I probably have the cheapest headphones you can find, so I don’t have any expectations.
My main 2 problems are that at 30% battery I get a quadruple Battery Low alert into an automatic shutdown. There seems to be no way to turn off the LED lights which seems to be quite a big battery drain.

If they work with a standard 3.5mm cable, using them with that would avoid all the hassle? Yes there would be a cable but it would never spam you with battery notifications as they would never run out of battery.
I don’t see any other options I am afraid, if you want to keep using those headphones.
Whilst you say you don’t have any expectations, I think you may have set your expectations too high!
Expectation for anything usefu/helpfull, I understand they’re just cheap.
This might be much but there’s the possibility of opening them up and replacing the battery. Might involve soldering but it’s not hard.
