I swear by these Peltor ones, especially in the duck boat, where it's common to have 18 rounds of 3.5 inch 12 guage loads go off through ported chokes all in about .7 seconds all around you from 6 feet away at most.
They fit REALLY nicely, even with a hat on, which is what they are designed for, actually...no bulky over the top of the head bar...
Trust me, you won't be disappointed. I have used them for 2 or 3 seasons now & they rule. Like any earmuff, they will start to bother you after a while, but I can usually can go about 4 hours or so before i need to take them off for a couple of minutes, but that's a small price to pay.
