Weird upper trebble is killing it for me, but it might be good for you.

Best KZ Planar IEM. Warm, bassy sound, lacking a little in dynamics. Foam tips come worn down in the package. Shrill tonality in higher treble for some listeners

7hz Sonus 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.
Mids C+
The mids are solid and dependable, though not especially remarkable. Vocals stay reasonably grounded in the mix.
Treble C-
Highs are present enough yet carry a bit of grain and splash. Busy mixes can still feel a bit splashy.
Dynamics E+
Dynamic range feels limited, smearing micro-contrast and transient attack. Soft details are smoothed into the background.
Soundstage B
Good soundstage with proper width and depth, placing instruments in clearly defined positions. Instruments sit in their own lanes.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

KZ PRX Scorings

Average Technical & Tuning Grades

Average Tunign Grade

D+
  • Expect a patchy tonal profile that makes instrumentation feel mismatched. EQ is almost mandatory to tame the response.

Average Technical Grade

E-
  • A foggy, one-dimensional presentation wipes out layering and obscures the finer points of a mix. Spatial cues barely register at all.
Mids C+
Midrange performance is decent, offering balanced presence without major flaws. It works well for casual background listening.
Treble E-
The top end feels muffled, with air and shimmer barely audible. Ambient reverb tails are chopped short.
Dynamics E+
Subtle shifts disappear, with transients lacking bite or urgency. Drum hits arrive without conviction.
Soundstage C+
You start to perceive distinct rows of players even if the ceiling still feels low. Layering is present but still modest.
Gaming E
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
