AKG N400 Reviews
Does away with the timbral issues of the Buds+ and sets itself as a superior. Crin Youtube Channel
Bass is good. Lacks some note weight, mids could be more foward and gets shouty easily. Fit is an issue to me so I can't really use it. You can play with APP EQ to fine tune it, but the worst APP of the bunch.

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.
