Pros: Very clear and smooth sound; deepest, fullest and most solid bass ever heard in the iem world, soundstage, luxury looking..
Cons: Plastic fake treble, none-detail sound,super overwhelm bass issue, color sound..
Well, i am a bass-addict and though the bass on this JVC's flagship iem is really outstanding, i really can not love it unless i am considering this bass separately. Yeah, it will be the most iem's subwoofer-likeness bass if it is standing alone. But in this case of the FX700s, the bass affects too much at the mids once you listen to a (semi)heavy bass song. For example: jpop, kpop, hiphop, dance and even R&B =.=
Besides, the general sound of the FX700 is too thick, too color (not dark though) and seriously lack of the detail in the mids, esp in the treble and having a plastic treble like that is existing on almost models of the Denon's sound signature.
