PURPOSE: An earphone having sound insulation device is provided to offer stably offering an environment for playing music by offering music with a little nosiness to an eardrum even in a noise environment.;CONSTITUTION: A regenerative signal of an earphone is applied to hearing via a contour(9) of an external auditory canal(10), the external auditory canal, and a sound insulation element(7). Environment noise(12) is applied to the hearing via the sound insulation element. A play sound(4) in the earphone, an environment noise entering through the earphone, and a fricative noise are dampened through the noise shielding effect of the sound insulation element. A part of the external auditory canal is blocked with the sound insulation element.
