Dem speakers

By Mark Hill

from Salt Lake City Utah

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.

fav headphones

By ERNEST ANDREW

from Kendall, FL

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

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.

Accurate, truthful, pure bliss...

By Tyrone Beats

from Las Vegas, Nevada

Read every review on these if you want. You will read the same negative rhetoric about bass. These are not headphones for the average consumer who wants music dressed up and sugarcoated. If that is what your looking for head to Best Buy and grab some Beats by Dre. These headphones are for serious engineers, producers, dj's, and re-mixers who need and honest genuine pair of headphones in an environment that do not allow the use of studio monitors. I spent eight hours "Burning them in." I mixed down a few Rap tracks and a couple of Pop, and Techno. Played them back in the car, lo-fi monitors, and through my Android phone. Very impressed with the results. Keep in mind if you can't mix in the first place your finished product will still suck. "Just because you rock Jordan's don't mean you can dunk like Michael."

Excellent Alternative To Monitor's.

By Adam

from Methuen MA

Im a producer and dj.I have been a producer for almost 15 years.Working with electronic and hiphop music.These headphones are a also alternative to studio monitors because they are just that for your ears.I cant really produce where i live now for various reasons especially not having a proper sound proofed room.These are the best investment i have made.But be cautioned they need time to burn in.When u first buy them there gonna seem to sound like cheap headphones.But after about 12 hours of consistent play they sound AWESOME.I played TCM'S high roller through them while i slept for about 8 hours and then ran a frequency sweep from 20 to 3000 for about 4 hours and now they are perfect.These headphones are really top notch and i would recommend them to anyone as a studio monitor alternative.

comfort and build quality

By noah montena

from syracuse, ny

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.
