I watched many youtube videos and reviews before buying these headphones, and googled several reviews. The most accurate description I came across was simply, and I quote: 'its like wearing the KRK monitors on your ears! (soundwise of course!) I have KRK6 G1 monitors and they sound like them in all respects.

Been doing sound for many years. These are pretty accurate given they're only $99. Cant think of any othe phones that will be sonically neutral for the price. Don't expect incredible fidelity and stereo field accuracy of those that cost much more but you also won't feel like you're missing important details in a mix. They're as accurate as you can ask for - if you're mixing, that's, IMO, is the mos important component of monitor headphones.

I was really disappointed with how thin and tinny these sounded. I've been trying them in the studio for a few sessions now for tracking and everything sounds so harsh and brittle. I switched to a pair of Audio Technica ATH-M50's and found them to have vastly improved bass response and overall, more fullness and definition than the KRK's. On the plus side, they are comfortable and do isolate well, even with a loud drummer.In addition, I A/B'd them just using my ipod and an older pair of pretty inexpensive AT's that I had lying around and in that application as well, the KRK's sounded shallow, metallic and really thin.

It would be nice if the 6400s had the volume control that the 8400s include, but these headphones have exceptional fidelity. Great for the pro studio setup. These are not intended for the commercial market, but I use them as my go-to headphones for any application. Go to a Sam Ash and try these out for yourself. Exceptional clarity. Resonant bass. Mids and highs are well balanced.
I've used the same ones for many years so, I know the product and its reliability.
and, it's no surprise it was KRK. I've used KRK V6 and V4 studio monitors for several years now and absolutely LOVE them. So, when I saw they had come out with headphones I was very interested. I've been using SONY 7506/V6 headphones for twenty years and, after comparing them with several brands in the recording studio, swore I'd never use ANYTHING else. My KRK's arrived today and I was first very impressed with the build quality and great features. A detachable, replaceable cord? YES! The attached, coiled cord on the SONY's has always been a design flaw in my book. And, I don't know HOW many pairs of phones, some very expensive, I've trashed in the recording studio after a client has stepped on, and shorted/pulled out, the cable.

Next, the KRK's have replaceable ear and headband pads. Another SONY downfall. So,as great as all that is, none of it matters if they don't sound good. I pulled up the mix I'm currently working on, listened to it through the studio monitors "KRK V4's" then put on the KRK phones. VERY comfortable and great ear coverage. With my SONY's at hand, and ready to run a comparison, I hit play. The SONY's never came out of the bag. The KRK's sound EXACTLY like what I get from their studio monitors. There were none of the "well, maybe a bit odd in the mids or bass-heavy" thoughts. These things are amazing, and that's a tragic understatement. NO distortion at WAY too high volume levels, clarity to spare, and the most incredible fit/feel of any phones I've ever used. Sorry SONY. I'll always love ya but KRK just took your job. Final thought... GET THESE NOW!
Over 40yrs I have spent a fortune on Headphones with all the major brands. It has always been difficult to find a set of Headphones that Don't Leak Sound that is until I researched these beauties. Very comfortable and no sound leakage whatsoever. I can now have my music as load as I want without disturbing my family. Constantly saying we can hear them turn them down or go in another room. So just what I had searched so 40yrs for I kid you not. I've had Bose Sound Comfort 25s, Senhneisers, Sony,etc and none match the sound through this headset. You have to remember these are designed for Artists so that they can sing into the mic and not hear outside sound or leakage from the headsets to the recording mic. Thats why they are 1st class in my opinion. Another great ... MoreOver 40yrs I have spent a fortune on Headphones with all the major brands.

These are good in terms of sounds and comfort. I agree a lot of what the first reviewer said... except for the suspicious fact that he says he is an experienced (33 years) engineer yet he says he would actually throw away headphones because of bad cables! They're good for tracking and even mixing. They don't translate as well as good neirfields, but they will work, and especially if used in a rotation of monitoring sources; but that is what any good mixer would do. Present mids and nothing overhyped in the lows and highs.
as soon as I put them on awesome sound tight bass smooth midrange crisp highs. nice and lite very comfortable .had audio -technica m-40- x the krks blew them away for 100 bucks can't go wrong you will not be sorry .I am 71 years oid been a stereo man for 50 years best phones I ever had larry from south jersey
