AudioTechnica ATM75CH Cardioid Condenser Headworn Microphone

Audio-Technica's ATM75cH represents a purpose-built solution for performers and presenters requiring reliable hands-free vocal capture. The cardioid condenser element employs a fixed-charge back plate design, delivering professional-grade pickup across a 100–13,000 Hz range. Its flexible boom arm pivots left or right, accommodating individual comfort preferences whilst maintaining consistent proximity to the sound source.

The ATM75cH terminates in a screw-down 4-pin connector sized for Audio-Technica cH-series body-pack transmitters, with a 1.4 m permanently attached miniature cable. Operating on phantom power (11–52 V DC), the capsule achieves 132 dB SPL at 1% THD and a 96 dB dynamic range, whilst the cardioid polar pattern actively rejects off-axis sound. Weighing just 60 g, the microphone head pairs with an optional 139 g power module for battery operation (2000 hours typical on alkaline). Package includes dual windscreens (large and small) and a clothing clip for secure cable routing.

The low-visibility headband design prioritises comfort during extended wear, critical for touring musicians and event professionals. Frequency roll-off at 80 Hz (18 dB/octave) with wired operation reduces low-end rumble and handling noise, refining vocal clarity in live and rehearsal environments.
