It would be fun to get a brand new pair now after dozens of hours listening and compare them to the ones I so carefully burned in.
If anyone tries it (level matched with an SPL meter) and using same tips - I'd love to know results.
All I do know for sure is that any drivers I've tried - both large and small - haven't changed noticeably for me. Fit changes (pads compress, tips get more maleable etc) - but I've never experienced yet a headphone that burns in, and especially something that turns night into day (which is sometimes asserted).
One of the best articles I've read is Tyll's (http://www.innerfidelity.com/content/measurement-and-audibility-headphone-break) - especially the conclusion. I know this is in regard to full sized headphones - but they should show more evidence than a much smaller dynamic driver right?
If burn-in exists, I'm open to having my mind changed - especially if there is some conclusive evidence. But so far everything I've read, and even from manufacturers (Shure says neither their dynamic drivers or BA drivers will change with burn-in), suggests that it's more a result of change to something other than the drivers (pads, seal etc) or it's in our heads.
But if you choose to believe it, and it makes your listening experience better - then more power to you
