My name is grizzlybeast and I'm an audioholic.
Beyerdynamic Custom One pro's
On my pair, there was no thumping bass. You had to EQ the lower end like crazy (ie. Bass increase to 20 on Rockbox) to get a nice bass rumble. Uneq'd, they just sound really meh and the highs are tinny.
That sounds nearly the complete opposite of the sound signature of the XB500. I'd put my money on them being defective or fake.
On mine, without even using EQ, the bass was so strong the headphones literally vibrated on my head.
I May sound odd, but, hd650, here is why. In comparison to my k701 sound is so flat and so "in head" that I can not stand it, and that head band and padding, it's putting far too much preasure on my head and paddign is a bit punctual, so as result it was a real pain to put them on, for some longer sessions, Anyway they are in the box for good, need to get rid of them. Hd800 is obviously in oposition, great hphone. k701 are also great in comparison to 650, will miss them, but my younger brother is looking into these, so I have to say bye to them and let him enjoy great presentation, air fantastic hphone ...
