Reference excerpt

The Pixel Buds is a line of wireless earbuds developed and marketed by Google. The first-generation Pixel Buds were launched on October 4, 2017, at the Made by Google launch event, and became available for preorder on the Google Store the same day. They integrate with the Google Assistant and support real-time translation with Google Translate. The second-generation Pixel Buds (sometimes known as Pixel Buds 2 or Pixel Buds 2020 to distinguish them from the first-generation earbuds) were announced at the Pixel 4 hardware event on October 15, 2019. They were released on April 27, 2020 and debuted to positive reviews. In June 2021, Google announced the Pixel Buds A-Series, a mid-range variant of the second-generation Pixel Buds. In May 2022, Google announced the Pixel Buds Pro, a premium variant of the Pixel Buds with additional features including active noise cancellation. In August 2024, Google announced the Pixel Buds Pro 2 with Gemini and with improved active noise cancellation.

Models

First generation 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 an "open-air" design, where the driver rests just outside the user's ear canal, and there is relatively little isolation from outside sounds. Each earbud is secured physically into the user's concha by a short loop of the cord; the length of the loop is individually adjustable to better fit each user. 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 case also has a button to pair the earbuds manually and LED indicators to communicate the state of charge and pairing readiness. The battery in the charging case has a 2.39 W-hr capacity, providing enough energy for 24 hours of earbud operation.

Features The distinguishing feature of Pixel Buds is their integration with the Google Assistant, a smart voice assistant. This allows the earbuds to translate conversations in real-time, among other standard features such as web search and media connectivity. It supports translation of 40 different languages. 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. Double-tapping will read a notification aloud. Triple-Tapping will connect/disconnect the Pixel Buds from their source. The Pixel Buds do not have ear-sensing features, so audio playback does not automatically pause and the touch-sensitive surface remains active after the earbuds are removed; the surface is deactivated once the earbuds are seated properly in the charging case. The Pixel Buds also introduced a "fast pair" feature to Android; with a smartphone that runs Android 6.0 (Marshmallow) or higher with the Bluetooth radio active, opening the lid of the case will bring up a notification prompting the user to pair the earbuds with the phone. The button of the case also can be used to pair the Pixel Buds manually as needed.

Reception 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. In 2018, Google announced "Google Translate is available on all Assistant-optimized headphones and Android phones." 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

The second-generation Pixel Buds 2 were first announced at a Google hardware event on October 15, 2019 and released in the United States in April 2020. They were released in Australia, Canada, France, Germany, Ireland, Italy, Singapore, Spain, and the United Kingdom in July 2020. Initially, only the Clearly White color was available; the other three colors (Oh So Orange, Quite Mint (green), and Almost Black) were released four months later in the United States on August 20, 2020. Google quietly discontinued the orange color in April 2021, and all second-generation Pixel Buds were discontinued in favor of the Pixel Buds A-Series shortly after the latter were announced in June 2021.

Worked examples

Example 1 — a first encounter with Pixel Buds

Start with the simplest possible case. Write down what Pixel Buds claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pixel Buds before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pixel Buds ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pixel Buds

In research: Pixel Buds appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pixel Buds in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pixel Buds is common in secondary-school and first-year university syllabi. It links to neighbouring topics Google Pixel, Google hardware, Headphones, so understanding it makes those chapters shorter.
In everyday life: Look for Pixel Buds outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
