The AKG K240 MKII Professional Studio Headphones have an over-ear, semi-open design. The mid-priced cans are intended for:
“precision listening, mixing and mastering”.
The MKII is an update on the AKG K240 model. The older model is still available for approximately half the price of the new version. The original was a popular pair of studio headphones, although some users said the level of comfort was lacking. The MKII ships with an updated earpad design and offers both leatherette and velvet earpads. It also adds two detachable cables, namely a 3m straight cable and 5m coiled cable.
Quality sound and comfortable build
The AKG K240 MKII features Varimotion 30 mm XXL transducers. The semi-open design provides the comfort of open headphones with the bass response of closed designs. The headphones are fairly large but they are surprisingly light. They are well-suited to long sessions. They have a self-adjusting headband which naturally fits the contour of your head. My head is on the larger side and it fits quite well. I had a petite female vocalist use the headphones in the studio and she said that the self-adjusting design didn’t fit to her head quite as well. She did say that the headphones overall were still pretty comfortable, which makes sense because the design evenly distributes the weight on the head. The product ships with leatherette pads on the headphones, and I didn’t have any problems with these pads. The velvet earpads would absorb sweat easier if that is an issue. The changeover between the two pad types is a little fiddly but doesn’t take too long. It’s also easy to get hold of replacement earpads if they get damaged for some reason.
I use the included 5m coiled cable when working by myself at my desk. When tracking with another musician I use the 3m straight cable. The straight cable may be shorter but it’s more suited to use away from the headphone amp. The coiled cable starts producing a noticeable resistance when moved more than a meter or so from the headphone amp. The changeover between cable types is quick and easy. Both cables end in a 3.5mm gold-finish jack plug and the headphones ship with a 1/4″ screw-on adapter.
Solid construction for AKG K240 MKII headphones
The headphones are solid and made of quality materials. They aren’t completely indestructible but you’d have to mistreat them pretty badly to break them. In 18 months of use at home and in the studio I haven’t managed to damage them in any way. They are mostly suited to use at home or in the studio. They may be light but their size makes them unsuitable for portable use. The included cables are too long and heavy for portable use. They would be fine for a long car or bus trip. I wouldn’t take them on a 30 minute trip on the train to the city though.
Clear, flat response
The AKG K240 MKII headphones sound clear and well-balanced. The bass sounds full and the highs are pleasant. The mids could benefit from more detail, although I had to closely analyse the sound to pick it up. It’s not something I was unpleasantly aware of during regular playback or anything. The headphones have a fairly flat response. They are not perfectly flat but you won’t find any headphones at this price range that are. Due to the honest response, the K240s are most suited to audiophiles and people who want them for professional applications. Those who just want to jam out some tunes would probably enjoy a headphone with a more tailored response. Listening to the headphones can take some getting used to. They highlight inconsistencies in a mix very well, and all the elements of the mix are quite easy to pick apart. I find myself noticing things that I didn’t pick up on when listening to the same songs on different systems.
Well suited to the studio
I bought the K240 MKIIs with the intention to use them for tracking in the studio or as an alternate reference when mixing songs. These are the applications which the design are most suited to. The cans would be at home for use in any kind of recording, mixing and editing work. The semi-open design sits light enough on your ears so that you don’t mind using them for extended periods. They also enable your ears to breathe sufficiently so you don’t start stewing in your own juices. When used for vocal tracking the vocalists I worked with reported that the headphones were comfortable and that they could hear their parts and the music quite well. When music was not being run through the cans, the musician could hear my voice easily. The semi-open design did not produce any noticeable bleed into the mics despite having them up fairly loud. It’s worth noting that the headphones are fairly quiet compared to other headphones plugged into the same source. But hey, that’s what the volume control is for. Their slightly lower volume output has never caused a problem for me.
The AKG K240 MKII is a well-priced product which offers solid build, useful features and honest sound reproduction. For the price, you won’t get much better headphones for use for tracking, mixing and editing. They will be well-loved by audiophiles and people who need a quality yet affordable pair of headphones for the studio. They are not particularly suited for casual listening or portable use, but they are not intended for these functions.
The sound is the best I have heard for the money.
When I play my own music back, my better mixes are very clear and my weak mixes are very obvious.
Crisp and airy highs but solid bass as well!
I’ve been using this headset for about 2 years now, and i can easily say i haven’t looked or thought about a replacement.
