I don't know how Koss does this, but since they first came out in 1984 they have managed to update the drivers and keep the same look, feel and extremely impressive sound . I will never own a pair of these headphones. The sound is no worse than many headphones that are four times more expensive. Replace your standard ear pads with Yaxi ear pads and your kit! ππ»
