Our take on the AKG K240 Studio

AKG designed the K240 Studio headphones for recording musicians and engineers. Their semi-open design allows high frequencies to shimmer with just enough airiness while maintaining powerful bass response. It also keeps midrange response natural, so guitars and vocals sound like they're supposed to sound.

A compromise between closed and open headphones

AKG K240 Studio

Practically the industry standard, the AKG K240 headphones provide the natural sound that's ideal for studio recording.

AKG designed the K240 Studio headphones for recording musicians and engineers. Their semi-open design allows high frequencies to shimmer with just enough airiness while maintaining powerful bass response. It also keeps midrange response natural, so guitars and vocals sound like they're supposed to sound.

Found in many pro studios, these cans are a no-brainer choice for outfitting your project studio or setting up a small home-recording rig for your computer.

Clean sound for the studio

AKG's patented Varimotion drivers deliver clear sound with extended dynamic range — that's useful during mixing, so you can accurately hear which frequencies or instruments need boosting or taming. Comfy earpads and a self-adjusting headband ensure you can keep at the mixing process until you're satisfied — not just until you're tired of wearing headphones.

An extra-long detachable cable gives you freedom to move, while 1/4" and 1/8" plug options allow you to connect to pro and consumer gear — from mixing boards and interfaces to smartphones and stereos.

Awesome Sound & Comfort

Crutchfield Customer Review (What's this?)

You can't go wrong purchasing these headphones. I love the retro look but more importantly they sound great. By that I mean they reproduce sound accurately and do not overemphasize bass like some headphones do. I have owned a pair for over a year and use them at work pretty much every day. They're comfortable and apply just the right amount of pressure around your ears. I can wear them for hours and they do not get annoying. Another nice touch is that replacement parts are available such as the cord and ear pads. I just bought these for my wife and she's very pleased with them. The AKG K240's are a great value. You won't be disappointed.

Pros: Great sound Comfortable Replacement parts available Long cord 1/4" adapter included Gold plated terminals Retro look

Cons: None

Crutchfield customer from Elmhurst, NY on 9/11/2017

Crutchfield Customer Review (What's this?)

These headphones were used by our quality control audio technicians 6 days a week, round the clock, at the major cable station where I worked for years. They stand up well for a long time before they start to fail from so many folks utilizing them. This condition will not be an issue for home use and I expect my personal headset to last a long time. The sound quality is excellent and the comfort level is high. You will forget that they are on your head!

Pros: build quality, comfort and sound reproduction

Cons: none

Best ever




StudioM from California on 6/15/2015

I purchased the K240 to take some of the workload off of my old K280 Studio Monitors(that I've happily owned/used for a long long time). Well, the vacation for my K280 didn't last too long as the K240 within the first year started dropping the left channel. I could wriggle a certain portion of the cable and the audio would come back, but it was just a chain reaction of failures after that -1.Right side plastic housing fell apart 2. Left side housing shattered as I was packing it for warranty repair?!? Well I finally had it and invoked the two year factory warranty and I gotta say, AKG took care of me. I shipped it to them and they rebuilt humpty dumpty to like new condition, sadly I rarely use it since I got back due to its' past history. Sound quality, I love the neutral nature of my older K280 and was hoping the K240 would be the same, they are unfortunately not the same animal and the K240 tends to be very bassy. So if you love Bass you'll love the K240. The cable length is around 6'(or so) ,very adequate. Fit, finish and styling is very nice and quite similar to my older K280, I've always liked the Black and Gold scheme of the K240. Depending on how big your ears are this is either going to be an on your ear or around the ear headphone, I found the covered foam ear pads to be very comfortable for long listening and easy to clean. The headband automatically adjusts. The headphone cable is designed to be easily removed and replaced by the user if and when that time comes.

Pros: Looks as good as the classic AKG's. User replaceable audio cable. Standard Mini and Large plug options. Around ear headphones. Self adjusting headbands. If you love bass, these headphones are for you. Quick no hassle factory warranty resolution with my claim.

Cons: AKG is one of my favorite headphone makers but unfortunately the quality of the material(s) used in assembling my K240 really let them down. Left channel died within a year(troubleshot to bad audio cable), plastic voice coil pieces started falling apart on both sides. And I babied these headphones! Very bassy.

Cons: None

Pros: Excellent value

Cons: None

Nice, but not exceptional

BDunham from Upland, CA on 4/24/2014

Crutchfield Customer Review (What's this?)

The look nice, the cord has a dual 3.5mm/.250" jack with a nice gold-plated threaded adapter (best setup I've seen yet for this) and a mini-XLR on the left can only. Comfortable, even on my big head. They don't quite look "pro"--maybe low-end pro. Sound is good, even, possibly a little bass-shy, but warm, even, not boomy. You will hear everything there is in a recording, the only issue is whether you hear it properly balanced. I used boost at 31.5/60/1000 and 8000 hz, cut at 125 and 2000 and I think it was better. If I listen on something where this is not possible, they still sound pretty good. It is difficult to drive them to a loud level (they are 55 ohms and apparently not that efficient), my Zenbook with Bang&Olufsen ICE amps and my Marantz 7008 are able to drive them OK, everything else comes up a bit short for full volume. Overall decent headphones, well worth the money. Keep in mind these are open-back, so they don't insulate sound in either direction. They sound more like closed phones, unlike some open sets that really feel "open". This is because the are truly over-the-ear an have a big pad that seals pretty close at your skull.

Pros: Good, even, complete sound at very good price.

Cons: Audiophile Grade "B" at best, appear to be made OK, but not exceptionally well.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

I am a recording engineer with more than 30 years of experience. These are the best headphones for recording and mixing in the studio. [ DAVID PEREZ  Aug 01, 2018 ]
Because of the good reviews. [ Ronald Anthony  Jun 28, 2018 ]
I bought a pair of these a few years ago and thoroughly enjoy them. They sound great. I often listen to them at work which helps block out the background noise and I can focus better. They can be worn for hours and not feel uncomfortable like others. My wife's old pair of Koss headphones broke so I said I know exactly what you need and purchased these for her. These are by far one of the best bang for the buck on the market today and you can even purchase replacement cords and ear pads. [ T-Rev  Apr 24, 2018 ]
The description sounded like what I was looking for. [ Jimmy  Mar 12, 2018 ]
Experience in the recording industry [ Kevin  Dec 22, 2017 ]
As a Crutchfield employee I had hands on experience with them; and let me say that for how much they cost, it is amazing on how well they preform. I would recommend them to anybody, and they are very great for mixing. [ JESSE I  Dec 21, 2017 ]
Seemed to be best balance of cost and capability in the price range I was seeking. [ Christopher  Dec 12, 2016 ]
My son asked for them for Christmas. [ Bowlerman  Dec 10, 2016 ]
During my 15 years of studio audio engineering, these have always been my favorite headphones---comfortable and lighter than expected; excellent frequency range; effortless and springy dynamic range without strain; very durable. Give your 240 designers a raise! [ PAUL  May 11, 2016 ]
price [ James  Mar 19, 2016 ]

1 question already asked

I don't see any volume controls on the headphones themselves. I control the volume by plugging the headphones into my receiver and then increase or decrease the volume with the volume knob on the receiver. [ GARY  May 29, 2018 ]
No, the AKG K240 headphones do not have an inline volume control, The volume is controlled by the device they're plugged into. [ T-Rev  May 29, 2018 ]
No, these are not powered or controlled by anything other than the device you plug them into. Hope this helps! [ carlos  May 29, 2018 ]
