These are not really the same size class, and that is the honest framing here. The Soundcore Rave 3S ranks #19 of 51 party speakers by sound quality at $299.99; the JBL Partybox Encore 2 ranks #4 of 112 boombox speakers by sound quality at $330.
The case for the Soundcore Rave 3S: A big party speaker with two wireless microphones, a remote, and a vocal removal feature for karaoke nights. The catch: Some upper bass and upper mids boost.
The JBL Partybox Encore 2 is the lighter pick. A compact karaoke party speaker with two wireless mics, better balanced sound than the original and a long battery. At 14.1 lbs (6.4 kg) it weighs noticeably less than the Soundcore Rave 3S at 21.6 lbs (9.8 kg). It plays in stereo from a single unit, unlike the Soundcore Rave 3S. The tradeoff: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
Buy the Soundcore Rave 3S at $299.99 if you want a party speaker. Buy the JBL Partybox Encore 2 at $330 if you want a boombox speaker instead.
