Short answer: the Yeahbox Sonic Boom Max 3. It ranks #54 of 91 boombox speakers by sound quality (rated 3.2/5) at $228.99 and is still sold new; the Turtlebox ranks #87 (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.
The Turtlebox is the lighter pick. Waterproof and crushproof, loud with punchy bass. At 10 lbs (4.54 kg) it weighs much less than the Yeahbox Sonic Boom Max 3 at 16.8 lbs (7.64 kg). Watch for: Sounds basically identical to the later Turtlebox Gen 2 and Turtlebox Gen 3: each generation mainly added features, not sound quality.
The Yeahbox Sonic Boom Max 3 is the better-sounding choice. A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. It has an adjustable EQ, which the Turtlebox lacks. Watch for: There is limited independent testing and the water/dust rating is reported inconsistently across listings.
Buy the Yeahbox Sonic Boom Max 3. It is rated higher for sound quality, and the Turtlebox is discontinued, so it is only available used.

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.

Yeahbox Sonic Boom Max 3: $228.99 Amazon eBay
Pros: A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. Listener comparisons describe powerful bass, strong output and decent mids and highs for outdoor party use.
Cons: There is limited independent testing and the water/dust rating is reported inconsistently across listings. Listener comparisons find it less clear and refined than stronger boombox rivals, so its big bass and output are a better fit for parties than critical listening.
