I tried these on at the store and they seemed great. I guess I should have read the reviews here more before buying them. I bought these to use for trap/clay shooting and was not very happy at all. #1 they do not block the sound very well, #2 there was a slight delay until they shut off loud sound, and when I turned them up I heard a faint hissing. Being used to foam earplugs, they felt & sounded a lot different. I could have gotten used to all the shortcomings if they fit better, meaning, when I mounted my shotgun they would hit on the stock. It was very distracting, even if I could have adjusted the fit or my mount slightly, it was too distracting to be worth dealing with. I didn't even shoot a full line, maybe 1 or 2 posts, max and took them off & sent them back. Thank goodness Amazon has an excellent return policy!
