Noise Cancelling headphones

A little bit of quiet goes a long way. For any long journey, bet it train, plane, or automobus, you cant beat the quiet of NC headphones. I like the Bose QC20s, as theyre tiny and perfectly portable. The QC25 offer a little more quiet, but are over ear headphones and much bigger. I weigh the pros and cons in Bose QuietComfort 25 Vs QuietComfort 20.
