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 #86 (rated 2.1/5) for the Turtlebox Gen 2. If you want one new, the Teufel Boomster 4 replaces the Teufel Boomster 2021 and is rated 3.4/5.
The Turtlebox Gen 2 is the longer-running pick. Waterproof (IP67) and crushproof, and loud: Outeraudio measured about 104 dB at one meter. It is rated for 25 hours of battery against 18 for the Teufel Boomster 2021. The tradeoff: Sounds basically identical to the original and the Turtlebox Gen 3: each generation mainly added features, not sound quality.
The Teufel Boomster 2021 is the better-sounding choice.
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 Gen 2: $400 Discontinued eBay
Newer model: the Turtlebox Gen 3, ranked higher, rated 2.1/5, released Feb 2025. It adds party mode.
Older model: the Turtlebox (ranked lower, rated 2.1/5). See every Turtlebox generation.
Pros: Waterproof (IP67) and crushproof, and loud: Outeraudio measured about 104 dB at one meter. An 85Wh battery rated for 25 hours at low volume and about 6 at full volume, a USB-C output that charges other devices, aux and 3.5mm microphone inputs, and stereo pairing with a second Gen 2. Measured bass extension of ~65Hz (-10dB).
Cons: Sounds basically identical to the original and the 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. Outeraudio found its balance and treble middling, with slight harshness at higher volumes, and it rattles at high volume. Nowhere near its claimed 120dB at a standard one meter distance. It charges only from its own barrel plug adapter, not USB-C, and has no app, EQ or party mode. Inside is essentially a car audio 6x9 two way speaker in a plastic box. Discontinued.
