As long as I was at home and had played was less of a problem but in the few times I've used it for making calls on the go I got a huge problem than on a long journey in one of the battery was empty and I do not auflanden the headset in the car could. Since her I always wanted a BT headset which you can recharge via micro USB to charge it with the Car charger to my smartphone.
I have now decided to use this headset and was very pleasantly surprised by its quality. I have the black / gray version. She looks very discreet and fits very well in the ear. I use to both the ear plugs as well as the temple. In order for the headset sits very stable and stays in place even after prolonged not wear.
The NFC feature works without problems. Of course I did not until I had my Nexus 4 linked read about it and got it to test separately deleted again from the list. I'm excited how easy it is now.
I for some years a mobile 2. possess (work phone) I actually expected that I may have joined only 1 smartphone and if the other phone is ringing I just have to change. I have no doubt the product description but not carefully read through this headset can be connected to 2 smartphones simultaneously. This works without any problems. First to tie the 1st smartphone so, then the 2. It really is well described in the manual.
The sound is very pleasant. I also used during the mowing lawns to hear it today to MP3s. I have not the slightest electric lawn mower but I have heard the music well.
Now for the most interesting, which is why at all a BT headset buys. During a telephone conversation, I have a very good sound. The other party is very clear to hear. On the other end of the line you realize no difference to normal calls with the smartphone, even while driving can be heard no big noise.
I am of this BT Headset and am pleased that I chose for this. To be above all the possibility with 2 devices connected simultaneously makes this device just the right headset for me!
