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The concerned IEM is the BQEYZ TOPAZ; although being a bit out of date, its internal piezo technology makes it quite intriguing.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

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.
