When I can't sleep, I need to listen to music to sleep. My wife needs absolute silence. So I always put on my headphones. I've been doing this for a few months now and the most that's happened is I've pulled the earphones out of my iPhone as I tossed & turned. However, I don't think you can strangle yourself with headphones while you sleep. I imagine the force needed to do it is stronger than what you'll face from tossing & turning. I wasn't able to find any info on this anywhere either though, so don't quote me on that - but it strikes me as unlikely, at least in my own experience.
