Those HD600/650 guys, they're serious, man. You mention other phones in there at the risk of your life. I saw a DT880 guy stagger out of that thread the other day with his shirt ripped, scratches all over him and a knife sticking out his back. 'I'm never going back in there," he said, just before collapsing. I would have called an ambulance if I'd thought there was any hope for him, but he'd stayed in there too long. However, there will be an investigation.
