The white Sanken COS-11D Omni Lavalier Microphone for Lectrosonicsfor 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. Accessories are sold separately and are not included with this configuration of the microphone.

Related Questions and Answers

Q: 1. I bought this one. I have a question. If i connect sony transmitter this without phantom power, is it operating?

A: The COS-11D requires 3 to 10V of plug-in power, not phantom power. Phantom power is higher voltage of 12 to 48V. The Sony transmitter will supply the proper amount of plug-in power needed for the COS-11D.

Q: 2. does this have an adaptor for a 4 pin AT receiver?

A: I do not have an adapter but here is the mic with the 4 pin hardwired. https://www.bhphotovideo.com/c/product/1200538-REG/sanken_san_11danbkh4at_cos_11d_omnidirectional_lavalier_microphone.html

Q: 3. Will this work with the Rode Wireless Pro?

A: The Rode Wireless Pro transmitter provides 3.3V of plug-in power and the Sanken COS-11D requires at least 3V to operate. The Rode Wireless Pro transmitter mic input is also compatible with 1/8'' TRS Sennheiser style connectors. In light of this, the Sanken COS-11D with 1/8'' TRS Sennheiser style connector will work with the Rode Wireless Pro system.

Q: 4. Will this work with Sennheiser AVX?

A: It should work just fine assuming you are using a 1/8 locking connector for the bodypack.

Q: 5. Will this work with the new Sennheiser XSW-D Portable Lavalier Set? I'm wondering about power and plug. Also, will I even notice an improvement over the included ME2-II?

A: Yes it is compatible. Yes you should notice an improvement in quality.

Q: 6. 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: 7. this model work with lectro ssm,right?

A: Yes it will.

Q: 8. Is this compatible with Sennheiser G4 ew100 ?

A: No, this version of the Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & 3.5mm Locking Connector is compatible only with Sony Wireless Bodypack Transmitters. For the same microphone but wired for compatibility with the Sennheiser SK 100 G4 Wireless Bodypack Transmitter that is included with the ew 100 ENG G4 Camera-Mount Wireless Combo Microphone System, you will need the Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & 3.5mm Locking Sennheiser Connector - with Accessories, Gray (B&H # SAC11WNSETRG).

Q: 9. Sound devices a20

A: This Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & LEMO 3-Pin Connector for Wisycom Transmitters may not work with the Sound Devices A20-Mini Digital Wireless Bodypack Transmitter and Recorder (B&H # SOA20MINI). The A20-Mini can be used with microphones that have a LEMO 3-pin connector wired for compatibility with Sennheiser transmitters such as the Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & LEMO 3-Pin Connector for Sennheiser Transmitters (B&H # SAC11ANSELBE), which is the same microphone with the appropriate wiring configuration.

Q: 10. Can the Sanken Cos 11d be plugged directly into a camera, specifically the Panasonic G85? If not, what is a high end lav mic you would recommend that could be used like this?

A: The Sanken Cos 11D comes in a variety ends. If your's ends in a 1/8 TRS then it will fit into your camera. I plugged mine into a Nikon D610 and it worked fine. I was surprised, because I thought it would require phantom power. Maybe the Nikon supplies that. I even tried using a 1/8 TRS 10 foot extension cable with a barrel connector to allow for normal distance of interviewing someone. It still worked.
