We're talking about powerful sound, with deep and impactful bass. The redesigned JBL Boombox 4 comes equipped with two larger woofers, two tweeters, and three passive radiators, making every track sound more powerful and clearer. And with AI Sound Boost, we don't have to do anything — this intelligent technology analyzes our music in real time and adjusts the sound to deliver more power with less distortion, even at maximum volume.

Keep the party going from one party to the next... and on to the next, for up to 28 hours on a single charge. Forgot to charge for the next one? No problem. JBL Playtime Boost adds up to 6 extra hours for dancing, gliding, or whatever other moves you've got up your sleeve.
The JBL Boombox 4 is waterproof and dustproof with an IP68 protection rating, so it can withstand anything the weather, or our most clumsy friends, throw at it.

“Upgraded from the BOOMBOX 4 EXTREME to the BOOMBOX 4 EXTREME Wi-Fi and it was the best decision. The sound is more refined, clear, and powerful, with AAC codec support and a 7-band EQ on the JBL One app. Portable, impressive, and amazing for hours of listening — worth every penny. Can’t wait for the Boombox 4!”

Unbeatable sound all day long We crank up the volume our way, anywhere. The all-new JBL Boombox 4 is bigger, bolder, and better than ever, with powerful JBL Pro sound that stays loud and clear, with deep, booming bass. AI Sound Boost analyzes our music in real time and adjusts the sound to give us more power with less distortion, even when we crank up the volume. It comes with two larger woofers, two tweeters, and three passive radiators, so every track has more punch and sounds cleaner. When we want to adjust the vibe, simply switch between deep or vibrant bass boost settings to match our mood. We've given the classic Boombox design a new update; it's bigger but lighter, so we can take it wherever the party goes: to the beach, the block, or the backyard. It's IP68 waterproof and dustproof, so the weather is never an obstacle. And with up to 34 hours of playback (thanks to Playtime Boost), we're ready for long journeys. With the JBL Boombox 4, we bring vibe and energy wherever we go.
