202 1 Mercedes-Benz S-Class Berlin Audio Burmester's high-end 4D surround sound system includes 3 1 speakers and 8 harmonic drivers. Harmonic drivers will enhance the penetration of music, and together with the speakers in the headrest, bring the best sound experience to passengers and drivers. The main instrument supports naked-eye 3D, and the liquid crystal is not an organic light-emitting diode screen. The display effect of the screen is very delicate, supporting a variety of theme modes and having a strong sense of science and technology.
