Lovely headphone. Before arriving I already had a new cable for it and the Oratory1990 EQ settings ready. Stock is a little bright in some frequencies for me, the EQ fixed that and improved sub bass a lot. I have long hair and use glasses so I need to boost the bass to compensate the lack of seal.
The headphone feels neutral and realistic, a very 'honest' frequency response. I can't hear flaws; sub-bass is very adequate with EQ and the other frequencies are tamed as well. It can get exciting or gentle depending on the song. Maybe I miss some of the intimacy in the vocals (compared to Sennheiser) but for live recordings and orquestras it sounds much better.
Comfort for me was bad, I have a lot of hair, glasses and my skull is not small so I suffered with clamping. I already extended the metal part like with Sennheiser and it improved the comfort. Yesterday was painful to use the headphone sometimes, it hurt my ears and compressed my head. The second day is much better but maybe I'll buy a new pad to improve the comfort.
I hope the headphone doesn't explode, I bought it used so I assume it's not a faulty driver, but every time the driver rumbles with bass I fear those tiny little connection will fall from the solder
