+1 on protecting your hearing, mine is affected and I have medium tinnitus in the right ear which can be a real pain.
I use ear muffs for practice and just messing around but for hunting they are a nuisance. So I went the full hog and bought a pair of Starkie nu-ear electronic hearing aid type ones, the price included having a hearing test .so they can tailor them to your hearing and molded to fit my ears. I have to say they have been great (4yrs now) and the volume is adjustable. I can hear everything, even mozzies and when you fire they shut off the dangerous part above 85db, but you still hear the rifle fire properly and they are comfortable all day. They cost me $650 altogether but what price the remaining part of my hearing, I couldn't imagine going hunting without being able to hear whats going on around you!
