That's kinda why I was interested in noise-cancelling cans with a "transparency" mode, able to feed back into the 'cans as needed/desired.
Haven't had the occasion to even try one though.
In any case, ANC is best at cancelling out constant background sound, and is less effective at short bursts of noise (crashing sound, another commenter mentioned crinkling candy wrappers, etc.). At home with level 10 I can't hear anyone knocking at the door, but construction noises still get through if you don't have any audio playing. Level 5 resolves the door issue but makes the construction worse :(
The voice feedback is a different feature which activates when the mic is active, so you can hear yourself. Not sure how that compares to what the 1000XM2 does.
