Troubleshooting Bose speakers, soundbars and headphones
Bose products pair through the Bose Music or Bose app, which also installs firmware updates, and most connection and no-sound problems are cured by a restart, an update and removing and re-adding the product in the app. Soundbars connect to a TV by HDMI eARC or optical cable; if audio is missing or intermittent over HDMI, try another HDMI CEC option in the app or an optical cable.
For Wi-Fi drops, keep other wireless equipment a few feet away from the soundbar and move some access points farther. Headphones and earbuds reset with a button combination that differs by model, so use the model's own page.
