The short story is that you stick microphones in your ears, and it tones out a room, then you put on headphones (without taking the microphones out) and it tones out the cans. It then does a fairly complex FFT to make the two mach with an incoming signal. It has a testing mode where you are supposed to guess if you have headphones on or if it's the speakers playing, for the first 15min or so of this test everyone I know has gotten it wrong at least 50% of the time, it's that good.

That sounds fantastic! So it can theoretically bridge the tonal gap between any monitor and headphone? That must sound amazing with the HD800S

Yes, and yes. There are limitations, low frequency isn't perfect (obviously it's not moving the air that big drivers are, so you don't "feel" the bass the same). And you can't EQ a headphone to do "everything" as all headphones have a limitation but the HD800s are pretty close. Smyth also recommends STAX.

Also, if this isn't obvious, it does all of this at a 7.1.2 soundfield, so you can feed it a dolby atmos mix (or DTS:X) and you hear the full surround mix, with location accuracy. There is also a head tracking feature so you can turn your head and the "room" stays where it is.

Thanks for all the information! I’m going to look into this further. The spatial aspects are very intriguing to me.

It's very cool. It works best if you have access to a great sounding room to model.
