At only 1/10; in diameter, Countryman’s B6 is the smallest lavalier in the world, and outperforms microphones many times its size. It features changeable protective caps that provide moisture resistance and color options, along with letting you shape the frequency response to suit different situations or to match other microphones. With its remarkably low handling noise and rugged construction, the B6 is the ideal choice for theater, broadcast, churches, and general lavalier applications. This particular model is designed for use with Sennheiser Digital Transmitters (sold separately-see ;Compatibility; information below).
