Multi-speaker connection by Auracast™

Wouldn't it be great to share the whole mood with the whole crew? With Auracast™, effortlessly stereo pair two Boombox 4 speakers for a wider sound stage or connect multiple Auracast™-enabled JBL speakers to cover more ground with the same playlist.

Two Bass Boost settings to match our vibe

When it comes to bass, we like having options. Fire up the JBL Boombox 4 and you’ll get that classic JBL signature bass we all love. Want to take it deeper? Hit the Bass Boost button on the top panel—the JBL Horn mark glows orange, and boom, you’re in Deep Bass mode, where those two woofers and three passive radiators go all in. Want something tighter and more energetic? Tap the button once more, the Horn mark turns white, and you’re in Punchy Bass mode. Whatever the mood, we’ve got the bass to match.

Bigger and louder, but lighter

The JBL Boombox 4 sounds bigger and better than ever—but here’s the real win: we redesigned it to be lighter than before. So now it’s way easier to set the tone wherever we go.

Lossless audio playback
