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.
