    "Clean, detailed and relatively balanced headphone with one major flaw for me personally."
    Pros - Beautiful mids, instrument separation, detail retreival, non-fatiguing, light weight
    Cons - Positional accuracy, small earpads. slight lack of punchiness (though this does make them an easy listen)
    Introduction
    I have owned these headphones for four years now. These were my first decent pair that I researched before buying. Before this I had just bought inexpensive headphones that happened to be in the shop at the time or used ones that were bundled with something. For me, the £80 (approximately) that I paid for them was a huge leap and they were basically my introduction to this hobby. As such, it pains me to give them three and a half stars as I am fond of them, however they have a flaw that not all people will necessarily encounter but it detracts from them significantly for me.
     
    Notes
    As this headphone has been around for some time, there is no shortage of photographs and descriptions of what is included, so I have forgone that part of the review. I will say that despite the plastic build mentioned by others, I have had no issues with durability. My original earpads are also in good condition despite many hours of use contrary to a couple of complaints I have found elsewhere on the internet about the pads cracking and the foam breaking apart. YMMV in this regard.
     
    I have spent the majority of my time using the vinyl pads as de-fluffing the velour pads became tiresome. With this particular headphone, I personally found the sound differences from pad to pad to be relatively minor unlike with a closed back headset which I own where the sound changes completely between pads.
     
    I purchased these headphones as a general purpose headphone. My hearing is quite sensitive, so the majority of my listening has been done at what many consider to be low volume. I have used them for music listening, movies, gaming and with guitar multi-effects units for silent practice. As far as sources go, I have used them in conjunction mostly with my PC soundcard which is a Sound Blaster Omni 5.1 surround (USB). I have also used them with a Mixamp Pro Gen 2, a Fiio X1, (briefly with) a Little Dot Mkiii (I'm currently awaiting its return) and my Galaxy S4. I feel the Galaxy S4 and perhaps even the X1 wasn't bringing out the best they have to offer. Despite their low impedance I found that they required only very slightly lower volume settings than the HD600s for the same perceived volume. As they are generally described as a neutral sounding headphone I will compare aspects of them to the Sennheiser HD600 as this seems to be the headphone most people use as a reference for neutral (with a hint of warmth).
     
    Review
    The first thing that struck me when I first used these was how pristine the sound was in comparison to a budget headset I had been using. At the time I was playing Killzone 3 and was in an area where it was snowing. I remember hearing the crunch of snow underneath my character's feet and how lifelike it sounded. I then switched back to the headset and comparatively it sounded as if it was being muffled under a pillow. I then decided to listen to some music.
     
    Despite the huge improvement in clarity compared to what I was used to, they never sound harsh or sibilant. They will however expose a poor recording. They are brutally honest and will not sugar coat a recording unlike the HD 600s which are quite forgiving. I would definitely say they sound more like an open headphone despite their semi-open categorisation. Overall I would say it has a leaner sound in comparison to the HD 600s which is more full bodied, but I certainly wouldn't call them bright.
     
    No one frequency band interferes with another and it is easy to follow individual istruments. The bass is taut and detailed, though slightly aloof. The HD 600s by comparison immerse you in its bass whereas you never feel like you are being engulfed in the same way with the K240 MKiis. While they can reproduce some sub bass, they don't seem to dig quite as deep as the HD600s. The mids are this headphone's biggest strength. Somehow they manage to be incredibly detailed and textured whilst simultaneously warm and smooth. I'm not sure how they manage to acheive this as I would have thought you'd have to trade-off warmth and smoothness for detail and texture, but apparently not. I feel that the highs may be slightly rolled off, but for me this isn't to the detriment of the headphones. There is enough up top that you don't feel it's missing but it never becomes unpleasant. This is a headphone that is very easy to listen to for hours on end. One thing that contributes to this can be viewed either as a pro or as a con. They aren't the punchiest headphone in terms of dynamics.
     
    Here is the negative part. The positioning of audio cues is completely different to any of the other heaphones I have subsequently tried. In video games for example, this manifests itself by sounds that should be coming in from 45 degrees off centre coming in from somewhere around 50-55 degrees. In music, hard panned sounds actually sound as if they are coming from slightly behind me. Music that has panning effects where a sound moves from left to right can occasionally sound as if it is passing behind my head. With certain recordings it can actually make it sound as if the centre instrument/vocal is wider than it should be. Similarly, in recordings where there is nothing dead centre but two sounds slightly left and right of centre, it can create an empty sounding spot in centre where in other headphones the left and right share the centre with just a bit of stereo separation. This makes sparse sounding recordings sound incredibly sparse. On the other hand, this does make it incredibly easy to isolate instruments and follow them individually. The one issue this does present is that music isn't as cohesive as it is on the HD600s. So it is a plus for analysing music, but detracts from musicality and identifying directional cues in video games.
     
    It took me a long time to identify what the problem is, but I think it is due to the way the headphones sit on my head in relation to my ears. Due to the small earcups, to accommodate the height of my ears I must have the tallest part of my ear dead centre (even then my ears touch top and bottom). This means that the driver sits further towards the back of my head instead of being positioned directly over my ear canal. Also, due to the lack of clamping force, I think the earcups sit in a position that don't angle the drivers towards my ear canal. Perhaps this wouldn't be an issue at higher listening volumes where more sound fills the earcups and makes the sound less directional (I'm speculating here), but for me personally it is an issue as I don't enjoy listening at high volume.
     
    I have decided to give my K240 Mkiis to my mother as she is much less critical of the problems I have with them and positioning of audio cues is not as important for her usage. I've not measured her ears but it may not even be an issue for her if the cups fit her ears better than they do mine. Despite its many strengths, since becoming aware of the problems I have with this pair of headphones they are all I notice now when using them. I would love to try another AKG headphone in future (I'm interested in the K712 Pro) based on the strengths of this one, but I would certainly need to try before I buy.
     
    I hope someone finds this review valuable.

    4.0/5,
    "Great studio headphones for performance... Good casual listening experience as well."
    Pros - Nice texture in mids to highs. Decent price. Exciting studio performance headphone.
    Cons - Weak plastic build. Plastic components in ear cups will wear out, snowballing into further damage. Extremely bright.
    I see a lot of reviews on here saying that they are "super smooth" in the mid range... Well I will tell you, the mid range is very interesting on these headphones... But it is definitely harsh. I always need to roll the volume back to accommodate this one peak in the mid range which dominates the spectrum. Don't get me wrong, they sound very exciting and fun to listen to, especially for music with reverbs. They show up due to the brightness. Bass is lacking, as is obviously inherent in using the term "bright". The best impression I can give is that they have a sort of "analog drive" to them which is very 70's sounding, and the I have a feeling that the mark 1's would have the better, more pleasing version of this. What I am saying is that in this sort of bright classic sound, an older original pair would hopefully not have the sort of sterility of a modern pair. 
     
    I believe these were originally found in studios for musicians to perform with, and that makes sense, because they are very "exciting" sounding... They make your performance sound a bit more golden. DEFINITELY not neutral, as some reviewers have been saying. Neutrality to me would mean that each instrument coming through the speakers would be indiscernible from the actual real-life instrument. A truly neutral pair of headphones would give the impression that musicians were performing in the same room as you. This is not the case with the K240's. Physically, they are very comfortable but sound-wise, they could hurt your ears easily at. They are probably some of the more fatiguing headphones out there. That being said, even after 5 years of use I am finally putting them through an intentional burn-in period of loud use in hopes of softening them up.
     
    Another consideration is their structural build... You would think that the headband would be a hollow tube with a wire through it, connecting the two earpieces... This is not the case. The headband itself acts as the bridge between speakers. The speakers are soldered to each end. At each cup, the headband splits open in sort of a "Y", which rests in a little plastic bed, and gets clamped in position between the speaker and the little round plastic piece with the logo on it. On the ends of this "Y" are the speaker connections, soldered. Don't get me wrong, I think the headband is really cool and a brilliant bit of design, if I can say that prefaced with the fact that I do not have a broad idea of what is "good" design - the headband is not actually in itself at fault. The problem is that the wire connections WILL break with use. The plastic beds on the "Y" will crack from twisting, leaving the cups to twist a little more than they should. When they bust loose like this, it leaves the extremely thin wires inside prone to constant bending and eventual snapping. I had to fix mine by taking them apart, gorilla gluing the plastic pieces back together, leaving it for 24 hours, then soldering the connections back on. It's just a design flaw which I encountered after about 5 years of ownership.
     
    Hope this serves as a cautionary tale. By all means, I encourage you to buy these headphones, because they are a lot of fun, have an interesting sound, and will give you years of enjoyment. Not to mention being a staple in recording studios. I am just saying, make sure to send your warranty card in, because with this design, it is only a matter of time before the damage I mentioned becomes present. Thanks for reading.

    5.0/5,
    "Decent detailed sound. Good value for the money."
    Pros - Details, Loud, good bass and mids
    Cons - Not suitable for mix and master
    I'm professional musician and I bought it for my home studio. I own also Sennheiser HD 449. From my perspective It might be difficult to mix and master on these AKG if you are not used to them because they are heavy on bass and middles, sound is not balanced. HD449 are more suitable for that purpose because they are more balanced. I still use AKG in the end to check if song makes even more impression in good headphones. Anyway, If buy them for listening to the music - they are the best. The sound is brilliant - good mids, punch in the bass, very clean highs.
