C-- Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.
Average Technical Grade
C-- Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.

Fiio FH3 Reviews
Bass, but at what cost? Everything. Jaytiss Youtube Channel
Comment: Bass boosted neutral tuning. Narrow soundstage
Does come off as sort of a broken FH5, but the FH5 elements are mostly there. Crin Youtube Channel
My first IEM. Bad coherency and timbre. Good techs, bad tuning for my library. IMO, there are better and cheaper options out there.
Bloated bass and general congestion issues. Precogvision Youtube Channel
Kiwi Ears Airoso Reviews
A sightly more airy/detailed EW300 with better timbre. Warm leaning all rounder with good dynamic contrast. Jays Audio Youtube Channel
Rich thick, enjoyable. Benchmark for me. Just epic. Jaytiss Youtube Channel

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.
