I received the Google Pixelbuds yesterday as promised by USPS and so far I am very happy with how they work. They were discovered by my Pixel 4a and setup went smoothly. The Pixelbuds are associated to my Google account and so my work phone that runs Android and knew about the Pixelbuds and displayed a notification to associate it and install the Pixebuds app. More first impressions notes on my tech information page.
