These are not really the same size class, and that is the honest framing here. The Turtlebox Gen 3 ranks #67 of 72 boombox speakers by sound quality at $430; the JBL Partybox 330 ranks #1 of 46 party speakers by sound quality at $629.95.
What the Turtlebox Gen 3 gets right: A much smaller, lighter package for anyone who doesn’t need party-size output. The catch: it ranks near the bottom of the boombox class here.
On the JBL Partybox 330 side: A full size class up in power and bass, with a removable battery, wheels and handle, a customizable lightshow, and inputs for karaoke and live sets. The tradeoff: it’s very large, and JBL’s daisychain party mode only works with other JBL speakers.
Buy the Turtlebox Gen 3 at $430 if you want a boombox speaker. Buy the JBL Partybox 330 at $629.95 if you want a party speaker instead.
If sound quality matters at all to you, skip the Turtlebox Gen 3. It ranks near the bottom of the 72 boombox speakers, so look higher up the list instead.
If water resistance matters to you, the Turtlebox Gen 3 at IP67 (brief submersion) holds up far better than the JBL Partybox 330 at IPX4 (splashing).

The Two Speakers In Full
Turtlebox Gen 3: $430 Amazon
Pros: 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.
Cons: 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.

JBL Partybox 330: $629.95 Amazon Bhphotovideo
Pros: Handle and wheels are convenient. Customizable lightshow. Removable battery. Slightly more power than the 310 and Stage 320 (280W vs 240W). Adds an optical TV input and USB-C lossless playback, plus dual mic and guitar inputs for karaoke and live sets.
Cons: Sound quality is nearly identical to the 310 and Stage 320 despite the power bump, so probably not worth an upgrade if you already own either of those. Removed the dedicated mic gain and microphone control knobs found on the 310/320. Some people don’t like the new lightshow design. Very large. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.
