Adding bluetooth dongle to camcorder

Just had this crazy idea that instead of being tethered to the Panasonic HC-x1500 camcorder with a wired headphone I was wondering if plugging into the microphone port a bluetooth dongle might just work with bluetooth headphones.
To be honest I have not seen anywhere on youtube or the internet where this has been tried. if it does the advantages are obvious. May even work on a camera who knows. for the small amout it costs its worth a try, if not the TV is there incase
