Product Code: CM311AESH

Designed for touring and live-sound applications, the Crown® CM-311AESH is a rugged head-worn microphone with unequalled 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 the 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.

Package includes a mic carrying case, WS-6 foam pop filter, and clothing clip.
