Short answer: the Zealot S89 on measured sound quality, the W-King H330 on price. The Zealot S89 ranks #19 of 89 boombox speakers, rated 4.0/5, at $259.99. The W-King H330 ranks #31, rated 3.8/5, at $119.99, $140 cheaper.
The case for the Zealot S89: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. The catch: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
The case for the W-King H330: In Jagist’s side by side tests it was picked over the JBL Xtreme 5, came very close to the Harman Kardon Go + Play 3 with cleaner vocals, and sounded clearer and more balanced than the Tronsmart Fiitune X30. The catch: It isn’t very loud, and the W-King X20s plays louder with punchier bass.
Buy the Zealot S89 when sound quality outweighs the price for you, and the W-King H330 when the price outweighs sound quality instead.

Zealot S89: $259.99 Amazon AliExpress eBay
Pros: A 7.3kg boombox with a claimed 36Hz bass extension, 40-hour battery life, IPX6 protection, USB-C charging, aux, USB and microSD playback, TWS and multi-speaker PartyAdd. Listener comparisons find it capable of very high output and substantial bass for outdoor use. A great value for its bass, battery life and maximum volume. Measured bass extension of 36Hz (-10dB).
Cons: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers. The heavy cabinet and basic finish also make it less polished for daily portability, while its multiple EQ modes cannot substitute for a genuinely neutral tuning.

W-King H330: $119.99 Amazon eBay
Pros: In Jagist’s side by side tests it was picked over the JBL Xtreme 5, came very close to the Harman Kardon Go + Play 3 with cleaner vocals, and sounded clearer and more balanced than the Tronsmart Fiitune X30. A 5.5 inch woofer, two 2.5 inch tweeters and a down firing passive radiator give it deep, full bass for its size. A 50Wh battery with 45W USB-C fast charging (about 1.8 hours), Bluetooth 5.4, stereo pairing, a bass boost button, aux, TF card and USB playback, and ambient lighting.
Cons: It isn’t very loud, and the W-King X20s plays louder with punchier bass. Below about 20% volume its DSP makes the bass cut in and out. The factory tuning is V shaped: Storytripper HD found the vocals thin and dry next to the fuller JBL Authentics 300, and the mids can sound recessed. No handle, no app, no water resistance rating, and W-King rates the battery at about 9 hours at 70% volume.
