I've owned the silver HD800 for some years and currently own the black HD800S.As I was originally looking for a pair of headphones that surpasses my current HD 599, I wanted to try and find something that was even more accurate and clear, such as maybe the HD 800. However, it turns out that these are discontinued, and that the only option is to get them used. On the other hand, there's still the HD 800 S. This is what I found out.
The HD 800 S has slightly distorted bass and less treble than the HD 800, and is a more "colored" headphone with less soundstage. That somewhat worries me, because I've heard this description when comparing the HD 650 to the HD 600, despite me not knowing how much of a difference it truly is.
I guess I worry that, if I get a pair of headphones that's "warm-leaning", then it might sound like the bass is too distorted, and the mids to highs would sound recessed, especially for a pair that costs as much as the HD 800 S. Then again, I have no idea how much. Some say they sound exactly the same, others say they sound quite different.
(Also want to say that I have no idea how HD 800 S "distorted" bass compares to something like... say, Beats bass.)
