There are several culprits that could explain why only one of your JBL earbuds is working. Here are some of the most common causes.

Connectivity Issues

Problems with the Bluetooth pairing between your earbuds and device are a prime suspect. Interference from other wireless devices can also disrupt the connectivity. Check that both earbuds are still paired and toggle your phone’s Bluetooth on and off. Also, move away from potential sources of interference like WiFi routers.

Hardware Malfunctions

Faulty internal components like frayed wiring can lead to one earbud not working. Inspect your earbuds closely for any cracks or damage. Wear and tear over time can also cause the speakers to malfunction. Think about how long you’ve owned them and how much use they’ve gotten.

Battery Problems

If one earbud isn’t charging properly, it can easily run out of battery faster. Try charging your earbuds for at least two hours and check if both earbuds are charging fully. Uneven battery lifespan between the two earbuds could also explain the issue.

Software Glitches

Outdated firmware or compatibility issues with your device can prevent one earbud from working properly. Update your JBL earbuds to the latest firmware from the JBL Headphones app. Also, check if a software update for your smartphone, tablet, or computer could improve connectivity.

Follow these troubleshooting steps to pinpoint why only one JBL earbud is working.

Check Connectivity

Start off by repairing your earbuds with your device. Go into your Bluetooth settings and delete the existing pairing. Then select “Add New Device” and choose your JBL earbuds again. This refreshed pairing might resolve any glitches.

Also switch between different audio sources like your phone, laptop, or tablet and test if one earbud works across devices. Move closer to the audio source and away from potential interference to improve connectivity.

Inspect for Hardware Damage

Closely inspect each earbud and the connectors for any signs of damage or worn parts. Test the earbuds with different audio sources to isolate whether it’s an internal hardware issue or just a problem with one device. Check if issues persist for one earbud across all gadgets.

Battery and Charging Checks

Empty batteries are often the issue with wireless earbuds. Charge your JBL earbuds for at least 2 full hours using the supplied USB cable. Check the indicator lights to confirm both earbuds are fully charging. Leaving them docked for longer can also help redistribute battery life evenly.

Software and Firmware Solutions

Update your earbuds to the latest firmware in the JBL Headphones app. Connect them to your phone or tablet, launch the app, and follow the on-screen updating prompt. Upgrading to the newest firmware optimizes performance and can fix bugs.

You can also reset the earbuds to factory settings to refresh the software. Just press and hold the power button on each earbud for 10-15 seconds until the LED light flashes red and white. Then repair the earbuds with your device.
