Short answer: the Zealot ZE51. It ranks #16 of 112 boombox speakers by sound quality, rated 4.1/5, at $235.33. The W-King X10 ranks #93, rated 2.3/5, at $80, $155.33 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Zealot ZE51 is the better-sounding choice. A big stereo boombox with clean, wide sound and low distortion at high volume for outdoor parties. Watch for: The Zealot ZE41 still wins on raw bass depth and price.
The W-King X10 is the longer-running, lighter option. A cheap, waterproof stereo boombox with a very long battery, loud output and a power bank for charging your phone. It is rated for 42 hours of battery against 4 for the Zealot ZE51. At 6.5 lbs (2.95 kg) it weighs much less than the Zealot ZE51 at 26 lbs (11.81 kg). Watch for: Heavily rolled off treble, less bass than the top ranked.
Buy the Zealot ZE51. It is rated higher for sound quality, and saving $155.33 with the W-King X10 does not make up for the sound-quality gap.
