Does anyone know how to connect 2 Sony headsets to a Pixel 9 Pro so that 2 people can listen at the same time?

Recently, Libby wouldn't allow me to listen to audiobooks when I was in an area with no connection. I tried a bunch of things but even though it was downloaded, it just decided it couldn't play without a background connection.

Does anyone know a fix for this?
