DPA d:fine CORE 4266 Omni Flex Headset Mic, 110 mm Boom, Beige, 3-pin LEMO

The d:fine 66 Headset Microphone combines the legendary sound of the 4066 Omnidirectional Capsule with the lightweight and flexible d:fine Headset system. This condenser mic is easy and fast to adjust and it offers clean and transparent sound quality with lots of headroom.

Like all of the microphones in the range, the d:fine 66 Headset Microphone offers accurate, natural voice intelligibility and very high SPL capabilities. Users can both speak and sing into the mic with no hint of distortion. The microphone capsule is also optimized for low distortion as well as humidity resistance.

The d:fine 66 Omnidirectional Headset Microphone is available with single- or dual-ear mounts. Single-ear mount variants are the quickest to put on and often the best choice when miking needs to be fast and easy. Dual-ear mount variants sit more securely around the head and are ideal for active performance situations.
