32ohms. Massive deep bass in the 60Hz region ... way too much for my taste, but then im used to open headphones like k7xx and 6xx that are way softer in that freq area. A little hyped up treble too, but not even close to the incredible boost in the deep bass area.
I haven't finished with brake-in time yet to properly judge them, but preliminary it seems to me that they're not a good choice for mixing -unless- you've been using them for long time to really know them well and auto-compensate for the strong bias towards bass. They sound great as tracking phones though.
Really comfortable.
tim273yes, now I know... but they had to be driven from an ipad besides my audio interface, so I had to choose the low impedance.
Thanks for the information, everybody seems to agree that the 250 ohms are much better balanced.
Maybe I'll buy the 880 to do mix work.
Do you have any information on them?
