Short answer: the Zealot ZE21 if sound quality matters most, the W-King T11 if price matters most. The Zealot ZE21 ranks #15 of 73 boombox speakers at $247.41. The W-King T11 ranks #35 at $150, $97.41 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 T11 offers: 100W RMS output with 240W peak power, 112dB max volume, IPX6 waterproof, 10-hour battery life, power bank function, dual 5.25-inch woofers with tweeters and passive radiators, EQ with multiple modes, microphone and karaoke input, MicroSD and USB playback, TWS stereo pairing Watch for: Almost as deep of bass as the top ranked ones. A little hollow sounding. Wall wart charger.
Buy the Zealot ZE21 when sound quality outweighs the price for you, and the W-King T11 when the price outweighs sound quality instead.
There is a real battery-life gap here: the Zealot ZE21 is rated for 40 hours, the W-King T11 only 10 hours.
