Firstly, I'll say that I was looking for headphones that I can mix on so flatness and balance were the characteristics that I was looking for.

These are definitely the most comfortable headphones in this price range. Memory foam is such a pleasure for ears. You can wear them for hours forgetting they're even there. :)

Sound wise they are very well balanced. I read a lot of reviews before buying them that said they lack bass... Definitely not true! They have bass. I don' know where people got that from. Not pumped up dr. Dre bass but they have it.

To make this review more interesting for comparison, I'll add that I bought these headphones along with Beyerdynamic DT-770 Pro (80 Ohms) and Shure SRH840.

I've tested all 3 pairs for 2 weeks. Beyers were too wide for me, stage was too spacy, seemed a lot like surround sounding. With Shure's I didn't feel that they are appropriate for mixing purposes and reviews mentioning breaking of parts added to the "no" scale.

My recommendation is that you order a couple of headphones that you narrowed down and test them all like I did. Thomann's service is unbeatable - you can return the ones you don't like. ;)

I bought these to replace my ageing AKG's after reading a lot of reviews on the 8400's these seemed the perfect replacement !
I do a lot of mixing in the evening so use headphones a lot so as not to disturb next door.
They claim to be like studio monitors for your ears & I can safely say they are not wrong these sound supurb clear un-coloured sound ! The differance between the 8400's & my old AKG's is amazing you can hear everything in clear detail which is what you need when your mixing.
As for build quality again supurb very light & comfortable to wear the cables are detachable & there's the volume control which is very useful the cable length is very long.
All in all if your looking for pro headphones then you won't go wrong with these & the price is very reasonable !

KRK KNS 8400 are good and reliable headphones.
Artyom Donka, 30.08.2013
"+" High quality product, perfect details in panorama, mids, highs, comfortable and for a good price. Good acoustic insulation.
"-" Some of the guys tested these headphones and found them very hot after wearing for a some time. But I think this is a usual thing for a closed type headphones. Low end is very flat or ... I have to compare with other monitoring headphones.

Update 2021: I love these headphones and they've been serving me well for 8 years now. I got used to them in the means of comfort and frequency response curve. I love to use them for surgical jobs, because of their precision that allows me to focus on tiny details that I might miss when using speakers (i do mix and monitor with them as well). I have not been using them everyday in a busy studio, but they had their duty for these years. Well, I wish it would stay like that for a longer time, but I must inform that now I have to replace the ears and headband cushions. But 8 years guys. I could not find original replacement and also read they are at a biting price so the parcel from China is on the way and my hope they will work the same.

Conclusion:
Cushions is the only issue I had over the period of use. Connectors and wire etc - all is good. But I also used headphones with care.
Yes the bass is moderate. But it is there.

Comfort is a mystery
Neal, 05.10.2020
So these are great. Well padded, and fit tight to your ears. Good bass response and fairly flat overall.
They do great as monitors for recording, great for reference and good for mixing.
Replaceable cable is great, included length is HUGE. And there is a detachable volume control which is again great for monitoring.
Maybe it’s a bit harsh but I do find the top of my head starting to hurt long before my ears get tired. Disclaimer, I do have a big head but they are a firm fit.
