The Ori is a Fostex T50-RP that has been modded by Zach and also tuned by him.
The bass is really fun and it has a little extra thump , because that is how Zach tunes them. The mids are still pretty good and the treble is decreased just a little, again it is how Zach tunes them.
They are wonderful for acoustic music and blues. they need a little current to make them sing their best and for the bass to sound its best, the Rag definitely provides that.
So strong bass, and a darker treble, though not too dark. If you do not like the tuning, Zach offers to tune to your request 1 time for free, say you want less bass and more treble or something.
Lots of different woods to choose from for the Ori model...you also pick the color of the sliders and the headband that you would want. Comes with two different sets of ear pads.
Could probably find a set on the used market for a pretty good deal.
The build quality is wonderful, but they will be heavier than the hD650 and the HD800....not sure how heavy your HE560 was.....probably heavier than that also.
Same drivers as this headphone....you could by something cheaper like this to see if you like it or not.

Some say it is too much money for a modded Fostex TR-50....but they sound fantastic. It is the same headphone , the TR-50 that Mr. speakers mods for the Alpha Dog and Alpha Prime
I think I have covered everything.
