Yurbuds' new Bluetooth Sport Earphones connect wirelessly to your iPhone and feature medical-grade soft silicone tips that the company guarantees will stay in your ears. 15 mm drivers pound the sound, too. You can buy them now for $169.99. Also check out the Race Case, an iPhone case with a breathable silicone hand strap - so you don't have to worry about dropping your phone while you run.
Check out the video for more details, and make sure to stick around for the guy who tests out the headphones' ability to stay in place by doing a handless cartwheel.
