DPA Microphones 4288 CORE+ Cardioid Flex Headset Microphone with 100mm Boom and MicroLock Connector (Brown)
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.
Built around DPA's highly regarded 4088 directional capsule and enhanced with CORE+ technology, this headset ensures clean, natural sound with significantly reduced distortion-even at high sound pressure levels. Its cardioid polar pattern provides excellent isolation from surrounding noise, making it well-suited for use in noisy environments or multi-microphone setups. The 100 mm boom offers precise mic positioning, and the durable MicroLock connector adds a secure, long-lasting connection that is fully backward-compatible with MicroDot systems. Lightweight, rugged, and designed for all-day comfort, this headset is a go-to solution for professionals who require clarity, stability, and discretion.
