Unlike earsets that are hard-wired from the mic to the connector, Countryman's cables quickly and securely snap into the E6 Earset to link the mic to hardwired or wireless systems. E6 cables and E2 cables are not interchangeable. The Countryman E6 Earset microphone is a nearly invisible, world-class vocal microphone that delivers high-quality voice pickup, while rejecting surrounding noise and feedback. An ultra-miniature electret condenser element is held close to the mouth by a thin boom and comfortable earpiece. Available in omnidirectional and pattern-adjustable directional versions, the E6 Earset weighs less than one-tenth ounce and virtually disappears against the skin, so performers forget they're even wearing a mic.
