The problem with most Bluetooth sports headphones is that they often come off your ear due to the bouncing of the main wire connecting the two ear pieces. Urbanears solves this problem with Stadion, their newest headset designed with a stretchy coil that adapts to the shape of your head, and EarClick technology that ensures the earbuds stay in place in your ear. The controls include three buttons conveniently placed in the back, and built-in reflector strips add visibility during night time workouts.
