Turn your existing fitness class or outdoor event sound system into a Silent Event with a silent system expansion Kit, featuring Sound Off™ GLO2 EXP Headphones. The premier solution for Yoga, Cycle, or any type of instructor-lead fitness events. This provides an alternative to classes using loudspeakers. 

This portable version of our Sound Off kits has everything you need for holding a "silent" class without needing power from a wall outlet. The Bolt transmitter that is included with this kit is battery-powered and is typically worn on the instructor's waist with the included Bolt Belt. The E-mic headset microphone connects directly into the Bolt transmitter. Music can be played as well using the Bluetooth connection from a smart device to the Bolt transmitter. This means you can have your music and microphone both playing through the headphones to your participants.
