A hearing aid includes a housing for accommodation of a signal processor for processing an audio signal into a processed audio signal compensating a hearing loss, and a receiver that is connected to an output of the signal processor for converting the processed audio signal into a sound signal, wherein the housing is configured to be positioned in an ear canal of a user without obstructing the ear canal, thereby leaving a passageway between a part of an ear canal wall and a part of the housing so that sound waves can escape from behind the housing through the passageway to surroundings of the user, the housing having an output port for emission of sound towards an eardrum of the user when inserted in the ear canal, and wherein the housing is coupled to an elongate member, which is configured to be placed in a pinna and outside the ear canal of the user for retention of the housing in the ear canal.
