In the “White Noise” section of the app controlling Anker’s Soundcore Sleep A20 earbuds, under the tab containing all the available “Life” sounds, there’s an “Airplane” option that will, as the name suggests, play the rumble and hiss of an airplane through your earbuds, just like you’re in a real plane.

What? Aren’t earbuds, earphones and headphones meant to cancel out the sound of airplanes, trains and spaceships when you’re travelling in those vehicles, rather than play those sounds back to you? (And, yes, “Train” and “Spaceship” are also white-noise options in the A20 earbuds.)
