R.I.P. March 29th 2012 . I love Sennheiser and they sound quality but I be utterly disappoint after six month . the build quality of these headphone be cheap especially the wiring . I take great care of my earphone and it even have a case . I still have my iPod Video Class 60 gb in perfectly work condition . I be a audiophile where I will sacrifice eat out for a good set of headphone because I do not like to compromise when it come to quality to my ear . I be very meticulous when I finish use they and wrap they in a certain manner to avoid they be tangle . warranty 2 year but do not get you hope , it will not get you anywhere . my brother have recommend I to switch to Klipsch IMAGE S4 In-Ear enhance Bass Noise-Isolating Headphones -lrb- Black -rrb- Let 's see how do they fair in a couple of week .
