Troubleshooting

If you have problems using this product, check the following points before you request service.

No power

• Put the earbuds back into the charging case, close the lid, and then open the lid to power on again.
• Recharge the earbuds (see "Charging").

2.4Ghz pairing failed between earbuds and 2.4Ghz USB wireless dongle

• Move the earbuds closer to the dongle. If the issue remains, pair the earbuds with the dongle again manually (see "To pair manually").

No sound or poor sound

• Make sure you have chosen JBL Quantum TWS as the default device in the game sound settings of your PC, Mac or gaming console device.
• Adjust volume on your PC, Mac or gaming console device.
• You may experience obvious sound quality degradation when using the earbuds near a USB 3.0 enabled device. This is not a malfunction. Use an extension USB dock instead to keep the dongle as far from the USB 3.0 port as possible.

In 2.4GHz wireless connection:

• Make sure the earbuds and 2.4GHz wireless dongle are paired and connected successfully.
• The USB-A or USB-C ports on some gaming console devices may be incompatible with JBL Quantum TWS. This is not a malfunction.

In Bluetooth connection:

• The volume control on the earbuds (customizable on the JBL Headphones app) does not work for the Bluetooth connected device. This is not a malfunction.
• Keep away from sources of radio interference such as microwaves or wireless routers.

UNABLE TO RECHARGE MY EARBUDS

• Recharge the charging case.
• Clean the charging pins on the earbuds and in the charging case (see "Cleaning the product").

My voice cannot be heard by my teammates

• Make sure you have chosen JBL Quantum TWS as the default device in the chat sound settings of your PC, Mac or gaming console device.
• Make sure the microphone is not muted.

I can't hear myself when I'm talking

• When using with a PC, enable sidetone via JBL QuantumENGINE to hear yourself clearly over game audio.
• When using with a mobile phone, adjust sidetone via the JBL Headphones app (see "Sidetone").

No response or malfunction of the earbuds

• Restore factory settings (see "Factory reset").
• Put the earbuds back into the charging case and close the lid. Wait for 10 seconds to finish hardware reboot before opening the lid to power on the earbuds again.

My earbuds fall off easily

• Try a pair of silicone ear tips that best fits your ear size. Adjust the earbud positions in your ears for the best fit (see "How to wear").
