General

The logical choice for professional fitness instructors, the Shure BLX188E/SM31 wireless headset system includes a two-channel BLX88 receiver, two SM31FH headsets and two BLX1 bodypack transmitters. Easy to use, this complete system features a smart SCAN function that quickly finds and selects the cleanest and most interference-free channel at any given moment, as well as clear LED indicators and a straight-forward menu screen that displays both the group and channel info. Adjust the gain level and select the preferred channel via the bodypack, and while the SM31FH headset boasts a hard-wearing and waterproof design, it still manages to keep things comfortable yet secure during longer classes.
