Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sony ULT Tower 5 ranks #5 of 40 party speakers by sound quality at $448; the Turtlebox Gen 3 ranks #71 of 76 boombox speakers by sound quality at $430.
What the Sony ULT Tower 5 does well: At $448, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. Watch for: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance.
Why pick the Turtlebox Gen 3: Waterproof and crushproof, loud with punchy bass. The catch: Sounds basically identical to the original and the Gen 2: each generation mainly added features, not sound quality.
Buy the Sony ULT Tower 5 at $448 if you want a party speaker. Buy the Turtlebox Gen 3 at $430 if you want a boombox speaker instead.
Water resistance is not close: the Turtlebox Gen 3 is rated at IP67 (brief submersion), well ahead of the Sony ULT Tower 5 at IPX4 (splashing).

The Two Speakers In Full
Sony ULT Tower 5: $448.00 Amazon eBay
Pros: At $448, its 300W system with a 9-inch woofer delivers a notably capable party-speaker package: a removable 20-hour battery, IPX4 splash resistance, 10-band EQ and ULT1/ULT2 modes. AudioTribe’s first impressions praise its deeper bass and clearer sound than the JBL PartyBox Club 120; it also has USB-C and USB-A, RCA, balanced XLR and mic inputs for DJ and karaoke use.
Cons: It has a shorter 20-hour battery claim than the Tower 7’s 30 hours, no wheels, and only IPX4 splash resistance. Its single-woofer, two-tweeter layout lacks the Tower 7’s 360-degree rear-driver array, and the reviewer describes the sound assessment as first impressions rather than a controlled measurement comparison.

Turtlebox Gen 3: $430.00 Amazon eBay
Older models: the Turtlebox Gen 2 (rated 2.1/5) and the Turtlebox (rated 2.1/5).
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. Measured bass extension of ~65Hz (-10dB).
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.
