There are systems oriented to gyms that will work for you. It's been a couple of years, but I've seen one that had, I think, four programs transmitted via RF to headphones that could choose which channel to listen to.
I am supposing if the original thought was Bluetooth, the jump to specialized listening equipment with multiple channels will be a tremendous jump in price.
