The processing is in my opinion quite good for the price. The connection to the cell phone did not work at all at first.
Have an iPhone 4s. I wanted to send it back just as much as I was angry, that is not true with the iPhone.
But that was partly because of the bad German translation, which you can not just understand. So badly translated, just in the Google translated copies ready. But then I again tried to understand them. And then I read it: I have the button for pairing hold 7 seconds, and not as I did, just 4 seconds.
It worked immediately. Now I am very satisfied. The Sound and the handling of the buttons,
without seeing (because the listener has to yes) works quite simply. In the past I have always grope me. And then it was the wrong button. Not so here.
One battery charge lasts for very long.
Also from me a clear recommendation.
