It isn't a software issue if it happens on both his iPad and his iPhone. Those are two different players. Does anyone know if head tracking panning is accomplished in the AirPods or in the iPhone or iPad? If it's happening on both his phone and pad, it's clearly a fault in the AirPods. If it was me, I wouldn't waste time. I'd head straight over to the Apple Store and ask for a replacement since they're so new. If there's no store near, call Apple and arrange an exchange by mail. Exchange them and the problem should be solved. Wait for someone to confirm and you may be waiting forever.
The people who are saying they have experienced it too are describing spacial audio head tracking. They have it turned on while they're walking around the house. That isn't a bug.
