I share the same concerns as some of the other reviews in terms of the cords. For something so precisely engineered on the inside I'm a bit surprised at the lack of strain relief on the cords at the earbud end. I fear that one good jerk (as happens with headphones when you step on the cord or catch it on something) might pull the cord right out. I don't know ... the assembly of cables just feels a little flimsy.
Also the little audio adapter cable that allows you to use it with a straight stereo jack -- when I was unpacking stuff out of the box (which btw all the packaging is very nicely done) there was a little rubbery plastic sleeve on the tip of the adapter cable. When I tried to remove it, it was on there so tight that the barrel housing actually came apart. I mean literally the housing pull right off the tip/cable joint. That's when I noticed that the barrel housing assembly is not threaded. It is just a pressure fit. I'm just stunned by that. Who thought that was a good idea? I managed to reassemble it -- which wasn't easy because it's very small -- but feel they should replace it since it's liable to come apart again. I have been trying to get in touch with AKG customer support and it is not easy to get a live person on the phone. So I'm frustrated with this.
In regard to the location of manufacture -- on the headphones it actually says "DESIGNED in Austria." Mine do NOT say made in Austria. So in your mind you want to picture these fine German engineers assembling these. But they are probably made in China at some Foxcon facility.Read more ›
Before jumping into the sound, I want to make a few comments on build and accessories, which I feel are important to discuss, due to how they may affect the sound and/or durability of the product.
Accessories include 3 pair of stock single flange tips that are very comfortable and well made with a good combination of thickness and flexibility. My only issue with them is that I require a bit deeper insertion due to the shape of the housings and tip length; I can't quite reach optimal positioning. I had some extra Meelec triple flange (trips) tips lying around and these solved the fit issue. Achieving optimum fit smoothed the treble out, improving its tone and realism, while tightening up the low end a fair amount. Another benefit was the expansion of soundstage from left to right and improving imaging. I would like to see AKG offer some dual and triple flange tips of the same quality of their single flanges as the changes I heard in sound were significant for me.
Other accessories include screw on swappable filters (bass, treble and reference). The bass filter is basically useless. It really muddies up the sound, wrecks clarity and timbre and just plain sounds bad. The treble filter offers a very nice analytical sound that is very reminiscent of the Audio Technica CK10 and is overall more neutral. The reference filter, which is my preference, slightly pulls back on the treble presence, while adding a very satisfying bass presence. The build quality of the housings and filters are excellent and beautifully crafted. I love the smart screw-in mechanism of the filters. The housings are surprisingly small and tastefully minimalistic in overall design.Read more ›
In a different league than Westone 4, Schure 535 and Sennheiser IE80s but not by 2x (i.e., law of diminishing returns: price vs performance.)
The downside? Price, cabling (seems delicate/not user-replaceable) and therefore IEMs that you might not want to use in a mobile context for fear of breakage.
November 2015...I now owened 14 months and the whole volume control piece broke off. I contacted Amazon and they replaced even though they were out of warranty. They are not that well made so be careful.
This pair of headphones are probably the most most realistic and unbelievable ones. The sound is just live like. I even like to purchase another pair just for the purpose of collection.
If you had the budget, and if you had enough budget, get them.

Well I spend lot of time and money in my hifi journey started with Sony SRS X9. Today I have settled with Chord Mojo-> AKG K812 and Fiio X3/Mojo-> AKG K3003i.
For me K3003i sound better than everything except AKG K812 due to sound stage etc. I generally does not miss K812 when I am listening to K3003i. However I sometimes find K3003i bit too bright and fatiguing. Ear tips does not fit well to my ear so I have fit Fiio EX1 tips. May be I should look for something else. Isolation is not bad
