I bought these for running because I'm tired of my earbuds falling out all the time, but these are about the same. They fall out just as much as my cheap-o ones, if not more. If I hadn't bought them cheap on S&C, I would return them.
Otherwise, they sound fine. They just didn't actually "fix" my problem. Also - they don't say which is for the right and left ear, but I found that they fall out equally no matter which way I put them in. I will be forever indebted to whoever actually solves this problem!
