I saw someone break an HD800 in the HeadRoom room. He tangled his feet in the cable and yanked it from the table, popping off one of the ear cups. Interestingly, it was one of the pre-production models and Tyll said the retaining pin that had failed was the main component that was redesigned for the current batch. I offered to stomp on one of his new ones to see how well they did, but he wasn't up for it.
