The Pixel Buds were announced at Google's annual hardware event on October 4, 2017, alongside its second-generation
Pixel 2 smartphone. Color choices for the Pixel Buds complemented the Pixel 2, and carried the same names: Just Black, Clearly White, and Kinda Blue, referring to the color of the circular plastic cap visible in the ear. After the second-generation Pixel Buds were announced in October 2019, Google removed the first-generation from its store.
Physical design The industrial design team was led by Gina Reimann. The first-generation Pixel Buds consist of two earbuds linked by a fabric-covered cord, which connect wirelessly over a
Bluetooth 4.2 connection. The earbuds are powered by a 120 mA-hr battery stored in the left earbud, and provide five hours of listening time before needing to be recharged. The earbuds are stored in a fabric-covered case with an internal battery and USB-C connection; the storage case charges the earbuds, and the USB-C port charges the battery of the storage case. Once the earbuds have been placed in the appropriate sockets, the cord connecting them is wound and stored in a specific manner, illustrated on the inside of the upper lid, to allow the case to close. The battery in the charging case has a 2.39 W-hr capacity, Based on the October 2017 demonstration, early coverage compared the Pixel Buds' translation capabilities to that of the fictional Babel fish from ''
The Hitchhiker's Guide to the Galaxy by Douglas Adams; however, in a review for Wired'', James Temperton called the feature as released "a bit of a con", as the Pixel Buds merely provided a microphone and speaker for transcription and
machine translation powered by
Google Translate running on a smartphone: "to speak English to a German who then replies in German that's translated into English you will need: two Google Pixel 2 phones and two Google Pixel Buds headsets. And even then you'll likely spend most of the conversation staring awkwardly into middle-distance while Assistant tries to work out what the hell is going on. Long rant cut short: you don't actually need the Pixel Buds to do this, they're an entirely pointless accessory." The surface of the right earbud is touch-sensitive: a tap will play or pause audio, swiping forward or backward will raise or lower the volume, respectively, and tapping and holding will bring up the Google Assistant prompt.
Criticism Reception of the Pixel Buds was mostly negative, with much of the criticism aimed towards its storage case and the awkward steps required to seat the earbuds and wind the cord properly. Google's support page tells the user to "press down to make sure the charging pins are firmly in place", despite the presence of magnets to help align and retain the Pixel Buds in their storage case. By opening the service to more devices, researcher Matic Horvat hypothesized that Google was seeking more inputs to train its
neural network for real-time, natural-language
speech recognition. == Second generation ==
