Short answer: the Ruimatech RM-10. It ranks #28 of 89 boombox speakers by sound quality, rated 3.8/5, at $159.99; the EcoXGear Defender ranks #72, rated 2.5/5, and costs $299.99, so there is little reason to consider the other one.
The case for the Ruimatech RM-10: A three-way boombox (80W woofer, two 20W midranges, two 10W tweeters and dual passive radiators, 140W RMS) with a hi-fi leaning clarity, highs that don’t get screechy at max volume, and bass that holds on at full volume. The tradeoff: It is tuned bass boosted, much like the JBL Boombox 3.
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 Ruimatech RM-10. It is rated higher for sound quality than the EcoXGear Defender and costs less, which makes it the one to get unless you need something the other one does better.

Ruimatech RM-10: $159.99 Amazon eBay
Pros: A three-way boombox (80W woofer, two 20W midranges, two 10W tweeters and dual passive radiators, 140W RMS) with a hi-fi leaning clarity, highs that don’t get screechy at max volume, and bass that holds on at full volume. Side by side it beat the W-King X20S and X20 and sounded as good as the Tribit Stormbox Blast 2, especially at higher volume. IPX6, a claimed 14 hours, a USB-C power bank, 30W fast charging and stereo pairing.
Cons: It is tuned bass boosted, much like the JBL Boombox 3. There is no app or custom EQ and no shoulder strap, and the design is plain.

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.
