BP892x OVERVIEW COPY 
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. Engineered to stand up to the rigors of day-to-day 
use, the BP892x includes a detachable, field-replaceable cable with a robust connector at the 
earset and a variety of available output terminations.
