Sony MDR-NC6 Noise Canceling Headphones

Small enough to keep with you at all times and ideal for achieving peace and quiet in planes, trains, buses, and cars, Sony's MDR-NC6 noise-canceling over-ear headphones reduce perceived outside noise by more than 70 percent (up to 10 dB at 300 Hz) so you can hear musical nuances against a quieter background. The headphones' noise-canceling circuit senses outside noise using tiny, built-in microphones and sends an equal-but-opposite canceling signal to the headphone drivers, effectively blocking solid-state (continuous) noise from 40 to 1,500 Hz. It's especially effective on noises like air-conditioning systems, freeway rumble, and airplane engines (from a passenger's perspective).
The switchable noise-canceling circuitry runs for approximately 30 hours on a single AAA alkaline battery. When noise canceling is off, the headphones continue to function for standard music listening (and with slightly better sound quality). The headphones' neodymium-magnet diaphragms deliver powerful sound. The headphones and their swiveling earcups fold for easy storage, and a special supplied adapter facilitates use of the headphones with an airplane's audio system.

Customer feedback:
1. After 8hrs on the plane the past few days, i need to purchase a second pair for my wife. for the price, the performance is amazing. My only complaint (if you can call it one) is after a few hours they seem to press kind of hard on my ears. Sound quality is fantastic. works well with my portable dvd player.
2. I didn't realize over the ear headphones could sound so great. I tried these for the first time on flight to the west coast. They did a great cancelling out the noise on a loud commuter flight and were perfect for the jet flight. I could finally enjoy a movie on my laptop without the constant background noise from the airplane. Bass, midrange and trebble were clear and crisp. For the price, you can't go wrong.
