I was told by Stephen that they use the 800 because it is very comfortable and easy to forget that you are wearing.
He said that the system calibrates itself to the headphone used and EQ's for a flat response.
He went on to say that if you were intending using your headphones exclusively with the Realiser there would be little point buying the 800S rather than the 800 as the system would make them sound the same.
So if there was an opportunity to buy a discounted 800 he suggested grabbing it.
From that I assume that you will get similar results whatever headphone of good quality you use.
