QoA × Eir Aoi — first artist deep-custom universal IEM. Exclusive tuning, hand-drawn artwork, and a sound palette inspired by a signature cocktail.
Co-branded with Eir Aoi, MistyBlue seals indigo quicksand beneath a crystalline shell—flowing grains on the panel symbolize the river of time, while the deep blue evokes the boundless sky. Each earbud features hand-drawn art by the QoA team, turning the IEM into Eir Aoi’s personal “blue sky and mist”.
MistyBlue blends mixology and acoustics: treble extends like citrus oils in Blue Curaçao; mids are juicy and resolving like pineapple and lemon; white rum lends a warm low-frequency wrap; a touch of vodka gives icy sub-bass reach. Notes layer like a cocktail—clear, bright melodies unfolding in a misty soundstage.
10 mm PET (6 μm) Dynamic — Bass
Ultra-thin PET diaphragm with instant rebound and special voice-coil structure for elastic, deep bass and clean impact. Innovative suspension promotes uniform low-frequency diffusion and stable layering.
QoA Custom BA — Mid/High
Fast transients and crystalline tone for metal timbre, strings and upper-harmonic overtones.
8 mm PET Titanium-Plated Dynamic — Midrange
Titanium coating boosts rigidity while PET keeps flexibility—silky vocals, accurate breath/throat detail, articulate piano and guitar attacks without harshness.
Knowles Custom BA — High & Super-High
Metal-diaphragm clarity with natural air; precisely controlled sibilance for graceful extension.
