A:AnswerNo. The noise canceling is nice and all, but the large foam walls only do so much to stop sound leaking. If I were you, I would get a separate pair of Bluetooth headphones that you can run under a pair of specialized noise canceling headphones.
A:AnswerYes, you can use these headphones wired too. There is a spot on the right ear near the volume switches where you can plug in a cord. I also use my iPhone charger adapter for charging these headphones too - just plug the USB cord in that came with the headphones. They charge fast too.
