Headworn microphones, whether on one ear – earset – or two ears – headset, are popular because of their ease of use, amazing sound and flexibility. Once placed on the performer, the headset microphone sits securely and unobtrusively close to the sound source and allows the user to move freely about without having to hold a microphone in the hand or have a lavalier mic clipped on the shirt. Headset mics remove the disadvantage of changing color of the sound as the head moves around.
