Short answer: the Sony SRS-XG500. It ranks #45 of 73 boombox speakers by sound quality at $334.99; the Turtlebox Gen 3 ranks #68 and costs $430, so there is not much of a tradeoff to weigh.
What the Turtlebox Gen 3 offers: Waterproof and crushproof, loud with punchy bass. 25+ hour battery life. USB-C charging and USB-C output charges other devices. True multi-speaker Party Mode added on top of stereo pairing, plus Bluetooth 5.4. Watch for: Sounds basically identical to the original and the Gen 2: each generation mainly added features, not sound quality. They pretty much lie about all their specs and sound horrible in all youtube sound samples. Will never hit its claimed 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.
What the Sony SRS-XG500 offers: 30 hour battery life; 10-min quick-charge gives 3 hours. Battery care function stops charging at 90% to extend longevity. IP66 water/dust resistant. Two USB-A ports (one charges devices), mic/guitar inputs, AUX. Party mode links 100+ speakers. Watch for: Thuddy upper bass, not as deep bass as others. Speaker will not remain at max volume and will turn itself down automatically.
Buy the Sony SRS-XG500. It ranks higher for sound quality than the Turtlebox Gen 3 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Turtlebox Gen 3. It ranks near the bottom of the 73 boombox speakers, so look higher up the list instead.
