Is there currently anyway possible to perform both of these actions at once? For example while using the galaxy buds live is it possible to listen to music with the left bud and have a call going on the right bud?
have you tried this? (you may need to use a different Bluetooth earpiece for your phone call however, but it could work as a work around
Go to settings, then sounds and vibration, scroll to the bottom and click on Separate app sound, then click turn on now. it allows you to "forward" music to a certain Bluetooth connected speaker...thus in theory, phone should play out the other earpiece.
