If you’re looking for the best over-ear noise-cancelling headphones to make travel on a plane, train, or car a bit quieter and more relaxing, the Bose QuietComfort 25 is the pair to get. We spent more than 30 hours narrowing down a field of 20 different models in order to find that the QC25 offers the best active noise cancellation of any headphones available, plus it’s comfortable, lightweight, and able to fold down into a compact carrying case. This model isn’t perfect—the sound quality is decent enough, just not spectacular—but the main purpose of buying these headphones should be for their noise-cancelling capabilities. (If sound quality is your absolute most important criterion, see our $400 headphones guide instead.)
