João Gouveia posted a question in LG webOS Smart TV QuestionsHi, I have a Led 4K 43UH620V. I want to buy an headphone wireless that is compatible with this model (I read that only models with the LG Sound Sync will do). Also I read here in this Forum that the HBS 700, 730 and 800 are compatible with LG sound sync but I also read that some people that chose one of this models didn't work. Did something change, did LG launch newer models, as these are descontinued? Many thanks. Best Regards.
