This is a Deity Connect two channel diversity wireless audio kit. It's a great kit for interviews or any walk and talk situation where your talent might be moving around. I've used this kit in many situations and have never had interference or connectivity issues due to some magic wifi hopping things that Deity does.

The transmiters are small and can be mounted with the included lavs on talent or hidden with mics anywhere. The transmiters accept any 3.5mm microphone.

The receiver is still quite compact, and can be mounted on a camera, strapped to a tripod leg, or placed in an audio bag. You can run the audio into a recorder or camera via XLR or 3.5mm cable.
