I don't use either on a plane, can't sleep with facemasks, and I hate things in my ear. However it's not the noise. A plane rarely has turbulence - you can board a plane at midnight in Singapore, put the bed back after a nightcap about 2am singapore time, get a good 8 hours, and wake for an early breakfast, with no disturbance as everyone else is either asleep or sat in their seat. On a sleeper from say London to Aberdeen you are woken by various stops and the noise on the platform (Crewe, Preston, Carlisle), and then again by shunting and banging at Edinburgh as trains are coupled and decoupled.
