Short answer: the ION Pathfinder 280 on measured sound quality, the Zealot S78 on price. The ION Pathfinder 280 ranks #68 of 75 boombox speakers at $169.99. The Zealot S78 ranks #75 at $159.68, $10.31 cheaper.
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.
What the Zealot S78 offers: A robust 4.4kg party speaker with claimed 120W RMS output, IP67 protection, USB-C charging, a power-bank function, aux, USB and microSD playback, TWS pairing and multiple EQ modes. Reviews find it very loud with useful bass and long claimed battery life, making it a credible choice for outdoor gatherings. Watch for: At high volume, reviews report distortion and fluctuating level, so its headline power is more useful below its maximum setting. It has no app-based EQ, and the bass and midrange refinement do not match better-established boombox speakers; assess its sound in person if tonal accuracy matters.
Buy the ION Pathfinder 280 if sound quality is the priority over the price, or the Zealot S78 if the price is the priority over sound quality.
Skip both if sound quality is the priority. There are better options higher up the 75 boombox speakers.
There is a real battery-life gap here: the ION Pathfinder 280 is rated for 100 hours, the Zealot S78 only 40 hours.
