The white Sanken COS-11D Omni Lavalier Microphone with Reduced Sensitivity and Hardwired Servo-Bias TA5F Connector for 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 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 TA5F connector and is wired for use with servo-bias Lectrosonics transmitters. A metal windscreen, holder clip, rubber mount, and plastic case are included.

Q: 2. How does this compare to the rode filmmaker?

A: The Wireless GO II System is more versatile than the Filmmaker Kit and offers more features. The receiver has two separate channels that allow it to be used with two transmitters at the same time, The transmitters also have onboard recorders that can capture up to seven hours of uncompressed 24-bit / 48 kHz WAV audio or 24 hours of compressed audio directly to each transmitter without the need for an SD card. The free Rode Central app (currently for Mac and Windows -- iOS and Android compatibility coming soon) allows you to access the recording features and adjust settings, then export and optimize the recorded files from each transmitter and save them to a computer in various formats such as MP3 or WAV in 16-, 24-, or 32-bit float. The Wireless GO II also uses new patent-pending technology with 128-bit encryption that provides clear audio transmission up to 656 feet (line of sight). It's an impressive system.

Q: 4. Looking to use this both on a set and in the field. I would prefer a way to hide the mics when on set, what is the range of quality audio pickup (say if it was placed on the table out of sight) or would it still pick up that quality audio under a jacket or shirt?

A: Any microphone will give you it's best sound when placed closest to the subject you are trying to record avoid having it far from the subject you recording, the best recommendation I can give while using this system is to add a 3.5mm lavalier microphone, lavalier microphones are meant to be used on the subject you recording giving you the best sound and are small making it easy to hide so it's not being seen in the video. https://www.bhphotovideo.com/c/product/1558252-REG/rode_lavgow_lavalier_go_professional_grade_wearable.html

Q: 10. How good/bad is the Wireless Go II if I use it like a shotgun mic both receiver and one transmitter on the same camera for typical outdoor YouTube videos?

A: The Rode Wireless GO transmitter is not going to work like a shotgun microphone. The transmitter's built-in mic is omnidirectional and shotgun microphones are typically very directional and designed to pickup sound from a distance while reducing the background noise. The transmitter's built-in mic is intended to be used while it is attached to a person for picking up their voice from close up. If you need a microphone to pickup sound while mounted on the camera, then you should use a shotgun microphone for the best results.
