These are not really the same size class, and that is the honest framing here. The Onn Large Party gen 2 ranks #17 of 53 party speakers by sound quality at $129; the JBL Partybox On the Go ranks #67 of 113 boombox speakers by sound quality at $329.95.
The Onn Large Party gen 2 is the longer-running choice. A budget party speaker on wheels with real bass impact, karaoke inputs and an FM radio. It is rated for 12 hours of battery against 6 for the JBL Partybox On the Go. It links with other speakers (Party Sync Mode), which the JBL Partybox On the Go cannot. The tradeoff: The low price shows in the refinement.
The JBL Partybox On the Go is the lighter choice. A battery party speaker with an included wireless microphone and a detachable shoulder strap. At 16.5 lbs (7.5 kg) it weighs noticeably less than the Onn Large Party gen 2 at 20.9 lbs (9.5 kg). The tradeoff: Battery life is short, and its sound trails the rest of the Partybox line.
Buy the Onn Large Party gen 2 at $129 if you want a party speaker. Buy the JBL Partybox On the Go at $329.95 if you want a boombox speaker instead.
