The Shure SM31FH is a fitness headset condenser built to survive the one thing that kills instructor mics: sweat. A hydrophobic fabric barrier protects the cardioid cartridge from perspiration corrosion, the wireframe headband stays put through a full class, and the TA4F connector plugs into any Shure bodypack.
