As LG writes in its press release, "Because of the unique physiology of the ear, wearers can get more accurate health and fitness metrics with LG's Heart Rate Earphones than with other devices, especially when engaged in physical activity." Let's hope this means the Heart Rate Earphones can provide continuous, accurate, real-time heart-rate data during actual exercise. Competing products can't make that promise.
Oh, and of course: The Heart Rate Earphones also promise "excellent sound." We'll be the judge of that as we test one of the most novel wearables to launch this year.
