Hi. I just got my x20i and in comparisson to the x10 i feel like they have a strong peak at the heights at arround 5khz or even higher? between 5 and 9khz somewhere i guess. It almost bites in my ears. Did anymore experienced the same? Is it something which will get better during the time? Or does such a burn in time doesn`t really exist with this pair of headphones?
