We all know they're handy, we all know they don't block 100% of the noise, especially if the music is booming in your bones.
I use mine on and off all year at home, and realized I had to learn how to sleep in them. So if you've never slept with your earplugs in, try it a few times at home.
I use the basic crap yellow ones. Mine are getting crunchy after five years, so I'm looking at replacements. I have some nifty conical neon foam ones, but hey, don't these things come in sizes? I must have small ears, I needed to trim them down lengthwise or they catch on my pillow. I've yet to find the molded plastic ones which are small enough for my tiny head.
And you know those cool mint tins which make great ashtrays? They also make great earlplug containers to stash in your tent. Keeps the little darlings less dusty. I mopodged mine, it has cats on it (shut up) and sits beside my bed. How Martha of me. Oh, and don't use the same one for ashes and earplugs, bleh. Unless you're using your ciggie butts as earplugs, which I guess wouldn't kill you, but again, bleh.
I'm beginning to wonder if my new earbuds might do the trick, I can't even hear my freakin' home phone ring with them in, and I play my music really low. skullcandy, local utah company, if anyone is interested.
These are not my fuckos.
