Surprisingly well-tuned for a KZ, but with too much 3-5kHz presence and hoarse timbre.

Average Technical & Tuning Grades

Average Tunign Grade

C-
  • The tuning lacks refinement, jumping between dull and shouty without settling. Vocals frequently sound off-kilter.

Average Technical Grade

D
  • Even moderate complexity exposes the limited resolution and narrow sense of space. Technical fans will find it lacking.
Bass C-
Bass stays subdued, content to hover in the background. It keeps things tidy, yet unremarkable.
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 is tidy and serviceable, adding air without overdoing it. Extension is decent for casual listening.
Dynamics D
Dynamics sound noticeably compressed, muting contrast between quiet and loud. Transients feel blunted and slow.
Details C-
The presentation is fine for casual listening but leaves refinement on the table. There's some grain on quieter elements.
Imaging D
Panning effects blur at the edges, making movement sound smeared. Fast panning effects smear noticeably.
Gaming D+
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
