In this article, we'll look at how to add headphone functionality to a Chromecast. Current models are easy to connect, but older models may require you to invest in an app or transmitter.
Connect Bluetooth speakers and headphones with Chromecast to Google TV
If you have the latest Chromecast, which first hit the market in 2020 with a dedicated remote, setting up your headphones isn’t much different than pairing them with your phone.
Turn on your Chromecast and go to your profile in the top right corner. Choose Settings > Remotes and Accessories > Pair Remote or Accessories.
Put your Bluetooth headphones in "pairing" mode. You can optionally disable Bluetooth devices that you do not want to connect to your Chromecast.
