SM31FH Headset Microphone

The SM31 Fitness Headset has been specially made for aerobics and fitness instructors. Its rugged, wire-form design is built to last, and will stay in place even during high energy workouts. And because it’s been assembled with lightweight components, you can comfortably wear it for hours.

It sounds exceptionally clear too, offering the same quality as Shure’s famous handheld mics. And thanks to moisture resistant fabrics, the mic capsule is completely safe from sweat.

Comprehensive monitoring

With a Shure BLX System, you get wireless freedom with total peace of mind. The receiver’s ‘ready’ LED, telling you when your system is set up and secure. You don’t need to worry about signal dropouts.

If the channel starts clipping, an LED switches from green to red, letting you know when to adjust the transmitter’s gain. There is even an LED monitor to tell you when the batteries are running low on the transmitter. Everything about the BLX Wireless System is clear and simple, for effortless setup straight out the box.
