JVC has just announced there top of the range 'noise cancelling' headphones, to rival those4 of Bose. The HA-NC250 should be available in early August for $199.95. These headphones weigh in at 5.3 ounces and JVC claim that they can eliminate upto 85% of background noise using their adaptive feedback technology.
The HA-NC250’s noise cancellation circuitry includes feedback technology that constantly monitors the noise cancellation process. As a result, the headphones eliminate up to 85 percent of extraneous background noise. To further block noise, the HA-NC250 offers two JVC innovations that help isolate the listener from outside sounds. First, each earpiece employs a double housing structure for an extra sound insulation layer. Second, JVC developed a new technique for attaching the headphone’s smooth memory foam cushioned ear pads to the housing that helps isolate background noise. The smooth pads also enhance comfort. These sound isolation features, for which patents have been applied, are especially important since the HA-NC250 can be used with the active noise cancellation switched off.
The headphones folds flat, and your $199.95 gets you: a slim carrying case, a four-foot detachable cord, airline dual plug adapter, and ¼-inch plug adapter for use with many home audio and video components, as well as the headphones.
Powered by a single 1.5-volt AAA battery, you should get around 50 hours of use
