The beige Sanken COS-11D Omni Lavalier Mic for Lectrosonics Transmittersfor 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 the 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 3-pin LEMO connector and is wired for use with Lectrosonics transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Related Questions and Answers

Q: 1. will this work with a regular recorder like the Roland R05?

A: This model of the Sanken COS11D is wired specifically for use with the Sony UWP wireless system, transmitters. it is likely it will produce audio when connected to the Roland R05, however the locking connector prevents the mic jack from being properly seated. This would not be recommended for use other than intended. Sanken does not currently offer a model compatible with portable audio recorders. There are several mics that are designed for portable recorders and offer similar quality such as the Tram TR50 see B&H# TRTR50BNLSET or Countryman EMW. B&H # COMEMWSFF05B.

Q: 2. Are these locking 3.5mm / ⅛in connections compatible with the Saramonic uwmic9? The wireless receiver has a bit of a lip around the outlet…

A: Unfortunately they are not. Sanken makes the COS-11D for many wireless systems. If you don't see the name of your system listed. Then it is not made for you're system. All 3.5mm connectors are not wired the same. Because it's made for Sennheiser doesn't mean it's wired for your 3.5mm system.

A: The Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & 3.5mm Locking Sennheiser Connector should work well with Sennheiser transmitter products featuring a 3.5mm locking input connection. We are not aware of any common issues in this scenario and would suspect that perhaps the specific lavalier cable or transmitter input in the described scenario may have become intermittent with use over time.
