Very good product, good quality. With a compatible smartphone aptX Bluetooth, sound quality is really excellent. Simply connect the receiver to the auxiliary input of the car radio, and in-car charger. The in-car charger supplied has an additional USB port 2.1A, much more effective than a 1A charger to charge the smartphone. The NFC feature is very convenient to connect the phone, but recognition has sometimes a little hard to do (the pairing seems to work better when the receiver is not on its magnetic base). The NFC connection is of course possible, just go to the Bluetooth settings of the phone to find the receiver. I have the "old" version the next / previous track buttons work but are reversed. The version has now sold over this problem. The magnetic base to stick (adhesive back) on the instrument panel is very convenient to attach the receiver. The receiver can also transfer the sound when you receive a call when the phone is connected, but I did not test this feature. Just click the center button to answer / end. The receiver also loads the CVC function (Clear Voice Capture) that attenuates background sounds during a call to improve the sound quality for the caller. Finally, the SAV (TaoTronics) is very responsive and pleasant. I recommend this product for all its qualities!
