"Sony has a winner with its MDR-AS50G sport headphones: They're lightweight, they fit securely, and they sound good indoors and outside. Their in-ear design is definitely geared towards fitness nuts rather than commuters; they don't block out a whole lot of sound, which could be a plus or a minus depending on where you work out. The low price ($49.99 USD) is a big plus, since we tend to burn through exercise headphones faster than we burn through calories."
