It folds flat, and when folded is slimmer than most competing models. Included with the HA-NC250 are a slim carrying case, a four-foot detachable cord, airline dual plug adapter, and ¼-inch plug adapter for use with many home audio and video components. The headphones use a single 1.5-volt AAA battery for powering the noise cancellation circuitry. Battery life is rated at about 50 hours.
