Question about Samsung Galaxy Buds2 Pro

The Galaxy Buds 2 pro are said to be compatible with Samsung Smart TVs from 2018. What is the situation with the predecessor model, the Galaxy Buds 2? And does anyone have general experience with the combination of Galaxy Buds 2 Pro (or Galaxy Buds 2) with Samsung Smart TVs? Does it work well to connect the Buds to the Samsung Smart TV (similarly simple as in combination with a smartphone) or do I have to adjust something each time until the connection is established? And how do I have to imagine that I want to watch/listen to TV with the Buds instead of via the Smart TV speakers, do I have to establish the connection with the help of the smartphone or is the connection from the Buds to the TV established automatically? I.e. how does the TV know that it should connect to the buds?
