I just got a pair of the EP4's in and I can say that they don't attenuate as much sound as my Howard Leight Airsoft plugs, but they can fit under my muffs a lot better. I wouldn't want to shoot much more than a 308 with just these. Also the Hock's Noise Breaker seems gimicky. I haven't tried them with the stoppers out.
So, what are you're guys' thoughts on them?
