The black Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity and 3.5mm Locking Sennheiser Connector is 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. Accessories are available separately and are not included with this configuration of the microphone.

Q: 4. 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.

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

Q: 7. Have TASCAM DR-10 -- Will this work and what is the name of the locking connector I need?

A: This Sanken COS-11D microphone comes with a 1/8 TRS locking connector (it screws onto the wireless transmitter so it stays secure). It is advertised for the Sennheiser G3 transmitters but looking at the Tascam DR-10 it appears to have the same 1/8 TRS plug, so it should work fine.

Q: 8. 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: 9. Is this wired for Servo Bias or Universal?

A: Just kidding. I can't read......
