The Sennheiser HT 747 is a headset-style microphone designed for fitness instructors and other active presenters and performers. Featuring bold black styling, the sweat-resistant design offers a secure fit with dual ear hooks and an adjustable neckband. The supercardioid pickup pattern focuses sound capture very narrowly on the headset wearer, picking up less unwanted background sound and helping to reduce feedback problems when used with PA systems and monitor speakers.

The microphone arm is adjustable, allowing users to comfortably position the mic for optimal audio quality. The 4.9' cable terminates in a locking 3.5mm connector that is compatible with a wide range of Sennheiser wireless bodypack transmitters and many transmitters and devices from other manufacturers that use this wiring configuration.
