Sennheiser HT 747 – Black Fitness Headset Microphone

Product Overview

The Sennheiser HT 747 is a sweat-resistant fitness headset microphone built for instructors who need clear, hands-free speech over loud music and full rooms. Its supercardioid fitness headset microphone capsule focuses tightly on the wearer's voice while rejecting ambient noise, which reduces feedback when paired with PA systems and floor monitors. A locking 3.5 mm connector makes this Sennheiser bodypack headset mic compatible with a wide range of Sennheiser wireless transmitters, so it drops into existing commercial sound systems for group fitness and presentation use.

Product Description

The HT 747 is designed for high-movement environments such as cycling studios, aerobics rooms, and gym floors where a presenter is in constant motion. It secures with dual ear hooks and an adjustable neckband, and the flexible boom arm positions the capsule consistently close to the mouth for stable levels. At 48.5 g including the plug, it is light enough for long classes, and the sweat-resistant construction holds up to repeated high-intensity use. The supercardioid pattern keeps the focus on the instructor, which is important in rooms with hard surfaces and amplified music. The roughly 4.9 ft cable terminates in a locking 3.5 mm connector that mates with Sennheiser bodypack transmitters and many third-party devices using the same wiring. This black version ships with one HT 747 windscreen for wind and plosive control. For facilities standardizing instructor mics across multiple studios, the HT 747 offers a consistent, serviceable headset that integrates with existing wireless inventory.
