Smart speaker pioneer Sonos today announced the stunning Era 300 and Eera 100 next-generation smart speakers.

“In an age of constant background noise, quality listening matters more than ever,” Sonos CEO Patrick Spence says. “Our vision is to make listening an experience that is charged with feeling, and help our customers feel joy and vitality through their favorite music and audio content. The Era family is the next generation of smart speakers, epitomizing our commitment to sound innovation, responsible design, and a deep connection to the creator community.”

The Era 300 replaces the Sonos Five as the company’s flagship product, and it combines a stunning new design with Dolby Atmos functionality for immersive sound in one- or two-speaker configurations. It also offers USB-C line-in and Bluetooth capabilities. The Era 300 arrives on March 28 and retails for $449.

The smaller Era 100 replaces the Sonos One and One SL, though the firm is keeping those other products in the market for now. It has a more familiar design but features next-generation acoustics and USB-C line-in and Bluetooth capabilities. The Era 100 also arrives on March 28 and retails for $249.

Both Era smart speakers are more future-proof than most previous Sonos products thanks to line-in and Bluetooth compatibility. Both are most sustainable thanks to their use of post-consumer recycled (PCR) plastic and 100 percent sustainably sourced paper packaging. And both are more easily repairable, with standard screws and less adhesive use.
