Why we like them: Most “fitness” earphones really don’t offer anything that’s much different than normal headphones (besides flashier color schemes), but the lightweight NB439s thinks of every possible workout dilemma. It’s got detachable, easy-to-clean ear cushions, a volume control along the cord, and you can shorten the cord so it’s tangle-free when your MP3 is clipped onto your arm, hat, or anyplace on your body where having too much line can get in the way of your workout.
