It should be okay, IIRC sometimes there's extra buzzing(interference)/heat/etc. though.

For TWS earbuds and Bluetooth usage, see here for more info: https://www.reddit.com/r/headphones/comments/10kai7u/should_i_keep_ear_buds_out_of_the_case_after/j5so87z/

Here's what I do with my TWS earbuds and TWS adapters (like FiiO UTWS3/5) or really Bluetooth/wireless/rechargeable/etc. stuff in general: I try to only charge it when it has no battery or will have no battery soon. And then I don't touch it at all while its charging.

Info about UTWS3/5 battery life (5-7 hours) and also TWS earbuds volume variability: https://www.reddit.com/r/headphones/comments/10yr7js/finaly_good_audio_on_the_go_utws5_and_fh5s/j803bbw/

For Bluetooth ANC headphones, those can take a while and yes, just leave them be, use a wired IEM/headphone instead or your speakers.
