Audio-Technica BP894xcH Subminiature Cardioid Condenser Headworn Microphone with Locking 4-pin Connector

Unobtrusive • Lightweight • Outstanding sound quality.

Combining innovation, high-SPL (sound pressure level) handling and a low profile, the Audio-technica BP894xcH package features the BP894x MicroSet® microphone which hooks behind either ear for a secure, comfortable fit. In addition to delivering high-performance audio that's clear and accurate, it features a rotating capsule housing with talk-side indicator for ideal polar-pattern placement. The mic is a subminiature cardioid condenser model that delivers a flat, extended frequency response which results in extremely intelligible, natural audio. It includes a detachable, field-replaceable cable with a robust connector at the earset and terminated at the other end with a screw-down 4-pin connector for use with Audio-Technica cH-style wireless body-pack transmitters (sold separately). It comes in your choice of either black or beige ("theater" color).
