Just wanted if you guys knew if Bluetooth 2.0 with EDR is A2DP compliant? I just bought a pair of Logitech Freepulse Wireless headphones, and I was hoping to use the Stack (don't even know what that means) on my Tablet PC rather than the adapter that was supplied with the headphones. I heard that anything after 1.2 was A2Dp compliant by default, but I can't really know for sure. I'm having problems connecting the bluetooth device. The computer detects it, I've entered the right passkey, but it refuses to connect.
