Bluetooth wireless is very common in cell phone headsets and wireless keyboards and mouse devices. It is a low-power, moderately high-speed wireless communication protocol that is fast enough to carry high-quality audio signals. If you have a Bluetooth-enabled computer, you can configure it to output its audio signals to a Bluetooth headset or set of speakers, allowing you to listen to music and movies played in Windows Media Player anywhere within 30 feet of the computer.
Place the Bluetooth device in pairing mode. Bluetooth speakers and headphones usually have a "Connect" button somewhere inconspicuous; consult the product's manual for specific instructions on how to place it in "discovery" mode.
Open "Devices and Printers" from the computer's "Start" menu, and click the "Add a device" button in the window that opens.
Select the Bluetooth device from the list and enter its security pass key. Most devices use "0000" as a default password.
Right-click the volume control in the bottom right-hand corner of the Windows taskbar and select "Playback devices."
Click the Bluetooth device in the "Playback" tab, and click "Set Default." The Bluetooth device is now the computer's primary audio playback device.
Open WMP and play the file you wish to listen to. The audio should be played through the Bluetooth device.
