BZBGear BG-MIC-U1 USB Boundary Conference Microphone
The BG-MIC-U1 is a plug and play USB conference microphone with a back electret cardioid condenser capsule and an internal shock mount that keeps table knocks out of the signal. A dual colour LED shows green when the mic is off and red when it is live, and a membrane switch mutes it.
It connects with a single USB Type B to Type A cable and needs no driver, and the built-in mounting holes mean it can be fixed to a wall or ceiling rather than left loose on a table. Frequency response is 30 Hz to 12 kHz, maximum SPL is 125 dB at 1 percent THD, and conversion runs to 48 kHz at 16-bit.
