I can agree with a lot of what you've written, but I'm pretty sure from what I hear that the NDH 30 is clearly a much higher level than the HD660s. And it's definitely not at all close to the 560. Just compare it in sound directly to one another. And I'm sure you'll hear the difference.Ok but what cable is this ? From what company any link?
Like u said listening 660s after NDH 30 u feel like u are behind a veil , this is how some people that dont like HD6 line describe it so yes u are correct . Its normal for u to think that .
U should compare NDH 30 with lower end HD560s headphone that share a lot more common things. And i am sure u will love more light more reliable and less expensive headphone that NDH 30 is based of. I know because i got the shame feeling like u did . But again is something different .
HD 6 line is all about natural sound smooth sound realistic timbre that others dont have , and about imaging and speed HD660s has not opponent under 1.000 euros that are not Planar.
Again NDH 30 aka more expensive heavier 560s are amazing for people that like this signature its nothing wrong with that , but technically in my opinion are not even close to HD6 line . U can try to eq if u like the HD6 series will follow easy the signature of NDH30 in both ends.
What u said about the selected signature of HD6 line ( vocals and almost perfect mids ) that is suitable for minimum genres.... Sory u are Very wrong and thats a fact most music and hear listening is on midrange band.
And i am not even talking about most people listening music with vocals .
So ok i agree 560s NDH 30 sound more flat and have that clear sense but to some people what u say clear to them is grainy or bright ... For u is something else and HD6 are veiled . But the fact is that even if they sound veil to u the great resolution,speed,imaging, separation, openess vocals mids are there on HD660s even if u dont like this signature.
Where I work, there are a lot of people around who work with sound and they each have almost ten or more headphones of different price ranges, from 100 to 3000. I can literally walk out the door and pick up different headphones from them and compare it for hours. I've done this several times and I'm already tired. It makes no sense. My colleagues who work professionally with sound have already chosen the NDH 30, even sacrificing expensive planars. That's because the NDH 30 is pure and true natural sound with no signature. Such a sound does not get bored in work, not in listening to music. In my example, after two months of listening to them, I want to listen even more. This has not happened with other headphones.
HD660 s bored me in music in just a few days.
Just like planar models. I just hear that the sound is not right and I get bored listening to it.
Yes, sometimes I literally want to listen to electrostatics or expensive planars again, I go and take them from my office neighbors. They usually just lie on the shelf and are not used in their work
I listen and sort of like a wow effect, but then, after a few days of working and comparing not only music but also the sound for mixing recorded from expensive microphones, I get bored again.
I love natural and correct sound, because I make this sound and mixes myself and I'm used to recording and knowing from the first source what sounds right and what doesn't.
By the way, while writing this, I remembered what a comparison came to me and my colleagues in sound between 660s and NDH 30!
660s seems to be compressed quite strongly in sound literally throughout the entire frequency range compared to NDH 30
I don't know why, I've compared several 660s and they all feel like that.
I'm not talking about the 560 and 600 series .. It's even worse there
And I would also like to add - I have not heard such a surround and wide stereo sound with such a proper separation and location as in the NDH 30 - I have not heard in any other headphones, even very expensive ones, some were close, but not as clear and correct as the NDH 30
