DPA 4166-OP-F-F90-ME

The DPA 4166 CORE+ Slim Omnidirectional Flex Earset Microphone in beige, with a 90 mm boom and MicroLock connector, offers discreet, high-clarity voice capture in a compact, comfortable design. Tailored for professional use in theater, broadcast, and corporate settings, its beige finish allows for near-invisible placement against light skin tones-ideal for on-camera or stage use.

At its core is the trusted 4060 capsule, upgraded with CORE+ technology for exceptionally low distortion and a detailed, natural sound signature. The shorter 90 mm boom provides a tighter fit, making it perfect for smaller faces or close-mic positioning. The newly introduced MicroLock connector ensures a robust, secure connection with enhanced durability and full backward compatibility with MicroDot-based systems. Lightweight, easy to wear, and resistant to humidity, this earset is built for demanding environments where performance and discretion go hand in hand.
