Having seen on the PC of a friend who owned an integrated dongle, which could play music directly from their smartphone on his computer via BT I loved it. I ordered this adapter with big doubts on the fact that it can exercise this functionality what was my surpise! This is indeed the case! It is quite possible to stream audio from a phone with A2DP service included with the driver installation CD! Quality side is perfect, the sound does not distords, no cuts and no sound lag.
The only gripe I have is software. Indeed the sound in the A2DP player is not adjustable despite the very present reglette to the screen so you will have to juggle the ruler of the system but nothing serious, and given the price, it is only the chipotage .
Also tested with a PS3 controller to play emulators => Impec! No problem with MotionJoy. Detects the problem without dongle you just have to select the USB port to "Load Driver" and go.
Brief 7 for a Bluetooth dongle 4.0 plus it's really very cheap compared to adapters that can be found in stores or otherwise. And finally it is small enough, for my part it does not matter as it is plugged into the back of the PC, so invisible.
A2DP tested and approved with iOS 8.1 iPhone 5S
