A earbud set comprising: a body part; a leg part foldably connected to the body part; and an elastic body connected to the body part and to the leg part, wherein, the earbud set is supported in the ear, and characterized in that: - the body part is a hollow polyhedron with rounded corners and is divided into a first portion and a second portion by a partition wall fixed to a first surface and spaced apart from an opposite second surface of said body part, - a first through hole is provided on a first or on a second surface of the first portion; - a head of the leg part is coupled to the second portion, by means of a coupling pin (p) coupled to respective holes formed at both sides of the second portion, - a second through hole is formed in a first surface of the second portion so that the head of the leg part is inserted in the second portion of the body part and the leg part can rotate with respect to the body part, and - a guiding part, which projects obliquely toward the second portion from the second surface of the body part, is provided at a position which is spaced apart from the partition wall toward the second portion; - the leg part comprises a through cavity having a L-shaped path and being connected to a guiding pipe formed by the partition wall and the guiding part; - the leg part comprises a foot which is suitable to be inserted into an earhole; and wherein, when the earbud set is worn in the ear, the foot presses against an inside part of the earhole, an outer surface of the first portion of the body part presses against the inner conch and an outer surface of the second portion of the body part presses against the tragus, due to a restoring force of the elastic body. a body part; a leg part foldably connected to the body part; and an elastic body connected to the body part and to the leg part, wherein, the earbud set is supported in the ear, and characterized in that: - the body part is a hollow polyhedron with rounded corners and is divided into a first portion and a second portion by a partition wall fixed to a first surface and spaced apart from an opposite second surface of said body part, - a first through hole is provided on a first or on a second surface of the first portion; - a head of the leg part is coupled to the second portion, by means of a coupling pin (p) coupled to respective holes formed at both sides of the second portion, - a second through hole is formed in a first surface of the second portion so that the head of the leg part is inserted in the second portion of the body part and the leg part can rotate with respect to the body part, and - a guiding part, which projects obliquely toward the second portion from the second surface of the body part, is provided at a position which is spaced apart from the partition wall toward the second portion; - the leg part comprises a through cavity having a L-shaped path and being connected to a guiding pipe formed by the partition wall and the guiding part; - the leg part comprises a foot which is suitable to be inserted into an earhole; and - the body part is a hollow polyhedron with rounded corners and is divided into a first portion and a second portion by a partition wall fixed to a first surface and spaced apart from an opposite second surface of said body part, - a first through hole is provided on a first or on a second surface of the first portion; - a head of the leg part is coupled to the second portion, by means of a coupling pin (p) coupled to respective holes formed at both sides of the second portion, - a second through hole is formed in a first surface of the second portion so that the head of the leg part is inserted in the second portion of the body part and the leg part can rotate with respect to the body part, and - a guiding part, which projects obliquely toward the second portion from the second surface of the body part, is provided at a position which is spaced apart from the partition wall toward the second portion; - the leg part comprises a through cavity having a L-shaped path and being connected to a guiding pipe formed by the partition wall and the guiding part; - the leg part comprises a foot which is suitable to be inserted into an earhole; and wherein, when the earbud set is worn in the ear, the foot presses against an inside part of the earhole, an outer surface of the first portion of the body part presses against the inner conch and an outer surface of the second portion of the body part presses against the tragus, due to a restoring force of the elastic body.
