Short answer: the Harman Kardon Onyx Studio 5. It ranks #19 of 73 boombox speakers by sound quality at $499.99; the B&O Beolit 20 ranks #31 and costs $649.99, so there is not much of a tradeoff to weigh.
The case for the Harman Kardon Onyx Studio 5: Elegant circular design with carrying handle. Bass-heavy with balanced mids and highs. Watch for: Warm sound with boosted bass. 8 hour battery at medium volume. Not at loud as others.
What the B&O Beolit 20 gets right: Wireless phone charging. The tradeoff: Warm sound. Rolled off treble. Bass not as deep as the Onyx Studio 7.
Buy the Harman Kardon Onyx Studio 5. It ranks higher for sound quality than the B&O Beolit 20 and costs less, so there is no real case for the other one.
If water resistance matters to you, the Harman Kardon Onyx Studio 5 at IPX7 (brief submersion) holds up far better than the B&O Beolit 20 at IPX4 (splashing).
