    Great headphones, very clear and flat response. Mostly comfortable but pinch my head...
    4 Stars
    Great headphones, very clear and flat response. Mostly comfortable but pinch my head...
    I've had these headphones for a couple months now and overall I am very happy with them. They are super clear, so you will hear every little noise picked up in the recording. Chair creeks, fingers brushing on the body of a guitar/banjo, lip smacks, minor clipping, if it's on the recording you will hear it with these. I don't find them overly bright for most music, however if you are listening to something that's mixed a little harsh, it will sound harsh on these. I've found a few albums that I can't listen to on them, but I don't really blame the headphones, I blame that mix. These are not bass heavy headphones (as studio phones they shouldn't be!), but they do extend very low, with smooth bass. Sometimes it's like you can hear the air rushing past the mic on a kick drum. It's quite nice. Every once in a while I'll add a slight bass boost for certain albums, but overall I appreciate how flat the frequency response is high to low.Given the flat response, good mixes will sound amazing on the 8400s, and bad mixes will sound bad. These may not be the best every day listening headphones if you don't want that flat studio sound. However, I DO use them almost daily and really enjoy them because of what they are. I frequently hear new details in music I've not heard before on other headphones.The KNS8400s are easy to drive headphones and don't require a headphone amp. They sound a hair better with an amp, but probably because of higher quality components than a typical mp3 player or laptop, not because they need a lot of power. I've used them on a few different headphone amps (including a tube amp) and they sound great on anything. For casual listening, I don't bother hooking them up to a headphone amp.They are pretty light headphones, but feel solid. They use quality plastic and pads. The detachable cable is great, except that the jack on the headphone is unique, so you probably can't find a usable generic cable. The 8.2 foot straight cable is excessive when listening at a desk, but awesome when recording or moving around the room.My only complaint is comfort... The headband uses 2 small pads, and the gap between them seems to be just small enough that it somehow pinches the top of my head something fierce. I end up moving them around a lot to find a spot that doesn't pinch. Maybe i have a weird shaped head. They don't clamp too tight, are light, and the ear pads are very nice. If it wasn't for the pinching, they'd be amazingly comfortable.COMFORT UPDATE 6/8/2013 - DIY HEADBAND PADI saw others recommend trying the KNS6400 headband pad to try to resolve the discomfort/pinching with the headband pad so I ordered one to try it. It did help a little bit, but not completely, so I ended up making my own pad. See the picture I uploaded of my DIY pad compared to the stock pad. All I did was cut a thin strip of plastic the same size as the stock band to use as the base. I used the plastic from a small notebook cover, but anything thin and flexible will do. I then had my crafty wife sew a tube of fabric with a block of foam in it slightly thinner than than the plastic piece. Then I just glued it to the plastic base. The fabric I used won't last forever, but for now it's sturdy and makes these phones EXTREMELY comfortable now. It doesn't even look bad! I'll probably look for some nicer material/leatherette and make a more permanent one at some point, but for now this works perfectly. If you are having trouble with the stock pad hurting your head, try making your own, it was very easy since it just snaps into place. KRK should just made a pad like this as an option.I really love these headphones now.
