Connect the audio cable and microphone

The 2.5 mm to 3.5 mm audio cable has a built-in microphone. You can use the audio cable for phone calls or listening to audio on your source device when a Bluetooth connection isn’t available, the headphone battery is depleted, or the headphones are powered off.

Making your audio connection

  • When the audio cable is connected, Bluetooth connection and the microphone voice pick-up on the earcups are disabled
  • When the audio cable is connected and the headphone battery is depleted or the headphones are powered off, the headphone controls are disabled. Phone calls and media playback must be controlled on your source device. For the best experience, a Bluetooth connection is recommended.
 
  1. Connect the cable into the 2.5 mm port on the left earcup.
  2. Connect the other end of the cable into the 3.5 mm port on your source device
