FM Radio / Silent Disco Headset

Maybe add some form of fm radio receiver ic to use the badge for Silent Disco so the headsets won't get lost.

just checked: last years silent disco was broadcast around the 868 MHz band. Not sure the fm receiver ICs can operate outside of the traditional FM-Radio frequencies....
maybe it's more of a shitty addon option anyway...
