I had the same problem with JBL TUNE500BT Headphones on Ubuntu 20.04. I did a kernel update to 5.8.9-050809-generic version using ubuntu-mainline-kernel.sh script [1]. I also uninstalled ofono and ofono-phonesim which I installed earlier when trying to fix this problem and reverted any changes I did to the default.pa file. It seems to be working now, but audio quality is awful when using HSP/HFP, which is related to another bug [2]. I don't know if it's a good solution, but maybe it will help someone.
