Headphoneus Supremus
Sorry, but I'm a bit skeptical of Ultrasone...I'd make sure you listen first. I've previously owned the Ed8 and the $300 NAD HP-50s are considerably better sounding headphones. Then there's Tyll's most excellent Ed. 10 review.
You know he even gave beats a second chance, so why not the ED 12 or the Signatures. He once quoted that at least the Sig Pro is not totally bad....
