These are the BEST thing ever. I love going on a run or a bike ride with these bad boys in. They stay put and come with the sport clips for extra stay-in action. The sound quality is very good. It's a little sub-par on the bass, but I'm guessing you wouldn't be able to get super bass out of anything with bluetooth. I highly recommend these if you are on the go, like to work out, or just hate tangled up cords.
