Compare the JBL Boombox 3 vs Boombox 4: Unpacking All the Upgrades

Looking to bring the vibes to your next hangout? We're comparing the beloved JBL Boombox 3 vs the brand-new, next-gen JBL Boombox 4 to shine a spotlight on all the powerful new features and innovations you can't miss.

Whether you're looking for a portable speaker for poolside BBQs, beach picnics, chalet gatherings, or epic house parties, the Boombox 4 is here to do it all. Check out how the Boombox 4 makes some major noise and why it’s the perfect speaker for your listening needs!

This is where JBL's sound-science truly shines. Take a look at the transducer differences to compare the sound of the JBL Boombox 3 vs Boombox 4:

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

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

While the Boombox 3 delivers a rich, powerful three-way sound, the Boombox 4, with its increased wattage and new drivers, is designed to be louder and punchier. You'll feel the deep bass rumble and hear richer, cleaner details, making every track sound phenomenally better.

We also added AI Sound Boost, our exclusive tech that analyses your music and adjusts the acoustics in real time to reduce distortion, even at max volumes. From East Coast Park to Siloso Beach, your playlist will sound stadium-ready.

Need to keep the party going all night? Both speakers deliver exceptional endurance, offering massive battery life. The Boombox 3 gives you up to 24 hours of continuous music, while the Boombox 4 steps up to deliver up to 28 hours plus an extra 6 hours with Playtime Boost! This exceptional runtime is perfect for party animals or those who love spending the entire day outdoors, ensuring your soundtrack lasts as long as your adventure.

The Boombox 4 also features a replaceable battery, making sure the music never truly stops, even when the sun rises.

Rain or shine, these speakers are unstoppable. Both of these wireless outdoor speakers are built for the unexpected. The JBL Boombox 3 features an IP67 rating, meaning it's fully waterproof and dustproof, ready for any pool or beach gathering in Singapore. 

However, when comparing the Boombox 3 vs Boombox 4, the Boombox 4 takes durability up a notch, upgrading to an IP68 rating, which offers even greater resistance to dust and immersion. Even if you’re out on a round island cycling loop or navigating a sudden downpour, the Boombox 4 can handle it all.

While the JBL Boombox 3 weighs in at 6.7kg, the JBL Boombox 4 manages to shed serious weight, coming in at only 5.89kg — that's nearly a full kilogram lighter! But the Boombox 4 still keeps the same bold, iconic silhouette that's easy to grab and go for staycations, beach days, or cycling meet-ups.

The JBL Boombox 3 pumps the kind of bass that you feel, but the JBL Boombox 4 takes that excitement even deeper and adds a cool glow to match the mood!

Now, with Dual Bass Boost settings built right into the Boombox 4, you can perfectly match the sound to your vibe. Just 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.

If you use your speaker for both casual listening and dance parties, these new bass modes are perfect for switching subtle background tracks into explosive, rhythmic sound.

The JBL Boombox 4 steps into the future with Auracast™, its next-gen multi-speaker tech, leaving behind the reliable PartyBoost system of the Boombox 3. Auracast™ allows for easier syncing with more compatible JBL speakers across greater distances. If you're by the pool or the BBQ pit, you can link multiple speakers and have them all playing the same track in perfect sync.

Both models also support the JBL Portable app to fine-tune how your tracks sound, and the Boombox 4 features an upgraded Bluetooth 5.4 vs 5.3 in the Boombox 3 for faster, more stable pairing.

The JBL Boombox 4 introduces a game-changer for music purists: Lossless Audio Playback via the USB-C port. For those who love to hear every cymbal, strum, and vocal nuance, this is hyper-high-resolution sound that standard Bluetooth compression simply can't touch.

The JBL Boombox 3 is a remarkable portable Bluetooth speaker for anyone, but the Boombox 4 is definitely worth the upgrade with heavier bass, smarter tech, and a longer battery life. Whether you're enjoying a picnic at Marina Barrage or planning a coast-to-coast cycling trip, the Boombox 4 is engineered to keep the energy going.

Here is a side-by-side comparison to break down everything that’s new:
