L'écouteur (1) comprend une section de logement de haut-parleur (2) incorporant le corps de haut-parleur (3) et ayant une ouverture (21) pour rayonner une onde sonore à partir du corps de haut-parleur (3), un conduit acoustique tubulaire (4), et un dispositif d'insertion élastique dans la conque de l'oreille (6) entourant le conduit acoustique (4) et la section de logement de haut-parleur (2) partiellement ou entièrement, le dispositif d'insertion dans la conque (6) pouvant être plié près de la jonction (61) avec le conduit acoustique (4).
