haha, alright. These are very rough impressions, and likely to change. Overall, the sound quality seems to be good, but not really better than the competition it seems (unfortunately). Imma try and compare them to the Denon D600's, D5000's, and Logitech UE 6000's to give an idea of how they sound (though I recently returned the UE6000's I had cause I found them to be way too dark in passive mode).
The K267 seem like they stand right in between the Logitech UE 6000 and the Denon AH-D600 in terms of sound signature. It seems like it is less balanced than the UE6000 (in passive mode), but not nearly as dark (again, in passive mode), yet still more balanced than the D600. The mids are ok, though I think I detect a hump in the lower mids/mid-bass. Overall, the mids are better than on the D600 (that's not saying much), but less natural than the mids on the UE 6000. The treble is a step up from the D600 (again, not saying much), but it feels like there's a spike around 5-6khz, and the extension is quite lackluster.
And as for bass... well, it's easier to say what it does do well, and that is 'punchy-ness'/'slam' (though, still not quite as well as the UE 6000 in active mode). Also, it seems to start rolling off at around 40hz (as opposed to the D600 and D5000's 30-25hz), and it drops sharply after 25hz. So right now, without burn-in, you pretty much can't hear any rumble at all below 20hz (for comparison, both Denons rumble down to 1-5hz), and this is on the highest bass setting ('Stage'). I got these primarily to compare the bass on them with the Denons, but so far it's looking disappointing. The D600's bass seems to have better speed, texture, clarity, and even more quantity than the K267's at this point. And for reference, I find that the D600's bass bests the D5000's in those areas as well, making the D600 some of the best bass headphones I've found so far.
In terms of soundstage, the K267 has a bigger soundstage than the UE6000, but it's not as good as the D600's, and none of those are as good as the D5000's. The imaging is the weakest of the UE6000 and both Denons though.
So yeah, the first impressions aren't very pretty, but Imma keep burning them in for at least a full day before continuing to bash them any further.
