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.
