I am a true friend of Ultimate Ears. Great sound, best fit I was able to learn so far and an absolutely fair price. Unfortunately, I am now in my third pair of 600vi in 12 months. With all the same problem: Cable quality. Both the plug and the earphone tear the cable when used daily quickly and after 6 months then falls from one of Ohrhörrer. UE replaces the equipment very accommodating. Nevertheless, unfortunately, I go back to the search for the best earphones for my mobile devices. Maybe recommended for those who deal with cable always gentle, but for the "schnellaufwickler" and "in-the-pants-Packer" it probably means keep looking.
