Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the ZZA K8 is the better pick: it ranks #64 of 91 boombox speakers by sound quality (rated 2.9/5), against #87 (rated 2.1/5) for the Turtlebox. If you want one new, the Turtlebox Gen 3 replaces the Turtlebox and is rated 2.1/5 at $430. Both are rated below 3.0/5 among the 91 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $199.99.
Why pick the Turtlebox: Waterproof and crushproof, loud with punchy bass. Watch for: Sounds basically identical to the later Turtlebox Gen 2 and Turtlebox Gen 3: each generation mainly added features, not sound quality.
The ZZA K8 is the better-sounding, lighter choice. Completely insane value for the money. At 6.8 lbs (3.1 kg) it weighs noticeably less than the Turtlebox at 10 lbs (4.54 kg). The tradeoff: Very V curve frequency response, can be harsh in the treble range.
Buy the ZZA K8 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 Turtlebox Gen 3, which replaces the Turtlebox.

The Two Speakers In Full
Turtlebox: $329 Discontinued eBay
Newer model: the Turtlebox Gen 3, ranked higher, rated 2.1/5, released Feb 2025. See every Turtlebox generation.
Pros: Waterproof and crushproof, loud with punchy bass. 25 hour battery life (6 hours at full volume). Pairs with a second unit for stereo. Measured bass extension of ~65Hz (-10dB).
Cons: Sounds basically identical to the later Turtlebox Gen 2 and 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. It rattles at high volume. Nowhere near its claimed 120dB at a standard one meter distance. It charges from an external AC power brick. Inside is essentially a car audio 6x9 two way speaker in a plastic box. Discontinued.

ZZA K8: $40 after clipped coupon Discontinued eBay
Pros: Completely insane value for the money. Comes with 2 metal body wireless microphones that are USB-C chargeable. Comes with Chinese labeled infrared remote control. Has voice delete function that works quite well. Adjustable microphone reverb. Pretty good build quality. The default EQ is the most balanced, the other two sound muffled.
Cons: Very V curve frequency response, can be harsh in the treble range. Treble is boosted a good +10dB. Midbass is recessed. Slight distortion issue at all volume levels due to the bass high pass filter being set too low. Discontinued and no longer sold new.
