Headphoneus Supremus
Rather than burn in, I would suggest trying different ear tips. I spent over a month on SE846 and have about 30 pairs of various tips that I will never use after I settled on Westone Startips. It's remarkable to me how the material and the fit of the different ear tips can have such a dramatic effect on sound. My expectation going to the K10U from SE846 will be slightly more treble extension and soundstage, but a slight loss of sub bass. I also don't have any expectations of whether I keep both or just reduce down to on IEM. I am starting to like IEMs more than headphones though so I may be giving up on full size cans.
