Boya Pro Digital Camera-Mount Wireless Omni Lavalier Microphone System (2.4 GHz) BY-WM4

A 3.5mm TRS cable for connection to a camera or camcorder is included. The compact receiver features a removable attachment clip that comes off to accommodate the included shoe mount for placement on your camera. For a two-person shoot, simply add another transmitter instead of buying a whole system. Since the RX4 Pro is a dual-channel receiver, it can simultaneously handle two TX4 Pro wireless transmitters (second transmitter available separately).
