The beige Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and Locking 3.5mm Connector for Sony 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 locking 3.5mm connector and is wired for use with Sony transmitters. Accessories are available separately and are not included with this configuration of the microphone.

Related Questions and Answers

Q: 1. I read some posts about unstable connection with Sennh EW100. I want to use it with Sennheiser EW100G3 system. Everyone have problems with EW100 or it were just defective?

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.

Q: 2. Hello, what's the difference between this COS-11D and the one with the mini connector ? Both are advertised for use with the Sennheiser EW wireless system, but the mini connector version is more expensive.

A: No accessories will be included with this version.

Q: 3. I've plugged this in to my recorder via the Senal PS-48B-35H Phantom Power Supply that's listed as a recommended accessory for this mic, with 48V phantom power turned on. However, I'm getting a very very low signal from the microphone, peaking at around -32Db even with the gain on my recorder turned all the way up. Did I get a dud or is there something I've missed here?

A: So you checked the gain, have you checked the fader? Is their a pad setting switched on the recorder or the Senal? My last suggestion is to check the voltage of LR44 batteries. Maybe they're about dead. Try switching to providing phantom power from the recorder.
