Westone Audio Mach 20 Universal IEM — Dual Balanced-Armature Musicians' In-Ear Monitors with Linum® Estron BaX™ T2 Cable

Built for professional musicians, the Mach 20 delivers a robust, punchy low end and a detailed soundstage that translates well on stage or in casual listening. Its dual balanced-armature configuration uses one dedicated low driver and one mid/high driver to reproduce a clear, accurate audio picture. The earphones ship with the Linum® Estron BaX™ T2 — a true high-end reference cable constructed from very thin, ultra-strong silver plated copper for reliable signal transfer and durability. Ergonomically shaped housings minimize ear fatigue for comfortable, all-day wear. Technical specifications: Frequency Response: 20Hz - 18kHz; Sensitivity: 110dB @ 1kHz; Impedance: 96 Ohms @ 1kHz.
