Sonos Era 300 Spatial Audio Speaker

The Sonos Era 300 is a mains-powered wireless speaker designed for spatial audio playback and multi-room home listening. According to Sonos Australia, the hardware incorporates six Class-D digital amplifiers driving two woofers and four tweeters, including side-firing and upward-firing drivers specifically arranged to project Dolby Atmos music tracks. It connects to home networks using dual-band Wi-Fi 6 or pairs directly to devices using Bluetooth 5.3. For control, the unit features capacitive top touch controls, integration with the Sonos mobile app, and built-in Amazon Alexa voice control. A physical microphone switch sits on the rear housing, allowing you to cut power to the far-field microphone array completely.

Who it suits

The Era 300 suits households that prioritise spatial audio formats or already use the Sonos platform for synchronised multi-room sound. It works well for Apple ecosystem users who stream via AirPlay 2, as well as smart homes structured around Amazon Alexa, Samsung SmartThings, or Home Assistant. Sonos states that Trueplay acoustic tuning operates on both iOS and Android, which benefits users across mobile operating systems trying to calibrate the speaker to an enclosed room or living space. Per Sonos, the moisture-resistant polycarbonate housing also makes it suitable for placement in kitchens. Conversely, households that rely on Google Assistant for voice commands should look elsewhere, as Google Assistant is not supported on this model. Anyone requiring portable battery power or standard, out-of-the-box 3.5 mm aux inputs without buying additional adapters should also skip this speaker.

Australian notes

Retail models sold in Australia (model numbers E30G1AU1BLK for black and E30G1AU1WHT for white) feature an internal universal power supply rated for 100–240V at 50/60 Hz. The box includes a detachable standard figure-8 AC mains power cable matching Australian wall outlets. For network integration, the speaker connects to both 2.4 GHz and 5 GHz bands across 802.11a/b/g/n/ac/ax protocols, ensuring compatibility with standard Australian home NBN routers. The speaker comes with a 1-year standard manufacturer warranty, which sits alongside consumer guarantees provided under Australian Consumer Law. Operating the speaker does not require a paid subscription, though streaming Dolby Atmos spatial audio tracks relies on supported external music streaming subscriptions.
