JBL Partybox 310 vs Bose S1 Pro

Last updated: September 2, 2026

Short answer: the JBL Partybox 310. It ranks #3 of 51 party speakers by sound quality at $499.95; the Bose S1 Pro+ ranks #16 and costs $699, which makes this an easy call rather than a real tradeoff.

On the JBL Partybox 310 side: Absolute deepest bass of any battery powered speaker, most balanced sound in the class, handle and wheels are convenient. Set against that: Very large.

What the Bose S1 Pro gets right: Extremely compact and light with flexible placement options. The catch: With full range music, it becomes distorted above ⅔ volume.

Buy the JBL Partybox 310. It ranks higher for sound quality than the Bose S1 Pro+ and costs less, so the other one has nothing left to offer.

There is a real battery-life gap here: the JBL Partybox 310 is rated for 18 hours, the Bose S1 Pro+ only 11 hours.

Water resistance is not close: the JBL Partybox 310 is rated at IPX4 (splashing), well ahead of the Bose S1 Pro+ at no water resistance.

Bose S1 Pro+: $699.00 Amazon eBay

Bose S1 Pro+ ranking card

Pros: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 XLR/quarter-inch combo mic-instrument + 1 line/Bluetooth), each with its own OLED display for quick treble/bass/reverb adjustment. Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode, plus a line out to daisy-chain a second unit. Optional WT-XLR/WT-INST wireless transmitters dock, pair, and charge right in the speaker for a cable-free mic or instrument. Up to 11 hours battery life. Professional build quality. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage.

Cons: With full range music, it becomes distorted above ⅔ volume, and reviewers describe it as screeching at max volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass. Ports are fully exposed with no water resistance. Charges via a less common three-prong AC cable instead of the two-prong barrel cable most rivals use.
