Short answer: the Zealot ZE21 if sound quality matters most, the W-King X10-1 if price matters most. The Zealot ZE21 ranks #15 of 73 boombox speakers at $247.41. The W-King X10-1 ranks #61 at $143, $104.41 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 X10-1 offers: 70W RMS output with 120W peak power, 108dB max volume, exceptional 42-hour battery life with power bank, IPX6 waterproof, Bluetooth 5.0 with 100ft range, EQ with indoor/outdoor modes, dual subwoofers with tweeters and passive radiators, TWS stereo pairing, MicroSD and USB playback, AUX input, built-in microphone Watch for: Rolled off treble, not much bass.
Buy the Zealot ZE21 if sound quality is the priority over the price, or the W-King X10-1 if the price is the priority over sound quality.
If sound quality matters at all to you, skip the W-King X10-1. It ranks near the bottom of the 73 boombox speakers, so look higher up the list instead.
