From the Manufacturer

Highly portable, the Sennheiser PXC 250 II noise cancelling headphones allow you to take off and then lose yourself completely when flying. Thanks to high-performing neodymium magnets, the PXC 250-II delivers a powerful, detailed sound with a wide frequency response, plus it's equipped with NoiseGard to screen out intrusive ambient noise.

NoiseGard technology cancels up to 80 percent of droning, fatiguing airplane or bus cabin noise without added bulk or size. They are also equipped with a convenient in-line volume control which enables you to adjust playback volume even when the music player is stowed.

They offer a closed, supra-aural design that provides for excellent passive attenuation of ambient noise. The newly-improved battery pack requires only a single AAA alkaline battery, and it lasts up to 50 hours--more than enough for a flight from Tokyo to New York (even taking delays into account).

Suitable for all types of modern music, it provides detailed sound reproduction with a slight emphasis on the bass. Other features include a steel-reinforced headband for high durability and included carrying case.
