Short answer: the JBL Partybox Encore Essential 2. It ranks #6 of 89 boombox speakers by sound quality, rated 4.3/5, at $219. The W-King H330 ranks #31, rated 3.8/5, at $119.99, $99.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
What the JBL Partybox Encore Essential 2 does well: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. The tradeoff: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
What the W-King H330 does well: 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 JBL Partybox Encore Essential 2. It is rated higher for sound quality, and the $99.01 saving on the W-King H330 is not enough to make up the difference.

The Two Speakers In Full
JBL Partybox Encore Essential 2: $219.00 Amazon B&H Photo Video eBay
Older model: the JBL Partybox Encore Essential (ranked lower, rated 4.2/5).
Pros: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. Independent testing finds a balanced midrange, genuinely punchy low bass and enough output for a backyard gathering; its dome tweeters also improve the earlier Encore’s high-frequency behavior.
Cons: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume. Bluetooth latency can cause lip-sync issues, its IPX4 rating only covers splashes, and it omits the wireless microphones bundled with the non-Essential Encore 2.

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.
