Shure BLX14/SM31 – Professional Wireless Audio for Active Performers.

The Shure BLX14/SM31 Wireless Fitness Headset System delivers clear, professional-quality audio for instructors, presenters, and performers who need hands-free operation and freedom of movement. Perfect for gyms, fitness studios, schools, places of worship, conference rooms, and live demonstrations, this system provides reliable, wireless sound even during high-energy sessions.

The SM31FH headset microphone features a unidirectional cardioid condenser capsule and hydrophobic moisture-repelling construction, making it ideal for humid or high-intensity environments. Its lightweight, low-profile design ensures comfort during prolonged use, while the flexible gooseneck allows precise positioning for optimal vocal clarity. The included BLX1 bodypack transmitter integrates seamlessly with the BLX4 single-channel receiver for simple setup and dependable wireless performance.

With a range of up to 100 metres (line-of-sight) and up to 14 hours of battery life from two AA batteries, instructors and performers can move freely while maintaining consistent, high-quality audio. One-touch QuickScan frequency selection on the BLX4 receiver ensures interference-free operation, and dual-colour LED indicators help monitor audio levels and battery status at a glance.

The system includes the BLX4 receiver, SM31FH headset with BLX1 bodypack transmitter, clothing clip, windscreen, power supply, AA batteries, and user guide — a complete solution ready to use straight out of the box.
