In-ear earbuds for cycling

I don’t use earbuds on the road, but for the last 2 years or so, I’ve been using Beats Fit Pro earbuds. The sound is good, and the noise cancelling is good. They have, however, occasionally fallen out. I think I’m going to switch to the Powerbeats Pro 2 simply because they have a thin piece that wraps part way around the ear.
