AKG went into orbit with bin-aural sound processing on board of the space station MIR. Wow I would like to hear those space hps.
I named those hps K240 SDF. (Space Diffusion Fields).
I've ask AKG for more info, looks like the K-240DF cup. The metal/aluminium material looks interesting, I hope is more light compare to the original 240DF hps.
Maybe they will even get into production (my personal dream), I love the look of the metal cups.
