An 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

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

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.
