Overview
Planar magnetic IEM with a 14.2 mm thin-film diaphragm — the largest planar driver size that still fits a universal IEM shell. The diaphragm sits between two magnet arrays in an open-vented chamber, producing piston-uniform motion with extraordinarily low THD (0.1 % at full listening level).
Drive requirement is higher than typical IEMs: 32 Ω impedance with 98 dB/mW sensitivity, recommended amp power around 80 mW. Marginal on a phone-dongle DAC; properly served by a balanced DAP or a desktop integrated.
Detachable via 0.78 mm 2-pin. The tonality leans neutral with a slight warm cast and excellent low-frequency extension. Tonal context: IEM driver types explained.
