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 Monster Rockin’ Roller 270 ranks #82, rated 2.1/5, and costs $249, so there is not much of a tradeoff to weigh.
What the JBL Partybox Encore Essential 2 does well: 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. Watch for: 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 case for the Monster Rockin’ Roller 270: 100 hour battery life. The tradeoff: Bass not as deep as competitors, less neutral than ION speakers.
Buy the JBL Partybox Encore Essential 2. It is rated higher for sound quality than the Monster Rockin’ Roller 270 and costs less, so only choose the other one for a particular feature it does better.

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.
