It stops working, because the latency is too high for the inverse-phase signal to match up with the unwanted incident signal it's intended to cancel.

You could have a low latency digital processor in the phone/soc. At that level, digital is cheap.
Of course the other part is that high-frequnecy noise is hard to cancel. But still Bose does a great job.
You can't have a wireless round trip with latency low enough to work.
