Turtlebox Gen 2 vs JBL Boombox 3

Last updated: August 25, 2026

Short answer: the JBL Boombox 3. It ranks #21 of 73 boombox speakers by sound quality at $349.95; the Turtlebox Gen 2 ranks #69 and costs $400, so there is not much of a tradeoff to weigh.

What the Turtlebox Gen 2 offers: Waterproof and crushproof, loud with punchy bass. 25 hour battery life (6 hours at full volume; 3 hour charge time). USB-C charging and USB-C output charges other devices, an upgrade over the original’s AC power brick. Pairs with a second unit for stereo. Watch for: Sounds basically identical to the original and the Gen 3: each generation mainly added features, not sound quality. They pretty much lie about all their specs and sound horrible in all youtube sound samples. Only 50w (from their indigogo page), will never hit 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 JBL Boombox 3 offers: IP67 rated. 24 hour battery life (6.5 hour charge time). Doubles as a power bank. PartyBoost links up to 100 compatible JBL speakers. Three-way speaker system with subwoofer. Watch for: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700hz, not quite as good mids and treble as the Blast.

Buy the JBL Boombox 3. It ranks higher for sound quality than the Turtlebox Gen 2 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 2. It ranks near the bottom of the 73 boombox speakers, so look higher up the list instead.
