Well Andrew:

He’s definitely right about one very specific thing 
But why is it like that 
Well, these, with all the frequency curves fetishists
, so “oblique” and “wrong” measurement data, make absolutely sense
, – because exactly these headphones (and the most GRADO’s in particular) have in common:
An extremely stress-free reproduction of purely acoustic music, this type of music is presented in such a natural, precise, airy and wide manner that even the Susvaras, Utopias and T&A Solitair’s of this world have problems to convey this sound quality. (tried them all on a Audiovalve Solaris)
Even the deepest note of a bass guitar, drums, timpani or wind instrument is reproduced precisely

So the talk is of the fact that these cans cannot reproduce bass perfectly, actually stupid stuff. (we still taking about acoustic music)
Instruments and voices, fade out in the room, just as it has to be.
They present the whole thing with such a “sound authenticity” that for lovers of THIS music genre it doesn’t even make sense to pay 3-6 times the price, especially since Planar Drivers just can’t manage this kind of naturalness with such music genres
.
However, as soon as any electronic instruments come into play, the music recordings are relatively cheap (the case in 70% of the mainsteam productions), and these should also represent an overloaded and fast sequence of vocals and instruments. –
I can / must confirm, that the critics of these headphones are right, the headphones are stinging in the high frequencies at times and / or are overwhelmed
.
Well, that’s why the Focal’s, Hifiman’s, Audeze’s … exist
.
Until a price structure in areas in which I could buy a small car
.
And with so many mainstream recordings, it makes a lot of sense to buy a DSP-controlled bluetooth headset anyway, as they are then able to put a decent portion of icing over what is presented, making the whole thing bearable.
PS .: there are special headphones for almost all genres of music but no “Jack of all Trades” (not even for $ 7000) at least not in my eyes / ears.
Happy listening everyone
