These are pretty good. Sometimes they don't immediately work, which is frustrating because the one light and two buttons don't give you a lot to work with. However, when they work, they do a fine job. The earbuds are the only ones I've ever used that stay in my ears when I run. The sound quality is pretty mediocre, but not having to re-insert my headphones every 10 steps is worth the sacrifice.
