A hearing aid, comprising: an outer ear section comprising a microphone for converting sound into an audio signal, and a signal processor for processing the audio signal into a compensated audio signal; a receiver that is connected to an output of the signal processor for converting the processed compensated audio signal into an acoustic signal; an open and flexible earpiece that is adapted for fitting in an ear canal of a wearer, the flexible earpiece having a vent, a depth of the vent being shorter than a length of the earpiece measured along a longitudinal axis of the earpiece, the earpiece having an output port for emission of the acoustic signal towards an eardrum of the wearer when the earpiece is inserted in the ear canal; and a sound tube that is substantially rigid in its longitudinal direction and flexible perpendicular thereto, and interconnects the outer ear section and the earpiece; wherein the outer ear section does not obstruct the ear canal so that the earpiece can provide a venting effect.
