HA-NCX77 In-Ear Noise-Canceling Headphones

JVC's first in-ear style noise-canceling headphones HANCX77 reflect JVC's commitment to style and technology. It cancels up to amazing 80% (more than 14dB at 120Hz) of background noise. The unique contoured canal design features an earpiece that's slightly angled, allowing a natural and secure fit for maximum sound isolation. Because of the superb ambient noise seal, precise acoustic coupling to the eardrum can be employed, thereby lowering the volume required to achieve the full sonic impact. The HA-NCX77 also features monitor function that allows users to mute the sound for conversation or listening to announcements. Provided accessories include three sizes ear pieces, dual plug adaptor, soft carrying case, and one AAA battery which runs the unit for approximately 70 hours.
