JBL ENDURANCE-SPRINT user manual

To increase the volume on your JBL Endurance SPRINT, follow these steps:
1. Make sure the earphones are properly connected to your device.
2. On your connected device (such as a smartphone or tablet), navigate to the settings or control panel.
3. Locate the volume control/slider. On most devices, this can be found by swiping down from the top of the screen (on Android) or swiping up from the bottom (on iOS devices) to reveal the quick settings panel.
4. Adjust the volume slider to increase the volume level. Alternatively, you can use the physical volume buttons on your device if available.
5. Ensure that the volume on your connected device is turned up to the maximum level.
If you've followed these steps and are still having trouble with low volume, make sure that the volume on the JBL Endurance SPRINT earphones themselves is also set to maximum. You can adjust the volume directly on the earphones by pressing the volume up button located on the right earpiece.

The JBL Endurance SPRINT headphones are advertised to have a battery life of up to 8 hours on a single charge.
