The Invisible Mic Cold Shoe from Insta360 is a small bracket designed to hold the RODE Wireless GO clip-on mic receiver on the side of the ONE X2, X3, or X4 camera and keep it out of view of the camera lens. It's designed to sandwich in between the camera and a selfie stick without any screws or other hardware required.
Simply place it on the bottom of the camera, right under the 1/4"-20 threaded mounting hole, and then screw in your selfie stick, mini tripod, or other support. The GO mic receiver can then easily be clipped on and off the bracket. The included short 3.5mm audio cable connects the mic receiver to the camera.
