Pros: Great sound, accurate, durable,
Cons: pleather pads stiffen quickly
I've had a pair for about 4 years now wear them daily while working. They're extremely durable, although the oils from your head get absorbed into the ear pads and they stiffen up, not a problem if you're the only person wearing them since they mold to your head. Occasionally I'll buy new earpads but its not that big of a deal for me.
