ANC isn’t perfect. ANC leaves a noticeable low level of noise from imperfect sensing, processing, and cancellation. It’s quite easy to imagine that this could be detrimental (as compared to passive noise canceling).

It’s probably not as good for your hearing as an equivalent level of passive NR. When I fly long trips, I notice that my hearing is slightly impaired for a day or so. There could be a lot of confounding factors there, of course.

That's not added sound, though, that's a portion of the original sound that just didn't get cancelled.

The likelihood that it’s 100.0% original sound and 0.0% imperfect opposing waves is extraordinarily low.
