Same here. I only really notice it when I put them on, but it's annoying. Makes sense that it would be the hinges... hopefully there's a fairly simple fix.
Also, I recently picked up both sets of Dekoni replacement ear pads: the suede ones, and the leather ones. So far I really like the suede ones because the extra room they provide adds a bit of punch to the bass. The leather ones probably need some more time to break in, because with them I hear a noticeable loss in bass and the introduction of sibilance (it actually reminds me of what the Bowers & Wilkins PX sounds like out of the box, before the ear pads relax a bit and seal better). Has anyone else tried these ear pads out yet? I'll take some pics and share more thoughts a bit later.
