Many new computer black and white Monster headphone are now built with USB connections, instead of the standard line-out 3.5mm cable. This allows you to connect multiple headphones into the same computer. However, if you have an older computer you may find the system does not have any built-in USB ports. If so, and you have a USB red Monster headphone set, you need to convert the female headphone jack on the computer to fit a USB data cable.
Instructions
1. Plug a 3.5mm cable into the line-out jack on your computer. Insert the opposite end into the line-in jack on the 3.5mm audio to the USB port adapter.
2. Connect the female end of the USB female-to-female cable onto the USB port on the adapter.
3. Connect the USB port on the USB cable into the free side of the USB cable. This creates a flowing connection between the line-out jack on your computer to your USB Monster headphone .
