Despite good looks poor quality

Although the cable looks robust, the contacts appear to be rather cheap. On my Sony Xperia the plug did not fit properly fixed, the always remained shaky and gave so strong disturbances every time I took the device in the hand. With my previous in speakers by Sony and other no-name headphones that never happened. I would like to confirm what others have written, I had to hear something completely unscrew the volume. I'm not a Freaky in terms of sound, but honestly, the sound quality was anything but good. The price is not cheap, there are similar items for half the price, so the pressing power is wrong here. I will send the thing back and'd rather pay a little more. From the purchase, I can only advise.
