Abstract: An earphone system, apparatus, and method enables a user to simultaneously receive auditory stimuli from an earphone-based source and at least one secondary source thereby enhancing a user's personal safety while listening to earphone-based auditory stimuli. At least one primary earphone device having a loudspeaker is positioned adjacent the user's ear so as to allow aural perception of other, non-earphone-based auditory information or stimuli. In a preferred embodiment, an earphone device is both removably fastened and adjustable relative to underlying support structure so as to more properly direct earphone-based auditory stimuli toward the user's ear.
