the first working principle and the second working principle are same, or

the first working principle and the second working principle are different.

3. The hearing aid system according to claim 1 , wherein the first working principle and the second working principle are partially different.

4. The hearing aid system according to claim 1 , wherein the first auditory unit and the second auditory unit are worn at different ears of the user.

5. The hearing aid system according to claim 1 , wherein

the first auditory unit is configured to receive a first command from the user and to process the first command; and/or

the second auditory unit is configured to receive a second command from the user and to process the second command; and/or

a remote control, in a communicative link with the first auditory unit and/or second auditory unit, is configured to receive the first command and/or second command from the user and to transmit the first command and/or second command to the first auditory unit and/or second auditory unit respectively; wherein

the processing of the first command and/or second command generates the aligned auditory perception.

6. The hearing aid system according to claim 5 , wherein

the first command comprises the related parameter value and a first instruction set adapted to be executed by a signal processing unit associated with the first auditory unit, the execution of the first instruction set adjusts the first parameter value of the parameter with respect to the second parameter value by the related parameter value; or

the second command comprises the related parameter value and a second instruction set adapted to be executed by a signal processing unit associated with the second auditory unit, the execution of the second instruction set adjusts the second parameter value of the parameter with respect to the first parameter value by the related parameter value; or

the first command comprises a first part of the related parameter value and a first instruction set adapted to be executed by a signal processing unit associated with the first auditory unit and the second command comprising a second part of the related parameter value and a second instruction set adapted to be executed by a signal processing unit associated with the second auditory unit, the execution of the first instruction set adjusts the first parameter value of the parameter by the first part of the related parameter value and the execution of the second instruction set adjusts the second parameter value of the parameter by the second part of the related parameter value such that an effective adjustment produced by the first part of the related parameter value and the second part of the related parameter value equals to the related adjustment produced by the related parameter value between the first parameter value and the second parameter value.

7. The hearing aid system according to claim 1 , wherein the parameter comprises features that characterize performance of the first auditory unit and the second auditory unit, the features being capable of influencing localization ability and/or speech recognition from an audio signal.

8. The hearing aid system according to claim 1 , wherein the related parameter value is established for different scenarios selected from a group consisting of different sound environment, different locations, different events, different audio frequencies, different audio frequency ranges, and a combination thereof.

9. The hearing aid system according to claim 1 , wherein the processing unit associated with the first auditory unit and/or second auditory unit and/or the remote control is adapted to generate a look-up table comprising a mapping between a scenario and a related parameter value for at least one parameter.

10. The hearing aid system according to claim 1 , wherein the first auditory unit comprises a first memory and/or second auditory unit comprises a second memory and/or the remote control comprises a remote memory, the first memory and/or the second memory and/or the remote memory being configured to store the look up table.

11. The hearing aid system according to claim 1 , wherein a processing unit associated with the first auditory unit and/or the second auditory unit and/or the remote control is configured to

detect a scenario for the first auditory unit and the second auditory unit;

access, in response to the detected scenario, the stored related parameter value from the look-up table, and

adjust, utilizing the accessed related parameter value, the first parameter value relative to the second parameter value for a parameter such that the aligned auditory perception is obtained or adjust the parameter value of the auditory unit associated with the parameter where the parameter is only associated with one of the auditory units.

12. A method for operating a hearing aid system, the method comprising:

receiving a related parameter value for a parameter at a first auditory unit and/or a second auditory unit, the first auditory unit utilizing a first working principle, the second auditory unit utilizing a second working principle; and

processing the received related parameter value at the first auditory unit and/or the second auditory unit such that an aligned auditory perception between a first auditory perception produced by the first auditory unit and a second auditory perception produced by the second auditory unit is obtained, wherein

the related parameter value defines a relative adjustment between a first parameter value associated with the first auditory perception and a second parameter value associated with the second auditory perception or an adjustment of the parameter value of the auditory unit associated with the parameter where the parameter is only associated with one of the auditory units, and

the first working principle and the second working principle are selected from a group consisting of electrical stimulation, mechanical stimulation, acoustic stimulation, optical stimulation, and a combination thereof.

13. The method according to claim 12 , wherein the received related parameter is received based on manual input from a user or automatically in dependence on access of the related parameter value from a look up table based on scenario detection.
