Your K400 has a rubber headband? Strange... Mine has a black leather strip, which one can also see depicted on my box.

Is your leather headband like the one on the K501? From the photos I have seen of the K401, it seems my K400 has the same rubber headband, except it is black and not the dark grey of the one on the K401.
I absolutely love how these K400's sound. This is like the most underrated headphone I have heard. There is virturally nothing about them on this forum, yet they sound fabulous. These are definite competition for my K601. On some music they are obviously superior to the K601...but I am still trying to figure out if they are equal to the K601 on the music the K601's do particularly well (most jazz for instance, along with some types of more ambient rock).
