Short answer: the B&W Zeppelin Pro. It ranks #1 of 6 powered desktop speakers by sound quality, rated 4.4/5, at $639. The Sonos Era 300 ranks #4, rated 4.0/5, at $479.99, $159.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Sonos Era 300: 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. The catch: RTINGS’ one listed con is some compression at max volume.
What the B&W Zeppelin Pro does well: Titanium dome tweeters and an improved 24-bit DAC over the standard Zeppelin for slightly better high-frequency detail on hi-res streams. The tradeoff: Same price as the standard Zeppelin for a fairly modest tweeter/DAC upgrade.
Buy the B&W Zeppelin Pro. It is rated higher for sound quality, and the $159.01 saving on the Sonos Era 300 is not enough to make up the difference.

The Two Speakers In Full
Sonos Era 300: $479.99 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.

B&W Zeppelin Pro: $639.00 each Amazon eBay
Pros: Titanium dome tweeters and an improved 24-bit DAC over the standard Zeppelin for slightly better high-frequency detail on hi-res streams. Dynamic EQ DSP. Customizable downward-firing light. Same wide soundstage and deep bass extension as the standard Zeppelin.
Cons: Same price as the standard Zeppelin for a fairly modest tweeter/DAC upgrade. Nothing besides the lack of battery, lack of waterproofing, high cost and the Earfun Uboom X that’s so close to it in terms of sound quality for 7x less money. Basically an indoor only speaker. At this price point the Top Recommended Bookshelf Speakers are the better buy, with even better soundstage.
