There is provided a fitting device configured to be communicatively connected to first stimulation device (10) comprising an implantable neural stimulation device (12) including a plurality of stimulation channels for neural stimulation of a patients ipsilateral ear at various stimulation sites according to a neural stimulation signal and a second stimulation device (21) selected from the group consisting of a device for vibrational stimulation of the patients ipsilateral ear and a device for vibrational stimulation of the patients contralateral ear according to an acoustic stimulation signal for adjusting the first stimulation device and the second stimulation device. The fitting device (13) comprises a graphical user interface (31) and is configured to allow a user to select between a HA-type fitting mode and a Cl-type fitting mode, wherein each mode is suitable for fitting both the first stimulation device and the second stimulation device. The fitting device also comprises a transformation layer for transforming an input from the graphical user interface into fitting parameter values to be written to the stimulation devices and for providing for an input to the graphical user interface according to fitting parameter values read from the stimulation devices.Linvention concerne un dispositif dajustement configuré pour être relié de manière à communiquer avec un premier dispositif de stimulation (10), comprenant un dispositif de stimulation neuronale implantable (12) comportant une pluralité de canaux de stimulation destinés à la stimulation neuronale de loreille ipsilatérale dun patient au niveau de divers sites de stimulation en fonction dun signal de stimulation neuronale, et un second dispositif de stimulation (21) choisi dans le groupe constitué par un dispositif destiné à la stimulation vibratoire de loreille ipsilatérale du patient et un dispositif destiné à la stimulation vibratoire de loreille controlatérale du patient en fonction dun signal de stimulation
