I have a set of the ProEars that I used whenever I go to the range. They have worked so well on the range that I have used them hunting.
They protect my hearing very well and I am grateful but must agree with Graybeard about all the noises you can pick up with those things turned on. Voices and gunshots are muted; the sound of your scratchy beard on your shirt collar is not muted, nor is your stomach rumbling, or the hair on your head (fer sum ov us...) rubbing against the inside of your hood. Not being able to wear my favorite hat on accounta the earmuffs (is OK), I just got a bigger hat...
Unfortunately I am almost afraid to move when I am wearing them and waiting or watching an animal approach. I know whitetail have hearing 7 times more acute than humans so how could it possibly be that all the noise I make when I turn my head doesn't scare them off or at least alert them?
Any of you ever heard that 400 lb squirrel crashin' through the woods and the sound of one Whitetail approaching makes me think of Paul Bunyun's giant blue Ox, Babe. And please, fer da luvagawd, don't ax me to walk anywhere with those things turned on - the sound of one of my feet crashing down through frozen grasses must carry for at least 20 miles. Just about the funniest thing I have ever seen is two old fat men, me and my huntin' buddy, tryin' to tip-toe through the frozen fields so as not to make any noises when going up to our stands, while wearing those ProEars. I never imagined the sound of frost crunching was anywhere akin to the sound of steel I-beams being ripped apart. Mikey.
