Headphone impedance is generally less important than voltage 
sensitivity.  Most decent headphones will work well with a K3. I mostly 
use a Yamaha CM500 headset (the boom mic also works VERY well with the 
K3 -- simply plug both mic and headphones into the rear panel connectors 
and turn on bias). Before I had that one, I used a set of Sony MDR-7506, 
which works very well too. I'd guess both of these to be in the 100-200 
ohm range.

If you find receive audio level a bit low, check the AF Gain setting in 
the menu and make sure it's on HIGH.
