The Sound and feel of these Headphones are Amazing, so comfortable. Really made well. Hear want you've been missing. As soon as you put them on, the room goes dead silent. I can see how you could wear them all day with the memory foam. Excellent 5 Stars .............

"Wonderful mids, weak bass."

Overall: 3.5 out of 5 stars
(see rating details)
Verified Purchaser zZounds has verified that this reviewer purchased this specific product from us.
I love these cans for their mids. There are on the lively side, but the placement and separation is rock solid. Wonderful for mixing voice, guitar, etc. Great transient response. These would be the perfect choice, except... the bass is weak. What can I say? After a long burn-in (150 hours), the bass is better, but still weak. On the stereo, I can simply click it up one notch, and am happy. But that's not an option when recording! Too bad. I still use these for tough set-ups where the mids need to be perfect, but I need to use another set for checking the bass... PS: They very comfortable with good isolation.

"Maximum Sound, Maximum Comfort."

Overall: 5 out of 5 stars
(see rating details)
Verified Purchaser zZounds has verified that this reviewer purchased this specific product from us.
I will not buy another set of headphones. I've got KRK monitors & now the headphones and have yet to regret the purchase. In fact, when my associates come to my studio they typically go home and sell their current monitoring setup in order to purchase KRK products. Yes, they're that good.
Sound
A flat, no nonsense, highly accurate response that has enhanced my mixdowns exponentially. That KNS 8400's have allowed me to accurately place sounds within the sonic field which has given my tracks that "full" sound they've been lacking. They're essentially KRK monitors for the ears, and that's a good thing. If you produce, you need these headphones. For the price range, they can't be touched. Make sure you give them a proper amount of burn-in (about 80 or so hours) to really enhance the fidelity.
Features
Pretty simple features. However, the selling point is the memory foam on the headband and ears. I can wear these babies for hours and not feel a bit of discomfort. And if by chance they ever wear down, I can simply by replacement cushions. How sweet is that?
Ease of Use
They're headphones. If you require explanation then perhaps you should choose another field of experience.
Quality
Great build, great feel. The cord is a tad long for my taste, but perhaps this was done in order to accommodate those who need the length to reach a vocal booth or performer. Again, the memory foam is where it's at.
Value
For the money, you simply can't afford to NOT have these headphones. And they come with a chic faux leather bag. Sweet.
Manufacturer Support
This is a KRK product and, like all their products I've purchased, I have to yet contact them with a problem.
The Wow Factor
Top notch sound response comparable to more expensive headphones and the ingenious addition of memory foam makes the sex appeal a +10.

"If you produce music, you need these headphones. Period."

Overall: 5 out of 5 stars
(see rating details)
Verified Purchaser zZounds has verified that this reviewer purchased this specific product from us.
I'm no international superstar producer, but I know enough to understand the importance of not only proper monitoring, but listening to mixes on different sources. These headphones are like another pair of monitors for my studio, and help especially when it comes to panning instruments within the stereofield accurately.
Sound
The KRK KNS 8400 headphones are the best in this price range and beyond for that matter. If you're looking for heavy bass and false stereo fields, go waste your money on some Beats By Dre. But, if you're serious about music production and are looking for an accurate, transparent flat response - do yourself a favor a pick up these headphones. Don't let the immediate "dullness" of the sound turn you off, like many pro studio headphones the KRK KNS require about 80 hours of burn-in to really unleash the potential. Regardless, they're simply the best, like all KRK products.
Features
Aside from the sound quality, the memory foam (which can be replaced) makes these headphones the most comfortable I've ever worn. You can literally wear the for hours on end and when you take them off you won't feel as though your skull has been crushed.
Ease of Use
They're headphones. If you don't know how to use them you need to find a new hobby.
Quality
Nice construction, ergonomically friendly. The cord is a a bit long for my tastes, but that is insignificant.
Value
You cannot beat the price for this type of aural quality.
Manufacturer Support
Never had to use them because there products stand the test of time. My colleagues, however, tell me they're the best in the business.
The Wow Factor
Sleek design, amazing sound, ultra comfort.
