Noise cancelling earphones really work
At the duty free store I bought these noise cancelling earphones for the plane. It's not perfect, but it does a great job of cancelling most of the noise. Now I walk around town with these things (I know, I look like a dork), but it's wonderful not having to crank up the volume to 11 just to hear podcasts. The batteries last a very long time (weeks for me) unless I forget to turn them off.
