Well here are my impressions on the FH3:
Treble is very good in refinement, not peaky for me at all except for like 1 out of the hundreds of songs I went through. Extension is good and there is air (of course my LZ A6 puts it back in its place in terms of air and extension lol).
Mids are very evenly balanced with the treble and the male/female vocal balancing are also very good. Both male and female vocals are detailed and very natural sounding.
Technicalities such as timbre, soundstage, instrument separation and details are very good too.
And the abolute best part…the bass. Oh boy does it put a smile on my face. IT IS NEAR IDENTICAL TO THE URBANFUN ISS014!!! Hell it is actually a tiny bit faster and tighter than the urbanfun!
(The urbanfun is dead in my book becasue of their damn qc problems but even without factoring in that, the FH3 does EVERYTHING better than it and also takes the bass that made the urbanfun famous)
