Short answer: the Harman Kardon Onyx Studio 6. It ranks #11 of 73 boombox speakers by sound quality at $130; the W-King H10 ranks #52 and costs $215, which makes this an easy call rather than a real tradeoff.
What the Harman Kardon Onyx Studio 6 offers: Warm sound with boosted bass. Oluv liked it slightly better than the newer Onyx 7. Watch for: 8 hour battery at medium volume. Not at loud as others.
What the W-King H10 offers: Comes with wireless microphone. Loud. Watch for: Not very deep bass. Boosted upper bass. Upper midrange dips. Distorts above medium volumes. No water rating.
Buy the Harman Kardon Onyx Studio 6. It ranks higher for sound quality than the W-King H10 and costs less, so the other one has nothing left to offer.
Battery life favors the W-King H10: rated for 24 hours against 8 hours for the Harman Kardon Onyx Studio 6.
