Sonos Era 100 Wireless Speaker Review

What the Sonos Era 100 actually is

This is Sonos's entry-level smart speaker, the replacement for the long-running Sonos One. It's a compact, single-unit wireless speaker in the $200 to $250 range that plays from Spotify, Apple Music, Amazon Music and basically any service you already use, plus AirPlay 2 and Bluetooth.

The headline upgrade over the old One is real stereo. Inside are two tweeters angled left and right plus a bigger midwoofer, so you get actual separation from one box instead of mono. It's not magic across a giant living room, but on a desk or shelf it reads as wider and more open than its size suggests.

How it performs day to day

Sound is the reason to buy it, and owners broadly agree it punches above its footprint. Bass is fuller than you'd expect from something this small, vocals are clear, and it gets loud enough to fill a kitchen or bedroom without turning to mush. Run Sonos Trueplay tuning and it adapts to the room, which genuinely helps in echoey spaces.

The bigger win is the system around it. Grouping speakers across rooms in the Sonos app is quick and reliable, and that multi-room behavior is the thing competitors still struggle to match. You can also pair two Era 100s as a true stereo pair, or add them as rear surrounds to a Sonos soundbar later.

The flip side is the app. Sonos pushed a redesigned app that frustrated a lot of users with missing features and bugs, and while it has steadily improved, it's still the weakest part of the experience. Bluetooth being included is a quiet relief, because older Sonos speakers skipped it entirely.

The good and the annoying

On the plus side: strong stereo-ish sound for the size, dead-simple multi-room, Bluetooth and AirPlay 2, a USB-C line-in for a turntable or another source (with the optional adapter), and built-in mic support for Amazon Alexa.

The annoyances are real. There's no Google Assistant anymore, only Alexa or Sonos's own voice control. The line-in adapter costs extra. The app reputation still lingers. And Sonos remains a walled garden, so this plays nicest with other Sonos gear and less nicely if you want to mix brands.

Who should buy it, and who should skip it

Buy the Era 100 if you want one great-sounding speaker that can become a multi-room system over time without re-buying everything. It's the right default for most people and the speaker we'd point a first-time Sonos owner toward.

Skip it if you only ever want a single cheap speaker and don't care about the ecosystem, in which case a Bluetooth speaker costs less. Skip it if you're a Google Assistant loyalist. And if you want bigger, room-filling sound for a large open living area, step up to the Era 300 or pair two 100s instead.

The verdict

The Sonos Era 100 is the safe, smart pick in its price range. It sounds better than its size, it's the easiest way into the best multi-room system on the market, and the few real downsides (the app, the missing Google Assistant, the paid line-in adapter) don't outweigh what you get.

If you're buying one speaker that you might turn into three someday, this is it.

Frequently asked questions

Is the Sonos Era 100 better than the Sonos One?

Yes. The Era 100 adds true stereo sound from dual tweeters, a larger woofer, Bluetooth, and a USB-C line-in, all of which the older One lacked. It's a clear upgrade and the One has been discontinued.

Does the Sonos Era 100 work with Bluetooth and a turntable?

It supports Bluetooth and AirPlay 2 out of the box. For a turntable or wired source you use the USB-C line-in, but you'll need Sonos's line-in adapter, which is sold separately.

Should I get one Era 100 or a pair?

One is plenty for a kitchen, bedroom, or desk. Buy two and pair them for a wider, fuller stereo image in a living room, which is a better value than jumping to the larger Era 300 for many people.
