Hi Julian and folks,
I successfully connect AirPods and Taotronics TT-BA01 twice. So let me share how to connect the devices.
1. Reset Bluetooth transmitter :
1) Turn on the transmitter (flush blue LED)
2) Push power switch twice
3) Turn off the device
4) Repeat 1) to 3) several times if this procedure does not work.
2. Paring AirPods and Taotronics :
1) Turn on the transmitter and push power switch until the device starts blinking LED in blue and red alternately.
2) Make AirPods paring mode
3) When Transmitter's LED gets stable red and AirPods case's white LED turns off, you get the paring.
Note : I get the paring in terms of :
1) AirPods are disconnected from iPhone7 and Apple Watch in advance.
2) Turn off other Bluetooth devices (Android device, other Bluetooth ear phone etc.)
Now I'm enjoying TV programs / Am*z*n Prime (Fire stick) / Internet & iTunes on Macbook Pro early 2012.
