AWESOME! AWESOME! pure effin epic win... and nothing BUT win. I was looking for something that would tackle the annoying ringing and muffled hearing after a day at the range. I found the surefire EP6. I didn't know what size I would need, so I bought all 3 sizes. Small would be good for a youngster. Medium would be good for anyone 18 and up and in that age range, some people with larger ears may find the large size to be necessary. So basically, these things allow me to hear people speaking AND block out the *bang* of my AR. It sounded like a hand clapping. It was amazing!! I let my buddy use the large ones and he agrees. No after-range hearing issues reported. HIGHLY recommended!!
