Hazardous noise exposure has a cumulative effect on your hearing throughout your life. 1 shotgun blast may not be noticeable now, but after a while you will have hearing loss.To me it isn't worth it, I try to always have hearing protection with me.
I use Howard Leight Impact Sport Electronic Earmuffs, shooting, hunting, yard work and sometimes around my wife. Mabe others on the market but I've found these the best for me and they take AAA's.
