I’ll start this off by saying I am by no means a headphone expert. However, I’ve really enjoyed these headphones for exercise! They stay in my ear very well. They’re easy to use and have good connection with my iPhone. I appreciate the cord attaching them because knowing me, I’d lose one if it didn’t. It took my ears a couple of runs to adjust to them, but it wasn’t painful by any means! Easy buttons to pause or change songs/volume. The charging cord is short, so I use an extension cord.
