Short answer: the Ruimatech RM-10. It ranks #29 of 113 boombox speakers by sound quality, rated 3.8/5, at $159.99; the Soundcore Boom 2 Plus ranks #39, rated 3.6/5, and costs $169.99, which makes this an easy call rather than a real tradeoff.
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. Watch for: It is tuned bass boosted, much like the JBL Boombox 3.
The Soundcore Boom 2 Plus is the longer-running option. A fairly light stereo boombox, easy to carry to the beach or park. It is rated for 20 hours of battery against 14 for the Ruimatech RM-10. The tradeoff: Warm tuning meaning a rolled off treble and some upper bass boost.
Buy the Ruimatech RM-10. It is rated higher for sound quality than the Soundcore Boom 2 Plus and costs less, which makes it the one to get unless you need something the other one does better.
