The HANCX77 is JVC's first in-ear style noise canceling headphones reflecting JVC's commitment to style and technology. It cancels up to an amazing 80% (more than 14dB at 120Hz) of background noise, and also features a unique contoured canal design earpiece that's slightly angled, allowing a natural and secure fit that provides 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 impacat. The HANCX77 also features a monitor function that allows users to mute the sound for conversation or listening to announcements. Provided accessories include three different sizes ear pieces, dual plug adaptor, soft carrying case, and one AAA battery which runs the unit for approximately 70 hours. Less
