Short answer: the Sony ULT Field 5. It ranks #44 of 82 large speakers by sound quality, rated 3.5/5, at $198; the B&O Beosound Level ranks #65, rated 2.8/5, and costs $2,250, which makes this an easy call rather than a real tradeoff.
Why pick the Sony ULT Field 5: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. The catch: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth.
Why pick the B&O Beosound Level: Premium Scandinavian design with elegant domestic sculpture aesthetic. Watch for: Not very deep bass, peaks in midrange.
Buy the Sony ULT Field 5. It is rated higher for sound quality than the B&O Beosound Level and costs less, so only choose the other one for a particular feature it does better.
If battery life is a priority, the Sony ULT Field 5 is rated for 25 hours versus 16 hours for the B&O Beosound Level.
There is a real gap in water resistance: the Sony ULT Field 5 at IP67 (brief submersion) against the B&O Beosound Level, which has IP54 (splashing).

The Two Speakers In Full
Sony ULT Field 5: $198 Amazon eBay
Older models: the Sony SRS-XB43 (rated 3.5/5) and the Sony SRS-XG300 (rated 3.1/5).
Pros: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. Reviews find it energetic and dynamic with substantial bass, enough volume for a yard, and two ULT modes that let bass-focused listeners choose a deeper or punchier presentation.
Cons: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth. Deep bass is less authoritative than the enclosure suggests, and the loud confirmation tone when pressing the ULT button is an unnecessary annoyance. Use the app EQ and audition it before buying for detail-focused music.
