A hearing aid device configured to be inserted into the ear canal of a hearing aid user. The hearing aid includes a receiver, a hearing instrument body, and a connection member extending between the hearing instrument body and the receiver. The connection member is a permanent part of the hearing aid device and the connection member has a stiffness that allows the receiver to be inserted into the ear canal by moving the hearing instrument body towards the eardrum. The connection member achieves a first stiffness sufficiently large to insert the hearing aid device into the ear canal and achieves a second significantly reduced stiffness which makes the hearing aid device comfortable to wear for the user.
