Given that these are very recent releases, there’s probably no unofficial firmwares available yet. Plus, since earbuds don’t have a physical data transfer port, any firmware needs to be installed wirelessly (and most companies tend to lock down on this). Try look around in the XDA forums, they have that sort of stuff usually.
