Product Overview
The Sennheiser HT 747 in yellow is a sweat-resistant fitness headset microphone for instructors who need clear, hands-free speech over amplified music. Its supercardioid fitness headset microphone capsule concentrates on the wearer's voice and rejects ambient noise, reducing feedback with PA systems and monitors. A locking 3.5 mm connector makes this Sennheiser bodypack headset mic compatible with a wide range of Sennheiser wireless transmitters for commercial fitness and presentation systems.
Product Description

The HT 747 is built for high-movement settings such as cycling studios, aerobics rooms, and gym floors. It secures with dual ear hooks and an adjustable neckband, and the flexible boom arm holds the capsule close to the mouth for consistent levels. At 48.5 g including the plug, it stays comfortable through long classes, and the sweat-resistant construction withstands repeated high-intensity use. The supercardioid pattern keeps the focus on the instructor in rooms with hard surfaces and loud music. The roughly 4.9 ft cable terminates in a locking 3.5 mm connector compatible with Sennheiser bodypack transmitters and many third-party devices that share the same wiring. The yellow version is easy to identify in shared equipment pools and ships with one HT 747 windscreen. For multi-studio facilities, it provides a consistent instructor mic that integrates with existing wireless inventory.
