It's hard to swallow that result but it's great to hear honesty in a product review for a change. Thanks for the review!

Really appreciate your time and effort and above all the simplicity of your review!

The look at the end says it all. It's like you wanted to love them but it just didn't happen. Great review as always Tyll keep up the good work.

You seemed genuinely saddened and disappointed that this was not up to par..Heard a lot of sighs there :) .. one of the more honest & emotional reviews I've seen on a headphone..Respect for your honesty sir

My headphones are telling you to get a better mic!

Great review Tyll !

I'm so excited to see this!

Awersome review as allways

Hello Tyll, I really like your reviews, it's very good to have you giving all the reviews so I know I want before actually go to the stores. However, I really want to hear some reviews about the AKG K420 from you, can you review it sometime in the future? Thanks a lot !

Tyll, thanks for the honest review.

Great video, as always.

It's like you are talking about the HifiMan HE-400. The treble is, in short, broken. And that was 400 euros. 1500 would sting a lot more

Great review you nailed it on the head

Hey tyll, are you planning on doing any reviews of the newer HD 6, 7, or 8 DJ series? They look pretty nice and so far reviews seem positive, but its always nice to hear your opinion.

Glad I put my money on Audeze LCD-X - awesome cans, I'm surprised you haven't reviewed them yet? Awesome YT channel though Tyll:)

found that management on this project prematurely deemed it done while the engineers were still working on it, that's why it fell short. Typical huge corporate management culture.

Well, I'm sorry to hear they have bad treble...I was looking forward to liking these but I don't like the T1s treble either. Have you ever heard the AKG K712? I just bought them, and they have a similar bass response curve to the K812s, but the treble seems (and sounds) very natural and just right to me. I suggest you give those a try!

Any chance we can get your take on the K612 and K712. Your words of wisdom have a huge impact on my last couple headphone purchases.

Akg k812 pro need a good burn in time as all headphones do explains why some loving them and some hating them or everyone would hate them or love them not both Whathifi say you dont start to hear there potential until 100 hours burn in and this is a fact its not your ears playing tricks the difference is night and day I have experienced this since being into this gear since late 80s until this day with headphones and speakers etc The amount of change varies from little to a lot treble smooths out and bass gets deeper and tighter and soundstage really opens up I have proved this to people and shocked in the change of sound when they didn't believe in it I have also come across forums where people never believed and then tried it and stated the change was huge now they are a believer No harm in trying this experiment with a few headphones rather than assume cause you will never find out Not every headphone will change enough to like them but will be a fair judgement on them before sending them back then you know for sure its a good or bad one at least to your ears Akg k712 pro my friend brought on my recommendation he was really dissapointed with the sound out of the box and was worried and didn't believe in burn in at the time I heard them myself already experiencing many times over the years They sounded sterile no soundstage not much bass etc, i said i will burn them in for you I burnt them in for 250-300 hours and the difference was massive Gave them back to him and he could not believe his ears he said there a totally different headphone and loved them Dont be ignorant to it just try it and you will be pleasantly surprised If the k712 pro changed massively so will k812 pro believe me they will

Hello! Thank you for being so honest in your of reviews. Others are blessed as soon as there is something new, not to mention the brand blind people. This shows that novelty and high price does not have to mean that they are better than those been around a while. Self so I was very curious about these until. NOW! I have over the years checked your tests with my own and actually often given you credit for even in my mind right judgment. So in this case so I do not feel that I need to check. What I responded to myself, at a first look, was that the cable and connector seemed cheap compared to the price. But the rest was very solid feel on.

When are you going to do a review of the LCD-X?

Nice review !!! What u think about AKG 712 ?

Great review sir, it comes across as very honest and informative. It's nice to watch an objective review where the reviewer doesn't feel obliged to speak in vagueities and simply blow smoke up the manufacturers arse. It's a shame AKG didn't quite pull it off but atleast they are now reaching

As far as open type headphones go (and i'm a big fan of open headphones) last years i stick to the German Maestro line, had GMP250, now i listening with my GMP400. If you will have a chance - try them out, they probably will end up on your wall of fame.

Tyll will you ever do a review of the Beyerdynamic T1's? I'd like to hear your opinion on it.

Hôpe you can make a AKG712pro review :)

Hi, have you had a chance to give the new k872 a listen? From what I have heard it addresses a few of the issues. I haven't had a chance to hear either myself, but I am very curious as to how they compare to the 812 and also to the HD800S :)

I would like you to show us your favorite sound setups under $300

Good review. Thank you. I just purchased a pair of AKG K240s. They sound fantastic a lower volumes, but if you crank them up, they distort...which was very disappointing. Give me a pair of Bose or Sony Studio Monitor cans any day of the week for cranked up listening. The AKGs are only good for low volume...perhaps a jazz enthusiast would appreciate these.

Can you do a review of the K712, I think it comes closer to the HD800 then the K812??

Truly revealing. Recordings sound different depending on mother tongue or region where they come from. USAmerican different from European or Japanese productions. My Stax SR007 Mk2/SRM717 rig is not that revealing, it makes everything sound pretty and smooth. This review is about personal taste and liking. You do like it pretty and smooth. Camouflaged by expertise and listening experience. Truly revealing about you, but misleading. AKG K812 are the best cans I ever had, purely my personal taste!!!

I think you have to press the little AKG button on the hinges so that it is smooth to adjust????

could you do a T1 review?

Shure 1840 vs AKG K812 vs Fidelio X2 ? I have shure 1840's. If there any point in moving to K812's ?

These or the AKG Q701/K702s? And how does a Philips Fidelio X1 or a Sennheiser HD600/650 compare to them?

I use to work in the recording industry. For years the k240 was the go to headphone. Still a great headphone. The bigger more expensive AKG headphones I was never very impressed with. Heavy, didn't sit right, etc. From my experience I wouldn't fell comfortable dropping big dollars on AKG. They built a great reputation over the years. Now instead of being innovators they just survive off that name they created. BTW listening on a set of Alpha Dogs. They seem to be my go to headphone now when sitting at the desk for long periods of time. Sound good, great isolation and comfortable. If I am in a quiet space I like the hifiman he-500. Sounds very good but they are heavy and only comfortable for like an hour or 2.

Yeah, but how do they handle audio books? ;)

is there any advantage pleather has over real leather? especially for $1500?

A headphone at this price point with no balanced cable?

What about creating a headphone that is based off of the top 10 world famous headphones, using the amplitude median point of each headphone as a zero point, chart the frequency responses and average them accordingly, this is a flagship I want to hear. In actual fact, I don't know why every company doesn't do this with their own products, as it is a method of progression.

Kiss of death, Tyll style

want to know the bose AE

I buy a second-hand k812 just $620 us dollars, good deal.

So sad to see them fail their supposed flagship... This Headphone screams for an MK2 revision, damnit!

I don't understand how such a great magnetic potential can be inside headphones. I don't understand either, how it can be safe. Beacause, I've read some articles on the topic of magnetic induction, which say that high levels of it are mostly dangerous, in short, for human health.

HAHAHAHA that ending.............

jesus .. the sound! talking about 1500 dollars cans

all the reviews are way out these headphones need time 300 hours plus and a high end dac/amp then , only =then will you see how reviling and detailed with the best sound stages on the market still in 2023 not surpassed , truly undervalued by quick judgement with no real time or value

I am a sennheiser fan but it still is sad for me

Sponsored by Sennheiser...

I hope you get a chance to review the Beyerdynamic T 90 I am sure that they have exactly the same problem. Sad that headphones manufactures are playing the specs game .. hyping about fancy magnets and so on. In the end, it's all about the listening experience. I will have to go ortho next time.

=(( expected more from k812

Different ear cups change the soundstage tremendously. For instance, it really surprises me why they would go with leather for the earpads. Yes it gives better bass response but Velour pads in my opinion bring out a bigger soundstage, bring the music closer to you. I don't own these headphones personally but does anyone think if AKG stuck with velour the problems with this headphone wouldn't be their?

Oh yeeee

The greedy Harman management decide to remove the headphone stand on the K872 (same price range)!

this guy doesnt know what he is talking about. they are currently over priced and will reduce in the future exactly like the AKG712 pros. this guy actually reviewed some skullcandy headphones and said they sound good. really?!

Are these headphones really that bad?

When you judge this headphone is it burned in properly before analyzing it?? I'm talking at least 6 months!! What disturbes me is that you don't mention on what kind of equipment you tested it! Its not designed for a 300 dollar cd player, amplifier if you get me. However I do hope and believe you've tested it on some proper equipment!

Quite cheapy looking for that price.

beyer t1 sounded same.

attention - I had AKG K601 and now Q701. I had constant problems with left headphone. After service fixed it was the same and again it start to do problems.. and now.. its joke - I want to get them on my head, and guess fucking what ? Left just stop playing!! That's whole true about "famous" AKG :)

Ouch! AKG IS FANTASTIC. The k812 Is a swing and a miss compared to the k712. The highs on the 712 are musical and pronounced on every hz. Akg tried to improve what had already been done on perfection. they should have just improved the design instead of the apex sound they already achieved.

Somehow I believe that this guy's been paid by Sennheiser to talk K812 down...

First sad review i've seen, thats too bad. I just wish I could afford the strax and the set up required.

All due respect, what editing DAW or Console are you using these on ? You can't take these and use them with a mixed (colored) recording, then play it back on yet again another colored audio listening device, then you EQ yet again, into these headphones. And then still need to consider using it for DAW or Analog mixing and mastering, as they are meant for non colored editing... And these need break-in time, like any speaker. You probably damaged them plugging them into your ipod or phone,,, These range well above consumer frequencies, and would need some control on the low and high end, using on a consumer device... especially if the audio was not tamed at the spectrum above 15 kHz - 20kHz, Find a sine-wave and reference it using gear made to exceed 20Hz to 20kHz... normal human hearing (but many claim to hear more) and consumer limits for most devices... I would think using these in a correct usage would at least give the definition, but I would low and high pass creating frequency limits. If you don't like them, send them to me !!!! Please,, lol !!! TO Audiophiles, (respect), they do not buy flat responsive speakers, and neither does the basic musical consumer,,, They want EQ'd for consumer use Speakers made with a EQ curve based on tonal color... TO mix master engineers, they want a flat response, non colored listening solution for editing purposes using in an editing environment, using program equipment for this purpose. When they reference using consumer devices, they don't use their studio equipment, they use colored EQ'd devices and speakers to check translation out of the studio....

guys don't buy it now, i guaranty, no i promise you you in a year or two the price with precipitate down to 1000-700$, looking at other past models and history, the pattern of Akg's history will destine this to happen

THD, Noise, Impedance are terrible for the price we pay...... high is quite aggressive.... their fr is quite awesome...but rest of measurement is bit disappointing...

so no bass, no detail and fatigue sound... typical akg I wish I did a listening test before I bought their 702...

How is warm / cold / musical / analytical sounds like? These are just words without physical (evidence based) definition. Totally subjective.

Overpriced pure and simple.

the harshness issue that you think at the high freq is because the radiation varied very strong when you move the earcups.the high freq problem is complete disappeared when you move the cups a bit back and down.please do me a favour and try this.i like your test videos and your spezial knowledge.but this time you have maybe jugde to fast about the akg k812.

Use your own ears. Tyll has "sissy" ears in the upper frequencies. Have had and enjoyed the K812 with no issues that Tyll whines about.

I will Wirte the comment in German and english. Zuerst mal auf deutsch, ich muss zugeben ich hatte noch nie was schlechteres auf dem Kopf als diesen AKG Kopfhörer, ich durfte ihn tatsächlich mal probehören und ein Geschäft und wusste nicht ob ich lachen oder weinen soll! Nein 6 € Xiaomi spielt das Ding fünf Mal unter den Tisch. Ein Beyerdynamic aus der DT Reihe mit diesem Kopfhörer zu vergleichen ist in etwa so als wenn man ein Ferrari mit einem Pferd vergleicht. Der Verkäufer meinte nur, tjaa die sind erst so schlecht seit dem Harmann die übernommen hat, vorher hättest du für die Dinger ein Kredit aufgenommen. These Headphones are the worsest which i had take on my Head. The soundness from my 8$ xiaumi in ear phones are better. And I will not compare These Headphones with the Beyerdynamics or older akgs it is If you compare a Ferrari with a horse ! The salesman Had just said, it normal, since Harmann has bought AKG ! For the old model will Take away Credit to get them ;)

Why the hell don't you get a better mic? Looks really bad when a guy is trying to review 1000$ headphones on a 10$ mic. Just makes you look bad and lame.

Well, that sucks. Most, if not all, $1,000+ headphones are just overpriced and can be easily mimicked or surpassed by cheaper models.

what a depressing review... lol

Wait.. You didn't work these cans, and then you complain about harshness? Fool. Good headphones need to be 'broken in', these more than most. Give it 100 hours of music and it's an all-round world of difference. You haven't even scratched the surface of what it sounds like and that harshness completely fixes itself.

Sounds disappointing :(

First!
