I do not have the battery issues mine both stay within a few percent of each other mostly 1% and die within 1-5min max of each other..
I did update to this FW out the box when the earbuds were new (Nov 2024) so it is the only one I have used but I did get occasional AMB Sound in left earbud when ANC was enabled (reported by others) then eventually it was every time I used ANC so making ANC useless until right now (as of typing this) I have for the first time in months gotten ANC in both ears and it is as good as my Bose and other earbuds.
