High-clarity, potentially fatiguing sound with surprisingly good bass and treble extension.

Insane value. Still a bassy KZ, but for 15$, hard not to rec. Punches at higher price bracket, but still has 4.5k and 8k peaks for my library. I recomend EQing it - turns it into a beast for the price.

CCA CRA Scorings

Average Technical & Tuning Grades

Average Tunign Grade

C-
  • Uneven emphasis across the spectrum keeps the presentation unsettled and awkward. Acoustic instruments lose their natural body.

Average Technical Grade

C-
  • Even moderate complexity exposes the limited resolution and narrow sense of space. Technical fans will find it lacking.
Bass B-
It delivers adequate punch and texture, though nothing stands out. Sub-bass presence is hinted rather than delivered.
Mids C
Midrange is passable yet unrefined, revealing grain and occasional harshness. It sounds a bit grainy on detailed recordings.
Treble C
The top end sounds acceptable but lacks the smoothness of higher tiers. Air is hinted at more than delivered.
Dynamics C+
You get reliable macrodynamics, with micro shifts that remain only adequate. A reliable performer for most tracks.
Details D+
Textural clues dull down, robbing strings and vocals of their natural grit. You hear outlines rather than textures.
Imaging D
Modest imaging with basic left/right positioning that never quite nails the center image. Left/right cues exist but are rough.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

Gaming B-
Moderate spatial presentation conveys general directionality. Suitable for casual play where precision isn't critical.
