The Sanken COS-11 lavalier microphones, designed with the highest audio standards, use the unique "Vertical Diaphragm Layout" which provides superb sound. The COS-11s has perfect OMNI Directional polar patterns from 20Hz to 20kHz, and very natural sound from 50Hz to 20kHz. The frequency response is consciously adjusted to the human voice.

Additionally, the COS-11 Series of microphones satisfy the concealment requirements of theater and high-resolution film and video. The new COS-11s cabling was developed in conjunction with renowned musical sound design companies responsible for theater systems around the world. Extensively field tested, the resulting COS-11s is extremely rugged and highly impervious to the body humidity associated with rigorous stage, film and TV production. Even after extended usage, cabling remains soft, pliable and adheres comfortably to the skin.

Ideal for live broadcasting, location recording and theater applications, the COS-11s assures top levels of transient response, extended frequency range and extremely low sensitivity to mechanical noise. The COS-11s provides unprecedented omni-directional response.
