Short answer: the JBL Partybox Encore Essential 2. It ranks #6 of 113 boombox speakers by sound quality, rated 4.3/5, at $249.95. The Ruimatech RM-10 ranks #29, rated 3.8/5, at $159.99, $89.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL Partybox Encore Essential 2 is the better-sounding choice. A compact party speaker with balanced sound, punchy bass, mic and guitar inputs, and enough volume for a backyard party. The tradeoff: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
The Ruimatech RM-10 is the tougher option. An affordable three-way boombox with clear sound that holds up at full volume, water resistance and fast charging. It is rated IPX6 against IPX4 for the JBL Partybox Encore Essential 2. Watch for: It is tuned bass boosted, much like the JBL Boombox 3.
Buy the JBL Partybox Encore Essential 2. It is rated higher for sound quality, and the $89.96 you would save on the Ruimatech RM-10 does not close the gap.
