In my younger days, no I never wore them, but I have been wearing them faithfully for 15+ years now. As much as I am around concerts, band practice, etc... it is an absolute must! I have tried the Etymotics and they work great, but I always have a difficult time getting those style in my ears. My ear canals are smaller, so they don't fit too well. I just use the cheapy foam ones everyone here hates. After so many years of using them, my brain has adjusted and I don't mind them at all. I have no trouble hearing guitar solos. When playing live, I usually either us in-ear monitors or wear one in my right ear to protect me from the loud drums!
And I agree 100%, losing my hearing is NOT metal. BTW, I am 40, so I need my ears to last a little longer. ;-)
