Apple may add health features to AirPods, including enhancing hearing, reading body temperature, and monitoring posture.
AirPods would use motion sensors and alert wearers of slouching and to improve their posture. AirPods Pro already offer features to improve hearing, including "conversation boost" that increases the volume and clarity of people in front of the wearer. Apple wants to add health and wellness features to devices beyond the Apple Watch, where most of their health functions exist today and they're also working on using iPhones to help diagnose depression and cognitive decline.
