Short answer: the Monster Rockin’ Roller 270, though neither ranks well in its class. It ranks #70 of 76 boombox speakers at $249; the Turtlebox Gen 2 ranks #72 at $400, so there is little real tradeoff here. Both are rated below 3.0/5 among the 76 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
The Turtlebox Gen 2’s own review is unusually blunt. Its cons note it sounds basically identical to the original and the Gen 3, since each generation mainly added features rather than sound quality, and that its actual output is closer to 50W despite marketing claims, with barely any bass and rattling at higher volume. Its pros are limited to being waterproof and crushproof with a 25-hour battery and USB-C charging.
The Monster Rockin’ Roller 270 leans hard into practical extras. It offers a 100-hour battery life, four times the Turtlebox’s runtime, true stereo output across 270 degrees of coverage, wheels and an integrated handle for moving it around, and a Qi wireless charging pad for your phone. The tradeoffs are real: bass isn’t as deep as competitors and is less neutral than ION speakers, and at 28.7 lbs it is nearly three times the Turtlebox’s weight.
If water resistance matters, the tables turn: the Turtlebox Gen 2 is IP67 rated for brief submersion, while the Monster is only IPX4, rated for splashing.
Buy the Monster Rockin’ Roller 270 for the dramatically longer battery life, true stereo, and mobility features at a lower price, and accept the extra weight and shallower bass.
Buy the Turtlebox Gen 2 only if you specifically need real water submersion resistance that the Monster’s splash-only rating can’t match, and can find it at a discount given its age.

Turtlebox Gen 2: $400 Discontinued eBay
Newer model: the Turtlebox Gen 3, rated 2.1/5.
Pros: Waterproof and crushproof, loud with punchy bass. 25 hour battery life (6 hours at full volume; 3 hour charge time). USB-C charging and USB-C output charges other devices, an upgrade over the original’s AC power brick. Pairs with a second unit for stereo. Measured bass extension of ~65Hz (-10dB).
Cons: Sounds basically identical to the original and the Gen 3: each generation mainly added features, not sound quality. They pretty much lie about all their specs and sound horrible in all youtube sound samples. Only 50w (from their indigogo page), will never hit 120db at a reasonable measuring distance. Putting your db meter right against the speaker doesn’t count, 1 meter distance is the standard. Barely any bass. Rattles at high volume. Looking at it, it appears to be a generic car 2-way 6x9 speaker in a plastic box. Discontinued.
