Bluetooth’s purpose is to provide a means for devices to communicate over short distances securely without wires.
Bluetooth devices have built-in support for one or more "profiles." These are similar to the various file formats computers support. A computer only knows (natively) so many file formats. When two bluetooth devices understand a particular profile, they can communicate data provided/exposed by that format.
For example, many (stereo) bluetooth headphones available today support stereo reception, along with the more basic monophonic reception designed for earpieces. If the device they are connecting to only supports the monophonic profile, then that is the extent to which they can communicate.
I don’t recall offhand which profiles the PS3 supports.
