I bought these headphones in June 2013, we are in September 2013 and I had no problems. I went on a trip to Vietnam with impeccable and are for travel in noisy trains and planes because they isolate the outside noise pretty well. I would have preferred that a cable tangle but that the relatively well. when doing sports (cycling or running) they hold great I have no problem at this level, however as is intra there is some friction between the cable and not.
