Abstract
An earphone () comprising housing (), a speaker (), a speaker protrusion () extending along a protrusion axis (Z) and comprising an inner protrusion surface () and an outer protrusion surface (), a resilient eargel () comprising an inner eargel surface () and an outer eargel surface (). The eargel () is detachably attached to the speaker protrusion (), such that the outer protrusion surface () abuts an abutment part () of the inner eargel surface () in an abutment zone () extending along the protrusion axis (Z). The eargel () is adapted to be inserted into the outer ear of a user, such that it abuts the ear canal of a user, whereby a cavity () is provided between at least the speaker (), the inner protrusion surface (), the inner eargel surface () and the ear canal. The earphone () is provided with a vent channel () coupling the cavity () and the ambient, wherein the vent channel () comprises a groove () in the outer protrusion surface () or the inner eargel surface (). The vent channel () is provided between the groove () in the outer protrusion surface () and the inner eargel surface () or between the groove () in the inner eargel surface () and the outer protrusion surface (). The groove () comprises a first groove part (), that extends in a plane orthogonal to the protrusion axis (Z).
