Short answer: the Onn Medium Party Speaker Gen 2. It ranks #65 of 112 boombox speakers by sound quality, rated 3.1/5, at $90; the Turtlebox Gen 3 ranks #104, rated 2.1/5, and costs $430, so there is not much of a tradeoff to weigh.
The case for the Turtlebox Gen 3: A loud, waterproof and crushproof outdoor speaker with a big battery, device charging and party mode linking. It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2. Watch for: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality.
The Onn Medium Party Speaker Gen 2 is the better-sounding pick. An affordable waterproof party speaker with a big woofer, lights, a karaoke mic input and FM radio. The catch: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
Buy the Onn Medium Party Speaker Gen 2. It is rated higher for sound quality than the Turtlebox Gen 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
