      Sound is very good. The only complaint I have is the connector to the cans is a little cumbersome. Very comfortable.

        Comments about KRK KNS 8400 Closed-Back Around-Ear Stereo Headphones:

        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.

          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.

              Comments about KRK KNS 8400 Closed-Back Around-Ear Stereo Headphones:

              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.

                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!

                Comments about KRK KNS 8400 Closed-Back Around-Ear Stereo Headphones:

                I was looking for a set of headphones for use on the road. I bought these after reading a lot of headphone reviews on recording/musicians/technical forums. I often do a lot of audio editing on my laptop on commutes to and from the studio and on trips. I was looking for something with a a flat frequency response, offered good isolation from ambient noise and also fit my laptop case. The KNS 8400s offered all of these features and more! I was even able to notice details in my mixes that I did not hear in the studio. I even did some tweaking on my mixes which when played back in the studio sounded fine. I am also a performing musician (bass player) so I needed a good set of cans that I can use for late night practicing, and these fit the bill perfectly. The cable and the removable in line attenuator feel a bit on the "lightweight" side but so far-so good. The attenuator can be removed and not used at all (I already have stored it in a safe place, and I am pretty sure that I will forget where that is, and I will not miss it-KRK could have left it off and sell the phones for a few bucks cheaper) . The cable uses a stereo mini jack on both ends and, on the headphone side, it twist locks into place-a better idea may have been to not have it lock, so that if the cord was accidently kicked, pulled, rolled over by a caster on a chair it would release and not cause potential damage (like older break away Sennheiser cables). All in all a great buy and highly recommended!!!

                  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.

It's clear and crisp and it sounds like your in a live concert. Compared to beats by dre headphones, i love this way more and you get more for the price as well.

                      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!
