Short answer: the W-King X20S. It ranks #29 of 89 boombox speakers by sound quality, rated 3.8/5, at $150.99; the EcoXGear Defender ranks #72, rated 2.5/5, and costs $299.99, which makes this an easy call rather than a real tradeoff.
What the W-King X20S does well: 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 EcoXGear Defender does well: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. The catch: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited.
Buy the W-King X20S. It is rated higher for sound quality than the EcoXGear Defender and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.

EcoXGear Defender: $299.99 Amazon eBay
Pros: A rugged 4.54kg outdoor speaker with IP67 protection, a floating design, a flashlight, bottle opener, aux input, USB-C power-bank output and claimed 25-hour battery life. Independent testing found it gets very loud for its size, while its three ecoEQ presets let you choose a bass-heavy default, a more balanced indoor mode or a brighter outdoor mode.
Cons: Its single front-facing driver layout has narrow dispersion: clarity and detail drop noticeably when you move off-axis, and the soundstage is limited. The default setting can be over-bassy at lower volumes, while there is no app, precise EQ, battery indicator or multi-speaker party mode. Bass does not reach as deep as competitors.
