A good pair of in-ear phones: It's impossible to overstate how valuable these are. Not only do they sound better than your stock earbuds, they dull the chorus of engine sounds, snores, baby cries and not-as-subtle-as-your-seatmate-thinks beanfarts nearly as well as those Bose noise-canceling phones some airlines hand out in first class. As a bonus, you can sleep comfortably in these. Ultimate Ears MetroFi 170s are nice, clear and bassy for about fifty dollars, while Shure's next-level SE210s can be scrounged for under $100. $50 for the UEs, $90 for the Shures.
