The SHURE's SM10A-CN is a low-impedance, unidirectional dynamic microphone that designed for that is ideal for close-talk head-worn applications like remote sports broadcasting and business intercom systems. It's also suitable for singers, keyboardists, and other performers who require a head-worn vocal microphone with excellent noise rejection and a smooth, natural-sounding frequency response. Wind noise and explosive breath sounds are reduced by using the provided windscreen.
