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.
