What I will bring you in this review

Normally I would review both headphone separately, but being that these two models are almost identical (with a few differences), I will outline the K240 and then compare it to the K240 MK II towards the end.

Now without further ado, let’s get rolling!

AKG K240

AKG K240

AKG K240


  • Best Pice: check amazon! | check eBay!
  • Type: Semi-open
  • Fit: Circumaural (Over-ear)
  • Impedance: 55 Ohm
  • Frequency Response: 15hz to 25khz
  • Material: Plastic, Faux leather
  • Headband: Self adjusting
  • Color: Black, some Gold


What you should know about these first and foremost has to do with the ear-cups. They can become quite fatiguing, hot, and make your ears sweaty after a time. Since these cans are very light, it can be both a strength and a detriment.

For the most part they are very comfortable, but the build quality seems suspect. Being all plastic, they don’t feel particularly durable. Some have noted that they will break down over time, others have had them for years without a problem.

The original model of these was called the AKG 240 Sextett, and came out in 1975. The longevity factor in each of these models overall is quite good when it comes down to it.

Just be aware that neither the K240 or K240 MK II are actually made in Austria anymore. They are designed in Austria but made in China.

They have a good tonal balance, and a good, true sounding mid-range. The mid-bass is a bit boosted, but overall this is not a bass-heads headphone by any stretch. In fact, the sound signature is quite flat and neutral. There is a deep and clear bass response, but after 40hz it very much rolls off. It has a definite presence and realism to it, without being exaggerated. It’s a bit thin overall below 100hz.

The K240 also has a nice open sound-stage, with a good mid-range. They don’t feel overpowering even at high volumes. This is definitely a headphone to wear in an isolated room/studio space. They will leak quite a bit of sound and aren’t really suited for on the go, given that huge cable.


  • Detachable cable. The mini XLR connector feeds from out of the headphone cup, into your standard 3.5 mm, and comes with a 1/4″ adapter. A lot of people like the XLR aspect to it.
  • Replaceable components. Pretty much any piece on the AKG K240 can be replaced or modded.
  • An overall flat and neutral sound signature. Great for mixing, and excel at lower volumes.
  • Incredible treble detail, some say even better than the Q701.
  • Good for a lot of different applications and musical genres. More on that in a bit.
  • Has a nice warmth to it, with a certain “body” and fullness on acoustic guitars and vocals. A certain groove if you will.
  • A unique sound that many have come to adore. It really starts to open up after the 200 hour burn in mark.
  • Self-adjustable headband


This section is for conflicting viewpoints.

  • Some say they are comfortable, others can’t stand them. This has to do mainly with the size of the ear-cups. If you have small ears, you’re in business. For larger Ross Perot sized ears, they don’t fare as well.
  • Highs overemphasized, and a bit harsh/sibilant.

What does Sibilant mean?

  • Not loud enough and don’t do as well without an amp.


  • Manufacturing quality has suffered over time being that these are now made in China.
  • All plastic and extremely light. Some have had problems with various pieces breaking off. Overall the set feels cheaply constructed
  • The faux leather can make your ears sweaty after prolonged listening sessions.
  • There have been complaints of one ear crapping out over time.
  • No case
  • Bulky, massive cable
  • Lacking sub-bass
  • Bad customer support

Amp/DAC requirements

At 55 Ohm, you don’t really need an amp per se, but if you decide on the 240’s, one does greatly help the sound.

An overall great choice for many different entry level to mid level open back models is the Fiio E10K.

Who these headphones benefit?

As mentioned in the Pros section, the K240’s do well in a variety of different instances. I’ve seen them endorsed for:

  • Orchestral sound
  • Piano
  • Rock
  • Metal
  • Gaming
  • Mixing
  • Guitar tracking/mixing

Not as good for:

  • Rap/Hip-hop
  • EDM
  • Leisure listening


A pretty decent set of cans for mixing/reference. They do well in a lot of applications, but the build quality is very sub-par. I wouldn’t feel comfortable owning these for a long period of time. They are also known to be rather uncomfortable for small eared folk, and aren’t nearly loud enough with out an amp according to some.

Similarities & Differences




  • Sound-wise, these two headphones are pretty much identical.


There are 2 main differences to speak of here:

  • Choice of cable. The MK II comes with 2 cables, a coiled version and a straight version.
  • 2 included sets of pads. You have the choice of an extra set of regular pads and a nice comfy set of velour pads. ‘MERICA!

Final Word

I cannot really recommend either with the utmost enthusiasm however, so I won’t. I also don’t think the MK II’s are worth their increase in price just for a couple of added bonuses. Instead I am going to give you some different recommendations based on what you may or may not need in a studio headphone.

If you are looking for an open, neutral headphone that sounds and performs light years better than the K240, go with the Sennheiser HD 598. It’s just an overall amazing buy, without the build quality and comfort issues that the K240’s present. If you’re looking for the total package, the 598 is definitely not to be taken lightly. It is probably the best all around headphone in existence.


If you’re wanting to stay around the $100 range, are looking for that same neutral, studio reference quality, and don’t mind a closed back headphone, I would go with the Sony MDR V6 What you’re essentially getting is the same type of sound, but with increased durability and much better comfort overall. These things have been an industry staple for decades!


Finally, if you are looking for that hard hitting bass, and don’t mind spending the extra dough, my top recommendation for an open backed model would be the Beyerdynamic DT 990. These babies are quite impressive. They have a great sound-stage, are super comfortable, and utilize an amazing build quality (typical of Beyer products).


Well that’s about it for today my friend! I hope you’ve gained some further insight on the AKG K240 vs. K240 MK II.

Are you convinced that they aren’t worth purchasing? Let me know!

All the best and God bless,

  1. My observation is based on limited personal experience, but I have owned 2 pair of AKG K240S headphones and one pair Sennheiser HD280s. Both pair of the AKG far outlasted the HD280s. In fact neither pair have failed in over 10 years. The Sennheiser just stopped working after 5 years of use, and I am the only user and very gentle with all my equipment.

    • Ah, thanks much for the insight! I only had my 280’s for less than a year, but in my time with them they held up quite well. I have actually heard people owning them for upwards of 10 years! It’s unfortunate your pair crapped out after 5, but it goes to show that they do have a good longevity factor. As for the AKG’s, that’s pretty amazing! How did you like them sound wise?


  2. I have hardly ever seen such a helpful review.
    Pros and cons, important differences, and as you even recommended alternatives you got me hooked.
    Keep it up!


  3. I’ve owned dozens of headphones, and none have ever come near the durability of the K240s. I’m on my third year now with them. That’s three years of near daily intensive use, throwing them in backpacks, dropping them, getting the wire caught on doorknobs, wearing them in LIGHT rain – you name it, they’ve had that abuse.

    And they have never ever come anywhere close to breaking.

    All I am saying is that looks deceive. These are solid and dependable, and the build quality is in no way a drawback.

    As for the sound – well, they’re fantastic. But other people, including you, have described that better than I ever could, so I’ll leave the sound to the experts.

    BTW, I pair them with the Fiios E07K Andes Amp/DAC. That’s a wonderful combination.

    • Hey Jay!

      Glad to hear you had such a good experience build wise with them. I owned them for awhile and now I actually want them back! Lol. I didn’t have them as long as you, but they did hold up fine for me. What I was worried about was how light they were. It wasn’t the kind of light that made you feel comfortable about them. They almost felt like a toy. The sound however? Amazing like you say. I currently have the Schiit Magni/Modi stack, but I would love to try other things. The E07K has been on my radar for awhile. May have to try it out. 🙂

      I’m also curious as to which model you snagged. I had heard that some of the original models (not made in China), were extremely durable. Perhaps you got one of those? I have read a lot about the Chinese model, and the build seems to suffer over time.

      Regardless, the K240’s are still worth it in my opinion because of that open sound and phenomenal mid-range.
