Too bad, so this product is for me not useful. Because actually appear processing, inbes. also the cable, pretty good and workable. The buttons can be good press, the cable length is OK and also the plug seems well suited for everyday use.
But all this I could not continue to use, because the volume as described on a Nokia Lumia 520 and Samsung Galaxy S2 is not nearly enough. Therefore, as a compromise 3 points for a neat-made headset, but what may work correctly only on a few models.
