Headphoneus Supremus
I know it is inherent to the closed-back design, and maybe the shape of my ears but I feel they have more unwanted (peaky) resonances, 'ringing' with female vocals and choirs than both my A900Xs and D5000s.
The cups definitely could have been better dampened, if that would be the cause that is....
A very slight lowering of the 1Khz range does the trick, gone is the resonance.
EQing is like magic
