Agreed on headphones for immersion. More specifically for me -- when I really need to focus and I'm around other people, I listen to noise (playnoise.com is good and simple). Anything but noise is just another mental distraction for me. If I listen to music, no matter how ambient, my mind still wants to follow the music instead of whatever it is that I'm trying to focus on.
