Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Soundcore Rave 3S ranks #20 of 53 party speakers by sound quality at $299.99; the JBL Partybox On the Go ranks #67 of 113 boombox speakers by sound quality at $329.95.
The Soundcore Rave 3S is the longer-running option. A big party speaker with two wireless microphones, a remote, and a vocal removal feature for karaoke nights. It is rated for 12 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: Some upper bass and upper mids boost.
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 noticeably less than the Soundcore Rave 3S at 21.6 lbs (9.8 kg). The tradeoff: Battery life is short, and its sound trails the rest of the Partybox line.
Buy the Soundcore Rave 3S ($299.99) for a party speaker; the JBL Partybox On the Go ($329.95) suits a boombox speaker instead.
