Sanken COS-11D Overview

The gray 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.

Locking 3.5mm Connector

Compatible Wireless Transmitters

  • Sennheiser: Works with Sennheiser bodypack transmitters equipped with a locking 3.5mm connector, including the Evolution (ew), XSW-D, and SpeechLine (SL) Series
  • Also works with many third-party wireless transmitters and portable audio recorders that are equipped to supply 3 to 10 VDC through a locking 3.5mm connector wired for Sennheiser compatibility.

Broadcast-Quality Sound and Dependable Performance

Subminiature Mic with a Big Sound

The camera-ready COS-11D features a subminiature capsule that enables the microphone to be inconspicuous and easily disguised in clothing or costumes. The unique vertical diaphragm design offers a clear and natural sound optimized for the human voice.

Normal Headroom for Standard Speech

This version of the mic features a normal sensitivity setting for standard speech at levels up to 123 dB SPL.

Omnidirectional Polar Pattern

The forgiving omnidirectional polar pattern picks up sound from all around the mic and provides a consistent frequency response, even for off-axis sound. This helps to supply clear, intelligible speech and vocals, even when the talent isn't speaking directly toward the microphone.

Tough, Water-Resistant Construction for Indoor/Outdoor Locations

The water-resistant front mesh screen provides reliable protection from perspiration and moisture, making the mic a solid performer in all kinds of weather. The rugged cable is also built to resist moisture and handling noise and stay pliable, even after repeated uses.

I use the Sanken COS-11D lavs for celebrity & politician interviews so I need something that delivers incredible audio quality and reliability, these do not disappoint. Way better than anything else I've ever tried, you just get a rich full sound that you'd expect from a larger microphone. As with all lavs, the plug end is delicate so it's always advisable to remove from your talent before they take it upon themselves to rip them off!

Awesome

This mic is really small and also sounds great!! Sometimes if the boom could not be near to the action the sanken would definitely make it. Sound much better than a lot of shotgun mics. It is really easy to hide and has several accessories that make my life very easy in the set.

Nothing special

I will not comment on a durability and a build quality of this lav, yet the sound quality of this mic is comparable to Aspen lav mic which can be had for around $30. Again this comment is only about sound quality of the mic.

This is a fantastic omni-directional mic. Hides well and outstanding performance for sit down interviews or walk and talks.

Asked by: Hamad
Unfortunately Sanken doesn't make a specific model for the Rode Wireless Go. If you want a better quality mic option for the Rode Wireless Go, I would recommend BH #COMEMWSFF05B.

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.
