Short answer: these sit in different size classes, so this isn’t a straight ranking comparison. The Turtlebox Gen 3 ranks #105 of 113 boombox speakers by sound quality at $430; the JBL Partybox Stage 320 ranks #3 of 53 party speakers at $569.95. Pick based on what you’re actually carrying it for, not a head-to-head sound comparison.

Sound quality is not a reason to pick the Turtlebox. Its cons describe it as sounding basically identical to the original and the Gen 2, with each generation mainly adding features rather than sound quality, and note it sounds horrible in YouTube sound samples with barely any bass and rattling at high volume. The cons also flag that it will never hit its claimed 120dB output at the standard 1-meter measuring distance. The Partybox Stage 320’s cons are much narrower by comparison: slight sibilance in the treble at full blast, and its large size.
What the Turtlebox Gen 3 gets right is portability. It weighs 10 lbs (4.5 kg) against the Stage 320’s 36.4 lbs (16.5 kg), runs 25-plus hours on battery versus 18, and is IP67 rated for brief submersion versus the Stage 320’s splash-resistant IPX4. It’s built to survive being thrown around outdoors, which the much larger, wheeled Partybox is not designed for.
What the JBL Partybox Stage 320 adds: a full size class of output at 240W against the Turtlebox’s 50W, a removable battery, wheels and a telescoping handle for moving it, customizable color lighting, a 5-band app EQ, karaoke mic and guitar inputs, and Auracast party linking. The Turtlebox’s own party mode only links to other Turtlebox units.
Buy the Turtlebox Gen 3 if you need a small, rugged, waterproof speaker for outdoor or work-site use and sound quality isn’t the priority.
Buy the JBL Partybox Stage 320 if you want an actual party speaker with real output, an EQ, and karaoke features, and can handle the size and weight.
