In my suitcase: Bose Noise Cancelling Headphones aka a hug for your head

Shhhh: Zen vibes on route to Hong Kong

Shhhh: Zen vibes on route to Hong Kong

These babies are the first thing I pack for any trip - they're not cheap but worth their weight in gold for regular flyers. 

Flick the switch and everything changes as cabin noise/crying babies/plane engines/droning business types/the husband (kidding!) are muted and you're left alone with your music and movies, or just simple peace and quiet.

The sound quality and soft leather ear cups cocoon your head and ensure zen vibes whatever is going on around you - so they're great for commuting too.
