Personally, I have never used hearing protection on a hunt. One shot and its over. At the gun range, muffs "Howard Leight Impact." However when your hunting when the situation presents itself, its fast and there is little time to get hearing protection in. However, I do bring with small disposable plugs that fit well. Hiking and moving around your not going to want anything in your ears.
