JBLBOOMBOX 4 PORTABLE BLUETOOTH SPEAKER 2025

More Power Seems Inevitable

With each update to the Boombox series, it’s gotten a boost in power output, and this is likely to continue with the release of the Boombox 4. This is further supported by the fact that recent releases like the Xtreme 4, Flip 7, and Charge 6 also all got boosts to their output, albeit in some cases, marginal.

We initially published this article suggesting we’d see a power output of between 200 and 220 watts, and not to brag, but it seems the early data leaks suggest a peak output of 210W, living up to expectations and giving a noticeable boost compared to the Boombox 3.

Major Changes to Battery Design

Early information suggests that the Boombox 4 will get a significant overhaul to its battery design, with the ability to remove and replace the battery. This is something we’ve seen JBL introduce to the PartyBox line over the last year or two, but we didn’t expect to see it on the Boombox 4.

Apparently, the Boombox 4 will have two variants – one with a longer battery life than the other. It’s not clear yet whether both models will have replaceable batteries or if that is limited to one of the two designs.
