The manufacture of headphones is poor. I inserted the kit in my phone. I tried to call. When I moved the plug, the sound went from the left ear to the right ear. And then my phone has planted: it looks like a short circuit! It's pathetic but normal at this price!
The only positive point I recovered reel which I hope will serve me to wrap my old headset. In fact if you want to get a winder, it is better to recover the USB cable because it was just a bit to wrap my new cable.
