1. A binaural hearing device with improved performance through an adaptive delay, comprising:

  • a first hearing device acquiring a first sound signal, and transmitting a digital signal corresponding to the first sound signal; and

    a second hearing device receiving the digital signal wirelessly transmitted from the first hearing device, whereinthe second hearing device comprises;

    a received signal strength indication measuring unit configured to measure a strength of the received digital signal wirelessly transmitted from the first hearing device, andan adaptive delay circuit configured to adaptively synchronize the received digital signal wirelessly transmitted from the first hearing device with a second sound signal acquired by the second hearing device, the adaptive synchronization being performed by equalizing a phase of the received digital signal wirelessly transmitted from the first hearing device to a phase of the second sound signal acquired by the second hearing device,the adaptive delay circuit further configured to determine a time delay generated per wireless data packet of the received digital signal wirelessly transmitted from the first hearing device based on the measured strength of the received digital signal wirelessly transmitted from the first hearing device by the RSSI measuring unit and to adaptively synchronize the received digital signal wirelessly transmitted from the first hearing device with the second sound signal acquired by the second hearing device based on the determined time delay.
