The Audio-Technica AT829CW is a miniature cardioid condenser lavalier microphone purpose-built for professional wireless applications in theater, broadcast, corporate presentations, and live event production. The permanently attached 55" cable terminates in a locking 4-pin connector compatible with Audio-Technica cW-style body-pack wireless transmitters, eliminating cable compatibility issues and ensuring secure connection during performance or presentation. Its cardioid polar pattern rejects off-axis ambient noise and feedback while maintaining excellent proximity to the speaker's voice, making it ideal for actor reinforcement, presenter audio, and interview capture in field production.

The 24mm long, 10.5mm diameter form factor allows discreet mounting on clothing without drawing visual attention, while the condenser element delivers clean, accurate voice reproduction with natural presence. Included foam windscreen and clothing clip provide immediate deployment without additional accessories. Suitable for rental companies, theater sound departments, broadcast facilities, and mobile production teams requiring reliable lavalier performance with the security of locking wireless connectivity.
