Trying to record multi-track without headphones is just artistic suicide my friend. You end up with every instrument on every track, and no way to clean up the end result. Always use headphones, and if you still like the ambient 'feel' then only put the phones over one ear, as I do, so you can record cleanly, yet still be in touch with what's going on outside of the cans.
