i saw them(along with 860 and 840) at the hong kong hifi show over the weekend.  actually i'm not so sure if it's called performance 880.  i don't know much about them. nobody was around me.  guess they were too busy helping the other guys with the edition headphones.  the guy used to answer me question at the show every year left ultrasone(dealer/distributor) so i don't have much information.  but the 3 models all have detachable cable.  the one with 880 has a cable like the one with microphone from signature dj.  and the cable adopter look a bit like the one with the signature headphones.  the sound, i don't really remember because they were using a dap(ak120 maybe?) and music(kpop?) that i'm not familiar.  here are some photos
