Need help choosing?

First choose the colour that best suits the talent or costume: Black, Beige, Grey or White. Then match the connector to the transmitter. Wisycom MTP, Sound Devices A20 and suitable Sennheiser 5000/6000 packs use the 3-Pin Lemo option. Sennheiser Evolution systems use the Sennheiser-wired locking 3.5mm version, while Sony systems need either the Sony-wired locking 3.5mm or the separate 4-Pin Hirose version depending on the transmitter. Lectrosonics uses TA5F here; Micron uses the small 6-Pin Lemo; Audio Ltd 2020/2040 uses the large 6-Pin Lemo. If you are unsure, send us the exact transmitter model before ordering.

The COS-11D is an ultra-miniature omnidirectional lavalier microphone with excellent RF immunity, moisture resistance and transmitter-specific connectors.

A long-standing industry standard for film, television, broadcast and location sound, the COS-11D uses Sanken's vertical-diaphragm design to deliver clear, natural speech from a capsule only 4mm in diameter. Its water-resistant front mesh and rugged 2.1mm cable are built to handle perspiration, cosmetics and demanding production use. Select the microphone colour and the exact connector required by your wireless transmitter.

• Sony UWP 4-Pin Hirose is a different termination from the 3.5mm Sony version; confirm the transmitter connector before ordering.

Transmitter Wiring Matters

Choose the Correct Connector

Select the connector for the exact transmitter system you use. Sennheiser and Sony locking 3.5mm connectors look similar but use different wiring and should not be treated as interchangeable.

4mm Capsule

Small Enough to Hide

The 4 x 16.1mm capsule is easy to conceal in clothing, costume or hair while Sanken's vertical diaphragm provides a larger effective diaphragm area than the tiny housing would suggest.

RF + Moisture Resistant

Built for Modern Wireless Production

The COS-11D was developed to reduce interference from digital and hybrid wireless transmitters. A water-resistant front mesh and durable moisture-resistant cable help protect the microphone from sweat, makeup and challenging location conditions.
