Description

Unbeatable sound all day long. Turn up the volume wherever you are. The all-new JBL Boombox 4 is bigger, bolder, and more refined than ever, delivering powerful JBL Pro Sound that's always clear and punchy, with deep bass.

The AI Sound Boost feature analyzes your music in real time and adjusts the audio to give you more power with less distortion, even at full volume. The speaker comes with two large woofers, two tweeters, and three passive radiators, so every track sounds sharper and more precise.

To match the mood, simply switch between the intense Bass Boost and the dynamic setting, or vice versa. With a refreshed classic design, the Boombox is larger yet lighter, so you can take it anywhere the party goes: the beach, the block, or the backyard.

Certified IP68, it's waterproof and dustproof, so the weather is never a problem. And with up to 34 hours of playtime (thanks to Playtime Boost), you can keep the party going all night long.

With the JBL Boombox 4, bring the vibe and the energy wherever you go.
