DPA 4288-DP-F-C90-MH

The DPA 4288 CORE+ Cardioid Flex Headset Microphone in brown, with a 100 mm boom and MicroLock connector, delivers premium-quality audio in a comfortable and low-profile dual-ear headset design. Ideal for demanding applications such as theater, live events, and broadcast, it offers secure, stable placement and blends naturally against the skin for minimal on-stage visibility.
