Audio-Technica’s high-SPL BP892x MicroSet® offers the ultimate in low-profile, high-performance audio. Delivering clear and accurate sound in an inconspicuous package, the ultra-lightweight BP892x hooks securely behind either ear and can be worn for hours without fatigue. For maximum stability and comfort, the included AT8464x dual-ear adapter kit converts the MicroSet to a dual-ear-worn unit.

The BP892x MicroSet’s subminiature omnidirectional condenser capsule delivers extremely intelligible, natural audio with a flat, extended frequency response that is ideal for stage and television talent, lecturers, and worship leaders.
