I was gifted a pair of these Bose headphones and after traveling with them several times I now absolutely swear by them. On the planes the noise cancelling feature completely blocks out the engine hum and the quality of the speaker when plugged into a iPod or iPhone is amazing.
Here's the product description: Slip on a pair of QuietComfort 2 headphones and hear your music come alive. Decades of Bose research combine with our Acoustic Noise Cancelling headphone technology for outstanding audio performance. This award-winning technology electronically identifies and dramatically reduces noise while faithfully preserving the music, movie dialogue or tranquility you desire. The TriPort acoustic headphone structure also delivers our best headphone audio performance in a compact and lightweight design. Listening to your favorite music, you may even forget you have them on. QuietComfort headphones were specifically designed for airline travel, but owners soon told us how much they enjoy using them to listen to music in other places: on buses and trains, in the office, even at home. We enhanced the convenience and portability features of QC2 headphones, making them even easier to enjoy in a variety of environments, without disturbing others. Whether you take them on a trip or to the office, today's QC2 headphones fold flat and store easily in their slim carrying case. To fade background distractions and enjoy peace and tranquility, simply turn the headphones on. To add Bose quality sound, attach the included audio cord and connect the headphones to a portable MP3, CD or DVD player, laptop computer, in-flight audio system or home stereo. The latest generation of Bose QC2 headphones provides even better audio performance with greater clarity of high-frequency sounds.
