Audio Technica BP894 Subminiature cardioid condenser headworn microphone

Audio-Technicaʼs innovative BP894 MicroSet® offers the ultimate in low-profile, high-performance audio. The BP894 features a rotating capsule housing with talk-side indicator for use on either ear and perfect polar pattern placement. The MicroSet BP894 takes headworn microphones to the next level, by allowing the cardioid capsule to be aimed directly at the sound source. The uniform pickup pattern provides excellent rejection of outside noise, with exceptional gain-before-feedback when used with live sound systems and stage monitors.

Delivering clear and accurate sound in an inconspicuous package, the ultra-lightweight BP894 hooks securely behind either ear and can be worn for hours witout fatigue. For maximum stability and comfort, the included AT8464 dual-ear microphone mount converts the MicroSet to a dual-ear-worn unit.
