you could search for part number AKG 2458M12010

 
Thanks for link. This is what I was looking for: http://www.thomann.de/gb/akg_k_702_gel_ear_pad.htm
 
Still expansive (combined with outrageous shipping fees) but looks like I save about 60 bucks compare to buying it off from my local distributor.
 
Those gel pads are sure something.

Don't know why this thread is so quiet compared to others... Jeez these are the best headphones below the HD800!!
 
Suppose some secrets are best kept.. :)

Maybe people are enjoying their headphones.

Best under HD800? Meh... :D

So you're saying that the K812 is above HD800?  Assuming the K812 is better than the 712?  I've only heard the 712 so can't compare.

  After about 100 hours the K712 is coming along nicely.  There is far more detail and overtones than with the well used K702.  I could do a comparison with the HD800 & LCD-3 but they both have custom cables installed and it wouldn't be even close to a fair comparison.  
 
I'd love to make up a custom balanced cable for the K712, but that's down the road a bit.  FWIW, Moon Audio has Dragon cables for K702 & K712.  The Silver Dragon V3 does amazing things for the LCD-3.  I'm sure it would be fabulous on the K712.  

Really?? far more detail? From what I read the K701/K702 are analytical/detail monsters and the K712 more on the warmside..

I just did a comparison with the K702, K712, HD800, and LCD3(f).  I used TRS single ended output from my Eddie Current 445 amp and stock cables for all but the HD800 which has a hard-wired Wire World cable, (with a single ended adapter).  I listened to CD's Vivaldi Farwell Concertos, and a Haydn String Quartet.
 
You are right the K712 does sound warmer compared to the K702, but the detail in the treble is still there, IMO.  The treble detail is more obvious in the K702 because the midranges and bass are somewhat lacking.  The K712 had a richness, depth, and saturation that the K702 couldn't match.  
 
Comparing the K712 to the LCD3(f) was again a step up in bass extension and a richness in tone.  The LCD3(f) had better separation and detailed instrument placement, but the difference was not as great as I would have expected for the $1,400 price difference.
 
The most surprising finding was that the K712 sounded most similar and actually better than the HD800.  The K712 had all the detail of the Senn, AND better bass extension.  There was a kind of subtle musical quality to the Senn that was perhaps better than the K712, but the separation and detail were clearly better on the K712.

Hope this helps anyone out there thinking of getting into a K712.  I can't see how that would be a bad decision . . .

Great! Your review makes both my HE-400i and my T90 better headphones than HD800

More detail then the HD800? WHAT!!!! lol seriously im must try them, Im looking for a detail monster but also very important flat sounding (very flat sounding for mixing purpose) do you consider them to be flat with no noticable emphasizes at all?

I think K712 would be good for mixing.  Planar type headphones, Like HE500, may be better.  They are heavy and may not be all that comfortable for long studio sessions.

About to trade my HD650s for a pair of these. I know the eternal question is "HD650, X1, or K712/7xx?" so I've tried 2 of the three thus far and I'm ready for the third.
 
What confuses me is how often I hear people talking about how the K712's are harsh/bright/whatever and the HD650 is warm/bassy/veiled, but looking at the frequency charts...
 

 
I'm thinking it's because the K712's 8KHz peak lifts almost as high as the bass hump, but it's not a huge difference and if anything the K712s seem to MEASURE as bassier than the 650's (which is good for my ears). I admit I'm not 100% sure what to expect, though. But that's the fun of trying!

^  I kind of wonder about those graphs.  How long do they burn-in the headphones before testing?  Anyway, nothing veiled or dark about K712, not too bright (but I use an EQ and have high frequency hearing loss).  Seemed well balanced to me.  I did burn-in for about 200 hrs before comparing to other cans.
 
I was going to put a silver cable on my HD800, but decided to do a balanced cable for the K712 instead.

Well burn-in for headphones is snake oil, but I definitely am curious about exactly how that's measured.

Don't think, "snake oil", applies since it doesn't cost anything to burn-in.  (Well unless you consider the cost of electricity and perhaps the modest cost of a burn-in disc like IsoTek.)   Someone would have to do a before and after test to see if there is a measurable difference in frequency response, and that may not be the best test for SQ anyway - I don't know.
