Why you need the Crown CM311AESH Headset Microphone

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.
