I don't shoot, so I don't need hearing protection for that. But I fly, so I always wear a good ANR headset when I do. I also fly aerobatics, and there's one guy in our club who has a Staudacher S-330. It has a boosted AIEO-540 with short header pipes, no muffler. That's a 330 horsepower plane, only 1200 pounds. He wears an ANR headset AND foam earplugs!
