I observed a little different....
0-5 hours....dumb phase....it sounded harsh, thin, cold
5+ hours, I heard the bass improved after every hour, like more power, more depth, more decay......
25+ hours, I heard mids opened up some air, vocal do the same, and become thicker
50+ hours, the bass is no longer changing, but mids, vocals, highs, soundstage.....these three takes turns and shine
100+ hours, the vocal became clearer, more details and space.....even had some sibilances...
125+ hours, the sibilance is gone, lower-high shown fuller body, and soundstage start getting larger
175+ hours, the soundstage has even more depth, width, and 3D images is starting to show better
200 hours.....stablelized ....no changes so far at 250 hours....
I had been listening to it...like I said, new IEMS or DAPs....to observe the changes through burn in is a privillage
The biggest downer for me was 25-50 hours. The sense of timing of various frequencies were not "on time/on beat".
Just to make sure maybe you should purchase another ZX2 and listen through the break in again
