Short answer: the Zealot ZE21 if sound quality matters most, the ION Pathfinder 280 if price matters most. The Zealot ZE21 ranks #17 of 75 boombox speakers at $247.41. The ION Pathfinder 280 ranks #68 at $169.99, $77.42 cheaper.
What the Zealot ZE21 offers: The ZE21’s main attraction is unusually deep bass for a battery boombox: owner testing finds real output in the 40-50Hz region and audibility down toward the low 30s. Its TWS button can form a stereo pair with another compatible Zealot, and its large, rugged chassis gives it credible party-speaker scale. Watch for: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy. The supplied sound modes do not fully correct the tuning; the most positive independent report required source-side parametric EQ. Treble is also soft and clarity trails better-tuned rivals.
What the ION Pathfinder 280 offers: A practical all-day event speaker with an exceptionally long claimed 68-hour battery, wheels, telescoping handle, FM radio, lighting and a full graphic EQ/presets. RTINGS finds it gets loud with relatively little compression, and its wide dispersion makes it a useful choice for outdoor background music or casual gatherings. Watch for: Out of the box, the midrange and treble are uneven enough to sound alternately honky and dull, and the bass does not extend as deeply as better party speakers. It is heavy, only IPX5 splash-resistant, and cannot produce a true stereo image from one cabinet. Use the EQ before judging its sound.
Buy the Zealot ZE21 if sound quality is the priority over the price, or the ION Pathfinder 280 if the price is the priority over sound quality.
Skip the ION Pathfinder 280 if sound quality matters to you. It ranks near the bottom of the 75 boombox speakers.
Battery life favors the ION Pathfinder 280: rated for 100 hours against 40 hours for the Zealot ZE21.

Cons: That deep-bass emphasis comes with a pronounced 60-110Hz kick-bass dip and over-loud 250-600Hz lower mids, which can make rock and pop sound hollow or boxy.
