I've had the Solisto.Pro unit for a while now, and it has worked just fine. Recently, however, I've been interested in going after an option with no wires, so I bought a small USB Bluetooth receiver to experiment. It works flawlessly with the Solisto unit! Just plug the device into the USB port, and then connect the 3.5mm to the Aux-In port on your Solisto. My audio is great quality and I've had zero interruptions. Below I've attached the device I bought:

If you would like to keep the option to play through a 3.5mm cable, just buy a splitter and split the port on the Solisto--just don't play two things at once--you could blow your speakers. Somebody may have discovered this trick already, but if not, here's all the info! Cheers!

 

I have a wired system from Scosche that works well (have the M303 for the Xfire) but for HandsFree you need a triple 3.5mm plug (dual is good only for playbacl) and the adapter must have a Mike.
