Short answer: the Zealot ZE51. It ranks #16 of 113 boombox speakers by sound quality, rated 4.1/5, at $235.33. The W-King X10-1 ranks #90, rated 2.4/5, at $139.99, $95.34 cheaper, which does not close the gap in sound quality.
The Zealot ZE51 is the better-sounding option. A big stereo boombox with clean, wide sound and low distortion at high volume for outdoor parties. The tradeoff: The Zealot ZE41 still wins on raw bass depth and price.
The W-King X10-1 is the longer-running, lighter choice. An affordable stereo boombox with a very long battery, loud output, waterproofing and a power bank for charging phones. 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). The tradeoff: Rolled off treble, not much bass.
Buy the Zealot ZE51. It is rated higher for sound quality, and the $95.34 saving on the W-King X10-1 is not enough to make up the difference.
