memtb,
Not a fan of Walkers electronic (low end) muffs. I bought two pair, only opened one, they did not seem to shut off as quick as my old (low end) Howard Leight's or Caldwell's....
Jerry - the Walkers don't shut off. They're sound compression devices. That's why I like them better than the Peltors I have, which shut off to control the noise. Much easier to have a conversation over gunfire with the Walkers.
