A new report claims that Apple is exploring the possibility of using future AirPods to improve hearing and monitor health indicators such as temperature and posture.

Apple is expected to unveil the new AirPods 3 at next week’s Unleashed event alongside the new mini-LED MacBook Pro, but these new features will likely be a long way off.

The source writes that it’s unclear if Apple is developing new hearing aid features for AirPods, or just wants to market existing hearing enhancement features like hearing aids. The best Apple AirPods Pro wireless earbuds come with a “talk booster” feature that helps people hear conversations.

In addition, the headphones will use existing motion sensors to detect the user’s stoop, alerting them to poor posture. Earlier it was reported that Apple is considering adding light sensors to AirPods that can help monitor heart rate, VO2 levels and body temperature.
