I can understand that impression, although my listening notes in post #1 state otherwise. I think because the FI-BA-SS have more prominent highs than the e-Q7, they tend to appear somewhat lighter in bass. But I bet if you'd A/B them and concentrated on the bass range you'd find the same.
We hear things differently and equally important, we also listen to different kinds of music. Plus there's the aspect of looking at the sound signature of IEMs as a whole, versus looking specifically at a certain frequency range (bass/mids/highs).
The FX700 have clearly more bass quantity than the SM3, if you just look at bass alone. Yet the JVCs have also very forward highs to counterbalance that bass. In comparison the SM3 have rather laid-back upper mids and highs, and therefore (to my ears) their overall sound signature is warmer and more tipped towards the lower frequencies than the FX700's.
Shows what comes out when one goes by auditory memory - even if it's only been a few weeks since I heard the e-Q7 last, the results are anecdotal. :)
It sure is as you say - it's the whole sound signature that influences how one perceives one specific frequency range in relation - especially since the FADs have really too much, too hot treble for my ears. They're basically the only IEMs yet where I had to EQ the treble down to suit my taste. They should do well for the 50+ demographic, or PCM1704-equipped players... ;)
As for different music tastes - what kind of music do you prefer the FADs with? I haven't found anything yet where they would make my jaw drop. They're certainly nice, but not *that* nice, for my tastes.
