I bought these about 2 months back and they have served me very well. This can is not only good at bass; it's good with nearly every genre of music except classical since it's closed-back. I have to say, I did not find them comfortable at all until I put the Beyer dt250 earpads on. I think the pads actually brought the mids more forward and make them overall more balanced as well as very cushy comfortable Wear 'em for 2 hours+ with hardly any discomfort. They are absolutely blemish free and sound as good as the day I bought them, actually better since these absolutely do improve with burn-in. They come with all the original components except the original pads, but you probably don't want those anyway. Take my word for it.
