The Shure BLX14/SM31 is a wireless headset system built specifically for fitness instruction, pairing a bodypack transmitter with a moisture-resistant headset mic rather than a standard vocal capsule. It's aimed at group fitness instructors who need a durable, sweat-resistant microphone that survives repeated high-energy classes.


  • BLX4 Single-Channel Receiver: Features microprocessor-controlled internal antenna diversity and one-touch QuickScan frequency selection.
  • BLX1 Bodypack Transmitter: Lightweight, ergonomic design with adjustable gain, up to 14 hours of use on 2 AA batteries, and a 300-foot range.
  • SM31FH Fitness Headset Microphone: A cardioid condenser mic built with hydrophobic materials and a moisture-repelling cartridge housing to resist corrosion from sweat.
  • Simple Setup: Intuitive controls designed for out-of-the-box use without complex configuration.
