Bluetooth has been present for quite a while now. Many have embraced it whereas many have not. You might find laptops that do not have Bluetooth pretty installed. So what would you do in case you need to use a Bluetooth headphone?
In this case one can use a Bluetooth adapter. It is a small usb device which you would plug it into a USB port of your computer. There is no Installation involved or drivers for that matter. One could get a Bluetooth adapter for as low as low as 12 dollars.
