The new JVC HA-NC250 combines outstanding sound quality with advanced noise-canceling and isolation technologies, for a superior, uninterrupted listening experience.
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.
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.
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.
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.
