Listened to the whole review and am really offended! Just kidding.
I agree with most parts of it. I still think someday i'll have to have you hear my pair and see if you hear any differences. I think you will!
The 8400 is actually fuller sounding than the 6400 I think. Out of my portable player and amp it was a bit thinner sounding than it normally is.
Wonder why? I'll test it out and see if it's any less thin with the more power I gave it.
I remember playing Skyrim with it using a Turtle Beach DSS to my Micro Amp or E9 (large jack). Compared to my Q701, it at times sounded much warmer and full sounding. What the heck?!
After switching to it from my DJ100 I was just totally baffled at how much thinner and tinny sounding it was. That's not it usually sounds!!
The 8400 has actually more sub-bass than mid/upper bass I think.
If you try it with gaming, there's actually some sub-bass that is more present on these than compared to the HD-600 and Q701. Think I'm joking? Try it!
Well, my first pair had almost AD700 like bass. This pair is closer to the Q701, but with more sub-bass.
Maybe they're like my DJ100 and Q701 and sound a tad thinner when they don't have a ton of power. Who knows..
Some harsh Jpop is unbearably bad on them. This is just garbage tracks though. Doesn't make it any easier on the ears.
My favorite music for the KRK KNS-8400 is acoustic guitar music with a large soundstage or ambient electronica. I also love them for video games like Fallout 3 or Skyrim.
I'm off to test them out some more. I never realized how warm my DJ100 was until I switched to it from these
BTW if your pair has relaxed mids (not forward sounding at all) and lots of treble, it's probably like the first version I had. I don't know how the heck a headphone can have little bass, relaxed mids and too much treble. Is that even possible?!
