This soundbar can be plugged into your tv through an optical or HMDI cable. It also has san auxiliary input and bluetooth capability which allow you to connect the soundbar to pretty much everything, like your computer, smartphone, etc. to play your music and many other stuff. The reason it is on sale is because I am moving abroad and it is to expensive to bring it with me. There not even a single scratch on it, so it looks like new, and it comes with its control, and an optical cable. (I also have the box it came with when I bought it and the instruction manual)
If you have any questions please feel free to contact me.
Cheers,
