The application further relates to a method of operating a binaural hearing assistance system. The object of the present application is to provide an improved binaural hearing assistance system. The problem is solved in that each of the first and second hearing assistance devices comprises a) a first wireless interface comprising first antenna and transceiver circuitry adapted for establishing a first communication link to the respective other hearing assistance device based on near-field communication; b) a second wireless interface comprising second antenna and transceiver circuitry adapted for establishing a second communication link to an auxiliary device based on far-field communication; c) a link control unit operatively coupled to the second antenna and transceiver circuitry and configured to repeatedly provide a second link quality measure indicative of a link quality of the second communication link; wherein the first and second hearing assistance devices are configured to exchange said respective second link quality measures between them via said first and/or second communication links. This has the advantage of providing a robust and flexible system. The invention may e.g. be used for binaural hearing assistance systems, e.g. binaural hearing aid systems, where audio quality and power consumption has to be mutually optimized.
