A:Answer Wireless can be a vague term. This product requires to be wired into a power supply - that's one application of the term. If the device producing the sound signal (tv, phone, computer, etc) has Bluetooth capability, you can connect to it without hard-wiring to the device. If not, you will need to connect via wires such as RCA cables. I have it connected via RCA to my tv, but when I want to stream music to it from my phone, I pair my phone to it via Bluetooth wirelessly
