The gray Sanken COS-11D Omni Lavalier Microphone for Sonyis 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. Does this work and lock with the Tascam DR-10L?

A: The Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & 3.5mm Locking Sennheiser Connector is not advised for use with the Tascam DR-10L, as it requires 3V of plugin power at a minimum and the DR-10L can only provide 2V.

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.

Q: 3. Hi, whats the length of cable typically on these lavs?

A: Jim: Unfortunately I'm very far from home and my Sanken lav mics at the moment. The length is actually very long. I think it's about 10 feet. If you are worried about the length being too short: don't worry. If you have a very specific need let us know more. I use my mics mainly for interviews so I have the extra wire length gently wound up and clasped.

Q: 8. 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: 9. Will this work with Sennheiser AVX?

Q: 10. 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.
