Short answer: the Zealot ZE21 for better sound quality, the W-King X10 for the lower price. The Zealot ZE21 ranks #15 of 73 boombox speakers at $247.41. The W-King X10 ranks #62 at $80, $167.41 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 X10 offers: 70W RMS output with 120W peak power, exceptional 42-hour battery life, power bank function, IPX6 waterproof, 106dB max volume, EQ with indoor/outdoor modes, dual woofers with tweeters and passive radiators, Bluetooth 5.0 with 100ft range, MicroSD and USB playback, AUX input, TWS stereo pairing Watch for: Heavily rolled off treble, less bass than the top ranked.
Buy the Zealot ZE21 if sound quality matters more than the price. Buy the W-King X10 if the price matters more than sound quality.
If sound quality matters at all to you, skip the W-King X10. It ranks near the bottom of the 73 boombox speakers, so look higher up the list instead.
