MDR-DS7500 new society promised 3D surround sound headphones, thanks in part to the inclusion of Dolby Pro Logic IIz. The earphones have a number of different sound settings, audio serving different needs, including the Cinema mode, game mode, and the voice mode. Also, that extra padding ensures that they will play nicely with your 3D glasses. The helmet will hit Japan on October 10, running 49.350 yen ($ 643) for the whole package and 24.675 yen ($ 321) for additional headphones. Extra dimensions are not cheap, after all.
