Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It sinks. IP68 means submersible, not floating — drop the Charge 6 in a pool or lake and it goes straight to the bottom. If it might go in the water untethered, buy a floater instead.
Dealbreaker? Runner-up №1 is a floater — the Soundcore Boom 2 ↓

Submersible isn't floating
IP68 rates a speaker to survive going under — not to come back up. Only 2 of these 10 float (UE Wonderboom 4, Soundcore Boom 2). The IP68 JBL Charge 6, Flip 7, and Boombox 4 sink; drop one in a pool or lake and it's gone.
Battery marketing vs. measured
Ratings assume ~50% volume. SoundGuys measured the JBL Boombox 4 at ~22h against a 34h claim and the Flip 7 at ~6h at 80 dB. High volume, bass boost, and RGB lights cut real runtime by 30–60%.
Fresh water only — rinse after
IP68 and IPX7 submersion is rated for fresh water, 1–1.5m for 30 minutes — not saltwater. Chlorine and salt degrade the seals and grille, so rinse with fresh water after every pool or ocean session.
