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, including their soundbars. 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 good for music. Like most premium speakers on the market, this device has a room correction tool designed to automatically optimize audio reproduction based on the unique acoustics of your room. It reproduces voices and other lead instruments with accuracy, making it suitable for many genres. The bass and treble levels are adjustable, too. There's a little less low bass than with the Sonos Five, but you still feel some rumble in the mix with bass-heavy genres like EDM. With its stereo sound, you get a wide and immersive soundstage. Also, if you want to listen to Dolby Atmos Music on your eligible music streaming service, it's one of the few speakers we've tested to support this technology.
- Room correction tool.
- Bass and treble adjustments.
- Loudness tool to improve bass reproduction at lower volumes.
- Some compression at max volume.
The Sonos Era 300 is decent 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 there's some rumble in the low bass for more action-packed scenes. If you purchase two of these speakers, you can pair them with compatible Sonos soundbars for surround sound.
- Bass and treble adjustments.
- Compatible with other Sonos devices.
- Some compression at max volume.
- Touch less low bass than the Sonos Five.
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 the podcast from one room to the next 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 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.

Notably, it offers Bluetooth connectivity as well as built-in voice assistant support, whereas the Five only supports voice assistants through third-party devices. The Era 300 has a better dynamics performance. Also, it 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 with different use cases in mind. 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 a better low-frequency extension and 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 is better than the Sonos One Gen 2/One SL. The Era 300 is a newer release that offers more premium features, including Bluetooth connectivity and Dolby Atmos capabilities. It's especially handy for those who want to listen to compatible Dolby Atmos Music or even pair up the speaker with a compatible soundbar to watch Dolby Atmos content. It's a stereo speaker, unlike the One Gen 2, which downmixes stereo content into mono to play it. Plus, the Era 300 gets louder.
