How to connect 2 Bluetooth audio headsets to an Android phone? How can two people listen to audio on an Android phone over Bluetooth?  I.e. they have two Bluetooth headsets and want to pair both at the same time?
As in most things, it depends. In this case, since you do not state your device, I will demonstrate from mine, a Samsung 8, running Android 9 (One UI). It explicitly allows dual Bluetooth through settings. If this is your device, click through to it at

Settings &gt; Connections &gt; Bluetooth &gt; Advanced &gt; Dual Audio &gt; ON

The setting allows sound to two different Bluetooth devices.

If your device is different, look for the capability along a similar setting path.
