Summary: Junk junk junk junk junk. I bought these with one expectation. That they would stay on my ears. They do not. I can't run for more than 2 minutes without one of them falling out. My cheap earbuds stay in better than these things.
Pros: If you like running angry and frustrated, these provide great motivation to fuel your workout.
Excerpt: Do not buy these earphones unless you intend listening to your music sat down or while remaining perfectly still. Used them with both ipod and mp3 player, each time the music was crackling and breaking up. Had to keep adjusting the connection to my device.
Excerpt: I was satisfied with these headphones until they stopped working, after less than 6 months the right headphone started cutting out and within a week stopped working entirely. Very dissapointed with this product.
Excerpt: I'm a runner, and have been looking for the perfect pair of headphones. Unfortunately, these are not them. I read about these headphones in a fitness magazine, which stated that they will not move during any athletic activity.
