Short answer: these solve different problems, and the Stage 320 is the better-reviewed of the two for its own job. The Stage 320 is a party and karaoke speaker built for lights, bass and crowd volume. The Eon One Compact is a portable PA: a 4-channel mixer with XLR/TRS preamps and phantom power, meant for a performer running vocals, an instrument and backing tracks through one box.
The Eon One Compact is built for people mixing live sound, not throwing a party. Its 8-inch woofer extends to a claimed 37.5Hz and it reaches 112dB SPL, with a swappable 12-hour battery and a proper mixer up front for XLR mics, guitars and a Bluetooth source at once. Reviewers note it’s quite distorted at full volume and the treble is rolled off, and it’s mono, not stereo. At $699 it also costs more than the Stage 320.
The Stage 320 is the pick for an actual party. It has the lights, karaoke echo mode, dual mic/guitar inputs, a removable battery and Auracast for linking speakers, all things the Eon One Compact doesn’t offer. Its own weak point is a slightly sibilant treble at full blast, and at $499.95 it’s the cheaper of the two.
Buy the Stage 320 for a party, karaoke night or anything where lights and crowd-pleasing bass matter more than a clean mixed signal.
Buy the Eon One Compact if you’re a performer who needs XLR inputs, phantom power and a real mixer in a portable, battery-powered box.
Battery life favors the JBL Partybox Stage 320: rated for 18 hours against 12 hours for the JBL Eon One Compact.
There is a real gap in water resistance: the JBL Partybox Stage 320 at IPX4 (splashing) against the JBL Eon One Compact, which has no water resistance.
