It's a hot day at the range and you're taking a break as the range is clear. Where to put those sweaty cups? Certainly not around the neck or above the ears. A pouch on your kit seems like overkill. How about this handy hook?

The Safariland Hearing Protector Holder is an injection-molded plastic hook that wraps around and clips onto the belt providing a place to hang ear muff style hearing protectors. It can also be used to carry a supply of disposable restraints.

Simple as that.
