Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Zealot S89 ranks #19 of 113 boombox speakers by sound quality at $193.58; the Soundcore Rave 3S ranks #20 of 53 party speakers by sound quality at $299.99.
The Zealot S89 is the longer-running, lighter option. A great value boombox with deep bass, very high volume, a 40 hour battery and water resistance for outdoor parties. It is rated for 40 hours of battery against 12 for the Soundcore Rave 3S. At 16.1 lbs (7.3 kg) it weighs noticeably less than the Soundcore Rave 3S at 21.6 lbs (9.8 kg). It is rated IPX6 against IPX4 for the Soundcore Rave 3S. The catch: At high volume, listener reports describe the bass as loose or muddy and the overall balance as less clear than better boombox speakers.
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 tradeoff: Some upper bass and upper mids boost.
Buy the Zealot S89 at $193.58 for a boombox speaker, or the Soundcore Rave 3S at $299.99 for a party speaker instead.
