Abstract: The data of a hearing device system with two hearing devices are to be available in a more comfortable manner. To this end, provision is made for each of the two hearing devices to be equipped with a data acquisition facility, in order to acquire internal signal processing data and/or external data. The two data acquisition facilities and/or the hearing devices are designed to establish a wireless communication link. A synchronized data acquisition is possible in both hearing devices with the aid of this link. This binaural wireless data logging dispenses with the need for comparing the recording times (synchronization). A division of the recording onto two hearing devices enables storage capacity to be saved.
