The AKG K-712 drivers are not the same as the previous K-Series headphones. I feel better having said that. Fhew. I don’t want to bore you with more specification information in the beginning of this review, so I will start off with the Conclusion first. You can read the details afterward. That is just how I roll…#likeaboss
The End Credits
AKG has created a mini masterpiece in my opinion. I enjoy this headphone a great deal and it will become my go to reference headphone for the time being. She is slick, sexy, well balanced and crazy comfortable. Top that off with an unpicky nature when it comes to amplification and you’ve got yourself a real winner. I consider this headphone one of the best multi-media headphones produced lately. I can’t believe I am saying this, but this AKG headphone can sound great with rock and moderately bassy tracks. If you are a fan of the Hifman HE-500 or HE-400 but are a bit troubled by their fatiguing sound and weight, grab yourself one of these K-712’s or at least attempt to demo one. You will not be disappointed. The K-712 is buttery smooth and soft on the low end with more quantity than the previous K-Series headphones in the past. AKG has done a great job and this headphone is a gorgeous testament to how well a headphone in the mid-tier price range can sound.
I realize it is hard for people to accept the possibility that an AKG K-Series headphone can produce a solid low end. I know…crazy right? I was pleasantly surprised to hear the K-712 output very nice low end quantity with proper EQ functions in the mix. Certainly a few steps up in quantity over the K-701 or similar models. Don’t expect a Denon D-1100, D-5000 type low end or anything basshead worthy, but do expect a more than sufficient, well balanced and divinely executed low end. It seems the K-712 is a bit voracious when it comes to voltage despite its lowly 62ohm Impedance rating. I’ve noticed that with more power on a higher gain, the low end will reveal it’s true nature. Directly fed by my ALO International on High Gain, the experience is sufficient on the low end only with proper EQ of my portable source. Without it, the headphone sounds like a typical AKG headphone: lean on the low end and a bit thin overall. However, driven by my Burson Conductor SL the experience is exceedingly smooth and more than plentiful for me in sheer quantity so long as my source is capable of pushing solid low end. Broad and stark neutral, this headphone is a great contrast to something like the Audeze bass experience, which is much more focused and in your face, less broad sounding and much harder on the slam effect than the K-712’s softer tone.
No one quality in this headphone stands out from the rest. V-shape is totally absent from this headphone, which to me is a great thing. I hate recessed midrange or either of the three major quality factors ( Bass, Mids, Highs ) appearing more prominent than the other two in a physical sense. This is a very linear experience throughout the spectrum, very flat and well balanced sounding. Exceptional for multimedia usage and gaming in general. Dare I even say this is one of the best gaming and media headphones I’ve heard in many years.
Vocals seem a bit loose and panicked in their upper most areas, nothing serious and for the price I consider them very well set up. Not too relaxed but also not truly forward. This is not a common trait for a headphone with a stereo image that tall and wide, typically this type of sound stage experience results in a more relaxed and pushed back vocal experience. Somehow, AKG avoided that and pushed the mids upward just enough to blend seamlessly with the Bass and Highs.
Tracks like Jamie Foxx’s – Why off his album titled Intuition result in an unexpected smooth and balanced sound signature that I was not at all ready for. Upon first listen, I expected this headphone to be a clone of the K-701 with some minor tweaks, but was pleasantly surprised when that midrange and low end seemed more powerful and tonally balanced together. Certainly not as aired out or separated as the previous models before it, however the K-712 seems to produce exceptionally smooth and buttery bass along with the majority of the midrange. My only gripe is that the upper most area of the midrange seem a bit nasal to my ears, producing a little too much bite and hiss on notoriously sibilant tracks you might have in your collection. If the track is sibilant, the K-712 will sound sibilant. It is not at all a forgiving headphone when it comes to the upper midrange and above.
The major flaw of this headphone is certainly the upper region. I find it too unforgiving and too true to the track. It will sound sibilant and harsh if your track happens to sound that way, so do not expect a forgiving experience and soft natured upper regions on his headphone. Despite that, the highs are very responsive and require an excellent amplifier to properly tame. Properly tamed by my Burson Conductor SL using the 9018 chip, a Dac Chip that is one of the most beautifully dynamic and forgiving on the upper regions piece of equipment I’ve ever experienced, the entire K-712 journey on the upper region ends up inverting itself into a relaxed presentation. Summed up, use an amplifier known for stereo imaging qualities and very smooth, forgiving highs and you will be rewarded with a highly dynamic and tonally balanced experience throughout the entire audio spectrum Beautiful. So beautiful in fact, I stopped using my Sennheiser HD700 completely. I have no desire to use it now, as I enjoy the flavor and overall balanced sound signature of the K-712 even more.
Bonus: Can’t do better than the Burson Conductor SL in my opinion, the amplifier literally made my ears melt with its sheer awesomness and ability to mesh with anything I tossed at it. From the LCD-3 to the K-712, the Conductor SL made everything sound great. Everything.
