I believe that some aspects of breaking in is psychological, but not all of it for sure.
Burn-in is mostly psychological. I’d say probably 85% of it, and 15% maybe physical (depending on headphones). it's rather simple - humans are learning creatures, that’s one aspect that differentiate us from machines. to put it simply, our brain goes through an “adjustment” period. this happens whether it’s physical, visual… or auditory. imagine you visit a place you’ve never been before, or even a place you haven’t seen in a while (whether is a room in a house, school... or even a foreign country), even only after few hours of been in there your perceptions will have changed; after days/weeks/months it will be A LOT different since you viewed the place from the first time. people who say there’s a night & day difference between before & after burn-in is because what they experience it is a night & day difference.
When I went to pick up my D2000 I was on a train back home, and I could not resist giving a listen, so I got them out and plugged them straight into the Sansa Clip. I was mortified - that's not what I expected at all! then I plugged them into an amp (I had an Icon combo at that time), and as I kept listening the sound started to make more and more sense.
that’s all there’s to it, really.
