Looking to upgrade your Sonos setup? The Sonos Era 300 (9/10, WIRED Recommends) is 20 percent off from Amazon, bringing it down to just 359 and tying its lowest-ever price. That's a great deal on our editors' favorite surround sound Sonos speaker, and it would make a perfect upgrade to your existing Sonos configuration or a place to start building your audio empire. The big draw here is spatial audio, which our team feels performs even better than Apple's Homepod (5/10, WIRED Review) when it comes to filling a room with sound. That's largely thanks to the array of drivers, including six speakers, four tweeters, and a pair of mid/bass drivers all packed into one vaguely robot-butt-shaped device.

The Era 300 is the second in Sonos's next-generation line of wifi hi-fis, packing six speakers into one curvaceous box capable of immersing listeners in quality sound. The speaker costs £449 ($449/A$749) and sits above the new £249 Era 100, competing directly with Apple's HomePod and other high-end speakers – premium audio at a premium price. But where the Era 100 is a compact bookshelf speaker, the Era 300 is a different animal. It needs to sit out in the open to allow it to project music outwards from its front, sides and top to fill the room with sound. The cinched-in design allows a series of speakers to fire up and out to the sides from the back half of the Era 300, projecting sound all around the listener for full stereo and new spatial audio surround sound.

No, of course you don't buy a speaker to look at it. But should your gaze fall upon your speaker while you're enjoying its sound, ideally the sight of it shouldn't make you wince. So it's just as well that Era 300, the latest Sonos wireless speaker and the company's first foray into spatial audio (except for its Dolby Atmos–enabled soundbars, of course), is such an impressive and accomplished performer--its physical appearance is easy to overlook. Unless you somehow find it in your field of vision unexpectedly, anyhow, in which case it never ceases to be startling. It's fair to say Sonos' ubiquity has, until now, been established as much on its utterly painless ownership experience as on the sound its products actually make.

If you pay attention to the music industry, you've probably heard about spatial audio. The promise is that music will envelop the user from all directions without needing a room full of speakers to achieve the effect. Apple has pushed it a lot in the last few years, in Apple Music, its line of AirPods headphones and the latest HomePod speaker. Amazon's streaming service also offers spatial audio, and its Echo Studio speaker can play back compatible tracks. Sonos has been paying attention, as well – its recent Arc and Beam soundbars support Dolby Atmos for movies, and now the company is releasing its first music speaker designed for spatial audio, the Era 300.
