■  The catch — co-equal billing, always

It's heavy and pricey. At 14.4 lb it's a two-handed carry, and at $550 it's the most expensive speaker here by far — flagship money for headroom most buyers never use. The Charge 6 covers 90% of outdoor needs for a third of the price.

Dealbreaker? Runner-up №1 (Charge 6) covers most needs for 1/3 the price ↓

Traps — this verdict avoids

Why the JBL Boombox 4 is right for you

It avoids every trap below — and for anyone, no budget cap, it is the pick because it delivers:

Best-tested overall Truly submersible Longest battery Concert volume Runs forever on AC
Trap 01

The X is a hole

Only IP67 or IP68 certifies dust and water. The 'X' in IPX7 means dust was never tested — fine for rain and pool splashes, but blown beach sand abrades the drivers on a real beach. Soundcore's Boom 2 line is IPX7.

Trap 02

Phantom battery hours

Advertised playtime assumes ~50–65% volume with RGB and BassUp off. Turn on the lights, the bass boost, or real party volume and runtime drops 30–60%.

Trap 03

'Outdoor speakers' with no amp

The installed pairs here — Polk Atrium, Bose 251, Klipsch AW-650, Definitive AW6500 — are passive: no amplifier inside. Budget another $200–500 for a weatherproof amp and direct-burial wire before they make a sound.
