We turn it up our way—anywhere. 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. AI Sound Boost analyzes our music in real time and adjusts the sound to give us more power with less distortion, even when we turn it all the way up. It packs two bigger woofers, two tweeters and three passive radiators, so every track hits harder and sounds cleaner. When we want to fine-tune the vibe, we just switch between deep or vibrant punchy Bass Boost settings to match our mood. We gave the classic Boombox design a fresh upgrade—it’s larger but lighter, so we can take it wherever the party goes: the beach, the block, or the backyard. It’s IP68 waterproof and dustproof, so weather’s never a dealbreaker. And, with up to 34 hours of playtime (thanks, Playtime Boost), we’re set for the long haul. With the JBL Boombox 4, we carry the mood and the energy, everywhere we go.

GREAT SPEAKER
Speaker is versatile, has really good sound and really great bass when the feature is turned on. Battery last long, easy to set up & easy to paid with other late jbl models. perfect for your house, apartment, party, or small get together . Only downside is sound quality can get a little distorted when playing at full volume.

Opinion on JBL
This boombox packs a punch of base sound. The sound quality is very good. I really like the app and all the different sound settings for the speaker. The handle is perfect for portability and the designs of the speaker is looks better than any other speaker on the market. Lastly, the Aura cast feature that allows you to be able to connect other compatible speakers is an awesome feature. My overall opinion of this JBL Boombox 4 is that it is a great product.

JBL BOOMBOX 4
I just received my JBL Boombox 4 through UPS in just 3 business days. Not only was my product shipped to me fast but the box was much bigger than I expected. After testing the sound on this boombox I realized this boombox sounded a lot more like a kicker I had installed in a car. This boombox is off da wall, Seriously, all these comparisons they advertise on YouTube are garbage. No more comparing because if you ain’t got JBL, you ain’t got a boombox. Not only does this boombox have superior sound, but it has bass that bumps just as loud as my JBL 1300 & it’s portable. You got to get this…
