Most closed-back headphones have a treble peak around 9k-10kHz.
Is that really "severe treble roll-off"? Treble is all there to the human ear, with some excess in a particular area.
About the treble spike around 9 kHZ, many, but not all, of their headphones, whether open or closed, show that in their curves. Strange, as I don't recall noticing that on other sites like headroom.
Yes, IMO, that FR curve for the 598 Cs, shows severe treble roll-off. If you exclude the 9 kHz spike, which could be testing or equipment induced, most of the treble is way below the target and even more so relative to the mids. The only exception really being as you approach 20 kHZ, it creeps back up to target, but most adults can't hear beyond about 17 kHZ anyway.
It just reaffirms, except for the boosted mids, the 598 Cs really is a dark sounding headphone. It lacks clarity and sparkle in the treble. This based on actually having owned it for a while.
