Is the JBL Boombox 4 worth it over the Boombox 3?

The Boombox 4 adds Auracast, lossless USB-C audio and a lighter build while keeping the loud JBL sound. If you already own a Boombox 3, the upgrade matters mainly for pairing and wired lossless playback.

How long does the battery last?

JBL rates it at up to 28 hours on a full charge. Loud volume and Bass Boost will shorten that, and you can run it on AC power for nonstop play.

Can I pair two Boombox 4 speakers?

Yes. Two units can be paired for stereo sound, and Auracast lets you broadcast to multiple compatible JBL speakers.

It carries IP67 and IP68 ratings, so it resists dust and survives being submerged briefly. It is built for poolside and beach use.

Does it have an app or Wi-Fi?

No. There is no app control, EQ or Wi-Fi streaming. You control volume, play and skip with physical buttons and connect over Bluetooth 5.4.

You get the speaker, a USB-C charging cable and documentation. A USB-C port also handles lossless audio from a wired source and charges other devices.
