Claim:
1. A circumaural audio headphone comprising: an earcup configured to overlie a pinna of a first ear of a user; a first transducer supported in the earcup to convert a first audio signal to first sound waves that are provided directly to the pinna of the first ear, wherein the first transducer is connected to receive the first audio signal from a left stereo channel of an external stereo audio playback device; a second transducer supported in the earcup to convert a second audio signal to second sound waves that are provided directly to the pinna of the first ear, wherein the second transducer is connected to receive the second audio signal from a right stereo channel of the external stereo audio playback device; wherein the first transducer and second transducer are spatially displaced from one another in the earcup so that the first sound waves from the first transducer and the second sound waves from the second transducer are directly provided to the pinna of the ear via an unobstructed path and without occluding the ear canal of the first ear of the user; and wherein the earcup comprises a removable backpiece to allow the user to configure the earcup as an open earcup to allow external sound to enter the earcup and pass through an opening to allow the user to monitor the external sound, and as a closed earcup configured to block external sound from entering into the earcup, wherein the first and second transducers are located on opposite sides of the opening.
