The JBL Boombox 4 Portable Bluetooth Speaker in black is designed for those who want powerful, room-filling sound without compromising on portability. Delivering unbeatable JBL Pro Sound, it’s enhanced by AI Sound Boost, which intelligently adapts audio performance for richer clarity and deeper bass across any setting. With up to 34 hours of playtime, it keeps the music going all day and well into the night, making it ideal for outdoor gatherings, trips, or long weekends away. Built to handle the elements, its waterproof and dustproof design offers peace of mind wherever it’s used. Two selectable bass boost settings let listeners tailor the low-end punch to suit the mood, while lossless audio playback ensures a more detailed and immersive listening experience. Despite being bigger and louder, it’s been engineered to remain lighter and easier to carry. With Auracast multi-speaker connection, it can link with other compatible speakers to create an even more expansive and dynamic sound setup.
