I've not been able to try the HD800, but I did audition the HD700. The thing I wonder about is the 'removal from the music' that I felt with the HD700. Is this true of the HD800 as well? If it is, does the HD800S rectify this sort of 'clinical' sound?
I do not understand what you mean either, but HD800 and HD700 are earth and sky differece. Do not even try to compare. They have different sounds, signatures, HD700 is neither hd650 nor hd800, it is a thing of it's own, which will not be liked by people who like hd800 nor by people who like hd650. It is like HD700 is for people who dislike both hd650 and hd800, like for that rest of people.
Hd700 is very comfortable, but that is the only similarity to hd800. I was in shock when I heared them, like I was with NAD viso, and with oppo headphones, They are really not my cup of tea. I can understand people liking them, and they working better with other genera of music, but for me, they simply did not work.
On another order of thoughts, HD800 is not clinical in comparation, but the original hd800 is bright.
