One of the most annoying issues for travelers is that your Bluetooth headset won't work with the seatback entertainment system on an airplane. If you have a pair of in-ear headphones with a headphone jack, just bring the appropriate cable to use them.
But what if you want to use your AirPods, AirPods Pro or other true wireless earphones with your seatback system? In-flight entertainment systems usually have a 3.5mm headphone jack on the armrest. To use a bluetooth headset, you need to connect a bluetooth transmitter to the headphone jack and pair with the headset. This makes it possible to use AirPods, AirPods Pro or other true wireless earphones with the seat back system.
