These are not really the same size class, and that is the honest framing here. The JBL Partybox 300 ranks #10 of 46 party speakers by sound quality at $300; the JBL Eon One Compact ranks #15 of 16 battery-powered PA speakers by sound quality at $699.
The JBL Partybox 300 is the longer-running pick. Exceptional sound quality with crisp, crystal clear highs and midranges, hard punchy bass without muddiness. It is rated for 18 hours of battery against 12 for the JBL Eon One Compact. The tradeoff: Hard to carry, too tall, drags on the ground.
The case for the JBL Eon One Compact: Professional 4-channel mixer with XLR/TRS preamps, phantom power for condenser mics. Watch for: Quite distorted at full volume.
Worth knowing: the JBL Partybox 300 is discontinued, though it still ranks #10 of 46 party speakers by sound quality, so a used unit beats most of what is still sold new. The JBL Partybox 300’s replacement, the JBL Partybox 330, is rated 4.6/5 at $629.95.
Buy the JBL Partybox 300 at $300 for a party speaker, or the JBL Eon One Compact at $699 for a battery-powered PA speaker instead.
