The invention specifies a hearing device, which has at least one contact means which can be flush with the hearing device housing. The contact means contacts an external unit, for instance a battery charging unit, when in an extended or folded-out position. The unit has a corresponding opening for receiving the contact means. As a result, a reliable connection can be established between the hearing device and the charging device when charging a rechargeable battery of the hearing device for instance. The contact means can comprise first and second contact elements, and third contact elements which correspond to the external unit.
