Not for any sort of activity
I returned these for headphones that are actually built for humans. I ran about 10 steps with these on and they started to fall off. These would be great if you had nothing else to do with your hands except hold them on your ears. If you couldn't figure out, I rate fitment a 1. Overall sound would be much better if you stuck your head in a vice to keep pressure on both ears. Found retractable cord nice, but too sensitive, with any kind of movement it tends to retract randomly without pushing the buttons. Stylish yes, functional absolutely NOT!!!
