Sonos Era 100 Black - Wireless, Alexa Enabled Smart Speaker $199.00 at Amazon $249.00 Save $50.00 Get Deal Get Deal $199.00 at Amazon $249.00 Save $50.00 The Sonos Era 100 came out in early 2023 and received an "excellent" review from PCMag for its ability to create stereo audio with a single device (it has a dual tweeter setup); its balanced audio; the useful companion app that allows you to adjust the EQ; its ability to connect with Bluetooth and wifi; Alexa and Sonos voice integration; and compatibility with most major music streaming services. As it is still a single speaker, the stereo effect won't match a true stereo setup, but it's a good approximation and an improvement over previous Sonos speakers. The real point of differentiation for the Sonos Era 100 (and most Sonos speakers, for that matter) is the ability to seamlessly group with other Sonos speakers that you own. Sonos makes it easy to handle multi-room pairing (lets you play your music in multiple Sonos speakers in different rooms) without needing to connect to your wifi over and over again.Back when the speaker first launched, it only supported Apple Music, Amazon Music, Deezer, and Pandorawith Spotify a notable omission. However, Spotify and other music services are now available. The Sonos voice assistant is still limited in capability, with no Google Assistant or Google Cast integration, and the speaker also doesn't support Dolby Atmos, which is disappointing for a device at this price level. Caveats aside, if you're looking for a stationary smart speaker with great audio that can easily connect with other Sonos speakers you own or might add in the future (they also work as rear speakers with a Sonos soundbar), the Sonos Era 100 is a great choiceespecially at 20% off.
