For years, my living room was a battlefield of wires. I had a decent, traditional hi-fi system, but the tangle of speaker cables, the bulky amplifier, and the need to physically connect a device every time I wanted to play a song felt increasingly archaic. The promise of wireless audio was alluring, but early Bluetooth speakers often sacrificed sound quality for convenience, delivering tinny, compressed audio that lacked any real depth. I, like many others, was searching for the holy grail: a single, elegant speaker that could genuinely fill a room with rich, detailed sound, connect seamlessly to any device, and integrate intelligently into my home. The frustration of mediocre sound is real; it can turn a favourite album into background noise and a relaxing evening into a hunt for the right cable. The Sonos Era 100 Smart Speaker enters this landscape not just as another smart speaker, but as a potential solution to this long-standing dilemma.
- Featuring next-gen acoustics and new levels of connectivity, Era 100 transforms any room with the finely tuned stereo sound and rich bass your music deserves
- Powered by a 47% faster processor, the next-gen dual-tweeter acoustic architecture produces detailed stereo separation while a 25% larger midwoofer deepens the bass
What to Consider Before Buying a Bookshelf Speaker
A Bookshelf Speaker, especially a smart one like this, is more than just an item; it’s a key solution for decluttering your audio life while simultaneously upgrading its quality. It solves the problem of wanting immersive, high-fidelity sound without the complexity and space requirements of a traditional component stereo system. The main benefits are convenience, superior sound quality compared to standard portable speakers, and the ability to build a multi-room audio system over time. These speakers are designed to blend into your home on a bookshelf, kitchen counter, or nightstand, providing a powerful soundstage from a compact and stylish form factor. If you value both aesthetics and audio performance, this category is tailor-made for you, and the Sonos Era 100 Smart Speaker is a prime example of this philosophy.
The ideal customer for this type of product is someone facing the challenge of limited space but unwilling to compromise on sound. This includes apartment dwellers, music enthusiasts looking to add audio to a bedroom or office, or anyone starting their journey into high-quality home audio. It’s for the person who wants to control their music with their voice, stream from any service via Wi-Fi, and have the flexibility of Bluetooth for guests. However, it might not be suitable for those who are dedicated audiophiles with an existing investment in passive speakers and high-end amplifiers, as that involves a completely different audio philosophy. It’s also less ideal for someone seeking a purely portable, battery-powered speaker for outdoor use, as this is a corded, indoor device.
Before investing, consider these crucial points in detail:
- Dimensions & Space: The term “bookshelf speaker” can be misleading. Always measure your intended space. The Sonos Era 100 Smart Speaker stands at 18.35 cm tall, making it compact enough for most shelves and counters, but you must ensure there’s adequate clearance and a nearby power outlet. Consider the acoustics of the space as well; a speaker placed in a tight corner will sound different than one in an open room.
- Capacity/Performance: This is where the magic happens. Look beyond just wattage. Key performance indicators for a smart speaker include the driver configuration—the Era 100’s dual-tweeter setup is a significant feature for creating stereo sound from a single box. Also, consider the “smart” capabilities like room-tuning technology (Sonos calls it Trueplay), which can dramatically improve performance by adapting the sound to your specific environment. You can explore its full acoustic specifications to see how it achieves this.
- Materials & Durability: A well-built speaker isn’t just for show; it contributes to sound quality by reducing unwanted vibrations and resonance. The Sonos Era 100 Smart Speaker uses a dense, premium-feeling polymer chassis that feels substantial and inert. Cheaper speakers might use thin plastics that can rattle at high volumes, so investing in good build quality ensures both longevity and better audio fidelity.
- Ease of Use & Maintenance: In the age of smart devices, the user interface is paramount. Most interaction will be through a mobile app, so consider its design and functionality. The Sonos app is known for its robust ecosystem and support for virtually all streaming services. Long-term maintenance is minimal, usually just occasional dusting and ensuring the software is kept up to date through automatic firmware updates.
Choosing the right speaker is about matching its capabilities to your lifestyle and space. The blend of performance, connectivity, and design is what sets premium models apart.

First Impressions: Unboxing a Modern Audio Icon
From the moment you lift the box, the Sonos Era 100 Smart Speaker feels like a premium product. Sonos has mastered the art of packaging, creating an unboxing experience that is both simple and satisfying. Inside, the speaker is securely nestled in eco-friendly materials, accompanied only by a colour-matched power cord and essential documentation. Our white review unit was pristine and elegant. Lifting its 2kg weight, the speaker feels dense and impeccably constructed, with no creaks or flex. Its new cylindrical form is a subtle evolution from the more rectangular Sonos One, making it feel more like a deliberate design object. The matte finish resists fingerprints, and the wraparound grille is seamless.
The top surface features new, intuitive touch controls, including a clever recessed volume slider that is a tactile delight to use. Around the back, the clean design continues with just a power port, a USB-C port for line-in and ethernet adapters, and a physical switch to disable the microphone for privacy. Setting it on the kitchen counter, it immediately blended in, looking both modern and understated. It gives the impression of a device built with precision and a deep understanding of what makes a product feel special, a feeling that only grows when you power it on. It’s an impressive piece of hardware before a single note is even played, and you can see the different colour options available.

Performance in Detail: A Deep Dive into the Era 100’s Sound and Smarts
A speaker can look beautiful on a shelf, but its true worth is only revealed when you press play. We put the Sonos Era 100 Smart Speaker through its paces for over a week, testing it in various rooms with a wide range of genres, from the delicate acoustics of folk music to the complex layers of classical and the demanding bass of electronic tracks. This wasn’t just about listening; it was about evaluating its core promises of stereo sound, enhanced bass, and seamless connectivity.
The Acoustic Architecture: A Genuine Leap into Stereo Sound
The single most significant upgrade in the Sonos Era 100 Smart Speaker is its new acoustic architecture. Sonos replaced the single tweeter of the older Sonos One with two angled tweeters, each firing outwards to the left and right. This isn’t a marketing gimmick; it’s a fundamental shift that allows a single speaker to produce a true stereo soundstage. We tested this with tracks renowned for their stereo imaging, like Dire Straits’ “Money for Nothing” and The Beatles’ “Abbey Road” medley. The effect was immediately apparent. Instead of a mono point source, the sound had a tangible width and separation. Instruments felt placed across a virtual stage in front of us, a feat that is incredibly difficult to achieve from such a compact enclosure. This dual-tweeter design is a feature that really sets it apart in the single-speaker market.
Complementing the crisp highs from the tweeters is a new midwoofer that is 25% larger than its predecessor. This directly translates to bass performance, and we were frankly astonished by the depth and power this speaker can produce. Listening to James Blake’s “Limit to Your Love,” the subterranean bass drops were rendered with authority and control, without any of the muddy boominess that plagues lesser speakers. The bass is tight, musical, and detailed. This aligns perfectly with user feedback, where one reviewer noted they were “surprised by the amount of bass and overall clarity.” Another described the audio as “smooth and buttery as tape audio,” a sentiment we echo. The sound signature is rich and warm, embellishing music in a way that is incredibly pleasing and non-fatiguing, even over long listening sessions.
Connectivity Reimagined: Wi-Fi, Bluetooth, and the Adapter Caveat
For years, the biggest request from Sonos users was the addition of Bluetooth, and with the Era 100, they have finally delivered. This dual-connectivity approach is the speaker’s greatest strength in terms of versatility. Wi-Fi remains the backbone of the Sonos experience, providing the most stable, highest-quality connection for streaming and multi-room audio. It’s how you access your entire music library and integrate the speaker with other Sonos products. But the addition of a simple Bluetooth pairing button on the back is a game-changer for convenience. When a friend comes over and wants to play a track from their phone, there’s no need for them to download the Sonos app or join my Wi-Fi network. One press of the button, and they’re connected. It’s seamless and works flawlessly.
The Sonos Era 100 Smart Speaker also introduces line-in connectivity, allowing you to connect external sources like a turntable or an MP3 player. This is a fantastic feature for vinyl lovers, but it comes with a significant catch: it requires the proprietary Sonos Line-In Adapter, which is sold separately and connects via the USB-C port. We tested this with a Pro-Ject turntable, and it worked perfectly, piping the analogue audio through the speaker and even allowing us to stream the vinyl playback to other Sonos speakers in the house. While the functionality is excellent, we share the sentiment of users who find the need for a specific, extra-cost dongle a bit frustrating, especially when a standard 3.5mm jack could have been included. It feels like a missed opportunity for true plug-and-play simplicity.
The Brains of the Operation: The Sonos App and Trueplay Tuning
The physical speaker is only half the story; the other half is the Sonos S2 app. This is the central command for your entire system. The initial setup of the Sonos Era 100 Smart Speaker is handled exclusively through this app. As one user correctly pointed out, this is not well explained in the box. You must use a smartphone. For us, the process was quick and straightforward: plug in the speaker, open the app, and it’s discovered within seconds. The app then guides you through connecting to Wi-Fi and adding your music services. However, we can easily see how a less tech-savvy user might be confused by the lack of traditional instructions.
The app’s crown jewel is Trueplay tuning. This technology uses the microphone on your smartphone (for iOS) or the speaker’s own built-in mics (a new feature called Quick Tuning, available for all users) to analyze the acoustic properties of your room. You walk around the space while the speaker emits a series of tones, and the app creates a custom EQ profile to optimize the sound. We tested this in two distinct environments: a small, acoustically-treated office and a large, open-plan living room with lots of reflective surfaces. The difference before and after Trueplay was not subtle; it was transformative. In the office, it tamed a slightly boomy bass resonance caused by corner placement. In the living room, it enhanced vocal clarity and tightened up the entire soundstage. This is a powerful feature that ensures you’re getting the best possible sound no matter where you place the speaker, and it’s a compelling reason to invest in the Sonos ecosystem.
What Other Users Are Saying
Across the board, the consensus from other users is overwhelmingly positive, particularly regarding sound quality. Many echo our findings, with one owner stating, “the sound is excellent… it makes digital music sound as smooth and buttery as tape audio.” This unique, pleasing character of the sound is a recurring theme. The addition of Bluetooth is another frequently praised feature, with one long-time user asking, “why did I hold off trading up for so long?” a testament to how much this feature was needed.
However, the feedback isn’t without its critiques, which provide a balanced real-world perspective. The most common point of friction is the setup process. As one detailed review explained, “The Era 100 is ENTIRELY set up through the mobile phone app… it’s not explained very well.” This is a crucial piece of information for potential buyers. Another valid point raised by several users is the cost of entry, especially for a stereo pair. “It’s an amazing speaker, but I feel you need 2, and that is very expensive,” one user noted. While one speaker is impressive, two units paired for stereo are a significant financial commitment. We found this feedback to be highly relevant, confirming that while the performance is top-tier, the user experience and cost can be hurdles for some.
How the Sonos Era 100 Compares to the Competition
The Sonos Era 100 Smart Speaker doesn’t exist in a vacuum. It faces stiff competition from within its own family and from more traditional audio brands. Understanding where it sits in the market is key to making the right choice for your needs.
1. Sonos One SL Speaker
- Compact design fits just about any space and put it on your kitchen countertop or tuck it away on your office bookshelf
- Airplay 2 on Sonos - stream sound directly from your iPhone or iPad and ask Siri to play Apple Music
The Sonos One SL is the direct predecessor to the Era 100 and remains a viable option. Its primary differences are that it delivers mono sound from a single tweeter/midwoofer combo, and it lacks both Bluetooth and line-in connectivity. For someone already deep in the Sonos ecosystem who simply wants to add a speaker to a small room like a bathroom, or use a pair as rear surrounds for a Sonos soundbar, the One SL can be a more budget-friendly choice. However, for a primary, standalone speaker, the Sonos Era 100 Smart Speaker is a massive upgrade, offering a far wider stereo soundstage and much greater flexibility with its added connection options.
2. Edifier R1280DB Active Bookshelf Speakers
- BLUETOOTH WIRELESS - Popular classic bookshelf speakers now can be enjoyed without the hassle of wires. Simply connection to an iPhone, Android, Tablet, PC or Mac.
- STUDIO SOUND QUALITY - Naturally fine tuned sound reproduction from 4 inch bass and 13mm silk dome tweeter.
The Edifier R1280DB represents a more traditional approach to bookshelf audio. For a significantly lower price than a single Era 100, you get a pair of active speakers that provide true, physical stereo separation out of the box. They offer a wealth of physical inputs, including Optical, Coaxial, and dual RCA inputs, alongside Bluetooth. This makes them ideal for a user who wants to build a dedicated listening station for a turntable, PC, or TV. What you sacrifice are the “smart” features: there is no Wi-Fi streaming, no multi-room integration, no voice control, and no advanced room correction like Trueplay. It’s a choice between the smart, integrated ecosystem of Sonos and the straightforward, input-rich world of traditional active speakers.
3. Edifier R1280DBs Wireless Bookshelf Speakers
- BLUETOOTH 5.0 - Pair the speaker with your smartphone, tablet, Mac, or laptop to play music wirelessly, no need to deal with messy wires.
- SUB OUT AND OPT/COAX INPUTS - Subwoofer output with automatic detection and built-in crossover. Optical and coaxial inputs to ensure a lossless connection to TVs and computers.
The Edifier R1280DBs is a subtle but important variation of its sibling. It offers the same great value and connectivity but adds a crucial feature: a dedicated subwoofer output. This is a game-changer for bass enthusiasts or anyone using the speakers for movies or gaming. It allows you to easily add a powered subwoofer to create a powerful 2.1 system, providing low-end grunt that the Sonos Era 100 Smart Speaker, on its own, cannot match. Again, the trade-off is the complete absence of the seamless Wi-Fi and multi-room capabilities that define the Sonos experience. This Edifier model is for the user who prioritizes bass extension and a traditional setup over smart home integration.
Our Final Verdict: Is the Sonos Era 100 Smart Speaker the One to Buy?
After extensive testing, we can say with confidence that the Sonos Era 100 Smart Speaker is a triumph. It thoughtfully addresses the shortcomings of its predecessor and sets a new high-water mark for what a single smart speaker can achieve. The leap to true stereo sound from one unit is remarkable, creating an audio experience that is expansive and deeply engaging. Coupled with its powerful, controlled bass, versatile connectivity options, and the intelligence of Trueplay tuning, it delivers on nearly every promise.
While the app-only setup can be a hurdle for some and the need for a separate adapter for line-in is a slight annoyance, these are minor issues in an otherwise stellar package. It is the perfect speaker for the modern music lover—someone who values convenience, quality, and design in equal measure. Whether you are starting your premium audio journey, expanding a Sonos system, or simply want one fantastic-sounding speaker for your office or kitchen, the Era 100 is an exceptional choice. If you are ready to invest in a superior listening experience that will seamlessly integrate into your life, the Sonos Era 100 Smart Speaker earns our highest recommendation.
