Just got them, listening to Arcade Fire's The Suburbs on them as I type.
Note I haven't done any A-B testing, so those are just preliminary impressions.
Packaging: pretty good, but the hard case included with them is not the best... Flat cases like that tend to crush more easily. But I didn't buy them for the case. Ear guides are VERY nice, smaller than pictures suggested to me and I don't really feel them when I wear 'em. No shirt clip, unfortunately. The cable's not very microphonic, but I still like to hold it in place.
Build quality: nothing to complain about. Cable could be a bit less stiff, I'd rather have something like the M1 cable which I really like, but the given cable works well. Wish the strain reliefs were a bit longer, especially since the way these are worn make it possible, but I don't think there'll be any issue.
Accessories: I actually like the tips better than my fake Sony Hybrids with this pair. The quality is pretty good, and the hybrids bring down the treble a bit. With stock tips, they sound a bit more balanced to me. Hybrids could help for those who find them sibilant.
Fit: pretty good, adjustable nozzles really help. I have to play with them a bit, but they're pretty comfortable they way I've set them up so far. I still haven't made a real try with biflanges, though; I'll do that later. I don't think anybody would have a problem with fitting those. I wear them pretty shallow, and they seal well. However, I normally wear medium tips, and I have to wear the large one here. People with large ear canals will need biflanges or some aftermarket tips.
Sound: well, those are my first earphones that can be considered "high-end". They are way more detailed than the M1s I have in front of me, and they present a better balance. Actually, there's nothing in the spectrum that really stands out. At the same time, I find myself really enjoying music with them. Compared to the RE-0s I auditioned, they don't feel tinny at all, but still have a very nice treble. This is still early in my ownership of them, no burn-in at all, so take this with a grain of salt.
They are non-fatiguing, but the treble is more sparkly than I expected from descriptions; that's a good thing! I'm not that demanding on sparkles in the treble, though, so YYMV if you're a DBA-02 or RE-0 fan.
They're pretty fast, too... I tried a few tracks that are problematic with cheaper pairs (One More Time from Daft Punk, and the crazy Versailles guitar riffs), and they're fine. I don't find them dry, though... they hit a nice balance.
I'll compare them to the TD100-II tonight or tomorrow night depending on time available and give some further impressions. But from memory (yesterday's memory, so this is not a long time ago), I think they easily beat them. But then again, they're 155$... Still a very good deal, but they do cost quite a bit more money and you need the budget for it, and you need to enjoy earphones enough to make it worthwhile.
Can't compare to anything better than the RE-0, sorry. But I like those a lot more. Fit aside, they sound way way less tinny to me, without bleeding bass all over the place.
