The earphone includes an electroacoustic transducer for converting an audio signal into sound and a housing for holding the electroacoustic transducer. The housing includes a sound output unit for introducing the sound produced by the electroacoustic transducer into the ear canal of an ear when the housing is placed in the ear. The electroacoustic transducer is oriented so that it emits the sound in a direction which is transverse to the ear canal of the ear.
