The ME 3 Headmic from Sennheiser is a headworn electret-condenser microphone well suited for use with wireless systems in presentation, vocal, and broadcast work for live stage, television, boardrooms, houses of worship, and more.
 
The ME 3 offers a frequency response from 50 Hz to 18 kHz for clear, intelligible speech and vocals, and it can handle loud speech and vocals up to 150 dB without distorting. The microphone's cardioid polar pattern picks up less background noise and focuses audio capture on the speaker, helping to reduce feedback problems, especially when used with loudspeakers and sound reinforcement equipment.
