So I have a pair of 8400s and I love the fit/ambient isolation/inline fader, but the sound...not so much. I find the upper mids and mid highs abrasive. I'm no basshead, I was using AKG 271 or 171 before this, and both those are known for their "lean" bass, but these krks seem to lack bass even more.
I've never done burn in, but I figure it is worth a try to make these listenable. I usually listen to my music at a very modest level, usually just the first notch on ipod touch level, or 2% on my laptop, but I assume this will never burn the drivers in.
I left the headphones going overnight with my laptop volume at 40%. At about a meter away from the phones I could hear the highhats, and the 303, snare etc. I tested to see how loud this is on an ipod touch's volume at it is about 80-90% that I get the same effect.
In the morning, I am not sure I notice a significant difference. There may be more low end prominent, but the upper mids/highs are still just as abrasive if not more.
Now I'm concerned that I may have even damaged the drivers, or are they just not burned in correctly yet? Would you expect these headphones to be damaged by an ipod touch ran at 100%? I would think they should be ok with that, and it was not even 100% more like 85%. These headphones should handle that sort of volume correct? Don't people use them in amps that go even louder than an ipod touch goes?
Thanks for your insight.
