How to use

Turn the speaker on using the power control, enable Bluetooth on your source device and select "JBL Go 4" from the device list to pair. Use the volume control buttons on the speaker to adjust playback level. Before first use, fully charge the built‑in battery; while in use, monitor battery level on your source device if supported. Power off the speaker when not in use to conserve battery.

Usage recommendations

Place the speaker on a flat, stable surface for best sound dispersion. Keep the device within a typical Bluetooth range of your source device and avoid obstructions that may interfere with the connection. To minimise distortion, avoid sustained maximum volume given the mono 4.2 W output and charge the battery regularly to maintain consistent performance.
