A hearing device, e.g. a hearing aid, adapted for being located at or in an ear of a user comprises first and second electrically connectable hearing device parts having separate first and second housings, at least the second hearing device part being available in a multitude of variants, each variant providing different functionality to the hearing device, a connecting element configured to electrically connect the first hearing device part and the second hearing device part. The connecting element comprises an electric cable comprising a multitude of electric conductors, and a first electric connector comprising a multitude of first electric termination elements. The first or second hearing device part comprises a second electric connector comprising a multitude of second electric termination elements configured to electrically connect conductors of the cable with electric components of the first and second hearing device parts when the first and second electric connectors are joined. The second hearing device part comprises a loudspeaker, and/or a number of sensors for sensing a current property of the environment of the hearing device and/or a current state of the user wearing the hearing device. Each of said number of sensors provides an electric sensor signal representative of a property of the environment or a state of the user, wherein said loudspeaker and/or said number of sensors are electrically connected to said first hearing device part via said connecting element. The first hearing device part or a programming device electrically connected to the first hearing device part comprises a configuration extractor electrically connected to said second hearing device part via said connecting element and adapted to identify a current configuration of sensors in said second hearing device part. The invention may e.g. be used in portable hearing devices ('wearables'), comprising a main part and an accessory part that comes in a multitude of variants, e.g. hearing
