Product Details
- Unbeatable JBL Pro Sound with AI Sound Boost: We’re talking massive sound with deep and punchy bass. The redesigned JBL Boombox 4 packs in two bigger woofers, two tweeters and three passive radiators, so every track hits harder and sounds cleaner. And with AI Sound Boost, we don’t have to lift a finger—this smart technology analyzes our music in real time and adjusts the sound to give us more power with less distortion, even when we turn it all the way up.
- Up to 34 hours of playtime: Keep the vibe alive from party to party… to party, for up to 28 hours on a single charge. Forgot to charge up for the next one? It’s all good. JBL Playtime Boost adds up to 6 hours of extra popping, locking, sliding, or whatever moves you got left in that bag.
- Waterproof and dustproof: The JBL Boombox 4 is IP68 waterproof and dustproof, so it can handle whatever the weather—or our clumsiest friends—throw at it.
- Bigger and louder, but lighter: The JBL Boombox 4 sounds bigger and better than ever—but here’s the real win: we redesigned it to be lighter than before. So now it’s way easier to set the tone wherever we go. Lossless audio playback: Want to hear every detail? Plug into your laptop or other audio device using the Boombox 4’s USB-C port* to enjoy lossless audio playback. It's perfect for real audio fans who want more from their music. Just make sure your source offers lossless audio. *Requires compatible lossless audio content from supported apps or services.
- The included weather-resistant case features: Fully-zippered design, Textured padded interior, Light-weight material for portability
