Audio-Technica's innovative BP894cT4 MicroSet offers the ultimate in low-profile, high-performance audio. The BP894cT4 features a rotating capsule housing with talk-side indicator for use on either ear and perfect polar pattern placement. The MicroSet BP894cT4 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 BP894cT4 hooks securely behind either ear and can be worn for hours without fatigue. For maximum stability and comfort, the included AT8464 dual-ear microphone mount converts the MicroSet to a dual-ear-worn unit.
Wireless microphone devices operating in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier the that date if their operations could cause harmful interference to a 600 MHz service licensee's wireless operations on these frequencies. For more information, visit the FCC's wireless microphone website at or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
