Sonos Era 100 Wireless Smart Speaker
Sonos' best bookshelf speaker — rich stereo sound from a compact form factor with Trueplay tuning, WiFi + Bluetooth + line-in connectivity, and effortless multi-room audio.
Pros
- Genuine stereo sound from single speaker using dual angled tweeters creates impressive soundstage for its compact 7.18" height
- Bluetooth 5.0 addition provides flexibility previous Sonos models lacked, complementing WiFi streaming via AirPlay 2 and Spotify Connect
- Trueplay acoustic tuning automatically optimizes audio for room characteristics, measurably improving sound quality
- Seamless Sonos multi-room ecosystem integration allows synchronized playback and stereo pairing across multiple speakers
- Strong 4.7/5 rating from 4,230 Amazon reviews indicates reliable long-term performance and customer satisfaction
- Touch-sensitive volume slider offers precise, intuitive control superior to button-based systems on competing speakers
Cons
- USB-C line-in requires separate adapter purchase, adding cost and inconvenience for wired audio sources
- Manual Trueplay tuning only works with iOS devices, limiting Android users to automatic tuning only
- Sonos app complexity frequently criticized in reviews, with steeper learning curve than competitors like Google or Amazon
- Premium $164.22 price point significantly higher than basic smart speakers, though justified by audio quality for discerning listeners
Overview
The Sonos Era 100 is the speaker that makes everything else in its price range sound like a compromise. Replacing the beloved Sonos One, the Era 100 delivers a significant leap in audio quality, connectivity, and design — and it does so at a price that's remarkably competitive for what you get.
The sound is the star. Two angled tweeters and a redesigned mid-woofer create a wide, immersive stereo soundstage from a single compact speaker. Bass is punchy and controlled without muddiness, mids are warm and natural, and highs are crisp without harshness. Trueplay tuning — which uses the built-in microphones to analyze your room's acoustics and optimize the EQ — ensures the Era 100 sounds its best regardless of where you place it.
Connectivity is where the Era 100 truly improves over its predecessor. WiFi streaming (AirPlay 2, Spotify Connect, and the Sonos app) delivers the highest quality audio, while Bluetooth 5.0 makes it easy for guests to connect quickly. The USB-C port on the back doubles as a line-in input (with an adapter), so you can connect a turntable, TV, or any wired audio source. This triple-connectivity approach means the Era 100 works in virtually any setup.
Multi-room audio is where Sonos has always excelled, and the Era 100 continues that tradition. Add it to an existing Sonos system and it integrates seamlessly — group it with other speakers for whole-home audio, use two Era 100s as a stereo pair, or pair them as rear surrounds with a Sonos soundbar for immersive home theater.
Voice control via Amazon Alexa is built in (Sonos dropped Google Assistant support), and the physical controls on top — touch-sensitive volume slider and play/pause button — are intuitive and responsive. The compact design looks premium in any room.
The Era 100's only real limitation is that it's a single speaker at $179 — for true stereo, you'll need two ($358 total). But even as a standalone unit, it outperforms most speakers at twice the price.

Full Review
The Sonos Era 100 represents a significant upgrade in the company's compact speaker lineup, delivering genuinely impressive stereo sound from a single unit through its dual angled tweeters and dedicated mid-woofer configuration. The speaker measures 7.18" × 4.72" × 5.12" and weighs 4.44 lbs, making it substantial enough to feel premium without dominating shelf space. Trueplay acoustic tuning automatically adjusts sound based on room characteristics (iOS devices only for manual tuning), while the touch-sensitive volume slider provides intuitive control. With both WiFi streaming (AirPlay 2, Spotify Connect) and Bluetooth 5.0, it offers flexibility that previous Sonos speakers lacked, though the USB-C line-in requires a separate adapter purchase. The built-in Amazon Alexa works reliably for voice control, and compatibility with Sonos's multi-room ecosystem remains a standout feature.
At $164.22, the Era 100 sits in an interesting position within the smart home category. While the Amazon rating of 4.7/5 from 4,230 reviews reflects strong user satisfaction, potential buyers should understand this is primarily a premium speaker with smart features, not a smart home hub. Compared to category alternatives like the Lutron Caséta dimmer kit ($114.95) or Google Nest products, the Era 100 serves a fundamentally different purpose—it's about audio quality first. Sound performance genuinely rivals speakers costing significantly more, with clear highs, detailed mids, and surprising bass depth for the size. The stereo separation from a single speaker is notably effective, though pairing two Era 100s in stereo mode (doubling the investment) unlocks the full potential. The Sonos app interface has improved but still receives criticism for complexity, and the ecosystem lock-in means you're committing to Sonos's platform. For audiophiles wanting smart home integration or existing Sonos users upgrading, this delivers excellent value. However, those seeking basic Bluetooth speakers or comprehensive smart home control hubs might find better options elsewhere.
