Try this.

For those who are having trouble keeping the wep200 in your ear, rotate the rubber ear piece until it is at a 45 degree angle. Keep experimenting rotating it downward. The circle hook should point left for the left ear and right for the right ear. I was ready to return it as I could not keep it in my ear when I studied how is sat in my ear. It now stays in. Yay! I guess my ears are shaped wierd. Hope it works for you, too!
