Short answer: the Onn Medium Party Speaker Gen 2. It ranks #45 of 75 boombox speakers by sound quality at $90; the Turtlebox Gen 3 ranks #70 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 Onn Medium Party Speaker Gen 2 offers: Under $100 with LED lights synced to music. Simple controls, solid Bluetooth range. Mic input for karaoke/emcee. Built-in FM radio with 16 presets. Aux port. Watch for: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass. Only available in the United States and Canada.
Buy the Onn Medium Party Speaker Gen 2. It ranks higher for sound quality than the Turtlebox Gen 3 and costs less, so there is no real case for the other one.
The Turtlebox Gen 3 is not a sound-quality pick. It sits near the bottom of the 75 boombox speakers; there are better options higher up.
