The Westone Audio MACH 30 is a universal-fit in-ear monitor with three proprietary balanced-armature drivers per side (low, mid and high) and a 3-way passive crossover, rated 110dB @ 1kHz and 91Ω, on a detachable Linum BaX T2 cable. It suits vocalists, guitarists, keyboard players and engineers who want what Westone calls a mid-forward, energetic sound.

Who the Westone Audio MACH 30 is for

Vocalists, guitarists and keyboard players: Westone Audio recommends the MACH 30 for vocalists, guitarists, keyboard players, engineers and horn sections.
Hearing each part of the mix: A 3-way passive crossover splits the signal between dedicated low, mid and high balanced armatures.
Mid-focused listening: Westone describes the MACH 30 as energetic and balanced, with a subtle bass lift and clear, bright mids.
Gigging and travel: The silver-plated copper BaX cable detaches at T2 sockets, and a crushproof, watertight mini monitor vault plus 5 pairs each of foam and silicone tips come in the box.
Skip it if: you want heavy, deep bass; Westone gives the MACH 30 only a subtle bass lift, and it is rated 20Hz–18kHz, narrower than the 5Hz–22kHz MACH 70 and MACH 80.
