Sensitivity to spikes and troughs varies from individual-to-individual. I am not very sensitive to 10KHz emphasis (like in beyerdynamic DT 880s) mostly due to ear gain, but am quite sensitive to 6KHz activity.
I think midrange would greatly affect genre versatility if it is "off". I personally found the TH600s unacceptable with live recordings.
My D2000s sounded closer to "correct" to my ears from either my desktop setup or the headphone output of my Galaxy Note 2.
