Short answer: the Partybox 720 for most backyard and event use. It ranks #6 out of 17, ahead of the Soundboks 4 at #10, and costs $99.05 less.
The 720 packs in more for the money. Its pros describe it as JBL’s most powerful battery-equipped Partybox, combining 800W of output, two removable batteries, wheels, a light show, Auracast, USB-C playback, app EQ, and karaoke and guitar inputs. Independent testing cited in its notes confirms very high output, strong bass, and a flexible 5 or 7 band EQ, enough to easily cover a backyard or large event. Its cons are mostly about handling: at 68.3 lbs (31 kg) and 94cm tall it’s still cumbersome despite the wheels, its front-facing vertical driver layout gives uneven sound to listeners at the sides or behind it, bass compresses at very high volume, and reviewers note a faint hiss. The default tuning is dark and bass-heavy, so it needs the app EQ to sound its best.
The Soundboks 4 is built for a different priority: efficiency and runtime. Its pros call it tied for the loudest battery-powered speaker, with a removable 40 hour battery and high efficiency drivers that reach 2 to 3 times the volume of typical speakers for the same wattage output. Its cons are direct: it’s very large, not as neutral or as deep in the bass as the Partyboxes, not stereo, and it relies on an external power brick for charging.
Buy the Partybox 720 if you want more built-in features (karaoke, guitar input, Auracast, app EQ) and stronger bass for less money.
Buy the Soundboks 4 if all-day battery life and maximum output-per-watt for large outdoor spaces matter more to you than app features or bass depth.
