Right on. This is basically the backstage pass that top reviewers get (even though we have to pay for it, but still). Some sort of secret change to the matte black edition compared to matte black on the LP's, three cables, one of which is this "SharePlay" feature to share with other people but nobody really knows what that means (maybe split? who knows), free set of custom shields (which are $45 a set otherwise, and they're barely making a profit off of the process to begin with), and Val signing something along the way. If it's the headphones and he uses a sharpie, in retrospect perhaps matte black was not the best option xD
But in terms of sound, yes, there shouldn't be any difference in sound, even moreso than the MPU's, as these ones are the ones tested by Val and his tea
