Your armband suggestion went right over my head. Please explain?
The armbands were a reference to the movie, where the members of Charles Mott Society were given armbands at the checkpoints for stopping cigarettes from getting inside the town. Their leader had asked if they could wear armbands and Dick Van Dyke said right back to him, "sure!"
...hearing protection for those who are exposed to lots of gunfire (for instance regular attendees or workers at gun ranges)...
But they are notorious for ruining the accuracy of your shot. Why would you want to use one at the shooting range when you can use perfectly good headphones?
