My view on the measurements.
I will use the 'compensated' ones as these look more intuitive (speaker, amp, DAC alike)
What I see here is about +5dB of 150Hz hump. Sure it could be +4dB or so using another target but this is too much of a hump.
I kind of agree with Dan Clark that a small hump (max 2dB or so) will give sound a bit of 'thump' or 'power' to the sound. Too much is just 'bloat'.
It is true one can get used to this and call it 'full sounding' but with proper recordings it will sound too 'fat'.
On the 3kHz peak. I disagree that this is like an ear resonance. It is waaaaayyy too narrow to be just that.
It may not be as obvious as it may look. Reason being it is narrow and preceded and followed by a dip. The way the hearing works the peak thus will not register as too loud and it will 'mask' the dips before and after the peak a little.
That said... in the 3kHz range there are mostly harmonics present and these have their fundamentals much lower. When different notes are played the harmonics around 3kHz will vary 8dB while the fundamentals are pretty constant. This will make some instruments sound a bit weird. Not necessarily 'bright' (which one would expect from a wider peak).
Due to the measurement method and target we can assume that in general there is some sharpness (8-15kHz) as that seems elevated. Sadly, because of the measurement method, we cannot say much about the treble quality. Different methods or trained ears will be needed.
This clearly will not be my headphone, also not with EQ as one cannot undo what this headphone does.
I can see a LOT of people liking this headphone because: It is SONY (reputation, deserved or not), or because of its looks or price (so it must be good) or because of the U shaped response (bass + tizz) that some desperately want. It may even sound great on some older rock recordings that lack bass.
Yep, the consensus here is that measurements are everything. Interpreting them by just eyeballing it or matching it to some 'averaged' target from specific test fixtures is not as clear cut as it seems to be.
Having measured, auditioned and heard well over 100 headphones and having been in this audio-electronics business (professionally and hobby wise) for over 30 years I will say that measurements of headphones (and speakers in rooms) are indicative at best and NOT hard science like DACs and amps despite some people insisting it is an exact science and the only truth.
