And not only that I had problems, but also there that the stopper held in the ear properly, because none of the variables it could hold in my ear and slide out easily.
And most important of all the points, as far as the Bluetooth.
First it verbindete eternally not, whether it was switched off or in stand-by mode, it simply was not working ..
When it was finally "connected" with my smartphone (HTC One .. the latest software version), either the error was that the device was indeed off, or there was after several attempts the error cause "Incorrect entered connection code", which according to Instructions "0000" is the .. but they could not enter because it fatally flawed responded in connecting what a setting and entering the code was impossible.
I suspect that I got a faulty delivery, what is beautiful as already recognized on the package, because the plastic bag in which the knob stuck, had a crack .. either has this been used and returned & not repaired or not prepared properly again. Or one does not seem too well to deal with the goods in production, which could be in my view on the case.
My review, just was just appalling .. the only positive because I know for me never to buy anything from China ..
