Pixel 5a 5G was the last Pixel that had an audio jack. I held onto mine forever, until Graphene stopped support for the model.

I upgraded to the 7a, and then bit the bullet and bought a separate DAP for music.

The biggest adjustment to using Graphene is often just having to finding open-source app solutions that don't require Google Play, assuming you don't want to run the sandbox. I found the process cathartic, personally.
