JBL Boombox 4 Portable Bluetooth Speaker – Black

The all-new JBL Boombox 4 is bigger, bolder and better than ever, with powerful JBL Pro Sound that stays loud and clear with deep, thumping bass. Two bigger woofers, two tweeters and three passive radiators mean every track hits harder and sounds cleaner — and at up to 34 hours of playtime, it is built to keep the party going.

Key Features of the JBL Boombox 4

JBL Pro Sound with AI Sound Boost

Two Bass Boost modes

Switch between Deep Bass and Punchy Bass modes from the top panel to match your mood and your music.

Multi-speaker sound with Auracast

Stereo pair two Boombox 4 speakers for a wider soundstage, or link multiple Auracast-enabled JBL speakers to cover more ground with the same playlist.
