A:AnswerThese come with speaker wire, a USB cable for your computer, and a digital optical cable. The only wire you might need to buy is an aux cable (3.5 mm). But to set it up everything is already inside.
A:AnswerHardwire: You can use RCA connectors, Digital Optical, an Aux cable, or USB cable. They don't support HDMI ARC unfortunately.
You can also use bluetooth, but I'd be concerned about latency issues with that.
