The JVC Inner-Ear Noise Cancelling Headphone cancels up to an amazing 80% of background noise, and also features a unique contoured 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 impact. They also feature a monitor function that allows users to mute the sound for conversation or listening to announcements. Provided accessories include three different sizes of ear pieces, dual-plug adaptor, soft carrying case, and one AAA battery which runs the unit for approximately 70 hours.
