To answer your question, the NDH 30 has more resolution and clarity, a bigger soundstage with more depth width and height and more precise imaging. Technically it is at least a class above the 660S2. However that does not necessarily make the 660S2 the inferior headphone, just a different sound signature. The 660S2 is warmer and darker sounding, more intimate and a bit more musical, however for how ridiculously accurate the NDH 30 sounds, it still manages to sound very enjoyable and musical as well.is there somewhere a very accurate frequency curve of the ndh30 headphones?
My other question is, technically (resolution, soundstage, imaging, clarity) how does it compare to a Sennheiser hd660 s2?
That’s a very interesting, and mostly very good review, much of which I can agree with. However, the thing which I find the most striking about the NDH 30 is the fact that they are so engaging – quite the opposite of what he thinks. But, to be honest, I’m not really surprised by his conclusion. He’s from Sonsrworks (or used to be there) and for them the HD650 is still the King. In other words he thinks that the 650 is a better headphone technically and is more engaging than the NDH 30. That’s where he’s coming from, so draw your own conclusions…….
I find it kinda ridiculous to think the HD 650 is technically superior, it has a nice mid-focused sound and with Sonarworks you can make it sound very flat. But technically it was always on the lower end of the scale, with higher end gear the veil tends to clean up a bit but still. As it stands the 660S2 performs quite a bit better with more resolution, a bigger soundstage, a relatively deep reaching yet tight bass. Whereas the HD 650 had minimal bass and if you forced extra dB's in the bass region it would just muddy up the lower mids and it also had that honey'd up mid-range with mediocre detail retrieval.
And then we have the NDH 30 which is technically far superior to both, at least to my ears, no comparison surely.
