Audio Technica AT831b Miniature cardioid condenser microphone

This clip-on lavalier mic provides crisp, full-sounding voice pickup and excels as an instrument mic, especially for pickup of acoustic guitar with included AT8444 guitar adapter. It offers excellent gain before feedback and suppression of background noise. An integral 80 Hz high-pass filter provides easy switching from a flat frequency response to a low-end roll-off. It operates on battery or phantom power.
