The JBL GO 4 outputs 4.2W of audio from a 45mm transducer. This IP67-rated chassis prevents dust entry and withstands submersion in shallow water. Compared to the GO 3, battery life increases from 5 to 7 hours, and the addition of the JBL Portable App allows for EQ adjustments.
The GO 4 increases battery life by 2 hours and adds app-based EQ control. It utilizes Bluetooth 5.3 for more stable wireless connections.
The battery provides 7 hours of standard use or 9 hours with Playtime Boost. High volume levels will reduce these estimated runtimes.
Auracast technology enables pairing two units for stereo output. You can also link multiple speakers for synchronized mono playback.
