## Abstract

A binaural hearing system (1) comprising two hearing devices (2, 2′) for arrangement in a user's left and right ear, respectively, each of said devices (2, 2′) comprising a processor (3, 3′), a secondary battery (4, 4′), a microphone (5, 5′), a receiver (6, 6′), a wireless interface (7, 7′) for enabling at least a wireless connection (13) between the two hearing devices (2, 2′), a socket (9, 9′), a link cable (10) for interconnecting the two hearing devices (2, 2′) by connecting the link cable (10) to each of said sockets (9, 9′), wherein the processor (3, 3′) is configured such that the wireless connection (13) is disabled, when the two hearing devices (2, 2′) are interconnected by the link cable (10), the link cable thereby enabling a wired connection between the two hearing devices (2, 2′).

## Claims

### Claim at position 1

1-15. (canceled)

### Claim 16

A binaural hearing system comprising:
a hearing device configured for a left ear;
a hearing device configured for a right ear;
each of hearing device comprising:
a processor,
a battery electronically coupled the processor,
a microphone electronically coupled to the processor,
a receiver electronically coupled to the processor,
a wireless interface for enabling a wireless connection between the left and right hearing devices,
a socket electronically coupled to the processor,
a link cable configured to electronically interconnect the hearing devices via the sockets,
wherein the processor is configured to disable the wireless connection when the two hearing devices are interconnected by the link cable.

### Claim 17 (depends on 16)

The binaural hearing system of claim 16, wherein the link cable comprises an auxiliary transmitter.

### Claim 18 (depends on 16)

The binaural hearing system of claim 16, wherein the link cable comprises an integrated power supply unit that is electronically coupled to both hearing devices by means of the link cable.

### Claim 19 (depends on 18)

The binaural hearing system of claim 18, wherein the link cable comprises a power connector that operationally connected to both hearing devices by means of the link cable, wherein the power connector is adapted to be connected to a detachable power supply unit.

### Claim 20 (depends on 19)

The binaural hearing system of claim 19, wherein the link cable comprises a link connector at each of its free ends, wherein each link connector comprises manually releasable fixation elements for securing the link connectors to the respective hearing device.

### Claim 21 (depends on 20)

The binaural hearing system of claim 20, wherein each of the two hearing devices further comprises a controller configured to detect when the link cable is interconnecting the two hearing devices.

### Claim 22 (depends on 21)

The binaural hearing system of claim 21, wherein the controller is configured to enable a power sharing between the secondary batteries of the two hearing devices.

### Claim 23

A hearing device comprising:
a processor,
a secondary battery,
a microphone coupled to the processor,
a receiver coupled to the processor,
a wireless interface for enabling a wireless connection to another hearing device,
a socket electronically coupled to the processor,
wherein the processor is configured to disable the wireless connection when the two hearing devices are interconnected by the link cable.

### Claim 24 (depends on 23)

The hearing device of claim 23, wherein the hearing device further comprises a controller configured to detect when the link cable is interconnecting the two hearing devices.

### Claim 25 (depends on 23)

The hearing device of claim 23, wherein the controller is configured to enable a power sharing between the secondary batteries of the two hearing devices when they are interconnected by the link cable.
