WBK501 Wireless Lavalier Microphone Kit

A clip-on microphone and its receiver, for getting a voice off the camera and onto the speaker. Phone microphones pick up the room; a lavalier on a collar picks up the person, which is the whole difference between watchable video and not.

The transmitter clips to a shirt and the receiver plugs into the phone or camera. No cable running between them, so an interview subject can move.
