After 24 hrs. here is my summary: They sound superb, smooth as silk and worth way more than the asking price. The burn-in really evened them out. The transition from bass to mids is seemless on through the treble region, which is, well - smooth. They don't shout or bark at you at all. If recordings aren't the best, they will expose every flaw, they don't smooth them over. They are unforgiving in that sense, while a good recording really shines. Granted, I'm not as adept at reviewing as I've read here but suffice it to say, across-the board they are superbly musical. After spending several hours with them, I am super happy with the purchase.
It confounds me how these budget IEMs can sound so good. I took a listen to my Chus, Zeros, QKZs, KZs and a few others in my budget collection (thanks to reading about them here) and they all sound good. These are right up there at the top if not THE top in overall sound signature. My Chus were the first ones I bought and they hold there own. Switching to my higher end headphones for kicks, leaving out the listening experience difference and just focusing on tonality, I'm really amazed.
A very happy camper here...
