Short answer: the Ruimatech RM-10. Both are rated 3.8/5 for sound quality (#28 and #26 of 89 boombox speakers), and the Ruimatech RM-10 costs $159.99 against $349.95 for the JBL Boombox 3, with sound quality a draw, the lower price decides it.
The case for the JBL Boombox 3: IP67 rated. The tradeoff: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700Hz, not quite as good mids and treble as the Blast.
What the Ruimatech RM-10 does well: 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.
Buy the Ruimatech RM-10. Both are rated the same for sound quality, and it costs $189.96 less than the JBL Boombox 3.

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.
