I just installed it this summer using ArchInstall. I’m on Pipewire as well.

I’m looking to use the microphone too.

It works great but only with the wireless dongle. It works poorly with Bluetooth, and doesn’t work at all with direct USB connection. My original question was hoping to see if I could quickly resolve direct USB connection with the headphones since that seems like it may be the easier to get a great connection.

I’m also on ArchLinux!

I use a Navidrome server and ProjectBlue app on my Android. I haven’t figured out how to download music for offline use by using my ProjectBlue app though.
