A wireless lavalier microphone functions similarly to a standard microphone in that it relies on an acoustic signal to pick up sound. However, instead of relying on a cable to transmit the audio, a wireless transmitter encircles the lavalier microphone and sends the audio feed wirelessly to a receiver. This receiver can be mounted on a production desk or handheld device for easy access. The quality of a wireless lavalier microphone will largely depend on the quality of its transmitter and receiver.
