I have a pair of AKG N400 that have been going for 1.5 years of 8+ hours, 5-6 days/week use. I wear them at work until they die, let them charge for an hour, put them in again, and repeat until done with work. They have survived two summers of constant sweaty ears (I work outside) as well as cold, rain, and snow. A charge doesn't last quite as long as it used to but considering how many cycles they've been through I'm very happy with them.
