Short answer: these solve different problems. The Partybox 330 ranks #15 of 53 party speakers, the Eon One Compact ranks #2, and the Eon One Compact costs $30.95 less. But the gap in rank reflects a gap in purpose, not just sound quality.
The Eon One Compact is built to be a small PA system, not a party speaker. Our notes highlight a professional 4-channel mixer with XLR/TRS preamps and phantom power for condenser microphones, high-efficiency drivers our notes say reach two to three times the volume of typical speakers at the same wattage, and a ducking feature that auto-lowers music when it detects speech. It is meant for DJ sets, live vocals, guitar, and corporate talks as much as Bluetooth streaming. The tradeoff is real: our notes describe it as quite distorted at full volume with rolled-off treble and no stereo imaging.
The Partybox 330 is the more polished party speaker. Our notes say its sound quality is nearly identical to the older Partybox 310 and Stage 320 despite its power bump to 280W, so the difference here isn’t really about wattage. What it adds is a wheeled, handled cabinet, a customizable lightshow, a removable battery, an optical TV input, USB-C lossless playback, and dual microphone and guitar inputs for karaoke. It also runs longer: 18 hours against the Eon One Compact’s 12, and it carries an IPX4 splash rating the Eon One Compact lacks entirely.
Buy the Eon One Compact if you need an actual mixer with real microphone preamps, for live performance, speeches, or busking, and can tolerate some distortion pushed to its limit.
Buy the Partybox 330 if you want a speaker built for parties: wheels, lights, karaoke inputs, splash resistance, and a longer battery, at $30.95 more than the Eon One Compact.
There is a real gap in water resistance: the JBL Partybox 330 at IPX4 (splashing) against the JBL Eon One Compact, which has no water resistance.
