Hi JBmusic. The answer you have seen is wrong! You can switch the Elite 700 on and off, and use its noise cancelling function at your wish, even with cabled connection, and without Bluetooth being active. Actually, you can use it as a pure NC device, without any music at all. It is true that you need to have Bluetooth connection to a telephone to use the My Harman Headphone app, where you can control many functions, but in the app, you can pre-set the multi-function button to act as an ON/OFF switch for the NC function (or alternatively Awareness ON/OFF) ahead of your trip, so you do not need to have the app open when using the headphone in the plane. Whether audio is fed through a cable into the headphone or not does not make any difference.
