Coincidentally, while I'm on this thread, Re: the FSP's fit. Despite the headphones being the best sounding closed headphones I've ever heard, and despite the fact that my ears fit in the small cups fine, I just can't get past the clamp issues. They have restarted my old TMJ problems. Even after four weeks, the way that they fit on my head caused my jaw to renew its old popping, clicking, grinding, and otherwise painful tightness. The FSP's clamp like the an HD25-II, which I'd normally see as a virtue. (They'll never just fall off.) The problem, and this is wholly a personal problem, is the place that the round pad sat at the jawline below the ear. They put too much pressure on the joint.
I have pair of LFF T50rp Paradoxes now that are en route and should be here on Thursday. Comparisons to the FSP to follow.
you might want to try what I did with the FSP. I wore a baseball cap and lowered the cups down about another half inch. This relieved the clamping pressure to a great degree. Yet in the end my ears were too large :(
Let us know how you get along with the Paradox. Quite a different sound from the Mad Dogs, mids as I recall front and center like the FSP. They impressed my quite a bit when I heard them side by side. Are the ones you are getting the standard Paradox?
