You can use your Logitech UE 9000 Wireless Headphones with your computer. Here's how:

Windows

1. Place your wireless headphones in Bluetooth pairing mode (see answer 360023411253 for help).
   NOTE: If this is the first time you're using your headphones, they will already be in pairing mode out of the box.

2. Enable the Bluetooth adapter on your computer and then add a new device (see your computer's documentation for help).

3. On the Bluetooth device menu, find UE9000 and add it. Your computer will pair and connect, and it will install the drivers needed for this device.

4. After the headphones have been added, and the drivers finish installing, it can take a minute or two to connect.

5. Once the connection is complete, you may need to select your wireless headphones as the default input and playback device for your computer before you can use them.

Macintosh

1. Place your wireless headphones in Bluetooth pairing mode (see answer 360023411253 for help).
   NOTE: If this is the first time you're using your headphones, they will already be in pairing mode out of the box.

2. Enable the Bluetooth adapter on your Macintosh and then set up a new Bluetooth device (see your computer's documentation for help).

3. On the Bluetooth device menu, find UE9000 and add it. Your Macintosh will pair and connect to it.

4. Once the wireless headphones have been added, you may need to select them as the default input and output device before you can use them.
   NOTE: When you set your wireless headphones as the default output device, you also need to select UE9000 Stereo for listening to music, and UE9000 for using it in chat applications, like Skype.

You can also connect your headphones to your computer with the optional 3.5mm cable (included) for audio only, but the controls and microphone won't work.
