Short answer: the Zealot ZE21 for better sound quality, the W-King H10 for the lower price. The Zealot ZE21 ranks #15 of 73 boombox speakers at $247.41. The W-King H10 ranks #52 at $215, $32.41 cheaper.
What the Zealot ZE21 offers: Great value for the bass performance, play time and max volume in the boombox class, though the Zealot ZE41 now beats it out. Watch for: A little rolled off up top and not that balanced through the rest of the range. Clarity isn’t as good as better speakers. Bass EQ is bloated and muddy sounding
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 Zealot ZE21 if sound quality matters more than the price. Buy the W-King H10 if the price matters more than sound quality.
Battery life favors the Zealot ZE21: rated for 40 hours against 24 hours for the W-King H10.
