The Sonos Era series gives a new dimension to your surround sound setup. You can use the new Sonos WiFi speaker as a rear speaker with your soundbar. You can also use the speaker as a stand-alone speaker for beautiful and clear sound. Thanks to this, you can stream music in high quality which fills the room. The Sonos Era 300 has Dolby Atmos. Thanks to this, the sound comes from the front, but also reflects against the side and the ceiling. This provides spatial audio. The Sonos Era 100 is the successor of the One and ensures an even more detailed sound experience. With a speaker of the Sonos Era series, you're in the middle of your favorite movie or series.
