Now I wonder how the k712 will sound. Its supposedly bassier due to the memory foam. Looks beautiful  :)p5

There's a good chance it will just be a rebadged K702 65th AE, but I don't think anyone knows for sure yet! As far as I can tell, the 65th AE seems to sound pretty similar to the K701 graphs on here, but with the advertised additional bass. I've read it's bassier than the Q701. Sounded pretty good to me, but that midrange bump is surprisingly nasty sounding depending on the music.

i've played around will modding the front of the K701/2 in numerous various ways.  including trying tape to diffract and rolling different foam from the Beyer and the K271mkii.   lots of potential here.

Yup. I think so as well. I tend to like them when I get them sounding close to what I want it to be. Still playing around with them to wait on my final verdict/say on them.

Yes and yes! That bump around 2KHz is very prevalent on the AE, though it seems like it can be modded to fix that. The trick is finding what works best...I'm still experimenting a bit, though I haven't had much time due to my recent move.

I was getting interested in the new ones thinking akg fixed the tonality with a pad change. Oh well, I expected too much. What can I say, the K712 is too sexy. I can't think straight anymore when looking at them I immediately want to fork the dough and get them.

Recently experimented with the 702 since the pads soften bit more after use. Notice I made them kinda tad too dark up top which affected some female voices and limited the air response good amount so I experiment with bit thinner layering of fiberglass with combination of flat polyfill pieces I cut with scissors. Got them defiantly better sounding where the sound tends to "float" around the ears with wider expansion and defiantly even out the midrange to my liking. Gonna leave them alone now. Also seems not only they sound more open now but seem to allow tad bit more lower level of information then they previously had. Still they sound not so well at extremely high listening levels and not a pair of headphones you can rock out with but since I listen to headphones most of the time in moderate levels and quiet environments it's not big issue to me.

After nodding them though these seem bit more impressive headphones than my first impressions of them. My DF's are getting recabled so when I get them back I test these out against my trusty and favorite headphone, my 240DF's. For now these will do.

i think the K701/2 need an amp with increased output impedance or an impedance dongle.  i like 75-100R.  120R is just a tad bit too diffuse and soft in the bass.

the pads on my K702 are squished to hell.  the K701 pads are pretty fresh.  i prefer the K701.

i have my K240DF recabled with HD650 wire and newer K271mkii pleather pads.  it would be a toss up depending on preferences.  the DF does sound a bit more dynamic and groovy a la AD2000.

It looks very nice indeed. AKG knows how to design and style headphones to look attractive. Given it is aimed at the pro-audio segment I hope the price stays reasonable.

Harman is saturating the market with its K701/2 versions...

If you flip that pads, does your preference follow the pads?

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin
