Small earbuds like the Google Pixel Buds tend to get lost. Thankfully, it looks like you might be able to keep track of them soon. The second-generation wireless earphones show up on the Find My Device app for a lot of Pixel Buds owners. According to 9to5Google, logging into Find My Device on Android or the web will list connected Pixel Buds.
As it exists now, the integration shows what phone they were "last seen connected to" and the time and date. It's shown against a map with a pin showing a generic headphones icon against a gray background. If you wanted to try the "find device" query on Google Search, it doesn't work right now. Location integration isn't showing up in the Pixel Buds app under the Find device menu, either.
An upcoming update might bring these features all together soon. For now, we're getting a taste of what to expect. And as far as functions go, this integration is a useful one.
