Sonos has finally added Bluetooth to the list of home-based connectivity options. Having allowed the tech into its portable Move and Roam speakers, quite why the company has been so resistant to rolling it out for “home” models remains a mystery, but we should probably just be grateful it’s finally included. The standard of Bluetooth, though, and the codecs the Era 300 is compatible with, is a secret because … well, because Sonos. And the Era 300 becomes the only Sonos speaker except for the Five to feature an analogue line in—although you will need a specific Sonos line-in adapter which, inevitably, has a cost attached.

The company has refreshed its physical user interface for its new speakers. There’s a volume slider on the speaker cabinet now, along with Play/Pause and Repeat controls, and there’s also a control to mute the integrated mics. (The Era 300 is compatible with Amazon Alexa voice control and the company’s own Sonos Voice Control.) And a species of Sonos’ admirable Trueplay calibration software is now available for Android users—until now it was purely for the iOS crowd.

As well as being a stand-alone speaker, two Era 300s can be used as rear speakers in a Sonos-centric home-cinema system. Used in conjunction with the Arc soundbar, 7.1.4-channel audio is possible, while 5.1.4 can be achieved when using a Beam Gen 2.

The new $249 (£249) Era 100 speaker, meanwhile,  can also be used as a rear speaker (or two) in a home cinema set-up and, while Sonos suggests it’s a stereo speaker all by itself, two can be paired for a larger sound. But while it includes some of the advancements showcased in the Era 300 (Bluetooth connectivity, Trueplay for Android users), it’s fundamentally an update of the profoundly successful Sonos One speaker. A “remaster” is how Sonos describes it. 

Era 100 features a pair of angled tweeters for greater sonic reach, and a mid/bass driver that’s 25 percent larger than the item in the Sonos One. This means three blocks of Class D amplification, of course—but if you’re expecting any technical details, any at all, you’re out of luck.

Like the rest of the Sonos range, the Era 100 and Era 300 will be available in black or white finishes. Both are on sale from March 28. And you’ll be able to read reviews of both of these speakers here soon.
