Any idea which one of these is the best?
Any real world tests with QuietDose™ In-Ear Dosimetry Measurement system been used to compare these muffs?
Some thoughts:
Pro Ears
I know pro-ears has the best rating but that could be just marketing. I've seen it done all the time in other industries. Over promise and under deliver on performance.

Howard Leight put an impressive amount of resources into their website. The VeriPRO and QuietDose™ In-Ear Dosimetry Measurement system make me wonder if anyone has used those systems to test real world applications at the firing range. With that amount of resources focused on hearing protection you have to wonder if they aren't at the top.

I think the navy uses these so they have to be good right? I'm not sure how to read their attenuation ratings yet. SNR, H, M, L??? They seem to be the only muff that has double walls. I assume the Bull's Eye is better.
