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.

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.
