Sanken COS-11D Omni Lavalier Microphone, Phantom/Battery Power & XLR Connector (Black)

Sanken COS-11D Omni Lavalier Microphone, Phantom/Battery Power & XLR Connector (Black) is designed for professional audio applications in broadcast, television, theatre, film, and video production. Its ultra-compact subminiature form factor allows it to be discreetly hidden in clothing or costumes, while delivering crystal-clear, natural sound and dependable performance in any recording environment.

Engineered with advanced RF shielding, the COS-11D eliminates unwanted interference for a clean audio signal. Its unique rectangular, vertical diaphragm design increases the capsule’s surface area, producing rich, full-bodied sound quality that outperforms many larger lavalier microphones. With a wide 50 Hz to 20 kHz frequency response, it naturally rolls off extreme low frequencies and offers a subtle presence boost at 6 kHz, ensuring clear and intelligible speech.

The microphone’s omnidirectional polar pattern captures sound evenly from all directions, maintaining consistent audio levels even when the speaker turns away. This makes it an excellent choice for presenters, actors, and on-camera talent who require reliable audio pickup without restrictive positioning.

Designed for challenging environments, the COS-11D features a water-resistant mesh screen to protect against humidity, perspiration, makeup, and unpredictable weather conditions. The robust, moisture-resistant cable remains soft and pliable even after extended use, ensuring long-term durability for both indoor and outdoor productions.
