I have absolutely huge ears, and so rarely wear closed headphones: I didn't note the closed headphones on the 800C, and so found them almost comfortable, but not quite; my other friends have no problems and love the headphones. I got the 1000C instead, and love them, and now need to sell the 800C.
They sell only through Audiocubes, for $380 + shipping. I've only used them fo a few hours, have the original box, receipt, and virtually all packaging (I'm sure I threw away a plastic bag here or there), and will take your best offer + shipping. Give me a PM and we'll work something out.
