The Sonos Era 300 is a 2023 release from this manufacturer. Available in both Black and White, this stereo speaker is designed for home use, and it's easy to integrate with your existing Sonos products, as you can even pair it with soundbars like Sonos Arc Ultra to form the Sonos Ultimate Immersive Set with Arc Ultra. Along with the Sonos Era 100, it's the first speaker from the manufacturer to include Bluetooth connectivity in addition to traditional Wi-Fi support. Premium sound features like Trueplay room correction let you optimize the speaker's output based on the unique acoustics of your room, and now, Android users can take advantage of the 'Quick Tuning' option, too. Plus, Dolby Atmos support lets you make the most of Dolby Atmos Music on eligible streaming platforms like Apple Music.
Our Verdict
The Sonos Era 300 is decent for music. Like most premium speakers on the market, this device features a room-correction tool that automatically optimizes audio reproduction for your room's unique acoustics. It reproduces voices and other lead instruments with accuracy, making it suitable for many genres. The bass and treble levels are adjustable, too. It doesn't reproduce much low-bass, though, so bass-heavy genres like EDM and hip-hop lack some thump and rumble. With its stereo sound and impressive directivity, you get a wide and immersive soundstage. Also, if you want to listen to Dolby Atmos Music on your eligible music streaming service, this is one of the few speakers we've tested that support it.
- Room correction tool.
- Bass and treble adjustments.
- Some compression at max volume.
Not much low bass.
The Sonos Era 300 is fair for watching videos and movies on its own. You can wirelessly stream audio to the speaker over Bluetooth, Wi-Fi, and Apple AirPlay 2, or purchase a separate Line-In Adapter from Sonos to connect a computer or other audio sources. Dialogue is clearly reproduced, and its impressive directivity helps your audio sound wide and immersive. However, it doesn't reproduce much low bass, so action-packed scenes lack deep rumble. If you purchase two of these speakers, you can pair them with a soundbar like the Sonos Arc Ultra, along with a Sub 4 to complete the Sonos Ultimate Immersive Set with Arc Ultra, for a more complete home cinema experience.
- Bass and treble adjustments.
- Compatible with other Sonos devices.
- Some compression at max volume.
Not much low bass.
The Sonos Era 300 is fair for podcasts. Dialogue is reproduced with clarity right out of the box, meaning you can follow along with your favorite shows easily. If you own other Sonos products, you can connect them in the S2 app to spread sound throughout your home or to move a podcast from one room to another as you move around the house. The speaker gets loud enough for an average-sized living room but doesn't fill up larger spaces, so you'll want to keep it relatively close by as you listen.
- Room correction tool.
- Compatible with other Sonos devices.
- Some compression at max volume.
- Larger design.
The Sonos Era 300 is an excellent choice for voice assistants. Built-in Alexa lets you control the speaker hands-free, and she has no trouble hearing your commands, even if you're further away or in a noisy environment. The microphone mute button on the back of the speaker gives you the option for privacy. Plus, additional voice assistant features are designed to work with certain music streaming platforms, like Siri and Apple Music through the Apple Home app, and Sonos Voice Controller with services like Sonos Radio.
- Room correction tool.
- Compatible with other Sonos devices.
- Some compression at max volume.
As a wired-only speaker, this device isn't intended for outdoor use.

Differences Between Sizes And Variants
The Sonos Era 300 is available in both 'Black' and 'White' color variants. We tested the 'Black' variant, and you can see the label for our model here. Since the only obvious difference between the models is their color, we expect both the 'Black' and 'White' variants to perform similarly. You can also purchase the Sonos Ultimate Immersive Set with Arc Ultra, a soundbar setup that includes two Era 300 speaekers as satellites.
If you come across another version of this speaker, please let us know in the forums, and we'll update our review.

The Sonos Era 300 is a newer model from the manufacturer and is more versatile than the Sonos Five. Notably, it offers Bluetooth connectivity and built-in voice assistant support, whereas the Five only supports voice assistants via third-party devices. The Era 300 supports Dolby Atmos for compatible music and videos streamed through a paired soundbar, unlike the Five.
The Sonos Era 300 is better than the Sonos Era 100. The 300 is a larger speaker with additional features, including Dolby Atmos support, which is great if you want to listen to Dolby Atmos music. On a smaller note, its voice assistant performs a touch better in noisy environments, which may or may not be important to you.
The Sonos Era 300 and the Sonos Move 2 are designed for different usages. The Era 300 is a wired-only home speaker, so it's not as portable as the Move 2 and isn't rated for dust or water resistance. Still, it has Dolby Atmos support, which the Move 2 lacks. If you want a battery-powered speaker to bring outdoors, though, the Move 2 is a better bet.
The Sonos Era 300 and the JBL Authentics 500 are both premium home speakers with built-in voice assistant support. Some listeners may prefer the JBL's retro design. But if you already own Sonos products, you can integrate them with the Sonos Era, which is a nice feature.
