A lot of people like to monitor personal stats such as their heart rate while exercising, plus they also like listening to music at the same time. Usually, doing both involves wearing at least a couple of devices at once. iRiver's new On audio headset, however, plays back music and gathers biometric data ... in both cases, through the user's ear.
Using technology developed by PerformTek Precision Biometrics, the On reportedly "monitors more real-time fitness data from a single source than any other personal monitor." This data includes heart rate, speed, distance traveled, aerobic fitness level and calories burned.

All of this is obtained through a sensor module in the right-hand-side earbud, that uses infrared light and an accelerometer to analyze blood flow and physical activity.
That data is displayed on the user's paired iOS or Android mobile device via an accompanying app, which can be used to track progress and create a personalized fitness training program. When used as a training aid, the app will deliver voice prompts to the user as they're exercising, letting them know how close they're getting to their goals.
Needless to say, the On also allows users to listen to and control playback of music being streamed by Bluetooth from the paired device. They can also use simple controls on the headset to take phone calls.
The iRiver On is available now, for US$199.99. It can be seen in use in the video below.
