Full review

We have tested many of JBL’s portable speakers, like the bass-heavy JBL Flip 4 and the smart JBL Charge 3. With JBL Boombox, they’ve taken everything they’ve learned from the travel speakers and dragged it to their extreme. The pringles size has increased to more than twice in all parts. But this is actually the lightest speaker in the test, so it’s very easy to carry it around in the comfortable carrying handle. You do not have to worry about it either, because it can withstand a short dip in the pool or to be snowed.

All the fine tunings can be made directly from the mobile app.

At the top you will find the usual volume, power and Bluetooth buttons. Everyone is raised so you can easily find them with your finger. There is also the JBL Connect button so you can connect more compatible JBL speakers. You can either connect two as a stereo or you can connect up to 100 (!) Speakers in the party mode. On the backside, the switch hides between indoors and outdoors. This can also be set from the JBL Connect app. There you can also choose whether the play button should function like that, or enable the voice assistant in the mobile phone, if the speakerphone is to be activated and if you want voicemail confirmations.

Despite the fact that the paper appears to have less power resources than the letters of some of the competitors, one should not be fooled by it. Boombox plays strong enough to make the neighbors angry. And with the two bass elements in the ends, it’s like having a portable subwoofer. At the beach party you can turn up the power to 11 by switching to outdoor mode. Something we do not recommend indoors, as the bass becomes deafeningly exaggerated. As expected, this is nothing for hi-fi ears, but if you have a more relaxed setting, it gives most of the music a compelling and festive boost. It is not at the expense of treble and middle registers, as they come well in the mix.


JBL has taken the essence of old-age boombox and made the best modern version of it. The size is fitting, the design is modern and it’s sufficiently easy to actually carry on it. It also has a battery that allows you to do it all day and night. Despite this context-sized format, Boombox has volume resources that hold and a little more. Together with the pounding bass you can start any party. You can even have pool parties since it’s waterproof and connect up to 100 pieces to cover an entire festival area. A clear favorite for summer parties.
