Short answer: the W-King H330, if you are buying new. The Harman Kardon Onyx Studio 8 ranks higher than it (#12 vs #31 of 89 boombox speakers, 4.1/5 vs 3.8/5) but is discontinued, so only consider it used; the W-King H330 is still sold new at $119.99.
The case for the Harman Kardon Onyx Studio 8: At 3.3 kg, Harman Kardon Onyx Studio 8 combines a 120mm woofer and 2x 20mm tweeters with Bluetooth and aux. The tradeoff: Bass is limited by its 35Hz specification.
Why pick 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 W-King H330, since the Harman Kardon Onyx Studio 8 is discontinued and only worth hunting down used.

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.
