Abstract
A headphone and method for allowing manually controlled reception of ambient sound by a user. More particularly, the invention relates to a headphone for listening to an audio signal while allowing varying amounts of ambient sound to the user. In one aspect, the headphone comprises a manually-controllable physical characteristic that controls the amount of ambient sound accessible to the user. The physical characteristic can be sound ports that can be opened or closed. In another aspect, the headphone can comprise a microphone receptive of ambient sound, wherein the user can control the proportion of sound that comes from the ambient sound or the audio signal. The microphone can be part of a noise cancellation system.
