The MKE 1 - Sennheiser's smallest clip-on microphone - performs at its best in all situations where a microphone needs to be virtually invisible and still offer outstanding sound quality. Sweat protected by a newly developed protective membrane, the MKE 1 stands up better than other clip-on microphones to harsh live conditions. Its special gauze and multi-purpose cap offer additional protection from moisture so that it only picks up what it is meant to pick up - perfect sound.
