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

C-
  • Resolution is limited, masking finer nuances and narrowing the soundstage. Busy mixes still overwhelm it with ease.
Bass C+
Low-end delivery feels competent yet unremarkable, keeping a safe profile. Low-end bloom is kept in check.
Mids C+
It presents a stable midrange foundation suitable for everyday listening. Clarity is serviceable without standing out.
Treble D
Expect treble that alternates between muted and splashy in the same track. Cymbals sound inconsistent across tracks.
Dynamics C-
Dynamics are average—competent yet lacking real excitement. It keeps music listenable but uninspiring.
Details C+
Ambient cues appear, albeit with softer focus than die-hard resolution seekers may prefer. You can follow supporting instruments well.
Imaging C-
Separation is good enough for casual listening yet misses audiophile precision. Depth remains limited but present.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

EarAcoustic Audio x Zkaaai Scorings

Average Technical & Tuning Grades

Average Tunign Grade

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

Average Technical Grade

E+
  • Instrument separation collapses instantly, burying nuances and leaving everything in a gray blur. Layered arrangements collapse into a messy haze.
Mids E-
Critical mid frequencies hide in the background, making lyrics hard to catch. Guitars and pianos lose their presence.
Treble E+
Expect a dark-tilted treble that keeps excitement in check. Sibilants are dull, but so is everything else.
Dynamics E+
It struggles to convey small volume changes, flattening energetic bursts. Micro-contrast is practically absent.
Soundstage E-
Spatial boundaries clamp shut, forcing the mix to huddle uncomfortably in the middle. Ambient cues disappear entirely.
Gaming E
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
