CONNECT THE AUDIO CABLE
Use the 2.5 mm to 3.5 mm audio cable to listen to audio from your source device
when a Bluetooth connection isn't available.
NOTES:
• The headphones must be powered on for you to use the audio cable. If the battery
is depleted, use the USB cable to connect to an external power source, then power
on the headphones (see page 34).
• Phone calls and media playback controls are disabled and must be controlled on
your source device.
• Bluetooth connection and microphone voice pick-up on the earcups are disabled.
• For the best experience, a Bluetooth connection is recommended.
1. Connect the cable to the 2.5 mm port on the left earcup.
2. Connect the other end of the cable to the 3.5 mm port on your source device.
