?10mm Dynamic Driver


One of BYZ's best-looking earphones, the K53, have turned to be mediocre when it comes to sound clarity.

They sound similar to BYZ K30, but with a more impactful bass (even though slightly shallower compared to K30), but much darker highs.


  • Great bass response, especially mid-bass.
  • Amazing build quality and design. Braided cable and shinny metallic housings? Count me in.


  • The mids and highs could use more detail and brightness.
  • The mid-bass is quick, yet the sub-bass isn't deep enought to follow.
  • The included tips might not be suitable for everybody.
  • It might be a factory mistake, but it seem like there aren't any large-size tips.

Comfort & Fit

The included tips are very simple and very soft. They might not fit every ear. I didn't have any trouble, but you should consider using different tips of your choice.

Lows / Bass

The bass is awesome. It's quick and impactful, but not as deep as I would expect such impactful bass to be. These are mainly mid-bass dominated, so a bit more sub-bass and less mid-bass could make these earphones' bass perfect.

Mids / Vocals

The mids are not the most detailed mids around, nor the most accurate, but they will satisfy the avarage consumer. What bothers me is that they're recessed and at the same time not tonally accurate, as in quite a bit dark.

Highs / Treble

BYZ did a good job when it comes to avoiding sibilance. However, much microdetail was lost in the process. Still, most avarage consumers will find these highs quite adequate as they are, but if you're looking for a detailed pair, these earphones are not for you.
