Interesting article on how wireless headphones became augmented reality devices. Those devices are changing our behaviour: notice for example how people keep their AirPods on when they are talking to others.

By not having to look down at a screen, those wireless headphones create a soft but recognisable barrier and efficiently communicate that their wearers are elsewhere.
