JVC HA-NC120 Noise-canceling Headphones, Standard Packaging
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.
