Editing For me it was like many also a wired headset went on his nerves. I have this very good, even in the P / L ratio, headphone now have often worn while jogging. He does not press and stays where who is what is important. My note is housed here in the back pocket of my running shorts, about problems with the connection between the headset and the phone, I could not complain, just as the battery was already very weak, there was a problem that is normal but I mean. And that's the only criticism when charging it via USB cable we learn not about the charge, via Bluetooth is here on the phone this is not recognizable. Too bad, because one could better plan the next charging and conserve battery power.
