Dear Rofel,
You helped me on another problem approx. 4 months ago. Anyway I just purchased a Bose Solo 15/10 Sound System.
Sorry Kelly, I'm not the guy who helped you before; but, yes there are and many different kinds. Some easier and some harder to use, in fact there are even kits to build your own.
Search eBay for Bluetooth, receiver, you'll need one with an amp, if the Bose doesn't have one built in. But, otherwise, they're just like paring any other bluetooth device, like a headset, only with these, you don't need the speakers in the headset. In fact, if you bought a cheap bluetooth headset, and the Bose had it's own amplifier, you could wire the headset speaker wires directly to the speaker inputs of the Bose, if you know how, and you might just have a really cheap one!
Good luck, and let me know if this helps!
