Because of the unique physiology of the ear, users can count on health and fitness metrics with none of the inconvenience of chest strap measuring devices. The HRM Earphone Heart Rate Monitor continuously monitors a full range of data (including distance, calories, steps, 3-axis accelerometer direction and more) in virtually any weather condition. You’ll be amazed by the rich hi-fi sound. And you’re sure to appreciate the built-in mic for phone calls on the run.
