The sound is surprisingly good and the listening experience is given.
Only slightly negative is striking; what other reviewers complained about; that Bluetooth is not really 8-10 meters sufficient - after about 5 meters is closing with good transmission.
What bothers me is that not because I have the phone always in your pocket (traveling, sports) and thus do not rely on the long range am.
Overall, I am very satisfied after a short period of use.
