The beige Nady HM-20U HEADMIC Series Headworn Condenser Microphone is intended for hands-free microphone applications during presentations, performances, fitness instruction and more. The low-profile microphone features a thin, form fitting ergonomic frame. The miniature capsule features a wide frequency response and cardioid polar pattern that maximizes feedback rejection. The HM-20U has a locking 3.5mm connection intended for use with Nady transmitters, however a standard XLR adapter will allow for use with standard microphone preamps.
