The beige Sanken COS-11D Omni Lavalier Microphone - Beigeis a subminiature lav mic 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 little 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 Sennheiser transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Related Questions and Answers

Q: 1. Is there an option to connect it to a XLR input camcorder? Also will it work with my phone's 3.5mm headphone port?

A: A Rode VXLR+ 3.5mm TRS Female to XLR Male Adapter with Phantom Power Converter, BH #ROVXLR, will allow you to plug this mic into a camera with XLR input, which would be able to provide 48 volt phantom power to the mic. To connect this to a smartphone, you would adapt the end to TRRS with a Rode SC4 3.5mm TRS Female to 3.5mm Right-Angle TRRS Male Adapter Cable for Smartphones, BH #ROSC4. The smartphone will power the mic in this case.

Q: 2. I found this mic at the video you guys made for Tascam DR-10L Digital Audio Recorder. This unit operates with aaa battery 1.5V However this mic requires 3 to 10V???

A: This is ultimately a question for Tascam. You need to know the voltage provided by the DR-L10. Do not assume it to be the same as the supply voltage.It is true that the COS-11 BP (Belt pack) runs on single AA, but the voltage supplied to the mic is actually multiplied within the belt pack.

Q: 8. 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.

A: It is not designed to work with plug-in power which is typically 1-3 volts.
