The AKG K812 headphones is one of the most comfortable pairs of headphones I have ever reviewed. You can tell they were designed with long nights in the studio in mind.

The headphones can be worn for hours on end without even noticing they are on your head. It’s not just the lightweight design; it’s the superior fit, the way the earpads wrap around your ears, and the feel of the quality parts. I would have no problem editing with these for hours at a time. In fact, it’s easy to forget they are on your head.


The AKG K812 is a durable pair of headphones which are well designed and able to withstand the rigors of daily studio use. If well cared for, they will provide years of top notch audio reproduction.

Most issues with headphones come from the cable. It’s almost inevitable that eventually the cable gets pulled, jerked, and eventually gets a short. No matter how well built the cable is, it’s easy to forget they are on, walk away from the mixing console, and jerk them off your head. But in the unfortunate event that this happens, the cable easily detaches and can be replaced in seconds.

Features of the AKG K812

The AKG K812 reviewed in this article has to be one of the best sounding sets of headphones I have ever heard, and I have heard a lot. So if you’re looking for the ultimate audiophile listening experience. This is the set for you.

Features include extremely large 53mm transducers with an ultra-lightweight voice coil. This allows the headphones to have a frequency response from 5 to 54000 Hz. You may be asking why this matters. After all, humans only hear from 20 Hz to 20,000 Hz. Well, the wider the frequency range, the easier it is to make the parts we can hear flat.

If a headphone has a maximum frequency response, for example, of 20,000 Hz, then it will begin rolling off the volume of the frequencies close to 20,000 Hz. This results in less clarity and less than flat audio reproduction. The same would also be true in the low frequencies. With a wider frequency range such as that of the K812, the roll off doesn’t begin until it is far below and above our range of hearing.

This leaves the frequencies we can hear flat and even, meaning that each frequency, from the highest highs to the lowest lows are reproduced at as close to the same volume as possible. This allows us to hear the music the way the artist intended, with the most accuracy and detail possible.

The AKG K812 offers unheard of dynamics, transient response, and frequency response. The music jumps out at you in a way that simply doesn’t happen with most headphones. The combination of the 53mm transducers, the 1.5 Tesla magnet system, and the ultra-lightweight dual layer voice coil allows for an amazing stereo image which is natural, accurate, and detailed, almost like you are sitting in front of the band.


The sound of the AKG K812 is best described as pure, honest, accurate, and detailed. With these headphones on you can hear things in a mix that you never noticed before, such as subtle ring in the snare drum, or additional guitar parts that were previously buried in the mix.

There is no hype to these headphones, but there doesn’t need to be.

The bass frequencies are reproduced with such accuracy and detail that they don’t need to be hyped. The clarity of the low end has to be heard to be believed. Not only do you hear the low notes of the bass, you also hear the player’s fingers on the strings and can sense the dynamics of their playing. There aren’t many headphones which can do this.

The same is true of the highs, which are crisp and detailed without being harsh or brittle. Likewise, the midrange is clear, vivid, and flat in the mix. Audio professionals need headphones that not only sound good, but also accurately reproduce the audio they are hearing. This allows their mixes to translate well to most any type of speaker system.

Our Verdict of AKG K812 Headphones

While I doubt that anyone who listens to these headphones will be disappointed with their sound quality, the AKG K812 isn’t for everyone. Spending this much money on a set of headphones is quite an investment to say the least, and is likely to be more than most listeners will be willing to spend.

However, if you’re an audio professional whose livelihood depends on hearing accurate reproduction of sound, or if you’re an audiophile who demands the best sound possible, these headphones are a great investment.

I enjoyed reviewing them and would love to someday buy a pair of my own.
