Abstract
A wireless earphone comprising an in-ear portion which is in contact with a human ear when the wireless earphone is worn. The in-ear portion comprises a wearing surface which couples the human ear canal when the wireless earphone is worn. The in-ear portion is provided with a wearing detection sensor, a sound venting hole and a contact group which are all disposed on the wearing surface. The wearing detection sensor, the sound venting hole and the contact group are all disposed on the wearing surface of the in-ear portion coupling the human ear canal, so that the wearing detection sensor can directly contact the skin of the human body when the earphone is worn, and thus the wearing detection sensor is improved.
