I hear some totally different, the soundstage is big, not as the EX1000, but is big, separation is top noch, as the clarity, I don't need 100 hours of burn in to hear that, so if you hear already some different I don't think that some other burn in can change something, I have also the Nicehk HK6 I I think the bie are superior in every way except the isolation, the HK6 has artificial sound when I switch between the two, after some minutes my ear get used to the artificial sound of the HK6, but not to the separation that is still better on the bie, I use with those the JVC spinfit, they don't isolate well from the but I have strong bass that sometimes I think it is stronger (but when I compared those is not) than the EX1000, and often the sound seems to came out of my head
sorry for the late answer
