The invention relates to a binaural hearing aid device, comprising a first hearing aid and a second hearing aid, respectively. Each hearing aid comprises a microphone unit, a receiver unit, an audio processor and a speaker unit. The microphone unit is configured to receive an acoustic front tone, indicative of a front part of a surround sound, and to convert the acoustic front tone into an electric front signal. The receiver unit is configured to receive a wireless rear communication signal, indicative of a rear part of the surround sound, and to convert the rear communication signal into an electric rear signal. The audio processor is configured to receive the electric front signal and the electric rear signal and to determine a processed electric rear signal with respect to the electric front signal, by adjusting a time delay between the electric rear signal and the electric front signal and by adjusting a sound level of the electric rear signal according to a sound level of the electric front signal, wherein the audio processor of the first hearing aid is configured to adjust the time delay and the sound level of the electric rear signal differently than the audio processor of t…
