MJ,
I just picked up a pair of Caldwell or Cadwell over the head ear protection. It has the mics on it to pick up sounds less than a certain decibel and block out the ones that are more. I haven't used them yet, but while working at the recent Black Eyed Peas concert in Des Moines, one of my supervisors had a pair on and I asked him about them. He said they worked pretty well for him and he could block out the ridiculously loud bass they had at the concert, but he could still hear us talking to him. They cost $35 at Bass Pro. Work good for the little bit I've used them, so hopefully they work well while out doing a little upland hunting.
