Accelerometer drift is a hard problem. You can experience it with VR headsets that have no base station, like Playstation VR. They require re-calibration every 10-30 minutes or so. I assume that the iPhone/iPad is constantly re-calibrating user orientation using the camera and depth mapper. I imagine two ways that Apple could make AirPods Max work with Apple TV: 1. Add a camera to the Apple TV. Some people would be uncomfortable with this. 2. Add an orientation base station to the Apple TV and add receivers to the headphones. This will increase weight, cost, and power consumption (battery weight). It's possible that Apple already added the sensors. Has anyone done a teardown to look for orientation signal receiver chips?
