That makes sense, given the description of how it works, but the article distinctly mentions getting this effect from gaming headphones so...
Anyway, I went and tried again with just my laptop (based on the person above effusing about it). Again, for me, I'm not hearing anything special, and nothing "3D" about the sounds, other than some left-right shifts. And I guess the music is in front of me, since that's where my laptop is ;)
