Query: Decent sound, terrible as sports headphones

The sound is decent. But the phones are terrible for sports, especially for running. They won't stay in. They are constantly falling off, pulling away so that you only hear through one ear, and the clip only worsens the problem. So I'm still on the hunt for headphones that won't fall off during a workout. These aren't them.
