To be clear, they are wireless because no wires go to the front speakers. But between the two rear speakers and their amplifier are wires that connect to the wall for power. Setup was trivial, and connecting to the LG soundbar was automatic and uneventful. Also bought the speaker stands listed below which worked great! We are very happy with this setup as the LG soundbar with rear speakers is amazing with Dolby and Atmos audio capabilities!
