The CM311 reference head-worn condenser microphone is 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, which cancels ambient noise from floor monitors, crowds and other sources. Controlled field tests show that the Differoid provides up to 12dB more gain before feedback than conventional cardioid microphones. Many users of CM311 say that their house mix is better because the mic's isolation is nearly complete.

The CM-311A is powered by a 9V battery or phantom power. It has a battery belt pack with an on/off switch, a programmable mic on/off switch, and a "Mic On" LED. The microphone comes with a custom molded hard plastic case.

Differoid noise-cancelling technology
for highest ambient noise rejection

Cardioid polar pattern
for outstanding gain before feedback

Condenser capsule with internal shock mount
for efficient rejection of mechanical and body noise

Robust headband construction
for maximum comfort and freedom of movement


  • Low latency and signal issues, often found in wireless connectivity, are no longer a problem with wired connectivity
  • Capable to throw a crisp and clear audibility with 50 Hz - 17 kHz frequency response
  • Cardioid pattern captures sound from the front and avoid unwanted signals from other sides to ensure noise-free recording
  • Its head worn design provides a comfortable fit
