JBL Boombox 4 Waterproof Portable Bluetooth Speaker
The all-new JBL Boombox 4 is bigger, bolder, and better than ever, delivering powerful JBL Pro Sound that stays loud and clear with deep, thumping bass. AI Sound Boost analyzes your music in real time and adjusts the audio to provide more power with less distortion, even at maximum volume. It features two larger woofers, two tweeters, and three passive radiators, so every track hits harder and sounds cleaner.
When you want to fine-tune the vibe, simply switch between deep or vibrant punchy Bass Boost settings to match your mood. JBL has refreshed the classic Boombox design—making it larger yet lighter—so you can take it wherever the party goes: the beach, the block, or the backyard. With its IP68 waterproof and dustproof rating, weather is never an issue. And with up to 34 hours of playtime thanks to Playtime Boost, you're ready for the long haul. With the JBL Boombox 4, you bring the mood and energy everywhere you go.
