Google Home, Home Mini, and Home Max can now pair with Bluetooth speakers
Google Home devices have a feature that allows them to connect with each other and play audio in sync. This is great if you have a few Home devices spread out through your house. It’s an easy way to get whole-home surround sound. Today, Google has announced a feature that expands upon this functionality with non-Home devices. You can now connect Home devices to Bluetooth speakers.
The Google Home Mini is used as an example of why you might want to do this. On its own, the Home Mini might not be loud enough. Connect a Bluetooth speaker and suddenly you have better audio quality. Google says you can also add connected speakers to Google Home groups for multi-room audio. Putting the speaker in a group means the audio will play from the Home device and Bluetooth speaker.
Connecting a Bluetooth speaker can be done in the Google Home app in the device settings section. Set the Bluetooth device as your default speaker. In this mode, the audio will only play through the connected speaker. Use the Group feature to play audio on all devices at the same time. Keep in mind the Home device is still the brains behind the operation. Connected speakers will not extend the listening ability of the Google Home.
