The earplug is characterized in that a pin is arranged in the shell and the pin passes through the shell; the pin is connected to two earplug wires and connected to the earplugs arranged on end portions of the earplug wires; the earplug wires pass through earplug outlets arranged on two sides of the shell respectively; a take-up device is arranged in the shell and the earplug wires wind the take-up device. By using the earplug, installation, wire drawing and wire take-up are convenient. Compared to a traditional take-up device, by using the take-up device of the utility model, good cooperation with a mobile phone can be realized and an effect of protecting the earplug can be achieved during separate use.
