Pros: clarity, soundstage, separation (best I've ever heard), musicality, 32 Ohm, very controlled and deep bass
Cons: fingerprints on the ruthenium shells, long burning-in
Ultrasone Edition 5 Unlimited needs some serious burning-in. They sound horrible at the beginning but after about 30-40 hrs they are getting better and better - very open (doesn't sound like closed HP at all), airy with separation I've never heard before (comparing to LCD-XC and even HD800). Unlike HD800 they are very musical despite being analytical. Because of the fantastic separation the soundstage seems enormous, vocals are very natural, highs clear but not overly sharp, bass very deep but controlled. End of the road HP.

New Head-Fier
Pros: Fantastic soundstage and separation, extremely detailed, transparent, lightweight, not as harsh as other Ultrasone offerings
Cons: Price, still a tad on the bright side, cable MMCX connectors are not robust, ugly Edition 5 logo on the side,
I purchased the ED5's to be primarily used as a portable headphones that I could when traveling. Sound quality, isolation, and comfort were the main determining the factors.
These headphones were tested against the several of the flagship closed-back offerings before purchasing.  (  Fostex TH900, Audeze LCD-XC, SONY MDR-R7, Ultrasone 10's ) 
I was initially reluctant to purchase these as I was not a big fan of the Ultrasone sound signature. I also thought the "S-logic" innovation they advertised is extremely vague and confusing. However, after spending alot of time testing these headphones against others they proved to be the front runner by a large margin.
They are bit more forward and less relaxed than the Audeze LCD-XCs. However, The sound is much more transparent, more detailed, more open, and much much more comfortable to wear longer term.
The Sony R7s seem a lot less coherent, and much more closed in VS the ED5's. The Edition 10's treble was extremely harsh when cranked up to comparable volumes.
One disappointment has been the MMCX connectors. The headphones started to periodically cut out because of a bad connection. I returned them to the retailer who had the cables replaced. The problem seems have to gone away. 
Overall because of the sound quality and comfort, there headphones are highly recommended.
