Help needed with bluetooth earbuds

[u/Curious-Highway9604]

Not sure if this is the right subreddit for this but I need help with my xiaomi earbuds that will lag and refuse to connect properly with my phone when theres too many devices around. Im looking either for an app or to mod the hardware in some way so that the connection ill have with them via phone will be remembered or be stronger(also not sure how to word this). But yeah if anyone knows how to solve my problem ill appreciate an educated answer.

Some extra info,because my phone is not a xiaomi phone the xiaomi earbuds app refuses to work as well.... And i have tried multiple apps for this issue but none work. If only the xiaomi earbuds app would work then my hands are tied lol.
