Gear: Sound systems to tune up workouts
Music may be the ultimate performance-enhancing drug. It makes long runs shorter, big hills smaller and hard stuff easier. In fact, studies have shown it can speed your warm-up by raising your heart rate, motivating you to move faster, even enhancing your coordination. On the other hand, wearing earbuds can be dangerous — and illegal — for cyclists and runners because they can seal out ambient sound; in fact, Florida and Rhode Island prohibit headphone use in any vehicle; California, Maryland, and Delaware legally limit their use to one ear. Here's some innovative, sports-friendly sound systems that either get around those legal limitations or stay in place better, making them safer and more convenient ways to feel the beat.
