Does anyone else have a rattle insider their K712s? Not from sound vibrations, but from just tilting your head a little. Like thereās something loose knocking around inside?
It kind of sounds like the driver is not securely held in place and is shifting slightly when I move.
It sounds like a piece of something broke off on the inside. You definitely shouldnāt be able to hear stuff moving around on the inside of it.
Definitively donāt rear a rattle or anything. The cup housing is kind of ālooseā in the structure, but I only rear anything if I shake then outside my head. For checking what @marcgii said, try taking off the pads and looking at the driver. You just need to rotate until you hear a click, and they come off pretty easily.
Hi everyone! I bought both the akg k712 and the k702 during the 4th July sale. I have a question for k702. There is no official forum, I donāt think there are many people owning this. This is how I am hearing:
Hmm, Iāve only had the k712 and the soundstage is pretty wide but not very accurate. Now i could be wrong but a wide soundstage on a lower fi headphone isnt gonna replicate the track all that well. The parts that are gonna be thrown wide may not sound detailed compared to something being thrown more intimate. Listen to āSpill the Wineā by Eric burdon and let me know how the soundstage/imaging/ instrument seperation and detail sound
I had both before and ended selling them. I decide to rebuy them for the sale price. The k712 sounds wide and more coherent. Coming from beyer headphones imaging is not as good lol.
Two things to consider:
First, is the connector on your amp ok? I had a similar sensation one time because the 1/4" Jack was kinda wobbly and the stereo sound was kinda āunder amplifiedā, and anything center was better to hear. I guess since everything more centered comes by both connectors, although Iām not 100% sure.
Second, are you hearing thins in multiple songs/recordings? I remember my utter shock listening to Red Hot Chili Peppers āDani Californiaā on both the K712 and HD58X for the first time, it was that strangest āball of soundā.
Now, considering both of these cases donāt solve this, maybe youāre suffering from the inaccuracy described by @Bmn1251. I donāt know about the K702, but my K712 are not that inaccurate, but you will kinda see come āconcentrationā of the instruments on the left/center/right position. To evaluate this, Yosi Horikawaās āLetterā or āBubblesā are a great test tracks, although they do get a little on my nerves as Iām not a big fan of AMSR like stuff.
Thank you for the reply. The adapter is good, the imaging and soundstage is good. The difference came from using beyer for to long. The akg k702 sounds huge, the imaging is good, but the the added height and width it became a little difuse.
Hello! 
I havenāt been here in a while, I am thinking of getting these as they are pretty cheap (230ā¬ on Thomann) I dont know if Iām gonna be a fan of the mids as they are colored, but there are alot of measurements for these and oratory even has an EQ.
I wanna get these cuz of the soundstage and the comfort and cuz they will definitely fit my head, and they seem to extend in the bass for the most part, and they are cheap, was also looking at DT880 but those probably wont fit my melon sized head.
If I could EQ them to sound like HD600/650 but with soundstage and subbass that would be amazing! definitely gonna try that! 
Donāt know about 600/650, but I own both the K712 and the HD58X from drop, and they are very different animals. The bass quality is very different between both, and I donāt fell like the subbass is more extended imo. The soundstage is in fact larger, and I quite like the AKG presentation of āin the roomā feeling.
Keep in mind they are fairly hard to drive so I recommend getting a good amp. Also, donāt know where you are in Europe but I got mine openbox in Amazon Italy for ā¬165, so keep a lookout for deals.

If anyone else is having this issue, I fixed it. It turned out to be the articulation mechanism. If you open the back of the driver all the way there are 4 screws in there that appear to tension the articulation mechanism. They were kind of loose and tightening them fixt the popping noise.
I do apologize in advance for the length of his post.
I bought the AKG K712 thanks to Zeosā review in late 2016. I used these headphones on a Little Dot Mark II originally, then fell into a rabbit hole within the last 4 years, going from the Audeze LCD-2C, to my love of the ZMF Eikon and now the Aeolus. I have used a tube hybrid of Xduoo TA-20 then a stack of SMSL SP200 and SU-8 as an amp/dac stack. I loved my headphones at different times and for different purposes.
All this to say that as an early Christmas/Quarantine gift to myself, I bought the Schiit stack of the Magnius/Modius. I bought it for my Audeze and ZMF, but wanted to try on the K712. I had also in the last year bought YAXI K712 / Q701 Comfort Ear Pads https://www.yaxi.jp/product-gallery/k712-q701/. I did not know what to expect but I have just been dumbfounded by the change. Zeos had mentioned he used these pads for his Ether C Flow, I thought what the hell.
Hearing what these headphones sound like with these new pads and proper (in my opinion) amp/dac, is just a revelation. The improvement to the image clarity and layering is just amazing. I do want to say you lose width and depth within the soundstage from the stock pads, but the difference is different and worth it, as well as having improved bass for balance. I have seen people recommend this headphone for gaming, not so much for music. I feel this change makes them such a strong contender for music enjoyment, in their own way of course.
I know this has just been too much to some, but the positive change for my listening experience with this headphone has me really just wanting to gush HARD. I hope everyone is trying to do well, and hope this helps someone out there. I know I am loving this combo, and really has me remembering WHY I love this headphone hobby and what sounds so good.
Interesting, Iāve been eyeing this taxi pad for almost a year now, but I always stop because the stock pads are so comfy. Maybe I will buy it for my can later. Question: did you use the original foam with it or does it have itās own dampening?
Also, 100% agree that this in a good amplifier are excellent for some music. Jazz and big band music is a very relaxing but enough detailed experience, at least for me.
Great question. For my ears, the original foam presses on my ears and makes it uncomfortable for me after about an hour. Although taking out the foam, not just for comfort, but the sound is not negatively effected. At least to my ears. The headphones do not require E.Q. like I had been doing through Peace software, and again, at least to my ears, sound more natural than stock pads with E.Q. Hope that answers your question well enough.
Also love jazz music through these. https://www.youtube.com/watch?v=H7m-5LOU_q8 This sounded amazing on these.
Browsing through forums I came across this piece of info.
Where someone posted in Drop that production has ceased for both K7xx and K712.
The AKG website has a posting from 5 months ago where they have no news on when it will be in stock again.
There are a couple of resellers on Amazon with the prices a bit hiked.
Could be the Covid effect and things can get back to normal at some point or who knows.
Figured I would post this if anyone was interested.
I am thinking of buying the AKG K712, I have an e10k fiio as amp dac. Will it be enough or should I opt for other headphones like the HD 560s? Thanks
The K712 will run on low power sources, they just scale well with a good amp. I like to think a good headphone sounds good alone, they just can get better with better amps. In the case of the K712, going from just a phone/pc out to an amp I noticed a better separation of instruments and a more open/less congested soundstage. Itās like you can better pick the difference in violins, violas, and cellos in an orchestra.
That said, I donāt know how to compare it with HD560s. I donāt own a pair, but from what Iāve read itās a very neutral-oriented, more intimate headphone. Meanwhile, the K712 is more of a warm and spacious headphone.
I would prefer the 560s more for individuals and maybe some vocal-centric or focused in a more limited frequency range. I would prefer the K712 for listening to big-bands, orchestras, and some instrumental jazz.
You should also consider @Dezz post, as it seems this headphone is (unfortunately) in short supply.
Thinking of getting a second pair of headphones (currently have 6xx). Would these be worth getting for gaming over the 6xx or is the difference between the two not great enough to really warrant this? Iām just a casual gamer that plays single player games most of the time. Anyone with experience with both have any thoughts?
I wanted to purchase a pair of these headphones, and I found some heavily discounted ones on Ebay, around the $110-$150 range. They seem to be from China and open box. Are these likely to be legit or bootlegs?
AKG did produce the K7XX, which is very similar in build to the K712, in China. Itās possible the Chinese version (local market) is made there and itās sold at lower prices, hence the heavy discount.
That said, there is no way of knowing before buying. Considering itās eBay maybe you can order it, try to look for the serial number with AKG, and if itās fake ask for a refund?
At this price these headphones are really good. I paid ā¬150 on mine open box in Europe around 4 years ago. Itās worn but still standing, and still my most comfortable set.
