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.

Mids are slightly cooked, but it's nice overall. Jaytiss Youtube Channel
A bassy all-rounder, and cleaner Doscinco for $100 less. Very versatile with the different nozzles - goes from bassy to clean all-rounder. Solid packaging and accesories. Competitive tech, but not as value like Supermix4/EM6L/EA500LM. Jays Audio Youtube Channel

2025-07-31An engaging sound signature with good bass and natural mids. Deep bass with strong impact, natural mids with good timbre, and smooth treble with great detail. Lower treble can get a bit energetic, and upper treble lacks some air.Gizaudio Axel original ranking

The KEFINE Quatio impresses with its premium build quality and versatile tuning options. Its lightweight aluminum alloy shells offer both durability and comfort, while the included modular cable with 3.5mm/4.4mm terminations provides flexibility for various sources . The standout feature is the three interchangeable nozzles: gold for a bright, detailed signature, silver for balanced neutrality, and black for a warm, smooth presentation - allowing users to tailor the sound to their preferences .
Sonically, the hybrid 2DD+2BA configuration delivers punchy bass and textured mids across all tunings, with the gold nozzles particularly enhancing vocal clarity and treble energy . While bass enthusiasts might desire more impact, the overall coherence and natural timbre are exceptional for the price point. The technical performance shines through articulate imaging and a spacious soundstage, though some critical listeners may note slight treble roll-off on the black/silver nozzles .
At $129, the Quatio offers remarkable value with its triple-tuning system and comprehensive accessory package including multiple ear tips and a premium case . It stands as a compelling choice for those seeking adaptable sound signatures without compromising on build or technical prowess.
