This is my second pair of these headphones. They lasted about a year (5 days a week use) before I needed to buy new ones. I like the twist and fit action that keeps them in my ears when I run (even if I get really sweaty!) The only thing I didn't like was how flimsy the cord is,(I used the clip and if you slide it too much it will split the casing of the cord.) And the ear buds were a bit hard to get used to in the begining...Other than those two things I would buy a third pair when these go out!
