@WRKY933 good tip. I haven't had that exact problem but I have had a similar problem. When I'm at the park throwing the Frisbee for the dog, I keep the radio on my belt just over my back right pocket. Sometimes as I walk, the volume gets turned down so I can't hear anything. The O-ring should help with that as well.
PS I think Harbor Freight is where I got my box of O-rings.
