I have had a hearing problem my whole life, perforated ear drum on right side and tubes several times on both ears as a child. I never knew what I was missing. Elk hunt earlier this year in September, I couldn't hear elk bugling in the distance. Return to whitetail woods at home but bought these to mitigate my hearing issue. "Game Changer"! I heard a buck rubbing a tree at 70 yards. Killed him and then another in Ohio. Would have never heard either of these deer without the new ears. If you have any hearing issues don't hesitate to try these out. You won't regret it!
