Sonos Era 300: $499.00 each Amazon eBay
Pros: RTINGS calls it an excellent choice for voice assistants: built-in Alexa has no trouble hearing commands from a distance or in a noisy room, with a mic mute button on the back. Six drivers, one forward-firing tweeter, two side-firing tweeters, one upward-firing tweeter, and two angled woofers, each with its own Class D amp, give real stereo separation plus Dolby Atmos spatial audio on supported content. Trueplay room correction (now including a quicker Android tuning option) is a genuine strength, and it pairs with Sonos soundbars like the Arc Ultra for a home theater setup.
Cons: RTINGS’ one listed con is some compression at max volume. Out of the box the tuning leans bass-heavy enough that vocals can get shrouded in the mix on some tracks, though Trueplay largely corrects this. There’s no Google Assistant, no battery, and at $499 it’s the most expensive speaker in this ecosystem comparison.
