BYZ K30
ø8mm Dynamic Driver

Loud sound, monstrous bass, sharp highs and even a solid build quality and design. These are V-shaped earphones done right, even though the highs are slightly over-done, as they tend to be relatively sharp and even sibilant.

NOTE: This model was most likely discontinued. It is very difficult to find for purchase.

Pros
Cons
  • Insane bass quality and depth, and loud and crisp highs. The mids are decent as well.
  • Robust build quality and an attractive design.
  • The mids sound slightly darkened and sometimes sibilant.
  • The cable was folded tightly inside the package. Never do that.

Comfort & Fit

Lows / Bass

The bass of these is loud and gets very deep. The sub-bass is amazing. Perfect for electronic dance music.

Mids / Vocals

The mids and vocals are somewhat dark and very recessed. Most listeners will not be satisfied with underemphasized mids and vocal performance.

Highs / Treble

The highs are crisp and loud, but also tend to get a bit too sharp, even occasionally sibilant. The detail level is nice, but quite basic.
