You can pair up to eight Bluetooth devices with your wireless headphones, but can only maintain an active connection to one device at a time.

To pair additional devices:

• Activate Bluetooth on your device (see your Bluetooth device's documentation for help).

• Turn your headphones on by sliding the power switch up toward the Bluetooth symbol.

• Press and hold the Bluetooth connect button (on the bottom of the right ear cup) until the headset status light blinks green rapidly.

• Locate and select the "Logitech UE 4500" option on the Bluetooth device menu (see your Bluetooth device's documentation for help).
  The headset status light turns solid green when the Bluetooth connection is successful.

NOTE: When switching from one device to another, make sure you disconnect from the last device before connecting to the next one (see your Bluetooth device's documentation for help).
