A:AnswerThey are wireless (Bluetooth) only but most new airplanes don't have a plug in system anymore anyway. Other than that, they aren't noise cancelling but technically you can use them with your phone or tablet.
A:AnswerThese Headphones will connect to anything that uses Bluetooth Connection / Pairing. I use them with my Insignia FIre Smart TV to watch TV at night so as not to disturb my wife while she is sleeping, also use them while playing video games as well.
A:AnswerYes. I have a amazon firestick and these headphones pair up to the Bluetooth on it. Yes there are volume buttons on the headphones to control the volume
