Claim:
An earphone device comprising a main body to be inserted in the outer ear of a user, a conchal wall stabilizer extending from the main body and adapted to engage the conchal wall of the ear, the conchal wall stabilizer being able to assume different positions in relation to the main body, characterised in that the conchal wall stabilizer is a bi-stable mechanism, which is movable from a first stable position via a dead point to a second stable position, wherein a bias element biases the conchal wall stabilizer towards the first stable position, when the conchal wall stabilizer is positioned on a first side of the dead point, and towards the second stable position, when the conchal wall stabilizer is positioned on a second side of the dead point and wherein the bias element comprises a spring with a first stable geometry corresponding to the first stable position and a second stable geometry corresponding to the second stable position.
