The brown Core 4166 Slim Omni Flex Headset Mic, 110mm Boom with MicroDot from DPA combines the sound of the 4066 omnidirectional capsule and Core amplifier in a lightweight and flexible two-ear headset. It can be used when miking needs to be fast, easy, and where the person wearing the microphone won't feel the presence of it such as in conference, speech, and active live performance applications.

The Core 4166 gets a 14 dB increase in dynamic range than the Legacy version and is ergonomically designed to fit comfortably. It easily adjusts to fit any ear size and head shape while at the same time, it mounts securely and is hardly visible. By rotating the boom and the ear hook, the microphone can be used on either the left or the right ear. In addition, the connector splits the cable from the microphone boom allowing you to swap broken cables and/or wireless connectors quickly. Finally, it includes three windscreens, a clothing clip, ID rings, and a cover.
