These are great headphones I've had them for 10 months and there still going strong and have been pretty durable for being made of plastic. When you first get them the highs on them can be a little piercing but after about 20 hours of burning in they sound great. some people have been complaining about the bass on these which I have something to say about, normal human hearing is between 20-20k hertz these headphones produce 5-23k hertz because of this the bass frequencies sound more natural, this makes these headphones sound more like studio monitors rather than normal headphones which tend to normally have a woofy low end to block out outside noise. this means instead of hearing a thump for the drums you can hear each drum individually and differentiate each type of cymbal on a track. also the eq on these is extremely flat which is makes them better than a lot of other headphones for mixing. Somethings these headphones have which will make them last longer than normal headphones is all the padding is replaceable and all the cords and adapters are removable and replaceable, so in like 5 years if a cord goes bad you can just replace it with a new one instead of going out and having buy new pair of headphones. all of these things make these headphones great for mixing and and in the studio but also great for casual consumer uses as well.

I have had a pair of the KRK Rockit8's for over a year now and just got these headphones about a month ago, and like their advertising, they are the same sound. I am very pleased with these, I can actually do a little mixing and beat-making with them. They are also the most comfortable closed ear headphones I've ever worn. If you have KRK monitors and love them, you will love these headphones.

I'm an owner of quite a few headphones Shure SRH750, Audio Technica ATH-M40fs, etc. Anyways, back to these headphones. First off, they are by far one of the most COMFORTABLE headphones I've EVER worn. Not only do they have EXTREMELY generous memory-foam padding on the earcups (interestingly enough, the headband cushions are not memory foam, and are actually quite hard and stiff), they are also crafted from extremely LIGHT, yet durable plastics. You can definitely tell the build quality is top notch the minute you pick these babies up hinges rotate without hesitation and effort, adjusting headband hinges are made from a combination aluminum/metal and plastic, and the plastic they use is a tough, durable, semi-rigid type.

For the sound quality, I still haven't burned them in 100%, but from what I've heard so far, the highs and mids are so CRISP and pronounced. They will allow you to hear sounds you've never heard in your music before. For the bass...these would most definitely NOT be the first pair of cans I'd recommend to a basshead friend of mine. On the other hand, for my purposes, the low register will suit perfectly. These are MONITORING headphones. Which means they don't colour any of the ranges, whether it be highs, mids, or lows. The earpads block out a fair amount of noise. Although the impedence is quite low, my PC and phone struggle to drive the headphones...something I thought was quite odd, as videos reviews of these headphones state that it is quite easy to play at a high volume level. The soundstage is small, as are most closed-back headphones...slightly above-average at best. Don't listen to the KRK videos when they say it's easy to drive, tremendous sound isolation, very wide-open soundstage; that's promotional exaggeration. Sound and instrument separation is great though.

The 8400s are actually quite small headphones. The earcups do fit my ears nicely though (and that says a lot I have Dumbo-proportioned ears), but the headphones themselves are quite small in comparison to other monitoring/DJ headphones (Sony V700s, etc.) In terms of aesthetics, they aren't flashy in the slightest. They are very modest, matte-black headphones, and are a tad similar in terms of looks and feel to a pair of Sennheiser HD 4X8/4X9 series. You're paying for the comfort and sound quality, not the looks.

These are feature-heavy headphones. The earcups rotate 90 degrees for flat storage, and one of the two earcups (right side) can be flipped 180 degrees for one-sided monitoring. Cables are detachable, and included is a volume-control section, as well as a REALLY long cable (I believe 9-10 feet long). I'd preferred to have a shorter cable be included as well for more portable use while on the run with an MP3 player or phone, as the cables used are quite uncommon and specific to KRK (i.e. 2.5mm to 3.5mm (1/8 inch), and it's a twist-n-lock system, meaning you plug the 2.5mm ended part of the cable into the headphones and twist it to lock it). It also comes with a nice leather carrying case, a 6.3mm (1/4 inch)screw-on adapter, a polishing cloth (the outside of the earcups have some metal on them), and manual.

In summary, the KRK KNS8400s are a great pair of headphones, and would definitely recommend to anyone looking for a neutral-sounding pair of headphones. I will post another review in another few weeks after some more burn-in time.

Want KRK KNS8400 Studio Headphones Discount?

First let me say that if you're in the market for headphones that make everything sound it's best, THESE ARE NOT THE HEADPHONES FOR YOU. Not that these sound bad but it seems a lot of people have missed the point of headphones such as these.

These are monitoring/reference headphones. They are designed for music production. As such, they reproduce the sound as closely to as is as possible. Therefore, if what you're listening to on them sounds bad, it's likely because the recording is bad.

As far as what they're designed for, the do a pretty good job. The detail is amazing and when adjusting levels in a mix and panning, the are surprisingly accurate. I own these as well as the shure shr840's. The highs are crip and not harsh as well. Great for those fine tuning adjustments to add that sheen without completely destroying the song which can be easy to do if you can't get your highs right. Here are a few things about the KRK's that cuased me to only give 4 stars:

1. While they are not supposed to have a huge bass response, I believe the bass is perhaps rolled off a bit too much. To the point where making critical adjustments in a mix requires a fair amount of guess work. The shures are slightly better in this regard.

2. There seems to be a boost in the lower mids, perhaps around 100khz. This gives the KRK's a more boxy sound compared to the shures and it takes some getting used to. So if you have used other cans, beware of this.

Otherwise they are light and comfortable for their class and can be worn for long periods.

I've had KRK V8's (first gen) for years now. Love them for mixing, but also just for listening to anything. Unfortunately, the sound, and feeling i get from listening to them is not portable. I've been spending stupid amounts of money on earbud head phones over the past couple of years to try to find something that could rival the feeling of listening to my monitors. Nothing really came close. I used to avoid over ear headphones, but when I learned KRK started making them, I had to try. So here goes:

These things are extremely comfortable.. I forget about them and have already worn them for a nice 10 hour session.. No problems, no fatigue, less sweat than expected.

The sound is unreal. Seriously. Uncolored and just beautiful. I have heard new things in almost every quality recording that I have listened to. Sadly, I have also heard tons of garbage in my own recordings/productions.. I guess they will only help make me better. These guys are unforgiving, but amazing.

I don't know what the other reviews are talking about when they say bass is lacking. It is there and it is actually DYNAMIC.. Listen to some cello on these guys.. It is an epic experience.

Overall, I truly love them. My quest for great headphones and sound is over. Pick these up before KRK realizes what they have here and starts charging five times the price.
