JBL Boombox 4 – Portable Bluetooth Speaker with Massive Sound

Key Features

Powerful JBL Pro Sound with two 5” woofers, two tweeters and three passive radiators for deep, punchy bass and clear highs.

Smart “AI Sound Boost” optimizes audio in real time for maximum power with minimal distortion, even at high volume.

Up to 28 hours battery life per charge; up to 34 hours with Playtime Boost — great for all-day events, outdoor use, or long trips.

IP68 waterproof and dustproof rating — safe for beach, poolside, backyard or outdoor adventures.

Wireless Bluetooth 5.4 with multi-speaker connectivity via Auracast™ — link with other compatible speakers for bigger sound.

USB-C port supports lossless audio playback when connected via cable — useful for high-quality wired listening.

Why It Stands Out

Boombox 4 combines powerful, room-filling sound, long battery life, and weather-ready durability — making it ideal for outdoor parties, beach or pool gatherings, travel, or big indoor events. Its Bass Boost options and smart audio processing ensure you get tailored sound, whether you want deep bass for Afrobeat or crisp, balanced output for genres with vocals. With wireless multi-speaker pairing and robust build, it’s a versatile speaker for both everyday use and big group settings.
