The Shure SM31FH-TQG is a professional condenser headset microphone system specifically engineered for high-energy fitness instruction, dynamic presenters, and performers who require robust, hands-free audio with superior intelligibility. The system features a discreet, over-the-ear design that securely positions a high-quality condenser microphone capsule close to the corner of the mouth. This proximity, combined with a supercardioid polar pattern, provides exceptional gain before feedback and effectively rejects ambient noise such as loud music, crowd sounds, and room reverberation. This ensures the instructor's voice remains clear and present even in the most challenging acoustic environments of gyms, fitness studios, and large conference halls.

Designed for durability and comfort during prolonged, vigorous activity, the headset utilizes a flexible, lightweight metal headband and soft, secure ear hooks that ensure a stable fit without causing discomfort. The microphone element is housed in a rugged casing with an integrated windscreen to minimize plosive breath sounds. The system operates on standard +48V phantom power, which is supplied via the connected wireless transmitter bodypack or wired mixer. Its integrated cable typically terminates in a common 3.5 mm mini-jack (often in a locking configuration), ensuring compatibility with a wide range of professional wireless transmitters and wired microphone power supplies.

As a specialized tool for the fitness and presentation industries, the Shure SM31FH-TQG delivers reliable, high-quality audio that instructors and presenters can depend on class after class. Its combination of a secure, comfortable fit, excellent noise rejection, and clear vocal reproduction makes it an ideal choice for leading group exercises, teaching workshops, or hosting interactive events where constant movement and clear communication are essential. The microphone empowers users to focus on their performance and audience engagement without being hindered by audio limitations.
