Can't compare, never hear the SF Pro. But I don't get any harshness nor fatiguing at higher volumes any more. But there is something about the reverb in the bass I really like with these that is missing on other IEMs I've owned. Might be the dynamic drivers, not sure. I don't get any harshenss at all, and my sizzle is really just a term used to say I like them, not as a way to describe their sound ... after proper burn-in, that is.
