Short answer: the W-King X20S. It ranks #29 of 89 boombox speakers by sound quality, rated 3.8/5, at $150.99. The Onn Medium Party Speaker Gen 2 ranks #58, rated 3.1/5, at $90, $60.99 cheaper, which does not close the gap in sound quality.
Why pick the W-King X20S: Clearer and smoother than the larger W-King X20 at about half its size and weight, and in side by side tests it held its own against the Harman Kardon Go + Play 3, with nicer, more exposed mids and more volume. The tradeoff: Less bass and depth than the X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass.
What the Onn Medium Party Speaker Gen 2 does well: Under $100 with LED lights synced to music. The catch: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass.
Buy the W-King X20S. It is rated higher for sound quality, and the $60.99 saving on the Onn Medium Party Speaker Gen 2 is not enough to make up the difference.

W-King X20S: $150.99 AliExpress W-King eBay
Pros: Clearer and smoother than the larger W-King X20 at about half its size and weight, and in side by side tests it held its own against the Harman Kardon Go + Play 3, with nicer, more exposed mids and more volume. 140W RMS (180W peak), IPX7, Bluetooth 5.4, a built-in microphone, TF card, USB and aux playback, FM radio, a carry handle and a shoulder strap.
Cons: Less bass and depth than the X20 and about 3dB quieter, and at maximum volume its mids and highs start to drown out the bass. With a flat EQ the bass is cut off, so it needs the bass boost. The JBL PartyBox Encore Essential 2 sounded better in a direct comparison. Sold direct from W-King in the US.
