Apple Inc. is studying how it can morph its AirPods into some sort of a health device. This could include having them double as hearing aides, an in-ear thermometer and even body posture warnings. The tech-giant already dominates the global Bluetooth headset market, generating an estimated $12+billion in revenue from this market in 2020. Apple has already made quite a splash in the health device market with its Apple Watch, and is also looking at using iPhones to help diagnose depression and cognitive decline.
