The deal is that unless the phone you have has a particular profile - whose code I cannot remember just now - you cannot listen to mp3's on your stereo Bluetooth headphones. I know because I bought really nice stereo headphones hoping that I would be able to listen to music with them and no go. The profile is 4 letters/numbers long, it is something like 2DCD or something that looks like that. If you see that in a phone spec list then you can do what you want to do and hear that music on the Bluetooth headset otherwise, we are stuck with wires.
Can't get the headphones to work while listening to Mp3's. Works well with the phone. Any Tips?
