Independent shopping perspective
Built for fitness instruction, the SM31FH is a cardioid condenser headset mic with moisture protection where sweat and humidity are part of the job. Its lightweight wireframe headset stays low-profile during active movement, while the flexible gooseneck lets you position the capsule precisely. The TA4F connection makes it a direct option for Shure wireless bodypack systems using that connector. A windscreen is included to reduce breath, wind, and plosive noise.
