Model: COS11D-EW-RD-BEI | Red Dot Version
Broadcast-Grade Lavalier Microphone for Live, Location & Studio Recording

The Sanken COS-11D Red Dot is particularly well suited to high-output speakers, presenters and performers, where controlled sensitivity and clean dialogue capture are essential. COS11D Red Dot version for SPL up to 132dB (9db SPL lower sensitivity than the normal  version.)

The Sanken COS-11D Lapel Microphone continues the long-standing COS-11 tradition of delivering exceptional audio quality for live broadcasting, location recording and studio applications. Widely regarded as an industry standard, the COS-11D is trusted by professional sound mixers for its natural vocal reproduction, durability and consistent performance in challenging conditions.
This version is supplied with a connector to suit Sennheiser Evolution Wireless (EW) systems, finished in beige for discreet on-camera use, and features the Red Dot (low-sensitivity) capsule, making it ideal for high-SPL environments.

Advanced Design for Real-World Production Conditions

The COS-11D introduces a water-resistant front mesh screen, providing enhanced protection against perspiration, cosmetics and moisture. This design helps the microphone maintain its superb frequency response, even in adverse recording conditions such as hot sets, concealed wardrobe placement, or outdoor shoots in foul weather.
As a result, the COS-11D is especially well-suited to demanding location work, reality TV, live broadcast and long-form production, where reliability is critical.
