Sennheiser
The constant low rumble in an airline cabin ruins the clarity of satellite TV, your portable DVD player, or any MP3 player. In-flight entertainment is where noise-canceling headphones make the biggest difference. Now, Sennheiser's PCX300 with a collapsible headband makes the phones easy to squirrel away in the supplied travel case. The PCX300 actively reduces rumble using two supplied AAA batteries in an outboard battery pack (below), but unlike some other noise-canceling headsets, it can be used for regular listening even when the batteries are exhausted. Price: $220. sennheiserusa.com,
