Whether it's a crying baby or someone with a persistent cough, it sometimes feels like your flight goes on forever when there isn't a moment of silence. So, if you don't have a pair of noise-canceling headphones, you should definitely pick one up before your next flight. You'll be able to sit back and relax, regardless of the chaos around you. Rest is much needed when traveling, and noise-canceling headphones really do make that happen.
Everyone on a plane values peace and quiet, but there isn't a way to control who sits around you, thankfully, noise canceling headphones can really help guarantee relaxation when it's needed.
