Short answer: the B&O Beosound 2 on measured sound quality, the Sonos Era 100 on price. The B&O Beosound 2 ranks #7 of 10 powered desktop speakers, rated 3.7/5, at $4,000. The Sonos Era 100 ranks #16, rated 3.6/5, at $219, $3,781 cheaper.
The case for the B&O Beosound 2: A beautifully made, compact Wi-Fi speaker with omnidirectional playback, Chromecast, AirPlay, Bluetooth with AAC/aptX, optical and aux inputs, app EQ, voice control and Beolink multiroom. It supports aptX Bluetooth, which the Sonos Era 100 lacks. It keeps a wired aux input, which the Sonos Era 100 lacks. The tradeoff: Its bass-forward balance can recess the mids, and its 94dB maximum level is modest for a speaker intended to fill larger spaces.
Why pick 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 tradeoff: 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 2 when sound quality outweighs the price for you, and the Sonos Era 100 when the price outweighs sound quality instead.

The Two Speakers In Full
B&O Beosound 2: $4,000.00 each Amazon eBay
Same family: the B&O Beosound 1 (smaller model, rated 3.5/5).
Pros: A beautifully made, compact Wi-Fi speaker with omnidirectional playback, Chromecast, AirPlay, Bluetooth with AAC/aptX, optical and aux inputs, app EQ, voice control and Beolink multiroom. Reviews praise its even scaling at low volume, spacious room-filling presentation and convincing bass for a single 4.1kg enclosure. Measured bass extension of ~45Hz (-10dB).
Cons: Its bass-forward balance can recess the mids, and its 94dB maximum level is modest for a speaker intended to fill larger spaces. There is no battery or water rating, so this is a mains-powered indoor product; its luxury design and streaming feature set matter more than outright value or neutral hi-fi accuracy.

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.
