Article: Redscape 3D Audio for Headphones Review

I tried the demos with a pair of Shure SRH840 phones but only got hard pan left or right sound.  No sensation of front or surround directions.  I toggled the demo off and on and could easily hear the difference from in head to out but it was just outside the left ear or right ear without going toward the front or back as expected.  Did I miss something?
