SHERIDAN, WYOMING – December 17, 2025 – JBL is turning up the energy again with the JBL Boombox 4, a new take on its iconic portable speaker built to shake rooms, fuel parties, and keep people together through big, confident sound. Introduced in Garching, the Boombox 4 leans into what fans already love—bold bass and go-anywhere vibes—while adding smarter audio tech, more battery power, and tougher outdoor protection for real-life use.
A Familiar Idea, Dialed Up for 2025
JBL describes the Boombox 4 as “back” and “more powerful than ever,” aiming for a speaker that fits everything from living-room hangouts to outdoor adventures. The core promise is simple: legendary JBL Pro Sound with clear highs, deep lows, and strong dynamics—whether you’re playing mellow background playlists or trying to get a whole group moving.
What makes this model feel like more than a small refresh is the blend of sound, portability, and durability—the stuff people actually notice after the first “wow” moment.
AI Sound Boost: Smarter Power Without the Mess
One of the headline upgrades is AI Sound Boost, which JBL calls an intelligent sound optimization designed to help the drivers deliver more performance without losing clarity. In everyday terms, the goal is that “loud” stays enjoyable—not harsh, muddy, or distorted—especially when the party gets louder and the music competes with conversation.
If you’ve ever owned a speaker that sounds great at 30% volume and chaotic at 80%, this is the exact pain point JBL is trying to solve here.
Bass Boost You Can Feel—and Now See
JBL is also making bass a full-on feature moment. With Bass Boost, you can pick between two modes depending on your vibe:
- Deep Bass for a fuller, richer low end
- Punchy Bass for tighter, more energetic bass that suits upbeat tracks
And in a fun “party speaker” twist, JBL adds illuminated JBL logos that can appear in white or orange depending on settings—so the bass becomes a visual cue too, not just something you feel in your chest.
Lighter to Carry, Stronger to Last
Portability is a big part of the Boombox identity, and JBL says the Boombox 4 is almost 1 kg lighter than its predecessor, making it easier to carry, store, and bring along wherever the action is. At the same time, JBL claims almost 50% more battery performance compared to the Boombox 3—framed as “less weight, more power.”
For longer sessions, JBL lists:
- Up to 28 hours of battery life
- Up to 34 hours with Playtime Boost
- A replaceable battery (sold separately)
Built for Outdoors: IP68 and a Tougher Stand
The Boombox 4 is designed to be a true outdoor companion, with a reinforced stand and an IP68 water- and dustproof housing. That’s the kind of spec that matters in real life—beach days, parks, camping, sudden weather shifts, and the occasional spilled drink that always seems to happen right next to the speaker.
Auracast™ for Bigger Sound With Your People
When one speaker isn’t enough, the Boombox 4 includes Auracast™ for quick stereo or multi-speaker connections with compatible JBL speakers. It’s a very “group-friendly” feature—because bigger gatherings usually need bigger sound, and nobody wants to spend 20 minutes troubleshooting pairing while the mood fades.
Editorial Extra: 3 Quick Ways the Boombox 4 Fits Real Life
- The outdoor day that turns into a night: IP68 protection and long playtime are made for plans that keep expanding.
- The “one speaker, many moods” setup: Switch between Deep Bass and Punchy Bass depending on whether you’re hosting dinner or dancing.
- The instant-upgrade party move: Link compatible speakers via Auracast™ when you want more coverage without complicated setup.
What JBL Says About the Trend
JBL is also positioning the Boombox 4 as a response to what people want right now—portable speakers with bigger bass. As Carsten Olesen, President of Consumer Audio at HARMAN, put it: „The market is trending toward portable speakers with more powerful bass – and JBL is the master when it comes to bass,“ so Carsten Olesen, President of Consumer Audio at HARMAN. „Finding the balance between powerful bass and high-quality audio is an art that is difficult to master. With the introduction of proprietary technologies like Bass Boost and AI Sound Boost, the JBL Boombox 4 achieves this perfectly. It combines everything that fans love about JBL.“
The JBL Boombox 4 is available from September 8 in black, blue, and camouflage, with a recommended price of €499.99 (and CHF 499.95) on JBL.com.
