Are you settling for non-3D sound to go with all of your 3D movies? You should be ashamed of yourself. Thankfully, Sony's looking out for you. The company's new MDR-DS7500 headphones promise 3D surround sound, thanks in part to the inclusion of Dolby Pro Logic IIz technology. The headphones have a number of different sound settings, serving different audio needs, including Cinema Mode, Game Mode, and Voice Mode. Also, that extra padding assures that they'll play nicely with your 3D glasses. The headphones will be hitting Japan on October 10th, running ¥49,350 ($643) for the full package and ¥24,675 ($321) for additional headphones. Extra dimensions don't come cheap, after all.
