I buy they for be compact , adjustable , and comfortable . Mine shatter on one side in the joint area that hold the right ear piece . they become unusable . fortunately there be enough leave to where I be able to use a upholstery staple as a dowel , epoxy , and super glue to put it back to a functional state . it take two day . and it do not look the same . unfortunately , I buy these at Fry 's and pay too much for they . I be save for a pair of beyerdynamic dt 770 and these will become my portable\/spare pair .
