Well guys, bit of news here... So I ordered two products on Amazon, one of them really looks like the one from the picture, but not sure since it is FR store, it is from Tao tronics, the other one from another brand. Lets rule this out from the beginning, it was Receiver only -_-... the other one, on the other hand, does transmit, and quite well at that: the pairing is easy and quick, the only thing left was to plug the jack and voilà! On the down side, it is APTX only, so a bit of latency, I ordered another one which is receiver and transmitter, and APTX Low Latency, so I'll keep you guys informed !
