It stays on your ears and can work great.

I use it for swimming laps with books on tape. If you can get the ear buds positioned perfectly....it is a DREAM and the laps melts away. It does take some effort to find that place. To the sellers; I wonder if you raised the volume, it might overcome the sealing issues. This being said, the ear buds works better than my daughters i-pod buds in the water.
