JVC HANC250 Introduction

JVC HANC250
Introduction

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. For the best possible sound quality, the new
headphone uses a 40mm neodymium driver in each earpiece. For comfort and portability, the HA-NC250 is one of
the lightest headphones in its class, weighing just 5.3 ounces. It folds flat, and when folded is slimmer than most
competing models. Included with the HA-NC250 are 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. The headphones use a
single 1.5-volt AAA battery for powering the noise cancellation circuitry. Battery life is rated at about 50 hours.
