If you're having trouble with the microphone on your wireless headphones try the following:

• If you're using the headphones in wireless mode, disconnect any devices from the 3.5mm auxiliary connection. The built-in ear cup microphone won't work with a device connected to this jack.

• Make sure your Bluetooth device is within the range of your wireless headphones.

• Check that your phone is in headset mode and mute hasn't been activated.

• Turn off your wireless headphones, restart the Bluetooth connection on your device, and then turn the headphones back on.

  NOTE: Your headphones may have limited functionality with some smartphones.
