Key takeaways

Sonos belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sonos to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sonos from memory before moving on to harder problems.

Reference excerpt

Sonos, Inc. is an American audio equipment manufacturer headquartered in Santa Barbara, California. The company was founded in 2002 by John MacFarlane, Craig Shelburne, Tom Cullen, and Trung Mai. Sonos has partnered with over 100 companies that offer music services, including Pandora, iHeartRadio, SiriusXM, Apple Music, Spotify, Tidal, MOG, QQ Music, YouTube Music, Deezer and Amazon Music. Sonos products work with the three major voice assistants: Amazon Alexa, Google Assistant, and Apple Siri, although the last is currently only supported through Apple's Home app. In 2019 Sonos acquired Snips SAS, a privacy-focused AI voice platform for connected devices with the goal to bring a music-specific assistant to its devices. Sonos partnered with Audi to provide premium sound systems in several of their entry-level and compact models. The Sonos Premium Sound System can typically be found in the following vehicles, available as an option or standard on higher trim levels, Audi Q4 e-tron (and Sportback), the first vehicle to feature the Sonos audio system. Audi A3 (and RS3) available as part of Audi's Technology Pack. Audi Q3, upgradable to a 15-speaker Sonos system via the Technology Pack. Audi A1 and Q2, included as available premium upgrades in smaller Audi models.

History

Corporate, financial, and marketing history Sonos was founded as "Rincon Audio, Inc." in August 2002 by John MacFarlane, Craig Shelburne, Tom Cullen and Trung Mai, with MacFarlane wanting to create a wireless service. The company changed its name to "Sonos, Inc." in May 2004. During 2004, MacFarlane brought prototypes of the first Sonos products to several industry events, including the June 2004 "D2: All Things Digital" conference in Carlsbad, California and the December 2004 Digital Music Summit. It was reported that in D2 Steve Jobs told MacFarlane that the Sonos controller's scroll wheel might have violated Apple patents related to the iPod. Sonos aimed to begin shipping its products in the fourth quarter of 2004 but missed that deadline. The company first introduced its products to the market in January 2005 and first shipped them in either January or March 2005. In May 2005, Sonos announced that its initial product line would go on sale in the United Kingdom in the following month. The company has continued to broaden its international sales, for example to Japan in 2018. In May 2012, Sonos opened the Sonos Studio in Los Angeles, a studio and art gallery in which art was exhibited along with Sonos' products for free, and featured events with artists like Beck, The Lonely Island and Solange, and released a video about its development. The Los Angeles location was closed in 2018; a London location remains open. In December 2013, the company was estimated to have raised $118 million in venture funding, including a $25 million round; its investors included Kohlberg Kravis Roberts, Redpoint Ventures and Elevation Partners. In April 2014, Google and Sonos introduced deep integration features that allowed users to play and control Google Play Music through Sonos devices. In January 2015, Sonos was rebranded by Bruce Mau Design, with a new visual identity and improved logotype that was created over the span of four years, from 2011 to 2014. There have been other brand refreshes, including one in 2019. In February 2016 Sonos also released a study called Music Makes it Home Study. In March 2016, CEO John MacFarlane announced the company's shift to focus on streaming music services and voice control instead of local playback, and laid off some employees. In July 2016, the company opened its first Sonos Store in SoHo. Sonos announced the store's closure in June 2020. In September 2016, the company announced that its products would become available at Apple Stores. In January 2017, MacFarlane announced via the company's blog that he would be stepping down from his role as CEO, and that he would be succeeded in this position by former COO Patrick Spence. In December 2017, IKEA and Sonos announced a collaboration to build Sonos' technology into furniture sold by IKEA. In May 2025, Sonos announced the partnership was ending. In August 2018, Sonos went public, trading on the NASDAQ under the symbol SONO. In November 2019, Sonos acquired Snips SAS, a privacy-focused AI voice platform for connected devices with the goal to bring a music-specific assistant to its devices. In January 2020, Sonos sued Google over copyright infringement relating to several patents, including the ability to sync audio over multiple devices. In August 2021, a judge ruled in favor of Sonos. The International Trade Commission also ruled in favor of Sonos. As a result, Google was ordered to remove certain features from its devices, including group volume control. Google was ordered to pay Sonos $32.5 million in damages. However, a judge tossed out the verdict in October and criticized Sonos for abusing the patent system. Following the verdict, Google redeployed the features it had previously removed. In April 2020, Sonos revealed a new "sonic logo" composed by Philip Glass, featuring an ensemble of 21 musicians. The logo will be heard in the listening experience of Sonos Radio, an Internet radio streaming service that was unveiled by the company the same month. In June 2020, Sonos announced plans to lay off 12% of its workforce, close its New York store and six of its offices, and cut its top executives' pay by 20% for three to six months, in response to the economic disruptions caused by the COVID pandemic. In November 2020, Sonos launched "Sonos Radio HD", a paid ad-free tier of Sonos Radio. In April 2022, Sonos acquired Mayht, a Dutch speaker-technology start-up co-founded by Timothy Scheek, for US$100 million. Mayht had developed a compact transducer design that Sonos later introduced as Sound Motion in its Arc Ultra soundbar in 2024. In May 2023, Sonos reported a 24% drop in revenue. Sonos then laid off 7% of its workforce—130 employees—in June. In August 2024, Sonos laid off another 100 employees. Several of its customers support locations will also close, including one in Amsterdam.

Worked examples

Example 1 — a first encounter with Sonos

Start with the simplest possible case. Write down what Sonos 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 Sonos 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 Sonos 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 Sonos

In research: Sonos 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 Sonos 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: Sonos is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2002 establishments in California, 2018 initial public offerings, American companies established in 2002, so understanding it makes those chapters shorter.
In everyday life: Look for Sonos 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.
