1. A hearing aid, comprising:

  • a transceiver unit for establishing a wireless communication link using a digital modulation scheme with a packet-based frequency hopping scheme including an advertising channel, wherein the transceiver unit is configured to receive audio data;

    an antenna;

    an antenna tuning circuit physically coupled to the transceiver unit and the antenna for tuning the antenna,wherein the transceiver unit is adapted to estimate strength of signals received in the advertising channel and to transmit a control signal partially based on the estimated strength of signals;

    wherein the antenna tuning circuit is adapted to tune the antenna partially based on the control signal, wherein tuning the antenna includes reducing a frequency range for transmission or increasing transmission strength of signals associated with the advertising channel, andwherein the transceiver unit is adapted to judge whether an interferer is present during the estimation of the received strength of signals in the advertising channel and to use the respective estimation of the received strength of signals only in case that it has been judged that there is no interferer present.
