The HE-500 was bought new at the end of September last year and is about 5 months old. I actually haven't touched my HE-500 since January because I've moved onto the HD800 (hence I'm selling). Overall, I'd estimate about 300-400 hours of usage on the HE-500. Perfect working condition and no scratches or cosmetic damage. Only velour pads have a little dust on them because these pads are pretty much dust magnets, but they can be washed.
