The BP899 is a low-profile lavalier omnidirectional condenser with terminations for wired or wireless use. The microphone's wide dynamic range and tolerance for high sound pressure levels ensures intelligible, natural-sounding audio that's ideal for use by stage and television talent, lecturers, and worship leaders. Low-sensitivity models are also available for theater use. The diaphragm opening is covered by an acoustically transparent, moisture-repellent protective mesh that delivers maximum frequency response and lasting performance.

An included resonance cap can be applied to the microphone to provide even greater intelligibility, and it is designed to direct sweat and other moisture away from the microphone. The two included windscreens each feature a clasp that secures the windscreen to the mic and prevents it from accidently falling off, which can be critical during active use of the microphone for performances or sports. If up-close, directional miking is needed, the BP898 with cardioid capsule is recommended.

The mic's cable is made of a robust urethane elastomer that provides ultimate flexibility and strength, while resisting abrasion and moisture. The mic comes with a clothing clip that features two strain-relief points that isolate the mic from mechanical noise transferred over the cable.
