Well, I did't check on Crin's site, his BK5128 measurements are surely most reliable, especially in the treble area:

Anyway that was just to get an idea of the FR differences between the 2 iems that surely impact spatial and imaging perception.
They are pretty close, to be fair; one can't argue with that. Maybe the differences I hear come mostly from how deeper the FH9s sit in my ears, because I get much more bass from the FH9s with default tuning; which seems to contradict the graphs.
You can get an idea of how much deeper one sits compared to the other with this picture:
Also, I don't think that the semi-open back can be measured with FR.
