SM31FH FITNESS HEADSET CARDIOID CONDENSER MICROPHONE WITH WINDSCREEN / TA4F CONNECTOR
The Shure SM31FH is a rugged cardioid condenser headset microphone specifically engineered for fitness instructors and active performers. Its moisture-repellent hydrophobic fabric safeguards the microphone cartridge from corrosion in humid environments, ensuring durability and longevity. The lightweight wireframe headset offers a secure and comfortable fit, while the flexible gooseneck allows for precise microphone placement. Equipped with a TA4F (TQG) connector, the SM31FH seamlessly integrates with Shure wireless bodypack systems, providing freedom of movement during high-impact activities. An included windscreen minimizes plosive sounds and breath noise, delivering clear and intelligible vocal reproduction.
