Thank you,
Depends on the headset.
The Bose QC35 series are the best in this regard, as you can just sit there for hours listening to silence, with NC turned on, even without any bluetooth or corded connection. Be aware that some people will eventually feel a 'pressure' effect on their ears after sitting there for hours, wearing a NC headset.
The Sony 1000xm1, xm2, xm3 series are a bit more complicated. They will power off after a few minutes with no connection. But you can indeed connect the 3.5 mm headphone cable into a phone or PC, and this will prevent the headset from powering off, even with no Bluetooth connection and no sound coming through the 3.5 mm jack. Also, the Sony series is reportedly better than Bose in reducing the 'pressure' effect.
As for other NC headphones, I don't know enough to answer your question.
