NOTE: The dual headphones support function
works with most headphones but not all.
Certain true wireless earbuds in particular do
not work well with Bluetooth transmitters'
dual headphones mode. If you're not getting
audio while dual linked, try turning the
a ected headphones o and then on again.
In some cases, dual pairing with Airpods may
trigger their audio MUTE function. If this
happens, put them back in their charging
case (with the lid open) for 2 seconds, then
take them out again to return them to
normal. This may help to solve the problem.
