Short answer: the Marshall Woburn III for better sound quality, the Sonos Era 100 for the lower price. The Marshall Woburn III ranks #2 of 17 powered desktop speakers, rated 4.1/5, at $599.99. The Sonos Era 100 ranks #13, rated 3.6/5, at $219, $380.99 cheaper.
The case for the Sonos Era 100: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. The catch: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments.
The case for the Marshall Woburn III: At 7.44 kg, Marshall Woburn III combines 6” woofer, 2x 2” midranges, 2x 0.75” Dome tweeters with Bluetooth, HDMI, RCA, Aux. Watch for: Bass is limited by its ~45Hz specification.
Buy the Sonos Era 100 if the price is the priority over sound quality, or the Marshall Woburn III if sound quality is the priority over the price.

The Two Speakers In Full
Sonos Era 100: $219.00 each Amazon eBay
Pros: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. Alexa is built in with a far-field mic, and it ties into the wider Sonos S2 app ecosystem for multi-room audio.
Cons: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments. There’s no Google Assistant, the USB-C line-in needs a separately purchased adapter, and there’s no battery.
