JBL Go 4 Compact Bluetooth Speaker — Black, IP67 Waterproof, 7‑Hour Battery

Compact enough to carry every day, the JBL Go 4 combines loud, clear audio with a rugged, outdoor-ready design. A redesigned integrated loop lets you clip or hang the speaker for hands-free transport, while recycled materials in the grille and sustainable packaging reduce environmental impact. Advanced features like Auracast multi-speaker pairing expand the soundstage when you want bigger audio without sacrificing portability.

Will it survive outdoor use—pools, beaches, or dusty trails?

How long does the battery last, and can I extend playtime?

• Up to 7 hours standard playback
• Playtime Boost adds approximately 2 extra hours
• Rechargeable battery with straightforward charging cable

Can I connect several speakers together for bigger sound?

Yes. The Go 4 supports stereo pairing of two units and can join multiple Auracast-enabled JBL speakers to create a larger synchronized audio setup. This makes it easy to scale sound for parties or shared listening across rooms.
