I can’t find a solution to my problem, but that seems very similar in many other topics.
I found a little trick that helps with Razer Audio.
My left earbud turns off after seconds when it isn’t playing something.
I open the case and then I autopair it with my phone, and if it’s already playing something they work fine.
But whenever I stop the music or if I wasn’t playing nothing the left earbud turns off (only the left one)
I also noticed that if I have bluetooth off and I open the lid of the case both earbuds try to connect to something, but in a few seconds the left earbud turns off even if it’s still in the case.
The second problem is with Razer Audio app that can’t find the earbuds, and I think it’s because of the left earbud problem.
I found this trick, if I use Razer app in floating window and I play something to avoid that the earbud turns off it just work s fine with no problems at all.
