First of all, what you say is wrongHm... it is really not true and not a fair comparison. First of all lets play in the same price range: US700. Sony has only XBA-Z5 hybrids in same pricerange. I own both XBA-Z5 and FH9. Tested on ZX507, M17, Kann Alpha, SP2000... FH9 always win more open and bright sound with superrior bass XBA-Z5 fully v-shaped and has tonns of losses espesially in mid. But might be it sould be special player Same like with EI900 I plug them everyware and did not belive that this IEMs cost so mutch till I plug them into SP2000 where they been fully opened WOW it was really amazing!!! Second, you used to listen "Japanise" sound FIIO more "American" profile of sound I have a fiend who creasy from AKM Velvet sound He cannot listen anything else exept "Japanise" V - shaped profile So compearising two different brands wold be wery complicated.
The FH9 doesn't have more midrange, nor is the XBA-Z5 V-Shaped. They are tuned almost identical. The FH9 is actually more V-Shaped than the XBA-Z5.
Also I don't understand why the technology is important. If the IER-M7 is better, it doesn't matter what technology it uses. If it's in the same price range, it should be comparable.
he FH9 sounds more bright, but does have less details. So it's treble is louder, but not better.
That is a difference and important, because that is the reason, why the layering is worse on the FH9
The FH9 sounds less authentic and disjointed with worse layering. You say the FH9 sounds brighter like it's an advantage. But this is actually the reason why it's worse because this is (one of the factors), that makes music sound less authentic and limits the use cases.
With the XBA-Z5, you can listen to every genre, no matter what. With the FH9, you can't. This is _not_ an advantage.
