You should be wearing ear plugs! Hearing damage cannot be fixed once you have it! You probably don't have any (or much, because everyone has some) yet, but you must protect your ears!
It would really suck, if it ends up so that you can barely hear all the great little nuances of music, just because you didn't take the time to wear ear plugs! Even at concerts, wear them... if anyone tells you that it's "not cool", they are morons and you shouldn't listen to them! They'll be real cool when they can't hear in 5 years!
