Binaural hearing system having two hearing instruments to be worn in or on the ear of the user, and method of operating such a hearing system

A binaural hearing system, comprising:

• two hearing instruments each to be worn in or on an ear of a user;
• each of said two hearing instruments having a programmable signal processor for modifying an audio signal, an output transducer connected with said signal processor for outputting a modified audio signal, and a transceiver for data exchange with the respectively other hearing instrument;
• firmware having a plurality of software modules installed in the hearing system;
• wherein the software modules are executable in said signal processors of said two hearing instruments;
• wherein the software modules of the firmware are distributed or distributable asymmetrically on the two hearing instruments, so that in operation of the hearing system at least one of the software modules of the firmware is selectively executed in one of said two hearing instruments;
• and
• a distribution unit configured, upon a start or in operation of the hearing system, to dynamically select at least one of the software modules of the firmware on which of said two hearing instruments the at least one software module is to be executed and to cause the selective execution of the at least one software module on the selected hearing instrument, and
• wherein said distribution unit is configured to distribute multiple software modules of the firmware for respective selective execution on said two hearing instruments of the hearing system in such a way that a demand for processing power and/or operating memory space for the software modules respectively executed on said two hearing instruments is equal to one another.
