A set of HL's are great shooters ears, we rock em plinking... But for hunting, you can't beat a good pair of Pro-Ears. They use cr123's, but I've had em last five years on a battery and I hunt a lot. I also have a few pair of the Caldwell electronic lightweight muffs I loan out to accompanimg shooters. Good quality stuff, got em from Marks Prairie Wing for $15 a pair.
