COS-11D Lavalier Microphone

The COS-11D is an ultra-miniature omni-directional lavalier microphone, widely used in film, television, theater, and broadcast. It is available in two versions: the COS-11D (48V phantom power) and the COS-11DBP (AA battery or 12–52V phantom power). Both deliver natural, transparent sound with high reliability, even under demanding conditions.

Other versions are also available, such as the COS-11DR (with direct connectors for wireless transmitters) and the COS-11D-HWM (HeadWorn Microphone).
Note: The COS-11D-RM (Red Mark) Series is also available, a 9 dB attenuated low-sensitivity version designed for high SPL applications. Please contact Noyz Boyz Audio for this model.
