I use Walkers Ultimate Alpha 360 ear muffs. They have 4 mikes (2 on each muff) for "surround sound", but cut off when my .340 Weatherby with the muzzle brake goes off. I can also hear my guide whispering to me, along with Elk bugles and other sounds. I bought several pair in Kryptek, Camo, and a pair of black. They are usually on Camofire.com for about $75.
