The black SCM0001 from DPA is a flexible clip that is
designed for mounting a d:screet Heavy-Duty Miniature Microphone (sold
separately) on the chest of a speaker or performer. It can be used to provide a
stable mounting of the microphone, even on thin clothing. In addition, the
rubber piece inside the clip is for holding a short cable loop, which will
increase the system's immunity to cable noise.
