The present invention provides an earphone that reduces a contact sound generated when, for example, one moves while wearing the earphone or generated upon contact of a wiring or a substrate (component) with clothing or the human body and a frictional sound when the clothing or the skin of the human body rubs against the wiring or the substrate (component), and suppresses an unpleasant sound that would otherwise be heard from these sounds through the wiring. The earphone is provided with a pair of left and right speakers and a circuit to drive the speakers, and further provided with at least one substrate having a circuit including a communication circuit and/or a cell and a wiring for connecting the left and right speakers together or a wiring for connecting the left and right speakers separately to the substrate, the wiring having elasticity.
