Short answer: the JBL Partybox Encore Essential. It ranks #8 of 113 boombox speakers by sound quality, rated 4.2/5, at $299.95. The Ruimatech RM-10 ranks #29, rated 3.8/5, at $159.99, $139.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL Partybox Encore Essential is the better-sounding pick. A compact stereo party speaker with great sound, strong output, and splash resistance for backyard parties.
The Ruimatech RM-10 is the longer-running, tougher pick. An affordable three-way boombox with clear sound that holds up at full volume, water resistance and fast charging. It is rated for 14 hours of battery against 6 for the JBL Partybox Encore Essential. It is rated IPX6 against IPX4 for the JBL Partybox Encore Essential. The catch: It is tuned bass boosted, much like the JBL Boombox 3.
Buy the JBL Partybox Encore Essential. It is rated higher for sound quality, and the $139.96 saving on the Ruimatech RM-10 is not enough to make up the difference.
