These are not really the same size class, and that is the honest framing here. The JBL Boombox 4 ranks #20 of 76 boombox speakers by sound quality at $429.95; the Soundcore Rave 3S ranks #17 of 40 party speakers by sound quality at $299.99.

Why pick the JBL Boombox 4: Pretty insane output capability for the size. The tradeoff: Pretty overpriced for the category.
What the Soundcore Rave 3S does well: 2 AA battery Wireless Microphones and remote control included. The catch: Some upper bass and upper mids boost.
Buy the JBL Boombox 4 at $429.95 if you want a boombox speaker. Buy the Soundcore Rave 3S at $299.99 if you want a party speaker instead.
There is a real battery-life gap here: the JBL Boombox 4 is rated for 28 hours, the Soundcore Rave 3S only 12 hours.
If water resistance matters to you, the JBL Boombox 4 at IP68 (extended submersion) holds up far better than the Soundcore Rave 3S at IPX4 (splashing).

JBL Boombox 4: $429.95 Amazon B&H Photo Video eBay
Older models: the JBL Boombox 3 (rated 3.8/5), the JBL Boombox 2 (rated 3.5/5) and the JBL Boombox (rated 2.9/5).
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
