These sit in different size classes, so this is not a straight ranking comparison. The JBL PartyBox On-The-Go 2 Plus ranks #5 of 76 boombox speakers by sound quality at $419.95; the Soundcore Rave 3S ranks #17 of 40 party speakers by sound quality at $299.99.
Different sizes. The On-The-Go 2 Plus is a 6.45 kg boombox. The Rave 3S is a 9.8 kg party speaker. Each is rated within its own class.
Sound: in a side by side test the Rave 3S leaned brighter with more kick in its bass, while the On-The-Go 2 Plus had smoother, cleaner bass. The Rave 3S has some upper bass and upper mid boost.
Both remove vocals with AI. The Rave 3S includes two AA-powered wireless mics and a remote. The On-The-Go 2 Plus includes one rechargeable mic, which picked up less handling noise in testing.
Batteries: the On-The-Go 2 Plus uses a removable battery with a claimed 15 hours. The Rave 3S claims 12 hours and charges over USB-C, but its battery is not easy to swap. Both are IPX4.
Buy the JBL PartyBox On-The-Go 2 Plus ($419.95) for a boombox speaker; the Soundcore Rave 3S ($299.99) suits a party speaker instead.

The Two Speakers In Full
JBL PartyBox On-The-Go 2 Plus: $419.95 Amazon eBay
Older model: the JBL Partybox On the Go (rated 3/5).
Pros: Well balanced with strong vocals, and its front-firing bass ports give it cleaner, smoother bass than other PartyBoxes, so even the Punchy bass boost setting never overpowers the vocals. It gets a touch louder than the PartyBox Encore 2. EasySing AI vocal removal strips vocals from any song on the speaker itself, with 25%, 50% or 100% removal, and the included rechargeable wireless mic has a tight pickup pattern that rejects handling noise. A removable 34Wh battery shared with the Encore 2 and PartyBox 120, a claimed 15 hours, a padded shoulder strap, USB-C playback and charging, a 3.5mm aux input, Auracast and a light show.
Cons: The bass has less kick and physical impact than the Encore 2 or PartyBox Club 120, and the Club 120 gets noticeably louder. There is no wired microphone or guitar input, so more mics means buying JBL’s EasySing mics separately, and AI vocal removal is disabled while the speaker is linked to other speakers over Auracast. Real world battery life is closer to 7 hours at 80% volume with lights and bass boost on. IPX4 only covers splashes, the grille dents easily, and the battery must be installed for it to run even when plugged in.
