I recently got Bose QuietComfort 20i for my trip from Europe to Australia. It was expensive, but so worth it. That constant humming noise on the plane usually makes me incapable of doing anything. With these earphones—you flip the switch and the magic happens. Especially on the flight from Singapore to Perth which was very smooth (no turbulence) it felt like just sitting in a room and listening to music. Watching movies on the plane also became much more enjoyable, with headphones offered by airline you need to turn volume almost to the max. You need an adaptor for airline headphones jack though.
