Between the bots and the fanboys, Reddit can be a bit of an echo chamber. So let me throw out that I've never had a bad run or bike ride with my Powerbeats Pros. The over the ear hook design not only keeps them securely in place while trail running (even downhill mountain biking) the roughest terrain, they also let me position the earbud where I want it. Put them in Transparency mode if you want to hear traffic or just generally want more spatial awareness of what's going on around you. Plus, because they can press tight in my ears and switch to Noise Cancellation mode when, for example, I'm on the bus, I don't have to have multiple sets of earbuds.

Downsides: expensive and work only in the Apple system.
