How long does the battery last on the JBL Pulse 4?

Up to 12 hours on a full charge — actual runtime depends strongly on light brightness and volume level. Using bright, sound-reactive light patterns will reduce playback time.

Is the Pulse 4 waterproof? Can I use it at the pool?

Yes — the Pulse 4 is IPX7 rated (submersible up to ~1 meter for up to 30 minutes). It’s pool-party safe, but rinse with fresh water and dry the charging port before plugging in. Don’t open ports while wet.

Can I link Pulse 4 with other JBL speakers?

Yes — use PartyBoost in the JBL Connect / JBL Portable app to pair multiple PartyBoost-compatible JBL speakers and sync audio; lightshow sync may depend on firmware versions. Update the speaker via the app for best compatibility.
