The CM-311 offers the best of both worlds: Differoid performance in a comfortable headworn microphone. Designed for touring and live-sound applications it sounds like the best handheld microphones-full, clear, and distortion-free, even with the loudest singers.

Differoid stands for differential cardioid it is a noisecancelling mic, which cancels sounds beyond a few inches away - such as floor monitors, instruments on stage, and crowd noise. Controlled field tests showed that the Differoid provides up to 12 dB more gain before feedback than conventional cardioid microphones. This results in the CM-311 having outstanding gain-before-feedback and isolation. Many users of the Differoid say that their house mix is better because the mic's isolation is nearly complete.

Lightweight and comfortable, the mic's headband and boom adjust to fit any singer.
