Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Wet Sounds WS-L ranks #33 of 54 party speakers by sound quality at $524.99; the JBL Boombox 4 ranks #20 of 113 boombox speakers by sound quality at $549.95.
The Wet Sounds WS-L is the longer-running option. A rugged marine party speaker built for boats and beaches, fully waterproof with a removable long life battery and app controlled lights. It is rated for 40 hours of battery against 28 for the JBL Boombox 4. The tradeoff: No independent measurements or side by side tests against other party speakers have been published, so its 126dB rating, bass extension and tonal balance are unverified.
The JBL Boombox 4 is the lighter pick. An extremely loud boombox for its size with fully waterproof, dustproof build, a long battery and a flexible app EQ. At 13.2 lbs (5.98 kg) it weighs much less than the Wet Sounds WS-L at 24.9 lbs (11.3 kg). It plays in stereo from a single unit, unlike the Wet Sounds WS-L. Watch for: Pretty overpriced for the category.
Buy the Wet Sounds WS-L at $524.99 for a party speaker, or the JBL Boombox 4 at $549.95 for a boombox speaker instead.
