I ordered these for running because the earbuds I have were hurting my ears. Also, I feel safer knowing I can hear what's going on around me more clearly as I run in a suburban area and like to be able to hear the traffic, etc. I ordered the ones for kids as I am petite, and since they're adjustable anyway, I thought they'd work great, and they do. I feel like they are loud enough and definitely much more comfortable than the earbuds that I was using. They stay in place much better than the ones that hook over the ear. I love them, and my daughter wants a pair for herself too!
