The KRK KNS 8400 is a pair of stereo headphones that provide professional-quality audio in a compact and stylish design. Created to deliver the clarity of KRK studio monitors, the headphones have 40mm neodymium drivers to produce accurate, natural audio with a frequency response of 5 Hz to 23 kHz, as well as a wide dynamic range with low distortion. The headphones have an extended low-frequency response to ensure that your bass is accurately reproduced, while a transparent high-frequency reproduction results in accurate imaging.

Thick around-ear cushions are filled with special acoustic memory foam which offers excellent audio reproduction as well as up to 30 dB of noise isolation. They're also comfortable. The headband pads and ear cushions are easily replaceable.

The single-sided cable is made from oxygen-free copper to provide a high-quality signal path. It provides plenty of slack and is detachable for easy replacement. A detachable, inline volume control allows you to make quick adjustments to the listening level. The gold-plated 3.5mm stereo mini plug offers strain relief to ensure you won't cause the cable undue stress. The headphones come with a screw-on 1/4" adapter to provide wide compatibility with a variety of audio devices. The headphones have a foldable design and include a soft carrying case for convenient storage and travel.

    KRK KNS-8400 reviews

    KNS 8400 Closed-Back Stereo Headphones is rated 4.8 out of 5 by 25.
    Rated 5 out of 5 by from Everything I Wanted I produce electronic music using Ableton and was looking for a good set of Headphones to use throughout the entire process of producing, mixing, and mastering. These things sound amazing, are built well, and are all around comfortable. Which is everything I could have asked for. The cables disconnect from the Headphones, and they fold flat for easy storage and portability. They also run at low enough ohms to be used by an portable media device are perfectly acceptable levels.There is nothing I don't love about these headphones. And for $ they were a steal!

    Rated 5 out of 5 by from MUST HAVE GADGET I have bought this just because i have a studio in my basement, I have done some sound proofing but still wasn't satisfied, on spending more towards sound proofing material, I decided to go for the KRK studio monitoring headphones so that I could do my work more comfortably without disturbing the neighborhood, the best thing is that I do not get any complains about being loud any more, I have multiple choice of monitors to select from as i use a VRM box with this and both of them make a great combo, this is very user friendly, doesn't give you hard time putting on your ears for long, and last but the best, the sound quality you get is just amazing, 100% recommended to all the people who are quality conscious.

    Rated 5 out of 5 by from Very Reccomendable I am extremely satisfied with the balance of these headphones. I write a lot of music, and I find these as a good substitute when I cannot use powered monitors. I am very pleased with the sound representation, though some research will show these do have some emphasis on bass, which I'd think is not an issue to most considering the average user does not want to invest in an expensive signal amplifier that would be necessary to represent the bass if they did make these totally flat. Short version, very happy with the product.

    Rated 5 out of 5 by from Wonderful - very happy I use these when editing video and can't monitor in the room. I have been very happy with the sound quality - better than the Sony cans I was using.Sound is clean with good highs and mids. Bass isn't over the top and seems to deliver a true representation.As a bonus, when traveling, they twist to fold flat into the provided bag. The sound delivered while on a plane is not the same as noise cancelling headphones (which I don't like for studio work), but I can clearly hear my iPad and iPod audio. Way better than any earbuds can deliver. (Like I said, this is a bonus and not my key purchasing decision.)Also super comfortable. I can wear them for hours and not end up with sore ears.

    Rated 5 out of 5 by from Perfect Monitoring Headphones! I've tried countless models of headphones over the years, and spent a considerable amount of time trying to find the best headphones for monitoring and mixing available. The KRKs give the clearest, most accurate reference I've ever heard, revealing even the most subtle details that are normally lost in other headphones. I have a project studio at home in a less-than-ideal room, and these headphones have made mixing a pleasure!

    Rated 5 out of 5 by from Very happy! Awesome cans! I am a videographer, editor, and music producer as well as a huge music listener. These headphones are fantastic. I have been using KRK products for the past 5 years and have always felt that their products produce very accurate representations of the program material. That being said, these headphones are no exception. First off, they are very comfortable. Before I even took the cable out of the packaging I wore the headphones for about 5 minutes because they were just so comfortable. The memory foam ear pads and head pad make for a custom type fit and do not create any pressure points around the ears or on the head. The headband seems to have just the right amount of pressure and the adjustable sliders stay where you put them. The overall build quality of these headphone (as with an KRK product) is very good. The plastic is a matte finish which resists fingerprints and wipes downs easily with the included microfiber cloth. All of the components seem to be manufactured well and do NOT have any plasticy smells (like some headphones do when first opened). Now, to the sound quality: THESE HEADPHONES WILL REQUIRE A BURN-IN PERIOD! Don't get me wrong, these cans sound fantastically crisp and detailed straight out of the box, but they will only get better with time. I actually felt that right away, the high end of spectrum was a little shrill and fatiguing. After about 12 hours of listening, that has lessened and the top end has smoothed out, but retains its detailed, transparent sound. After about 24 hours of listening and burn-in, the low-end has started to fill out and the high-end has reached a much more listenable quality. I expect that after about 75 hours of listening and burn-in that these headphones will sound amazing! Another thing to note is that these headphones give the impression of a large space between the ear and the driver. It doesn't sound like someone taped monitors to your head, it sounds as though you are sitting in a professionally treated studio with high-end KRK monitors 8 feet in front of you. If you like a lot of low-end oomph in your music, look somewhere else. These headphones have a very flat and accurate frequency response. However, do not be mistaken, these cans will reach the lowest of low frequencies. I have several tracks that feature 20 and 30hz rumbles and these headphones were able to replicate them both flawlessly without any distortion. Overall, these headphones have a very accurate, clear, transparent sound. In fact, these are some of the most detailed headphones I have ever listened to. With these headphones I was able to hear the sound of a guitarists pick hitting the string before actually playing the note. Incredible! That detail, extended frequency response, flat and accurate response, and musical tone combine to make these headphones a great choice for audio production, video production, and any application where accuracy is key.

    Rated 4 out of 5 by from Great heaphones, Great supplier Bought these based on recommendation from RecordingRevolution.com. They sound great. SUPER comfortable. B&H got them to me very quickly. Lowest price on the 'net. Can't beat it. Also, now I see why people are saying, I wish it came with a shorter cable. The cable has a 1/8 headphone connector (with 1/4 adapter) on one side - BUT the end that connects to the headphone is a smaller connector, and has a little locking mechanism. The manual calls it a sub-mini connector. So you can't just use shorter 1/8 to 1/8 cable. Otherwise, I love 'em. I'd buy it again.

    Rated 4 out of 5 by from Worth the money, but doesn't look good Very good clarity. Beautiful treble and balanced mids. Vocals and drums sound really good. Bass a little bit recessed, maybe just not enhanced. Great headphones for the price.
