A flexible rubber microphone clip for standard handheld mics, the everyday replacement when the clip that came with your stand has split or lost its grip. Large cup that takes microphones from 20 mm in diameter, and a brass 5/8 inch thread so it screws straight onto most mic stands and boom arms. AMS say it suits most popular microphones; it is the one for wired dynamic vocal mics, while fat wireless handhelds need the HD80. Part number HD30.
