BXIII is supposed to come out end of this year but they are holding off for the right release date. They told me the flagship may be released early this year but one year has passed and they still don't know how manufacture it, it may take another year or never get released. I found burn-in on my buds, tm5, ok2, m2c all has the same effect:
70h, show full potential
300h, develop a smooth fluid like sound, very pleasant but somewhat sticky
550h, dynamics show up and that's when you can begin to appreciate sound stage and layering, individual instrument is integrated and stands alone
750h, the sound is completely integrated, soundstage maximized, more refinement, more instrument noticeable, more details, before the presentation is great but the sound is grainy
1200h, continued refinement, more instrument noticeable, more details, the sound becomes tangible
2000h, continued refinement, more instrument noticeable, more details, the sound settles with no further noticeable change
I guess people don't believe in burning in partly because they just are too lazy or they expect drastic changes over one day. Depends on how sensitive your ears are, it can be very noticeable but certainly not day and night over just one day. That's why I suggest give it try, it won't kills buds or player. I burnt my m2c, ok2 on near maximum volume on nano4, they didn't break (why should they?). Other than recharging three hours a day, my nano4 run on purely battery non-stop for two months, it didn't break. And I tested the battery life, same album, same volume, still 28 hours.
I have sent a review package with a 800h m2c included, wait see how they respond.
