I have FH1, I bought it in my "pre ChiFi"

period largely based on the looks - "an eye in a ear"
FH1 has an emphasized (if not bloated) bass. Then Knowles BA of FH1 does quite respectful job in smoothness and reaching reasonable highs.
The "sibilance talk" likely came from bass- oriented people moving from from bass-heavy DDs and who did not experience BAs before and started to feel the treble
For me the crossover in FH1 became its weakest point, in some string quartets it became very obvious.
Also, in my limited judgement, ZSN and ZSN pro are very much in the same league as FH1, and I personally prefer the signature, look and feel of CCA CA4 to DH1 (my preferred simple hybrid).
With EA3, Fiio is definitely moving in the right direction: more realistic price, 2-pin instead of MMCX (I personally will not buy any MMCX after experiencing how 2 pin is superior in every way. I strongly feel there is no excuse to use MMCX these days).
