Abstract: An earphone capable of making it easy to remove foreign substances that have accumulated on a nozzle portion and easy to control sound characteristics thereof is provided. The earphone includes a driver, a housing defining an electrical component mount on which the driver is mounted, a nozzle portion provided at one end of the housing and defining therein a nozzle hole communicating with the electrical component mount, a nozzle cap detachably coupled to an outer circumferential surface of the nozzle portion, and a nozzle mesh provided at the nozzle cap so as to cover the nozzle hole, wherein the nozzle cap serves to decrease output in a second peak region in a graph of output over frequency for the earphone and to increase a fourth peak region or expand a bandwidth of the fourth peak region in the graph.
