Short answer: the Diamondboxx M3 for better sound quality, the ION Pathfinder 280 for the lower price. The Diamondboxx M3 ranks #53 of 75 boombox speakers at $700. The ION Pathfinder 280 ranks #68 at $169.99, $530.01 cheaper.
What the Diamondboxx M3 offers: An unusually compact 5kg high-output boombox, with a claimed 200W RMS Class A/B amplifier, 114dB maximum level, active crossovers and a choice of large battery packs. It has aux input, USB-C power and TWS pairing, while the aluminum heat sink is designed to sustain loud playback without thermal shutdown. Watch for: Despite its output, bass does not reach as deep as the best large portables and can distort when pushed hard. The treble-forward tuning can sound aggressive, there is no app or EQ to correct it, and the lack of a water rating makes it a poor match for poolside or rough-weather use.
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 Diamondboxx M3 if sound quality is the priority over the price, or the ION Pathfinder 280 if the price is the priority over sound quality.
If sound quality matters at all to you, skip the ION Pathfinder 280. It ranks near the bottom of the 75 boombox speakers, so look higher up the list instead.
There is a real battery-life gap here: the ION Pathfinder 280 is rated for 100 hours, the Diamondboxx M3 only 40 hours.
Water resistance is not close: the ION Pathfinder 280 is rated at IPX5 (water jets), well ahead of the Diamondboxx M3 at no water resistance.
