Short answer: the W-King D9, though neither ranks well in its class. It ranks #91 of 105 large speakers by sound quality, rated 2.5/5, at $71.24; the Zealot S67 ranks #104, rated 2.0/5, at $70.94. Close enough in price that the sound-quality gap is the deciding factor. Both are rated below 3.0/5 among the 105 large speakers, so if sound quality matters, consider the Soundcore Rave Neo 2 instead, ranked #21 at $84.99.
The W-King D9 is the better-sounding, longer-running pick. A compact 4.4 lbs (2 kg) boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. It is rated for 40 hours of battery against 20 for the Zealot S67. The catch: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume.
Why pick the Zealot S67: It offers a lot of practical hardware for a 5.3 lbs (2.4 kg) budget speaker: IPX6 water resistance, USB-C charging, aux and microSD playback, speakerphone, a claimed 20-hour battery and TWS pairing for a second unit. The catch: Sound quality is the catch.
Buy the W-King D9. It is rated higher for sound quality, and the $0.30 you would save on the Zealot S67 does not close the gap.

W-King D9: $71.24 Amazon $71.24 eBay
Pros: A compact 2kg boombox with 60W RMS output, a claimed 106dB maximum level, a measured 47Hz -10dB bass point, IPX6 protection, power-bank output, USB-C charging, aux and microSD playback. Long-term owners praise its loud, punchy character and useful indoor/outdoor voicing for casual outdoor listening. Measured bass extension of 47Hz (-10dB).
Cons: Treble rolls off early, limiting air and fine detail, while owner reports note Bluetooth interference and some noise at maximum speaker volume. There is no app or adjustable EQ, and its bass does not reach as deep as larger rivals, so it is better suited to energetic background music than neutral listening.

Zealot S67: $70.94 AliExpress $70.94 eBay
Pros: It offers a lot of practical hardware for a 2.4kg budget speaker: IPX6 water resistance, USB-C charging, aux and microSD playback, speakerphone, a claimed 20-hour battery and TWS pairing for a second unit. The large enclosure and dual-driver/passive-radiator layout can provide useful party-level volume.
Cons: Sound quality is the catch. Independent reviewer comparisons report obvious distortion once volume rises past roughly halfway, little true deep bass, and a rolled-off, low-detail treble. There is no app or real EQ to correct that balance, so its long feature list does not make it a good pick for attentive music listening.
