Raspy but melodic! Realistic, in other words.

Been looking at the m50 but I really need something portable and light while commuting.


The headband doesn't fold up like the M50, so that's a bit of a negative. Otherwise, they're very similar in size to the M50, though considerably lighter.

Well, I got these today as well as the Z1000. (For some reason, the 8400 was delayed, so I have to wait a day or so for those).

 

To start off, I'll say I'm not a fan of the Z1000's tonality. It just sounds as if it's off. It's also kinda weird because the entire spectrum kinda fatigues me, and not just the treble, but generally speaking it's bright in places in weird ways. Yeah, it sounds fine still, but nowhere near what I was expecting, and nowhere near good enough for it to be worth what I paid ($325). Yes, I'm not amping it, so these are impressions from a portable source. Moving to comfort, it's not bad, but not the greatest. The earpads have very little room for your ear, so it feels very claustrophobic. Luckily, headband is pretty squishy, but I'm not sure how long I could wear these.

 

Moving on to the 6400, brings a sort of relief. Design wise, I'm liking it much better than the Z1000. Unfortunately, they don't conform to your head as good as the Z1000, so you have extra space between the adjustors and your head resulting in a more goofy look, but that's a minor nit pick. Comfort wise, I wasn't expecting much when I pulled them out, but it was a different story when I put them on. Much, much, much more comfortable than I thought. Roomy earcups, nicely designed headband (HD650 similarity) and great feel. These I could probably wear for a few hours, and probably even more so with the 8400 due to memory foam pads.

 

Alright, so on to the sound. Well, for starters, these are A LOT more likeable than the Z1000 when unamped (I don't care for amps anymore, never really found them THAT helpful). They are shockingly flat resulting in almost a thin and cold type of sound, which can take time to get used to, but it still sounds quite good as you know nothing is over done. Going from the Z1000 to these it's instantly apparent the bass tightens significantly, and the whole sound becomes more realistic and neutral. These definitely have the advantage in the midrange against the Z1000 and also soundstage, but neither is quite up to the SRH940 from what I can remember. But the 6400 does indeed sound more flat, as the SRH940's midrange boost is apparent.

 

Overall, I'm already predicting the Z1000's are heading out in a week or so, so it's mainly between the 6400 and the 8400 now. We'll see how that turns out!

I also had problems with my ZX700 sounding a bit "off" and not accurate to how some things should sound. Maybe I was just too picky. One of the few headphones where I didn't like the forward mids or it's rolled off treble. Sound clarity was a step down from the 6400 too.

 

As for the comfort of the 6400. I mentioned this in another post, but they get even comfortable within a day or two of use. Somehow it seems that they need time for the pads to adjust..however that's possible. If the pads press on your ears I just stretched mine out a tad. Wait until you try those memory foam pads! Those things are amazing when it comes to comfort. I wondered why there is so much space between the headband and your head. My idea was maybe this was needed for huge heads.

 

I'll be interested to know if your 8400's treble sounds like icicles stabbing you in the ears. Mine did until I burned them in for 3 days and it went away. I have a good feeling that there's a small chance I had a lemon or that newer pairs don't have this issue. I think you  may find the 6400 has more engaging mids than the 8400, but maybe not? Despite being a fairly neutral studio monitor I find the mids on the 6400 quite fun and engaging. Strangely they made the mids on the ZX700 bore me to death and those had forward sounding mids!

 

BTW since you'll be having both KRKs, I'd be interested in which one you think has the clearest sound. The 6400 isn't too far beind in this area compared to the 8400, but I'm going by memory. If you ever find yourself taking off the 8400's pads to try them on the 6400, see if the 8400's drivers are angled. I don't think mine were, so maybe KRK changed them to being angled?

 

If your pair sounds any different than my old one I may give them another chance. I just bought the DJ100 again and am waiting for Fedex so it'll need to wait awhile. I think overall the 8400 has more treble than I usually like. For use as a studio monitor it'd probably be better than the 6400, but 6400 seems to be just more fun to listen to.

 

It's nice to know that you say the 6400 is 2x better than the SRH-940. Just kidding. normal_smile%20.gif  For $99 I don't think maybe headphones can compete with the SRH-940. Maybe in a few areas. I wonder if there's anything the 6400 does better than the 940? Maybe not much unless it's just how flat the signature is. I wonder if the SRH-940 is much more clear and detailed than the 6400? Probably. The comfort issue of the SRH-940 has me not wanting to buy them. I bet the SRH-940 might even be good for gaming where a closed headphone is required. If it drops to $230 on a sale, maybe I'll try them sometime.

Thanks for your impressions, Katun.. keep us posted on the 6400 vs 8400 battle.. can you describe how you perceived the 6400 to sound a little more? Tonality, detail, etc. and all that?

Yeah, the Z1000 is just weird. Well, I tried to cancel them, but at least I got to try them.

 

I'm quite excited for the 8400, partly because of the memory foam pads. I'm really curious to see if I like the sound better as well. If both of them deem different enough, I may end up doing a 6400 vs 8400 comparison; we'll see. But regardless, I've noticed headroom now has both KRK headphones in stock, which is kinda surprising. This little statement they wrote is getting me excited for my 8400. Hopefully, I agree:

 

"The entry-level KNS 6400 model competes beautifully against all other cans found at that magic $99 mark and, in fact, blows most of them away in overall clarity and detail. But it’s the KNS 8400 that has us spouting words like “phenomenal punch”, “clear as a Montana sunny day” and “hell ya!” to anyone within earshot."

 

Well, to tell you the truth, I didn't even use my SRH940's that much. I used them for 50 or so hours playing BC2, just trying to burn them in, but that was a challenge due to comfort. Sound wise, yeah they were good, but I was liking my FXC51's better. So I guess you can say, if I end up listening to my 6400/8400 more, then I like them more than the SRH940. Regarding comfort, the 6400 blows the SRH940 out of the water, and I'm not even kidding. I'll have to test the 6400 with a movie so I can test it's long term comfort (where most headphones fail), but initial comfort proves it's amazing. It's funny, because the earcups are more roomy on the 6400 than on the SRH940, despite the SRH940 being like twice as big, and of a different shape.

 

From what I can remember with sound, SRH940 has definitely has more from the midrange. 2nd best I've heard actually. Bass and treble wise, I cannot really say too much there, they both sound quite similar. I'll have to use them more and test them with songs I loved using the SRH940 for, and I'll update my impressions. But for a $99 headphone vs a $300 one, differences being pretty close, I'd take the 6400 any day. Actually, I'd take it off comfort alone. The sleeker look and smaller size is a huge bonus as well.

Yeah of course. Just give me a bit more time with them, as I've only listened to a couple songs.

 

post #37 of 225

Sweet. First post......we all begin somewhere... i have been sifting through posts and forums for months now looking for headphones that would suit my personal needs. Its been the craziest rollercoaster Ive been on in a while!!!Shortlist after shortlist was created and discarded. And then I stumbled onto a comment in a thread about these "giantkillers". Thank you thank you thank you. Im ordering these on friday:-) As a musician(metal) my ears are pretty "burned in" , meaning &^*%$^. So although i am interested in Grado, I am just too sensitive to harsh highs and treble.So hearing that these are relatively bright with tight bass and nice mids with "smooth" treble, i just know they are gonna work with what i listen to. i know a lot of people wont agree but due to my ears hurting from harshness I cant wait!!! That being said, In time I will get Alessandros or Grado. I want to start recording riffs again in my room so these will def help in that respect. Cheers dudes.

post #38 of 225

alright guys, I've read the really informative posts but feel that i need further advice, so please enlighten me.

I have a situation where my walls are paper thin. Owning a pair of KRK Rokit 5's, I produce  bass heavy dance music with metal esque (not as harsh as full on metal but definitely metallic) Break beats. Hence the reason I need a pair of headphones for late night mixing/arranging sessions.  I produce certain tracks with acoustic/ambient elements but my tracks generally consist of thrashing metallic breaks and are bass heavy creatures designed to be belted out on mono club systems. 

I am torn between the krk 8400 (which I haven't heard) and the senneheisser hd 25 closed backs; which were satisfactory to my ears. Does anyone have a particular recommendation between the two? Or even another recommendation for a pair (as long as the price doesn't exceed that of the senneheisser hd 25)?

Cheers

post #39 of 225

 

just to reconfirm that i am looking for headphones that will stand up to senneheisser hd 25, heard about a bass deficiency in the krk, don't know if it was by people who are using for hi fi purposes or what, please guide me in my decision of which to purchase for mainly producing aggressive dance music at night, people mentioning hd 280, dt770, krk's, Ath-m50 all for under the price of the hd 25s.

I humbly ask the more experienced listeners to give their recommendations on the most suitable pair for my needs.

thanks again

If you want bassy headphones then get the M50 or DT770. They are pretty popular for music production too.

KRK 6400 + Aggressive Dance Music = frown.gif

Too dark? Not enough treble? Bass? Not engaging enough? Congestion? I haven't heard this type of music with the 6400 much. Maybe the 8400 will be better for it?

For me the mids of them are engaging enough for me for any genre, but maybe not for others. I don't know if this is the problem though.

 

Did your 8400 come in yet?

 

 

BTW..what's with the "...." with Cantopop? I imagine someone here dislikes it. So do it, but some is OK normal_smile%20.gif

Excuse me as I may have come across wrong, but for the average joe listening to "aggressive dance" music, they won't appreciate the very "in-line" amount of bass the 6400 has. You would think someone like that would be better off with the Pro 900 or a member of the XB series or something. For me, I can listen to any kind of music and still enjoy them. I do need to listen to them more though, but I've been a bit busy. I will admit, I'm loving the detail though, possibly the most detailed phone I've ever heard.

 

Unfortunately no. I ordered 2-day shipping last Saturday, and they haven't arrived yet. They shipped Wednesday a few days ago and are scheduled for today, but UPS tracking says it's not even in the system yet. Uh oh.

 

EDIT: Just got these a few moments ago.

 

They. Are. Incredible.

Maybe we can figure out what the deal with the 8400 was. I got the 6400 cause I was scared off the 8400 by the three who got rid of them due to lack of bass. Look forward to the comparisons, tdockweiler, Katun between the two at the same time. Not sure if we can figure out how to make sure we get good 8400's. Wouldn't want a sub-par pair but the real upgrade to the 6400 which I have nothing but good things to say about.

 

A couple questions I'm interested in(no rush, of course) is the difference in detail level, extension improvements on each end, and bass speed between the two phones.

 

Thanks in advance guys!
