Normal earbud headphones aren’t much cop if you’re a runner: sweat and rain can leak into them and they can fall out of your lugholes. Not the case with these sporty in-ears from Sennheiser, which are designed to stay locked in your shell-likes no matter how much bouncing you do. They’re water resistant, and there’s even a reflective strip on the neckband. Oh, and the sound quality is peachy for the price.
