Product Information
More powerful yet tougher and longer-lasting than ever, the JBL Boombox 4 is an XL Bluetooth speaker that delivers above and beyond.
Big sound, wherever you go
Designed to go louder, for longer, the JBL Boombox 4 delivers deep, powerful sound in the toughest environments. Ideal for a pool party, the beach or simply for a BBQ at home, the versatile Boombox 4 has a long-lasting battery, with the option of a spare. When you want to calm it down and relish the detail, a USB-C connection provides the perfect link to lossless sound from your laptop.
Signature JBL sound, now with AI
A revised speaker system helps improve on the Boombox’s already impressive sound. Crisp at the top end and with JBL’s strong signature bass depth, this mighty speaker punches hard. JBL has also added its new proprietary tech, AI Sound Boost. This analyses the music in real time, delivering the most lifelike sound while reducing distortion to a minimum.
Choose your bass
For the bass that best suits your vibe, the JBL Boombox 4 has two settings. One touch of the Bass Boost button and, with the JBL Horn mark glowing orange, you get the maximum bass depth and power from the two woofers and three passive radiators. Press it again, the Horn mark turns white, and the bass is punchier and more agile.
Lossless audio
For the best in music detail and lifelike realism, connect via the USB-C port and enjoy lossless audio. Ideal for streaming lossless music files from your laptop or other device, the USB-C port takes playback quality up a level.
Auracast means that the Boombox 4 is just the beginning
Fitted with Auracast, it’s easy to wirelessly link two Boombox 4 speakers together and enjoy even more immersive sound. Ideal for larger spaces, paring two speakers significantly boosts the sound quality. If you want to cover even more space, you can wirelessly connect multiple Auracast-enabled JBL speakers for seamless multiroom sound.
The (battery) power to listen for longer
With up to 28 hours battery life, the Boombox 4 keeps going for longer. With the JBL Playtime Boost, you get up to an extra six hours, giving a total of 34 hours playback. If that’s still not enough, you can buy a second battery to slide in when you need.*
*JBL Battery 600 available at additional cost.
Built stronger than ever
Improved construction makes the Boombox 4 tougher than ever. Now rated at IP68, the speaker is tough enough to handle being dropped in water or having sand kicked in its face on the beach! This durability makes it the perfect speaker for everything from an outdoor adventure to a hard-working workshop space.
Pump up the volume, wherever your journey takes you, with the JBL Boombox 4.
