Customers have good things to say about this speaker, particularly highlighting its impressive sound quality and reliable battery life. Users also frequently appreciate its portability, noting that the handle makes it easy to carry, while also praising its ability to reach high volumes without distortion. Additionally, the device is well-regarded for its convenient connectivity and water-resistant design, making it a versatile choice for various environments.
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 tech 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.
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.
The JBL Boombox 4 is IP68 waterproof and dustproof, so it can handle whatever the weather—or our clumsiest friends—throw at it.
Wouldn't it be great to share the whole mood with the whole crew? With Auracast™, effortlessly stereo pair two Boombox 4 speakers for a wider sound stage or connect multiple Auracast™-enabled JBL speakers to cover more ground with the same playlist.
Two Bass Boost settings to match our vibe
