My traduction is : most of IE8 users experience a shift (major or not) in sound distribution over time. My...

The synthese of the post would be : you will pay 350$ for IEM you...
Well, I don't want to be rude, but it is what I call "ears awakening". It is simply that you not used to have this kind of harmonics through your IEM. It takes time to fully appreciate. I had the same when I switched from ES3x.

EM2 vs JH is quite simple : I owned both (ES2 and ES3x as well) EM2 is for some "earsonic fans" the best IEM available on the market. Well it is difficult to describe, but, the difference is clearly the high...

That's not about believing or not. 50 hours is the average time needed to "educate" a ear. That's why the "first" impression has to be considered carefully : you cannot judge an IE8 if you are a Q-jay user, listening music 10 hours a day on MP3 256, and expect to understand and acknowledge the difference with IE8 using flac. You will for sure notice a difference, but the more you'll use it the more you will get used to it. It is all about hear education, some are...

No it takes 600 to 800 hours to your ear to get used to your IEM. Bur in is a complete myth.
UM2 has short high, short mid, and a very poor soundstage, but good dynamic and very clean basses. UM3x are quite different since they have defined highs and mids, but still a clear and net bass, and they have a really wider soundstage. The UM2 for me is a "M" sound : high lack of definition, medium high are present but very short and not that detailled, low medium are weak, and low are powerfull. That make a sexy sound for most listener, but if you really like details...
Well I believe that it is a myth. It the bur in requirement was true, I think that sennheiser would do the burn in in the fabrication process. Who would be silly enough to selle a product with "oh btw, you need a 500H bur in to use it properly!". the IE 8 Burn in issue is a psychological issue : they are not neutral, dynamic, with a strong coloration. No doubt ears need to adapt to a "new sound", and this take time. Everytime I change my IEM it tooks me around...
