I am getting great audio reports from pretty much anything I have tried
with the k3 so far.

I bought on Ebay a very cheap skype headset. This is sounding really
good, not too much base and plenty of Presence, Nice clear 'DX' audio.

For a desk mic I tried an old computer desk mic that came with a gateway
PC years ago. Once again I am getting very good reports with this. I
have not tried any TX EQ settings other than flat.  

My home brew headset is based on a beyerdynamic headset and a copy of
Icom's hand mic circuit implemented in place of the original noise
cancelling dynamic insert. 
This has worked very well for me on a variety of radios, it also works
very well on the K3 

All of these connect into the mic in jack on the rear
I don't think there's is any magic here, pretty much any electret
condenser mic is going to perform more than well enough for excellent
SSB audio, No need to buy into any hype.
Mic housings with smaller openings will tend to have more Low frequency
roll off 

It's nice having everything connected via the back as it leaves the
front panel clear, since I Like changing things around I have routed all
the rear panel audio,ptt and keying lines via a 1/4" half-normalised
patch panel. This allows me to swap mic / change key etc with ease

I have a 250 in mine and find it very good it is wider than 250 but this
does not appear to be a problem. I have not tried the 200 however I am
entirely happy with the current level of performance which during the
CQWW and CQWW160 cw contests was very noticeably better than the icom
7800
