The KNS8400 feel very good - sturdy and light, with the right amount of adjustability and headsqueeze - and offer a fair amount of isolation for a studio (I haven't used them enough in noisier environments, but they completely eliminate CPU whir and the sound of family upstairs). In addition to a nice fit, these cans feel pretty tough, and might last forever. For the bits that need changing because they get intimate with your sweaty head, like ear cups and arch pads, replacement parts are available, including various lengths of cord, which have a clever locking plug at the headphone end. The in-line volume control is, likewise, removable and replaceable Now, for the audio quality: I believe the KNS8400 are best suited to mastering and monitoring. They have excellent clarity and imaging, but a weak low end (even though the design notes in the manual indicate an "exrended low frequency definition"), so you may be disappointed if you are using them for listening alone. Turning up the bass on your source device does very little. This may be due to the 40mm drivers, but compared with Sony's MDR-V600 (also 40mm) they were still weak. Bigger, and, admittedly, more expensive, headphones like the BD DT770 or the Sony MDR-7509HD give a much richer listen. That being said, I am still very pleased with these KRKs because skull-fogging bass is not what I need for mixing and mastering, detail and flatness and comfort are.

I am going to keep it because I can use an extra headphone.
I am very much like others engineers looking for new age/technology headphone or monitors to see what benefits can bringing to the better mix. I found that 8400 is way less then I expected in terms of quality of the sound.
I found that it is not usable for Mix. It may help to get instrument level, but not to eq for the tone.
It is average.

        None of my other headphones can compare with these, and I have have about seven different ones. Most are not comfortable, I am so happy with them, that I take them off if I feel I'm going to sweat, because I want to have them for a long time.

        Comments about KRK KNS-8400 Studio Headphones:

        These things are really just super high quality speakers you put on your ears. They are incredibly comfortable, and I have noticed things in songs that I had never heard before, and levels peaking that mixing engineers apparently missed. These are the most amazing pair of headphones I have ever had the pleasure to listen to.

          Comments about KRK KNS-8400 Studio Headphones:

          These are the first set of studio headphones i have ever bought, but although i think they are pretty solid headphones i have to admit, i am struggling to adjust to them.
          I have only ever used krk monitors, but due to lack of use (becoming a dad) i sold them, and thought that a decent pair of headphones would suffice for the odd times i do a bit of writing & recording, so krk was the obvious choice.

          Although i have picked up again with it all :-/

          I have to say, these are super comfy, after a few minutes you feel like you don't even have them on!
          The overall sound is genuinely impressive, i can pick out every fine little detail (and being the geek i am, i like to add lots of faint little details in the background) so for that, these are perfect.

          The one downside is bass. I am a real stickler for it, and spend a lot of time on bass lines. But going from a pair of 8'' woofers to these is a little underwhelming (which is to be expected) but i am just really struggling to adjust.
          Listening back to basslines i have made with monitors through the headphones, sometimes almost sound non-existant, especially in a full mix, but i know there is a super solid bass line there. Maybe in time i will learn how sounds translate from headphones to real world.
          Hope this doesn't come across as a bad review as the phones are far from bad, just tried to be honest.

            I've mixed and mastered tracks with more than 5 different headphones and these are hands down the best. In my personal opinion, these are one of the best headphones for mixing music in it's price range.

              These KRK KNS-8400 headphones are the most comfortable headphones i've ever owned. They also sound amazing. I really like the way the cord is detachable. This means that the cord can easily be replaced if it gets damaged. I have only had these for a couple of weeks - so i can't speak for longevity - but they seem very well made.

                In general they sound awesome; really clear and isolated. They sound as loud as it has to be. They seem poor designed although I'm hoping KRK wanted to make them light but durable. Before buying them I saw some reviews about people working with them 7 or 8 hours without getting exhausted but it does not apply to me since after a few hours (2 or 3) editing I definitely have to take them off for about 20 minutes.

                I own an AKG, Bose & a few Audio Technica's, but these are my favorite!! They go everywhere with me. I'm going to get the coiled cable for when I'm on a plane. I love how solidly built these 'phones are & how easy it is to change the pieces if needed. The sound is great just enough bottom without enhancing & you hear things in your mix that were colored over with other headphones. If you are deciding on the 6400's dont!! Saveup & get these for $50 more!! One major reason is the ear piece material difference between the two. Check it out for yourself. The 8400 is the way to go..

                Simply Amazing

                By Luke Biever

                from North Las Vegas, NV

                Comments about KRK KNS-8400 Studio Headphones:

                If you want headphones for listening purposes only, that have a low end for all the bassheads, these probably aren't for you. However, if you're an artist that is in the studio a lot and need to 'know' your headphones, or if you're an audio engineer, look no further. This pair is simply astounding. KRK didn't crank the bass way up and add any flair to the sound. What you hear is exactly what is being put through the headphones. I'm in the studio with my band recording bass and vocals for a post-hardcore/metalcore band, and I couldn't be happier. The Ear and Head pads are all replaceable and made from memory foam! I can keep them on for hours during long vocal sessions and not feel an ounce of uncomfort. The oxygen free cable has gold plated tips, and is removable. The In-Line volume adjustment is VERY nice while recording, due to the fact that it is nice not to have to stop a track to adjust the volume. A really nice innovation KRK put into these, is that the headband is made from a somewhat flexible material so that it will stay to form perfectly, but won't be broken in an easy way, if it was stepped on accidentally, or twisted the wrong way while traveling. All in all, very nice. Unless, again, that you need a severe low-end drop.
