Ear-o-smart is introducing a new segment in the wearable electronics market, the first smart earring. By combining fashion and electronics, you can now easily monitor your activity level without compromising your looks. Ear-o-smart connects to your smartphone with Bluetooth 4.0 wireless technology and allows you to monitor a wide range of fitness data such as heart rate, calories, and activity level. The wearable market is expanding quickly, but the problem is that your options are very limited; most fitness monitors are limited to wrist based electronics.
