Actually that does make sense - though what it does to the resolution of
localisation or whether pinna filtering will work with the drivers so close
remains to be seen - exciting if they've got it to work . Im sure I read
something about the US military trying this out somewhere.
There is another
crushingly simple and obvious way of calibrating HRTFs though which I'm not
sure anyones thought of yet - whenever I say that it always turns out
somebody has years ago but anyway....
Please tell us about this (secret) smashing but simple way... Can't
wait to learn about this one! :-D
Best,

when you have four speakers to each ear, you can think of a decode to a
cube. The only big difference between a cube mounted at a distance and this
would be the importance of the head shadow. If you can cancel head movement
(which headtracking does) it is very similar to listening to a cube of
speakers in a room. there are some details of course. You do not need
individual HRTFs. I am not sure what different head sizes will do. If the
foam support compresses (and the distance to the drivers is fixed) it may
not matter.

Not sure they would. As they are over the ear headphones, one doesn’t need
pinna HRTF as ones own would function.
They probably made HRTF files for each driver position. That way your own
pinna effects would function.

Theyd still have to somehow measure the pinna dimensions though - which
is
the most important part for vertical localisation - without that it wont
work with just shoulder reflections and headwidth.......

Based on what I had gathered from some video some time ago, my guess is
that they use some kind of HRTF model that takes into account the user's
head width, combined with the 4-driver system. I guess the first would
act
mostly on low frequencies and the latter on higher frequencies that
would
be harder to model. However the last part is only a guess which I'm not
sure about.
