JVC HA-NC250 Specifications What's in the Box JVC HA-NC250 Headphones, Carrying Case, AAA Battery, Dual Plug Adaptor, 6.3mm Plug Adaptor Product Description The new JVC HA-NC250 combines outstanding sound quality with advanced noise-canceling and isolation technologies to provide a superior listening experience. 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.
