Shure BLX14/SM31 Wireless Bodypack System

The Shure BLX14/SM31 is a wireless system combining a bodypack transmitter with the SM31FH headset microphone. What stands out about the SM31FH is its moisture resistance — it is built to protect the electronics in sweaty or humid working conditions.

That makes it the right choice for fitness instructors, teachers running intensive cardio classes such as spin or step, and gym staff who talk continuously; sweat and humidity can shorten the life of an ordinary headset, while the SM31FH is built to withstand those conditions. The garment clip secures the cable and the windscreen reduces breath noise. Up to 14 hours of battery life covers back-to-back class schedules.

For more static use such as office presentations a standard headset like the PGA31 is sufficient; the SM31 is an option designed specifically for physically demanding environments.
