Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & 3.5mm Locking Sennheiser Connector (with Accessories, Black)

The Sanken COS-11D Omni Lavalier Microphone (Black) with locking 3.5mm Sennheiser connector is a professional-grade subminiature lav mic trusted worldwide in broadcast, film, television, theatre, and videography. Renowned for its natural tone, reliability, and discreet size, the COS-11D delivers exceptional vocal clarity in demanding production environments.

Designed to meet the requirements of modern digital wireless microphone systems, the COS-11D features advanced RF shielding to minimise interference and maintain a clean, stable signal. Its unique vertically oriented rectangular capsule increases surface area, allowing this compact microphone to produce a rich, full-bodied sound that rivals much larger lavaliers.

• Professional omnidirectional lavalier microphone in black finish
• Normal sensitivity for standard speech (up to 123 dB SPL)
• Locking 3.5mm connector wired for Sennheiser compatibility
• RF shielded for reliable use with digital wireless systems
• Water- and moisture-resistant construction for indoor/outdoor production

The COS-11D offers a 50 Hz to 20 kHz frequency response, tuned to roll off excessive low frequencies while maintaining accurate, transparent reproduction. A subtle presence boost around 6 kHz enhances speech intelligibility, helping dialogue sound clear and articulate in real-world recording conditions.

With its omnidirectional polar pattern, the microphone captures sound evenly from all directions, ensuring consistent levels even when the talent turns their head or moves naturally during performance.

Built for real-world production environments, the COS-11D includes a water-resistant front mesh to protect against sweat, humidity, makeup, and light moisture, plus a rugged, moisture-resistant cable that remains soft and flexible even after extended use. These features make it a dependable choice for both indoor and outdoor recording.

This model terminates in a locking 3.5mm connector wired for Sennheiser, making it compatible with Sennheiser bodypack transmitters equipped with a locking 3.5mm connector, including the Evolution (ew), XSW-D, and SpeechLine (SL) series. It can also work with many third-party wireless transmitters and portable recorders supplying 3 to 10 VDC via a locking 3.5mm input wired for Sennheiser compatibility.

The COS-11D’s subminiature, camera-ready capsule is easy to conceal in clothing or costumes, making it ideal for on-camera talent. Its discreet size combined with professional sound quality makes it a favourite among sound mixers and broadcast professionals worldwide.
