These sit in different size classes, so this is not a straight ranking comparison. The JBL Partybox 330 ranks #2 of 53 party speakers by sound quality at $629.95; the JBL Partybox On the Go ranks #67 of 113 boombox speakers by sound quality at $329.95.
The JBL Partybox 330 is the longer-running option. A rolling party speaker with deep bass, a removable battery, a light show and inputs for mics and a guitar. 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. Watch for: It remains very large and heavy, and the sound improvement over the JBL Partybox Stage 320 is modest rather than transformational.
The JBL Partybox On the Go is the lighter option. 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 330 at 37.7 lbs (17.1 kg). The catch: Battery life is short, and its sound trails the rest of the Partybox line.
Buy the JBL Partybox 330 ($629.95) for a party speaker; the JBL Partybox On the Go ($329.95) suits a boombox speaker instead.
