Short answer: the Monster Bambox, though neither ranks well in its class. It ranks #74 of 98 boombox speakers by sound quality (rated 2.8/5) at $219 and is still sold new; the Turtlebox ranks #94 (rated 2.1/5) and is discontinued, so it is only an option used. The Turtlebox’s replacement, the Turtlebox Gen 3, is rated 2.1/5 at $430. Both are rated below 3.0/5 among the 98 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $199.99.
The Monster Bambox is the better-sounding, longer-running choice. Rated for up to 48 hours from a long life LiFePO4 battery, with IP67 waterproof and dustproof rugged housing, Auracast linking, a 30 watt USB-C charge out, a microphone input, app controlled EQ presets and 256 RGB lights. It is rated for 48 hours of battery against 25 for the Turtlebox. It links with other speakers (Auracast), which the Turtlebox cannot. It has an adjustable EQ, which the Turtlebox lacks. The catch: No measurements or reviews, so its rating is estimated, and the 300 watt figure is peak power (100 watts RMS).
Why pick the Turtlebox: Waterproof and crushproof, loud with punchy bass. Watch for: Sounds basically identical to the later Turtlebox Gen 2 and Turtlebox Gen 3: each generation mainly added features, not sound quality.
Buy the Monster Bambox. It is rated higher for sound quality and still sold new, while the Turtlebox is discontinued.
Worth knowing: the Monster Bambox has not been measured yet. Its rating is estimated from related models, with a likely range of 2.4 to 3.2, so treat this verdict as provisional.

Turtlebox: $329 Discontinued eBay
Newer model: the Turtlebox Gen 3, ranked higher, rated 2.1/5, released Feb 2025. See every Turtlebox generation.
Pros: Waterproof and crushproof, loud with punchy bass. 25 hour battery life (6 hours at full volume). Pairs with a second unit for stereo. Measured bass extension of ~65Hz (-10dB).
Cons: Sounds basically identical to the later Turtlebox Gen 2 and Turtlebox Gen 3: each generation mainly added features, not sound quality. The nearly identical Turtlebox Gen 3 measured a V shaped tuning, with boosted lows and highs and dipped mids, yet bass only down 10dB at about 65Hz, and only about 12W RMS from its amp; Turtlebox rated this one at just 50W. It rattles at high volume. Nowhere near its claimed 120dB at a standard one meter distance. It charges from an external AC power brick. Inside is essentially a car audio 6x9 two way speaker in a plastic box. Discontinued.
