A:Answer We appreciate your inquiry. Our JBL Live 660NC headphones can be used with either a wired or wireless connection. For a wired connection, your computer needs a 3.5mm port, as the headphones come with a 3.5mm audio cable. For a wireless connection, your computer must support Bluetooth. To connect wirelessly, you need to turn on the headphones and press and hold the Bluetooth button until the LED flashes blue. Then, go to the Bluetooth settings on your computer and select the JBL Live 660NC from the list of available devices.
