BINARY – EP321 MEMS 2DD + 3BA + 1 MEMS Tribrid Drivers In Ear Monitor
The Binary EP321 MEMS sets a new benchmark in tribrid IEMs with its innovative 2DD + 3BA + 1MEMS driver array. Dual Dynamic Drivers (10mm primary + 6mm passive radiator) produce deep and textured sub-bass rumble. Three Balanced Armatures deliver transparent mids and natural vocals, and the world's first direct-drive MEMS driver achieves electrostatic-like treble extension to 40kHz with under 1% THD for shimmering airiness and micro-detail. This IEM reproduces a well-balanced and detailed presentation overall. It offers a W-shaped tuning with quality bass, forward mids and sparkling highs. The 1.2m 8-strand silver-plated copper modular cable ensures low microphonics and pure signal transfer, while 3D-printed resin shells with CNC stainless steel faceplates provide top-notch passive isolation. The shells feel lightweight and provide ergonomic fit for all day comfort. Strategic venting increases comfort by decreasing pressure buildup during workouts or casual home sessions.
