Sonos Era 300 Review: Spatial Audio Excellence

Sonos packages the Era 300 with the care its $449 price demands. Opening the box reveals a speaker with a distinctive design unlike any competitor - the organic, sculptural shape is immediately striking and polarizing. Our white test unit has a matte finish that resists fingerprints well, while the black option offers a more understated appearance. The box contains only the speaker and a power cable, reflecting Sonos's environmental commitment. Setup requires the Sonos app, which guides you through WiFi connection, account setup, and the TruePlay room tuning that optimizes sound for your specific room using your iPhone's microphone. The speaker is surprisingly large in person - photos don't convey its substantial footprint. Placement matters significantly for spatial audio performance; Sonos recommends positioning away from walls with the front facing the listening area.

The Era 300 is designed specifically for Dolby Atmos Music, the spatial audio format that adds height and dimensionality to compatible recordings. Six amplified drivers - including upward-firing and side-firing units - create a sound field that surrounds and envelops the listener in ways traditional stereo cannot achieve. When playing Atmos content from Apple Music or Amazon Music HD, the experience is genuinely immersive, with sounds appearing to come from various positions around and above you. Standard stereo content is also exceptional, with Sonos's processing creating a wide, detailed soundstage. Bluetooth connectivity, absent from previous Sonos speakers, enables quick connection from any device without WiFi setup. Voice control through Amazon Alexa or Sonos Voice Control is available for hands-free operation. The Sonos app provides extensive control over EQ, grouping with other Sonos speakers, and management of music services.

Our listening tests confirmed the Era 300 as the best speaker for Dolby Atmos Music playback. With properly mastered Atmos tracks from Apple Music, the spatial experience is remarkable - instruments occupy distinct positions in 3D space, vocals feel present and centered, and ambient sounds appear to come from the sides and above. The effect is subtle with some tracks and dramatic with others, depending on the quality of the Atmos mix. TruePlay room tuning made a noticeable improvement in our test room, tightening bass and improving clarity. Standard stereo playback was also excellent, with the Era 300 producing a wider soundstage than traditional single-speaker solutions. Bass extension was impressive for the speaker's size, though not matching dedicated subwoofer performance. WiFi streaming worked reliably throughout our testing, with no dropouts or sync issues. Bluetooth connection was quick and stable. Voice control via Alexa responded accurately, though Sonos Voice Control's more limited capabilities became apparent for complex requests.
