Apple AirPods are the world's first TWS that changed the wireless audio product market for smartphones. Now after competitors offer various better iterations, Apple is still looking for a way to compete. They have been awarded a patent for AirPods with a screen and, most recently, are serious about developing AirPods with a built-in camera.
This camera is said to not be for recording photos or videos, but is for an infrared sensor. It is said to be the same infrared sensor used with Face ID. The actual function of this sensor is still not revealed, but it is said to be for a more realistic spatial audio experience. Its use may also require Apple Vision Pro.
In addition, this sensor is also expected to bring support for gesture control over the air by detecting hand movements. Anyway, let's wait for more details if these AirPods become a reality.
