Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Boombox 2 is the better pick: it ranks #40 of 91 boombox speakers by sound quality (rated 3.5/5), against #86 (rated 2.1/5) for the Turtlebox Gen 2. If you want one new, the JBL Boombox 4 replaces the JBL Boombox 2 and is rated 4.0/5 at $549.95.
The Turtlebox Gen 2 is the lighter option. Waterproof (IP67) and crushproof, and loud: Outeraudio measured about 104 dB at one meter. At 10 lbs (4.54 kg) it weighs noticeably less than the JBL Boombox 2 at 13 lbs (5.9 kg). It has a microphone input for karaoke or announcements, which the JBL Boombox 2 lacks. The tradeoff: Sounds basically identical to the original and the Turtlebox Gen 3: each generation mainly added features, not sound quality.
The JBL Boombox 2 is the better-sounding, deeper-bass option. 24 hour battery life (default volume); 20+ hours even at 60% volume. Its bass reaches about 46Hz before falling 10dB, against 65Hz for the Turtlebox Gen 2. It links with other speakers (PartyBoost up to 100 speakers), which the Turtlebox Gen 2 cannot. Watch for: Somewhat bass heavy and boomy.
Buy the JBL Boombox 2 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Boombox 4, which replaces the JBL Boombox 2.

The Two Speakers In Full
Turtlebox Gen 2: $400 Discontinued eBay
Newer model: the Turtlebox Gen 3, ranked higher, rated 2.1/5, released Feb 2025. It adds party mode.
Older model: the Turtlebox (ranked lower, rated 2.1/5). See every Turtlebox generation.
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 Turtlebox Gen 3: each generation mainly added features, not sound quality. The nearly identical Turtlebox 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.
