B&O Beosound Level vs Sonos Era 300

These are not really the same size class, and that is the honest framing here. The B&O Beosound Level ranks #61 of 78 large speakers by sound quality at $2250; the Sonos Era 300 ranks #4 of 5 powered desktop speakers by sound quality at $499.

The case for the B&O Beosound Level: Premium Scandinavian design with elegant domestic sculpture aesthetic. The tradeoff: Not very deep bass, peaks in midrange.

The case for 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 tradeoff: RTINGS’ one listed con is some compression at max volume.

Buy the B&O Beosound Level ($2250) for a large speaker; the Sonos Era 300 ($499) suits a powered desktop speaker instead.

Skip the B&O Beosound Level if sound quality matters to you. It ranks near the bottom of the 78 large speakers.

If water resistance matters to you, the B&O Beosound Level at IP54 (splashing) holds up far better than the Sonos Era 300 at no water resistance.

Sonos Era 300: $499.00 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.
