Thank you again. Graph has been posted for the K702 65th Anniversary Edition 2014.   http://www.innerfidelity.com/images/AKGK70265thAnvEd2014.pdf   Also, there's a new graph for the K702 and now all the K70x family has been measured:  ...

Thanks. Pretty similar, wonder why my K712 are a little bassier than my K702 65th. Always tought the Annies were somewhere in between the K702 and the K712.

More than 3 weeks and still no graph. It's taking too long and I'm really curious about the k702 65th similarities and differences with all the other K70x family.

Why there's still no graph for the K702/65th?

My k712 and newer Annie have non-angled pads.

So, K7XX is chinese K712.

I fix it... Just opened part 21 and then tried to remove 23 unsuccessfully, but somehow I manage to fit better parts 23 and 20 together, now it doesn't make friction noise, apparently the union between them was responsible for the noise.

Did you manage to solve the problem? I've been experiencieng the same issue in the right eracup... I'm wondering if there's an easy solution.

I believe the K712 is more natural sounding than the K701 and K702, both of these old units were lacking the bass and sounded almost too bright, not a balanced sound in my opinion... The K712 with the 3db bass boost has now a more natural -speaker like- sound with just enough bass without having...

I think both perform really similar, and differences are subtle, with that in mind I have found the famous bass boost (3dB) more prominent in the K712, making it a bit darker than the K702/65th... I believe the Annie has a more defined bass by the way... Both are really detailed and balanced.

Ok, I really don't know if older Annies are darker, mine are late production unit and have the same pads that the K712, so maybe that makes them a little less dark... Maybe the new K7XX will be as dark as the older Annies as they are rumored to have older Annie pads... I'm really happy with my...

I find the K712 pro a little bit darker than the K702/65th, but both are still very natural-balanced sounding... Anyway, I agree, the HD600 were too dark for my taste.

Actually I find the K712 and K702/65th to have a more natural-balance sound... and they look better too.... and the K7XX looks awesome.

It is just a matter of personal taste, both deliver about the same sound quality... I prefer the K7 series sound, and I really like the added bass on the K712 and the K702/65th, if the K7XX turn to be like one of these, then it would be a really nice unit.
