Designed for touring and live-sound applications, the Crown CM-311AESH is a rugged head-worn microphone with unequaled performance. It sounds like the best handheld microphones ” full, clear, and distortion-free, even with the loudest singers.

The CM-311AESH is the latest version of Crown's proprietary Differoid technology. Its cardioid pickup pattern rejects sounds from the rear, such as floor monitors. Its noise-canceling ability rejects sounds at a distance, such as instruments on stage and crowd noise. This results in the CM-311AESH having outstanding gain-before-feedback and isolation.

Lightweight and comfortable, the mic's headband and boom adjust to fit any singer. An included pop filter greatly reduces breath noise and pops. Because of the boom's unique behind-the-ear design, it does not cover up the singer's face.

NOTE: Putting an XLR connector on the CM-311AESH and connecting to a mic input with phantom power WILL damage the mic element.

Consumer Alert:

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change.
