I just did a sweep test comparing the dt250-250 to my hd600 and I realized that even a well burned in hd600 isn't perfectly matched from left to right, in fact there are more narrow band variations on the hd600 drivers vs my dt250. It just so happens that the dt250s was more noticeable because 100 to 250 hz is something that sticks out as more thickness in the sound of the left while on the hd600 the peaks are so narrow that it is hardly heard in most busy and fast music. Also since the differences seem like they are less than 2db vs around 5db when i first got them out of the box, I really think that burn in is doing its magic here.
I like these cans so much I think I'll also buy an 80 ohm version to complete the collection LOL
