JBL Charge 5 vs Flip 6: Charge 5 wins for beach days with better battery and bass

The Charge 5 is the Goldilocks of waterproof speakers—20-hour battery, IP67 waterproofing, and decent bass in a carry-friendly size. The Flip 6 is smaller but loses 8 hours of battery and some low-end punch. Both float and handle sand easily, but for a full day without charging, the Charge 5 is the clear pick.
