I hooked it up to an old TV set via optics, it turns itself on and off when the TV is started, it is enough to watch movies and music via BT. Don't expect miracles, but it's still nicer than through TV speakers, plus the sound from a smartphone is normal. It’s also enough for a cable like speakers for a PC, everything that is better either without aux or more than 90 cm long. Yes, I would like the sound to be a little more voluminous, but alas, not with my requests
