Did you listen to the youtube video I posted with bog-standard stereo headphones? From what you wrote, I don't think so. You can even use $10 earbuds!
I understood exactly what you wrote.
You were nitpicky to the max and you totally ignored that "surround headphones" may be exactly what you described. You would personally just call them differently. I would even assume that you are trolling now.
My 10$ earbuds aren't able to get me surround sound anywhere BUT FOR THIS ONE SINGLE youtube video, that features audio, which is already encoded that way somewhat (although in lousy youtube quality). All my DVDs aren't encoded that way. All my BluRays aren't encoded that way. My PS3 also doesn't encode audio that way. And the Wii U won't encode the audio that way either. My 10$ earbuds won't be enough to get me surround sound for those.
I did exactly that. And many people who care about audio do. Well, it doesn't literally say "surround sound processing" on the box.
So someone buying so called "surround headphones", which may contain exactly the same as you bought separately, but combined within one package, doesn't care about audio? Elitist nonsense.
And you would call that package "stereo headphones and a virtual surround sound box" because that's technically correct, although they are not sold using that term. And most people also don't call them that way.
So to clarify: You think: "surround headphones == headphones, that contain more than 2 speakers"
Most people ITT think: "surround headphones == a package, that is sold in stores, which contains headphones with 2 or more speakers + a transmitter, that will encode multichannel surround to virtual surround".
