Regarding "driver flex" I'd think it would not be anything to worry about too much. I don't have much experience with IEMs having it, but as has been said before, the way you insert the earbud in your ear could generally remedy it. Particularly the angle of insertion and speed it is thrust into the ear canal.
I design and build speaker systems and have some knowledge of the workings of how drivers interact with the box (enclosure), baffle, port, and tuning. Ports are used to tune the driver to the best resonance of the enclosure, to get the best low-frequency response the driver is capable of. When the cone of the driver moves with electrical impulse, the air in the enclosure (and coming through the port) moves in response to the forward excursion of the cone, dampening it. It works kind of like a pendulum effect of inward/outward movement of air behind the driver/baffle. The physics and math can become complicated, as each particular driver (woofer) works best with an exact amount of air in the enclosure, and a particular diameter and length of port for the best tuning resonance. There is a phenomenon of port "chuffing" as well, where the port can create noise itself when air is moved through it.
Regarding "burn-in" I'm also a believer in a period of time where the cone and diaphragm (moving coil) of the driver loosens up a bit to work at its optimal, intended range of movement. I've heard drastic changes to speakers that I have built after this period of use (movement of cone) is conducted. I don't really think there can be an exact amount of time specified (as the excursion would be so different with the music played, etc.) though, and generally, in my experience, the most drastic changes to the sound (mostly in the LF) occur within the first few to dozen hours. I sometimes use pink or brown noise to play while conducting a "burn in" of a new speaker set, as I have settings for those built-in to some of my studio equipment. I don't really think there is any such thing as burn in with balanced armatures. But as the IT00 is only a dynamic driver, I think it could benefit. If you don't believe in "burn-in," it doesn't matter anyway, just enjoy it right out of the box, and indefinitely.
I also believe we all have a brain burn-in too, where the sound and tuning we are already accustomed to needs a period to reset itself to something new. Most people are not even used to multi-driver speakers with accurate and wide frequency response reproduction. Which is why the V-curve is a popular tuning as its "fun" and engaging and a proper mid-range seems too strong for many, just because they are not used to hearing it.
Anyway, I'm babbling because I don't have my IT00 set yet and have nothing else to contribute to the already great reviews and impressions given by the many others here. Looking forward to hearing them in a day or two!

what kind of tool you ordered ?
