Audionotions 3 Reviewer Score
Sound stage and imaging are good. Very, very bright/sibilant set though. Would be good for gaming and maybe trebleheads but I found it way too hot to listen to at length - actually caused a headache. Very small and light IEMs but for my ears fit was tricky. Had to tip roll to get it to seal.

Final A4000 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

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

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-
It delivers a workable midrange that could benefit from smoother transitions. Timbre isn't quite convincing yet.
Treble E+
Expect a dark-tilted treble that keeps excitement in check. Sibilants are dull, but so is everything else.
Dynamics D
Dynamics come across throttled, leaving energetic moments underwhelming. Energetic passages land with a thud.
Soundstage C+
It pushes sound outward confidently while leaving height development as an unfinished idea. Height remains subtle but detectable.
Gaming D-
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
