Thanks, everyone, for your input. My experience is just like SPYDEZRA described. Planet Fitness and all. Today, I plugged into my iPod instead of the jack on the treadmill. That seemed to work. It's taken me a long time to find ear buds that stay in. I really like these ones. They are Ironman for women. So, for now, I'm blaming the treadmills at Planet Fitness. LOL.
I am the creator of my wellness.
