Short answer: the JBL Partybox 300. It ranks #8 of 50 party speakers by sound quality at $300; the JBL Eon One Compact ranks #36 and costs $549, which makes this an easy call rather than a real tradeoff.
What the JBL Partybox 300 offers: Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. 2x 6.5” woofers + 3x 2.25” tweeters, bass boost function, 45Hz-20kHz frequency range. 18-hour battery with 10400mAh capacity. Multiple inputs (RCA, USB, 3.5mm aux, mic, guitar). LED light modes (meter/pulse/party). True Wireless Stereo pairing up to 2 units. Watch for: Hard to carry, too tall, drags on the ground. Max spl and bass extension are only as good as the Partybox 100. No real reason to ever get one, get a Partybox 100 instead.
What the JBL Eon One Compact offers: Professional 4-channel mixer with XLR/TRS preamps, phantom power for condenser mics. 112dB SPL, lightweight 17.6 lbs with swappable 12-hour battery. 8-inch woofer extends to 37.5Hz. Versatile positioning (upright PA or floor monitor). Large clear controls. Ducking feature auto-lowers music when speech detected. Handles DJ sets, vocals, guitar, corporate talks, and Bluetooth streaming. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage. Watch for: Quite distorted at full volume. Treble is quite rolled off, not much clarity. Not stereo.
Buy the JBL Partybox 300. It ranks higher for sound quality than the JBL Eon One Compact and costs less, so the other one has nothing left to offer.
Battery life favors the JBL Partybox 300: rated for 18 hours against 12 hours for the JBL Eon One Compact.
