Pro Audio K271 MKII Over-Ear, Closed-Back, Professional Studio Headphones, Black (2470X00190)

Straight out of the box these phones are "meh" at best - slight bass and tinny mids/treble but very comfortable. I can take or leave the auto-muting. However it can be easily defeated by rotating the headband trigger out of the way. After about 4 hours of moderate volume play they began to "fill out" nicely. A couple of 4 hour moderate volume days later they sounded pretty good. Better yet with the supplied velour pads. Unfortunately both sets of supplied ear pads are too shallow for me. Dug out an extra pair of Shure alcantara pads to find out if they'd help the situation. Sure enough (no pun intended) the slightly extra pad depth increased both my personal comfort and improved the sound stage. Bass and overall balance is greatly improved. Be sure to remove the foam discs on both drivers when using alternate pads with sewn in driver protection. The ambient noise reduction of this closed back design is pretty good. Different (better) pads and a few hours of moderate volume run in turned "Meh" into "Okay!" Try a pair of round Brainwavz hybrid pads for even more comfort and sound stage improvement than with the Shure alcantara pads. YMMV. Enjoy!

I picked up a pair of AKGs back in November on sale for $[...] to substitute my Paradigm Monitor speakers while I am not at home. After much scrutiny, I picked the AKG K271 MKII; while it is not the most recent model released by the company, it offers the same sound quality and more. To put it bluntly, I was extremely satisfied. To start, the most important aspect of headphones (aka cans) of this nature: sound quality. The general consensus is that AKG is very muddy in the bass while being very bright on the high end. While the stereotype may be true in some models, the headphones are fantastic at covering the entire spectrum from muddy to crisp. I will have to agree the highs are bright, but nothing that can't be fixed to your liking in an equalizer. When I first started listening to them, I experienced the "wow, I'v never noticed that cymbal hit before" symptom. I could (and have) lay on my bed listening to music for hours, completely enveloped in music; the downside is the drop in external perception leads to being very startled by visitors. While an impedance of 55 Ohms doesn't necessarily call for a headphone amp, I picked one up just to see the difference. The PA2V2 was recommended to me, so I emailed the gentleman over at Electric-Avenue.com and bought one. The K271 and PA2v2 pair nicely with each other: boosting the bass and bringing out the sound as a whole, without the amp I had most audio outputs turned very high up. The amp has also been nice to have for all my headphones, but more to come on that in the PA2v2 full review. The build of the headphones is solid and I don't feel like I'm going to break them. I quite enjoy the features that have been integrated into these headphones, from them turning off when you take them off, to a small slit allowing for easy earpad replacement. To begin, the auto adjusting headband: size fitting to everyone, the band being pushed up also enables the sound to come through the drivers. The K271 also comes with a detachable cable, so you can have the long studio cable, or the spiral stretch cable (and you don't have to worry about wrapping the cable around the cans). Lastly, the cans come with leatherette or velour eapads: I personally use the velour as they warm the bass and are very comfortable. After reading through hundreds of reviews for AKG, Grado, Sennheiser, and Beyerdynamic, I cut my final choice down to the AKG K271 and K272. The difference? A whole bunch of accessories, color, and price. The K272 retails at $329 on amazon, comes in black with a 1/4 inch adapter and Velour ear pads. The K271 MKII retails at $151 on amazon, comes in dark blue with a 1/4 inch adapter, Leatherette and Velour ear pads, detachable 3m cable and 5m coiled cable. After about 70 hours of listening these cans have burned in to sound even better than when I first got them, and I strongly recommend them if you're looking for this style. (Note: these headphones can't really be used for DJing) [...].

These headphones simply do not provide accurate bass. I could go on about the accuracy of the highs, the overall detail these reveal that wasn't there with prior headphones I've owned and how comfortable they are during long recording/playing/listening sessions -- and it would all be true -- but I would be compensating, in my opinion, for one glaring and significant shortcoming: that these headphones do not provide either adequate or accurate bass response(I truly hate to say this in print because I am concerned that it will further my disappointment, and I am a big fan of AKG based on past ownership; but if I am to review these honestly in the hopes of preventing others from spending a large amount of money on a product expecting mind-blowing results, it's necessary to be accurate in my review). I record a wide range of instruments -- drums, piano, keyboards, voice, etc. -- using headphones both for tracking and mixing, both as a player and mixer; I also use them to listen to both my final product and commercial music CD's. I have the luxury of having both (2)pair of $40-$80 220M's and (2)pair of $100 K240's to compare these to, as well as my fellow musicians' Sony headphones. My 10-yr-old 220M's have more immediacy and realism in the mids, a more open (pleasing) sound, fuller (though muddier) bass, but less accuracy and detail in the highs than do the AKG271MKII's. My 15-20 yr-old K240's are more open (to be expected, considering they are a semi-open-back phone), with adequate bass, but strained at high volumes due to years of combat as a drummer's monitor phone. My new AKG 271MKII's? Again, while they provide a nice, detailed high, they are very shrill in the mids, lacking the fullness both there and in the lower frequencies. After 100 or so hours of use (break-in?) I am still waiting for the ability to hear/place a bass player accurately in the mix, recognize the fullness of the low-end of my grand piano, or be able to accurately discern each individual instrument's visceral impact during live playing sessions. I sold headphones for 20 years. I have made and recorded my own music for 30 years. I have tried many headphones. These simply disappoint in the lows, failing to accurately reproduce not only the normal pleasing bass of a more 'colored' headphone, but the accurate bass a studio monitor-style headphone should deliver in this price range. Bottom line -- I wish I could get a refund or at least switch to another, fuller, more balanced headphone. It's hard to imagine someone who would be honestly satisfied with their bass response for any style of listening, provided they had heard other headphones with a more balanced sound.

Kulaklık harika ötesi!

At the 80 CDN price tag I got them for, they were a real deal. They are comfortable and sound great. As noted in other reviews,the bias on these is neutral; everything shows up on stage and is measured. Not for the "deep bass" experience.

إنه ممتاز للاستخدام في الاستديو ولمتخصصي الموسيقى لانها تصدر الصوت الاصلي بدون اي افكتات 👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻

Adorei super bom recomendo muiito

Soy un consumidor final particular. Tengo un buen equipo de música por componentes. Y en mi ordenador instalé hace unos años una tarjeta de audio dedicada, la Asus Xonar Essence. La Xonar la adquirí en su día, también en Amazon, tras investigar mucho. No es una tarjeta profesional, no. Pero sí que sus calidades están diseñadas para un cliente audiófilo. Me hice de ella pensando en dar el "salto" a unos auriculares de cierta calidad. Pues tiene amplificador de auriculares que, para unos cascos como estos, resulta imprescindible. El amplificador de la Xonar es un TI TPA6120A2, excelente y capaz de soportar 600 ohms de impedancia con una distorsión menor del 0.001%. La Xonar también tiene conversor D/A de gran calidad, el conversor Digital/Analógico Burr-Brown PCM 1792ª, capaz de convertir la señal con un SNR de 127dBs. Vengo de unos cascos inalámbricos Sony, que han colmado mis expectativas desde hace años. Les tengo mucho cariño. Con los MDR IF410 venía escuchando música tipo rock, clásica, jazz fusión y, sobre todo, me resultaban muy cómodos para la escucha de películas. ¿Por qué decidirme entonces por los AKG K271 MKII? Sencillo: la diadema de pasta de mis Sony de toda la vida se ha rajado tras muchos años. Y aún los seguiré utilizando para películas, si consigo recuperarlos. ¿Y por qué decidirme, en concreto, por este modelo, existiendo una oferta tan amplia en el mercado? Sencillo. Referencias de primera mano, bastante fiables de familiares músicos. Tienen estudio profesional y utilizan esta marca como referencia. Me hablaron de este modelo K271 MKII, por su excelente calidad precio. Pero no lo tenía del todo claro. En un estudio precisan hacer las mezclas con "referencia verdadera". Esto es, "sonidos no coloreados" en graves ni agudos. Si la referencia no es correcta, no es "plana", es "coloreada", crees que has grabado A. Y cuando escuchas el resultado en altavoces o cascos de referencia, "planos", "sin colorear", como estos AKG u otros similares, escuchas B. Algo completamente diferente a lo que se pretendía crear. Sonidos menos vivos, menos atractivos. Eso ocurre porque se graba con referencia falsa. Mi duda era si las necesidades de un estudio coincidían con las mías. Si no me eran más interesantes unos auriculares que realzaran graves y agudos. ¿La solución? ¡Probarlos! Y me llevé mis Sony y otros Bose in ear a un estudio y los comparé con unos AKG. ¡Y claro que coincidían mis necesidades! La calidad es poco opinable. Simplemente, se siente. También los probé sobre la Xonar y más de lo mismo. C A L I D A D. ¿Qué noté? Lo que he notado cuando me han llegado y he podido dedicarles algunas horas a la escucha de mi música y películas favoritas. He redescubierto la música y el cine que me gusta. Escucho sonidos y matices nuevos, información auditiva donde antes no había. Lo que me hace pensar que, dado que los profesionales dicen que “no colorea” los sonidos y yo capto más graves, agudos, riqueza, información, profundidad, separación, la diferencia fundamental ha de ser motivada por la calidad AKG y sus componentes. Amazon, como es habitual. Perfecto. Llegó la caja protegida en un sobre de plástico. Y la saqué sin marcas. Perfectamente nuevo, sellado y precintado. Impecable. Pongo algunas fotos del contenido en caja. Los cascos, con un conector en el auricular derecho de tres pins. Y dos cables con conector de tres pins, por un extremo, y jack estéreo de 3,5 mm, por el otro. Uno de ellos recto cilíndrico de aproximadamente 3 m (que no se aprecia en la foto porque ya está instalado y he hecho la revisión días después). Y otro de espiral de aproximadamente 1,5 m. Así como un adaptador hembra de jack estéreo 3,5 mm a jack estéreo 6,3 mm. Y un juego de almohadillas de terciopelo. Las que llevan originalmente los cascos son tipo piel fina. En resumen, muy contento con la decisión de compra y muy satisfecho con el producto. En estos días que llevo utilizándolos, mi experiencia de uso es inmejorable. Ningún clic, como he leído en alguna revisión. Ninguna pega. Plena satisfacción. Calidad. Ojalá me hubiera decidido antes.
