I like the sleep ear plugs; they're silicone plugs that are moldable. So they don't tend to extend out so much, or over-fill the ear like buds do.

I was at a festival a year back and unfortunately our camp was near a minor side stage which was running a daytime talent show. I wanted to take an afternoon nap. The sleep ear plugs + noise canceling headphones dulled the moderate noise down to almost nothing.
