Audio-Technica ATH-ANC7 QuietPoint Headphones

There are a lot of options out there for noise-canceling headphones, but when they drown-out 85% of environmental noise without the radio on, you've found a winner. The Audio-Technica ATH-ANC7 Headphones ($135) offer noise canceling paired with 40mm neodymium drivers for great sound, as well as a detachable cable, carrying case, and airline adapter. Unless, that is, you want to listen to that crying baby three rows up for the entire flight.
