Well, the way I see it:
Very obvious flaws will be pointed out by anyone, no matter how knowledgeable they are.
I am looking for things like:
- Harshness in the treble
- Poor fit
- Build Quality issues
- Any other flaw that hinders the user experience
So I will not be buying the ZS6 because of the "harshness in the treble".
You may be right, but not forget that a lot of this things con be subjective. Casual's review are not that trustworthy.
Treble's harshness, as we said before, can be perceived differently. Same thing for fit, and it also can have impact on sound.
As for me, i know that i have place a huge bet on ZS6, for my treble's liking, but this time i'm also in the right mood for mod and EQ them, if something go wrong. Like we can place felt, toilet paper or other materials between pads and driver on bigger headphones, searching for our personal balance of treble's presence, we need to understand that it's a problem that need to be approached with personalization, if we can also want some audible upgrade and more details overall. I said it before, sibilance exist on nature and recording. A sibilant headphone is not a bad headphone, per se.
All i was thinking, when i have place the order, is that i want that potential on bass and mids, that soundstage and instrument separation, with more quality construction and exchangeable cable ( i have ordered the copper KZ's cable ), because i'm also too damn tired of listen stronger microphonics on a lot of cheap IEM.
35-40$ are too much for that ? maybe, and maybe there is some better alternative to this model, that other users can recommend, but it also can be said that some guys buy and mod a LOT more expensive stuff, searching for their personal vision of an audio heaven.
