Short answer: the JBL Partybox Encore Essential 2. It ranks #6 of 89 boombox speakers by sound quality, rated 4.3/5, at $219. The Ruimatech RM-10 ranks #28, rated 3.8/5, at $159.99, $59.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the JBL Partybox Encore Essential 2: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. The catch: 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.
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. 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 $59.01 you would save on the Ruimatech RM-10 does not close the gap.

The Two Speakers In Full
JBL Partybox Encore Essential 2: $219.00 Amazon B&H Photo Video eBay
Older model: the JBL Partybox Encore Essential (ranked lower, rated 4.2/5).
Pros: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. Independent testing finds a balanced midrange, genuinely punchy low bass and enough output for a backyard gathering; its dome tweeters also improve the earlier Encore’s high-frequency behavior.
Cons: 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. Bluetooth latency can cause lip-sync issues, its IPX4 rating only covers splashes, and it omits the wireless microphones bundled with the non-Essential Encore 2.

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.
