Sonos Era 300

If you want a **smart speaker** that does more than fill the room with background music, the Era 300 is aimed squarely at you. It’s for people who care about **wireless speaker** sound first, but still want **Wi‑Fi, Bluetooth, Alexa, AirPlay 2** and Sonos multi-room convenience in one unit. ## What makes it worth it Sonos built the Era 300 around spatial audio, with **six drivers** arranged to fire forward, sideways and upward. In practice, that gives it a much wider, more enveloping sound than a typical smart speaker, and reviewers consistently call it one of the strongest single-box options for **Dolby Atmos Music**. It also supports **line-in via the Sonos adapter**, which is handy if you still use a turntable or other analogue source. Trueplay tuning is another real advantage, because it adjusts the speaker to your room instead of forcing you to live with stock EQ. ## Where it falls short It is not cheap, and the shape is a little divisive. More importantly, the Era 300 is at its best when you play it loudly enough for its spatial tricks to open up; at low volume, it is less exciting than the price suggests. Buy it if you want the best-sounding spatial audio smart speaker for a living room or Sonos setup. Skip it if you mostly want a cheap Alexa speaker or something that disappears into the background.
