Damaged my ears - Pro Ears Pro Tac 200 NRR 19 Hearing Protectors

I purchased these muffs to shoot .308, and .300 WM. I took them to the range. The gathered ambient sound was quite good. Then I pulled the trigger. Wow! It hurt. Not being too smart, I shot a few more times. Ouch! I am not sure, but I think the rifle report was being magnified. For a week after, my hearing was effected. It may still be now. I called OP, they were off warrantee, so they sent me to Pro Ears. Pro Ears said I should have purchased the $300 pair. I'm not too happy to say the least with either outfit.
Pros: none
Cons: Do not work
