JBL Go 4 - Ultra-Portable Bluetooth Speaker

Big JBL Sound in the Palm of Your Hand

The JBL Go 4 proves a speaker doesn't need to be big to sound good. Despite its palm-sized footprint, it delivers punchy bass and clear JBL Pro Sound, making it an easy speaker to toss in a bag for a walk, a picnic or a day at the pool. The bold, colorful design and integrated loop mean it's as much a style statement as it is a piece of audio gear.

An IP67 rating makes the Go 4 fully waterproof and dustproof, so splashes, sand and the occasional dunk in the pool aren't a concern. A single charge delivers up to 7 hours of playtime, extended by another 2 hours with the built-in Playtime Boost feature, and Bluetooth 5.3 keeps the connection reliable across multiple devices. Pair two Go 4 units for true stereo sound, or link several JBL Auracast-enabled speakers together for a bigger listening setup.
