Description
The all-new JBL Boombox 4 is bigger, bolder and better than ever. Dual 5-inch woofers, dual 0.75-inch tweeters and three passive radiators deliver a massive 210W RMS on AC power (200W RMS on battery), with AI Sound Boost analyzing your music in real time for more power with less distortion—even at full volume. Two Bass Boost modes, Deep and Punchy, let you tune the low end to your mood.
Up to 28 hours of playtime keeps the party going all day and night, extendable to 34 hours with Playtime Boost. The IP68 waterproof and dustproof build shrugs off the beach, the pool and the rain, and the replaceable battery design keeps the Boombox 4 playing for years. Bluetooth 5.4 with Auracast pairs multiple speakers or creates a stereo pair, and USB-C delivers lossless digital audio.
Freshly redesigned and 12% lighter at 5.89kg with an integrated carry handle, the Boombox 4 is ready for the backyard, the block or the beach. The USB-C port doubles as a power bank for your devices, and the JBL Portable app unlocks EQ, updates and multi-speaker control.
