I have a pair of these headphone about 3 year ago and really enjoy the sound and comfort but eventually they fall apart . my mistake be not purchase another pair ... instead I purchase the koss portapro . while the portapro be nice , I genuinely prefer the sound and build the Koss ksc75 provide . the portapro have a little too much bass make the sound of my music someway muddy and overall not accurate . you will love the Koss ksc75 ! check out the LMA when you make the wise decision to purchase these can : -lrb- ... -rrb-
