Sonos OPADPWW1BLK Optical Audio Adapter, Black

Connect your Beam or Arc soundbar to any TV with an optical audio output. This compact 4.5" adapter cable bridges the gap between your TV's TOSLINK optical connector and your soundbar's HDMI input, making it perfect for older televisions without HDMI audio support. Simply plug the optical end into your TV and connect an HDMI cable (sold separately) to your soundbar for seamless audio integration.
