Noise-cancelling headphones are basically essential on planes, but a Transparency Mode makes it easy to hear what the drinks options are…
That’s known as Hybrid ANC.

It will mean it’s harder to hear your music than just with ANC turned on.
And not all Transparency Modes are created equal!
How can I get Transparency Mode?
