An earphone device includes a case main body, a sound conduit, and an ear tip. The sound conduit is formed in a substantially tubular shape and protrudes from the case main body. The sound conduit has a flange disposed at the end on the opposite side from the case main body, and a first restrictor disposed between the flange and the case main body. The ear tip has a ring part formed of a resilient material and configured to be engaged to the sound conduit. The ear tip is configured to be in a first state in which movement in the direction of removal from the sound conduit is restricted by the flange, and is configured to be in a second state in which movement in the direction of removal from the sound conduit is restricted by the first restrictor.
