Intro

BQEYZ is new on the Chi-Fi market, at least under this name. They currently have 4 models in their luggage, whereby the KB1 with its three drivers is the "smallest" model. The review is one and the same as that of the YINYOO NY-06 because they are exactly the same headphones. Both companies seem to have used an OEM version and only the outer plate is slightly different.

Handling

As already mentioned, the quality, i.e. the materials, design, and workmanship is excellent.
In the same breath the Revonext QT2/QT3, KZ ZS6/ZSA, TRN V80, YINYOO NY-06, as well as the other models of the BQEYZ series are mentioned.

The included cable is similar to TRN's cable with preformed earhooks, but has a better positioning of the Y-Split. There's nothing negative to report here, it's simply a very good standard cable!

The wearing comfort is comparable to the above-mentioned models, where you could notice that the in-ears are noticeable because of their metal construction, but this is not disturbing.
The package content is limited to the most necessary, with silicone tips, cables, and the in-ears, but not everything has to be decorated with gold leaf, rhinestones or a vacuum cleaner. Better this way and good in-ears than the other way around.

Sound

The sound is basically comparable to that of the Revonext QT2. That means the KB1 is very good! If you start from the same drivers, you may be able to explain the differences by the different construction methods.

The bass is rather middle bass heavy, but can also go much deeper and with a lot of pressure. Because the bass is already preferred, we have a slightly unnatural warmth in the music. When it is demanded by individual tracks, it really rattles in a positive sense.

The mids have great clarity, can also score with details and are simply round! Also here very close to the QT2, but I would describe them a bit cooler and more exhausting at high volume because then they already go quite a long way. Basically, we're talking about a classic V-signature. The voice reproduction is good for both sexes.

The treble is clearly above the mid-range, especially in the lower region. This makes them stand out well on the one hand and also contributes to a wider stage, on the other hand, it is a bit tiring in the interaction with the mids at a higher volume. A little more brilliance at the top might not hurt either, but they are very well positioned for the price range. That's a really high level of complaining because the KB1s are great in-ears with bass head factor and also audiophile.

Outro

The comparison with the REVONEXT QT2 is almost identical. I would prefer the KB1 for bass and stage, but the QT2 for treble and midrange. If you now add the TRN V80 or the KZ ED16, which are also convincing in all frequency ranges, the KB1 is at eye level. In addition to its sound, it also convinces with its quality. GOOD WORK BQEYZ!

UPDATE: The Head-Fier Otto engine compared the frequency response of the NY-06 (KB1) and the QT2. These are almost the same if you consider the measuring tolerance. The minimal sonic differences can only be explained by the different construction and fit".

Legend

Haptic:

Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.


Value:
Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
