The utility model discloses an earplug earphone, which comprises an earplug for producing sound and an elastic supporter; the earplug comprises a front shell body and a back shell body which are sequentially connected, the elastic supporter is arranged outside the back shell body. When the earplug is plugged into external auditory canal, the elastic supporter arranged at the side wall of the earplug is deformed under the pressure, which makes the earplug smoothly enter into the external auditory canal. After the earplug is placed in place, the elastic force generated by the elastic supporter due to pressure is exerted on the auricle, which makes the earplug be stably located in the external auditory canal and not easy to slide down, meanwhile the elastic supporter can decrease the vibration to the earplug brought by movement.
