AKG K-812

Good

General overall 4.5 starts of 5 just because of cable quality and we will leave room for progress (perfection)

Perfect sound in every way .Excellence response at all audible hearing frequencies. You don't need anything more

Superb.

Best cans I had on my head. Solid construction, premium fit and feel, reasonably easy to drive but very rewarding if plugged into a good source. Exactly as expected. Made in Slovakia. Carrying on the legacy of good old AKG.

Test them if you can and see for yourselves. It's worth it.

Amazing Sound, very comfortable

I came from the AKG K712 and since they already opened up a whole new world of sound for me, I did not expect that much of a surprise. Sidenote: I am using a Steinberg UR44 with the headphones plugged in there, directly. I have not tried a separate amplifier for headphones yet. It is the first high end headphone I tried so far. I am mainly working with EDM music and sometimes listening to classical tracks for which the K812 seems to be designed.

The K812 exceeded my expectations. They did it so outstandingly, I could not believe my ears. Out of a sudden, I was able to hear everything in a mix so crystal clear, as if I could just grab the sounds one by one. The high frequencies are very clean and clear as well. For the first time, I was able to clearly tell if a mix was ruined by the high freqs or not. Though, there is a slight elevation of different freqs at around 2khz, 6khz and between 8-12khz which may be fatiguing over time. Because of that I am not totally able to mix only by the headphones which is a bit of a let-down as they are performing so well.

Therefore, I would recommend to use the headphones for just listening to music or as reference headphones with focus on the mid and lower frequencies.

My Pros:

-Huge and clean Soundstage

-clean (sub)bass area

-very comfortable for endless sessions

-overall superior sound quality

Cons:

-elevated high frequencies therefore sometimes fatiguing

Superb quality mix without speakers!

Perfect sound. With the help of a good pre like the phonitor, and a mono button, you're ready to make tremendous mixes, without any speaker at all. People won't believe you.

Bank on it.
