These are not really the same size class, and that is the honest framing here. The JBL Partybox Stage 320 ranks #3 of 53 party speakers by sound quality at $569.95; the JBL Partybox On the Go ranks #67 of 113 boombox speakers by sound quality at $329.95.
The JBL Partybox Stage 320 is the longer-running choice. An excellent sounding party speaker, with deep bass that holds up at high volume, wheels, a removable battery and mic inputs. It is rated for 18 hours of battery against 6 for the JBL Partybox On the Go. It links with other speakers (Auracast), which the JBL Partybox On the Go cannot. It has an adjustable EQ, which the JBL Partybox On the Go lacks. The catch: Slightly sibilant in the treble at full blast.
The JBL Partybox On the Go is the lighter pick. A battery party speaker with an included wireless microphone and a detachable shoulder strap. At 16.5 lbs (7.5 kg) it weighs much less than the JBL Partybox Stage 320 at 36.4 lbs (16.5 kg). The tradeoff: Battery life is short, and its sound trails the rest of the Partybox line.
Buy the JBL Partybox Stage 320 at $569.95 if you want a party speaker. Buy the JBL Partybox On the Go at $329.95 if you want a boombox speaker instead.
