By miles the AKG k701 is better than the Sen HD650.
The AKG is much more dynamic, transparent and extended. I find the 600 & 650 headphones to be thick and dark with little headroom.
If you want to hear that HD650 "sound" done well try the Audeze headphones which have a thick and dense sound, but not at the expense of detail or dynamics.
