Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox Stage 320 ranks #3 of 51 party speakers by sound quality at $499.95; the Audiocase S10 ranks #14 of 17 battery-powered PA speakers by sound quality at $892.

The JBL Partybox Stage 320 is the tougher pick. An excellent sounding party speaker, with deep bass that holds up at high volume, wheels, a removable battery and mic inputs. It is rated IPX4, while the Audiocase S10 has no water resistance. It links with other speakers (Auracast), which the Audiocase S10 cannot. It has an adjustable EQ, which the Audiocase S10 lacks. The tradeoff: Slightly sibilant in the treble at full blast.
The Audiocase S10 is the longer-running choice. A very loud battery PA speaker, with two 10 inch woofers, a removable 30 hour battery, and mic or instrument inputs. It is rated for 30 hours of battery against 18 for the JBL Partybox Stage 320. It supports aptX Bluetooth, which the JBL Partybox Stage 320 lacks. The tradeoff: Not great sounding at low volumes.
One note: the Audiocase S10 is discontinued and no longer widely available new.
Buy the JBL Partybox Stage 320 at $499.95 if you want a party speaker. Buy the Audiocase S10 at $892 if you want a battery-powered PA speaker instead.
