Short answer: the JBL Partybox Encore Essential. It ranks #7 of 73 boombox speakers by sound quality at $299.95; the Harman Kardon Onyx Studio 5 ranks #19 and costs $499.99, so there is not much of a tradeoff to weigh.
What the JBL Partybox Encore Essential offers: A great sounding somewhat boosted bass party speaker. Set against that: Only 6 hours of battery at medium volume. Poor Water rating.
On the Harman Kardon Onyx Studio 5 side: 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.
Buy the JBL Partybox Encore Essential. It ranks higher for sound quality than the Harman Kardon Onyx Studio 5 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 JBL Partybox Encore Essential at IPX4 (splashing).
