Description

The DPA 4466-OP-R-B90 CORE+ Omnidirectional Headset Microphone in black with a MicroLock connector is a premium, dual-ear headset designed for maximum audio clarity and rugged reliability in live, broadcast, theater, and corporate environments. It features DPA's advanced CORE+ technology, offering greater clarity and an impressive dynamic range while effectively eliminating distortion-even at extremely high SPLs up to 144 dB peak.

With its refined, award-winning headset frame, the 4466 ensures a secure yet comfortable fit for all head sizes, thanks to its three-point ear grip and one-size-fits-all design. The lightweight, low-profile frame is treated with a matte, non-reflective finish to minimize visibility on stage or on camera. The omnidirectional 5.4 mm capsule captures sound naturally and consistently, even with head movement, making it ideal for active performers or speakers. The MicroLock connector provides a secure, durable interface for professional wireless systems, offering a new standard of dependability and ease of use in headset microphones.
