How to use Avantree TV Headphones / Transmitter for two Televisions at home seamlessly?

You can consider the following two items or equivalent items

HT41899 - https://avantree.com/ht41899-bluetooth-dual-headphones-tv-set

Oasis Plus - https://avantree.com/oasis-plus-bluetooth-transmitter-for-tv

Then you can step by step to set them up for your two Televisions:

1. Set up HT41899 with TV1 ;
2. Turn all three devices off;
3. Connect Oasis Plus with TV2 & Pair Oasis Plus with the two headphones, one by one
4. Next use, ALWAYS turn on the headphones first and then the transmitter. One transmitter at a time. 

Of course, you can consider to use other Avantree TV Headphones & transmitters to replace the two devices above to achive the same goal.
