Product information

General

This 3-piece BLX14/SM31 wireless headset system from Shure is specially developed for fitness instructors and consists of the BLX1 bodypack transmitter, BLX4 receiver with built-in antennas and the moisture-resistant SM31FH microphone. The bodypack weighs only 75 grams and lasts roughly 14 hours on a pair of AA batteries, while the antennas fitted to the receiver are automatically tuned for optimal signal reception. If you're constantly moving around, it's also important that the microphone can take a few knocks and stays firmly in place. That's why the included condenser microphone is built with physically-active use in mind.

Bax Music Warranty This product comes with a 3-year warranty.
