Sanken, manufacturer of the industrywide standard in ultra-miniature lavalier microphones, now offers the COS-11x. This new generation lavalier was designed to meet today's HD audio standards while satisfying the concealment requirements of film, video and theater. The COS-11x features a new front mesh screen which is water resistant, better protecting the microphone from perspiration and cosmetics. As a result, the COS-11x maintains superb frequency response in adverse recording conditions. In addition, the water resistant COS-11x is ideal for outdoor shooting in foul weather.

Sanken utilises an original vertical placement of the diaphragm for a much greater effective area within an extremely small casing. Sanken's unique and innovative designs have been emulated by other microphone manufacturers, but never matched in quality and performance.
