Hippo VB and Klipsch S4 are sibilant. I am on the fence of including head direct R0 and Panasonic HJE900, some do feel they can be "slightly" sibilant.
RE-ZEROs are smoother in the mids & highs than the RE0s which are a little aggressive.
With some artists like "Sara Bareilles" i found the RE0s to be a little sibilant.
I haven't heard any of the other above IEMs but have kept away from them because of the reviews relating to some sibilance or the highs being aggressive.
The Soundmagic PL50 are very smooth too, but the dynamic drivers of the RE-ZEROs were a level up in SQ in comparison the the BA PL50s.
Also the klipsch X5s are very smooth BAs which would be a good buy if you got them under $100.
Of the non sibilant smooth iems ive had i would go this way RE-ZEROs > Klipsch X5 > PL50s
