Disclosed is an earphone device which prevents earphone cables of earphones from being twisted or tangled and decreases the volume of the earphones so they may be easily kept and carried. The earphone device according to an embodiment of the present invention comprises: an earphone jack which is connected to an acoustic device; a pair of earphone speakers which output sound; an earphone cable which extends from the earphone jack by a predetermined length, and is branched to a first earphone cable and a second earphone cable at a predetermined position, which are connected to the pair of earphone speakers, respectively, wherein a coupling protrusion and a coupling groove are formed on faces of the first earphone cable and the second earphone cable facing each other, and the first earphone cable and the second earphone cable are coupled to be separable by male and female coupling of the coupling protrusion and the coupling groove. In addition, a coupling protrusion and a coupling groove are formed on both sides of the earphone cable, and when the earphone cable is wound in a longitudinal direction, the earphone cable is spirally wound by male and female coupling of the coupling protrusion and the coupling groove, thereby being integrally coupled. |
