If you are fine with elevated upper mids 2-4(5)kHz you should be ok with these.6kHz is usually problematic for me. 8kHz is fine.
I find their treble very clean and smooth with hardly any audible peaks or valleys when doing a frequency sweep.
They have good shimmer and energy but for me they are never harsh.
