A sightly more airy/detailed EW300 with better timbre. Warm leaning all rounder with good dynamic contrast.

The Kiwi Ears Airoso offers a warm, smooth sound signature characterized by a full-bodied bass with satisfying sub-bass rumble and quick decay, though mid-bass impact remains reserved. Its midrange shines with a natural and organic presentation, particularly excelling with female vocals, though some male vocals lack weight. Treble is relaxed and non-fatiguing, providing decent air but lacking sparkle and ultimate detail retrieval.

Comfort is a mixed bag; the lightweight resin shells with CNC aluminum/titanium faceplates are praised by some, but others report significant fit challenges due to the shell shape and nozzle design, requiring tip rolling beyond the included selection. The stock cable is widely criticized as basic and low-quality for the price point, though the detachable 2-pin design allows for upgrades. Soundstage is reasonably spacious but not particularly expansive, with imaging being competent rather than exceptional.

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.
