What to do
• Use a different music source.
• Pair a different mobile device.
• Disconnect the second mobile device.
• Move the device closer to the headphones, and away from any
interference or obstructions.
• Clear any debris or wax buildup from the earbuds and headphone
nozzles.
• Make sure the power is switched on. The power indicator should glow
solid green.
• Turn the headphone's power off and then on again.
• Charge the headphones.
• Open the hinged door on the inside right neckband and securely
connect the small end of the USB cable to the USB connector. Make
sure the connector on the cable is correctly aligned with the connector
on the headphones.
• Secure both ends of the USB cable.
• If your headphones have been exposed to high or low temperatures,
let the headphones return to room temperature and then try charging
again.
Securely attach the tips to the earbuds (see "Changing the StayHear®+
QC® tips" on page 15).
