Re: Quality e-muffs.??
If you want good hearing protection, forget about the electronic muffs. Even the best have moderate sound attenuation.
The highest rated muffs are by Howard Leight at 31dB. For really loud boomers, I also use their new earplugs rated at an amazing 33dB.
With both on, the loudest muzzle brake boom is quite tolerable - actually comfortable. Has made long shooting sessions very pleasant.
In a hunting situation where you do need some hearing, I will be using my new Peltor 6. Pretty good microphone system and moderate sound attenuation. Good enough, that I won't go deaf after one or two shots at game. Very compact and light.
