JBL Boombox 4 vs Boombox 3: Louder, Smarter & Built for Fun

Hunting for the ultimate speaker to fuel your next big gathering? We're comparing the beloved JBL Boombox 3 vs the brand-new, next-gen JBL Boombox 4 to find out which portable speaker will absolutely dominate your party playlist.


Whether it's a spontaneous rooftop BBQ at your KL condo, a chill session at Genting, or an epic beach getaway to Langkawi, we're here to help you discover the perfect JBL sound. Check out how the Boombox 4 takes the party up a notch, ensuring every single beat hits differently.

Pure Party Power and Precision

This is where JBL's sound-science shines brightest. Take a look at the difference in transducers to compare the sound of JBL Boombox 3 vs Boombox 4:

  • JBL Boombox 3: 1 subwoofer, 2 midrange, 2 tweeters

  • JBL Boombox 4: 2 woofers, 2 tweeters, 3 passive radiators

While the JBL Boombox 3 delivers a rich, powerful sound, the Boombox 4 is designed to be louder and punchier. You'll feel a deep bass rumble and a sound that just hits differently; it's fuller, cleaner, and ready for serious volume.


But the biggest leap forward? That's our exclusive AI Sound Boost technology. This JBL technology analyses your music in real time and adjusts the acoustics to reduce distortion, even when you crank the volume all the way up. That's how the Boombox 4 delivers concert-level sound wherever you go, ensuring every beat is crisp and clear.

Maximum Battery Life for Maximum Fun

Need to keep the good times rolling well past midnight? Both speakers deliver exceptional endurance, offering massive battery life. The Boombox 3 offers up to 24 hours of continuous playtime, while the Boombox 4 steps up its game, offering up to 28 hours on a single charge plus an extra 6 hours with Playtime Boost.


That's enough power for a full, spontaneous weekend trip from KL to Penang; no charging needed until you get home!


The Boombox 4 also features a replaceable rechargeable battery. This means your music never has to stop; swap in a new battery, and your JBL Boombox 4 is back at 100% juice.

Built for Malaysia's Weather

Malaysia's weather is beautiful, but it's famously unpredictable. One moment you're enjoying a sunny poolside BBQ, the next, a sudden downpour hits. That's why you need a portable speaker that's built for the unexpected.


Just like its predecessor, the Boombox 4 is dustproof and waterproof. But when you compare the JBL Boombox 3 vs the Boombox 4 in terms of durability, the Boombox 4 takes durability up a notch with an IP68 rating. This means it offers even greater resistance to dust and immersion than the Boombox 3's IP67 rating.

Same Power, Less Bulk

While both speakers may sound and look bigger, the JBL Boombox 4 is designed to be portable. Weighing in at only 5.89kg, the Boombox 4 is nearly a full kilogram lighter than the JBL Boombox 3 (6.7kg). That's a huge weight difference!


It still has the same bold, iconic silhouette and massive presence, but it's much easier to hold and grab-and-go for staycations, long drives up the coast, or picnic weekends.

More Ways to Turn Up the Bass

The Boombox 3 pumps the kind of deep bass that you feel in your soul, but the Boombox 4 plunges even deeper and adds a cool glow to match the mood!


Thanks to the Dual Bass Boost settings built right into the Boombox 4, you get complete control over your sound. Hit the Bass Boost button once to see the JBL Horn mark light up orange for Deep Bass mode, or hit it twice to turn it white for Punchy Bass mode.

Connectivity That Just Works

While the Boombox 3 relied on the PartyBoost system, the JBL Boombox 4 steps into the future with Auracast™, the next-gen multi-speaker technology. Auracast™ enables easier, more seamless syncing with even more compatible JBL speakers over greater distances.


Both models still support the JBL Portable app, allowing you to fine-tune how your tracks sound with a customisable equaliser. Plus, the Boombox 4 features an upgraded Bluetooth 5.4 (vs 5.3 in the Boombox 3) for faster, more stable pairing with your smartphone or tablet.

For the Audiophiles

If you're one of those who demand sound quality that goes beyond standard Bluetooth compression, the JBL Boombox 4 introduces a serious game-changer: Lossless audio playback via the USB-C port.


This is a hyper-high-resolution sound that preserves every teeny-tiny detail of the original recording. You'll hear every cymbal's shimmer, every vocal nuance, and the subtle texture of every guitar strum in pristine clarity.

The Final Verdict: Boombox 3 is Solid, But Boombox 4 is Superior

The JBL Boombox 3 remains a phenomenal, powerful portable speaker that still commands any party with its strong sound and impressive battery life. However, the JBL Boombox 4 has everything fans adore — just louder, lighter, longer-lasting, and much smarter with Auracast™ and AI Sound Boost.


Whether it's an upcoming open house, a spontaneous beach trip to Port Dickson, or a weekend BBQ, the Boombox 4 is designed to keep the energy flowing longer and clearer.
