I’m sure Android and iOS could add some AI feature to let some specific noises in the headset when needed (baby cries when enabled, smoke detector alarms, bike/car bells, etc). Simply stop the music for the duration of the specific noise and replay it. That would be a cool use of AI.

So you don't even need Android or iOS for this feature and it's been a thing on certain headsets for a while; both my Sony headphones and buds do this.

It also has an integration with the phone which can add GPS awareness but it works fine without it in my experience.
