Opinion on the KRK KNS 6400 and 8400?

post #1 of 9

Opinions? I am considering these very much but don't know if the 8400 is worth the extra money.

It's worth the extra money, but i've found it has a slightly different signature.

A little more bass, less forward lower mids and more upper mids.

 

When listening to music the 6400 sounds like it has more forward mids. I'm not sure how or why I get this impression.

Treble level seems about the same.

 

The 6400 I now have is definitely less bassy than my 8400.

I'd go with straight with the 8400's. If you are looking for neutrality thats your headphone. 

I tried both headphones but the 8400 sound signature is richer.

I knew I forgot something. The 6400 is definitely a bit thinner sounding to some (including me).

 

My Clip+ seems to add a bit of warmth (probably not noticeable to many!). I didn't realize this until I used my 6400 with my ODAC!

 

Sennheiser and Shure fans probably wouldn't like the KRKs..

Yep, its a matter of taste really. I've been enjoying my KRK's lately, they have more hours than the Shures.

I was actually looking at the clip + too. Would it be better for the 6400s to use a Fiio E6 straight out my phone 3.5MM, or without an amp straight out a Clip +?

I have the KNS6400. I am quite happy with them but they are very critical (and maybe clinical). Some recordings sound really good on them and the detail and bass precision is great. I have some extremely well recorded acoustic music that sounds very impressive on these with more than enough bass for me and the highs don't distort or sound shrill. The mids are most pronounced though. I have heard some really impressive bass coming from them (the first 2 albums of Massive Attack have very heavy bass if you want to try that out, but definitely also from acoustic music, double bass on certain Jazz recordings, Ron Carter to name one, some recordings done by Rudy van Gelder), but they don't do thumping bass, which I am actually glad about. I tried some headphones that had that thumping bass but I hate it myself as it is fatiguing and it swamps and muddies the mids and highs. Some movies that have a well produced soundtrack sound really good on them as well.

 

I find them to be critical because I have listened to many recordings that sound very weak or even crap. I do also use them just to listen to music for entertainment. In this case they are not the most enjoyable headphones as just because they are so critical, quite a lot of recordings simply don't hold up so well. In those cases the music can sound quite thin or simply unimpressive or even crap. Music that has been heavily compressed and/or brickwalled sounds terrible on these, they seem to like dynamics. With these phones I easily pick out brickwalled masterings and have checked these files in an audio editor where they invariably show up as waveform bricks. For me this is actually great as I use the headphones to mix audio with. If it sounds good on these I think you are are a long way towards having a good balance.

 

I guess that because the headphones were designed as (reference) monitors this is to be expected. They were not designed and tuned to make music sound nicer in a more general way, where the sound signature of the headphones sort of makes up for differences in dynamics and styles of music etc. It would be possible off course to use EQ to compensate. I have not had any luck with presets on my player (Clip Zip or Foobar2000), they sound terrible, and I haven't had the patience to create a setting I like.

 

So it may depend on what one would want to use the headphones for to appreciate them.

 

They are driven loud enough from a Clip and more powerful than from another player that I used before, which also improved the SQ quite a bit, but I haven't tried if they sound better through an amp.

I had the 6400s for about a day before returning them.  They were uncomfortable, had inferior quality pads (compared to the 8400s), and I found the sound to be quite fatiguing; not at all enjoyable.  I got the 8400s right after and they were superior in every way.  I think they are absolutely worth the extra money.

The KRK KNS-8400 is worth the extra money for music and gaming. It brings out the details with crystal clear clarity. When playing SKYRIM and FALLOUT 3 it makes the incredible audio work feel like the real thing as if am actually there among the creaking wreckage of civilization or in the crackly woods with a cold wind blowing through the trees as i hear bandits talking in the distance.
