Not to mention they may spare your hearing in the long run. I didn't wear them for a long time until some festival friends recommended V-MODA Faders. They're the first ones I've tried that left the sound clear enough that I don't mind wearing them.
I also bring a supply of the foam ones for sleeping. Those, plus a good eye-mask and some over-the-counter Benedryl (Acrivastine in the U.K., I think?) and I can usually get a decent seven hours of sleep after a proper night out (and with little in the way of side effects).
