The beige Sanken COS-11D Omni Lavalier Mic with Sennheiser Connectoris 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. A metal windscreen, holder clip, rubber mount, and plastic case are included.

As additional options for a Sennheiser wireless system that you can use in Italy without a license, you may want to consider the Sennheiser AVX-ME2 SET Digital Camera-Mount Wireless Omni Lavalier Microphone System (B&H #SEAVXME2SET4) or the Sennheiser XSW-D LAVALIER SET Digital Wireless Omni Lavalier Microphone System (B&H # SEWXSLSTR). The AVX system operates on the 1.9 GHz frequency band and includes a plug-in receiver which can be connected to a 3.5mm mic input using the included XLR to 3.5mm cable. The XSW-D system operates on the 2.4 GHz frequency band and can also be used with an XLR female to 3.5mm cable to connect to a 3.5mm mic input.
