Function: It allows you to clip a square-style wireless microphone transmitter onto the top of the handle, converting it into a professional-looking handheld mic for on-camera interviews.
Wind Protection: Most versions include a high-density foam windshield that covers the transmitter. This effectively reduces wind noise and "plosive" sounds for clearer audio in outdoor or busy environments.
Compatibility: These handles are generally universal and compatible with popular wireless systems like RØDE Wireless GO I/II, DJI Mic, Hollyland Lark, Synco, and Movo.
