TheElectro-Voice HM2 headworn microphoneis the ideal microphone for anyone who requires high-quality vocals in a hands-free application. The HM2 is perfect for use by lead vocalists, singing instrumentalists, dancers, aerobic instructors and other presenters.

The HM2 has a miniature electret condenser element designed with a cardioid polar pattern, which attenuates background noises such as sound from nearby floor monitors, on-stage musical instruments and crowd noise. The furnished open-pore windscreen slips over the microphone element to reduce wind noise and minimize P-popping the excessive explosive breath noise caused by overemphasized p and t sounds.

The Electro-Voice HM2 headworn microphone employs a comfortable and inconspicuous behind-the-head headband and flexible boom arm in an attractive Nonreflective black matte finish. The flexible boom, which descends from the right of the headband, is enclosed with protective shrink tubing to shield the boom arm from deterioration and to prevent the flexible tube from catching on facial hair. The facial features of the performer or speaker will not be obstructed due to the HM2s unobtrusive design. The headband and microphone boom adjust to fit any performer or speaker.

The HM2 is designed to have a frequency response similar to a handheld vocal microphone. The HM2 headset exhibits bass- boost (proximity-effect) warmth that many vocalists prefer. The amount of proximity effect can be adjusted by moving the microphone element closer or farther away from the mouth. The HM2 is permanently connected to a 1.2-m (4 ft) shielded cable terminated with a miniature Switchcraft TA3F connector.
