I just dropped $1700 on a 4K TV and "wireless" Sound Bar from LG. The setup instructions of the sound bar (6 pictures in a manual 2 pages long), show how to connect them with - optical cable - HDMI Those are the options. How is this a wireless sound bar if it requires cables?? Not that it matters; it doesn't work no matter which way I slice it. I hate hate hate hate hate technology.
