Hey guys For rehearsals, or rock concerts the normal earplugs doesn't work good if you want to enjoy the music. I've been searching the internet and found some earplugs that attenuate in a very flat response all the audible spectrum. I want to take care of my ears and enjoy the music at the same time. have anyone of you guys used this kind of earplugs? any suggestion for brand or type? I found these ones. http://earplugstore.stores.yahoo.net/er915and25pr.html http://www.earinc.com/p2-specialty-musician.php thanks for your support!
