JBL Boombox 4 Portable Waterproof Bluetooth Speaker

JBL Pro Sound with AI Sound Boost

The JBL Boombox 4 combines JBL Pro Sound with AI Sound Boost, which analyzes music in real time and adjusts the audio signal to deliver greater power with less distortion, even at high volume. The system produces up to 200W of audio power, or 210W when connected to AC power, through two 5″ woofers, two 0.75″ tweeters, and three passive radiators.

Dual Bass Boost Modes

Two 5″ woofers and three passive radiators deliver deep, powerful bass with a wide low-frequency response. When more bass is needed, Deep Bass Mode maximizes system output, while Punchy Bass Mode provides a tighter and more energetic bass response.

Up to 34 Hours of Playback

The Boombox 4 provides up to 28 hours of playback on a full charge. Playtime Boost can extend battery life by up to six additional hours for up to 34 hours of listening. You can also connect the speaker to AC power for continuous playback.

Expand Your Listening Experience

Pair two Boombox 4 speakers together to create a larger soundstage with true stereo sound. Auracast lets you broadcast music to compatible JBL speakers within range without individually pairing each speaker.

Portable and Durable Design

The redesigned Boombox 4 is lighter than previous models and features an integrated carry handle for convenient transport. Its IP68 rating provides protection against water and dust, making it suitable for use in environments ranging from the bedroom to the backyard or beach.
