Some had asked about the earseal breaking with a rifle cheekweld. I didn't shoot any rifles from prone yesterday, but you can see in the picture that shooting a carbine causes no issues with cheekweld.
I spent last weekend at the Morgantown Appleseed held at lovemywoods'-- shooting from prone most of the 2 days. I didn't get any specific pictures but I can tell you that my earpro was the last thing on my mind. They never failed, became uncomfortable, or got in the way of shooting.
