I though I knew at least a little about the technicalities, but then I saw the Roccat Kave headset and under impedance it says "2,2kΩ + 15%". What does this mean? The headphone can't possibly have an impedance of 2200 ohms :S Confused. 

SAVE MY EVENING EVERYBODY!

Is it a noise-canceling headphone ?

Website for the headset lists impedance as 32 Ohms.  Perhaps a typo?

Since it is a headset, it could also be the impedance of the microphone.

Yes I think so...

I don't know, but it says the same everywhere except from at Roccat's website.. Dont know where it's coming from :S

probably typo or mic impedance maybe. i don't think for a modern headphone they would make an impedance that high for consumer use.

there use to be headphones with 2k nominal impedance during the 70's especially the well known sennheiser hd414 and 424 had 2k ohm models and 600ohm models as well. lot of piezoelectric headphones were 2k nominal and lot of radio and pilot headsets as well. only thing exist nowadays with that high of impedances are electrostatics. even 600ohm headphones are very rare breed nowadays.

How does mic impedance work?

600 ohm headphones arent really all that rare. 
Beyer offers everything they make in 600ohms as an option.
Until recently AKG made boatloads of them.

Well, a total of 3 models still in production (DT880, DT990, T1) can be considered "rare" compared to the vast number of low impedance headphones currently on the market. Even 100+ Ohm is becoming increasingly rare, headphone manufacturers seem to have their own sort of "loudness war" to maximize volume from portable players.
