TechRadar has reported that Apple has filed a patent for the next iteration of the Air Pods that could mean the little wireless earphones become a fitness tracker in and of themselves.

The patent shows that the Air Pods will contain biometric sensors. While bio-metric sensors in headphones aren't a new proposition -it is exciting to see Apple is working on this technology.

According to the patent found by Patently Apple, the sensors aren't just limited to simple heart-rate monitors either.。It appears that there are plans for EKG sensors that monitor the electrical activity of your heart, impedance cardiograph sensors, and more.
