Short answer: the Ruimatech RM-10. Both are rated 3.8/5 for sound quality (#29 and #27 of 113 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 JBL Boombox 3 is the longer-running pick. A loud, fully waterproof boombox with a dedicated subwoofer, a 24 hour battery and power bank charging. It is rated for 24 hours of battery against 14 for the Ruimatech RM-10. The catch: 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: An affordable three-way boombox with clear sound that holds up at full volume, water resistance and fast charging. 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.
