I have a set of Logitech G930 wireless headsets, which I rather like except for the fact that they're advertised as "7.1", which couldn't be a more false statement. Sure, the software interface presents itself as 7.1 discreet channels, but you still have only two drivers. They're reasonably good as stereo headphones, but for "surround" mode they use some Dolby surround psychoacoustics nonsense, which as far as I can tell, basically ups some reverb in the software preamp and makes everything sound like you're in a steel drum. What an advancement. Not.
In comparison to a much older Turtle Beach headset which actually has 5.1 drivers (with the requisite squid like mess of input leads) Logitech with Dolby space magic falls flat on its face. That headset actually gives you positional audio, and doesn't make you feel like room mate to Oscar the Grouch. Still, I put the Logitech on for more casual use, because they don't have a cord to get caught in the wheels of my chair.
I expect this "new" binaural 3D sound to be equally uninspiring. Good stereo will always be better than bad surround, and judging by everyone listening to their white earbuds, they don't care enough to get the most out of stereo.
