JBL Boombox 4 vs Turtlebox Gen 2

Last updated: October 1, 2026

Short answer: if battery and toughness come first, the Turtlebox Gen 2; if tuning does, the JBL Boombox 4. The Turtlebox is waterproof and crushproof, loud with punchy bass, and its 25 hour battery lasts 6 hours at full volume on a 3 hour charge. The Boombox 4 has pretty insane output for its size and a 7-band EQ, but it is overpriced and drops Aux, and the Turtlebox sounds basically identical to the original and the Gen 3 anyway.

JBL Boombox 4 ranking card

Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5).

Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).

Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.

Turtlebox Gen 2: $400 Discontinued eBay

Turtlebox Gen 2 ranking card

Newer model: the Turtlebox Gen 3, ranked higher, rated 2.1/5.

Pros: Waterproof (IP67) and crushproof, and loud: Outeraudio measured about 104 dB at one meter. An 85Wh battery rated for 25 hours at low volume and about 6 at full volume, a USB-C output that charges other devices, aux and 3.5mm microphone inputs, and stereo pairing with a second Gen 2. Measured bass extension of ~65Hz (-10dB).

Cons: Sounds basically identical to the original and the Gen 3: each generation mainly added features, not sound quality. The nearly identical Gen 3 measured a V shaped tuning, with boosted lows and highs and dipped mids, yet bass only down 10dB at about 65Hz, and only about 12W RMS from its amp; Turtlebox rated this one at just 50W. Outeraudio found its balance and treble middling, with slight harshness at higher volumes, and it rattles at high volume. Nowhere near its claimed 120dB at a standard one meter distance. It charges only from its own barrel plug adapter, not USB-C, and has no app, EQ or party mode. Inside is essentially a car audio 6x9 two way speaker in a plastic box. Discontinued.
