Introduction:
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.
