The Poor Man's Bose

Bose makes a great set of noise-canceling headphones. If you have $200 to spend, I recommend buying one for plane trips. They do a great job canceling out the low-end noise, so you can hear movies and music better in flight. However, if you're monitarily challenged, try the poor man's noise canceling headphones. They work fairly well (about the same as a low-end noise canceling headphone, like JVC) and are cheap and easy: a pair of regular headphones (not the earbud types) combined with earplugs.

I always travel with earplugs, and I wear them on planes. It really cuts out the engine noise of the plane, but you can still hear voices (which is not really what I am after. I wish I could cut out that chatty lady who invariably sits behind me with her best girlfriend from work on their way to an exciting girls weekend where they have a reservation at a really exciting hotel and they are in the process of making extremely exciting plans for their girls nights out.) Anyway, with earplugs in, nobody talks to me on the plane and it is a little quieter. And combined with regular earphones, it makes a good poor man's Bose.

Speaking of freezing it... plane trips!

How do you get a Go-gurt through airport security? Freeze-it. I have also been known to freeze bottles of milk, juice boxes, and regular yogurts to take as snacks on the plane. If it's frozen, it's not a liquid.
