Google is in the process of rolling out an update to its wireless earbuds, the Pixel Buds ($159.00 at Walmart). I first learned of the update via a post on Reddit, and like the rest of the users commenting on the thread, grew curious as to what had changed and how to apply the update.
I reached out to Google and here's what I learned: The update was first pushed out to Pixel Buds users on Monday, Feb. 5. The update fixes issues with fast pairing and phone call volume.
As for the process, it's all done without you. Continue to use your Pixel Buds as you normally do. The update will download in the background, and the next time you place your Pixel Buds in the case the Pixel Buds will install the new firmware. You will receive an alert on your phone after the update has been successfully installed.
A couple of weeks after the initial update was scheduled for release, my Pixel Buds have finally installed it. Version number 1.1767.6040-G1-61495-541 is what I am now using. As others had reported, a small alert was the only clue that anything had changed.
You can check the firmware version of your Pixel Buds by launching Google Assistant and select Headphone Settings when your Pixel Buds are connected to your Android phone.
