Summary: I absolutely love these headphones. I work out in them 3-4 days a week, including running and weight lifting and never have had a problem. They stay in my ears which most other ones don't, and the sound is great. Might buy another pair just in case mine ever die!
Summary: these headphones are a model up from the ones i previously use - i cannot fault them as i use them roughly 5 times a week for sweaty 2hr gym sessions, and they still remain with great sound, no tinny noise, and fit very comfortably regardless of what sport i'm doing. i can thoroughly recommend them!
Summary: Over ear clip does work although it can be fiddly to fit- seems best to put in earpiece and then fit clip around ear. Water resistance cable untested- they coped with my perspiration in the gym so far. Cable running through clip is good design feature as it helps keep out of the way. Sound is fine when not in the gym where there's MTV at high volume (does anybody actually listen to that?
