I've got a Firestick "Pro Remote" that I bought to use with my Firestick 4K Max. It's got a dedicated headphone button on the remote, so all I have to do is click that button when I want to use my Bluetooth headphones to listen to the TV. This is super convenient. Since the Onn 4K Pro remote does not have this button, what would be the easiest way for me to use my Bluetooth headphones if I switch from the Firestick to the Onn box? What's the process to get them "turned on" without that button on the remote?
Thanks in advance!
