An earphone minimizes the design elements for importing sound. It operates without a battery, is lightweight, harmonizes the design and ventilation of the paths for sound transmission, insulation and exhaust, and for augmenting and/or alleviating speaker vibration, and has its outer sound path and transmission path tilted. The earphone comprises a speaker, a body with a cover, a speaker sound path in the body to transmit sound toward the external auditory canal, and a worn portion including a cushion in a holder enclosing the speaker path worn in the external auditory canal. The body includes an outer sound path which imports sound. The worn portion includes a transmission path that receives the sound from the outer sound path and transmits it toward the external auditory canal. The outer sound path and transmission paths are insulated from sound from the speaker and the speaker sound path, respectively.
