Sanken COS-11D Overview

The black Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and Non-Servo TA5F Connector for Lectrosonics Transmitters is a subminiature lav microphone designed to deliver clear, full-bodied sound and reliable performance, making it a popular choice among industry professionals in broadcast, TV, theater, film, videography, and more. 

Engineered to meet the standards of modern digital wireless microphone systems, the COS-11D is RF shielded to eliminate interference issues and ensure a pristine audio signal. The microphone capsule features a rectangular design that sits vertically, increasing the surface area and allowing this tiny mic to offer a rich, full sound that outperforms many larger models.

The mic's 50 Hz to 20 kHz frequency response rolls-off extreme low end and provides accurate, transparent audio reproduction with a small presence boost in the 6 kHz area for crisp, intelligible speech. With a forgiving omnidirectional polar pattern that picks up sound in a 360° pattern, levels stay consistent, even when the subject turns away from the mic.

A water-resistant mesh screen protects against humidity, perspiration, makeup, bad weather, and other potential on-location issues, while the durable cable is also moisture-resistant and built to stay soft and pliable, even after extended use. This version of the COS-11D terminates in a TA5F connector and is wired for use with non-servo-bias Lectrosonics transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Non-Servo TA5F Connector
Compatible Wireless Transmitters
  • Lectrosonics: Works with Lectrosonics bodypack transmitters equipped with a non-servo TA5M connector including the UM200 and UM400 models.
  • Also works with third-party wireless transmitters that are equipped to supply 3 to 10 VDC through a TA5M connector wired for non-servo-bias Lectrosonics compatibility.
Broadcast-Quality Sound and Dependable Performance
Subminiature Mic with a Big Sound
The camera-ready COS-11D features a subminiature capsule that enables the microphone to be inconspicuous and easily disguised in clothing or costumes. The unique vertical diaphragm design offers a clear and natural sound optimized for the human voice.
Normal Headroom for Standard Speech
This version of the mic features a normal sensitivity setting for standard speech levels up to 123 dB SPL.
Omnidirectional Polar Pattern
The forgiving omnidirectional polar pattern picks up sound from all around the mic and provides a consistent frequency response, even for off-axis sound. This helps to supply clear, intelligible speech and vocals, even when the talent isn't speaking directly toward the microphone.
Tough, Water-Resistant Construction for Indoor/Outdoor Locations
The water-resistant front mesh screen provides reliable protection from perspiration and moisture, making the mic a solid performer in all kinds of weather. The rugged cable is also built to resist moisture and handling noise and stay pliable, even after repeated uses.

Sanken COS-11D Reviews

Discrete with natural sound

By Kurt

I purchased this on recommendation from a singer for a performance. After a relatively quick EQ and set up, we used it for the performance. The sound was very natural, better than my previous encounters with lav mics for sure. Admittedly, I don't use many lavs in my work, but this one seemed particularly good.

The Industry Standard

I found my way to these microphones after years of working with stock lavs that came with my wireless systems, I even upgraded to another pro lav mic that eventually fell apart, but the Sanken has held up for years, it's small, easy to conceal, has great sound and build quality. I have one in black and one in gray so I can tell them apart at a glance.
