TS5 B70 Linux - Wrong audio device for BT Soundbox

Hello, when i use my Sony BT Soundbox as output device it seems to default to the hands free device which cause my audio im listening to bein in a very bad quality and raising the volume by a good amount. I retested this using my built in speaker and it didnt have any problems. Im using Pop os and i can select the hands free device as output (resulting in the same behaviour). On this box hands free seems to be the first offered device.

Hope you can fix this since it makes ts unusable for this environment.
