AKG Pro Audio K812PRO Wired, Over-Ear, Open Cup Style, Detachable Flat Cable, Superior Reference Audiophile Headphones with 53mm Transducers. Accurate, Natural Sound. Black with Silver

I've got a pair of AKG K702 headphones, but the K812PRO are a step way above the 702's !!! There is no way to truly describe the sound from these cans, but my high resolution files ( WAV, etc.) are a 'new' experience with them !!! Since Amazon has a return process, then all I can say is if you have excess cash to put out for these, then give them a try !!!

I've been using these headphones for mixing pop-rock and filmic-style music tracks avocationally with Sonarworks average correction for about a month. They are very revealing and especially useful for catching glitches and hearing things like reverb tails, inadvertent pops and clicks, background noise, etc. They're essentially bright, and I'm not quite sure how much to trust them in identifying harshness, so I use other headphones such as the Sennheiser HD650s and my monitors to further evaluate those sharper frequencies between 2-5k, and to round out the picture generally. They have an exceptionally wide "soundstage" which may or may not be helpful in the final mix, but is additionally revealing when pinpointing various aspects of a track. I would not recommend these as primary mixing headphones as they can be fatiguing, but they are the best headphones I've used for honing in on individual details in a mix. I think they're quite good in the low end as well, and the overall clarity throughout the spectrum is perhaps unrivaled. These have replaced my Shure SRH1840s -- with which I'd had very good mix results over the past three years, but had read about some problems with distortion in the low end which could be misleading when mixing certain styles (I'm not completely convinced of this assessment however, as, with any headphones or monitoring source, it's necessary to become familiar with the idiosyncrasies and make adjustments to achieve good mixes in any case). The frequency graph of these headphones is all over the place. I wouldn't use them without Sonarworks or some equivalent compensating EQ curves, but, as I've said, they can serve an important purpose in audio production due to their exceptional clarity.

CAVEAT - This review is for Classical Music audiophiles only. Having auditioned the K812 in detailed comparison tests with AKG K702 and Sennheiser HD800, I found the K812 to be vastly superior in 2 of the following 3 categories -- Chamber Music: Mozart's Horn Quintet K.407 shows the 5 instruments in precise laser-cut 3D layout, with the horn in stage center. You feel you are on the same stage with the musicians, or at least in the front row. With the K702 you get the same stage width but zero depth or separation of instruments. With the HD800, the sound is very warm and somewhat distant, as if you're sitting 5, 6 rows from a large stage. Lieder/Vocal Music: Cecilia Bartoli sings "Se Tu M'ami" Bartoli with the piano located clearly to her right rear, the soundstage is close and intimate. On the K702, both the singer and the piano are right next to each other. The HD800 again sounds distant and not laser-sharp like the K812, as if Ms. Bartoli is singing in a cavernous hall like the Met. Orchestral Music: This is where the K812 ties with HD800 depending on your preference for either orchestral details or the romantic sweep of the music. K812 wins hands down in the 3D clarity department -- the opening of "Also Sprach Zarathustra" clearly shows offstage trumpets and foreground timpani. In Mahler's Symphony No. 2 (Second Movement), ample bass is clearly noticeable in the string pizzicatos and the lower strings. More bass can be heard not only around each lower instrument but all around the entire soundstage as well (though not as pronounced as the HD800). The HD800, on the other hand, presents a beautifully balanced sound picture from a few rows back, maybe even higher up in the auditorium. The clarity of instruments, the 3D imaging are both still there, but with the added air enveloping the soundstage and the individual instruments. The bass, even more visceral and palpitating than the K812, never seems excessive and gently floods the entire soundstage with warmth just like in a live concert. Mahler's Second sounds epic in scale on the HD800. Organ music also sounds huge on this headphone! Sorry if I left out the K702 --- it sounds shockingly 2D and flat in comparison. In this category alone, HD800 beats out K812 by a small margin for me. In the final analysis, if I am to keep only one headphone for all times, the K812 would be it. It also happens to be the most comfortable of the 3 for long periods of critical listening.

If you like music produced without electricity, save what the recording process uses, these sound close to being there. They reproduce subtle shadings of tone, pianissimos are sublime, and you still hear everything when everybody's at full blast. I've worn them all day without headache or sore cartilaginous parts of ears. I couldn't be happier with them. (I bought them before tariffs almost doubled the price.)

Great headphone at a good price.

The AKG K812 was introduced in 2014 as a professional headphone and marketed as such. AKG fumbled the ball here and may have brought about their own demise, as these headphones could have been marketed as a TOTL audiophile headphone as well, seriously competitive with Sennheiser's HD800 (now the HD800S) and Beyerdynamic's T1 (now at Generation 3). Unfortunately, this never happened and samples to listen to were thin on the ground. I took a chance with the K812 headphones and they remain my favourites, even more so with a little modernisation using Oratory1990 EQ to bring up the deep bass and take the edge off the treble. IMHO, they are about on a par with the Focal Utopia OG sound wise, and are better constructed than the Focals. Anyone thinking about a TOTL headphone needs to hear these. Buy one soon - they have never been cheaper than at Amazon currently (they were AUS$1546 when I bought mine). Hopefully, AKG will one day produce another masterpiece like this. Sadly their audio design team appears to have been retrenched at about the time of the move to Slovakia of their main HQ. The design team is still doing excellent work at Austrian Audio and Mysphere.

Bien, la verdad es que Akg ha logrado superarse a si misma, de hecho, es el cuarto auricular que tengo de la marca tras los 272hd, 701, 702 y desde luego ninguno suena como suena esta bestia. Diseño: mas o menos lo típico de siempre, evidentemente han evolucionado pero siguen manteniendo el espíritu Akg. Construcción: están muy bien hechos aunque dan la sensación de que se van a romper en cualquier momento, pero no, aguantan bien y se ajustan a la cabeza muy bien, de hecho si te pones otro de la marca notas la diferencia en la presión que ejercen, pero en ningún momento molesta y puedes estar horas sin fatigarte. Los materiales usados están bien con partes metálicas y el resto de plástico que en general son de buena calidad. En cuanto a las almohadillas son muy suaves de material de efecto memoria que se ajustan perfectamente al contorno de la oreja y resultan muy cómodas, es posible que al principio notes las costuras pues están cosidas hacia dentro pero en poco tiempo se doman y ya no las notas. Algo que podría mejorarse es el cable, no por calidad,es el típico de la marca con conector Lemo, sino por la presentación pues no le vendría mal que estuviera recubierto de algún tipo de malla simplemente para que fuera algo mas elegante. También destacar que el conector xlr aun siendo de alta gama es mas pequeño de lo habitual y puede ser un inconveniente si quieres cambiar el cable, aunque se pueden encontrar. Un punto a favor es que vienen con un soporte para dejarlos colgados cuando no los usas de madera contrachapada bastante elegante, cosa que se agradece. Sonido: aquí es donde realmente se diferencian de cualquier otro ya sea de la marca en si o de otra marca pues el sonido que dan es realmente increíble, de hecho ningún otro que tengo ahora mismo me suenan bien, y me explico, por ejemplo, las voces tienen un timbre y una claridad especial, mas natural, el sonido de las guitarras no lo había oído de esta manera, es mas he llegado a oír el sonido de los dedos al deslizarse por las cuerdas de una guitarra española, increíble pero cierto, y ese es el tipo de detalle que caracteriza a esta maravilla de auricular. Como buen Akg que es, el sonido tiende hacia los agudos pero con un nivel de detalle que te deja desencajado, no por que sean chirriantes ni difíciles de soportar sino por la calidad que aportan, siempre se pueden ajustar al gusto de cada uno tirando de ecualización ya que cada oreja es un mundo y lo que a mi me gusta, a ti igual no. Las frecuencias medias son excepcionales, también con un detalle impresionante, y en cuanto a los graves pues bueno es como si estuvieran en un segundo plano pero que se aprecian, es decir están pero sin tapar a las demás frecuencias y como he dicho antes las puedes ecualizar para que suenen mas, cosa que es típica de la marca que parece que dan poco pero están. En cuanto a escena sonora, yo diría que se encuentra prácticamente al mismo nivel que los 702, pero con mas garra, mas caña y mas potencia, con una acústica muy difícil de batir que llenan por completo toda la oreja. Amplificación: bueno aun siendo de 36 ohm agradecen ser amplificados, yo los he probado con varios y la verdad que mejoran mucho dependiendo de cual se use. Personalmente prefiero los de válvulas que los llenan mas que los de transistores. De transistores o normales, probado con, Burson Soloist SL y Schiit Magni, en este caso el sonido es bastante parecido, no así el precio y solo me atrevería a decir que el Burson le da algo mas de calidad a los agudos, pero por lo demás no merece la pena gastarse tanto pues no hay tanta diferencia de sonido, pero con ambos el sonido es muy bueno. En cuanto a válvulas he utilizado el Little Dot MKIII con valvulas Mullard CV4010 y aquí si que la diferencia es notoria con respecto a los de transistores, llenando los 812 , dándole ese empujón que hacen que suenen de otra manera, algo mas cálido, con mas cuerpo y mas amplitud, eso si en ambos casos utilizo como fuente un dac Musical Fidelity V90. Con respecto a estilos de música van muy bien con trance, pop,e incluso con heavy aunque adolezcan algo de graves el sonido de las guitarras es increíble . En fin, estamos ante un producto que vale lo que cuesta, pero que si no te gusta el sonido Akg, mejor prueba con otra marca pues seguramente no te acaben de gustar por el perfil sonoro que tienen, pero si te gustan por ejemplo los 702, estos te van a encantar. Conclusión, gran sonido con un detalle impresionante, indicado para los amantes del sonido Akg.

環境 自作PC → Soulnote D-1N → LUXMAN P-750u 音の細かさや壁を感じさせない音場の広さ、定位、明瞭感、残響音はさすがフラグシップといったところでしょうか 手持ちにあるK712proより上品な低音にQ701より艶のある高音、 下位機種からもしっかり受け継がれているAKGサウンド。 低音・高音に決して埋もれないクリアなボーカル。 一番驚いたのがN5005とK812の解像度がほぼ同じレベルだったという点です。 N5005を聴いたあとでK712proやQ701を聴くとボヤケたような音だったのですが、 同社のイヤホンと使い分けも出来そうです。 K812の音は誰に聴かせても頷くレベルだと思います。 余談 k7シリーズでも言えることですがAKGのヘッドホンは半端なAV機器じゃまずまともな音は出ないです。 ポタオデ用HPAやDAPで聴く場合、DACとアンプ繋ぐXLR平衡ケーブルを逆位相で接続したような、 モヤがかった音・定位が歪んだような音となります。 手持ちのX7 MK2+AM3,5やDX200などでもとても聴けた音じゃありませんでした。あくまでもイヤホン限定 因みにですが、私の年齢は22ですので聴力には自信があります。

My first serious headphone was an AKG and I have always had a bit of nostalgia for the brand. However, through endless iterations, and since the early days of K1000, AKG produced more of the same. I was therefore intrigued when a new flagship was announced, however due to mixed reviews I held off until was able to get this for a competitive price. Straight out of the box, and based on looks and build quality alone, this is my new favourite. Sturdy, classy, understated but at the same time quite comfortable (I say "quite" because it is not exactly lightweight). I read a lot of talk about the cable. While I am a believer in cables and spent thousands on expensive experiments, I believe that a cable can not change the fundamental sound on a system, but rather add subtle finishing touches to a well tuned sound. In other words, yes, it is a rather thin and cheap looking cable but it does the job, it is virtually invisible, no microphonics, no thick heavy ropes hanging from my neck, I have no problem with it. As far as sound is concerned I am primarily a speaker user and my headphones are rather a hobby. In the past I tried many and owned plenty of the flagships - Denon D7000, Beyer T1, Senn HD800, Grado GS1000, several Ultrasone Editions but also played with much cheaper products - including the usual suspects HD6XX, K70X etc. I am not ashamed to admit that I even have a couple of Bose products in my collection for their noise cancellation prowess, a JH13 Pro and other various bits and bobs. Now this AKG - how to put it. I understand the love and I understand the hate. I understand the waxing and the bashing. And the funny thing is - they are all right. If I would have to give a personal verdict I would say: I love it. So you know what to expect from the beginning. After having all of the above headphones I absolutely unconditionally love this one. It is by no means perfect, pleasurable, "audiophile", it doesn't wow me but there is so much right in this headphone that I don't even know where to begin. A lot of people mentioned the balance and yes, it is expertly balanced. There is low range, an exquisite midrange, there is plenty of treble. Now if you have ever heard an Audeze or like the heft of a closed woody headphone, K812 will not cut the mustard for you. But if you think HD800 has a good low end and you are happy with it's overall reproduction of bass, you have to hear this one. Although it doesn't have a lot of low end, it doesn't "hit you hard", it doesn't shake your temples, it is the kind of bass you get, in quantity as well as quality, from a near field monitor in an average room. Also a lot has been said about the distortion below 40Hz. I don't have a problem with this, I don't hear it, I don't think that much can be heard below 40Hz as at that frequency you rather feel than hear. But here's my two cents. In my early days with Dirac on my multichannel setup, I was trying to achieve this perfect curve and the sound was lean and was missing body and true colours. At some point I discovered that by setting up a high pass filter at about 60Hz and allowing some distortion below, I was getting a much more realistic sound. So if there is distortion below 40Hz, I don't have a problem with it, I can't hear it and, to my ears, the low end is just about the best approximation I have heard in a headphone of a near field monitor. The midrange of this headphone is epic. I can go on and on and on about how beautifully voices come through but much has been said about it so I will not repeat it. Plenty of reviews, nobody is denying it. If you like female vocals, you have to give this headphone a try. Krall, Bremnes - bliss. Which is no surprise since AKG have always been masters of the midrange - think for instance K501. Now the treble which plenty of critics describe as harsh, unrefined, raw, bright. My position is that it is all of that. And it isn't. If you come from the "audiophile", mellow, ethereal HD800 or lush T1, it is. And there is certainly a drop in micro detail, resolution, air compared to a HD800. But I always found that HD800 paints a romanticised landscape because in the concert hall or in front of my monitors I hear none of that. Yes, HD800 can dig deeper into the recording. But that stuff I can not hear on K812 (although an exceptional achiever in its own right) was never meant to be heard. You will not hear it in the concert hall unless you are on stage, in the middle of the live performance, you will not hear it on your speakers unless you listen with your ear pressed against the speaker, on a highly resolving system. The word that comes to mind again is: realism. AKG K812 equals near field monitoring. Are the Yamaha's and the Genelec's and the Mackie's sweet and delicate and ethereal? Do they paint a pretty, sugar coated picture? Are they soft, silky, velvety? Is that the sound you are after? Then this K812 is not for you. But if you want the sound of your Yamaha's and Genelec's and Mackie's in a headphone, this is the closest I have heard so far to the real thing. At the right volume (which is not too low but neither too high), AKG K812 sounds pretty much indistinguishable from my speaker setup. I went over and over again over the same recordings, played on many speakers over the years and plenty of headphones, heard in concerts. K812 is not a concert hall experience. For that you have HD800 and HD650. It is not a floor standing speaker experience on some massive class A mono blocks either. K812 is the bookshelf, near field monitor experience. And if you value this rather intimate audition versus the massive concert hall, the big floor stander in the big open space, K812 is stunning. It takes you there, it has no musical preferences, it works equally well with classical, acoustic, jazz, rock, electronic. And it does all this plugged straight into an iPod Classic because it is also the first AKG flagship that does not need massive power to shine, although it will benefit from a beefier and more resolving system. It is a bit bright but near field monitoring is bright. It is a bit unrefined but electrical guitars are not refined and try to play Metallica on HD800! However, having said this, listen to Bremnes' voice on HD812 and tell me if you have ever heard a headphone, any headphone near this price range, that can do a better job at bringing her to life. It might work for you or it might not. If you think Benchmark sounds lean and harsh, if you can't stand a Mackie or a Yamaha near field monitor, if you are a Berilium tweeter fan, it's probably best to skip this headphone for the high end Focals or Stax 009. But if you value near field monitoring, if you want to hear it true rather than pleasurable, K812 might be a revelation. I can only hope, with all the rumours going around, that this is not AKG's last flagship.

Sonido de calidad, capaz de dar muchos detalles de la música que se escucha, jazz, clásica, vocal. No son pesados ¿Tal vez la diadema-soporte de la cabeza podría haberse mejorado? Y en relación al proveedor, Clever Shopping UE, muy bien, servicio impecable.
