logo on the side. The splitter and chin sinch are colored similarly to the jack and have the BQEYZ logo on the splitter. The chin sinch is just alright and may move around over time but will be unlikely thanks to the material of the cable.

Overall, the comfort of the IEM is very hit or miss. The fit is quite loose regardless of which of the stock tips I used, and the wing does more harm than good to me as it does not “lock” into my ear as other IEMs do. This could be attributed to the wide nozzle that may or may not allow you to insert the IEM deeper into your ear.
The cable is relatively good compared to other stock cables if you’re into thicker cables as each strand seems to be as thick as a standard 2 core with a pretty large but lightweight jack. The splitter and chin sinch are also well-built and implemented.

Due to its quite odd fitting of the IEMs themselves, it has the potential to cause problems for some users. It’s higher recommended to tip roll to something you’re more comfortable with as the stock may prove to be uncomfortable for some users.


SOUND: 28.5 out of 40

Sound Signature:

• Warm L Shape with emphasis on the bass region, thick lower mids, occasionally recessed upper midrange, and occasionally peaky treble

Driving Power:

• I personally did not have any issues with driving the Topaz through the phone, but due to its piezoelectric and LCP drivers, it’s harder to run than the average single DD. Scalable but still enjoyable at less hifi sources

Bass: 8 out of 10

• Thick, punchy, and yet very well controlled and detailed bass response
• Sub bass rumble is adequate and compliments the midbass elevation very well
• Very punchy and engaging midbass kick while retaining a lot of detail
• Surprisingly does not bleed into the midrange and even compliments the lower vocals on having a lot of body in them
• Average decay but well controlled for a non-muddy or boomy presentation
• Kick drums, bass guitars, and cellos are extremely well represented with great detail and timbre

Midrange: 7 out of 10

• Male vocals are very well represented with a lot of body
• Nuances in male vocals such as raspiness and heft are also well represented
• Lower registers of string and air instruments are engaging and detailed
• Male vocals are often forward and very intimate
• The upper midrange has the tendency to sound nasally and unnatural
• Female vocals are not very well represented and can either sound distant or too warm (depending on their register)
• Upper registers of pianos, violins, and some air instruments have the tendency to sound distant and almost absent on some tracks

Treble: 6.5 out of 10

• Smooth and laid back on the lower end but can still offer a good amount of details
• Higher female vocals start to recess and have a lot of distance on busier tracks
• Somewhat blunted which combined with the prominent bass dulls the upper midrange to the presence region
• Odd sharpness and piercing in some tracks may bring out some details that feel out of place to some
• A sufficient enough amount of air that presents a larger stage
• Technicalities are surprisingly well represented despite the somewhat blunted lower treble/upper midrange

Soundstage, Imaging, and Separation: 7 out of 10

• Bass prominence somewhat hinders the depth of vocals but instruments are quite expansive sounding in the spectrum
• Height is decent and can offer a surprising amount of headroom on tracks and particularly in gaming
• Imaging is above average and can point out where instruments are most of the time except for busy/bassy tracks
• Instrument separation is average with the upper treble bump aiding in a more out-of-the-head experience

COMPARISONS

Vs T3+

• T3+ has a warmer leaning Harman tuning while Topaz is a warmer L Shaped tuning
• Bass is leaner and better controlled on T3+ while Topaz has a punchier, more engaging, detailed, and textured bass
• T3+ has a better-balanced midrange with a more forward upper midrange but thinner lower mids while Topaz has a better body on male vocals but less engaging and slightly recessed upper mids
• T3+ has a brighter treble with the microdetails being just slightly better than the Topaz. Topaz’s treble is smoother and more laid back while still retaining most of the details. Topaz is less fatiguing for longer listening than T3+
• Technicalities are a tad bit better on the Topaz but T3+ has a slightly wider sounding stage in turn
• Fit is MUCH better on T3+ compared to Topaz (personal)

CONCLUSION:

Introduction

Autumn and other seasons passed, until a new model from BQEYZ, the brand from Dongguan, China, came out. After the great success of its previous model, the Autumn, an IEMS with a single dynamic driver and an effective and innovative magnetic mechanism to fix the tuning filters, the brand is back with a new series consisting of 1 dynamic driver and 1 piezo driver. This time, the new dynamic driver is dual-cavity and uses an LCP composite diaphragm. While a new 9-layer piezo ceramic driver has been designed and adopts a new joint structure, so that both drivers can cooperate in the best possible way. There is no doubt that BQEYZ is still determined to improve its initial idea and it seems that every time it manages to take a step forward, as well as improving the price, which is a great achievement. And it doesn't just stop there, because the design remains highly attractive, offering an adequate level of accessories, a silver-plated single crystal copper cable and a nice zipped case, as usual. In the following review we will go into these and other issues in depth, as well as its sound, of course.



Specifications

• Driver Type: 13mm dual-cavity coaxial dynamic driver with LCP composite diaphragm + 9-layer piezo ceramic driver.
• Frequency Response: 5Hz - 40kHz.
• Sensitivity: 108dB
• Impedance: 32 Ω
• Cable: 4 strands of silver-plated single crystal copper, 0.06mm cores bonded in 7x7 strands for a total of 196 cores.
• Jack Connector: Choice of 3.5mm SE, 2.5mm BAL and 4.4mm BAL.
• Capsule Connection Type: 2Pin 0.78mm.
• Colours: Grey and violet.

Packaging

The BQEYZ Topaz come in a box that is blue on the front. To me they look like dunes of an unreal blue earth, seen from above. The dimensions of the box are 165x101x45mm. In the upper left corner is the brand name in white letters. Below and very large, the name of the model is written in faint brown. The back face is simple and vertical. At the top, the model name is repeated in the same font, but in a smaller size. In the middle are the product specifications (in Chinese and English). At the bottom are the brand name and the various certifications that IEMS complies with. After opening the box, there is a white foil with the slogan. Underneath and at the top are the IEMS encased in white foam, while at the bottom is the zippered case, which this time is round and pearly in colour. On the last layer are the tips and documentation. In a nutshell:

• The two Topaz capsules.
• The 2.5mm balanced cable and 2Pin 0.78mm connection.
• One set of black tips, sizes SxMxL.
• One set of grey tips, sizes SxMxL.
• One cleaning brush.
• Instruction manual.
• Warranty certificate.

The box is attractive, not too big. The accessories are just the right amount, no more, no less. The case is now round, but it's still of superior quality to other more common ones.
It's not a great presentation, I would have preferred foam tips, but the case and the cleaning utensil, which is not common in all products, are good enough. In fact, it's very reminiscent of the presentation of the Summer model and the contents are as usual for the rest of the brand's products.
On the other hand, it's available in two colours and in three plug ends (3.5mm SE, 2.5mm BAL and 4.4mm BAL), something I find absolutely essential for this price.



Construction and Design

The shape of the Topaz capsule is very similar to that of the Summer. It's true that the colours, materials and the external face are different, but ergonomically they are very similar. Although it's still a triangular shape with rounded sides and a sinuous vertex. This time, the outer face is of a different colour and material than the body, it has a metallic appearance on two levels. The outer tier is higher and the middle tier is lower, separated by a triangular gold stripe. The brand name (right) and model (left) letters are on each capsule, written in the same gold-coloured capital letters. The inner body is made of black resin with a slight transparency. The mouthpieces are metallic, gold-plated, 5mm long and 5.8mm in diameter. The protection is a perforated grille with medium-sized holes. Between the two sides of the capsule is the 2Pin 0.78mm connection, slightly recessed in the body of the capsule. They are inside a plastic oval, but the cable has no other shape than the two visible pins to fit perfectly. Near the nozzles is a protected hole. On the way to the edge is the inscribed channel lettering, barely visible. Then there is a small oval part, more recessed, with two holes at the ends, near the apex of the inner side, which serves as a fixation in our ears.
The cable consists of 4 strands of silver-plated single crystal copper, 0.06mm cores joined together in 7x7 strands, making a total of 196. The connector sleeve is a regular, metallic grey cylinder, with the marking written in white font lengthwise. The divider piece is the same style, but one-third the length. The pin is a metal ring that fits into the divider piece. The sleeves of the 2Pin connectors follow the same cylindrical shape, with a recessed ring near the cable guides. They have the channel letter written in white. The 2Pin 0.78mm connector is the classic external gold-plated connector.
As I say, the shape is very similar to the Summer model with the change of the colour, the external face and the gold-plated nozzles instead of silver-plated. Otherwise, the details are the same.



Adjustment and Ergonomics

I can't hide the fact that BQEYZ is a brand that has a path and seeks to perfect it. That's why it continues to focus on this series of hybrids with DD and piezoelectric. It's true that it has broken the saga of the seasons that ended with the Autumn and now, the new one in the series, has a different name. Although some objectives have been achieved, such as the packaging, the accessories or the cable. I also think that ergonomics is the strong point here. So why change it? Actually, it's not necessary.
The Topaz maintain the same level of ergonomics as the Summer because their shape is the same. This means that the weight is minimal, the fit is very good and the adjustment is superior. At least, in my case. I maintain that the thickness of the mouthpieces can be the critical point for those with narrower canals and the fit is shallow. As the cable is also similar, the over-ear fit is comfortable, there is no microphony and it's still a light set, which fits well, does not move and generates a high level of freedom. An earlier success that will not be changed.



Sound

Profile

I could describe the profile of the Topaz as a rising W. The first half is quite flat and reminds me a lot of the Spring 2. But the big breakthrough of the Topaz is that it manages to master the piezo driver in a way that its predecessors did not. This results in a more controlled and less unrealistic treble. Then, there is also restraint in the upper mids, generating a well-balanced profile, with a very good tuning in the first half, as usual, but this time it's accompanied by a second part that matches very well, obtaining a more homogeneous and adequate result.



Bass

The low end is very linear, but enjoys a slight emphasis on the transition from sub-bass to mid-bass. It should be noted that the roll-off from the highest point of the bass to the lowest point of the midrange barely reaches 5dB. While the bass moves in a range of less than 2dB of variation. This gives an idea of the linearity I am talking about. It also implies a deep sound, a contained, sufficient mid-bass and a fairly full and homogeneous range. But it's not all about tuning, and if there's something surprising about the Topaz, it's its technical quality. BQEYZ has managed to splendidly combine power and dryness in a great dynamic driver. The bass is tight, clean, very well controlled, but has enough power and punch to be enjoyed by a bass-lover like me. There isn't too much decay, the speed is good and the retrieval is remarkable. In this way, a level of precision and a highly effective drawing of planes and structures prevails. With these outstanding technicalities, the bass feels greedy and makes you want to turn up the volume so that it fills the scene. But even then there is no loss of control. The power is kept in check and never loses its way. It's a wise authority that knows how to keep its manners and show itself to be impeccable, even when it's forced to turn up the potentiometer or reproduce thick, badly recorded or unfiltered bass. The Topaz know how to show their class and firmness, achieving a great response in the lower area, as well as a lot of versatility. The texture is sufficient. It's usual for drier or more technical drivers to have less roughness, but here we feel a tight, delicate, but descriptive trembling, which is perceived at the first instant, enriching, even more, a range that I value highly.



Mids

The transition between the bass and the midrange is smooth in the roll-off. That implies that there is a good amount of body in the sound of the first half of the range, as well as warmth. However, the male voices are not overbearing, but respectful of the rest of the performance. In this way, they are not shown in the foreground either, which is something I would have predicted just by looking at the graph. Once again, the graphs do not show everything, and it's welcome that there are pleasant surprises in this respect. These are not midcentric IEMS, nor are they very dense in this range. The thickness of the voices is average, not too thick, not too thin. The male voices feel reinforced by the weight of the first half and the female ones by the effective emphasis of the mid-highs. They also possess a good blend of smoothness, sweetness and definition. The Topaz have improved their piezo sparkle and the subtly particular look and feel of the driver. The sound and harmonics have become more natural. But, with time and testing, you can notice its impact on the overall timbre, albeit for the better. Of course, this is not only true for the vocals, but for the entire midrange instrumentation. That mix of warmth and evolved piezo sparkle is the constant companion in this range, offering a remarkable character to the overall sound.
Once the turning point is passed, BQEYZ has managed to refine the mid-highs in a respectful manner. The enhancement there is progressive and moderate, accompanied by a somewhat early drop in control of the first treble. This also affects the mids: they possess clarity, transparency and a somewhat dry sparkle, but never overflowing excitement. In this respect, the Topaz are secure, and BQEYZ has taken great care to create a more sedate ensemble in this respect, in order to maintain overall homogeneity and balance. Thus, the mids don't feel bright and sibilance is non-existent, but a little bit of well-controlled flare could be missed. Even so, the midrange enjoys a good level of detail, richness of nuance and surpasses itself in passion, smoothness and warmth, something that brings a remarkable sense of musicality, as well as a more organic sound.



Treble

The Topaz upper zone maintains the ambivalence of the IEMS in the series. But this time with a special restraint. The critical mid-treble point has been softened and the first highs have been lowered. It still seems to be difficult to make the high notes more linear in gain in this first half and it's easier to lower the response of the piezo driver. And this is what has been achieved. There is an early control roll-off that cuts the first brightness and detracts from the sparkle in the incipient highs. You feel that point of dryness I've talked about in the mids. These are not dark IEMS, but there is a sense of dullness in the beginning. The best thing is that the characteristic peak has not only been reduced, but also softened. The piezoelectric edge persists, but it's now even more enjoyable. The Topaz have been tamed at the top end and this has consequences, many positive, some a little more unfavourable. It's not a brilliant sound, but it's a safe sound, so many enthusiasts now know what to expect. Thus, the representation of the zone is initially very fine, with subtle flashes and a quick finish. Its prolongation is more limited and its extension feels split. If the notes go further, there is a hint of that more classic excitement of the series, but enhanced. Finally, I don't find the air feel to be superior to previous models, even this extension could be guilty of a more concise and squeezed sound.



Soundstage, Separation

The representation of the scene is eminently frontal. The level of depth is good, although it's not a very three-dimensional, spatial or airy sound, nor does it become surrounding. The height is noticeable, but the laterality is not very high. In this way, the stage appears more rounded, with a certain proximity, without being overwhelming or too much on top of the listener. In this sense, it's a calm presence, which does not become intimate.
The separation is palpable, but not huge, it matches the size of the scene. Even so, I was surprised that there are details that are very visibly exposed, even better than other sets. Maybe because they are more sensitive to some specific nuances, but I must comment that it has been very pleasant to appreciate this good exposure. In this way, the sound seems richer and more enjoyable, especially in the mid-range. Perhaps this is due to the new generation piezo driver. It should be noted that this is not an analytical sound, but rather a warmer, sweeter and more harmonious sound, but it does include these good technicalities. Starting with the bass, an area in which the dynamic driver's ability in this respect already stands out. Then, in the central range, I think that the mix of this better endowed dynamic driver, together with the improved piezoelectric driver, combine a technical competence that allows to reveal details at micro and macro level, with ease, but without showing any analytical tendency. This is possibly a clear example of synergy and I think that this beneficial effect is a great virtue that BQEYZ has been pursuing and has found in this model.



Comparisons

BQEYZ Summer

Both models have a close resemblance in shape, but the Summer is made entirely of resin, while the Topaz has that outer face that looks metallic. Simply because of this detail, the Topaz seems to have a more premium finish. The cable is also almost the same and the differences are in the metal parts. While for the Topaz these parts are pure cylinders, for the Summer these cylinders are tapered in the middle and have a lighter colour.
In terms of sound, the Summer has a more pronounced W-profile, with a higher low end in the sub-bass, while the mid-highs and highs are also more excited. At first glance, the Summer doesn't have the fullness and homogeneity of the Topaz. And that's something you can feel in the mids, which are denser and fuller in the new model, while the Summer's show a more pronounced comparative remoteness. The sonority and quality of the two lows are similar. But the more restrained tuning of the Topaz gives it a superior technical point, though also less texture. That point of power in the Summer makes it more unbalanced but also more fun. Although boosting the low end does lose the audiophile advantage over the Topaz.
The mid-range might look very similar, but the greater linearity of the Topaz gives it a superior balance. The feeling of fullness, density, homogeneity and body is more accentuated in the new model and that responds to a more restrained tuning at the extremes.
The treble response is clearer and more perceptible in the Summer, perhaps the range that offers the most differences. It's true that the mids, due to the influence of these differences in bass and treble, also feel clearly different. But the upper range has an excitement in the Summer that is far removed from the Topaz. You could say that the Summer is the rogue sibling of the Topaz, while the new model is the polite child of the family. I suppose each will have its fans, but the classic mid-treble peak is a point of detriment to the overall quality of the Summer.
Mid-range detail is perceived as superior in the Topaz, while in the treble, the help of their greater presence in the Summer improves their exposure in this range. The slight midrange remoteness offers a scene, in the Summer, that looks different. It feels flatter in the Topaz and a little more oval in the Summer. This sensation gives the Summer more depth, while the Topaz image is more compact and compressed in this respect. I don't find much difference in the separation of the two IEMS, but I think the Summer's tuning works in favour of the appreciation of the distance between elements. There is more air and sparkle in them and this gives a sense of space around the elements that is not so distinct in the Topaz. The more homogeneous and compact sound of the new model results in a more cohesive presentation that brings the notes closer together.



Conclusion

I think the BQEYZ Topaz are the most rounded product in the brand's piezo hybrid saga. They seem to have been able to tame the beast here and the treble is more restrained, although you also pay a price for it. The Topaz have a balanced, calm and more homogeneous profile, which makes them a safe, slightly warm, musical and pleasant IEMS. The classic sound for hours of enjoyment. They are elegant and comfortable, maintain the same level of accessories of the brand and perfect the tuning in bass and mids with respect to the rest of the models of the previous hybrid saga. The consequence of a more controlled upper zone and the reduction of the classic piezo-sparkle is that the first highs feel slightly more subdued, something that can be the delight of some or the Achilles heel of others. It's in this upper zone that the balance is lost or the right to buy is gained. Still, it's worth noting that this is also the cheapest model in the series, which can be a great opportunity to experience the great, evolved, characteristic sound of some unique hybrids.

Tracks Used:
The tracks I have used can be found from the below playlist that I have used and generally use for most reviews...







BQEYZ TOPAZ Sound Impressions in Short:

The BASS:

The bass is quite textured and sub-bass has ample details. The mid bass packs a good amount of punch but not overdoing it or being overly prominent. The overall bass experience is quite enjoyable. In tracks like: "Fools Paradise (LP Version) – Donna Lewis" and "Chocolate Chip Trip - Tool" you can clearly enjoy the bass experience.

The MIDS:

The midrange of the TOPAZ though recessed has good amount of muscle and details. the instrument transients feel quite lively and the vocals feel quite up close and natural. In tracks like: "Anchor - Trace Bundy", "A dog named Freedom – Kinky Friedman" and "Ruby Tuesday – Franco Battiato" it’s really easy to get lost into the music as it comes with ample detailed transients, texture, excellent vocals and details.

The TREBLE:

The treble has a quite laid back representation and I felt like I could use some sparkle here. But having said that, it's quite a smooth experience with most people will enjoy.

Treble in tracks like: "Paradise Circus – Massive Attack", "Mambo for Roy – Roy Hargrove” and "Saints and Angels – Sharon Shannon" feel quite enjoyable.


The SOUNDSTAGE:

The staging is quite deep and with good height. But I felt like it could use a bit more width - but overall very enjoyable upfront experience. Tracks like: “The Secret Drawer – Bela Fleck and the Flecktones” or “She Don’t know – Melody Gardot” or “Bohemian Rhapsody (live aid) – Queen” sound amazing & enjoyable.

Imaging & Separation:


The Imaging on the is good for the price range. Tracks like: “Rotterdam (Or Anywhere) - The Beautiful South “or “Hello Again - Howard Carpendale & The Royal Philharmonic Orchestra” just shine through. Separation is quite outstanding for the price.



Comparisons:

No review is complete without comparisons. So here we are - with the BQEYZ TOPAZ vs Tinhifi P1 Max as they belong to similar price category, though the architecture is very different.

BQEYZ TOPAZ vs TINHIFI P1 MAX:



Build & Comfort: Both IEMS score great in this category as they are both very comfortable.

Bass: The bass on the TOPAZ is much more detailed and overall more refined.

Mids: The P1 MAX scores in the midrange having a more detailed and fuller midrange performance.

Treble: Both IEMs seem to have similar laid back treble but the TOPAZ seemed a tad bit more energetic.

Soundstage & Separation: Staging I felt was better ini the P1 Max while the TOPAZ had better separation.




Conclusion:

The BQEYZ TOPAZ to me seems a a very commendable IEM for the price specially for people who love up close sound with a bit of warmth. It's a good IEm and plays well with most DAC/AMPs and players I have tried with - hence becomes an easy recommendation from my side.

Every day the under 100$ price segment is getting tougher and tougher with new releases. Back in the day, I remember Moondrop Aria grabbing the position of top performer for several months, but then the segment got crowded with different sets such as FiiO FD3, DUNU Titan S, etc. The segment is actually quite popular as most new audiophiles start with this price segment only. They actually want to experience how audiophile-grade products sound before they could decide to play in the big leagues or maybe just stick themselves in this particular segment to explore different tastes. Most Brands also understand this and they regularly update this segment with new and updated products. BQEYZ, the brand mainly known for Spring, Summer, and Autumn(well they actually named their products on different seasons), has released a new hybrid set in this highly competitive segment, the BQEYZ Topaz. With a dynamic and a piezoelectric on each side, the Topaz brings a different take on hybrid configurations in the market. Actually, the brand has good experience in implementing piezo drivers in IEMs(Spring and Summer series had them). Let’s check out what the latest BQEYZ Topaz has to offer in this highly competitive price segment of under 100$.

A short disclaimer:-

I was provided with the review sample of BQEYZ Topaz by Miss Elle Zhou from the brand. The unit doesn't have to go back unless asked for, rest assured all the thoughts and impressions in this blog are completely my own based on my own experience with the set over the past few days.

The unit has been burned in for about 100 hours before critical listening for this review. I would like to thank Ms. Elle Zhou for the sample, you can check out more details on their product page here. You can also read my review on Gizaudio website over here.

Unboxing the BQEYZ Topaz:-

Won’t bore you guys a lot with the unboxing details. The pair comes in a simple cardboard box with a colorful top cover. It looks simple and elegant. Inside we have the IEMs sitting in a foam cutout with ear tips right underneath it. There’s also a silver zipper carry case in a round shape. The stock cable is inside this carry case. We also have a warranty card and a user guide in the package.

Package Contents:-

>Pair itself.

>Stock cable with 3.5mm termination.

>Six pairs of silicone ear tips.

Design and Build Quality:-

Topaz has got resin shells with metallic face covers and a golden-colored metallic ear nozzle. Face covers have a mellow purple-colored finish with BQEYZ printed on the right side and Topaz printed on the left side. The shells have a total of four vents, one at the face cover and three on the internal side of their cavity. Shells are lightweight and provide a comfortable fit. I would say the pair looks quite elegant and fits perfectly.

Fit & Isolation:-

As I mentioned just above, the Fit with the TOPAZ is super comfy. No issues as such. But isolation is pretty average. None of the stock tips were able to give me good isolation, so I explored my collection of ear tips and found the set to give the best isolation with Moondrop Spring Tips. Still, the isolation is average.

Sources I have Given To The TOPAZ:-

I have used the BQEYZ Topaz with a variety of sources ranging from a smartphone to portable DAC/AMP and portable digital audio players. I find the pair not to be very demanding but it surely shines with a decent source. Phones might drive the set adequately, but to explore its full potential, I recommend using it with a dedicated portable DAC/AMP or a portable Music Player. Sources I have given the set would include Redmi Note 10 Pro smartphone, Questyle M15 portable DAC/AMP, and Shanling M7 DAP.

Sound Impressions:-

Having heard the likes of Aria, Titan S, I was fully prepared to take on the latest Topaz from BQEYZ. Previously I have also heard other products from BQEYZ like the Autumn(which I actually liked), Summer(which was also good), and Spring 1(good but a little peaky), I was kind of expecting a Summer or Spring-like sound from the Topaz over here. I would say, the Topaz lives up to that expectation but with a slight change. You no longer have that tingy treble from Piezo that Spring 1 and Summer series had. It’s much more controlled now and I would say the Topaz sounds smooth, and inoffensive throughout the frequency band. BQEYZ has adjusted the tuning of the Topaz for a smooth U-shaped profile with a warm tonality. The pair has got a good punch in the lower end, it sounds meatier and lusher than Aria for sure. Midrange holds good clarity and is a little recessed in the lower mids region. Upper mids take a step ahead and bring the vocals a little forward giving an impression of a W-shape in some vocal-centric tracks(But it is U-shaped). Treble region, as I mentioned earlier, has got a smooth and inoffensive presentation. I won’t say it extends as much as the Spring series but it surely isn’t as brittle as the Spring series. Stage-wise I would say the presentation is good enough for the price. Topaz has got good width and depth. Layering and separation of instruments could be a little better(Aria does a little better job here I would say).

I would say BQEYZ Topaz has a charming, relaxing sound tuning. It complements genres such as Pop, Vocal-Centric, and regional Bollywood with its solid lower end and clean midrange. It’s good for Rock music too with its smooth treble but could be better with a little more extension I would say. Transients could be faster though. Now, let’s move forward to discuss different frequencies.

Lower-End/Bass:

Punchy, Lush, and hard, are some of the words that come into my mind after listening to the Topaz. The pair is tuned nicely with a kicking lower end. It feels like the mid-bass has got more emphasis over here that overshadows the sub-bass shelf a little. I won’t say it’s emphasized to the extent that it bleeds into the mid-range but I would say it surely overpowers the sub-bass response. Don’t get me wrong over here please, you will hear a decent rumble in the sub-bass region too, it just needs more presence IMO. Drum kicks have got more authority with the Topaz. Bass response is overall fun to listen to. It adds a sense of warmth and lushness throughout the frequency band. I would say Topaz has a better body in the lower end than the famous Aria, but Aria sounds faster to my ears.

Midrange:

Topaz presents a clean and lovely midrange. Lower-mids are a little recessed but the upper mids come forward nicely giving the set a smooth U-shaped profile. Vocals, both male and female have good authority and sound phenomenal. They have good clarity, sound a little warmer than neutral, and hold the listener with a charming presentation. Last night, while taking the notes for the review, I was listening to the track “Speak Softly Love” by Yao Si Ting, man Topaz was conveying the emotions so nicely. Just lovely I would say. In terms of vocals and the overall midrange, I find Topaz to have a better presentation than Aria.

Treble:

BQEYZ has got good experience with Piezo drivers now. They have implemented them nicely in the Spring and Summer Series. But this is by far their smoothest implementation in the Treble region. The pair holds good energy but presents it in a smooth manner. I guess this has been done by cutting down on some of the extensions in this region. Topaz shows good clarity and maintains the tone for Electric guitars, Violins, and Pianos in the high notes. There’s a little sibilance too but that’s negligible in quantity and hardly comes to notice. I could enjoy the Topaz for longer hours without feeling any fatigue or tiredness.

Soundstage:

Topaz has got good width and depth for the soundstage. Air and separation are decent, I don’t notice any congestion between the instruments. They sound nicely separated and can be identified separately, but I won’t say the pair is spacious or airy. For me, Aria would be airier but then it lacks the body hehe, you win some, you lose some .

A Short Comparison: Moondrop Aria vs BQEYZ Topaz!!

I had the pleasure to own the Moondrop Aria a few months back so I would like to share my thoughts on between the Aria and the Topaz too. Both are priced the same at 79$, but they both differ greatly in their sound performance. (Please note that these impressions are based on my memories of Aria, I don’t have it in hand to compare them right now).

>Aria has a more neutral sound presentation, Topaz sounds warmer.

>Topaz shows a better body throughout the frequency range. Aria sounds a little lean and thin in comparison.

>Soundstage width used to be better on the Aria, Topaz definitely has better depths on the stage.

>Aria reaches deeper with its sub-bass, and Topaz shows more strength in its mid-bass.

>Vocals have a warm tone on Topaz, but they show better authority in the output.

Final Words For BQEYZ TOPAZ:-

TOPAZ has become an instant favorite of mine. It comes at a highly competitive price but it leaves a mark with its performance. Yeah, the pair has a few issues of its own like average isolation, and an emphasized mid-bass region, but when I put the TOPAZ into my ears, I just get a mesmerizing listening experience. IMO its plus points surely outperform the few cons that I have mentioned throughout the review. Simply enjoyed my time with the set .

Hope you guys like my writeup, please leave me a like if you do

INTRODUCTION:
BQEYZ (Best Quality Earphones For You), the brand based out of China is a well known brand among the Audiophiles does have some great collections of IEM in their catalogue. They don’t launch the products frequently but if they do launch they execute in a perfect fashion. The Spring, Summer and Autumn being their flagship models, Topaz is their latest mid range offering adopting a hybrid driver mechanism combining a DD and a Piezoelectric Driver.



SPECIFICATIONS:
Driver configuration:13mm dynamic driver 9 layers of piezoelectric ceramic driver
Impedance: 32ohm
Sensitivity: 108dB
Frequency range: 5-40KHz
Cable length: 1.2m
Plug type: 3.5mm/2.5mm/4.4mm
DISCLAIMER:
This unit has been provided to me by BQEYZ Audio at a deal price in exchange for my honest opinion towards the product. The whole views are based on my observations and pairings with it hence it might differ from person to person.

DESIGN AND FIT:
The design of the Topaz is pretty usual in ear type enclosed partly metal and partly resin. The faceplate adopts the metal which has a subtle branding over it. The resin part has fins that fit snugly in the ears. The 2 pin slot is nicely tucked inside the resin body and the overall finish does feel sturdy.
The provided stock cable is pretty good in terms of feel and texture. It has a nice supple nature to it and the braiding is done in a proper fashion. The provided stock tips are nothing special and do provide a decent seal. The fit however is on the verge of not being perfect and it does affect the seal and isolation. The vent on the faceplate does affect the isolation but still it could have been better.


SOUND:
The sound profile of the Topaz is more on the U shaped side with more emphasis over the bass. The bass here is thicker and full bodied while the mid range is kept at a neutral presence with lush presentation and the treble is tuned to be smoother and tamed which is unusual for a Piezo driver yet they deliver some impressive micro details. The technical aspects are not the strongest aspects in this IEM which we will discuss in the following sections.

BASS:

Positives:
The bass in the Topaz is well textured with equal emphasis over the sub and the mid bass section. The sub bass does dig deeper with enough reach thus providing adequate rumble. The mid bass quantity is on the right side with adequate fullness this gives a nice body to the overall presentation. The sub and the mid bass section can be distinguished clearly and has a nice sense of demarcation between them. Haven’t noticed that much of mid bass bleeds, it’s there slightly but does a good job in providing the mid range a very lush experience.

Negatives:
Though the bass is on the right quantity with great texture, fullness and sub bass reach the quality however is on the middling side. The speed is on the verge of being too slow thus the separation gets the hit. They are not that noticeable but can be observed in some complex tracks. The mid bass body is good but lacks the slam thus making them powerless at times.

MID RANGE:

Positives:
The Mid Range in the Topaz is sided over the neutral aspect with one of the best tonality and timbre in this price range even after having the Piezo drivers in it which is a rare thing to master. The presentation is just on the precise staging where it's neither too laid back nor too forward. The vocals are slightly placed forward compared to the instruments.

The lower mid section carries that nice fullness from the mid bass section thus delivering some impressive notes. Each note carries a nice body and weight making the whole lower mid bass section fuller and pleasing. The male vocals are beautiful to listen to since it has that natural tone and fullness. The Upper mid section is neatly elevated a bit to give that sparkle and life to the percussion instruments. It also gave the female vocals a nice presentation making the listen more engaging. The Piano notes and the guitar strings got that natural tone making them appear more lively. The micro details in the mid section are captured out neatly without any sort of issues.

Negatives:
The negatives are much less in the Topaz but here's anyways, the transient response however felt not that great in the Topaz where the notes edges are pretty smoothened out hence they don’t have that but in each notes decay. The notes tend to be softer and calm rather than giving that aggressive and engaging bite in the end. The separation as I stated in the bass section here too feels slightly off but that can be only observed in some specific cases of complex tracks.


TREBLE:

Positives:
The treble in the Topaz is tuned pretty nicely where this is the first IEM that I heard without any fatiguing high notes even with a Piezo driver in it. The Piezo in this IEM is tuned meticulously, making them deliver impressive treble notes that are pretty pleasing to the ears. The extension in the top end is pretty nice with linear elevation. No sort of harsh spikes or uneven notes are observed. The detail retrieval is moderate with a nice sense of air and space.
The timbre of the instruments appears pretty natural despite the use of the Piezo in this. The cymbal crashes and the trumpets do sound neat and bright enough. The attack and decay of the percussion instruments appears to be precise in terms of timing. They do deliver some enough shimmer and brilliance in the top end.

Negatives:
The negatives are such as when it comes to detail retrieval the Topaz is not the best. It's neither too bad nor too good, rather they are average for the price. Since the treble is made to sound more smoother and pleasing the extension is kept limited hence the detail retrieval is not a strong aspect of this IEM.

TECHNICALITIES:

STAGING: The staging is intermediate between being too wide and too narrow. Adequate space is present in between the notes thus representing a grand enough presentation. However the height seems to be moderate in space but shows some good depth sensation, thanks to the proper bass response.

TRANSIENT RESPONSE AND LAYERING: These are not the best aspects of the Topaz. The transient response and the layering feels fuzzier where the note edges are dampened and smoothened out rather than providing a crisp bite.


IMAGING: They feel pretty good with nice 3d positioning of the instruments but still shows its blurriness when the complex tracks are played out.

Detail retrieval, as I stated in the above sections, feels moderate at best and can be improved in the next iteration.

VERDICT:
Topaz, the latest offering from the house of BQEYZ ( Best Quality Earphone For You ) is a well executed package that delivers an impressive sound as well as a great build at an attractive price. The Topaz is equipped with a hybrid driver mechanism where it has a 13mm Coaxial Dual Cavity Dynamic Driver + 9 layers Piezoelectric Driver both nicely feels coherent with each other making the sound to appear more linear and organic. The bass in the topaz feels now more authoritative compared to the previous versions with more sub bass presence to make you feel the subtle rumbles. The mid range is pretty lush with melodious presentation providing equal weight to each note. The treble is tuned smoother and does deliver a unique treble output compared to the other Piezo IEM’s without causing any usual Piezo after sensation.

It does have some quirks in the sound where those technical aspects (especially the transient response and the layering) are not the best and needs some improvements which will certainly be rectified in the next iteration of Topaz. The negatives can be easily compensated by the natural tonality and the neutral timbre despite the Piezoelectric driver in this Topaz. The build is top notch since they are partly metal and partly resin. The faceplate is made of metal giving the IEM a premium look and feel while the medical grade resin provides nice comfort and isolation to the ears, however the isolation could have been better.

Overall, the TOPAZ is a well tuned IEM that goes well with any sort of genre and does provide you that relaxing and smoother overall listen. This is indeed a SMOOTH SLAYER in this price range and can be an easy buy for anyone and should be in everyone’s collection.

SPECIFICATIONS

• Driver configuration: 13 mm LCP (liquid crystal polymer) diaphragm co-axial dynamic driver with 9 layer piezoelectric driver
• Frequency response: 5 Hz – 40000 Hz
• Impedance: 32 Ohms
• Sensitivity: 108 dB (no units provided)
• Cable: 2 pin, 0.78 mm 4 strands silver-plated cable
• Tested at $89 USD

ACCESSORIES

Other than the IEM, these are included:

- Cable
- 6 pairs of eartips - 3 pairs are "reference" tips, the other 3 are "atmosphere" tips
- Cleaning brush
- Carrying case



The accessories are more than decent, I've seen some competitor IEMs with way less goodies. The cleaning brush and clam-shell semi-rigid case are a very nice addition.

The "reference" (grey) tips are shorter with a wider bore. They give a more balanced sound signature as per the "reference" moniker, with a more neutral sound-scape and more expansive soundstage. The "atmosphere" (black) tips are taller with a narrower bore, they increase the bass, though at the expense of a more compressed soundstage.



During ordering, one can select an unbalanced (3.5 mm) or balanced (2.5 mm or 4.4 mm) cable, depending on your preferred source pairing. The stock cable is very supple and well braided, with minimal microphonics. The cable is definitely very usable and I don't think there's a need to source for aftermarket accessories with the goodies provided in the packaging.

I much appreciated that the Topaz cable features a 2 pin connector, I've had my fair share of mishaps with MMCX connectors in budget sets, especially with frequent cable rolling.

The rest of this review was done with the stock "reference" eartips and stock cable, with no aftermarket accessories used, so as not to add any confounders to the sound.


BUILD/COMFORT

The Topaz is tear-drop shaped, and the design is pretty elegant. The housing is fashioned via a 5-axis anodized aluminum, and there's a violet or grey variant you can select during ordering.

Build is of very high quality, and the earpieces are light, yet comfortable. I've no issues from a comfort perspective, I've used the Topaz for hour long testing sessions without issues.

I didn’t find any driver flex during usage, YMMV once more, as this is dependent on ear anatomy and type of tips used.


ISOLATION

Unfortunately, isolation is sub-par on the Topaz, due to a vented design for the dynamic drivers. It is still usable outdoors though, but don't be expecting unvented pure BA type isolation levels.


DRIVABILITY

I tested the Topaz with:
- Khadas Tone Board -> Schiit Asgard 3 amp
- Khadas Tone Board -> Topping L30 amp
- Sony Walkman NW A-55 DAP (Walkman One WM1Z Plus v2 Mod)
- Sony Walkman NW A-55 DAP (Walkman One Neutral Mod)
- Questyle M15 DAC/AMP dongle
- E1DA DAC/AMP dongle
- Colorfly CDA M1 DAC/AMP dongle
- Tempotec Sonata HD Pro dongle (BHD firmware)
- Smartphone

The Topaz can be driven from weak sources, but definitely scales with juice.


SOUND & TECHNICALITIES

The Topaz sports a very refined U-shaped tuning, it is pretty all-rounded for most music genres. Even though it utilizes a very unique DD + piezo config, I'm glad to report that the Topaz is one of the most tamed piezo sets I've had the privilege to use, with great coherency on display.

Most piezos suffer from a treble zing with a brittle and artificial treble, perhaps due to the very fast transients the piezos bring to the table, but the Topaz is pretty dampened in the treble, with quite a natural timbre for a piezo containing set. Most other piezo IEMs have flaws in timbral accuracy, which is not the case with the Topaz.


Graph of the Topaz via IEC711 compliant coupler. The 8 kHz area is a coupler artefact peak.

The bass is mostly sub-bass focused, though it is not the most extended in the sub-bass. The bass is just slightly north of neutral and the Topaz isn't a basshead set.

In terms of quality, bass speed is on the slower side, with some mid-bass bleed. This may obscure bass texturing and causes some smearing during fast/complex bass tracks, but on the flip side, it adds warmth and lushness to the lower frequencies, which gives the Topaz its characteristic analoguish tonality.

The lower mids are warmed by the aforementioned mid-bass bleed, giving great lushness to this area. Transparency does suffer a tinge as such - there's an added veil - but the thick note weight and big bass give a very analogue sounding feel. The upper mids are forward but far from shouty or fatiguing.

The lower treble continues on from the minor boost in the upper midrange, but the treble borders on dark and actually tapers off pretty quickly. This set is thus very safe for treble sensitive folk - sibilance is mild - but there's loss of clarity and micro-details, so trebleheads might find this area wanting. Air and sparkle are hence lacking.

In technical aspects, the Topaz won't uproot any trees. Instrument separation and imaging are bang average. The "reference" tips open the soundstage more than the "atmosphere" tips, but even with the "reference" tips, soundstage width, depth and height are about average.

As per the previously mentioned veiled sound signature, micro-details are not the strongest suit on the Topaz. For a piezo containing IEM, the note edges are actually blunted and not as quick in the transients as some other piezo containing IEMs.

TLDR: the Topaz is very non-fatiguing and smooth, and is a great set to chill to. It is not an analytical set for critical listening, as the Topaz goes for timbre and tonality over outright sheer technicalities.




COMPARISONS

TRN VX Pro

The VX Pro is more V-shaped than the Topaz. The VX Pro has bigger bass and more treble extension than the Topaz. However, the VX Pro is much more shoutier and fatiguing, with sibilance in spades.

Timbre is worse on the VX Pro, though technicalities like imaging, micro-details and soundstage are better on the VX Pro. The VX Pro has tonal flaws, with incoherency present - the DD bass is slower than the BAs handling the mids and treble, and music sounds disjointed as such. The 8 kHz area on the VX Pro is very hot with this adding sibilance as previously mentioned.

There is also marked driver flex on the VX Pro, which is not present on the Topaz; this may be a deal-breaker for some.

In conclusion, the VX Pro may be more technical, but in other departments, eg coherency, timbral accuracy and tonal balance and driver flex, the Topaz is way more refined. I'd recommend the Topaz over the VX Pro if you ain't a technical detail freak.


TRI Starsea

The Starsea has 4 potential tuning configurations due to tuning switches, so it can be anything from neutral to a mild V-shaped profile. As such, the Starsea is more versatile in tuning.

In terms of technicalities, the Starsea is a league ahead, with better imaging, instrument separation, clarity, micro-detailing and soundstage. The Starsea has better isolation too and is more airy with greater treble extension.

Across all switch settings, note weight is thinner on the Starsea; it sounds more analytical than the analoguish sounding Topaz. The Starsea has BA timbre present, with the timbral accuracy not as organic as on the Topaz.


CONCLUSIONS

The BQEYZ Topaz is a smooth and non-fatiguing U-shaped set, that is well suited for chilling and to relax to. There's no shoutiness or fatigue on display, and timbre is quite organic compared to other piezo brethren. Accessories are generous, the Topaz is relatively easy to drive and comfort and build are top-notch.



While not the most technical IEM, the Topaz has a very lush midrange and treble sensitive folk will be quite at home with the tuning. The tuning is really atypical for a piezo containing IEM, and there isn't the piezo zing associated with other IEMs that have the piezo namesake.

Personally, I go for tonality and timbre over outright technicalities, and the Topaz definitely aces the former areas. I do think it will be a keeper for me, it will be a pair to just enjoy music for what it is!

Intro
BQEYZ is a company that most in the ChiFi community is/should be familiar with.Their previous “seasonal” IEM,namely Spring,Summer,and Autumn,two which i have reviewed both the Summer and Autumn and had very good experience with it.What i like about BQEYZ is that they take their time to really fine tune their release and make sure that when it is ready to market,it will be a hit rather than miss.The same applies to the Topaz which i have here with me,to my ears and mind you,your experience may vary of course due to everyone’s ear perceive/hear differently,i do find them sounding a little like Summer,but without the Piezo’s zinggy sensation.You can find out about the packaging and build from other reviewers as i am going to be focusing on the sound mainly.

I do have to mention about the fit,as with the other two BQEYZ IEM that i reviewed,i do have some problems with their stock eartips being not being able to form a proper seal,so i had to use 3rd party eartips which is Audiosense’s S400 eartips which fits and seal well for me.

Sound
I would start off by saying Topaz’s sound signature is warm and a slightly smoothed top end despite sporting a piezo driver,quite neutral to my ears.This is not exactly a bad thing as I had reviewed BQEYZ Summer previously and the piezo in it is kinda splashy and a little harsh.After having a conversation with Elle from BQEY,i was told that the piezo in Topaz has been tuned differently hence resulting in what is heard in Topaz.

Bass

• Topaz’s bass is not dominant and it is rather linear from sub bass to mid bass transition
• Bass quantity is just right and it is the quality bass rather than quantity
• Good amount of punch from the mid bass
• Sub bass is present but not overshadowing the mid bass,it does its job when its called for,but the rumble is nowhere near bassheads preference,just the right dose for the fun factor
• Bass has good texture in general due to the warmness and i would categorise them as audiophile’s bass response as it has a rather neutral bass response and not emphasised

Mids

• Topaz’s mid to me sounds organic and very well textured
• I find the warmth is just nice and vocal for both male and female has got very good texture and they don’t sound thin at all,they sound sweet and lush
• Stringed instruments doesn’t sound that forward,but it does benefit from the added warmth with ample of body to it,not too bad overall
• Male vocal that has a deeper tone benefit much from the added warmth and it is very pleasant to listen to

Treble

• I expected the treble on Topaz to be a little zingy as it sports a piezo,the reason why i had this expectation is due to the past experience with BQEYZ’s Summer,dont get me wrong,Summer is good,it’s just that the high can be a little zingy at times
• I guess BQEYZ took in the feedback and tuned the piezo to be different this time,the highs are good and it doesn’t have that zingy feel from the piezo despite sporting a piezo
• The treble this time is smooth and a little laid back,while retaining the air and extension
• Detail retrieval is alright but don’t expect it to be analytical as Topaz is definitely not an analytical set,it is a little smoothed out but not too bad overall
• A good implementation on the treble overall

Soundstage/Imaging

• Soundstage is good and the overall presentation of the soundstage sounds wide and has a good depth and height which would be perceived as sounding “big and good immersion
• Imaging is good as the instruments can be pinpointed easily,however it does struggle a little during busy track such as Slipknot’s Duality,but considering it’s price point,it is actually pretty good

Comparison (BQEYZ’s Summer)

• I don’t have Summer with me anymore,so my comparison is purely based on my memory and my time spent with Summer.Do take this into consideration when reading on the comparison section
• Unlike Topaz,Summer sports an extra BA hence making it a Tribrid?In terms of tuning,i would say they’re quite different
• Summer is energetic and compared to Topaz,Topaz is laid back and easier to listen to,making it suitable for long sessions
• Treble is a little zingy on the summer due to the piezo,both topaz and summer having good extension and air and sparkle,just that Summer’s presentation might come off as a little harsh to some who are treble sensitive
• Topaz has got more note weight on the lower end of spectrum,sub bass rumble and also more thumpy on the mid bass,Summer is not too far off but the sub bass does sound a little rolled off based on my memory and not as thumpy as Topaz
• In terms of soundstage and imaging capability of Summer,they perform more or less similar as Topaz based on my memory
• Vocal on Summer does sound a little thinner

Final Thoughts
BQEYZ definitely did a good job for the Topaz as they managed to fine tune the Piezo to sound a little less zingy while still retaining the extension,air and sparkle,Topaz is not the IEM that will WOW you when you first put it on,instead it is the one that grows on you as you use them,at least i feel that way,also,if you like something that’s analytical,then this is not for you,you may look for alternatives.Topaz to my ears is more musical sounding rather than analytical.

*BQEYZ Topaz was sent to me FOC and I only have to pay for the shipping fee in exchange for this review from Ms Elle.I appreciate the opportunity given,however,all thoughts are of my own and I am not under any influence nor do I receive any compensation for this review.

The Review Of The BQEYZ Topaz​

Introduction​

BQEYZ is a known chi-fi brand for releases like spring 2 , Autumn, KC2, etc. Especially known for their piezoelectric driver configuration And Today I’ll be reviewing their newly released BQEYZ Topaz.

Disclaimer​

*Thanks to BQEYZ for sending this unit for review. As mentioned in all of my reviews, same goes with this one too and that is, each and every thoughts below mentioned are my personal own thoughts and they are not fiddled with any outside influences.
*I will be referring these IEMs to as 'Topaz' for the rest of the review.
*And at last I will only be reviewing the Topaz on the basis of their performance, I do not care what these are made of or packaged with when newly purchased unless it affects the sound in any sense what so ever.

Specification​

The Topaz has a 2nd Gen 9-layers Piezoelectric Ceramic Driver and 13mm Liquid Crystal Polymer Diaphragm each side, this IEM uses coaxial DD with piezoelectric patented technology. The impedance is 32ohm and sensitivity is 108dB. The frequency range is from 5hz to 40KHz

Sound​

Okay, so the Topaz has a balanced sound while it rather sounds more V-shape with a lot of energy in the bass and a lot of energy in the treble region. While bass is really nice with tuning, the mid range sub dues in the mix and sounds mellow which is alright as they sound non offensive but the treble back again sounds very up front and energetic. Therefore I mentioned this IEM as V-Shape than a balanced sounding one.

Treble​

The treble region is very energetic and upfront. The upper treble sounds a little weird with some sibilance with cymbal crashes, female vocals and electric guitars. While the lower treble sounds somewhat incomplete with presentation, though everything sounds good with details and range is quite extended still leaves with a feeling wanting more.

Mid Range​

Coming to the mid range, the upper mid range is present in the mix, even sound forward. Every instrument placed here is more close and warm sounding. The lower mid range are the same with thick and warm response. The vocals feels drowning in this region and aren’t so clean with presentation. Over all presentation is average for an IEM. This is not something I would’ve not expected. Is still believe the response is better than more IEMs that comes in this segment or in a more expensive one. But one thing is sure the vocals are melodious to listen to and sounds very welcoming.

Bass​

The bass is really as an overall presentation is okay. The mid bass and sub bass shelf seems to be at same boosted dB level. Though I still believe there is more emphasis on the mid bass. And yes the mid bass really leaks into the lower mid range which is more than they should be. The bass is more slamming than rumbling, it is more thumpy than punchy. Although the bass is fast and hits hard. Moreover the bass gives a false sense of being organic and natural. though the bass slam still feels light and not that deep. The sub bass extension is just okay.

Technical Performance​

The technical aspect of these IEMs aren’t surprising as normally founded this presentation in average sounding IEMs, though the speed is really great.

Soundstage, Sound Imaging & Separation​

The sound wide and depth is just okay, the stage is really not that open and sounds intimate or close sounding. the 3d holographic image is not that clear and spacious to distinct, most of the sound elements sounds clashed together or just blunt. The imaging is rough and not proper. The separation is not quite what it should be. For the price I believe titan s is a safer choice. But due to differences made this is more tonally better.

Speed & Resolution​

The resolution and detail retrieval is not quite that amazing. Though the speed is really nice, fast and tight. The note attacks are precise and clean though the decay is a bit resolving and late responding. Though this response is really better than any other IEMs I have listened to.

Conclusion​

To conclude this review of the Topaz, yes this have flaws and yes this sounds very generic but the treble and bass will surprise you. This is really fun to listen to and exciting too. Well if compared with Dunu Titan S and Moondrop Aria, if I wanted good bass head IEM for the price none of the mentioned above will suffice but Topaz. I will definitely recommend to those who neither liked Aria nor Titan S or maybe found something missing in both, to give this one a try.

INTRODUCTION:


BQEYZ will always be a special brand/company to me. Their KC2 is what got me started in this hobby. Thanks to Eiji Romero.

After KC2, I bought the Autumn. A well-received gear and with a unique tuning execution, the magnets. Bqeyz is also known for releasing patented technology and they like to explore new tech on their products.

And we now have Topaz. If you want to hear my impressions and perspective, as a musician, pls do read on…

DISCLAIMER:

My opinions here are completely my own. I am NOT in any way influenced by any form of incentive. This is purely my honest, subjective impressions and experience with the gear on hand. I cannot stress more that you should take this as a grain of salt for we have different perception to sound and what we hear. I always try my best to stick with the stock accessories that come with the gear by default. You are free to try other methods such as tip rolling or cable rolling. Below are worth noting before concluding on what I say here:

1. DAP (digital audio player, be it phone, laptop, mobile, or stationary setup)
2. DAC or dongle or any external amp
3. Ear Tips
4. Cables
5. Source of audio file be it offline FLACS or streaming services like Deezer, Apple music, Tidal, Qobuz, Spotify and the likes..
6. Your playlist. It matters and is worth to be considered when reading from a reviewer's perspective. It is apparent that you get to know your favorite reviewer and what they are listening to leisurely and critically.

My reviews are more on how music sounds in my ears. The technical stuff like frequency graphs and the physics behind the tech and drivers used, I leave to other reviewers.



SPECIFICATIONS:

Configuration: 1 x coaxial dual cavity dynamic driver with 9 layers Piezoelectric
Impedance: 32ohms
Sensitivity: 108db
Freq response: 5-40khz

PACKAGING:

The box is medium size. Neatly presented. Colored in light blue or purple and white. Bqeyz always gives this minimalist style of design that is very pleasing to the eyes. This is my 3rd product from them and the way they design their packaging somewhat became a pattern. Below are the inclusions:

1. One set of Topaz
2. 1 cable. Very nice and thick. Silvery white in color
3. Some documents. Warranty and guide
4. A cleaning tool
5. Three pairs bass tips, three pairs wide bore tips likely vocals or balance tips

For the entirety of this review, I used a balanced 2.5mm termination, and L size wide bore tips. Main source is offline hi-res files on my Hidizs Ap80 pro.

Now let us dive into how Topaz sounds..

LOWS:

The lows have a lean and mature character. More importantly, lows have that round sound. It has that thump and punch, but the roundness is prominent. It has good reach in the sub area. Mid bass has a nice presentation that I personally prefer over the sub. The lows doesn't linger long, and have good decay. This results in minimal bleeds to other frequencies. The attack though, is somewhat laid back. Resulting in a less punchy lows presentation. As I am accustomed to fast drivers, and to be honest a BA guy, I was first let down by this nature. But as 4 days passed, the lows are still very very commendable. Bass oriented tracks will still give you good rumbling. Busy tracks struggle a bit in the lows department but I am being nitpicky here.

Conclusively, what I loved about the lows here is its lean and mature nature. And its round character. My only caveat here is the speed and attack. To my liking, the lows lack that aggressiveness that I personally prefer.

MIDS:

The mids is Topaz' strength. Mids are lush, rich, weighty and have good body. Elements and instruments are very rich and desirable. Guitars both acoustic and electric, are very whole and weighty. Male vocals are favored but by just a small margin. Pianos, rhodes, organs, strings, orchestra all sounded very natural and organic. Female vocals are still very commendable but lack energy and air for my liking. To be honest, the mids reminded me of KC2. No recessed mids here. So expect a lot of elements to have a forward nature. Vocals are always presented with a forward nature and smooth flow. It is worthy to claim that Topaz' key strength is its vocal presentation.

Conclusively, mids here pleased me greatly. As a mid centric that I am, Topaz is for those who like their elements to be heard. Lushful and rich. If there is something I am going to nitpick, it is that the mids lack texture. Actually this is a characteristic of the whole sound that Topaz lacks. Moving on…

TREBLES:

Ok, this is a critical part. First off, treble sensitives, now is the time to rejoice!! This one is definitely for you!! Trebles are relaxed and laid back. For some reason I cannot call it veiled because it does not turn me off considering that somewhat, I am in between a sensitive and a treble head. The funny and weird thing here is, once I plug Topaz in my ears, the laid back nature is noticeable. But just after a few minutes, my brain or hearing will accept this sound positively. But one thing is constant, cymbal strikes. They are lacking. The grit and bite that I look for, is not here. But this is nothing to put me off completely. I tell you, the trebles here are tamed, yes, but the details are still audible. Air and openness could have been more, but I still cannot hate the trebles here. The Topaz put me in a jaded circumstance here to be honest. Its like purposely hanging me for more, but then later on realize, hey, I like it. I do hope you get what I am saying. Lol


FIT & ISOLATION

This department is Topaz' weakness. As my third product from Bqeyz, the fitting has become a norm at some point. Shallow. Don't get me wrong. The fitting is nowhere near to be despised. But if you prefer a deeper fit, you might need some time to adjust here. Still the fit is pleasing for me. A benefit from this is, say goodbye to ear pressure. Isolation is average. This is very subjective and actually, it is quite good too if you hear some outside noise, especially if you are on the streets. So that you are aware of your surroundings. When I used M sized tips, the isolation was just horrible. My peers from our review circle suggested I switch to L size and that solved everything. The sound, seal, fit and isolation. If the stock tips don't fit you, I hope you are into tip rolling somehow.

TECHNICALITIES:

The tricky part. After a good 4 days of continuous listening with Topaz, these are my impressions on technicalities.

To start off, Topaz is overall average on technicalities. A hit and miss here and there.

Staging is somewhat between intimate and wide. A good sense of headspace is there. Depending on the track of course but a good width and depth is readily available if the track will call for it. There is this one time of how good the depth is. I was listening to an instrumental track, and there was a part in the track where a passage of vocals shouted. It was so well placed, that I turned my head around as if as though someone was calling my attention. I ended up laughing to myself. Lol.

Separation and imaging is average here. Nothing to hate here but for its price point, it could be better. Imaging is somewhat a hit and miss on this one. A bit on the blurry side. Less accurate. Separation is still very decent. But this is the reason why I cannot claim the Topaz to be analytical.

Texture is another weakness here. Be noted I am nitpicking now. Most of the time, the texture of elements that I am used hearing, falls short by a small margin. Not enough to put me off but it is noticeable. It is negligible.

One more weakness is speed. This is a laid back set folks. Manage your expectations. I prefer speedy drivers, but to be honest, the speed of the drivers here, is still adequate even though it is on the slow side. It is all about mind set. Lol.

COMPARISONS:

This is gonna be exciting. Again I don't do comparisons much. But I am trying to incorporate this to my reviews and make it a habit.

Tonality will be assessed in both quality and quantity. Technicalities will be simpler. We will use the > and < approach. Pls do note, this part is very subjective. This is based on my own preference.

Again these comparisons are all based on my personal preference. If you have these sets, your mileage will most likely vary.

PAIRING:

I will recommend a neutral or bright source for Topaz. My Hidizs Ap80 compliments Topaz, being Ap80 a neutral source. A neutral source will somehow help the tamed trebles. A warm source will make Topaz too veiled like with my LG V30.

SOURCES AND GEARS:

• LG V30 hifi dac (high impedance mode)
• Hiby Music player
• UAPP app (USB Audio Player Pro)
• Tidal Masters subscription
• offline FLACS
• Hidizs AP80 pro
• Deezer Hifi subscription

And many more… I always listen to High resolution format, being the least quality 16bit/44khz FLACS be it offline or online.

VERDICT:

This is yet another particular release from Bqeyz. An IEM good in its own right. Standing on its own character. There are some flaws here, especially on the technical side, but very very minimal. The scenario here is Topaz manages to please me not on the initial listen, but as we bond along with my songs. Which is very very charming and mysterious in a way.

So who is Topaz for?

• Treble sensitives. Rejoice. Given the tamed trebles, details are still there.
• Treble heads, forget it. Pass.
• Bass heads, you might appreciate this. The roundness and reach down low is commendable. Not brain-wrecking level though.
• Neutral heads and mature listeners
• Those who are looking for a relaxing set

A warm sound signature is not my preference anymore. Well at least not on the top of my list, but the Topaz is a worthy set to be considered for this sound character. There are ways to make that treble shine more, but I love it just the way it is. Technical side is on the lighter side of things but nothing to be despised or hated here. This is definitely a keeper for me and for its price point, and if you have reached this point and quite agree with my impressions and have a similar setup, by all means, pull the trigger on this one.

My most personal comment on Topaz is that it always takes me into a mysterious journey. At first listen, I am not blown away. This is every time I plug them in my ears. But after a few songs, it will begin to give me a particular sense of satisfaction. It's almost like it is alive continuously and consistently trying to brainwash me with its charisma. And this feeling alone is mesmerizing and bizarre. It surprises me and keeps me on my toes. And the result is a strange and peculiar audio nirvana.

Again, our hearing differs. Not one has the same hearing. Just like a fingerprint. So please take this as a grain of salt. Your mileage may and always most likely vary. Cheers and catch you on the next one!!

BQEYZ TOPAZ
Piezoelectric Ceramic Driver & 13mm LCP Diaphragm Dynamic Driver Hybrid In Ear Monitor

• 2nd Gen 9-layers Piezoelectric Ceramic Driver
• 13mm Liquid Crystal Polymer Diaphragm
• Dual Cavity & Broad Soundstage
• 5-Axis Anodized Aluminum Faceplate, Resin Shell
• Detachable 4-Core OCC Silver-plated Cable

The disco inside your head previous BQEYZ BQ3


My history with BQEYZ is comprised of only two past IEMs. The BQEYZ BQ3, and Spring 2. Now in all fairness I can sum both IEMs up as only being great at two sub-genres of music. That’s right the BQ3 with it’s giant 2X Double Bass pumpers, only really good at EDM. My quote from July of 2019: The BQ3 3BA + 2DD $68.99

“Race cars and kitchen appliances are tools, they only perform one specific task but do it well. I’m sure the BQ3 was tuned specifically for Electronic Music. In this regard it’s a grand tool. There are more well rounded IEM performers out there, but with EDM, the BQ3 stands alone in it’s price.”



The Spring 2: One 13mm dynamic driver copper shaft 13mm speaker + nano 9 layer piezoelectric ceramic driver and 1BA. $169.00

The Spring 2:
This was the BQEYZ flagship. And just the fact that it did really good renditions of Judy Collins, Joni Mitchell and Neil Young saved it from a bad score. In fact, if you were listening to singer songwriter music all day, you would have hit the jack-pot as far as bang-for-the-buck. Just look at the attention to detail and build quality! The fact that it came with a very special cable and complete accessory kit didn’t hurt matters any. But if you must know, the coaxial DD of the driver was thwarted. Somehow BQEYZ found it presentable to attach the top portion of the DD with a Piezoelectric driver? While some had issues with the tone/timbre of the Piezoelectric, I actually found it offering a special treble quality during side-by-side tests. It’s just the bass section of this unit produced woolly and incomplete bass as well as bad bass timbre. Remember though singer songwriter stuff never really utilizes such low frequencies. So in learning of this new 2nd generation Piezo.......I was excited. But what about the bass driver, will they improve that too?

Today:
These new TOPAZ IEMs are nothing short of a watershed product for BQEYZ. Where other members have also concluded that this is the best BQEYZ tune……ever. Gone is the intense bass of the BQ3, that was nice but bestowed a singular EDM purpose to the IEM. Gone is the slightly shrill treble and lack of bass impact of the Spring 2. In fact the Topaz bass while impactful and satisfying, goes to round off this signature miles and miles better than the Spring 2. If you ever wanted to try an BQEYZ product, now is the time. Finally they have truly done well. I say this because my hopes for a well rounded performer took place. An IEM that not only sounds good from a range of sources, but does all music genres well. The build, cable and accessories provided seal the deal. The fit is amazing……….but of course, it’s all about the sound, right?



The Sound:

Sound generalizations:
Probably the most fun (for me) happens with these super low (frequency) sub-bass nuances. Such antics are the TOPAZ showing it does sub-bass competently. Due to the tune we are bestowed with everything……all of it. It’s so complete and well done, I can’t imagine anyone not liking it. Just enough character too, as this is a one-of-a-kind build methodology. A Piezoelectric stacked directly on-top of a 13mm LCP Diaphragm. This Dual-pole Dynamic means phase coherence and transients created top-level. Meaning it truly sounds original while doing a composite naturally accepted as correct. To be critical and compared to way more expensive IEMs, it doesn’t provide all the detail, instead a style of subtle grain, probably piezo-grain? Also the TOPAZ doesn’t provide a complex and sophisticated treble staging, typical at this price point. Still what the TOPAZ does do is nothing short of remarkable. Simply the pace, imaging and timbre is amazing at this price point.

To think what BQEYZ has become……in four short years?

Bass:
Pre-burn-in impressions had me hearing way more sub-bass only. After 100 hours we are blessed with a more well rounded bass presence. Though I hear more sub-bass than the graph would have you believe? Part of that could be the bass detail giving a feeling of an added amount (over and above) what's actually present? This once-in-a-while phenomenon occurs when bass is well defined. Also the rest of the tune is leaving the window open to visualize this bass. Besides the tune, much of this bass delineation occurs due to soundstage. It’s this beautiful placement in the soundstage, when we realize we are getting more than we bargained for.

Many may view this signature as having a darker slant, and it does, but there is a balance and a sophistication at hand well above the humble price point. The bass is present more due to the drop-off staring in the highs at 4K. The measurement after 4K shows an 8K peak, but I’m pretty sure it’s a measurement resonance. Such tricks often surprise you with a loss of intensity when hearing composite sounds; with orchestral blasts of composited bass and treble. Thus the end result will be less treble intensity (thus more bass). Another reviewer wrote of the Topaz as being a friend to the table sensitive, and I totally agree. This 13mm LCP dynamic drive is a whole new animal offering speed and detail never found being associated with BQEYZ. While there is an expansion of imaging out into the soundstage, there is still a lack of crystal-clear separation inside of the main display of music, normally found in more expensive IEMs. It is what it is. But the entertainment factor is there none the less, probably due to such big sound in general. This has to be the biggest difference that many IEMs have begun to offer as of recent years…….big sound….and the TOPAZ goes very much along with the pack in offering such a feature. If you study the graph you will note a generally perfect response curve. Such a subtle dip right before 1K, and the sexy slope behind goes beyond what I can put into words to describe just how inoffensive and pure the bass response is.

The only downside I found was the excessive bass/warmer Walkman WM1Z DAP which seemed to muddle the waters. The more midrange expanded Walkman WM1A impregnated the midrange with more dexterity and agileness. I liked that. The real downside seems to be a lack of upper bass cutting in the mix. Meaning the bass driver is great at many aspects of bass reproduction, but itemization/delineation of the upper-bass is defiantly not its strong point.



Midrange:
The Pinna gain region is never ever hot, or even close to hot. Peaking at 2.4K then traveling a smidge down to 3K, only to finally drop at 4K, the TOPAZ walks that line. A gorgeous line of really doing it all in a slightly subdued manner. While vocals are not presented like a vocal specialist IEM does, they are not really set back in any way. Any lack of detail may have something to do with Piezo-Grain, only allowing us to be so close to a vocal performance. So it’s not FR but a style of technicality with is keeping us at a slight distance from our vocal closeness and intimacy. Again it-is-what-it-is. Such personality ends a double-edged sword as gone is any BA steeliness, so we traded it for this blanket-grain, which is really not a bad transaction when you really think about it. As always I’m taking deficits and making positivity become the outcome.

Next:
Choosing replay of crunchy guitars. Yep, ahhhh. A switch to the number “Episode” from Theatre of Tragedy. We are now in the presence of greatness. The guitars are real but they have added crunch and harmonics. Extra high-pitched electricity………….how else would you describe this sound? And the vocals here, they are perfect in that they are not that forward to begin with. This song goes all out to thrill with imaging of elements way out to the sides of the soundstage! Any lose of pace gets thrown into a kind of swaying groove. This serpentine walk, a stagger, makes-up as we are truly rocking-out. We simply are one with the music. Getting a full-dose of what the song makers had in-store for us to experience.



Treble:
The way they approached the treble is in a way unique. I mean how many Piezoelectric treble drivers do you have in your collection? This obviously affects the midrange too. But that’s the thing, despite any issues, all is connected, all is one. As well as a Hybrid can do. There is off-timbre and yes, it’s not in one area, but is again maybe the effect of the driver? I will make-up a word and call it Piezo-timbre. I mean what else would you call it? Luckily it’s not steely BA timbre, but it does have some metallic essence injected. That’s why everything seems up-piched. Still not an issue, remember this is the best BQEYZ has ever done............ever. It ends with (the treble) being slightly unnatural but forgiving due these attributes. Still I’m enamored with the silky treble embellishments, and just like eating something from the fridge that you’re not suppose to, it all becomes guilty pleasure in the end.

Instead of getting harshness we are gifted with mesmerizing blasts of energy. We end up bathing in such energies and become friends after acclimating to such climates. Is it totally correct and accurate treble? No, but that does’t put a damper on the fun. It’s this exact example of why a slight detour from textbook normal is wanted. On paper this may seem wrong, but character (original character) is the very reason why we buy other IEMs. We are looking for a subtle journey on a side-street, not always taken. And that’s what we have here, a full-on detour from everyday listening. Now you may accuse me of embellishing the off-ness, and in a way I am, except it’s totally musical, so I took that freedom. What matters is the end result.

Technicalities:
The question: Do they have added musicality due to the technicalities or diminished musicality? That sounds like an over generalization, but it's pertinent. Meaning regardless of issues, do the qwerks bring about listenability. Such evasion from truth in replay gloriously aims at fun. Such a timbral artifact becomes endearing and simply apart of what the TOPAZ ultimately is. The character. I make a big deal of it as it's my job. But once your "ON" frequency and on board with the show that going on, it's fine. And.....better than fine if you're into electric guitar music. Such spell-binding alterations bring about a special understanding in guitar replay. Harmonics and overtones are a hyped-up exploration into the true character of the instrument. Why? Because it's done right, yet of higher pitch.

Soundstage:
If guitars aren't creating ruckus, many other items of interest are populating the stage. Such filigrees as synth roll-syncopation follows though, combining full-on connection with other concurrent goings on. But while separation takes place, you will be better off finding a brighter source to fully expound of the inherit potential. Such treble centric or mid centric sources have a big impact on soundstage understanding here. The last thing we want is darker muddy sources adding to any lack-of-bounce or pace. Now much of this talk (you would think) goes against our understanding of piezo-timbre? I mean why amplify what it maybe looked at as a drawback? It is a balancing of sorts, meaning it's better to have the openness regardless of the timbre. Soundstage is slightly above average.

Imaging:
While there is an area in the center which provides less than normal imaging, that's just part of piezoelectric response maybe? At the same time beautiful items make their way out into very well imaged and separated places. I would call the soundstage and imaging slightly above average, though with added dynamics as far as sub-bass imaging and a nice midrange splash once in a while. Obviously the treble being what it is, responds accordingly.

Decay:
Remember we are dealing with Piezoelectric decay. The upper-note attack and fall-off is fairly instantaneous. Such character has acceptability due to the contrasting DD decay. This works as the low-end has a romantic decay showing reverbs, while the total top-half is fast and effective if still missing out on much of the decay.

Timbre:
While slight, it is everywhere. Meaning at times with BA responders, the timbre will be better at certain frequencies and others not. And to give credit where credit is due, there are a few all balanced armature IEMs, that go all-out to parlay this style of metallic hell. Lucky we don't have that. Maybe in-fact the correct timbre is there underneath still, blended with this odd-timbre across the board which seems to blanket the whole of the upper treble and midrange? Only the lower DD sector is not affected in any way shape or form. So (maybe) what is there is both correct but has an extra wax of off-timbre placed on-top? This may sound bad, but can be something you get used to. That combined with the ever so slight piezo-buzzing makes the TOPAZ ultimately what it is.

Pace:
Such gifts are really what this IEM is all about. But remember we have much control over pace with our style of source. In the next section I will get into what a warm or dark source does to the TOPAZ pace, as somehow the TOPAZ is more reactive to such changes? Meaning get the TOPAZ a more linear source and fireworks in pace will follow. Such results are probably from FR, but there is also a way tone affects driver technicalities?

Source responce:
Such a big deal here. While the sound was accurate and full from an iPad, many more dimensions were able to be discovered with a DAP. Such shenanigans were also found up-scaling to a desk-top. Still while authority and bigger sound were found with my particular desktop, there was no cure to the above personality aspects. Meaning lower midrange/upper bass were still recessed, in comparison to other IEMs. The DD is the smoothness and the Piezoelectric is lacking that element. Yet a mid-centric DAP really still brings about the magic. Amazing to all styles of music genre are well performed as all styles of musical quality. Though I will say the TOPAZ is also powerful enough in sound reproduction to show the quality of hi-res playback in relation to 320kbps.


Value:
This is wild as the TOPAZ is way better than the $169.00 BQEYZ Spring 2. Part of it is maybe construction? With the TOTL Flagship Spring 2 build, we were in possession of a work of art. The sleek and gorgeous shells were formed with 5 Axis CNC process, yet maybe they needed the resin build of the TOPAZ? As far as a street rating for the TOPAZ, You probably need look at your library? Meaning I would guess there is better vocal specialty IEMs, even for the TOPAZ price? It actually does Classical well despite the timbre issues, meaning you would think the color of natural instruments would result in calamity? But no, all is well. The missing upper bass presence-relief is an issue in rock especially. In that regard the TOPAZ for me is still a value for all that it does correct, though would not be my only IEM. The value comes in recognizing that no-other IEM is like the TOPAZ. That in and of itself creates a special place in my collection where the TOPAZ is uniquely alone.

The box opening experience:
The included accessories are nice and consistent with the retail price. The cable is especially nice being quite elaborate and well made. I used both styles of ear-tips for this review. There are black narrow bore and two tone wide bore tips included. The black fit better so I stuck with them. The storage case is a nice add, as the cleaning brush. Note when ordering the TOPAZ comes in two colors as well as a choice of the cable coming with 4.4mm balanced termination, 3.5mm, or balanced 2.5mm plugs.



Build:
The top faceplate is 5 axis CNC routed construction. There is a top air-port hidden inside the right IEM letter “O” in TOPAZ, and the letter “Q” in left hidden in the name BQEYZ. That makes four air-release ports as three are placed underside. The TOPAZ is fastened with luxurious gold nozzles with inset shower-head screens. Such big changes for BQEYZ are also noted with 19 individual nozzle openings. The semi-custom form-factor along with the warm-feeling resin-build touching the skin make for a pleasant experience. I can’t imagine the size, weight……….along with nozzle length, being any more ergonomic?



Cable:
4-Core OCC silver-plated cable. The braided cable is made of 7*7 0.06mm litz wire, 196 in total. The 2 pin experience of joining the cable to the TOPAZ was a joy, and could almost be performed with eyes closed.



Conclusion:
Well done. That’s my simple conclusion. In this day and age it’s truly remarkable how a company can upscale their sound. In a way they have stayed with the old design philosophy using a composite single axis “dual” driver. Such progress is exciting, and profitable...............as BQEYZ will surly sell a boatload of these things. If you want to join the party it’s up to you. I can only promise you that the sound is very correct and original. The magic here results from the musicality.

Such easy listening means anyone could take the TOPAZ on a vacation, never wanting more. Times have changed, such a sound was only a dream in past years. While the TOPAZ is not perfect, it’s a statement BQEYZ has stated as a singular vision of fun. Nothing sounds like the TOPAZ. Are these enough reasons to make a purchase? Maybe.

In addition the ultimate reason should be value. Such a value is special, not just for me, but for anyone. Because the tune of the TOPAZ is correct, it’s correct and non-offensive as it could be. When you combine that with build quality and a complete accessory package, good looks and proper-fit you win. You ultimately win!

Declaimer:
I really want to thank Kareena from Linsoul for the opportunity to review the BQEYZ TOPAZ, it does not have to be sent back, unless they ask.

Neutralheads and midcentrics alike, rejoice and be ready to put a smile on your face that this review will be special as this specific type of tuning will be favourable towards some listeners like you who love vocals and instruments focus and a more dynamic yet neutral tuning . If you are a reader of my review articles in the past few months, you are all aware that I admire BQEYZ as an audio company for they deliver a good quality product for the past few years. Their BQEYZ KC2 is still one of the talk-about products that is still relevant despite new products release from other companies.



I have currently have a substantial number of BQEYZ products in my collection and some of them have a diverse implementation of drivers from a single DD flagship of BQEYZ Autumn to a tribrid ones like BQEYZ Spring 2 and Summer and if you want to check out my reviews from some previous models from BQEYZ, check out the links below.

• BQEYZ KC2
• BQEYZ SPRING 2
• BQEYZ SUMMER
• BQEYZ AUTUMN

We are also aware that BQEYZ is taking a few months to release their products just to ensure that it was well-tuned and meticulously crafted. And what I have here is their new product, The BQEYZ TOPAZ.




BQEYZ TOPAZ is the latest and first model from their new product line-up series, The Bird series. It has a hybrid driver set-up transducers that consist of a newly developed 13mm dynamic driver with LCP (Liquid Crystal Polymer) diaphragm paired with a 9-layers of new type of Ceramic Piezoelectric plates. This new type of dynamic driver and piezoelectric driver transducers offers a better bass response, a rich and cleaner mids with less distortion, more crisp and detail treble as BQEYZ promises. These hybrid transducers are encapsulated in a shell made of aluminium on its faceplate and high quality resin on its cavity base which also has structurally similar to their previous model, The BQEYZ Summer and BQEYZ Autumn.




The aluminium faceplate of BQEYZ Topaz's shell has a thin outline on its edges with a rounded edge triangle at the center with a print inside of it (different words of each side, TOPAZ at the left shell and BQEYZ at the right shell). Interestingly, there's a vent hole that was put inside of letter O and Q respectively. The resin-made cavity base is somehow skin friendly as I don't encounter any irritation and its quality is very durable for daily wear and tear use. Another vent hole is also found in this part of the shell too just to make sure the release of some excess air pressure generated from the drivers. The nozzle is made of good quality brass and it is in medium length to fit on most ear for comfortable insertion but this isn't the case into my lug holes as I still have some awkward feeling that I try to do some ear tip rolling (like BQEYZ Autumn, BQEYZ reference ear tips in large-sized is the answer). The passive noise isolation is at least average as I still hear 50% of external noise from the outside sources. Good thing that BQEYZ still implemented a standard 2-pin connector as is more proven to its sturdiness and ease of doing cable replacement.




On the packaging and its included accessories features, we all know that BQEYZ is one of the audio companies who are very generous and conscientious when it comes to that aspect as they included a lot of inclusions that make the customer that they received what they deserved, a high quality of inclusions. The packaging box of BQEYZ TOPAZ has similar size with BQEYZ albeit it is a tad leaner. It has a blueish colour accent with the print " TOPAZ" at the front and some information of specification at the back of the box.The accessories are well-organized inside the box.


Here are the following contents inside:

• A pair of BQEYZ Topaz IEMs.
• 4-core OCC SPC white cable of 3.5mm termination plug with tip plug

BQEYZ Topaz can be driven decently and it can be pair on decent sources despite of the of that 32 ohms of impedance requirement but in a better sources with better output from high quality DACs and Op/Amp will amplify the fullest potential of this hybrid transducer as they really sound even more dynamic and more cleaner sounding in the background.





The tonality of the BQEYZ is more of a leaning towards on a balanced-neutral sound signature as it has that perceive linearity on both bass and midrange and have an enough peak on the treble though they are more of laid-back sounding in the overall presentation.

It's tuning reminds me of an old headphone model from Sennheiser, The HD598. BQEYZ TOPAZ and HD598 have shared similar aspects like neutral sounding with some hint of warmth, punchy bass, well-bodied midrange and smooth treble response.


Here are my observations of each part of its audio frequency range spectrum.


LOWS/BASS:

The bass region of BQEYZ Topaz is intrinsically present in the overall audio frequency spectrum. The bass quality shows more prominent over being a quantitative one. It has an ample punch, sufficient impact and a clean one.


Sub bass has a presence as I discerningly feel its rumble towards its decent depth. Synthesizers and drum machines that we usually heard on electronic music such as EDM and Synthpop has an enough detail to hear their tremorous nature. Mid bass is even more prominent on the bass region as it has a texture to give a well-bodied sound on bass guitars, bass kicks, bass trumpets and bass-baritone vocals. It gives a growl on bass guitar to sound more dark, "earthy" and somber and at least it doesn't sound hollow, an adequate sonorous and resonant sound on bass kicks, a fuller and tinge of tonal colour of bass trumpets and lastly, a guttural and rich quality of bass baritone vocals.


I can say that I consider this one as a "neutral bass" as it doesn't smudges the other audio frequency due to almost to none good control on midbass and certainly that this is not a bass head's ideal tuning due to non-boomy nature and less impact, just an ample thudding.



MIDRANGE:

This is the unequivocally the most prominent part of the overall audio frequency spectrum and it is its midrange both in quality and quantity. It is well-polished, organic and has added ample warmth just to added some texture and density on both vocals and instruments especially on percussive instruments.


Both vocal types of both genders have benefited from that ample warmness. It gives a more solid, deep and power of male vocal especially low-medium octave ones from bass to falsetto. It really shows a detail on how male singers belted the power from their lungs. Female vocals are also projected properly to sound more luscious, sweet, pleasant and clarity. It gives the sense of natural tone and resolve on the contralto to mezzo-soprano types but there is certain type of vocal type that pays my attention and it is soprano's vocal projection. Soprano supposedly has a weaker middle voice and higher pitch which Topaz manages to deliver the sense of energy and intensity decently but I'll be honest on this one, it's a tad inadequate in my ideal standard due to that smoothed edge as a performance of vocal centric IEM needs to reach that higher note to sound airy and energetic. Even so, it's just a minor compromise that I can deal with.


As for the sound quality on instruments, it has that organic but due added warmth unto it, it is somehow less glittering especially on strings but on the bright side, it is now full-bodied sounding. Every pluck of guitar has that clarity but not to point the sound to a realistic crisp. Some certain tracks of acoustic guitar tracks show the inherent characteristic of the Piezoelectric which is added that a sizzle that some listeners might find it "unnatural". Violins and cellos have this cascading sense to have this lustrous, calm and full sounding that doesn't sound muted nor veiled. Brass like saxophone and trumpets has still this metallic and intense characteristic to sound closer to being natural. Woodwinds like fife and flute has this rich and airy sounding but sometimes a bit soft as you will determine everytime the flautist blows its headjoint. Pianos has this warm, luscious and rich tone that reminds me of some antique German grand pianos. And lastly is how snare drums sound like, it is penetrating and shuffling but it has this softer impact.


As I'm a bit biased towards on midcentric tuning, this is indeed a highly recommended type of midrange tonality on how the mids are presented in a smooth manner, well-bodied and has sufficient details. Midcentric will absolutely love its quality and quantity.



HIGHS/TREBLE:

Another thing that BQEYZ Topaz surprises me on how it handles its treble registry. As we expected of a piezoelectric driver's typical characteristic which is that zingy sizzle feel to give some listener a sense of airiness and sheen in the brilliance region but expense of being too strident and artificial to some treble sensitives, but BQEYZ manage to tamed down those peaks while retain the shimmer and good extension of treble air. The fact that the treble delivery is rather smooth and relaxing.


Upper mids has still some noticeable peaks but not to the point to make a sound more strident and sibilance was keep under controlled and very minimal to none to be noticeable unless it was a sibilant-laden tracks that Piezoelectric drivers make it more pronounce but not that unpleasant hissing that make us annoyed with.


Cymbals strikes definitely has a more lustrous and undulating sound with some substantial amount of shimmer but there's a snag about it, it lacks snap and is a bit dull in my ideal as I wanted a more solid and glistening sound on hitting and crashing on cymbals. Despite on my reservation on how cymbal sounds was portrayed, Piezoelectric managed to deliver a good treble extension with a sufficient amount of harmonics and air.



SOUNDSTAGE, IMAGING & OTHER TECHNICALITIES:

As we all know, Almost all BQEYZ products' strength lies in excellent technical performance and TOPAZ is no exception on this one. The overall presentation of its sound field is well-proportionate. It certainly has a wide soundstage, a good immersive depth and a good height ceiling reach which I classify it as cavernous.


Imaging is good for a single DD as you can locate the precise positioning of instruments and singers but in a more typical stereo panning manner. Separation is also commendable on this one it has a good gap and spacing of each instruments but there is one element that pays my attention and it is its layering capability, the arrangement each note in every part of audio frequency sprectrum doesn't define well on emphasizing of its respective sonic information that causes some inconsistencies on the mix. It's just a slight nitpicking in my part as I tested some of TOTL IEMs with superb technical aspect in the past few days ago. But for its price value, it is just fine.


Resolution capability-wise, it is adept at resolving some nuances and details either on micro scale or macro dynamics. But in overall presentation, it is a bit smoothed out, a less aggressive definition that will also influence the timbre to have a smooth and organic tone with a tad of warmth.


As for coherency of drivers, the tandem of dynamic driver and piezoelectric plates seems to perform a very cohesive performance to the overall frequency spectrum that it deliver a faster, dynamic sounding with nimble transient response and the zesty nature of Piezos seems to have been suppressed and even less distorted probably due to newer composite materials of Piezoelectric plates.



PEER COMPARISONS:


BQEYZ SUMMER

• Both are very comparable due its implementation of Piezoelectric drivers but Summer has additional balanced armature to handle the midrange. Shells on both SUMMER and TOPAZ are in contrast as the aforementioned product is made purely of resin while the latter has a mixture of aluminium for its faceplate and a resin for its cavity base.

• SUMMER is more V/U-shape sounding while TOPAZ has balanced-neutral presentation. Summer has a more aggressive approach when its comes to tonality while TOPAZ is more laid-back and relaxed. Maturity of piezoelectric driver seem to be an advantage of TOPAZ as it really sounds more homogenous over a bit divisive sounding of SUMMER to make it a tad incoherent.

• SUMMER was more pricey when it was released a year ago and TOPAZ pricing is more competitive and affordable.

TANGZU/TFORCE YUAN LI

• YUAN LI is more expensive than TOPAZ. YUAN LI's shell is made of aluminium alloy that it is more hefty to wear compared to a tandem material of resin and aluminium alloy of TOPAZ which is lighter and easy to wear into the ears for a long time. Both are comparable of providing of a good set of inclusions.

• As for tonality, both have balanced-neutral sound signature, but YUAN LI is tad leaner on overall presentation compared to a more textured Topaz. YUAN LI is more focused on sub bass while TOPAZ has more accented mid bass, mids is leaner and probably has more clarity on YUAN LI while TOPAZ approach in a different manner which is a more bodied and yet smooth mids. Both of them have smooth treble registry but TOPAZ definitely has more air.

• As for technicalities, YUAN LI has better layering and imaging while TOPAZ has a better soundstage. Separation is similar as both of them have good spacing. As for resolution, certainly YUAN LI has more defined on details as they have more edgy definition as TOPAZ has a smoothen one.

MOONDROP KATO (Gold Nozzle):

• KATO is definitely more expensive than TOPAZ, KATO shell is made of stainless steel which is more durable than TOPAZ's hybrid sandwiched materials but it is more on a hefty weight that might add some stress on wearing them for a long time. Wearing both of them is also a bit problematic into my lug holes but KATO has a more shallow fit given that I've tested it with a Moondrop Spring eartips.

• As for tonality, KATO is more of a lean U-shape sound signature which also affects the quality and quantity of mids. KATO bass is leaning more on sub bass as you will feel a more grumble and seismic sound while it has thin mid bass that bass kicks and bass guitar sounds too transparent and light, almost no texture at all. TOPAZ indeed delivers a better bass quality. Mids is definitely recessed on KATO compared to TOPAZ as male vocals and instruments are lacking in texture and definition. Only female vocals seems to have a better clarity and more open but too transparent on texture is also an issue. Treble registry-wise, KATO has more brighter and shimmer as I notice upper mid peaks that I encounter in some tracks, especially on female vocal ones but it has lesser treble air extension when I compare it to TOPAZ which has smoother and better airy extension.

• When it comes to technicalities, TOPAZ is better than KATO in most aspects, from Soundstage to Imaging. KATO has only average to above average soundstage and imaging and seperation are just meagre and a bit too linear in my liking. As for resolution capability, both have different approaches, KATO certainly has more edgier definition while TOPAZ is more softer but surprisingly, TOPAZ has better detail retrieval.

As I end my assessment on BQEYZ TOPAZ, BQEYZ once again manages to deliver on such a phenomenal product. For sure that this is not a perfect product as there are still a few things that need to be polished on this product but its well-done tonal maturity and good technicalities will outweigh those flaws.


Current competitors in this price range still seem to follow those more hyped tuning curves like Harman or its derivatives (Geez, it's just another modified U-shape all over again.) But this is what I like on BQEYZ's philosophy, they don't follow the trend, they try to create their own path in audio world industry that they manage to win some hearts and minds to some audio enthusiasts out there.

I am not affiliated to BQEYZ nor receive any monetary incentives and financial gains as they provide me a review unit for an exchange of factual and sincere feedback from yours truly.


Once again, I would like to thank Elle Zhou for providing this review unit, I truly appreciate her generosity towards me and other reviewers.

BQEYZ Topaz- "A gentle
Whisper"



DISCLAIMER:
I bought TOPAZ for a discounted price in exchange for an honest review. I would like to thank Ms. Elle Zhou for giving me a chance to review them. She did not reach out to me. I reached out to her because I am a KC2 fan. So that is the first bias there. I do not accept affiliate links, it gives me too much pressure when writing, it’s not fun. It feels like work.

That is why, please take my review with a grain of salt. I know it is bothersome in your end to read more reviews for one product, but trust me, it is better that way. So please consider reading and watching other reviewer’s work.
I consider this as my diary wherein I lay out my listening impressions with the Topaz. Some sound impressions might be a product of my mood, body conditions, amount of sleep, and bank status.haha

MY VIEW on BQEYZ:

BQEYZ KC2 is my second IEM when I started this hobby. I still have my KC2 now, and in rotation. We have a cult following on facebook haha. So yes, that is the second bias.

The company is very innovative in my opinion. They have patents on their products. They don’t release that often so I think they use most of their time developing.

They got VGP awards on their spring 2 last year and on their Autumn last month. What is more surprising is, they don’t even have a distributor here in Japan, but still managed to impress the critics.

They provide very good quality products. They have very good aftersales service, and they check channel imbalance before packaging their units. See their facebook page.

They are very consistent with their tuning. The bass shelf transitioning to mids is their signature, so it has its own "character". Which means, they believe in what they are doing and they are improving in every release. BQEYZ certainly has direction, and I like to put my money on a company like theirs.

PACKAGING and ACCESSORIES:


The packaging is neat and properly done. Very generous.

What you get inside:
-SML regular bore tips
-SML wide bore tips
-circular IEM case
-one cleaning tool
-very very good quality cables. It says, “4 strands single crystal copper silver plated cable, 0.06mm wire cores, 7x7 strands”, whatever this means.. Anyway! this might be the best looking cable I have in my collection.

BUILD and COMFORT:



-they fit pretty well on my ears. They have fins but are angled differently. I did not notice any discomfort even with hours of use.
-they are very light and the build is tough to feel. Nothing wrong here really.
-design wise, it says BQEYZ on the left side, and TOPAZ on the right. Ahahaha I am not really sure why I indcluded this. I am so not used to doing this kind of comprehensive reviews on builds and accesories.

SETUP


-Shanling M3X using UAPP, Hiby ang stock player

-Different tips used including Radius Deep Mount, Moondrop spring tips, and Kbeae07. Stock tips are fine. The regular one is a bit bassy for my taste, and the wide bore M size does not give me a proper seal.

-stock cable and **** 8 core balanced.

-Volume measured and listend at 75-78 dbs.

I listen to more, but I can’t just list them all here.haha. Just giving you an idea on what I listen.

SOUND PROFILE:

Warm balanced. This set is very smooth sounding with emphasis on lush and warm mids. I don’t hear any piezo zing or harshness. Vocals have good presence, not overly forward and definitely not recessed. At times, I feel like it is approaching a pseudo-flat sound.

TOPAZ is not subbass focused so you don’t hear much rumble. It is fairly linear in terms of transition. Pseudo-neutral I would say. They are soft in presentation and for my ears, they sound like BA bass. The decay is on the relaxed side as opposed to being snappy. Because of this, the midbass does affect the timbre of mids especially around 200hz-600hz.
That boost around 200-600hz makes mids sound thick and velvety. I can see how some people might call this bloat, but personally I don’t hear them to be altering that much in the mids, because as I’ve said, the bass has this soft presentation to it. This results to an exceptionally smooth and warm tinge on vocals.

Vocal presentation is favoring males. Not because of the boosted lower mids, but because of the upper mid scoop around 5-6k. Harmonics are cut in this area so female vocals might not sound complete and angelic. Rather, female vocals sound emotive and fatigue free.

Treble is in the smoother side. Honestly, I feel like the piezo is not contributing much in the treble other than adding that extra air and spaciousness in stage. Details in the treble are softer in presentation. Not dark, softer. What I mean by this is that, somehow the fundamentals start with good presence, and then harmonics are cut with that 5-6k scoop, and goes back for air. So you get warmer details as opposed to being sharp. I say warmer because they are present and are not buried, only that they are not sharp sounding. This can be really good for people who are treble sensitive, because Topaz is really really smooth in that area. I’ve tried it with all my harsh and sibilant tracks and all of them are tamed down like a masochist begging to be whipped.

HOWEVER. After asking the burn in gods for help (mental, physical, copium). The treble sounds exceptionally crisp and complete, but still soft.

Soundtage is wider than deeper. They are really wide, probably the combination of thick mids, forward vocals and smooth treble makes up the whole scape. Imaging and layering are average. It has something to do with its overall tonality. The openness it renders is very close to how earbuds and headphones sound for my ears. Again, for my ears.

PROS

very realistic vocal space. Not the “in front of me” kind, but “live session” kind.

the vocal presentation sounds like Tangzu shiminli but there is no shout AT ALL. I tried this with Celine dione tracks like “All by myself” at around 2:43.

Very good reproduction on the vocals of the track “Imahe” by Magnus Haven. The male vocals just sound so lush and organic. The warmth from the lower midrange gives it a more realistic timbre.

Listening to “Dressed to Kill” felt very atmospheric. Because of the very wide stage, instruments seem to have their own space and they are very easy to locate.

Even if the treble is not forward, it is properly resolved. The cymbals on the track “suroy-suroy” do not have unnatural splashes.

Oh man, “here without you” by 3 doors down is absolute heaven. The guitars, the vocals, ride cymbals. Demmmm.. The air in the upper treble really helped in giving this song a lot of life.

I thought the track “Bukod Tangi” was very calming with very good balance of frequencies. Nothing pops out and overpowers.

very good vocal reverb on Olivia’s “favorite crime”. Again, I felt like listening to her live. The way she enunciates is perceived as very emotive, paired with that acoustic guitar, I could feel how she is relaying her emotions in that song.

GOAT by Polyphia was very nice to listen to. The cymbal strikes were very crisp and detailed. I noticed this during my 5th day of listening. So probably the drivers have settled? Or mental burn in kicked in? or I was just loaded with copium. You be the judge.

“Dive” by Ed, Edd and Eddy sounds so realistic with very good center imaging.

I don’t know it is a pro, but they really give me an impression of how earbuds and headphones sounds.

CONS

soft treble body. I easily noticed this in all my tracks. Although it is really not an issue for me after more than a week of listening. I just thought this is worth mentioning especially for those who prefer sharper transients in the treble.

Soft bass attack. Same as the treble. They do not sound like the usual DD slam. I am pretty sure this has something to do with the piezo and the tuning as well. But yeah, as I have mentioned in my first impressions, they sound like a BA bass. Not that it is bad, because they are actually good at resolving the lower notes, but it is something that you have to keep in mind and get used to. Personally, I do think the bass is the Achilles heel of Topaz. It lacks that impact and realism and it seems that it does not meld together with the balance at times.

in the track “just a phase” by incubus, Topaz sounds congested on that drop at 4:22. Maybe because the stage is wider than deeper, so layering suffers a bit on heavy riffs especially when the guitar goes in at 4:48, it was a bit hard to distinguish the chords.

in the FR, the drop at 10k kills micro dynamics. This can affect timbre on cymbals, snare snap, and string instruments.

in the track “you were trouble” by Taylor Swift, Topaz was a bit struggling to resolve details at around 2:48.

even if it has a lower basshelf as compared to bassy and muddy sets, Topaz sounds oddly veiled, probably because of the upper mid scoop.

ONTO the TUNING of THIS PIEZO

BQEYZ defenitely tamed this piezo down. I haven’t heard their springs and summer. I was actually looking forward to that sound and I was ready for earrape haha. But these Piezos resolve things differently. How Topaz presents treble is very unique. Very soft but almost the same presentation as planars, albeit not as detailed (I have only tried p1 plus and muse power hifi). This also gives vocals a very good space and air.

However, I am not sure if I get good coherence with this piezo. I mean, I can definitely notice the shift on timbre in the higher treble. The combination of this LCP and the tuning of this piezo is something new to my ears. This doesn’t really result into a bad listening experience. Probably my ears got used to the coherence of single DDs, and topaz somehow gave me a different presentation. It’s not bad, just something to note on.

IS THIS FINALLY THE UPGRADE OF KC2?

Only KC2 lovers will understand this part. You can skip this.

So the answer is YES and NO. The tonality is uncanny. I am pretty confident they WILL graph very close. I don’t even need to see graph comparisons to know. The way it handles vocals and the mids is even an upgrade in the Topaz. The Topaz even has more forward sounding vocals. Although KC2 may have bit more sparkle up top, it can be a bit gritty and unrefined. The piezo of Topaz is not a slack. It is not inferior, but it just handles the treble in a different way. More refined, gentle and just a pleasing experience to hear overall.

Soundstage is also wider with Topaz. Basically, this is a warmer KC2 with upgraded techs and a more laid back sound.

However, the gentleness and softness might put you off. Layering and imaging on KC2 seem to be a bit better as well, probably because KC2 is a 2DD+ 2BA?

So yeah, it is hard call hahaha. Okay okay, if you do not have the budget yet, maybe you can stay with your KC2 for now. But if you really want an upgrade without breaking the bank, mmmm, yeah I think Topaz fits that description, just take note of what I mentioned.

FINAL THOUGHTS:


I honestly thought this pair was meh. BUT slowly, every day, I am beginning to really love this set, especially how it presents treble.

Its gentle lap dance is very addicting. Maybe its copium? Haha. There are definitely sets that I really don’t like even with loads of copium, but not the Topaz. It offers a different approach in this flooded harman curve sounding sets. If you are in for music indulgence, fatigue free treble and good sounding mids, then BQEYZ TOPAZ is a safe recommendation.

The tonality just prevents you from doing critical listens, so if you are looking for a critical listening set, this may not be for you. Not that the Topaz is less detailed, No. Topaz has details but softer in presentation.

Just like how your girl gently whispers in your ears when you're in a loud cinema,

“I am alone tomorrow”. -Gentle, but you heard her right..haha

=============================================================================================================
Sound signature:

• The BQEYZ Topaz presents itself in a laid-back, balanced sound signature at most, with a hint of warmth. Its smooth, laid back approach makes it different and is a complete opposite to the BQEYZ Summer’s bright, energetic sound.

Lows:

• The lows in the Topaz are bodied, controlled and are slightly elevated. However, I wouldn’t call it a bassy IEM because it is not energetic and leans to a more calmer presentation. Subbass is a bit elevated compared to the midbass. Decay leans to the faster side and is able to keep up with the bassy tracks but will sound lacking with bass heavy tracks. Bassheads may look for another IEMs, or may try the Summer.

Mids:

• Despite having a laid back sound, the mids here on the Topaz are not distant nor too forward either. It is somewhat “correctly placed” with some instances of forwardness of male vocals on some tracks. The lower mids are warm, smooth, and thick but never sounded muffled. Upper mids here are ever-so-slightly elevated and has good clarity and sparkle. There is still some slight hint of “piezo zing” here in the Topaz but is greatly reduced and rarely shows itself in very sibilant or poorly mastered tracks when compared to their previous IEMs, namely the Spring 1, Spring 2, and Summer or if you use it at higher than usual volumes. For example, Red Velvet’s “Feel My Rhythm” is a bright-sounding track in nature and may reveal some peaks or sibilance depending on the gear used. When listened to with the Topaz, any hints of harshness or peaks are absent for the most part. Overall, the mids here in the Topaz is what I really like the most - it reminded me of BQEYZ KC2’s mids, but greatly improved in terms of its presence, thickness, and naturalness. The mids here are a bit more spacious than the KC2 while keeping the details and thickness to its peak quality.

Highs:

• The treble here in the Topaz are decently extended while avoiding any harshness or peaks. However, I would like a little more air in this region for the cymbals to have that satisfying crash and splash but for the most part it sounds “natural” and never sounded rolled off or lacking. Detail retrieval here is also above average as you can hear the microdetails fairly easily.

Soundstage, Imaging, and separation:

• The soundstage here is wide - if not the same as the BQEYZ Summer. It is wide with above-average levels of expansion. It is wider than deep with a decent amount of height. It sounds like you’re in a cinema or in a concert hall if you use your imagination while listening to it. Separation here is also near identical to the Summer as it can handle very busy tracks fairly easily. Imaging is better on the Summer by a very small margin as the Summer is a bit clearer in vocal and instrument presentation. Do take note that the Topaz is still no slouch and can present instruments and vocal position precisely.

=============================================================================================================
Vs other IEM comparisons!

Vs the Audiosense AQ0 (100 USD)

• The Audiosense AQ0 sounds more energetic and alive than the Topaz is also bassier. The lows on the AQ0 are much more elevated when compared. The mids on the Topaz are forward and smoother in presentation when compared to the AQ0. Treble here in the AQ0 also has more air and extension. The soundstage is wider on the Topaz while the AQ0 is better on the imaging. Separation are nearly the same.

Vs the Tri Meteor (100 USD)

• The TRI Meteor aims for a more harman-ish (u-shaped) sound signature. Its lows are more elevated, thicker and slower in decay when compared to the Topaz. The mids are also veiled and recessed on the Mirror. The treble lacks air on both IEMs but the Meteor has lesser air when compared. The soundstage is wider on the Topaz and has more depth. Separation and imaging is also better on the Topaz. The Meteor is a bit harder to be driven to its full potential and will be needing a powerful source, or even an amp in some cases.

Vs the NF Audio NM2 (100 USD)

• The NM2 is again, energetic and much more alive when compared to the Topaz’s laid-back sound. The lows here in the NM2 are more controlled and has better decay and texture. The mids here are also more articulate and energetic on the NM2. The treble is also airy on the NM2. As for the soundstage, the Topaz is wider and their separation is nearly the same. Imaging is better on the NM2.

=============================================================================================================
Pros:

• Smooth, inoffensive sound.
• Managed to fix the “piezo zing” by a huge amount compared to their previous IEMs aside the Autumn.
• Thick overall sound presentation.
• Controlled, meaty lows.
• Smooth, slightly forward mids.
• Non-lacking, decently extended treble.
• Very good technical performance in its price point.
• As always, decent presentation of packaging and accessories.
• Very good fit and isolation. BQEYZ knows how to lessen the occlusion effect.
• Thick, sturdy stock cable. Even thicker than their current flagship’s stock cable.
• Responds well with better pairing/source (e.g, Topaz with a fairly powerful, neutral source).

Cons:

• This IEM’s laid-back sound will not please those people who want an energetic sound approach.
• The “piezo zing” is still present, but greatly lessened when compared to the Summer and Spring 2, and will only be encountered with poorly-mastered tracks or when used with higher than usual volume.
• Treble could be a little more airier to my liking.
• Imaging is slightly below the Summer in terms of quality (a nitpick).
• Shallow fit may not be for everybody (but not for me though, still subjective).

Verdict:

• The BQEYZ Topaz is quite a surprise for me personally since I thought this was gonna be the “KC3 '' or the “Winter” of their lineup. However it seems to be the polar opposite of the BQEYZ Summer in terms of sound. The Summer aimed for a brighter, fun sound while the Topaz strikes for a more relaxed, laid back, smooth sound. Despite being a “neutral” type of guy, I like this IEM because it reminded me of BQEYZ’s early days - where the KC2 differs itself from the competition. In this case, it is quite different from what we’ve seen and heard from them recently. The only thing that didn’t change is the fact that they keep delivering very good sounding IEMs catered to every preference of the masses. I recommend this IEM for those people who prefer a fatigue-free, balanced-warm sound signature. And for those who like a purple IEM too!

Pairing recommendation/s:

• Source: The Topaz benefits and scales well from a fairly powerful source. I recommend pairing it with a fairly powerful, neutral source. A dongle will do as long as you maximize the 2vrms output of your dongle, if possible.
• Eartips: The stock eartips are more than enough for most of the time and very comfortable. However, you can always use your preferred aftermarket eartips.

This is my BQEYZ Topaz review on this website.

My first encounter with BQEYZ Audio is the KC2. when you look at the graph of KC2 it looks weird but BQEYZ proves me wrong since the sound of KC2 is pretty good for me. Now, this is my second encounter with them regarding their new product which is the Topaz.

Background about me and personal taste in music.

I am a student and currently a hobbyist in the world of audio. When it comes to my sound library. I am more in anime songs and jpop artists (but not all jpop artists). I usually play rhythm games for example. Bang dream, D4DJ and OSU.

Anime related to the pair

The topaz reminds me of myriad colors phantom world since this pair has a fun factor in its sound. Like the anime it’s a fun anime with drama and action, This is also the feeling I got with topaz. In general speaking, the topaz feels like I am in a series itself.

Before I start here are my disclaimers

The unit I have is a touring unit and in short loan unit.
I didn’t gain any monetary reward in this review. My reviews are all mine and based on my experiences.
We have different hearing capacities so expect a different outcome from me.
I am a budget reviewer and I review based on the sources I have as of now.

Reasons to buy the Topaz(Pros)​

Fun sounding and can be an all-rounder.
Balanced sounding leaning to warm.
Very safe for ears that have low tolerance in higher frequencies.
pleasing mids.
Great bass quality.

Reasons to avoid the Topaz(Cons)​

Not a technical set.
Treble may lack air and details to some
Imaging may be better
Separation may be better
Mids are not that engaging unlike with kc2. kc2 has more engaging mids.
female vocals need a bit of emphasis (nitpick)
very safe treble losing the details(subjective)

Personal Sound preference​

mid-centric guy. or neutral balanced with an emphasis in the mids. my other sound preference is U-shaped which means an emphasis on the low end and high end.

Build and Design​

the Topaz is built with resin and the faceplate is made out of aluminum. but even though this is resin and faceplate with aluminum it’s not a cheap plastic resin. it feels like expensive grade plastic resin.

Packaging and accessories​

It feels like I am unboxing a phone. Since the box is slim and not that big. Inside the box is a set of ear tips it has two types, bass, and reference it has an included case. The stock cable of the topaz feels like a top-of-the-line cable.

Sound signature​

The topaz sounds warm-balanced in my other sources. while in my OPPO A95 the sound is U-Shaped no dongle for this one.

Lows/Bass​

For me, this is an upgrade to the bass response of the KC2. KC2 has that tight and punchy bass but with Topaz, it feels like KC2 with elevated bass with texture. Since the Topaz is a warm-balanced sounding IEM. Sub-bass is punchy for me but for bass-heads that want aggressive sub-bass. this might feel lacking for your taste since the sub-bass of topaz is more controlled and bodied. Mid-bass is also great it does not bleed even on busy kinds of tracks. I tested the topaz with rhythm games that I played. I was surprised since the bass is balanced. in general Both kc2 and Topaz have tight and punchy bass. for me, Topaz is the winner between the kc2 and Topaz.

Mids​

This i both kc2 and topaz have great mids. The kc2 has balanced emphasis in the vocals both male and female shine it’s also the same with Topaz. but Topaz has more thick and heavy mids which means male vocals will be happy cause it’s their time to shine. female vocals still shine but have an average presentation. in the track of pop team epic and inner urge by Sumire uesaka. her voice feels lowered but not too much her voice is still expressive but not that expressive with kc2. It is also the same with my OPPO A95 male vocals still win compare to female vocals, Now KC2 or Topaz. both are good in the mids kc2 has lush mids while the Topaz is more on the warm side.

Highs/Treble​

Topaz loses here The reason is KC2 has more treble extension and a wide variety of details. but with Topaz the prominent details I can hear are more in macro details. but it still has the presence of micro-details. Topaz lacks the air for both male and female vocals while in the KC2 both Male and Female have air for me. In general KC2 wins here based on my sound.

Soundstage, imaging, and separation​

Topaz also loses here, The reason is the soundstage is more on average but with a bit of depth. but in kc2 it’s very wide and has more depth in staging. so for the battle of the soundstage kc2 wins here. Imaging in the topaz is great but not as great with kc2. in kc2 the imaging is well detailed but topaz is not that bad it still can handle heavy busy tracks. like infermata from spotlight kids. battle of imaging kc2 wins. in separation, it’s a close battle but kc2 wins kc2 has more depth in separation.

Final Ratings.​

Bass:5/5 happy around!

Mids:3.8/5 almost

Highs: 4/5 are you ready

Technical aspect: 3/5 good enough

Conclusion​

The pair is a brother to the KC2. but Topaz is more like a mature brother since Topaz has a feeling of being like a big guy.

Closing​

I would like to thank BQEYZ Audio for the review sample. also for arranging the review tour.

You can find this review at http://www.mobileaudiophile.com/ and I am usually active there.

BQEYZ Topaz

BQEYZ Topaz is the latest offering by the Chinese-company BQEYZ with a 9-layer piezo electric unit, 1 dynamic driver, and an LCP Diaphragm. Almost the same configuration as the Summer, except the summer only has a 5-layer PE unit.


DISCLAIMER :
This is a loan unit that is currently on tour. I did not receive any form of compensation from BQEYZ. As always, I'll ensure to be honest with my review.

Pros:
Good bass texture
Euphonic mids
Relaxed treble
Wonderful package
Balanced leaning to warm sound profile

Cons :
Too much friction on the eartips which irritates my ears, tendency to not let it go all the way through (personal issue)
Treble may lack air and details to some
Imaging may be better
Mids may not sound engaging and forward



PACKAGING :
BQEYZ never fails to give me a wonderful unboxing experience. As usual, Topaz has a 6 pair of eartips. The black tips are narrow, which improves bass. The clear eartips have a wider bore which emphasizes a reference tuning.
One thing I should note about the eartips is that there are times I find it uncomfortable and irritating, also very hard to push it all the way in, not pertaining to deep insertion but to the recommended depth, which does not give
me a good seal despite using the smallest size possible.




Anyways, enough of the tips. Next, we have the case, inside the case we have the cables, and a brush for cleaning.



BUILD 5/5 :
The faceplate is what I believe would be aluminum with a matte finish with filters on the letters O and Q, I would like to believe that these are filters. The rest of the shell is somewhat similar to what the Summer's material is. The cable is a silver braided cable. The build of this IEM feels robust and light, so I don't
have any issue against the build quality of the product so I am giving it a 5 out of 5.

BASS 5/5
The bass is not lacking and not too much for my taste. It is balanced with enough texture, mid-bass are thumpy, and thick. It just doesn't have that excessive sub-bass rumble and impact that you would experience from bassier IEMs. If you are a basshead I believe you may have a love-hate relationship with this IEM.

Definitely a 5 out of 5, bass is wonderfully balanced with enough energy to make it not sound too bland and not to excessive to the point that it bleeds to the mids, or worse, produce a muddy, muffled sound.
Just enough thump, and slam to keep that music listening experience alive.

MIDS 4/5
Mids offer the right amount of liveliness and an emphasis of pleasant richness instead of accurate, lively sound. It still sounds natural but a bit on the thicker/slighly warm side. Male vocals would favor this tuning due to its warmer approach. Female vocals still sound good, and engaging. Overall, the mids are relaxing, and rich with an evident but subtle "zhing"/"zest" of the piezoelectric unit on the upper mids on [Chandelier - Sia] and [The Days - Avicii].

A wonderful 4/5, I really like rich and thicker mids since they are more inoffensive in my ears but sacrifices some details along the way.

TREBLE 3.5/5
Because of the warm approach in this particular IEM, I have good news for you treble-sensitive peeps because unlike the Spring II and Summer in which you can really feel PE units working that "zest" and "zhing"
in the higher frequencies. Treble on the Topaz is more relaxed and inoffensive. This safe tuning has some downsides though. Some tracks don't shine as they should, [You've Got To Have Freedom - Pharoah Sanders] is the track I use to test treble response and
is not performing well at its peak performance. Percussion instruments on some tracks doesn't have that much impact and splash.

I am giving the treble an average 3.5 since its not bad nor great.

SOUNDSTAGE and IMAGING 3/5
Soundstage is good, but not that overwhelming. It has enough width to separate instruments and give enough space to not make them sound too compressed. Imaging is surprisingly okay, it can handle
busy tracks well like [asphixia - Co Shu Nie]. Aside from that, there's nothing worth writing home about the soundstage and imaging of the Topaz. It's just okay.

Comparison to other BQEYZ units I've tried:

BQEYZ Summer : BQEYZ Topaz has thicker texture, BQEYZ Summer's bass does not affect the midrange. Summer vocals are more forward, and clean. Treble is more airy, detailed, and crisp. You can really feel PE unit's "zhing".
Basically, Summer is the opposite of Topaz. While Topaz delivers balanced overall sound, euphonic vocals, and safely tuned treble. The BQEYZ Summer is a brighter version compared Topaz, not excessively bright but you can hear their difference like night and day. Topaz is also more suitable for longer listening compared to Summer which gets fatiguing due to its upper frequency elevation.

BQEYZ Spring 2 : Bass is lighter, mids are more articulate, detailed, and forward comparing to both Topaz and Summer. Treble is present, if you want to feel piezoelectrics at works Spring II is your go-to earphones compared to Topaz.Spring II is balanced leaning to bright, while Topaz is balanced leaning to warm.

BQEYZ Autumn : I have tried the Autumn from a friend but I don't want to give a comparison between the two since I haven't tried or have been exposed to the Autumn to make a comparison. However, if just from the neutral filters alone, Autumn is a clear winner.
