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 $217.99, $3,782.01 cheaper.
The case for the B&O Beosound 2: A beautifully made luxury Wi-Fi speaker that fills a room in every direction, with Chromecast, AirPlay, optical input and 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: A compact Wi-Fi smart speaker with stereo from two angled tweeters, Trueplay room tuning, Alexa and Sonos multiroom. 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.
