HD650 a tiny bit too airy?
Playing around with EQ I figured out the only thing I would really change about these headphones is the bass -to nobody's surprise-, and the extreme top end as well. It's the only thing I find just a tiny bit offsetting on that region from these headphones.
It's mostly irrelevant listening to music casually, especially when blasting these at loud volumes, but the effect is noticeable in my productions and mixing/sessions, nowadays all my projects roll off above 15kHz or are considerably attenuated +10kHz, and it doesn't sound like a problem in these headphones, and surprisingly neither they do in other playback devices much. It's almost like the rest of the spectrum is sufficiently balanced to make me think "hmmm, it's only missing some air, the rest is fine". I attached 3 screenshots from the spectrum analyzer of 3 different choruses in projects of mine so you have an idea of what I'm talking about.
Let me know your thoughts on these and whether or not you've had a similar experience, but especially from other musicians and audio engineers.
