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 ZAS Scorings

Average Technical & Tuning Grades

Average Tunign Grade

D-
  • Expect a discordant presentation where frequency clashes ruin any chance of relaxed listening. It struggles to render a cohesive musical picture.

Average Technical Grade

D
  • Details smear quickly, leaving the presentation cramped and low on definition. You'll notice smearing on even moderately layered songs.
Bass D
Bass remains light-handed, hinting at rumble without delivering real weight. It keeps out of the way but never excites.
Mids D
The region feels unstable, alternating between honky resonance and missing information. You'll hear odd resonances across the mids.
Treble E+
Expect a dark-tilted treble that keeps excitement in check. Sibilants are dull, but so is everything else.
Dynamics D
Dynamics sound noticeably compressed, muting contrast between quiet and loud. Transients feel blunted and slow.
Details D
Modest detail presentation that sacrifices texture and masks subtle nuances. It conveys the basics but not the nuance.
Imaging D
Modest imaging with basic left/right positioning that never quite nails the center image. Left/right cues exist but are rough.
Gaming D-
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
