AirPod PRO2 connect to BT adaptor but no sound
Wanting to watch films with my AirPod Pro2 in an airplane, I bought a Bluetooth transmitter. AirPod does connect to the transmitter, but no sound. I checked the transmitter with a Bose BT speaker - works fine. How come Apple sells $300 earphones that does not operate properly with non-Apple devices ?
