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 ZS12 PRO 2 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

C+
  • Expect a friendly tonal balance that could use polish but remains inviting. Great for casual listening, less so for purists.

Average Technical Grade

C+
  • Technical ability is serviceable, keeping basic detail intact across simpler tracks. It keeps up with acoustic tracks without much fuss.
Mids C+
Midrange performance is decent, offering balanced presence without major flaws. It works well for casual background listening.
Treble C+
Expect a polite treble presentation that balances presence with restraint. Percussion carries a pleasant sparkle.
Dynamics C+
Dynamics feel competent, bringing energy without the finest detail. It carries energy without sounding aggressive.
Soundstage B
Lateral spread stretches comfortably while front/back cues start to feel convincing. You can trace front-to-back movement.
Gaming C+
Fundamental left/right positioning with limited depth perception. Works for non-competitive gaming but lacks precision.
