I have never had my ear ring from my own gun. I think it would be unsafe when walking on uneven ground, hunting in early sept badlands rattle rattle, I think they would be more unsafe then safe. You have to have all your senses working imo while hunting. Your ear forms some type of sound pressure just like when you dive.
The only time i had my ear blown off is target practice when i forgot to pull em down after reviewing target from the aholes cannon next to me. It did some damage.
