Outstanding sound quality with advanced noise-canceling and isolation technologies. 
Detachable four-foot cable. 
Headphones fold up to fit in included slim carrying case. 85% Noise Reduction The HA-NC250's noise cancellation circuitry includes feedback technology, which constant monitors extraneous background noise to eliminate up to 85 percent. For further isolation, JVC employs a double housing structure on each earpiece, providing an extra sound insulation layer. The headphones' foam-cushioned ear pads add one last layer, not to mention they're nice and comfortable for long listening sessions.
The headphones use a single 1.5-volt AAA battery for powering the noise cancellation circuitry, squeezing about 50 hours of use from a single battery.
Noise Reduction On/Off Switch
For convenience, the HA-NC250's active noise cancellation can be switched off, enabling you to address someone speaking to you, hear announcements on a plane trip, etc.
Great Sound
Eliminating outside sounds is half the job. For the best possible sound quality, these headphone use a 40mm neodymium driver in each earpiece, for high sensitivity and a great frequency response.
Ultra-Portable
For comfort and portability, the HA-NC250s are one of the lightest headphones in their class, weighing just 5.3 ounces. The phones folds nice and flat, for toting around in the included slim carring case.
Also included are the four-foot detachable cord, airline dual plug adapter, and 1/4-inch plug adapter, for use with a wide range of audio and video components.

This review is from: JVC HANC250 Noise Cancelling Headphones - Black (Electronics)
We tried several models of noise cancelling headphones including Bose, Creative Aurvana X-FI, and two models of JVC (this one and the HANC80 model). The Bose and Aurvana X-FI both do an excellent job of noise cancelling and are comfortable. But they are also $300. We just wanted something that did a good job for a few airplane flights a year. We found the HANC250 model on sale for $100 rather than the $200 normal price. We tried them side-by-side with the HANC80 and decided that the over ear model 80's did a better job of noise cancelling. We sent the 250's back and used the 80's on a flight from Seattle to Hawaii. They made it very enjoyable to watch the movie and listen to the audio programs. They didn't eliminate all of the other sounds but it was completely adequate. They were also very comfortable for the entire flight. If you don't want to spend the $300 on Bose or Creative models, I recommend the JVC HANC80 model.
