These sit in different size classes, so this is not a straight ranking comparison. The B&O Beosound Level ranks #84 of 102 large speakers by sound quality at $2,250; the Sonos Era 100 ranks #16 of 24 powered desktop speakers by sound quality at $219.
The B&O Beosound Level is the battery-powered, tougher option. Premium Scandinavian design with elegant domestic sculpture aesthetic. Its battery is rated for 16 hours, while the Sonos Era 100 needs an outlet. It is rated IP54, while the Sonos Era 100 has no water resistance. It keeps a wired aux input, which the Sonos Era 100 lacks. Watch for: Not very deep bass, peaks in midrange.
The case for the Sonos Era 100: It links with other speakers (Sonos multi-room, AirPlay 2), which the B&O Beosound Level cannot. It has an adjustable EQ, which the B&O Beosound Level lacks. 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.
Buy the B&O Beosound Level at $2,250 for a large speaker, or the Sonos Era 100 at $219 for a powered desktop speaker instead.

Sonos Era 100: $219.00 each Amazon eBay
Same family: the Sonos Era 300 (larger model, rated 4/5).
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.
