I'll be honest, when it comes to headphone wires, I'm often tangled up. When I'm running, it's not long before my flailing arms come in contact with my pair. Stay-put, in-ear headphones are a must when on a fast run to help me stay on track without having to always reinsert my buds, but lately I've been loving these waterproof, wireless Blue Ant Pump HD Sportsbuds ($111). The Bluetooth headphones come with several different bud sizes — including some with "stabilizers" for intense workouts — to ensure a no-fail fit, and since they're wireless, there's nothing to get in the way of a good run. The best part? The sound quality keeps me, well, pumped, all throughout my workout.
