DPA 4188 CORE Slim Directional Flex Headset Microphone, 120mm Boom, Beige, TA4F Mini-XLR (4188-DC-F-F10-LH)

4188 Slim Directional Flex Headset Microphone (4188-DC-F-F10-LH)

The beige d:fine Core 4188 Slim Directional Flex Headset Mic with 120mm Boom and TA4F Connector from DPA combines the sound of the d:fine 4088 directional capsule and Core amplifier in a lightweight and flexible two-ear headset that offers accurate, highly intelligible speech and plenty of headroom for loud vocals. The microphone's electret-condenser capsule provides a crisp, natural sound while its cardioid polar pattern focuses audio capture on the wearer, picking up less background sound and helping to control feedback issues on loud stages where sound reinforcement gear is used.

The flexible design is quickly and easily taken on and off and provides a fit so light and comfortable that presenters and performers will barely notice it during conference, speech, and active live performance applications. The headset is ergonomically engineered to easily adjust and 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 out broken cables and/or microphone booms easily. The 4188 includes a makeup cover, foam windscreen, and a pop screen.
