They are very good value
I ordered these to replace my previous set which had broken. I paid about £125 for my originals; these were a steal at £85 so I was a little tense. They arrived when stated, well packaged, brand new, very pleased. (I have of course now seen them for £78!) . These are for use in my home studio. They are “closed back” to prevent the track you are listening to in them from being too easily picked up by the mic’ when recording a second track. (Also know as “bleed” if you are new to recording here, searching for items AND guidance) . (If you are using headphones for editing/mixing, as opposed to overdubbing/recording, then you should also get a set of “open back” headphones, which allow the sound to escape through grilles in the ear pieces, giving a more natural sound for mixing. Basically; get a set of each, and use them as I describe. I have seen reviews on line by some people criticimg the “lack of punchy bass”. These people do not understand the recording process; they are probably just LISTENING to music on band camp or you tube or whatever. You can use toy headphones or ear buds for that! These K271 are a professional tool. The whole point of these is NOT to have a too punchy “anything”! Not TO exagerate the bass, Mid, or treble…..so that your judgements when EQing are based on a sound that is UNBIASED as much as possible. Hope that helps folks. OH! And they have a grooooovy built in “switch”. If you take the headphones off when recording, they automatically cut out the sound! Which means that if you put them down on the desk or whatever the sound will NOT accidentally be heard by the mic…because it has been stopped. Far out! ( man!) Hope that info is good for somebody, and good luck in all you do. Steve.

Great for me
I had the original version of these headphones for many years until they eventually broke, so I’m already familiar with how they sound. This was a major reason for choosing them over the various similarly priced headphones by other companies (the main competitors for my money were the Sennheiser and Beyerdynamic models in this price range). I use these for recording, monitoring and mixing in my home studio â rarely to listen to music for pleasure, though they’d be great for that, I’m sure.What I’m after is a mix in headphones that’s reasonably accurate when I play it back at volume through loudspeakers, and these pretty much do that job. I’ve used headphones with more low frequency detail and finer midrange etc, but not without spending a few more hundred quid. I find the K240 comfortable, both physically (I have small ears so the cans fit around them; might be different if you have massive lugs) and sonically â they are for me an ideal midpoint between “detailed” and “musical”. (They don’t flatter mixes too much, but aren’t so honest as to be brutal.)Probably worth mentioning that they are semi-open â they can be heard by other people in the room, especially when monitoring at volume; also means they’re not always the best choice for monitoring while recording quieter/acoustic material as there’s a fair bit of bleed.For my mixing needs though, they’re great. I trust them, and that’s the most important thing for me with a pair of headphones. I prefer the new detachable cable on the MKii as well. I know the impedance rating has been changed for these new models but I don’t feel able to make a qualitative comment on that; they can get pretty loud if you want them to, I suppose. Also I went to the toilet and read a few chapters of ‘Red Dragon’ and when I came back from the toilet the headphones were still there, so that was nice, too. Don’t want them running away!For home/project studio recording and mixing, I highly recommend them. I also think they’d be superb for high quality music playback for enjoyment â lights dimmed, glass of malt, nice bit of Abba or Fleetwood Mac or early ’70s Tom Dowd recordings on the hi-fi. If you want to listen to techno or Queen or Dead Meadow late at night in bed while your better half tries to sleep next to you, these aren’t what you’re after. (I didn’t try and do that stuff; I’m just saying.)
Mr PD TaylorARPS –
Compared to AKG K702 and Y50. Revised after return.
I recently bought a pair of AKG K702 open back headphones for listening to my hi fi systems late at night, so I don’t disturb the neighbours. Now, those cans leak like a sieve, and you can hear everything going around you. Very similar to the Grado experience. For the price, they have superb sound. No skull throbbing bass, but a double bass, electric bass and a kick drum actually sounds different.OK, get on with it, you are here for the K271 MK2 review after all…Well, I have owned a pair of AKG Y50 wired over the ear headphones for years, and been happy with them. They block out the sound around you, don’t leak too much and have a microphone, and are aesthetically pleasing. Oh, and they have a bass in profusion. I used them to listen to music when the girlfriend is listening to stuff on her tablet.Now, after a couple of weeks I’ve got used to the sharp detail of the 702s, but I had to pull the Y50s on to avoid hearing background noise. They were indistinct, muddled, imprecise. I needed a closed ear alternative.Having read and watched a few reviews I decided a cheaper pair of AKGs might be in order. The 740s were in the frame, but semi open backed, a close relative of the 702. I reckon well worth looking at, but the backup had to be closed back..OK, the unboxing experience. They come in a box, you open the lid, the headphones are in a plastic bag. There’s a 2nd coiled XLR replacement in there, alternative velour pads and a quality 6.3 to 3.5mm adapter and some paperwork guff. Phew, that was exhilarating.Pick the headphones up, and they feel very light. The earcups are plastic- what did expect, carved granite? Tap them and they sound like solid plastic. Now, do you want something heavy on your head, and do you really tap along to music on the side of your headphones!The earcups with the attached leatherette pads are comfy, I wore them for 2 hours straight without discomfort. The headband barely contacts your head, it’s unpadded, but frankly it makes no difference. Unlike the 702, it’s a more flexible vinyl. The whole thing just happily sits on your head without any heavy clamping. Not had a chance to try the velour earcups, but probably as good as those on the 702. Maybe something to move over to in warm weather.Sound… Really, really precise. Stereo imaging excellent. Percussion comes over really sharp with a solid attack. Bass is there. Not some deep booming like that leaking from a boy racer’s blacked out Audi, real bass instruments. Overall not as open as the 702s, but obviously from the same family.Driving them… They are not ear buds, they have a reasonably high impedance. Serviceable on my Motorola phone, better on a tablet, perfectly fine on my Marantz amplifier at 11 o’clock.OK, the cons, those plastic earcups. If you touch them or catch them on clothes you notice. The earcups are larger than most, but not the whole saucepan lid look of the 702.Advantages. Excellent detailed sound. Accurate. If you want bass, just add a little with the tone controls. Remember you are actually hearing real bass instruments, not something that vaguely wobbles like a darts player’s belly. Unlike the 702s they isolate you a bit.Appearance. Well, the larger earcups and the wires over the top make you look ridiculous. Think cyberman. If you want a fashion accessory go and buy some Beats or the colourful Y50.Conclusion. Better sound than the Y50, but not as well built. If you want a better sound, and have a bigger budget 702 or similar.Well, after a few days I returned them for a refund. I found that the earcups were nosy if they rubbed against clothing. Maybe it’s the design of the plastic and their shape that amplifies the noise from every bit of abrasion. The metal shell of the Y50s doesn’t do that. Amazon were doing an offer on the Sennheisser 560S for £119, so I decide to upgrade, and have a different brand as an alternative sound profile. I suspect that the grille design that makes them open backed will be similar to the AKG 702, and won’t act as a sounding board when they run against clothing.

Weight;Almost all AKG headphones are light weight, so no worries.Build Quality;Really better build quality, than it’s comparators, though it is just hard plastic. Also, the velvet pads are soooo comfyFunction Usage;1. Best for studio recordings ; it’s a closed back!!2. The field emulation is quite great considering its price, so it’s definitely considered for orchestra related music.3. I’m not personally a drummer but my fellow people says it’s worth it!4. Detachable cable, so worthable for live sound (like field recording)Sound quality;Frequency range:The bass is not enough(feels even lower than flat ones), making it too dull. The mids and highs are arguably good.Clarity:The instrument isolation is every clear but lacks volume (compared with DT770 80 ohms) even after using a better DAC.Clarity further decreases when used in mobile systems (including laptops); tried on Dell G15 and Asus F15, both feels off.I don’t personally like this use of mini XLR but, it’s fine (locks perfectly and easy to attach and detach)

Ya existen reseñas muy buenas del producto, asà que me limitaré a dar mi opinión:Sonido.Si lo que buscas son un par de audÃfonos que te permitan escuchar la música tal como fue grabada estos te servirán. Sin ser ingeniero en sonido, músico, ni audiófilo (palabrita muy popular recientemente), debo decir que sà soy un poco exigente con la música que escucho, y estos audÃfonos no decepcionan.Siento los agudos y los medios muy balanceados, nunca me han molestado las fluctuaciones como para tener que bajar el volumen, y los escucho bastante claros. Los bajos son otra historia. Estos sà se sienten un poco flojos, especialmente en algunos tipos de música, no los siento tan “ricos” como en otros audÃfonos ni tan profundos, pero eso para mà no es una desventaja.Al tener un sonido bastante plano me han permitido escuchar algunas sutilezas que no habrÃa podido con audÃfonos de menor calidad. Por ejemplo, al escuchar dos interpretaciones diferentes de la misma pieza de guitarra puedo escuchar la diferencia entre ellas no solamente por la manera de tocar del músico, sino también por detalles como si está usando las uñas o los dedos para tocar, algo que si bien no me es importante, es interesante notar.Para géneros como rap, electrónica y metal no me encantan. Los bajos no suenan tan divertidos ni profundos y a mi parecer a los medios y agudos les falta un poco de “ataque” que hace muy disfrutables estos géneros en otros audÃfonos.Comodidad.Aquà flaquean un poco, la banda que se apoya sobre la cabeza es una tira de vinil un tanto gruesa pero muy flexible aunque sin nada de colchón, lo que los hace un poco incómodos después de varias horas de uso. Las almohadillas son grandes, rodean perfectamente mis orejas (que son bastante grandes) y no ejercen mucha presión a pesar de que uso lentes, sin embargo al ser de vinil después de alrededor de dos horas de uso causan que comience a sudar y tenga que dejar de utilizarlos por unos minutos. CambiarÃa las almohadillas por unas aterciopeladas como las de los BD.Portabilidad.Como casi todos los audÃfonos de este estilo, no son NADA portables. Están diseñados para escuchar música en un lugar fijo, cuentan con un cable largo, son bastante voluminosos y no se doblan ni cuentan con un estuche para transportarlos. Si deseas utilizarlos en el transporte público, mientras caminas o peor, en el gimnasio o en bici, no son el producto para ti.Estética.Son negro con dorado, bastante llamativos. No me encanta la combinación de colores, de ser completamente negros me gustarÃan mucho más, aunque qué se le va a hacer, si comprara audÃfonos por estética hubiese comprado otra marca.Conclusión.No he probado mejores audÃfonos que me brinden el sonido (plano) y calidad que estos AKG. Me gusta como suenan, los puedo usar por periodos prolongados de tiempo sin que me lastimen y en fin, los pros sobrepasan a los contras por mucho. Si deseas adentrarte en el mundo de los audÃfonos “para audiófilos” me parece una buena entrada de bajo costo y buena calidad. Si quieres algo más “divertido” y no tan plano, puedes encontrar otras marcas por menores y mayores precios, en gustos se rompen géneros y no todos buscan máxima fidelidad a la hora de escuchar su música. Cómpralos, no te vas a arrepentir, y si lo haces, no gastaste 5k< en un par de audÃfonos que no utilizarás.

jâavais essayé des écouteurs minuscules pour trous dâoreilles sans trop de succès mais avec ce K-240 je redécouvre lâécoute de la radio amateur.. sérieusement, jâaurais dû y penser avant puisque ça fait “TOUTEâ la différence.. avant, jâétais découragé dâécouter une discussion avec un signal/bruit S+2 (je choisissais les signaux S+4 ou mieux), maintenant jâévite que les signaux S+1 alors je gagne 3 niveaux “S” juste avec ces écouteurs qui englobent complètement mes oreilles dâadultes normaux avec de lâespace en extra..alors avant de changer de radio ou dâantenne pour mieux entendre les conversations, essayez ce genre dâécouteurs!!(ensuite vous jugerez mieux les autres changements à faire)..après un an dâécoute à me crisper le visage à tenter de suivre des discussions sur les ondes HF en croyant devoir changer de radio ou dâantenne, jâai le sentiment maintenant dâavoir une toute nouvelle radio super performante..jâentend tellement mieux avec un tas de détails, et pourtant je ne suis pas du tout sourd et ma radio a unhaut-parleur externe puisque ça apportait un plus à lâécoute.. alors pour moi, câest bien mieux dâavoir ces écouteursque de changer tout le reste..dâailleurs, ils semblent très bon pour la musique aussi.. ils sont très élégant, plus léger que je pensais,mieux construit que certains commentaires laissent croire (jâavais un doute à cause de ces commentaires) etje trouve la conception géniale, surtout pour le câble que lâon peut changer, la couleur dorée, lâaspectadaptatif (ils pivotent pour sâadapter à votre forme de tête naturellement, pas besoin de pivot) maiset câest à cause que jâai la tête rasée, ma peau a tendance à suer après un temps, je regarderai plus tardpour des coussins de velours sinon je mettrai une tuque pour les longues écoutes..jâai reçu le modèle STUDIO, pas le modèle MKII, juste pour préciser puisque la page semble mêlée et pouravoir été voir le site web, les caractéristiques sont pareils..bref, je suis fasciné par ces écouteurs maintenant et ça me permet une redécouverte des ondes HFsans avoir eu à tout changer (et être probablement encore déçu du résultat).. ma radio est uneYaesu FT-890(AT) achetée usagée qui date des années â80 juste pour info.. maintenant, jâen suis fier!!
Review-Fi –
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)[…].
