The gray Sanken COS-11D Omni Lavalier Microphone with TA5F Connectoris 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 universal TA5F connector that is wired for use with both servo-bias and non-servo-bias Lectrosonics transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Q: 1. 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: 2. Is this the same connector that will fit the sennheiser G3 transmitter?

A: This Sanken COS-11D (MFR# COS-11D-HWM-TRS-BE) has the correct wiring for the Sennheiser Evolution wireless G3; trs 3.5mm male locking connector.

Q: 3. 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: 4. 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: 5. Has anyone used it with the new RODE Wireless Go system? I am wondering if it would work and if there would be any loss in the quality of the sound compared with the Sennheiser systems...

A: You can use a COS11-D with the Rode Wireless Go system, but you will need a version of the mic with a standard non-locking 3.5mm TRS connector, as the transmitter for the Wireless Go does not use the same locking connector that Sennheiser and the other Rode wireless systems such as the Filmmaker Kit require. The Wireless Go is designed with standard 3.5mm connectors on the transmitter's mic input and receiver output, and intended to be very easy to use for general consumers.

Q: 6. Has anyone used this microphone in combination with the Tascam DR-10L's? I am looking to upgrade the microphones provided and this looks like it could be a good option.

A: I have not used this Tascam model with the Sanken COS 11D but have used it with the Tascam DR-40 and other professional recorders. It's a great sounding lav mic and easy to hide.

Q: 7. 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: 8. Will this work with a Sennheiser G3 receiver/transmitter set?

A: Yes. This mic will work with the Sennheisser G3.

Q: 9. Can I plug this directly into a Sony A7III?

A: The Sanken COS-11D Omni Lavalier Microphone with Normal Sensitivity & 3.5mm Locking Connector for Sony Transmitters (With Accessories, Black) is made specifically for Sony wireless transmitters and is not able to be connected directly to camera inputs such as that of the Sony A7III Camera.
