I use my ears as another hunting tool. There have been so many deer that I heard before I ever saw them. If your ears are plugged up with music you will surely have deer sneak by you and you will never see them. I never even put ear muffs on my ears or pull hats down over them since it will impair my hearing. Listen to that ipod before and after the hunt. One needs to utilize ALL their senses when one is out hunting just as the deer do to avoid us.
