Abstract

A stereo audio headphone set may include a master headphone unit including a master housing to be independently carried behind an ear of the user, master circuitry including a stereo audio source and a wireless transmitter coupled thereto, and a master audio output device coupled to the master circuitry for playing a first stereo audio channel from the stereo audio source. A slave headphone unit may include a slave housing to be independently carried behind another ear of the user, slave circuitry including a wireless receiver cooperating with the wireless transmitter, and a slave audio output device coupled to the slave circuitry for playing a second stereo audio channel from the stereo audio source. First and second independently settable frequency equalizers may also be included for the first and second stereo audio channels to permit independent selection of frequency equalization to compensate for hearing loss.
