Sonos Era 300 Dolby Atmos Bluetooth WiFi Smart Speaker

Spatial Audio Built Around Dolby Atmos Music

Sonos Era 300 E30G1US1 is a powered smart speaker designed specifically for spatial audio and Dolby Atmos Music. Its six-driver acoustic architecture directs sound forward, sideways, and upward to create a wider and more three-dimensional listening experience than a conventional single-box stereo speaker.

Use one Era 300 as a standalone spatial-audio speaker, pair two for dedicated stereo listening, or use a matching pair as immersive surrounds in a compatible Sonos home theater system.

Who Should Choose Sonos Era 300?

Choose Era 300 when spatial music and Dolby Atmos are priorities, or when you want premium rear surrounds for a compatible Sonos home theater system.

For conventional stereo-focused music listening without the same spatial-audio emphasis, another Sonos speaker may be a better fit. Era 300 is strongest when its directional drivers and height channel can be used as intended.

Six-Driver Spatial Audio Architecture

Six Class-D amplifiers power four tweeters and two woofers. The forward-facing tweeter creates a focused center image, two side-firing tweeters help create stereo separation, and an upward-firing tweeter reflects sound from the ceiling when reproducing compatible Dolby Atmos content.

Two woofers are angled left and right to extend low-frequency output and support stereo playback.

Dolby Atmos Music

Era 300 is designed to reproduce compatible spatial-audio music in Dolby Atmos. Spatial-audio availability depends on the streaming service, subscription, source content, and Sonos software support.

When compatible spatial music is playing, the upward-firing driver provides a physical height channel rather than relying only on virtualized processing.

Wi-Fi 6 and Bluetooth 5.3

Era 300 supports Wi-Fi 6 on compatible 2.4 GHz and 5 GHz networks for Sonos streaming, multi-room playback, spatial audio, AirPlay 2, and other connected features.

Bluetooth 5.3 allows direct playback from compatible phones, tablets, computers, and other Bluetooth sources.

Trueplay on iOS and Android

Trueplay measures the room acoustics and fine-tunes Era 300's EQ for its placement and listening environment. Sonos currently lists Trueplay compatibility with both iOS and Android devices.

Optional Line-In

Era 300 can accept an analog audio source such as a CD player or turntable through the USB-C port when used with the optional Sonos Line-In Adapter.

A turntable without a built-in phono preamp requires an external phono preamp before connecting to Era 300.

Line-in is disabled when Era 300 is configured as a surround speaker in a Sonos home theater system.

Optional Ethernet Connection

Era 300 does not have a built-in Ethernet jack. Wired networking requires the optional Sonos Combo Adapter connected through USB-C.

Voice Control and Microphone Privacy

Era 300 supports Sonos Voice Control and Amazon Alexa where available. Its far-field microphone array is also used for Trueplay tuning.

A physical microphone switch on the rear of the speaker disconnects power from the microphone hardware when additional privacy is desired.

Stereo Pairing

Two matching Era 300 speakers can be configured as a dedicated left/right stereo pair in the Sonos app for greater channel separation and a larger listening presentation.

Era 300 as Home Theater Surrounds

A matching pair of Era 300 speakers can serve as rear surrounds in compatible Sonos home theater systems. Their lateral and upward-firing drivers allow compatible Dolby Atmos soundtracks to add both surround and height information behind the listening position.

Sonos currently features Era 300 prominently with Arc Ultra in its premium Dolby Atmos surround systems.
