Short answer: both are discontinued, so this only matters if you are buying used. Used, the Teufel Boomster 2021 is the better pick: it ranks #46 of 91 boombox speakers by sound quality (rated 3.4/5), against #87 (rated 2.1/5) for the Turtlebox. If you want one new, the Teufel Boomster 4 replaces the Teufel Boomster 2021 and is rated 3.4/5.
The Turtlebox is the longer-running option. Waterproof and crushproof, loud with punchy bass. It is rated for 25 hours of battery against 18 for the Teufel Boomster 2021. The tradeoff: Sounds basically identical to the later Turtlebox Gen 2 and Turtlebox Gen 3: each generation mainly added features, not sound quality.
The Teufel Boomster 2021 is the better-sounding option.
Buy the Teufel Boomster 2021 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Teufel Boomster 4, which replaces the Teufel Boomster 2021.

The Two Speakers In Full
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.
