Table of Contents
If you’re looking for a bluetooth and WiFi connectable speaker that will produce rich and detailed sound, letting you appreciate your music on a whole new level, and also works well as a TV speaker, this Sonos Era 300 is a fantastic choice! The speaker combines a sophisticated six-driver acoustic design, Dolby Atmos, Trueplay room tuning, the aforementioned Wi-Fi and Bluetooth connectivity, plus AirPlay, and optional line-in connectivity to create one of Sonos’ most versatile home speakers. Its multidirectional architecture is particularly effective with spatial music and becomes considerably more powerful when two speakers are used as a stereo pair or as Dolby Atmos surrounds with a compatible Sonos soundbar. For listeners invested in spatial audio or the wider Sonos ecosystem, the Era 300 offers capabilities that extend well beyond those of a conventional wireless smart speaker. Pick it up now for 21% off the MSRP for a limited time!
The Era 300 is mains powered rather than battery operated, so it is fundamentally a stationary home speaker. At approximately 6.65 x 6.65 x 7.44 inches and around 4.47kg, it remains compact enough for shelves and furniture, but adequate clearance around the speaker is useful because its multidirectional acoustic design benefits from space to disperse sound.

What we like about this Sonos Era 300 Wireless Smart Speaker
Six-driver acoustic architecture
The Sonos Era 300 uses six strategically positioned drivers to distribute sound forward, sideways, and upward rather than concentrating everything directly in front of the speaker. This unconventional arrangement is central to its ability to create a much broader soundstage than its relatively compact enclosure would suggest, particularly when reproducing spatial audio.

Dolby Atmos Music
Dolby Atmos support allows compatible music to extend beyond conventional left and right stereo channels by incorporating spatial and height information. The Era 300’s upward- and side-directed acoustic output gives it the physical hardware required to reproduce these additional dimensions rather than relying entirely on virtualized processing.
Custom waveguides
Sonos uses custom waveguides to control how individual drivers disperse sound around the room. Directing acoustic energy toward the left, right, front, and ceiling allows reflected sound to contribute to the presentation, increasing the apparent width and height of the soundstage and making a single Era 300 sound considerably larger than its physical dimensions.
Trueplay room tuning
Trueplay tuning allows the speaker to account for its acoustic surroundings rather than operating with a fixed equalization profile. Walls, furniture, corners, hard surfaces, and room dimensions can substantially alter perceived bass and tonal balance, so room correction helps the Era 300 adapt its output to its actual placement.
Wi-Fi and Bluetooth connectivity
Unlike some earlier Sonos speakers that focused heavily on network streaming, the Era 300 combines Wi-Fi with conventional Bluetooth connectivity. Wi-Fi remains preferable for high-quality network playback and multi-room integration, while Bluetooth makes it considerably easier for visitors or devices outside the Sonos ecosystem to connect directly.
Optional line-in connectivity
A compatible Sonos Line-In Adapter allows an external analog source to be connected through the speaker’s USB-C interface. This creates possibilities for turntables with an appropriate phono stage and other conventional audio equipment, expanding the Era 300 beyond purely wireless streaming.
Stereo pairing
Two Era 300 speakers can be configured as a stereo pair, assigning dedicated left and right channels rather than asking one enclosure to create the entire stereo image. This substantially increases separation, scale, and positional precision for conventional stereo music while retaining the speakers’ spatial-audio capabilities.
Dolby Atmos home-theater expansion
A pair of Era 300 speakers can serve as surrounds with compatible Sonos soundbars such as Arc or Beam (Gen 2). Their side- and upward-firing output makes them particularly useful in this role because they can contribute lateral and overhead information to a Dolby Atmos soundtrack rather than functioning only as conventional rear speakers.
Who should consider this Sonos Era 300 deal?
The Sonos Era 300 is aimed at listeners who want a premium wireless speaker but place particular importance on spatial audio. Its six-driver arrangement and Dolby Atmos support distinguish it from simpler smart speakers designed primarily for background music and voice assistance.
It is particularly attractive to existing Sonos users. A single Era 300 can operate as a standalone music system, two can form a more expansive stereo pair, and a pair can also become sophisticated surround speakers within a compatible Sonos home-theater configuration.
Listeners using conventional stereo music can still benefit from its broad dispersion and room tuning, although buyers interested exclusively in traditional two-channel playback may not exploit everything that makes the Era 300 unusual. Its strongest case is as a flexible speaker that can move between music, spatial audio, multi-room playback, and home theater.
